Abstract

A three-wheeled motor vehicle with front steering wheel 5 and transversely spaced apart rear driving wheels 6,7 on controllable, with sufficient freedom of oscillation in opposite directions, suspension structure. The driver-operated pedals 22 manually change the geometrical configuration of the rear suspension and incorporate with computer control electromechanical gear motor power-assisted force of the pedals and provide ride-by-wire mode, controlling vehicle in vertical position. When the pedal 22 is depressed, a toothed pawl 17 slides along a bracket shaft 16, which is held in position by a return spring (fig 6, 20) and engages with a toothed plate on a rocker arm (fig 6, 9). The pivotal movement of the rocker arm (9) is transferred to synchronous movements of the swing arms (fig 3, 8) in opposite directions to produce lateral tilt of the vehicle.

I
VEHICLE WITH DIFFERENTIAL SUSPENSION
The present invention relates generally to wheeled vehicles and more particularly to a three-wheeled vehicle having a pair of spaced- apart wheels.
Such vehicles are well-know, but suffer from the disadvantage that distance between pair of spaced-apart wheels should be long enough to compensate the resultant reaction of centrifugal force and inclined road surfaces.
An object of this invention is to provide vehicles with significantly short distance between pair of spaced-apart wheels.
Accordingly, a primary object of the invention is to provide an improved three-wheeled vehicle having a pair of spaced-apart wheels secured to the controllable differential suspension structure. This differential suspension is directly responsible to the balance of the vehicle to a state of equilibrium.
Preferably the drivers cabin is made demountable from the vehicle frame.
The invention will now be described further, by way of example, with reference to the accompanying drawings, in which: FIGURE 1 is a perspective view of the whole three-wheeled vehicle of the invention: FIGURE 2 shows in perspective, the three-wheeled vehicle without driver's cabin and body panels.
FIGURE 3 shows in perspective, the rear differential suspension of the invention.
FIGURE 4 is a diagrammatic rear elevation view of the three-wheeled vehicle showing the rear differential suspension being pivoted to an equilibrium position for traversing a turn.
FIGURE 5 is a diagrammatic rear elevation view of the vehicle in a vertically inclined equilibrium state.
FIGUTE 6 is a exploded view of the rocker arm components arrangement.
FIGURE 7 is a exploded view of the swing arm components arrangement.
The wheeled vehicle of the present invention as show best in FIg.2 having a single front wheel 5 which is mounted on telescopic fork structures 4 and pivotally connected to the vehicle frame 21.
The front part of the vehicle is similar to a conventional motorcycle and responsive to pivotal steering movement of the handlebar 3.
Under the operators seat 2 is disposed the engine, transmission and differential assembly 29.
Between the controlling position of the differential suspension pedals 22 is disposed the differential lock handle 23.
The rear part of the vehicle having a pair spaced-apart wheels 6 and 7 between which are disposed exhaust silencer 30 and fuel tank 31.
Rear wheel with brake disc 32 are secured to wheel shaft 33 which is held in place by two bearings 34 and attached to the end of the swing arm 8 with brake caliper 43.
Wheel shaft 33 is jointed to the hub 38 by retaining nut 45. The sprocket 39 is attached to the hub 38 by nuts 40 as shown in Fig.7.
Vehicle is beft-driven 41 from an output sprocket on each side of the engine, transmission and differential assembly 29. The drivebett 41 is pulled by tensioner 42.
Other end of swing arm 8 held in place by two bearings 37 and secured by retaining nut 44 to stub axle 35 on the vehicle frame 21.
The rocker arm 9 held in place by two bearings 27 is pivotally connected to stub axle on the vehicle frame 21 and secured by retaining nut 28. Each end of the rocker arm 9 is connected with suspension strut assembly 11 by balljoint assembly 12 and secured by retaining nut 36 as shown in Fig.6.
Therefore, when a pair spaced-apart rear wheels are mounted on differential suspension structure they make free synchronous pivotal movement in opposite directions as shown best in Fig.3.
The pedals 22 are controlled the configuration of differential suspension. When the pedal 22 is depressed, the first movement is released the puffs of the tension spring 18 by means of the cable 26 on guide gear 19. Then the toothed pawl 17 is slide along the bracket shaft 16 which is held in position by return spring 20 and engage with the toothed plate on the rocker arm 9. The movement of pedals are transmitted generated forces to pivotal movement of the rocker arm 9. The pivotal movements of the rocker arm 9 is transferred to synchronous pivotal movements of the swing arms 8 in opposite directions. This movement is controlled inclination of the vehicle to a position of equilibrium.
When the powered vehicle is moved with relatively high speed the configuration of differential suspension is change, as caused by external forces, centrifugal force or inclination of the road surfaces. The differential suspension is automatically self-pivoted on vehicle frame 21 and proportionally differentiated these forces between wheels 6 and 7 to one place on stub axle 25.The steenng movement of the handlebar 3 is responsive for maintaining the balance of the vehicle to a state of equilibrium as shown in Fig.4.
Namely that the resultant of all forces is directed through the center of gravity of the vehicle and point of contact of the vehicle wheels with the ground.
When speed of the vehicle is significantly decreased the balance of the vehicle to state of equilibrium generally depend on mechanism of controlling configuration the differential suspension by means of the pedals 22 as shown in Fig.5.
The automatically controlled inclination of the vehicle mechanism 15 is incorporated with toothed plate 10 for automatically adjustment of the differential suspension configuration to a position of equilibnum of the vehicle.
When the vehicle is stopped, depressing the differential lock lever 23 the cable 24 operated caliper 14 biting on a plate 10 preventing the vehicle from leaning.
Only one out of many solution in the art is made this vehicle with demountable driver's cabin I as shown on Fig.1.
