The invention discloses a hand brake pull rod system and a vehicle. The hand brake pull rod system comprises a crank arm and a hand brake chain connected to the crank arm, wherein the crank arm is rotationally connected to the positioning shaft, an elastic piece is connected between the crank arm and the positioning shaft, and the crank arm drives the hand brake chain to move in the preset relieving direction through reset force of the elastic piece. In the hand brake releasing process, after constraint of the hand brake chain is released, the elastic piece provides reset power for the hand brake chain, the elastic piece pulls the hand brake chain to move in the preset releasing direction, and after the elastic piece returns to the non-deformation original state, the hand brake chain is braked and released in place; automatic reset of the hand brake chain in the brake release process can be improved, and failure of hand brake release can be effectively avoided.
本发明公开了一种手制动拉杆系统及车辆。手制动拉杆系统包括拐臂和连接于拐臂的手制动链条,拐臂转动连接于定位轴上,拐臂与定位轴之间连接有弹性件,弹性件的复位力使拐臂带动手制动链条沿着预设缓解方向移动。在手制动缓解的过程中,松开对手制动链条的约束后,弹性件为手制动链条提供复位的动力,弹性件拉动手制动链条沿着预设缓解方向运动,当弹性件回复到不形变的原状后,手制动链条即制动缓解到位,可以提高手制动链条在制动缓解过程中的自动化复位,能够有效避免手制动缓解失效。
