Abstract

A differential mechanism is arranged below an infinitely variable transmission and a reduction gear mechanism. Front fitting parts and rear fitting parts for fitting suspension arms to a vehicle frame are arranged to the front and rear of the deferential mechanism. Even though the left and right suspension arms swing up and down, or a transmission and a reduction gear mechanism attached on a vehicle frame swing left and right with respect to the suspension arms, there is no interference of the transmission and the reduction gear mechanism with the suspension arms due to a space at the front and the rear of a differential mechanism, so that the vehicle frame can swing left and right and it is also possible to easily constitute a vehicle having an independent suspension.

Abstract

A three wheeled vehicle comprises a two wheeled rear frame carrying an engine and transmission and a front frame pivotably connected at two points to the rear frame whereby a steerable front wheel is tilted and whereto a seat is mounted. The vehicle negotiates corners by a combination of front wheel tilting and steering. The pivots are preferably aligned with each other and with the front wheel road contact point. The rearward pivot is behind and above the seat, which may be inside an enclosure. Foot pedals allow a driver to mechanically control tilting and righting of the front frame. Centring of the tilt mechanism may also be assisted by the inertia of the driver's body and by a spring and damper on left and right sides. Rear shock absorption is also provided. The trike is sufficiently stable to be capable of travelling in a straight line even when the front frame is tilted to one side.

Abstract

Mechanism for the construction of a three-wheeled vehicle with front rolling part (1). The front part of the vehicle is linked to the rear part (8) by a four-sided mechanism. During movement on a bend it is inclined as normally takes place in two-wheeled vehicles, and the rear part is not involved in the rolling movement. The mechanism is made up of four members: one member known as the front frame (2) is connected to the front rolling part of the vehicle, a second member known as the rear frame (5) is connected to the non-rolling part of the vehicle, and the other two members (3,4) that link the two frames determine the position of the roll axis (y) of the front member with respect to the rear. The plane (v) on which the mechanism is positioned is perpendicular to the longitudinal plane of the vehicle. Variants will be produced.

Abstract

The invention relates to a vehicle (1) provided with a frame having two frame sections (3, 4) which are able to tilt with respect to one another. An opposite lock power transmitter (50) is connected to a steerable front wheel (13). The opposite lock power transmitter (50) is controlled as a function of the tilting moment on the frame sections (3, 4). By this means application of opposite lock is achieved, as a result of which the tilting section of the vehicles "drops into the bend" more rapidly and as a result of which increased manoeuvrability is obtained. The opposite lock power transmitter (50) can be used on vehicles having an active tilting system with drive means, such as, for example, hydraulic tilting cylinders (9, 9'), which are controlled by a sensor depending on the radius of the bend (24).; The tilting moment generated by the tilting cylinders (9, 9') can optionally serve as a control signal for the opposite lock power transmitter (50). As a result of the active application of opposite lock, the tilting cylinders (9, 9') can be of relatively small construction.

Abstract

The invention relates to a vehicle (1) provided with a frame (2) having a front frame part (3) and a rear frame part (4) which can tilt with respect to one another. The vehicle (1) comprises three or more wheels (7, 7', 13), it being possible to rotate the front wheel (13) with respect to the steering column (18). In this case, a sensor (24) determines the angle of rotation between the front wheel (13) and the steering column (18) and, as a function of this angle of rotation, actuates the tilting means (9, 9') of the vehicle. As a result of the consequent tilting of the front frame part (3) and as a consequence of the speed at which the vehicle (1) is travelling, the front wheel (13) and the tilting angle will automatically adopt the correct level for allowing the vehicle (1) to travel through the bend in a stable manner at the given speed.; Controlling the tilt via the difference in angular rotation between the steering column (18), which is flexibly connected to the front wheel (13), and the front wheel (13), it is possible to control the tilt in a simple and robust manner.

Abstract

The invention relates to a vehicle, equipped with a carrying section with a front wheel and a driving section , that freely turns around a lengthwise axis line in a loaded state from the driver's section situated above the centre of gravity of it, as a result of which the driver section will spontaneously assume a slope depending on the turning radius and speed of the vehicle when executing a turn. The vehicle is consequently extremely stable. In addition the driver's section can contain a wheel that can be steered and the axis over a contact point of this wheel is situated with a base, which further increases the turning stability of the vehicle in bends.

