Problems solved by technology

[0002] Existing vehicle transmissions can only rely on the slider on the synchronizer to apply axial pressure on the synchronizer ring during the pre-synchronization stage to make it pre-synchronized, resulting in a longer shift time and a larger synchronization impulse when shifting gears. Makes it uncomfortable when shifting gears
In addition, in the existing synchronizer structure, when the clutch sleeve enters the reserve amount, there is also a large speed difference between the clutch sleeve and the engaging teeth, which is prone to secondary impact and reduces the shift quality

Embodiment 1

[0033] The invention relates to a slider for a synchronizer, which includes a slider body embedded on the outer peripheral surface of the gear hub and capable of sliding along the axial direction of the gear hub. The protruding power bearing part and the push part slidingly arranged in the slider body along the synchronous direction of the slider body; The transmission part between the pusher part and the push part. When the power bearing part receives an external force and retracts in the slider body, the transmission part can drive the push part due to the drive of the power bearing part. The push part protrudes from the slider body.

[0034] When the slider of the synchronizer is synchronizing, when the power bearing part retracts in the slider body due to the radial pressure of the adapter sleeve, the driving part can drive the push part to protrude in the slider body through the transmission part, so that the slider The main body and the pushing part jointly crimp the sy...

Embodiment 2

[0042] This embodiment relates to a synchronizer, which includes a gear hub, a synchronizing ring located on one side of the gear hub, a coupling tooth, and an adapter sleeve fitted on the gear hub. slider.

[0043] At the same time, this embodiment also relates to a vehicle, which is equipped with the above-mentioned synchronizer.

[0044] The synchronizer and the vehicle of this embodiment can increase the synchronous torque of the synchronous ring during synchronization by using the synchronizer slider in the first embodiment, so as to reduce the shifting time, reduce the synchronous impulse, and improve the shifting quality. Moreover, after the engaging sleeve enters the synchronizing ring, the rotational speed difference between the engaging sleeve and the idle gear at the input end during shifting can also be reduced, reducing the occurrence probability of secondary impact and having a better use effect.

Abstract

The invention relates to a synchronizer slide block and a synchronizer and a vehicle. The synchronizer slide block comprises a slide block body embedded in the outer peripheral surface of a gear hub, a power bearing part slidingly arranged in the slide block body, and an ejecting part slidingly arranged in the slide block body in the synchronization direction of the slide block body, wherein one end of the power bearing part is ejected out by the top of the slide block body. The synchronizer slide block further comprises a transmission part slidingly arranged in the slide block body and elastically butting between the power bearing part and the ejecting part. When the synchronizer slide block is synchronized, a synchronous ring can be synchronously pressed through the slide block body and the ejecting part, so that the synchronous torque of the synchronous ring is increased, the gear shifting time can be shortened, the synchronous impulse is reduced, and the gear shifting quality is improved. After a joint sleeve is fed in the synchronous ring, the synchronous ring can be continuously pressed by the ejecting part, so that the rotating speed difference between the gear shifting joint sleeve and an input end idle gear in the period of the joint sleeve entering the reserve quantity can be reduced, the generation probability of secondary impulse is reduced, and the synchronizer slide block achieves better use effect.

Description

technical field [0001] The invention relates to the technical field of synchronizers, in particular to a synchronizer slider. The invention also relates to a synchronizer equipped with the synchronizer sliding block and a vehicle with the synchronizer. Background technique [0002] Existing vehicle transmissions can only rely on the slider on the synchronizer to exert axial pressure on the synchronizing ring during the pre-synchronization stage to make it pre-synchronized, resulting in a longer shift time and a larger synchronous impulse when shifting gears. Makes it uncomfortable when shifting gears. In addition, in the existing synchronizer structure, when the clutch sleeve enters the reserve amount, there is also a large speed difference between the clutch sleeve and the coupling teeth, which is prone to secondary impact and reduces the shifting quality. Contents of the invention [0003] In view of this, the present invention aims to propose a synchronizer slider to ...
