Abstract
A system for a drive for actuating a parking brake operably involves a brake caliper. The brake caliper has at least one brake piston with a brake piston axis, the piston being actuatable by means of an operably actuating lever with a rotational center. An electric motor is fixed to the brake caliper and mechanically coupled to the actuating lever with the output shaft that exits the electric motor.
Claims30
A drive, for actuating a parking brake in a brake caliper, said drive comprising:
- at least one brake caliper, further comprising:
- at least one brake piston operable along a brake piston axis positioned on an actuation side;
- and
- an electromotor having an output shaft providing motive rotational force fixably secured with said brake caliper;
- said brake piston operably engaging an actuation lever having a respective center of rotation;
- said output shaft being operably coupled to said actuation lever, whereby operating said actuation lever operates said brake piston;
- said actuation lever operating said brake piston;
- said electromotor comprising a worm element on said output shaft;
- said worm element operably coupled to said brake piston during a use thereof;
- said output shaft and said worm element rotating cooperatively during a use of said drive along a worm-spindle transmission;
- said worm-spindle transmission having a spindle;
- and
- said spindle operably coupled to said actuation lever during said use.
