Abstract

The present invention offers a front suspension and steering system for cycles and motorcycles. A mainframe (116) with two front wheels (102,104) and one rear wheel (108), the front wheels (102,104) have flat surface tires, a 2-axial hub, having a wheel axle (110) to support the two front wheels (102,104) and a tilting axis (204) below the wheel axle (110), a steering arm, having a tilting axle, the tilting axle can rotate in the tilting axis (204) when the steering arm is tilting, the steering arm is connected to the mainframe by two wish bones (118) and can rotate in the steering axis. During turning, the body and the rear wheel (108) are tilting to the side of turning to keep the center of gravity on the side of turning to balance the centrifugal force, but the front wheels (102,104) and the 2-axial hub do not tilt, such that it is more stable and safe during turning.

Abstract

The device has a non-motorized passive articulation (300) permitting inclination of an movable frame (200) with respect to a front steering axle or rectangular chassis (100), and locking units constituted of double effect jacks (400) for locking the passive articulation. An accelerometer (500) is arranged on the movable frame for measuring transverse acceleration of the frame in a direction perpendicular to a plane. A control circuit e.g. microcontroller, activates the locking units when the transverse acceleration exceeds a predetermined threshold.

Abstract

The invention discloses a front wheel tilt-preventing front suspension and steering system for bicycles and motorcycles, wherein a frame is provided with two front wheels and a back wheel, the front wheels are provided with planar ground surfaces, a double-shaft hub is provided with a wheel shaft for supporting the two front wheels, a tilting bearing is arranged under the wheel shaft, a steering arm is provided with a tilting shaft, when the steering arm tilts, the tilting shaft can rotate in a titling shaft core, and the steering arm is connected to the frame through a pair of wishbones. During a turn, the steering arm, the frame and the back wheel tilts towards the turning side so as to keep the gravity center at the turning side to balance the centrifugal force, but the front wheels and the double-shaft hub do not tilt, so the turning is comparatively smooth and safe.

Abstract

In accordance with the present invention a vehicle comprises a tilting section and a hanging section both connected to each other. When the vehicle is stationary or traveling straight, gravity will pull the hanging section downwards which will stabilize and keep the tilting section upright. When the vehicle is turning, centrifugal force will swing the hanging section outward and tilt the tilting section inside the turn.

Abstract

A three wheeled car comprises a rigid tiltable assembly containing a driver's cockpit 13 and a tyre 12 which is driven by a power unit contained within rear section 10. The whole assembly is rotatably attached to a conventional front section 15 by rotatable assembly 16. Backwards and forwards movement of foot pedals on device 17, is translated into clockwise or anti-clockwise tilting of the tiltable assembly by rotatable assembly 16 which contains freely rotating bearings, attaches cockpit 13 to front section 15, rotates cockpit 13 in relation to front section 15 and contains a chamber for inter-connection of controls and services. Non-tilting controls are operated from handlebar 18. The tilting action steers the car in the direction of tilt and is self-centering. Tilting is controlled by the hands in alternative embodiments.; Various power, transmission, braking and suspension units can be provided in rear section 10.

Abstract

In a curve-leaning vehicle whose vehicle body is leaning inwardly when the vehicle is negotiating a curve, the vehicle body is supported on an axle frame for pivoting about a longitudinal vehicle body axis. The axle frame has wheels which are independently supported by springs and includes an actuator for tilting the vehicle body inwardly when the vehicle is negotiating a curve. The actuator is operatively connected to the spring support structure for controlling spring forces such that the axle frame remains essentially level when the vehicle is negotiating a curve.

Abstract

A three-wheeled vehicle is disclosed having two front wheels connected by means of an axle and a single powered rear wheel centered between the two front wheels. A steering column is connected to a frame which supports the engine and the rider, and the lower end of the steering column is pivotally connected to the front axle assembly. Foot pedals are provided on either side of the engine frame--one is for acceleration and the other is for braking. Both foot pedals are attached to a support which is connected to the front axle assembly. The bottom of the engine frame is pivotally connected to a yoke at a location rearward of the front wheels. A power-actuated mechanism banks the steering column and engine frame about an inclined bank axis when the vehicle is turned to enhance the stability of the vehicle and the comfort of the rider.
