Abstract

The invention discloses a control valve group of a hydraulic clutch. The control valve group comprises a valve body, wherein a functional valve core is mounted on the valve body; the valve body is provided with connection openings; an oil duct is arranged in the valve body; the functional valve core comprises a first electromagnetic exchange valve, a second electromagnetic exchange valve, a P opening overflow valve, an AB opening overflow valve, a pilot operated directional control valve, an inserting valve and a one-way valve; the connection openings comprise a high voltage input opening P, a hydraulic clutch driving connection opening C, a hydraulic clutch lubricating connection opening F1, a functional valve core oil return opening T1, a lubricant passage way oil return opening T2, a cooler oil inlet connection opening L1 and a cooler oil outlet connection opening L2. The control valve group can meet the flow requirement of a system during normal operation, meanwhile can obtain more lubricant, properly lubricates the fully rotating control valve group and other parts, guarantees certain operating pressure in a lubricant passage way, balances oil pressure in all oil ducts, ensures that the fluctuation is relatively small, and simultaneously and effectively cools the system while lubricating the system.

Description

technical field [0001] The invention relates to a clutch pressure control valve group, in particular to a control valve group for a hydraulic clutch of a full-turn hydraulic clutch. Background technique [0002] The hydraulic clutch is a common clutch. When the pressure oil enters the clutch cylinder, the piston presses the friction disc against the baffle, so that the clutch produces frictional engagement. Once the pressure is reduced, the return spring resets the piston, so that the clutch is disengaged. Controlling the on-off of the hydraulic oil can control the engagement and disengagement of the clutch. At present, most hydraulic clutches use a relief valve and a reversing valve to control the working pressure of the clutch and the engagement and disengagement of the clutch. Some clutches also require A separate system cools and lubricates the clutch. In this commonly used system, the relief valve can only set one working pressure. Therefore, regardless of whether the ...
