The mechanically operated structure of the steering centering/damping mechanism also provides a positive steering centering force that increases in intensity as the steer angle of the axle/suspension system increases.

Abstract: A steering system for a towable implement includes a steering sensor, an implement steering controller, a steering control valve, a steering cylinder, and an implement steering mechanism that steers the implement. The steering sensor measures, directly or indirectly, the angular position of the steerable wheels of the implement. The implement steering controller processes feedback from the steering sensor and with a desired steering angle, outputs a steering control signal that is input to the steering control valve. The steering control valve controls the flow of hydraulic fluid to the steering cylinder, which, in turn, powers the implement steering mechanism to turn the wheels of the implement. The steering system may be operated in various control modes, such as, a transportation steering mode, a corner and 180 turn steering mode, a swath tracking steering mode, crab steering mode, and a manual steering mode, which allows manual control of the steering system.

Abstract: When a motor vehicle is steered, as turning reaction forces from the road surface, for example, rearward radial loads are applied from rear wheels to corresponding end portions of a steered shaft via corresponding knuckles and corresponding tie rods. A motor vehicle steering system includes first and second counter load application mechanisms that apply counter loads against the radial loads to the corresponding end portions of the steered shaft. Each of the counter load application mechanisms includes a motion conversion mechanism that converts torsional motion of the corresponding end portion of an axle beam caused by a ground contact reaction force of the corresponding rear wheel via the corresponding knuckle and a corresponding king pin into, for example, forward motion of the corresponding end portion of the steered shaft.

The steer return device, steer lock and biasing device can be positioned at a same opposite end of the king pin. Another suspension system can include a king pin, and a steering knuckle assembly including a steer return device which encircles the king pin. The steering knuckle assembly can be rotated relative to the king pin, without axial displacement relative to the king pin, by a biasing force which results from deformation of a biasing device by the steer return device.

Abstract: In a vehicle steering device, extendable portions whose elastic properties corresponding to a force acting in a compressing direction and whose elastic properties corresponding to a force acting in a stretching direction are asymmetrical are disposed in a symmetric fashion at intermediate sections of tie rods. Thus, an effective steering gear ratio with respect to leftward and rightward steering can be properly changed in accordance with a vehicle speed by using a simple configuration that does not use a complex mechanism having a motor. In this case, a steering gear ratio can be mainly changed for one of the wheels, while a linear lateral force corresponding to steering can be generated at the other wheel. Moreover, since the steering gear ratio can be changed mechanically without performing motor control, the occurrence of control delay can be prevented, thereby reliably preventing deterioration of the driver's operational feel.

When the stabilizer is extended from the equilibrium configuration, the gas spring is activated to responsively and automatically return the stabilizer to the equilibrium configuration; and when the device is compressed from the equilibrium configuration, the gas spring is activated to responsively and automatically return the stabilizer to the equilibrium configuration.

Furthermore, the damping effect may be adjusted through a damping coefficient. High damping coefficients may correspond to stronger damping effects. During periods associated with a greater influence of torque steer, the damper may be configured with a high damping coefficient to counteract torque steer.

Abstract: The invention is a panhard bar that can alter the tracking offset while the car is in motion, and allow the driver of the car the ability to change the tracking as the driver desires, thus improving the turning ability of the car as the track condition changes. The present invention mechanically lengthens or shortens the panhard bar thus moving the axle to the left or right. This then changes the tracking of the front to rear wheels. Adjusting means are placed in reach of the driver to accomplish the change. In another embodiment the adjustment means is not controlled by the driver, but rather by a characteristic reaction of the car. The adjustments means may respond to the front wheels turning to the left or right, to deceleration forces indicating a turn on the track is approaching, and to acceleration forces indicating the straightaway of the track is approaching.
