Embodiment Construction

[0014] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings

[0015] Such as Figure 1-Figure 7 As shown, the integral multifunctional full hydraulic steering gear includes a valve body 1, and the valve body 1 is formed with an oil inlet 11, an oil return port 12, a left oil port 13 and a right oil port 14, and is characterized in that the valve body 1 is formed with a safety valve hole 15, two oil supply valve holes 16 and two two-way overload valve holes 17, and a check valve 4 is installed in the oil inlet 11 to prevent high-pressure oil from flowing backward; a safety valve hole 15 is installed in the safety valve hole. Valve 2, the safety valve 2 is connected with the oil inlet 11, when the oil inlet pressure exceeds the set pressure of the safety valve 2, the high-pressure oil in the oil inlet 11 pushes the safety valve spool, and the high-pressure oil is discharged into the oil return port 12 , to realize th...

Abstract

The invention relates to an integral multifunctional all-hydraulic steering gear, which comprises a valve body. An oil inlet, an oil return port, a left oil port and a right oil port are formed on the valve body; and a safety valve opening, two oil supplementing valve openings and two bidirectional overload valve holes are formed on the valve body. A one-way valve is arranged in the oil inlet; a safety valve is arranged in the safety valve opening and is communicated with the oil inlet; oil supplementing valves are arranged in the oil filling valve openings and are communicated with the oil return port; bidirectional overload valves are arranged in the bidirectional overload valve holes; and the two bidirectional overload valves are communicated with the left oil port and the right oil port. The one-way valve, the safety valve, the oil supplementing valves and the bidirectional overload valves are integrated in the valve body of the steering gear. The integral multifunctional all-hydraulic steering gear has the advantages of difficult oil leakage compared with the prior art by connecting through valve blocks, and also has the advantages of compact structure, small volume and convenient installation.

Description

technical field [0001] The invention relates to a full hydraulic steering gear, in particular to an integral multifunctional full hydraulic steering gear. Background technique [0002] In the prior art, in order to ensure the safety of the steering system, a combined valve block is usually installed on the full hydraulic steering gear. The combined valve block includes a safety valve, a two-way overload valve, a one-way valve and an oil filling valve. Safety valve includes safety valve seat, safety valve core, spring and other structures; two-way overload valve includes overload valve seat, steel ball, steel ball seat, spring and other structures; oil replenishment valve is composed of pin and steel ball. They respectively provide the safety protection of the system pressure, the buffer protection of the steering cylinder and prevent the steering cylinder from cavitation, high-pressure oil backflow and impact on the steering wheel. The safety valve, two-way overload valve, ...
