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...

Abstract

The invention provides a differential hydraulic pump for a commercial vehicle cab turnover system. The differential hydraulic pump comprises a one-way valve, an overflow valve and a reversing valve, wherein the one-way valve, the overflow valve and the reversing valve are integrated in a valve plate, an oil pool is fixed to one side of the valve plate, three interfaces are arranged in the valve plate, two interfaces are connected with an oil cylinder, and the other interface is connected with an electric pump. The differential hydraulic pump for the commercial vehicle cab turnover system is simple in structure and low in cost; and the differential lifting principle is fully utilized by the oil pump, and one of two oil ways is controlled, so that the size and machining difficulty of the reversing valve are reduced, and the cost is reduced by about 20%.

Description

Technical field [0001] The present invention relates to a commercial vehicle hydraulic system power unit, in particular a differential hydraulic pump for commercial vehicle cabling systems. Background technique [0002] Nowadays, there are now a non-prone part of the manual pump, one side provides the allocation conversion of the oil passage, and provides a reliable power output. From the system perspective, it can be divided into two types of differential systems and non-differential systems. In both systems, the differential system is widely used in the modern commercial vehicle cabling due to its simple principle, convenient manufacturing. [0003] At this stage, the manual pump replacement valve and the rocker arm are distributed in two different dimensions. The rocker arm is the connection portion of the external mechanical force to the internal pressure of the hydraulic system, and the convenience of the operation should be taken into account when designing the vehicle. . H...
