摘要： A brake assembly comprises: a brake piston configured to be movable for a brake apply or release and having an inner wall forming a piston cavity, wherein a groove is formed on the inner wall of the brake piston; a linearly movable structure positioned within the piston cavity of the brake piston and configured to be linearly movable within the piston cavity; and a resilient material, wherein a part of the resilient material is located within the groove formed on the inner wall of the brake piston and the other part of the resilient material is disposed on an outer surface of the linearly movable structure so that the resilient material is engageable with a surface of the groove formed on the inner wall of the brake piston to move the brake piston by restoring force of the resilient material in response to linear movement of the linearly movable structure.

摘要： The invention proposes a disc brake having a brake caliper (1) and a tensioning device arranged therein for applying force to the brake linings of the disc brake, wherein part of the tensioning device is a brake lever (10) which can be actuated by a force element and preferably by a compressed air cylinder. The brake lever is composed of a lever arm (14), against which the force element is supported, and a brake application shaft (15), which is supported against a pressure piece (8) acting towards the brake linings, and is also supported from the inside against the brake caliper, wherein the brake caliper (1) and the brake application shaft (15) face each other and are formed as shells (21, 22) in which a supporting roller (20) with a roller axis (A) running transverse to the tensioning direction (Z) is mounted. To keep the mutual movability of the parts involved low by the simplest measures possible and without the need for additional parts, the supporting roller (20) is supported with the lateral surface (20A) thereof directly in one of the two shells (21, 22) and is designed to be non-rotatable or have only limited rotational movement with respect to this shell. The supporting roller (20) also serves as a means to centre the brake lever (10) laterally in the brake caliper. A supporting roller particularly suited to these purposes is also to be created.

摘要： A vehicle steering system comprises: a motor assembly operably coupled to a steering rack, the motor assembly comprising a motor having a rotor and a motor position sensor configured to sense a rotor angle of the motor in a single-turn range; and a rotary-to-linear conversion mechanism operably coupled between the motor assembly and the steering rack, the rotary-to-linear conversion mechanism comprising a rotor operably coupled to the rotor of the motor. A processor calculates an absolute angular position of the pinion in a full-turn range of rotation of the pinion based on the sensed rotor angle of the motor and a pinion angle sensed by a pinion angle sensor in a single-turn range, or based on the sensed rotor angle of the motor and an angle of the rotor of the rotary-to-linear conversion mechanism sensed by an angular position sensor in the single-turn range.

摘要： A structure of a rotation locking device that is easily configured and capable of keeping cost down is achieved.
A rotation locking device 4 switches between a first mode where an engaging claw portion 14 engages with an engaging concave portion 9 by an output member 13 rotating an engaging member 8 due to an input member 12 being rotationally driven by an actuator 7, and rotation of a locking gear 5 supported by and fixed to an output shaft 3 of an automatic transmission 2 is restricted, and a second mode where engagement between the engaging claw portion 14 and the engaging concave portion 9 is released and rotation of the locking gear 5 is allowed.
