Abstract
Description
Technical Field
[0001] This utility model relates to the field of synchronizer technology, specifically to an adjustable gearbox synchronizer assembly. Background Technology
[0002] Because the input and output shafts of a transmission rotate at their own speeds, a "synchronization" issue arises when shifting gears. Forcing gears with different rotational speeds to mesh will inevitably cause impact and damage. Therefore, older transmissions required a "double-clutch" method for shifting gears: pausing briefly in neutral for upshifting and accelerating in neutral for downshifting to reduce the speed difference between the gears. However, this operation was complex and difficult to master precisely. Therefore, designers created a "synchronizer," which ensures that the gears to be engaged rotate at the same speed for smooth engagement.
[0003] The current mainstream synchronous ring adopts an integral structure design. Although this design reduces the manufacturing difficulty, it means that once the bar teeth wear out, the entire synchronous ring needs to be replaced, which increases maintenance costs. Utility Model Content
[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0005] Therefore, the technical solution adopted by this utility model is as follows: An adjustable gearbox synchronizer assembly includes a shifting mechanism and a protection mechanism. The shifting mechanism includes a synchronizing ring, multiple strip teeth fixed to the inner wall of the synchronizing ring, a tooth seat meshing between the multiple strip teeth, three sliders and pins slidably installed between the synchronizing ring and the tooth seat. The protection mechanism includes two slag grooves opened on the inner side of the strip teeth, a magnetic plate detachably installed inside the slag grooves, a buckle plate that snaps onto the strip teeth, and four insert tubes inserted between the strip teeth and the buckle plate. Locking assemblies are provided on both sides of the slag grooves.
[0006] By adopting the above technical solution, when a single or multiple buckle plates are worn, the insert tube is pulled out, then an external tool is inserted into the slot and pried open the buckle plate. After the buckle plate is separated from the slot, it can be removed and replaced with a new buckle plate. This targeted repair operation greatly reduces the cost of use.
[0007] In a preferred embodiment, the present invention can be further configured as follows: four insertion tubes are arranged in pairs, forming two groups, with two insertion tubes in each group respectively communicating with the interior of two slag tanks.
[0008] In a preferred embodiment, the present invention can be further configured such that the locking assembly includes a slot formed on the side wall of the strip tooth and a locking plate engaged inside the slot, wherein the locking plate and the buckle plate are integrally formed.
[0009] In a preferred embodiment, the present invention can be further configured such that: a slot is provided on the card plate, and the slot is close to the outer side of the card plate.
[0010] In a preferred embodiment, the present invention can be further configured such that: the outer edge of the slot is provided with an arc surface, and the arc surface is provided on one side of the slot.
[0011] In a preferred embodiment, the present invention can be further configured such that: both the top and bottom of the toothed seat are provided with compression springs, which are engaged between the three sliders and the pin.
[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. In this utility model, when a single or multiple buckle plates are worn, the insert tube is pulled out, then an external tool is inserted into the slot and pried open the buckle plate. After the buckle plate is separated from the slot, the buckle plate can be removed and a new buckle plate can be replaced. This targeted repair operation greatly reduces the cost of use.
[0013] 2. In this utility model, when the slider and pin move, they push the metal slag generated by wear inside the synchronizer into the insertion tube. The slag enters the slag trough and is attracted by the magnetic plate, thereby preventing the slag from flowing back and preventing further wear of the synchronizer, thus extending the service life of the synchronizer to a certain extent.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0017] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0018] The adjustable gearbox synchronizer assembly provided by some embodiments of the present invention is described below with reference to the accompanying drawings.
[0019] Example 1 Combination Figure 1-4 As shown, the adjustable gearbox synchronizer assembly provided by this utility model includes a shifting mechanism 100 and a protection mechanism 200. The shifting mechanism 100 includes a synchronizer ring 110, a plurality of strip teeth 120 fixedly connected to the inner wall of the synchronizer ring 110, a tooth seat 130 meshing between the plurality of strip teeth 120, and three sliders and pins 140 slidably installed between the synchronizer ring 110 and the tooth seat 130. The protection mechanism 200 includes two slag troughs 210 opened inside the strip tooth 120, a magnetic plate 220 detachably installed inside the slag trough 210, a buckle plate 230 that is fastened to the strip tooth 120, and four insertion tubes 240 inserted between the strip tooth 120 and the buckle plate 230. Locking components 300 are provided on both sides of the slag trough 210.
[0020] Furthermore, the four insertion tubes 240 are arranged in pairs, forming two groups. In each group, two insertion tubes 240 are connected to the interior of two slag tanks 210. The insertion tubes 240 can improve the connection between the buckle plate 230 and the strip tooth 120.
[0021] Furthermore, the toothed seat 130 is provided with compression springs 600 at both the top and bottom. The compression springs 600 are engaged between the three sliders and the pins 140. A pressure ring 600 is provided to limit the sliders and pins 140 and prevent them from falling off.
[0022] Example 2 Combination Figure 3-4 As shown, based on Embodiment 1, locking components 300 are provided on both sides of the slag trough 210. The locking component 300 includes a slot 320 formed on the side wall of the strip tooth 120 and a locking plate 310 locked inside the slot 320. The locking plate 310 and the buckle plate 230 are integrally formed. The locking plate 310 and the slot 320 cooperate to further strengthen the connection between the buckle plate 230 and the strip tooth 120.
[0023] Example 3 Combination Figure 3-4 As shown, in the above embodiment, the card plate 310 has a slot 400, which is located near the outside of the card plate 310, and the slot 400 provides conditions for prying open the card plate 310.
[0024] Furthermore, the outer edge of the slot 400 is provided with an arc surface 500, which is located on one side of the slot 400. The arc surface 500 facilitates the insertion of external tools into the slot 400.
[0025] The working principle and usage process of this utility model are as follows: During the use of this device, the buckle plate 230 serves to protect the strip tooth 120. When the slider and pin 140 move, the metal slag generated by wear in the synchronizer is pushed into the insertion tube 240. The slag enters the slag trough 210 and is attracted by the magnetic plate 220, thereby preventing the slag from flowing back and preventing further wear of the synchronizer. When a single buckle plate 230 or multiple buckle plates 230 are worn, the insertion tube 240 is pulled out. Then, an external tool is inserted into the slot 400 and pried open the buckle plate 230. After the clamping plate 310 is separated from the slot 320, the buckle plate 230 can be removed and a new buckle plate 230 can be replaced. This targeted repair operation greatly reduces the cost of use.
[0026] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
