Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0025] Such as figure 1 As shown, the present invention discloses an air path arrangement structure for an AMT transmission actuator, including a main air inlet A, a main exhaust port B, a main air intake air pressure adjustment part C, a shift part D and a clutch part E ; The main intake air pressure adjustment part C, the shift part D and the clutch part E are all connected with the control unit of the AMT transmission. The main air inlet A is connected to the air source of the vehicle, and the main exhaust port B is connected to the outside atmosphere. The compressed air of the main intake port A is connected with the main intake air pressure regulating part C and the clutch part E respectively.

[0026] The main intake air pressure adjustment part C is set between the main intake port A...

Abstract

The invention belongs to the technical field of AMT, and particularly discloses a gas circuit arrangement structure for an automatic mechanical transmission (AMT) actuating mechanism. The gas circuitarrangement structure for the AMT actuating mechanism comprises a main gas inlet, a main gas outlet, a main gas inlet pressure adjusting part, a gear shifting part and a clutch part, wherein the maingas inlet is connected with a gas source; the main gas inlet pressure adjusting part comprises two electromagnetic stop valves and a gas inlet pressure sensor; the gear shifting part comprises two gear shifting electromagnetic valves which are arranged in parallel; and the clutch part comprises a one-way valve, a gas inlet electromagnetic valve, a gas exhaust electromagnetic valve and a clutch gaspressure sensor. The two electromagnetic stop valves are used for controlling the flow of a gas circuit at a gas inlet circuit end, gas inlet pressure sensors are arranged at the rear ends of the electromagnetic stop valves to serve as control feedback of the electromagnetic stop valves, and proper pressure is provided for a gear shifting air cylinder through adjustment of the two gear shifting electromagnetic valves. The one-way valve ensures the safety of a clutch gas circuit, and the inflation rate of the clutch can be accurately controlled through the cooperative work of the two sensors,so that the movement rate of the clutch is accurately controlled.

Description

technical field [0001] The invention relates to the technical field of AMT transmissions, in particular to an air circuit structure for an actuator of an AMT transmission. Background technique [0002] After several years of popularization, the AMT penetration rate is still very low. With the increasingly stringent domestic emission regulations and the continuous improvement of drivers' requirements for vehicle comfort and economy, AMT transmissions will occupy more and more market shares in the domestic commercial vehicle market in the future. With the demand for miniaturization of the product structure of the main engine factory, the air supply pressure of the whole vehicle is getting higher and higher, and the volume of the air storage tank of the whole vehicle is compressed. However, during the continuous braking process of the vehicle, the air supply pressure of the vehicle fluctuates greatly, which causes the intake air pressure of the AMT actuator to be unstable, whi...
