A turning device includes: a motor configured to generate a drive force for independently steering a steered wheel; a speed reducer connected to a rotary shaft body of the motor; and an overload protection device configured to block transfer of torque between the motor and the speed reducer in the case where an overload occurs.

A compact power steering system is suitable for small vehicles. A torque sensor on a steering shaft detects operator intention to turn. In response, a motor provides torque to assistance in rotating the steering shaft. A strain wave gear set multiplies the motor torque. A coupler having a torsional isolator links the gearbox output to the steering shaft.

An electric steering column device includes a column housing, and a first shaft, a connection shaft and a second shaft provided in the column housing. The connection shaft is movable in an axial direction of the first shaft and the second shaft and is connected to the first shaft and the second shaft so as to rotate together with the first shaft and the second shaft. The first and second shaft are connected to the connection shaft so that the first shaft always rotates at the same rotation speed and that a rotation speed of the second shaft is varied depending on whether or not the connection shaft moves in the axial direction. The device is capable of securing an optimized steering performance by adjusting steering responsibility of a steering wheel depending on a driving state of the vehicle.

A vehicle steering control method in which steering wheel vibrations are suppressed when a clutch is engaged while turning to suppress a sense of discomfort imparted to the driver. In this method, when transitioning from a steer-by-wire mode under an autonomous driving mode in which a steering clutch, through which a steering wheel and left and right front wheels are mechanically disconnected and connected, is disengaged, to an EPS control mode under a manual driving mode in which the steering clutch is engaged and an assist torque that corresponds to a detected torque from a torque sensor is imparted to the left and right front wheels, the steering clutch is engaged, and the assist torque is limited to a value that corresponds to the detected torque from the torque sensor from when the steering clutch is engaged until a prescribed limitation period has passed.

Provided is a steering controller configured to switch from an interruption state to a transmission state. In a state where power transmission from the steering wheel to steered wheels is interrupted, a maximum value selection processing circuit outputs a maximum value, out of a steered angle and a steering angle, to a limiting reaction force setting processing circuit. When the absolute value of the maximum value has become equal to or larger than a limitation start threshold value, the limiting reaction force setting processing circuit rapidly increases a limiting reaction force. An operation signal generation processing circuit controls a reaction-force motor to achieve a reaction force command value corresponding to the limiting reaction force. When the absolute value of the maximum value has become equal to or larger than an engagement threshold value, a clutch is engaged to transmit reaction force from the steered wheel-side to the steering wheel.

A magnetorheological (MR) fluid clutch apparatus(es) is coupled to the at least one motor to receive torque from the motor, the MR fluid clutch apparatus controllable to transmit a variable amount of torque. A mechanism is between the at least one MR fluid clutch apparatus and the body to convert the torque received from the at least one MR fluid clutch apparatus into a force on the body. Sensor(s) provide information indicative of a state of the body or structure. A controller receives the information indicative of the state of the body or structure and for outputting a signal to control the at least one MR fluid clutch apparatus in exerting a desired force on the body to control movement of the body according to a desired movement behavior.

In a steering gear for a motor vehicle, a bush is pressed into a concentric opening in the worm gear, wherein the steering pinion is inserted into the bush, and wherein the bush is designed to transmit a torque acting from the worm gear onto the bush onto the steering pinion. The disclosure further relates to a method for mounting a steering gear for a motor vehicle.

A dual path agricultural machine including a control system having a number of input sensors, status sensors, and output sensors, and a controller configured to operate the dual path machine in a stability control mode and a selective rear-steer engagement and actuation mode. In the stability control mode, the controller adjusts an actual drive output of the dual path machine according to data received from the input sensors and feedback received from the output sensors so as to reduce a difference between the actual drive output and a desired drive output. In selective rear-steer engagement and actuation mode, the controller engages rear-steer mechanisms with caster wheels of the dual path machine and actuates the caster wheels via the rear-steer mechanisms if a criterion is satisfied. The controller disengages the rear-steer mechanisms from the caster wheels or does not actuate the caster wheels if the criterion is not satisfied.
