The invention provides a fully-hydraulic reverse braking
clutch system, and belongs to the technical field of
hydraulic pressure. The fully-hydraulic reverse braking
clutch system solves the problem that the power
cut-
off time is difficult to control in the
brake process of an existing
braking system. The fully-hydraulic reverse braking
clutch system comprises an
oil pump, a braking valve, a brakeand a speed change gear; the braking valve communicates with the
oil pump through a first oil inlet way, the braking valve communicates with the
brake through a first working oil way, the braking valve controls the
brake to conduct reverse braking, and a hydraulic-control
reversing valve is arranged between the first oil inlet way and the brake; and a second oil inlet of the hydraulic-control
reversing valve communicates with the first oil inlet way through a second oil inlet way, a second working oil opening communicates with a power
cut-off control oil opening of the speed change gear through a second working oil way, the control oil opening communicates with the first working oil way, and when the pressure of the first working oil way is descended to the set value of the hydraulic-control
reversing valve, the hydraulic-control reversing valve reverses to enable the second oil inlet way to communicate with the second working oil way. According to the fully-hydraulic reverse brakingclutch system, power can be
cut off under the appropriate time in the brake process, and the driving comfort and safety of a vehicle are improved.
