Hydraulic actuator for actuating retainer brake lining of fixed caliper brake of e.g. commercial vehicle, has pistons magnetically influenced, where movements of pistons are additionally electromagnetically controllable
Hydraulic actuator for actuating retainer brake lining of fixed caliper brake of e.g. commercial vehicle, has pistons magnetically influenced, where movements of pistons are additionally electromagnetically controllable
The actuator (10) has one or multiple pistons (11) acted upon with hydraulic fluid (14). The pistons are formed for pressing a brake lining (13) with respect to a brake disk (2) when the pistons are acted upon with the hydraulic fluid, where the brake disk is arranged in a retainer (12) for the brake lining. The pistons are magnetically influenced and movements of the pistons are additionally electromagnetically controllable. Each piston is surrounded by a coil (5), which is formed for producing a magnetic field. An independent claim is also included for a fixed caliper brake.
