Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a high-safety automobile drive disc. Background Art

[0002] The driving disc of an automobile automatic transmission is a component used to connect the crankshaft, the torque converter and the starter motor. Its main function is to transmit the engine torque and start the engine under the drive of the starter motor. Due to structural and functional requirements, some driving discs also need to be arranged with crankshaft position teeth on the driving disc so that the sensor can collect the crankshaft position signal. Since the driving disc is exposed to the outside, it is easy to be contaminated with dust and oil, causing corrosion and wear of the driving disc, and the safety is low. In order to ensure the safety of the driving disc, its exterior needs protective components. For example, patent announcement number CN216407672U discloses an automobile driving disc assembly. The solution is provided with a fixed disc on one side of the driving gear disc, and the driving gear disc is protected by the fixed disc, thereby achieving the effect of protection and reducing wear, and upgrading the safety of the entire driving disc. However, the fixed disc and the driving gear disc in the solution are fixed by bolts, and multiple bolts are provided. When in use, they are connected one by one by bolts, which is cumbersome to operate and wastes time and labor costs. The solution cannot quickly install and fix the fixed disc, so it needs to be improved. Utility Model Content

[0021] Example

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a high-safety automobile drive disc proposed in an embodiment of the utility model includes a driving gear disc 1 and a fixed disc 6, a connecting hole 11 is opened at the center of the driving gear disc 1, and a plurality of positioning rods 3 distributed in a ring array are fixedly connected to one side of the driving gear disc 1, positioning grooves 4 are opened on the positioning rods 3, and clearance holes 5 are opened at the corresponding positioning rods 3 of the fixed disc 6, the positioning rods 3 are adapted to the clearance holes 5 of the fixed disc 6, and the fixed disc 6 is provided with an annular groove 7 at the clearance hole 5, a swivel 8 is rotatably connected to the annular groove 7 of the fixed disc 6, and an array-distributed special-shaped positioning blocks 9 are fixedly connected to the swivel 8, and the special-shaped positioning blocks 9 are adapted to the positioning grooves 4 of the corresponding positioning rods 3.

[0023] It should be noted that the setting of the fixed plate 6 can realize the protection of one side of the driving gear plate 1, improve the safety of the use of the driving gear plate 1, avoid the wear of the driving gear plate 1, and then improve the safety level of the use of the driving gear plate 1, by arranging an array of positioning rods 3 on one side of the driving gear plate 1, and arranging a positioning groove 4 on the positioning rod 3, and extending the positioning rod 3 to the clearance hole 5 of the fixed plate 6 during assembly, at this time, the end of the positioning rod 3 is located at the annular groove 7 of the fixed plate 6, by rotating the connecting swivel 8 at the annular groove 7 of the fixed plate 6, and fixing the array-distributed special-shaped positioning block 9 on one side of the swivel 8, the special-shaped positioning block 9 is adapted to the positioning groove 4, when the positioning rod 3 is closed to the clearance hole 5 of the fixed plate 6, the swivel 8 is rotated, and then the special-shaped positioning block 9 is moved, and the special-shaped positioning block 9 extends to the positioning groove 4 corresponding to the positioning rod 3, thereby realizing the connection and fixation between the driving gear plate 1 and the fixed plate 6, which is convenient to operate and suitable for actual operation.

[0024] like Figure 1 and Figure 3 As shown, in some embodiments, one side of the special-shaped positioning block 9 is an arc-shaped surface, and the thickness of the special-shaped positioning block 9 is consistent with the height of the positioning groove 4.

[0025] It should be noted that one side of the special-shaped positioning block 9 is an arc-shaped surface, which is consistent with the contour of the positioning groove 4, so that the special-shaped positioning block 9 is adapted to the positioning groove 4. Then, when the swivel 8 is rotated, the special-shaped positioning block 9 can be tightly fitted in the positioning groove 4 of the positioning rod 3, realizing a locking connection between the structures with good tightness.

[0026] like Figure 1 As shown, in some embodiments, a washer 2 is provided at the connection between the driving gear plate 1 and the fixed plate 6 , and the washer 2 is sleeved on the positioning rod 3 .

[0027] It should be noted that there is a hole on the washer 2 that is compatible with the positioning rod 3, so that the washer 2 can be mounted on the positioning rod 3. During assembly, the washer 2 is located between the driving gear plate 1 and the fixed plate 6, which can reduce the hard contact between the driving gear plate 1 and the fixed plate 6, making the coordination between the structures more stable.
