The hydraulic transmission parking brake cylinder manual relieving auxiliary mechanism comprises a relieving handle (6) with one end hinged to a fixed installation support, and is characterized in that a driving oil cylinder assembly (5), an execution oil cylinder assembly (4) and a wedge block (3) are sequentially connected to the relieving handle, the wedge block is provided with a working inclined face, and the working inclined face is provided with a working inclined face. A ratchet pin (10) used for manual relieving is hung on the working inclined face in a lapped mode, in the initial state, the ratchet pin is hung at the lower end of the working inclined face in a lapped mode, and when manual relieving is executed, the wedge block moves under the action of hydraulic pressure provided by the driving oil cylinder assembly (5) and the executing oil cylinder assembly (4), so that the ratchet pin moves upwards along the working inclined face to achieve manual relieving. Hydraulic oil is adopted as a force transmission medium for manual relieving, the reliability of the whole manual relieving device is improved, the working efficiency is improved, and the labor intensity of an operator is reduced.
本发明公开了一种液力传动的停放制动缸手动缓解辅助机构及方法,其包括一端铰接在固定安装支架上的缓解手柄(6),其特征在于,所述缓解手柄上依次连接主动油缸组成(5)、执行油缸组成(4)及楔块(3),所述楔块具有一工作斜面,所述工作斜面上搭挂用于手动缓解的棘轮销(10),初始状态时,所述棘轮销搭挂在所述工作斜面的下端,执行手动缓解时,所述楔块在所述主动油缸组成(5)、执行油缸组成(4)提供的液压力作用移动,使所述棘轮销沿所述工作斜面上行实现手动缓解。本发明采用液压油作为手动缓解的传力介质,提高了整个手动缓解装置的可靠性,并提升了工作效率,降低了操作者的劳动强度。
