Estimating the term…
A hydraulic vehicle brake equipped with a parking brake device, in particular for motor vehicles, including a brake housing in which a hydraulic service pressure chamber is delimited by a brake piston, wherein the parking brake device acts on the brake piston and, in the applied condition, can be locked by a locking device, and an energy accumulator cooperating with the brake piston is equipped with at least one integrated spring element. In order to realize a simple and low-cost parking brake function that complies with legal requirements, according to the invention, the parking brake device is operable by a pressure that is introduced into the service pressure chamber and enables charging the energy accumulator.
A hydraulic vehicle brake equipped with a parking brake device, in particular for motor vehicles, including a brake housing in which a hydraulic service pressure chamber is delimited by a brake piston, with the parking brake device acting on the brake piston and, in the applied condition, being lockable by means of a locking device, and an energy accumulator cooperating with the brake piston being equipped with at least one integrated spring element, wherein the parking brake device is operable by a pressure that is introduced into the service pressure chamber and enables charging the energy accumulator, and wherein an arresting unit, formed of at least one electromagnet with a coil that fulfils the function of a sensor for sensing the position of a slide actuated by an armature of the electromagnet, is provided which maintains the energy accumulator in its charged condition during service brake operations.
