Abstract
Proposed is a vehicle brake apparatus including a motor unit configured to generate motive power with received external electrical power, a driveline unit provided with a reduction gear unit that is rotated by drive of the motor unit and reduces the motive power of the motor unit and a bearing that supports rotation of the reduction gear unit, a cylinder unit configured to press a brake pad with the motive power received from the driveline unit, a load sensing unit configured to sense a load produced from axial force of the reduction gear unit, and a housing unit connected to the motor unit and having the driveline unit and the load sensing unit installed therein.
Claims4
A vehicle electro-mechanical brake apparatus comprising:
- a motor unit configured to generate motive power when supplied with electrical power;
- a driveline unit including (1) a reduction gear unit including at least one reduction gear configured to be rotated by the motor unit and reduce the motive power of the motor unit, and (2) a bearing configured to support rotation of the reduction gear unit;
- a cylinder unit configured to press a brake pad with the motive power from the driveline unit;
- a load sensing unit configured to sense a load produced from an axial force of the reduction gear unit;
- and
- a housing unit connected to the motor unit and configured to house the driveline unit and the load sensing unit,
- wherein:
- the at least one reduction gear includes a shaft connected to the cylinder unit and configured to contact the load sensing unit, wherein the bearing is disposed on the shaft, and a body connected to the shaft and coupled to be driven by the motor unit to rotate the shaft to drive the cylinder unit in response to motive power generated by the motor unit;
- and
- the load sensing unit comprises a load cell, which is arranged in parallel to the bearing, and configured to contact the shaft of the at least one reduction gear to sense a load produced from an axial force of the at least one reduction gear.
