A power transmission unit of a single-acting plunger type includes a ball screw, a ball nut driven by the ball screw, and a plunger piston coupled to the ball nut. A block housing at least partially encloses the plunger piston and the ball screw. A plunger chamber is at least partially defined by the block housing and a face of the plunger piston. The plunger chamber is selectively pressurized by reciprocal motion of the plunger piston with respect to the block housing driven by longitudinal motion of the ball nut. An electric motor selectively drives the ball screw to responsively reciprocate the plunger piston within the plunger chamber. A motor housing at least partially encloses the ball nut, the electric motor, and the plunger piston. The motor housing includes a block lip which is crimped to the block housing to maintain the motor housing in relation to the block housing.

A parking valve for manually actuating a spring-loaded parking brake, includes: a housing with a port that can be fluidically connected to a release chamber of a spring-loaded brake cylinder, a port that can be fluidically connected to a brake supply reservoir, and a ventilation port; a slide for manual actuation and which can be moved along a full section between two end positions inside the housing. The slide assumes positions along the full section, in which, as a result of at least one seal, there is no fluidic connection between the port to the release chamber and the ventilation port, and assumes other positions along the full section, in which, as a result of the at least one seal, there is no fluidic connection between the port of the release chamber and the port to the brake supply reservoir. A blocking device acts on the slide during movement at least along a partial section of the full section in at least one direction, with a continuously variable counterforce dependent on the position of the slide on the partial section.

Provided is an electronic parking brake system including: an electronic parking brake provided in at least one of a front wheel and a rear wheel of a vehicle and driven by a motor; and a controller electrically connected to the motor, wherein the controller is configured to determine whether a gear stage of an electronic transmission system (a shift by wire: SBW) is shifted to a neutral position during ignition-off of the vehicle, and upon determining that the gear stage is shifted to the neutral position, release engagement of the electronic parking brake.

A brake operation portion that allows a manual brake operation is included in a vehicle cabin, the brake operation portion includes a grip portion, and an elbow rest member is provided at, in the vehicle rear side of the grip portion, a position on which an elbow of a driver can abut in a state in which the driver grips the grip portion so as to be capable of operating the grip portion. Thus, even a physically disabled driver may freely perform a driving operation and easily manually perform a delicate brake operation.

A pivot bearing of a ball screw of a power brake pressure generator for a hydraulic vehicle braking system is fastened at a hydraulic block with the aid of a sleeve that has an internal circumferential edge, which engages from above with the pivot bearing on a front face facing away from the hydraulic block. The sleeve has a flange that is caulked in an annular step in the hydraulic block.
