Description

Technical Field

[0001] The utility model relates to the technical field of automobile differential reducers, in particular to a spline detection tool for differential reducers of new energy vehicles. Background Art

[0002] The main functions of a car's differential reducer are to slow down, increase torque, and differential left and right. The output power of the engine is certain. When the transmission speed is reduced by the main differential reducer, a higher output torque can be obtained, thereby obtaining a greater driving force. In addition, the differential reducer also has the function of changing the direction of power output to achieve differential between the left and right wheels or the center and rear axles.

[0003] During the use of automobile differential reducers, the splines of the differential reducer input shaft will inevitably wear out. The input shaft with excessive spline wear will cause changes in the overall performance of the differential reducer. When the spline wear of the differential reducer input shaft exceeds 0.08mm, the use of the input shaft will be affected due to excessive wear. Although the wear of the spline can be observed by the eyes, it is impossible to accurately judge whether the spline wear exceeds the threshold of 0.08mm. It is difficult to judge whether the spline can be used normally after wear, which is easy to cause cost waste due to ambiguity. Utility Model Content

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing the embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0025] The utility model provides a new energy vehicle differential reducer spline detection tool, which is achieved by arranging a fixed ring on the top of the base, wherein the radius of the fixed ring is 0.08 mm smaller than the radius of the spline, and a slider is arranged on the top of the base, and a clamping plate is arranged on the top of the slider, and the input shaft is fixed between the two clamping plates, with the spline facing the fixed ring. By pushing the slider, the input shaft and the spline are driven to move toward the fixed ring. By observing whether the spline can pass through the fixed ring, it can be intuitively analyzed and judged whether the input shaft of the differential reducer can continue to be used, thereby avoiding cost waste caused by ambiguity, saving costs and improving efficiency.

[0026] Figure 1-3 The following is a schematic diagram of a new energy vehicle differential speed reducer spline detection tool embodiment of the utility model, please refer to Figure 1-Figure 3In this embodiment, a new energy vehicle differential reducer spline detection tool includes a base 100, a slider 200 and a clamping plate 300.

[0027] A support frame 110 is installed at the front end of the base 100, and a fixed ring 120 is installed on the top of the support frame 110. When the working surface of the spline teeth wears, the radius in the spline parameters will become smaller. After many experiments, the wear limit of most splines is negative 0.08mm. After exceeding this value, the overall performance of the differential reducer will change. Therefore, the inner ring diameter of the fixed ring 120 is 0.08mm smaller than the diameter of the spline. When the spline wear does not exceed 0.08mm, the spline cannot pass through the fixed ring 120. Conversely, when the spline passes through the fixed ring 120, it means that the wear of the spline exceeds the threshold of 0.08mm.

[0028] The slider 200 is slidably connected to the top of the base 100. A fixed platform 130 is installed on the top of the base 100. A guide groove 140 is opened on the top of the fixed platform 130. A slot 210 is opened on the top of the slider 200. A pull rod 220 is installed on the side wall of the slider 200. The slider 200 is located on the top of the fixed platform 130. A guide block 230 is installed on the bottom of the slider 200. The guide block 230 is slidably connected inside the guide groove 140. By pushing the pull rod 220, the slider 200 and the splint 300 are driven to move back and forth on the top of the base 100, and the splint 300 drives the input shaft of the differential reducer to move back and forth.

[0029] There are two clamping plates 300 and they are symmetrically located on the top of the slider 200. The differential reducer input shaft is clamped and fixed between the two clamping plates 300. The differential reducer input shaft is coaxial with the fixing ring 120, and the spline end of the differential reducer input shaft faces the fixing ring 120. The side wall of the slider 200 is rotatably connected with a knob 240. The side wall of the knob 240 is installed with a positive and negative threaded rod 250. The positive and negative threaded rod 250 extends into the interior of the slot 210. An extension plate 310 is installed at the bottom of the clamping plate 300. The extension plate 310 is located inside the slot 210. A threaded hole 320 is opened on the side wall of the extension plate 310. The positive and negative threaded rod 250 rotates through the threaded hole 320. A guide rod 2 is installed inside the slot 210. 60. A guide hole 330 is provided on the side wall of the extension plate 310, and the guide rod 260 passes through the guide hole 330. A rubber pad 340 is installed on the inner wall of the splint 300. By placing the input shaft of the differential reducer between the two splints 300, the rotating knob 240 drives the forward and reverse threaded rod 250 to rotate. When the forward and reverse threaded rod 250 rotates, the screw structure is used to push the two extension plates 310 to drive the two splints 300 to approach each other until the two splints 300 clamp the input shaft and fix the input shaft to be coaxial with the fixing ring 120, so that the slider 200 can drive the splint 300 and the input shaft to move in the direction of the fixing ring 120, and it is convenient to observe whether the spline can pass through the fixing ring 120.

In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
