摘要： A steer-by-wire steering system is proposed, having a steering wheel actuator and a braking device that acts on the steering column (3). The braking device is activated when the vehicle steering wheel is to be blocked or at least sharply braked, such as when the steering stop is reached or a wheel goes over the edge of a curb. The braking device functions like a switchable freewheel.

摘要： The present invention provides a system for generating an end of travel feedback to the driver of a vehicle where the vehicle includes a steer by wire system. The system includes a steering wheel, a steering shaft, a motor, and a clutch. The steering wheel is configured to control the steer by wire system. The steering shaft is coupled to the steering wheel and rotates in conjunction with the steering wheel. To provide road feel resistance to the driver, the motor is coupled to the steering shaft. Further, the clutch is configured to mechanically couple the steering shaft to the road wheel to provide mechanical resistance when the road wheel is at an end of travel position.

摘要： A drive-by wire steering system is provided. The system comprises a steering shaft and a center feel mechanism. The steering shaft is configured for a first angular displacement about a first axis. The steering shaft has a first geared portion and a first end connectable to a vehicle's steering wheel. The center feel mechanism comprises a cam face, an urging member and a second geared portion. The first geared portion and the second geared portion are operatively engaged such that the first angular displacement of the steering shaft imparts a second angular displacement about a second axis to the center feel mechanism. The cam face and the urging member are configured to generate a retuning torque to the center feel mechanism. The retuning torque has a direction opposite the second angular displacement.

摘要： A steering apparatus includes a user-actuable steering-angle input device with an associated steering shaft, a steering-angle setting device coupled nonmechanically to the steering-angle input device and a reaction torque device which is coupled to the steering shaft. The reaction torque device produces a reaction torque mechanically and has at least one element which can be deflected elastically in a linear manner and is coupled to the mechanism by a driver unit acting axle steering shaft. In certain embodiments, a steering-shaft pinion and a rack which is coupled to the latter serves as a piston rod for at least one piston that can be deflected elastically in a linear manner. The at least one piston is guided in axially moveable fashion in a cylinder and, together with the piston rod, forms the driver unit. Alternatively, the mechanism can contain an eccentric disc which is coupled rotatably to the steering shaft and against the outer circumference of which there rests the end of a piston rod of a piston guided in axially moveable fashion in a cylinder.

摘要： A solar tracking system includes a solar array, a support structure configured to support the solar array, a driveshaft coupled to the support structure, a base configured to rotatably support the driveshaft, and an articulation system coupled to the driveshaft and configured to articulate the driveshaft relative to the base. The articulation system includes a gearbox coupled to the driveshaft. The solar tracking system also includes a motor mechanically operably coupled to the gearbox to cause the driveshaft to rotate, and a controller that determines a fault caused by the winding up of the driveshaft, and, in response to determining the fault, shorting the windings of the motor and/or providing power, which is generated by the motor when the unwinding driveshaft drives the rotation of the motor, to a load, such as an energy storage device, a resistive load, and/or a heating element.

摘要： A handwheel actuator for a steering system includes a stator, a shaft, and a rotor. The shaft is disposed within the stator and configured to be rotatably driven by a handwheel. The rotor is rotatably driven by the shaft. The rotor and the stator form a first fluid chamber and a second fluid chamber. Rotation of the rotor is configured to displace from the first chamber to the second chamber so as to apply a rotational resistance to the shaft.
