Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of automobile transmission, especially relates to a modular AMT separation yoke binding fixing structure of automobile. BACKGROUND

[0002] The modular AMT of commercial vehicle is composed of the body of mechanical transmission, external hanging gear selecting and shifting execution mechanism, clutch execution mechanism, transmission controller (TCU), electromagnetic valve, sensor and control wire harness etc. The modular AMT mostly matches push type clutch, and the push rod on the clutch execution mechanism is used to push the separation yoke, and then the separation bearing fixed on the yoke is used to push the clutch separation finger, so as to realize the separation and combination of the clutch.

[0003] At present, the clutch execution mechanism of the modular AMT of commercial vehicle is assembled on the transmission, and then the whole machine is sent to the main machine factory for vehicle installation. During the transportation of the transmission from the warehouse to the remote place or the workshop of the main machine factory, the separation bearing slides on the shaft bearing sleeve due to long time jolting transportation, and then the separation yoke moves, so as to cause the separation yoke support end to be separated from the supporting pin and the clutch push rod to be separated from the ball socket of the separation yoke bushing. The separation of the supporting pin and the push rod can cause the displacement value of the clutch to change or even be abnormal, and the wrong displacement value of the clutch can affect the control of the separation and combination of the clutch of the AMT, and cause the gear to be not hung, which seriously affects the driving safety.

[0007] A bolt hole matched with the installation hole of the connecting plate is formed in the position close to the elastic cylindrical pin on the inner wall of the transmission housing, and the transmission housing and the connecting plate of the binding support are screwed.

[0008] The bundling device is sequentially arranged through the bundling hole of the bundling support and the inner hole of the separation fork, and is fixedly connected with the separation fork and the bundling support.

[0009] The utility model discloses still have the following characteristics:

[0010] Further, the bundling device is a cable tie.

[0011] Further, one end of the cable tie extends outside the transmission housing from the mounting hole of the transmission housing.

[0012] Compared with the prior art, the utility model has the following technical effects:

[0013] The automobile modularization AMT separation fork bundling fixing structure sets the new bundling support on the inner side of the clutch housing, and uses the cable tie to bundle the separation fork, meets the demand of separation fork fixing in the AMT transportation process, avoids the problem that the fork fulcrum end is separated from the supporting pin and the clutch push rod is separated from the separation fork ball socket because of the movement of the separation fork.

[0014] In addition, the setting uses the bolt position of the mounting connection of the original clutch housing and the transmission housing to install the bundling support, does not change the original clutch housing and the transmission housing structure, and is suitable for large-scale use and popularization in industry.
