  • HYDRAULIC BLOCK FOR A HYDRAULIC POWER UNIT OF A HYDRAULIC POWER VEHICLE BRAKING SYSTEM
    Publication number: 20210309197
    Abstract: A cuboidal hydraulic block of a hydraulic power unit of a hydraulic power vehicle braking system for use in a left-hand drive vehicle or a right-hand drive vehicle to be attachable, rotatably by 180° about a horizontal axis, at a splashboard of a motor vehicle. An electric motor of a power brake pressure generator is thus selectively situated on a right or a left side of the hydraulic block.

  • FASTENING OF A COVER TO A HOUSING
    Publication number: 20210254713
    Abstract: A cup-shaped cover of a pedal travel simulator, hydraulic accumulator, or a damper chamber, using a radially resilient connecting ring, which protrudes into a groove of the cover and into an opposing groove of a receptacle of a hydraulic block of a traction slip controller of a hydraulic vehicle braking system, to fasten inseparably at the hydraulic block.

  • HYDRAULIC POWER UNIT FOR A HYDRAULIC VEHICLE BRAKING SYSTEM
    Publication number: 20210206363
    Abstract: A piston of a hydraulic power unit of a hydraulic power vehicle braking system including slip control is guided directly, without a cylinder liner, in a cylinder bore of a hydraulic block. The piston is rotatably fixedly and axially displaceably held in a bushing with the aid of an anti-rotation mechanism, which in turn is rotatably fixed at the hydraulic block. A pivot bearing of a worm gear for displacing the piston is fixed at the bushing.

  • HYDRAULIC BLOCK FOR A HYDRAULIC UNIT FOR A HYDRAULIC VEHICLE BRAKING SYSTEM
    Publication number: 20210129816
    Abstract: A hydraulic block for a hydraulic unit of a slip-controlled, hydraulic power vehicle braking system including a primary piston, which protrudes from the hydraulic block and at which a pin-shaped signal generator holder for a permanent magnet is situated. The primary piston and the signal generator holder are enclosed with a tubular housing the shape of a cylindrical bowl, at which abut two converging, tangential walls.

  • MASTER BRAKE CYLINDER FOR A HYDRAULIC VEHICLE BRAKE SYSTEM
    Publication number: 20210086730
    Abstract: A hydraulic block of a slip regulation system of a hydraulic external force vehicle brake system that has a master brake cylinder bore and forms a master brake cylinder. In order to prevent a hard impact of a master brake cylinder piston on an end stop when the master brake cylinder is released, in particular when there is a sudden release, for example when the driver's foot slips off the brake pedal, the present invention provides a hydraulic return flow damper that is integrated in the master brake cylinder piston.

  • Master brake cylinder for a hydraulic vehicle brake system
    Patent number: 10668910
    Abstract: A hydraulic block of a slip regulation of a hydraulic vehicle power brake system that has a master brake cylinder bore and forms a master brake cylinder. In order to prevent a hard impact of a piston of the master brake cylinder against an end stop when the master brake cylinder is released, in particular when there is an abrupt release, for example when the foot slides off a foot brake pedal, a hydraulic return damper that is integrated in the piston is provided.

  • Pedal travel simulator and hydraulic block including a pedal travel simulator
    Patent number: 10507812
    Abstract: A pedal travel simulator for a hydraulic vehicle power braking system with a cup-shaped cylinder cover in which a piston spring is accommodated, which is held by an orifice disk as a stop for a piston of the pedal travel simulator in the cylinder cover. Recesses are provided in an outer edge of the orifice disk, through which the piston is able to displace brake fluid on its rear side out of a cylinder of the pedal travel simulator through a circumferential groove into a return.
