摘要： In a liquid pump for a braking system of a vehicle, one end of a piston is slidably inserted into a cylindrical space of a housing member, and a sliding ring is provided on the piston. A suction chamber is formed by an inner peripheral surface of the housing member, an outer peripheral surface of the piston and the sliding ring. An inner diameter “Dk” of the housing member is made larger than an inner diameter “Dc” of the cylindrical space. As a result, the volume of the suction chamber is increased, without making the piston smaller in its diameter.

摘要： A brake control device for a vehicle includes a master cylinder, a wheel cylinder, a brake pedal behavior simulator, a normally-open type electromagnetic valve, a normally-closed type electromagnetic valve, and a brake pressure control device. The brake pressure control device includes a pump, a reservoir, and two electromagnetic valves to increase and decrease wheel cylinder hydraulic pressure. When the brake pressure control device is normally operated, a hydraulic pressure in the wheel cylinder is controlled by the brake pressure control device. On the other hand, when the brake pressure control device malfunctions or is abnormally operating, the wheel cylinder hydraulic pressure is controlled by hydraulic pressure generated from the master cylinder. At least the normally-closed type electromagnetic valve is opened when the brake pedal is in the non-operational state.

摘要： In an electric parking brake device, the force line of a motion transmitting force at a contact portion between a motion transmitting member and an intervention member is located inside of an outer surface of an engaging portion between a screw shaft member and a nut member. Thus, when a linear motion of the screw shaft member causes the parking lever to pivotally move, no floating takes place at the engaging portion, so that a one-side hitting can be prevented at the engaging portion. Therefore, the parking lever can be pivotally moved smoothly. Further, one surface of the motion transmitting member contacting the intervention member takes a curved surface to suppress a slippage in the movement that the parking lever is pivotally moved. Therefore, the motion transmitting force by the motion transmitting member can be prevented from becoming an offset load, realizing a smooth pivot movement of the parking lever.

摘要翻译： 在电动驻车制动装置中，运动传递构件和介入构件之间的接触部分处的运动传递力的力线位于螺杆轴构件和螺母构件之间的接合部分的外表面的内侧。 因此，当螺杆轴构件的直线运动导致停车杆枢转运动时，在接合部处不发生浮动，从而可以在接合部处防止单侧撞击。 因此，停车杆可以平稳地转动。 此外，与干涉构件接触的运动传递构件的一个表面采取弯曲表面以抑制驻车杆枢转运动的运动中的滑动。 因此，能够防止运动传递部件的运动传递力成为偏移负荷，实现驻车杆的平稳的枢转运动。
