Abstract

The necessity to get higher degrees of safety through better stabilities of the "Scooter-Cyclemotor- Bicycle-Motorcycle" has made theese 2 kinds of assemblies (front and rear) . The Front assembly always has forwarding the" 2 steering, inclining, shock-absorbing, braking, parallel front wheels" and with the already existent 1 rear-wheel in the rear side, or with the Rear-assembly, that has the"2 inclining, shock-absorbing, braking, parallel rear-wheels" (Page :1 ,2,3,4,5,6,7. / 7) . Those 2 kind of assemblies are singularly, or both, suitable to build a vehicle with' 3, or 4 wheels' (with 2 rear-wheels) , always determining 3 or 4 points of contact on the ground (not only 2 ) . The vehicle with '3, or 4 wheels' is safer, it's more vertical steady and answers the highest degrees safeties either, with a second passenger on board, or with major loads upon (like heavier accumulators use for electtric or hybrid power and/or if it uses major load-structures like new body carriage) . The vehicle is always safe especially when adverse metheo-conditions happen (stormy weather, snowing, hailing etc.) , or in specific unbalanced conditions (like in up or down dangerous pending roads "in uphill or downhill") . Then the Front-assembly with, or w/o the Rear-assembly offers the following advantages in : .A) STAND UP STABILITY in ' parking mode' .B) STAND UP STABILITY in ' marching and in turning mode' (without or with braking) .C) AGILITY inside SECURITY either in th urban traffic or in highways. .D) GOOD ROADABILITY.

Abstract

A form of vehicular suspension which duplicates the dynamic properities of a motor/pedal bikers suspension and which is also capable of keeping the vehicle upright when it is moving slowly or is stationary is achieved by having at least one pair of wheels 3 laterally disposed about the vehicle's body 4 in conjunction with a mechanism connecting the wheel's uprights and the body in such a manor as to allow them to rotate freely and in unison about the wheel's contact points with the ground. Thus the machine may be banked into corners like a bike. The vehicle's angle of lean is controlled by use of wheel gyroscopic forces. At low speed and when stationary the mechanism is locked in rotation relative to the body and thus the vehicle becomes in effect a narrow car.; As the rider/driver does not have to be able to touch the ground with his feet to stabilise the vehicle, it may be fully enclosed, and therefore has the potential to be as safe as car.

Abstract

Three or four wheeled vehicle which leans into corners so as to remain stable even when the vehicle has a narrow track. The steering mechanism is such that leaning of the vehicle to either respective side of the vertical causes the front steering wheels (10) to turn in the same steering direction, e.g. a lean to the left causes an anticlockwise, when viewed from above, turning of the front wheels (10). The front wheels (10) can be supported on a parallelogram linkage system (17, 18) so that the steering axis (16) of the wheels (10) remain parallel with the vehicle body as the vehicle leans.; Steering can be controlled through a steering wheel (14) which, disregarding the influence of body lean, turns the front wheels (10) in a steering direction relative to the turn of the steering wheel which is opposite in sense, e.g. an anticlockwise turn of the steering wheel (14) produces a clockwise turn, when viewed from above, of the front wheels (10). In order to produce a predetermined steering characteristic the ratio between the angle of lean of the vehicle and the responsive angle of turn of the front wheels (10) varies with the forward velocity of the vehicle.
