Technical Field
[0001] The utility model relates to the field of vehicle manufacturing, in particular to a coating protection plate for an intermediate shaft buffer disc. Background Art
[0002] The intermediate shaft of a vehicle is an important shaft in the car gearbox. The shaft itself is integrated with the gear. Its main function is to connect the first shaft and the second shaft, and select different gears to mesh with by changing the shift lever, so that the two shafts can output different speeds, directions and torques.
[0003] When the vehicle shifts gears, the switching of gears with different gear ratios will produce a certain gear shift shock, so the intermediate shaft needs to be equipped with a buffer structure during installation: Figure 1 As shown, the buffer structure usually adopts a rubber block, a bearing is installed in the inner hole of the rubber block, and the outer periphery is fixed in the intermediate support assembly.
[0004] The intermediate support assembly and bearings assembled on the outside of the buffer plate are steel parts, which need to be sprayed with protective paint to improve their rust resistance. Currently, the buffer plate is sprayed as a whole after assembly, which results in the rubber surface being painted. Furthermore, the organic solvents in the protective paint will cause certain corrosion to the rubber parts. On the other hand, since rubber products are elastic materials and the paint surface becomes a hard film after drying, paint peeling will occur after a period of time, affecting the appearance of the vehicle.

The paint protection plate designed in this scheme can be installed on one side surface of the buffer disk, and after the buffer disk and the intermediate support are assembled, it is embedded in the area enclosed by the intermediate support and blocks the exposed surface of the buffer disk. The bearing in the buffer disk is located in the circular hole, so that when the intermediate shaft support is sprayed, it can avoid being sprayed on the surface of the buffer disk, prevent corrosion of rubber parts, and improve aesthetics.
[0007] Preferably, a lap plate is provided on the edge of the first panel close to the second panel, the lap plate is located on the upper surface of the first panel, one side of the lap plate is fixedly connected to the first panel, and the other side of the lap plate protrudes from the edge of the first panel and extends above the second panel.
[0008] Preferably, the buffer tray connection structure comprises a plurality of connection pins, and the connection pins can be inserted into the weight-reducing holes of the buffer tray rubber block.
[0009] Preferably, the cross section of the connecting pin is an arc, the center of the arc is located at the center of the semicircular notch, and the arc length of the connecting pin is adapted to the length of the weight-reducing hole of the buffer disk rubber block. The connecting pin is more tightly connected to the buffer disk, and the installation positioning is achieved through the shape of the weight-reducing hole of the buffer disk.
[0010] Preferably, handles are provided on the upper surfaces of the first panel and the second panel.
[0011] Preferably, the handles are provided in plurality on the first panel and the second panel respectively, and the plurality of handles are arranged around the semicircular notch.
