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. Ma

Example Embodiment

[0032] Example 1

[0033] The invention relates to a synchronizer slider, which comprises a slider body embedded on the outer peripheral surface of the gear hub and slidable along the axial direction of the gear hub. The protruding power bearing portion and the push portion slidingly arranged in the slider body along the synchronizing direction of the slider body; the synchronizer slider also includes a sliding portion arranged in the slider body and elastically abutting against the power bearing portion. When the power bearing part receives an external force and retracts in the slider body, the transmission part is driven by the power bearing part to drive the ejector part. The push portion protrudes from the slider body.

[0034] When the synchronizer slider is synchronized, when the power bearing part is retracted in the slider body due to the radial pressure of the engaging sleeve, the pushing part can be driven to protrude from the slider body through the transmission pa...

Example Embodiment

[0041] Embodiment 2

[0042] The present 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 engagement sleeve sleeved on the gear hub, and the gear hub is embedded with the synchronizer described in the first embodiment. slider.

[0043] Meanwhile, the present embodiment also relates to a vehicle on which the above-mentioned synchronizer is installed.

[0044] By using the synchronizer slider in the first embodiment, the synchronizer and the vehicle of this embodiment can increase the synchronizing torque of the synchronizing ring during synchronization, so as to reduce the shifting time, reduce the synchronizing impulse, and improve the shifting quality. In addition, after the adapter sleeve enters the synchronizing ring, the speed difference between the shift adapter sleeve and the idle gear at the input end can be reduced during the period when the adapter sleeve enters the bac...

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 ...
