A wheel support or a pivot bearing of a vehicle includes a receiving molding for a ball-joint pin of a track rod for changing the toe angle of a wheel rotatably secured to the wheel support or pivot bearing. The receiving molding is provided with an elastomer layer which lies at least partly in a force transmission path from the ball-joint pin to the wheel support or pivot bearing. The elasticity or possible elastic deformability of the elastomer layer is lower in the receiving molding sections via which a greater force component is transmitted, in particular in the range of smaller track angles, when the track rod is moved in order to steer the wheel than in receiving molding sections via which a smaller force component or no force component is transmitted when the track rod is moved in order to steer the wheel.

A wheel steering system is provided that improves an environment of an actuator being mounted and reduces changes in toe angles of wheels at the time of a suspension stroke. The system includes: right and left hub carriers supported by a rear suspension mechanism; right and left tie rods having outer ends in a vehicle width direction thereof pivotally connected to the right and left hub carriers; and a Watts link having inner ends in the vehicle width direction of the right and left tie rod pivotally attached thereto so as to be pivotable about a pivot axis, wherein the actuator and the Watts link are arranged above springs, and the Watts link is connected with the actuator so as to be displaceable substantially along the vehicle width direction when a driving force of the actuator is inputted to the Watts link.

A wheel steering system includes: a rear suspension mechanism inclusive of a knuckle member for rotatably holding a right rear wheel; a first cam and a second cam that are rotatably supported; a first cam follower 18 that follows the first cam; a second cam follower 20 that follows the second cam 16; cam grooves 48 respectively provided in the first and second cams; a first engaging pin and a second engaging pin that engage with the respective cam grooves; and a rotational driving force transmitter that transmits a rotational driving force of an electric motor to the first and second cams, wherein the first cam and the first cam follower are arranged on a front side in the vehicle front-rear direction of an axle, and the second cam and the second cam follower are arranged on a rear side in the vehicle front-rear direction of the axle.

A control method in a motor grader including a running wheel, an inclination mechanism which inclines the running wheel, an operation portion, and a sensor capable of detecting whether or not the running wheel is at an erect position includes outputting from a controller, a control signal for driving the inclination mechanism in response to an operation command in accordance with a state of operation onto the operation portion and stopping output of the control signal in response to the operation command when the sensor detects the erect position.

A vehicle of the present disclosure may include at least one pair of opposing wheels coupled to a tiltable central chassis by a four-bar linkage or the like, such that the wheels are configured to tilt in unison with the central chassis. A steering actuator and/or a tilting actuator may be discretely controllable by an electronic controller of the vehicle. The controller may include processing logic configured to maintain alignment between a median plane of the chassis and a net force vector caused by gravity and any induced centrifugal forces. Various control algorithms may be utilized to steer the vehicle along a desired path, either autonomously or semi-autonomously.

A wheel suspension includes an axle limb which supports a wheel. The axle limb includes a first steering axle which provides a first steering angle in a specified range for the wheel, and components for connecting the axle limb to a support structure. At least one of the components includes a second steering axle which provides a second steering angle which is different than the first steering angle provided by the first steering axle. The second steering axle is selectively releasable. The components for connecting the axle limb to the support structure form a double transverse link axle which includes an upper traverse link and a lower traverse link. A support tube is arranged at a chassis-side end portion of each of the upper traverse link and the lower traverse link of the double transverse link axle. The support tube is pivotable about the second steering axle.

An amphibious multi-terrain water planing vehicle including: a. a hull having a top, a bottom, a front end, a rear end, a first side and a second side; b. at least one track frame, in exemplary embodiments a pair of track frames, mounted to the hull; c. a sole propulsion and water planing device including at least one continuous rotatable track having an outside surface and an inside surface, in exemplary embodiments a pair of continuous rotatable tracks, mounted to the at least one track frame, in exemplary embodiments each of the pair of continuous rotatable tracks mounted to each of the pair of track frames; the at least one continuous rotatable track, in exemplary embodiments the pair of continuous rotatable tracks not vertically adjustable relative to the hull wherein the vehicle when transitioning from land to water and vice versa requiring no modification, and wherein the vehicle is able to plane on water from a stand still position.

A wheel suspension includes an axle limb which supports a wheel. The axle limb includes a first steering axle which provides a first steering angle in a specified range for the wheel, and components for connecting the axle limb to a support structure. At least one of the components includes a second steering axle which is selectively releasable in order to provide a steering angle which is different than the first steering axle. The components for connecting the axle limb to the support structure form a McPherson suspension.

The present invention provides a steering system for an in-wheel motor vehicle capable of controlling driving torques and speeds of in-wheel motors mounted in left and right wheels to be different from each other at the time of curve driving of the vehicle to generate a steering angle of the wheel for the curve driving, and performing a steering angle control of sensing the generated steering angle and fixing the steering angle to a desired steering angle.
