Description

Hydraulic valve block and brake driving device comprising same Technical Field Embodiments of the present invention relate to a hydraulic valve block and a brake actuating apparatus including the same, and more particularly, to a hydraulic valve block and a brake actuating apparatus including the same, which can improve the life of the brake actuating apparatus by maintaining pressure balance inside the brake actuating apparatus. Background In general, a brake driving device provides braking force according to a stepping force of a pedal of a brake by a driver of a vehicle provided with the brake driving device. Such braking force is applied to wheels of the vehicle to reduce the vehicle speed, thereby realizing braking. By switching of the plurality of solenoid valves and the change of the position due to the hydraulic pressure, the magnitude of the braking force is changed according to the stepping force, thereby realizing the braking of the vehicle. In the case of a brake driving device requiring a compact installation space, the internal pressure thereof increases when the motor is operated, resulting in damage to the motor. Motor damage can reduce the life of the brake actuator and can be time and cost consuming to replace the brake actuator. Specifically, there is a problem in that the life of the brake driving device is shortened and the replacement cycle of the components constituting the brake driving device is shortened due to the increase of the motor and the internal pressure. [ Patent literature ] (Patent document 0001) Korean laid-open patent publication No. 10-2018-0032382 (publication day: 2018.03.30) Disclosure of Invention First, the technical problem to be solved Embodiments of the present invention provide a hydraulic valve block and a brake driving apparatus including the same, which can maintain pressure balance inside a motor unit when the motor unit is operated to cause the pressure of the motor unit to rise by communicating the inside of the motor unit with the outside thereof.
