Description

Technical Field

[0001] The utility model relates to a fixing bracket, in particular to a clutch actuator mounting bracket. Background Art

[0002] As the commercial vehicle market continues to develop in the direction of automation, intelligence, and high-end, matching AMT transmissions has become the mainstream choice for commercial vehicles. Currently, most AMT transmissions use pneumatic central clutch actuators to control the separation and engagement of the clutch.

[0003] For pneumatic central clutch actuators, when installing the whole vehicle, it is necessary to reserve space for the clutch installation on the front bearing end face of the central clutch actuator piston. However, since there is inevitably a seal leakage in the air path between the central clutch actuator and the transmission, after being left for a long time, the pre-compression function of the central clutch actuator will cause the piston to move to the end closest to the engine. Therefore, when assembling the clutch, since the closed cavity is formed inside the central clutch actuator, it is difficult to push the piston in a short time, so the clutch cannot be installed directly. The central clutch actuator needs to be removed again and the piston needs to be pressed into place before installation.

[0004] Existing mounting brackets are mostly fixed by input shafts, and some mounting brackets need to be tied with rubber bands. The structure of the mounting bracket is complicated. When the structure of the central clutch actuator changes (for example, with a fixed sealing cover), it cannot be used directly, and the application range is narrow.

[0005] Chinese patent CN210027041U discloses a clutch actuator bracket assembly, including a support, the longitudinal cross-section of the support is in the shape of a "J", the clutch actuator is detachably fixed to the top surface of the middle part of the support, the clutch actuator controller is detachably fixed to the front side or rear side of the support, and the left end and the right end of the support are respectively detachably and buffer-fixedly connected to the vehicle body.

[0006] Chinese patent CN202986829U discloses a manual-automatic hydraulic actuator assembly fixing bracket, including a fixing bracket body, and also including a left quick positioning pin and a right quick positioning pin. The left quick positioning pin fixes one end of the fixing bracket body to the clutch actuator, and the right quick positioning pin connects the other end of the fixing bracket body to the gear selection actuator sub-assembly.

[0007] However, the common disadvantages of the above-mentioned prior arts are: complex support structure and narrow application range. Utility Model Content
