Abstract

The invention relates to a clutch control valve which comprises a valve body and a valve element. The valve element comprises a head and a tail, and a neck is arranged between the head and the tail. Valve grooves are formed in the connection position between the neck and the head and the connection position between the neck and the tail. Pressure equalizing grooves are formed in the head and the tail respectively. The clutch control valve has the advantages that the valve element is high in response speed and oil discharging speed and used for correcting and controlling flows needed for a system, and accurate and stable control in the whole hydraulic system is achieved.

Description

technical field [0001] The invention relates to a control valve suitable for a multi-speed automatic transmission, in particular to a clutch control valve and belongs to the field of mechanical technology. Background technique [0002] At present, the commonly used clutch control valve includes a valve body, a valve cavity is arranged in the valve body, a valve core is arranged in the valve cavity, and a number of oil circuits are arranged on the valve body, and the connection and disconnection between the oil circuits are realized through the movement of the valve core. open. [0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art. In actual operation of the valve core, the response speed is slow, and at the same time, the flow cannot be adjusted and controlled. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a clutch contro...
