The invention provides a parking braking device capable of reducing braking impact force, which comprises a hydraulic station, a hydraulic control system and a hydraulic control system, the energy accumulator is connected with the hydraulic station and used for storing pressure oil for emergency use; the energy accumulator electromagnetic valve is respectively connected with the hydraulic station and the energy accumulator and is used for controlling the oil pressure release of the energy accumulator; the parking braking electromagnetic valve is respectively connected with the one-way throttle valve and the hydraulic station and is used for controlling parking pull-up and release; the one-way throttle valve is connected with the parking braking electromagnetic valve and used for limiting pressure relief flow and reducing parking braking impact, the diameter of a throttle opening of the one-way throttle valve is # imgabs0 #, and A is the area of the throttle opening. The technical problems that in the prior art, an unmanned container truck suddenly parks and brakes due to misoperation and the like, braking impact force is too large, and an axle transmission system is damaged are solved.
本发明提供一种减小制动冲击力的驻车制动装置,所述装置包括:液压站,用于提供压力油源;蓄能器,与液压站相连,用于储存压力油,以便应急使用;蓄能器电磁阀,分别与液压站和蓄能器相连,用于控制蓄能器油压释放;驻车制动电磁阀,分别与单向节流阀和液压站相连,用于控制驻车拉起和释放;单向节流阀,与驻车制动电磁阀相连,用于限制泄压流量,减小驻车制动冲击,其中,单向节流阀节流口的直径#imgabs0#,A为节流口面积。解决现有技术中无人集卡因误操作等原因导致突然驻车制动,引起的制动冲击力过大,损坏车桥传动系统的技术问题。
