Abstract
The present invention relates to a system, comprising a transmission unit being arranged for converting a rotational motion into a translational motion, the transmission unit including an input and an output, wherein the input is configured to receive torque from a motor and the output is configured to provide a brake force for pressing a brake pad against a friction surface; a housing defining a hydraulic pressure chamber, wherein the housing at least partially encompasses the transmission unit; and an axially movable piston arranged in the housing and coupled to the transmission unit such that a translational motion of the piston causes a translational motion of the transmission unit for providing the brake force in a hydraulic operation mode.
Claims11
A system, comprising
- a transmission unit being arranged for converting a rotational motion into a translational motion, the transmission unit including an input and an output, wherein the input is configured to receive torque from a motor and the output is configured to provide a brake force for pressing a brake pad against a friction surface;
- a housing defining a hydraulic pressure chamber, wherein the housing at least partially encompasses the transmission unit;
- and
- an axially movable piston arranged in the housing and coupled to the transmission unit such that a translational motion of the piston causes a translational motion of the transmission unit for providing the brake force in a hydraulic fall-back mode;
- and
- a roller bearing disposed between the input and the piston, wherein the bearing is configured to enable a rotating movement of the transmission's input relative to the piston,
- wherein at least the output of the transmission unit is axially disposed between the piston and the brake pad and is disposed to press the brake pad directly,
- wherein the input of the transmission unit is disposed to entirely pass through the piston and the hydraulic pressure chamber, and
- wherein the piston comprises a receiving section in which the input of the transmission unit is received.
A system, comprising
- a motor including an output shaft;
- a transmission unit being arranged for converting a rotational motion into a translational motion, the transmission unit including an input coupled to the output shaft and an output, wherein the input is configured to receive torque from the motor and slidably arranged with respect to the output shaft and the output is configured to provide a brake force for pressing a brake pad against a friction surface;
- a housing defining a hydraulic pressure chamber, wherein the housing at least partially encompasses the transmission unit;
- an axially movable piston arranged in the housing and moved by pressurized brake fluid filled in the hydraulic pressure chamber, wherein the piston encompassed at least a part of the input of the transmission unit such that a translational motion of the piston causes a translational motion of the input and the output for providing the brake force in a hydraulic operation mode;
- and
- a roller bearing disposed between the input and the piston, wherein the bearing is configured to enable a rotating movement of the transmission's input relative to the piston,
- wherein at least the output of the transmission unit is axially disposed between the piston and the brake pad and is disposed to press the brake pad directly,
- wherein the input of the transmission unit is disposed to entirely pass through the piston and the hydraulic pressure chamber, and
- wherein the piston comprises a receiving section in which the input of the transmission unit is received.
