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] like 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 an...

Abstract

The invention belongs to the technical field of AMT transmissions, and specifically discloses an air path layout structure for an AMT transmission actuator, including a main air intake, a main exhaust port, a main air intake pressure adjustment part, a gear shifting part and a clutch part, The main intake port is connected to the air source; the main intake air pressure adjustment part includes two electromagnetic cut-off valves and an intake air pressure sensor; the shift part includes two shift solenoid valves arranged in parallel; the clutch part includes a one-way valve, intake Solenoid valve, exhaust solenoid valve and clutch air pressure sensor. Two electromagnetic cut-off valves are used to control the flow of the air intake air path. An intake air pressure sensor is arranged at the rear end of the electromagnetic cut-off valve as the control feedback of the electromagnetic cut-off valve. The gear cylinder provides appropriate pressure; the one-way valve ensures the safety of the clutch air circuit, and through the cooperation of the two sensors, the inflation rate of the clutch can be precisely controlled, thereby accurately controlling the movement rate of the clutch.

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...
