A parking brake apparatus for a vehicle includes a pair of pressing units receiving power from a driving unit, and pressing a brake pad; a load transmission unit installed between the pair of pressing units, connected to each of the pair of pressing units, and transmitting a pressing load of any one of the pair of pressing units to the other pressing unit; and a load transmission unit restraint unit selectively restraining driving of the load transmission unit.

A parking brake apparatus for a vehicle includes a driving unit including a plurality of motor sections; a pair of pressing units receiving power from the driving unit and pressing a brake pad; and a load transmission unit installed between the pair of pressing units, connected to each of the pair of pressing units, and transmitting a pressing load of any one of the pair of pressing units to the other pressing unit.

A parking brake apparatus for a vehicle including a motor section receiving electric power from an outside, and generating power; a power transmission section rotated by driving the motor section, and including transmission worm gears; a pair of pressing units receiving power from the power transmission section and pressing a brake pad; and a load transmission unit installed between the pair of pressing units, connected to each of the pair of pressing units, and transmitting a pressing load of any one of the pair of pressing units to the other pressing unit.

A parking brake apparatus for a vehicle includes a motor section receiving electric power from an outside, and generating power; a power transmission section rotated by driving the motor section; a pair of pressing units having rotation axes that are disposed parallel to a rotation axis of the power transmission section, and pressing a brake pad by receiving power from the power transmission section; and a load transmission unit installed between the pair of pressing units, connected to each of the pair of pressing units, and transmitting a pressing load of any one of the pair of pressing units to the other pressing unit.

An electrically actuated parking brake has a single electric motor producing a torque, a first torque limiting device with a first spring force, and a second torque limiting device with a second spring force. The first torque limiting device fully transmits a first portion of the torque to a first spindle until a first clamp force overcomes the first spring force and the second torque limiting device fully transmits a second portion of the torque to a second spindle until a second clamp force overcomes the second spring force. When the first clamp force overcomes the first spring force and the second spring force overcomes the second clamp force, the first portion of the torque that exceeds the first spring force is transmitted to the second spindle by the second torque limiting device.

A disc brake (1) for vehicles, in particular for commercial vehicles, includes a brake disc, at least two brake linings (3, 3a), and an adjusting spindle (4) axially adjustable toward the brake linings (3, 3a) for setting an air play (L) between the brake linings (3, 3a) and the brake disc (2). The adjusting spindle (4) has a pressure plate (4a) on a side facing the brake linings (3, 3a), and a pressure piece (9) arranged on the adjusting spindle (4) on a side axially opposite from the brake linings (3, 3a). The pressure piece (9) has an anti-rotation safeguard (10; 10a) for blocking a rotation (R) of the adjusting spindle (4), and the anti-rotation safeguard (10; 10a) axially engages the adjusting spindle (4).

A cast iron brake caliper of a disc brake, includes a caliper back and caliper head connected to the caliper back via tension struts arranged parallel and spaced apart from one another. The caliper head has a housing surrounding an accommodation chamber for functional parts and, separate from and adjacent to the housing, an integrally molded, protruding connector, which accommodates a bearing bore for a fixed bearing, and is connected to the housing by way of an integrally molded rib. The brake caliper is designed such that the rib is guided across the connector up to and into an outer edge region of the caliper head.

A sensor device for detecting brake pad and brake disc wear of a disc brake, in particular for a motor vehicle, includes a sensor device and a transmission unit. The sensor device has at least one transducer and at least one sensor transmission having at least one transmission input and is connected to a transducer. The transmission unit is connected to the transmission input and is designed to be connected to a threaded spindle of the disc brake to be associated therewith in order to transmit a wear-related rotary movement. The transmission unit has a drive sleeve for co-rotational connection to the threaded spindle, an output sleeve which is connected to the drive sleeve, at least one spring element and a driver for co-rotational connection to the transmission input, which is connected to the output sleeve for co-rotation therewith. A disc brake includes such a sensor device.

A disc brake for a vehicle, particularly for a commercial vehicle, includes a brake caliper which straddles a brake disc and in which an application device is arranged, a single-piece rotary lever which has an eccentric element, and at least one brake plunger which is designed as a power screw arrangement having a rotational axis and with which, when the rotary lever is actuated, at least one brake pad can be pressed against the brake disc. The rotary lever is arranged in the brake caliper such that it can pivot relative thereto, and is supported directly or by way of one or more elements connected therebetween, on said brake caliper, in at least one support region. The rotary lever, which can pivot relative to the brake plunger, has at least one convexly-formed section on the side thereof that lies opposite the support point on the brake caliper, and this section lies against a matching concave end face in the axial extension of the rotational axis of said power screw arrangement.
