Abstract
An actuating device may include an energy recovery unit for a mechanical brake system. The actuating device may have an actuating drive for a brake application movement of a brake part for a service brake function. The actuating device has a force cartridge with a prestressed spring and with a ramp bearing as the energy recovery unit The ramp bearing may be fastened to the actuating drive on one side and to the spring on the other side. The force cartridge is fitted on a line of force action of the actuating drive and interacts with the actuating drive such that a force component for assisting the actuating drive is provided in a manner dependent on an adjustment position of the actuating drive.
Claims20
An actuating device comprising:
- an energy recovery unit for a mechanical brake system;
- an actuating drive for a brake application movement of a brake part for a service brake function;
- and
- a force cartridge with a prestressed spring and with a ramp bearing as the energy recovery unit, wherein the ramp bearing is fastened to the actuating drive on a first side and to the prestressed spring on a second side, wherein the force cartridge is fitted on a line of force action of the actuating drive and is configured to interact with the actuating drive such that a force component for assisting the actuating drive is provided based on an adjustment position of the actuating drive;
- wherein the ramp bearing is a first ramp bearing, the actuating device comprising a second ramp bearing for the brake application movement, wherein the second ramp bearing includes a cam track with a linear region and with a non-linear region;
- wherein the first ramp bearing includes a first region and a second region that correspond with the second ramp bearing over a 1 angle of rotation;
- wherein the first region has a zero gradient for a neutral behavior while overcoming an air gap, wherein the second region has a non-linear characteristic that is coordinated such that a bistable situation can be generated over an entire range of a braking intervention.
An actuating device comprising:
- an energy recovery unit for a mechanical brake system;
- an actuating drive for a brake application movement of a brake part for a service brake function;
- and
- a force cartridge with a prestressed spring and with a ramp bearing as the energy recovery unit, wherein the ramp bearing is fastened to the actuating drive on a first side and to the prestressed spring on a second side, wherein the force cartridge is fitted on a line of force action of the actuating drive and is configured to interact with the actuating drive such that a force component for assisting the actuating drive is provided based on an adjustment position of the actuating drive;
- wherein the actuating drive is a first actuating drive, the actuating device comprising a second actuating drive, wherein the first and second actuating drives are configured to perform brake application movements independently of one another.
An actuating device comprising:
- an energy recovery unit for a mechanical brake system;
