The invention relates to a low dragging brake system device and a control method thereof, the device comprises a brake caliper piston, a sealing groove and a sealing ring, the sealing ring is arranged in the sealing groove, and the brake caliper piston returns through resilience force of the sealing ring; the sealing groove comprises a sealing groove body, a sealing groove front bottom edge and a sealing groove rear bottom edge, a sealing groove front chamfer part is arranged between the sealing groove front bottom plate and the sealing groove body, and a sealing groove rear chamfer part is arranged between the sealing groove rear bottom plate and the sealing groove body; the sealing groove front chamfer part comprises a bevel edge part and an arc-shaped part, the upper edge of the bevel edge part is connected with the sealing groove body, the lower edge of the bevel edge part is connected with the upper edge of the arc-shaped part, and the lower edge of the arc-shaped part is connected with the sealing groove front bottom edge. According to the technical scheme, dragging torque of the braking system can be remarkably reduced, so that service life of the braking system is prolonged, power consumption of the whole vehicle is reduced, and driving range of the electric vehicle is increased.

    本发明涉及一种低拖滞制动系统装置及其控制方法,装置包括制动卡钳活塞、密封槽及密封圈,密封圈设置于密封槽内,制动卡钳活塞通过密封圈的回弹力进行回位;密封槽包括密封槽本体、密封槽前底边及密封槽后底边,所述密封槽前底板与密封槽本体之间设置有密封槽前倒角部,密封槽后底板与密封槽本体之间设置有密封槽后倒角部;密封槽前倒角部包括斜边部和弧形部,斜边部的上边连接密封槽本体,斜边部的下边与弧形部的上边连接,弧形部的下边与密封槽前底边连接。本技术方案可显著降低制动系统拖滞力矩,从而延长制动系统使用寿命,降低整车功耗,提高电动车续驶里程。
