Embodiment Construction

[0027] 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.

[0028] The present invention provides a dual air path connection structure between a clutch actuator and a shifting mechanism. The dual air path connection mechanism is arranged in a clutch housing. There is a clutch actuator 17. An air passage is provided between the clutch actuator 17 and the shift mechanism 11 . see figure 1 , the clutch solenoid valve 10 is located inside the shift mechanism 1, the clutch actuator 17 includes a housing inner ring 14, an actuator housing 15 and a piston 4, the housing inner ring 14 is arranged in the actuator housing 1, and the housing inner ring The bottom of 14 is integrally connected with the bottom of the actuator housing 15, and the two ends of the intake and exhaust gas passage 12 communicate with the inside of the actuator housing 15 and the insid...

Abstract

The invention discloses a gas circuit structure of a clutch actuator and a gear shifting mechanism and a gear box. A double-circuit structure is arranged in the gear shifting mechanism and the clutch actuator, the service life of the clutch actuator can be greatly prolonged through the use of a double-gas-circuit clutch actuator, and compared with a passive defense mode of a traditional single-gas-circuit clutch actuator, the service life and reliability of the double-gas-circuit clutch actuator are obviously better than those of an existing technical scheme. Waste gas in the gear shifting mechanism is led to the front end of the clutch actuator to be exhausted to an actuator shell, exhaust noise can be reduced, and compared with the mode that waste gas is directly exhausted to the outside of the gear shifting mechanism in the prior art, high-frequency noise can be remarkably reduced, the NVH level of a whole vehicle can be improved, and the risk that a ventilation opening is blocked is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of AMT transmission protection, in particular to an air circuit structure of a clutch actuator and a shifting mechanism and a transmission. Background technique [0002] As a core component of the AMT transmission, the clutch actuator plays a pivotal role in the process of vehicle starting and transmission shifting. With the continuous development of AMT technology, the integrated design of AMT transmission has fewer external wiring harnesses and components and high reliability. Therefore, the actuators of AMT transmissions are mostly composed of two parts on heavy trucks, that is, the concentric clutch actuator and the shift mechanism. The two are connected through the wiring harness and the air circuit. The gas path is cast inside the housing. [0003] At present, the clutch actuator is connected to the shifting mechanism by a single air path, that is, the intake and exhaust air path. Since the clutch ac...
