Embodiment Construction
[0020] Such as Figure 1-6 A commercial vehicle cab transisculation system displays a differential valve, a relief valve (safety valve), commutation valve, and the oil pool, in the valve plate, to constitute an integrated hydraulic power unit. Implement the differential oil supply system, and it can also be used to turn it into a single loop oil supply system, and it can also connect the electric oil pump to implement electric operation. The specific features are as follows:
[0021] The one-way valve, a relief valve (safety valve), the commutation valve is integrated inside the valve plate, the oil pool is fixed to the side of the valve plate, and the switching of the differential oil supply system is achieved by the adjustment of the vane. .
[0022] The internal characteristics of the valve panel are as follows:
[0023] There is an interface A, interface B, and interface C in the valve plate, where interface A, interface B is connected to the cylinder, and the interface C is co...
