[0002] The existing gearbox gear control valve adopts an integral structure, because the gearbox gear control valve has high precision requirements for each component and the relative positional relationship between the components, while the gearbox gear control valve There are many internal parts; therefore, the traditional integral transmission gear control valve is difficult to process, prone to waste products, and its processing cost is high; and when one part of the transmission gear control valve is damaged during use , it is more difficult to maintain, and the entire control valve is often discarded due to damage in one place, and the waste phenomenon is very serious

Embodiment Construction
[0008] The invention includes a plurality of split main pressure control valves, safety valves, torque converter outlet pressure regulating valves, gear reversing valves and buffer valves, and each valve is assembled to form an integral gear control valve.
[0009] The function of the main pressure control valve of the present invention is to control the gear pressure at about 1.5Mpa; the function of the safety valve is to control the oil pressure flowing into the torque converter at about 0.8Mpa.
[0010] The torque converter outlet pressure regulating valve of the present invention controls the outlet oil pressure of the torque converter at 0.5Mpa, thereby ensuring that the torque converter always has a certain amount of oil.
[0011] The gear reversing valve of the present invention is composed of six HydraForce cartridge valves, including forward valve, reverse valve, gear valve one, gear valve two, gear valve three, and gear valve four; it is compatible with EPEC Used tog...

The invention relates to a gearbox gear control valve which comprises a main pressure control valve, a safety valve, a torque converter outlet pressure regulating valve, gear reversing valves and a buffering valve, and the main pressure control valve, the safety valve, the torque converter outlet pressure regulating valve, the gear reversing valves and the buffering valve are arranged in a split mode and are assembled to form the integrated gear control valve. The split structure overcomes the defects of a control valve of an integrated structure, the requirement for machining precision is lowered, and production cost is greatly lowered. When the gearbox gear control valve is damaged, corresponding damaged parts just need to be replaced, repair is simple and convenient, waste due to the fact that the whole gear control valve is scrapped due to one damaged part is greatly avoided, and the gearbox gear control valve meets the development tendency of the current conservation-oriented society and has practicability.
Description
technical field [0001] The invention relates to a gearbox gear control valve. Background technique [0002] The existing gearbox gear control valve adopts an integral structure, because the gearbox gear control valve has high precision requirements for each component and the relative positional relationship between the components, while the gearbox gear control valve There are many internal parts; therefore, the traditional integral transmission gear control valve is difficult to process, prone to waste products, and its processing cost is high; and when one part of the transmission gear control valve is damaged during use , It is more difficult to maintain, and the whole control valve is often discarded due to one damage, and the waste phenomenon is very serious. Contents of the invention [0003] The purpose of the present invention is to provide a gearbox gear control valve with a split structure in order to address the above defects. [0004] For this reason, the tec...
