Problems solved by technology

[0002] With the development of locomotive-related technologies, automatic transmissions have gradually replaced manual transmissions and become the mainstream choice, and the clutch actuator is the most important part of the automatic transmission to achieve shifting. At present, there are many types of clutch actuators. Including hydraulic type, electric type, etc., the traditional hydraulic clutch actuator system is complex and prone to oil leakage, while the mechanical clutch actuator has a simple structure, but its transmission efficiency is low and the response time is long

Abstract

The invention discloses a pneumatic clutch actuating mechanism for an automobile transmission system, and belongs to the field of automobile transmission system accessories. The pneumatic clutch actuating mechanism comprises a valve body and an air cylinder, wherein the valve body and the air cylinder are connected with each other, a plurality of electromagnetic valves are arranged in the valve body, the plurality of electromagnetic valves are divided into two groups which are respectively connected with an air inlet channel and an air outlet channel of the valve body, and the electromagneticvalves in each group are connected in parallel; a piston is arranged in the air cylinder, and the interior of the air cylinder is divided into a rodless cavity and a rod cavity by the piston; the rodless cavity communicates with the air inlet channel and the air outlet channel, and a spring which sleeves the outer wall of the piston is arranged in the rodless cavity; and the rod cavity communicates with the atmosphere, and a push rod shifting block which is connected with the piston is arranged in the rod cavity. The pneumatic clutch actuating mechanism has the advantages of the simple structure and short response time, and the output thrust can be accurately controlled.

Description

technical field [0001] The invention belongs to the field of automobile transmission system accessories, and in particular relates to a pneumatic clutch actuator used in the automobile transmission system. Background technique [0002] With the development of locomotive-related technologies, automatic transmissions have gradually replaced manual transmissions and become the mainstream choice, and the clutch actuator is the most important part of the automatic transmission to achieve shifting. At present, there are many types of clutch actuators. Including hydraulic type, electric type, etc., the traditional hydraulic clutch actuator system is complex and prone to oil leakage, while the mechanical clutch actuator has a simple structure, but its transmission efficiency is low and the response time is long. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a pneumatic clutch actuator for automobile transmiss...
