Abstract
A brake apparatus for a vehicle, comprising: a 3-way solenoid valve unit including one or more 3-way solenoid valves, a valve block having a first surface on which the 3-way solenoid valve unit is installed, at least one accumulator, a pressurizing unit, and a plurality of wheel cylinders, wherein each 3-way solenoid valve includes a first port, a second port, a third port, a first opening/closing flow path, and a second opening/closing flow path, and at least a part of the at least one accumulator is disposed between the 3-way solenoid valve unit and a second surface of the valve block.
Claims11
A brake apparatus for a vehicle, comprising:
- a 3-way solenoid valve unit including one or more 3-way solenoid valves;
- a valve block having a first surface on which the 3-way solenoid valve unit is installed;
- at least one accumulator configured to store a working fluid;
- a pressurizing unit configured to pressurize the working fluid;
- and
- a plurality of wheel cylinders configured to restrict rotation of vehicle wheels using a hydraulic pressure of the working fluid,
- wherein each 3-way solenoid valve includes a first port, a second port, a third port, a first opening/closing flow path configured to allow the first port and the second port to fluidly communicate with each other or to block the first port and the second port from each other, and a second opening/closing flow path configured to allow the second port and the third port to fluidly communicate with each other or to block the second port and the third port from each other,
- at least a part of the at least one accumulator is disposed between the 3-way solenoid valve unit and a second surface of the valve block,
- the pressurizing unit includes a master cylinder configured to generate a hydraulic pressure corresponding to a brake signal,
- a traction control valve is installed on a flow path connecting the master cylinder and the 3-way solenoid valve unit, and
- the traction control valve is disposed further away from a center axis of the valve block than the 3-way solenoid valve unit in a width direction of the valve block, wherein the second surface of the valve block and an opposite surface thereof oppose each other in the height direction and the width direction is perpendicular to the height direction.