Abstract

PURPOSE:To provide restoring force with a large oscillating angle in vertical or horizontal direction and no movement of an oscillating fulcrum regardless of a small design of a motor tricycle by making the relative oscillating amounts of a shaft to the outermost cylindrical body equal to the sum of all the respective relative oscillating amounts of the innermost cylindrical body and mutually adjoining cylindrical bodies. CONSTITUTION:The relative oscillating amount of a shaft 20 to the outermost cylindrical body 14 becomes the total sum of the relative oscillating amount of the outermost cylindrical body 14 to a middle cylindrical body 16, the relative oscillating amount of the middle cylindrical body 16 to the innermost cylindrical body 18 and the relative oscillating amount of the innermost cylindrical body 18 to the shaft 20.; As a result, the shaft 20 and the outermost cylindrical body 14 can be relatively oscillated against the elastic force of rubbers 22, 24, 26 within the maximum oscillating range of 30 + 30 + 30 = 90 degree. Moreover, elastic energy is accumulated by elastic deformation of rubbers 22, 24, 26 due to relative oscillation, and after rear wheels 9, 9 rides across roughness, restoring force is generated by the elastic energy. It is thus possible to provide the optimum restoring force by selecting the material of rubbers 22, 24, 26 and so forth.

Abstract

In order to eliminate the risk of the motorcycle falling over and the three-wheeled vehicle tipping over, the two rear wheels of the scooter with a cab swing parallel to the plane of symmetry of the vehicle, the style of driving the motorcycle is preserved, the vehicle enters at an inclination (optionally up to a stop) into the curve. In the position of rest, the vehicle is locked against inclination to the side, it behaves, likewise in first gear, as a three-wheeled vehicle. On changing up to second and the higher gears the lock is released, the vehicle then behaves as a motorcycle. When changing down to first gear the lock again comes into operation, the vehicle can be parked as a three-wheeled vehicle. By means of two pedals coupled to the rear wheels the driver may at any time also have an influence on the position of the vehicle. The feet are no longer used for support on the ground, the vehicle may be provided with any desired protection against the weather up to the vehicle body being fully closed (with heating), already tested in 1946 (including two people spending a night in the vehicle).

Abstract

A parking locking system for an articulated or swing-type tricycle. A parking lever mounted to the handlebars of the steerable wheel actuates a cable and a rod. The rod engages a spring loaded slideable pin member into a hole in a plate fixed to the front frame of the steerable wheel. If the pin is not aligned with one of the holes in the plate, the spring will deform and the pin will slide relative to the rod. Upon further rotation of the front handlebars to a position where the pin member is aligned with a hole, the compression in the spring will cause the pin to interengage with the fixed plate thus locking the front steering wheel. The actuation of the cable interengages locking arms with a plate attached to the front of the swing shaft and with a parking gear in the drive train, respectively.; A spring-loaded lever resisting interengagement of the locking arms is used to create tension in the cable and retract the locking arms when the parking lever is deactivated.

Abstract

A rear-wheel suspension device on a tricycle vehicle having front and rear vehicle portions interconnected by a rolling joint having a sleeve bearing. To provide increased stability between a pair of rear wheels of the tricycle vehicle, a casing of the rolling joint is pivotably mounted on a frame of the front vehicle portion for pivotable movement. The rolling joint has a spindle connected in a fixed positional relationship relative to axles of the rear wheels. A shock absorber is interposed between the frame and the casing. To increase damping and vibration-isolating ability, the casing is pivotably connected to the frame by a link, and the shock absorber is oriented so as to be substantially perpendicular to a straight line passing through an axis of the rear-wheel axles when they are loaded and a pivot point at which the link is pivotably connected to the casing.; The link and the shock absorber have respective longitudinal axes extending substantially parallel to each other, and an engine is oriented such that major vibrations thereof are produced in a direction substantially at a right angle to the aforesaid longitudinal axes.

Abstract

A position adjusting means of a link mechanism which hangingly supports a swing joint in three-wheeled motor vehicle having front body laterally swingable relative to a rear body. The position adjusting means includes a pair of flexible stops, one being positioned behind one end of a sleeve member which supports a pair of link members, and the other being positioned in front of the sleeve member. These stops are mounted onto a pair of frame members positioned in the front body and extending in parallel along travel direction of the vehicle, or mounted onto one of said frame members so as to position at least one end of said sleeve between the stops. The link members each have an upper end integrally connected to a supporting member and a stop is secured to the lower surface of each supporting member.; The supporting members extend in horizontal plane and opposite direction relative to the sleeve along travel direction of the vehicle. The sleeve supports the pair of link members and is concentrically supported by a pivotal shaft through rubber bushes. The both ends of the pivotal shaft is secured by a pair of brackets mounted on the pair of frame members. Upon placement of the stops onto the frame members, the link members provide vertical orientation.

Abstract

The device in accordance with the invention operates and controls the tilt of a body of a vehicle and is operated by a driving shaft driven in rotation by movement of the vehicle. A rocking mechanism that is capable of being driven in two opposite directions by the driving shaft employs two disengageable coupling assemblies to operate rocking of the body, each in one direction. Progressive engagement of one or other of the coupling assemblies is operated directly by a pendular mass. Deviation of the latter to one side or the other of a plane passing through its axis of oscillation and parallel with the median plane of the body, causes progressive engagement of that one of the two coupling assemblies.; This causes rocking of the body in a direction which enables the median plane of the latter to be brought back into the direction of the apparent vertical passing through the axis of oscillation and the center of gravity of the pendular mass.
