Description

Technical Field

[0001] The utility model relates to a synchronizer slider which is convenient for changing gear positions and belongs to the field of synchronizer sliders. Background Art

[0002] The synchronizer makes the gears to be meshed reach the same speed and mesh smoothly. It can adjust the vehicle's speed change and adjust the speed difference of the gears. The synchronizer is made up of multiple gears connected together, and is connected and matched internally by multiple different parts.

[0003] In the prior art, when the synchronizer adjusts the gear, it cooperates with the connected slider to make the gear adjustment smoother and more stable. Since some vehicles need to adjust high and low gears, the synchronizer slider is greatly worn, which reduces the service life of the synchronizer slider. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a synchronizer slider that is convenient for changing gears, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above object, the utility model is implemented by the following technical solution: a synchronizer slider for convenient gear change, comprising a spline hub, the outer wall of the spline hub is provided with a slider groove, and the inner wall of the slider groove is provided with a connecting spring;

[0006] A connecting slider is arranged at one end of the connecting spring, and a ball assembly is arranged inside the connecting slider.

[0007] Preferably, the outer wall of the spline hub is provided with a plurality of grooves, and meshing gears are formed between the grooves.

[0008] Preferably, the slider grooves are respectively opened around the outer wall of the spline hub, and the inner wall surface of the spline hub is tightly fitted with the outer wall surface of the connecting spring.

[0009] Preferably, the connecting slider is placed inside the slider groove, and the center axis of the connecting slider coincides with the center axis of the connecting spring.

[0010] Preferably, the connecting slider is hooked onto the outer wall of the ball assembly, and the installation positions of the connecting sliders are opposite.

[0011] Preferably, the ball assembly comprises a round ball, an outer wall of the round ball is provided with a limit plate, a small spring is fixedly connected below the limit plate, and the outer wall of the small spring is tightly fitted with a fixed plate.

[0012] Preferably, the limiting plate is movably hooked at two-thirds of the circular bead, and the outer wall surface of the small spring is tightly fitted with the inner wall surface of the fixing plate.

[0013] Beneficial effects of the utility model:

[0014] Compared with the prior art, the synchronizer slider which is convenient for changing gears has a connection in which one side of the slider is wide and the other side is narrow by connecting the slider and the ball assembly. When the vehicle adjusts the height gear, the wide side has a greater bearing force, which is beneficial for the vehicle to change the gear. At the same time, when the slider is docked, one end of the wide side is connected to the wide teeth of the locking ring, so that when it is installed and connected to the locking rings on both sides, the position of the wide side is connected, which can improve stability when adjusting the high and low gears, and can be used in conjunction with the internal ball assembly to increase the service life of the internal slider.

[0015] Compared with the prior art, the synchronizer slider which is convenient for changing gears is used internally through a ball assembly. When the slider is adjusting the speed, the internal round ball can contact the external coupling sleeve, and the internal round ball can slightly decrease its elasticity through a small spring. Therefore, while reducing wear, it can also play the role of adjusting the connection of the upper coupling sleeve. BRIEF DESCRIPTION OF THE DRAWINGS
