The invention discloses a hydraulic parking braking system and method based on an electro-hydraulic brake. The system comprises the electro-hydraulic brake, a parking braking electromagnetic valve, a parking braking oil pipe, a parking braking hydraulic cylinder, a return elastic part, a piston, a balance rod, a left inhaul cable, a right inhaul cable and a wheel brake. Compared with manual parking braking, the parking braking device has the advantages of being large in braking force, easy to operate and capable of parking through programs. Compared with a common electronic parking brake, the electro-hydraulic brake is directly used as a power source, transmission mechanisms such as a parking brake motor, a worm and a worm gear are not needed, the structure is simple, and the cost is low. Meanwhile, the unsprung mass of the automobile is not increased, and the riding comfort of the automobile is not reduced.
本发明公开了一种基于电液制动器的液压驻车制动系统及方法,系统包括电液制动器、驻车制动电磁阀、驻车制动油管、驻车制动液压缸、回位弹性件、活塞、平衡杆、左拉索、右拉索和车轮制动器。本发明与手动的驻车制动相比,具有制动力大,操作简单,能通过程序来驻车的优点。与常用的电子驻车制动相比,直接利用电液制动器作为动力源,不需要驻车制动电动机、蜗杆蜗轮等传动机构,结构简单,成本低。同时还不增加汽车的非簧载质量,不降低汽车的乘坐舒适性。
