Multiple shaft diameter flexible coupling system

Compression exerted by a clamp collar integral to a molded plastic flexible shaft coupling accommodating angular shaft misalignment upon the circumferential outward surface of a radially compressible molded sleeve insert located in a shaft bore of the flexible coupling facilitates engagement of a reduced diameter shaft located within the sleeve insert. Use of a sleeve insert having a different internal diameter similarly accommodates flexible coupling to another diameter shaft. Utilization of sleeve inserts selected from a plurality of different reduced internal diameters and exterior diameters sized to fit either shaft bore enables flexible coupling of both multiple matched shaft diameters and an exponential number of differing opposed shaft diameter combinations within a range limited by the flexible coupling shaft bores. Radial compressibility of the sleeve insert is facilitated by the utilization of resilient material, interruption of the circumferential extension by a longitudinal slot, or both. Utilization of congruent longitudinally uniform, radially non-uniform, flexible coupling shaft bore and insert sleeve outward surfaces provides additional torque transmission capacity.

Shock absorbing vehicle body structure

A shock absorbing vehicle body structure in a vehicle includes a substantially quadrilateral front subsidiary frame comprised of left and right side members extending in a longitudinal direction of a vehicle body and connected at their front and rear ends to each other by a front cross member and a rear cross member. The front subsidiary frame is supported at its four corners on main frames for the vehicle body through rubber mounts and bolts. Upon full-lap collision of the vehicle, the left rear bolt is first broken, whereby the rear end of the left side member is separated from the main frame and then, the right rear bolt is broken, whereby the rear end of the right side member is separated from the main frame. The right and left side members are formed with different rigidities to a longitudinal load applied thereto, which causes the right and left rear bolts to break at different times, or with a time lag therebetween. Such a time lag decreases the peak value of deceleration of the vehicle at a time when the front subsidiary frame is separated from the main frames due to a full-lap collision of the vehicle.

The first and second rotors are connected via a thread feed mechanism (36; 136) that converts a relative rotation between the first and second rotors into an axial linear movement between the first and second rotors that is used for changing a distance between a vehicle body part and a corresponding end of a suspension spring in a vehicle height adjusting system (9; 109). Owing to a differential rotation of a high gear ratio between the first and second rotors, a significant torque amplification is possible with a compact arrangement. The use of spur gears instead of a worm gear mechanism minimizes torque loss.

Vehicle lean and alignment control system

The amount of lean to be provided is determined by force sensors, the speed, and / or the angle of turn. Then the vehicle is leaned by actuators in the suspension in accordance with a predetermined protocol in an electronic control unit (ECU). The protocol also provides shock absorption by rapidly tracking a contour of a surface on which the vehicle rides. The suspension is provided by a plurality of arm assemblies each including a lower arm, an upper control arm, and an actuator motively connected to the lower arm and to the upper control arm. The arm assemblies are pivotally connected to the frame on a common axis. The arm assemblies generally form parallelograms and are actuated in concert to remain generally parallel to each other through a range of angles to adjust the lean of the vehicle. The arm assemblies are also actuated independently of each other to accommodate variations in the contour. In one aspect, an actuator controlled by an ECU can be replaced by a mechanical actuator that can be activated manually such as by a driver's own leaning weight.

Vehicular rear suspension system

A vehicular rear suspension system includes an upper arm, a lower arm, and a control arm, each of which is connected to a knuckle. A straight line passing through a ball joint and a rubber bushing joint intersects the road surface at an intersection point that is positioned behind a ground contact point of the rear wheel in the longitudinal direction of the vehicle body. The ball joint connects the upper arm to the knuckle, and the rubber bushing joint connects the lower arm to the knuckle. Longitudinal elastic coefficients of the three arms are set in a predetermined relationship. Therefore, the intersection point at which an elastic kingpin intersects the road surface is positioned without fail behind a point of action of a lateral force when turning in the longitudinal direction of the vehicle body to achieve a lateral force toe-in and enhanced steering stability of the vehicle.

Camber angle controlling device

A camber angle applying device is controlled to adjust the camber angle of wheels to a predetermined value. Therefore, the characteristics (or a high gripping property) of a high gripping force and the characteristic (or a low rolling resistance) of a small rolling resistance can be separately used as the performance of the wheels. By utilizing the high gripping property of the wheels, therefore, a vehicle is enabled to reduce its energy consumption, while retaining its running characteristics (such as a turning performance, an accelerating performance or a braking performance), by utilizing the rolling resistance of the wheels. Moreover, the camber angle applying device is controlled to reduce the rolling resistance of the wheels, so that the energy loss to occur in the wheels during running can be reduced to further reduce the energy consumption of the vehicle.
