A press-fit dust cover for a brake disc

Abstract

The utility model relates to the field of automobile manufacturing, concretely relates to a press -fit type brake disc dust cover. Brake disc dust cover is provided with the central through -hole of interference fit with knuckle central boss, and the interference fit amount is 0.15-0.6mm, brake disc dust cover central through -hole and knuckle middle part boss are fixed by stamping press interference fit press -fit. Still be provided with the mounting position positioning hole on brake disc dust cover, with the corresponding setting of knuckle positioning bulge. Brake disc dust cover of the utility model and knuckle adopt interference fit assembly, distinguish with traditional bolt connection, can directly pass through mechanical press -fit, and efficiency is improved, and manpower cost is saved, and have very good stability.

Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, specifically to a press-fitted brake disc dust cover. Background Technology

[0002] The main function of an automotive braking system is to decelerate or even stop a moving vehicle, maintain a stable speed for a vehicle traveling downhill, and keep a stopped vehicle stationary (including on a slope). The automotive braking system directly affects the safety of driving and the reliability of stopping, making its research of significant importance. As a crucial component of the automotive braking system, the brake disc dust cover's main function is to isolate the brake disc from splashed sand, dirt, and other debris, while also preventing foreign objects from getting stuck between the brake disc and brake pads, thus avoiding damage to the braking system.

[0003] Traditionally, brake disc dust covers are fixed to steering knuckles with bolts, which involves a complex process and high labor costs. Utility Model Content

[0004] To solve the above problems, this utility model proposes a press-fit fixing method between the dust cover and the steering knuckle, realizing automated mechanized operation, greatly improving work efficiency and saving labor costs. The specific technical solution is as follows: A press-fitted brake disc dust cover, wherein the brake disc dust cover is provided with a central through hole that is interference-fitted with the central boss of the steering knuckle, the interference fit being 0.15-0.6mm; the central through hole of the brake disc dust cover and the central boss of the steering knuckle are press-fitted and fixed by a stamping machine.

[0005] Furthermore, the brake disc dust cover is also provided with mounting position positioning holes, which are corresponding to the positioning protrusions on the steering knuckle.

[0006] The brake disc dust cover of this utility model is assembled with the steering knuckle by interference fit, which is different from the traditional bolt connection. It can be directly mechanically pressed, which improves efficiency, saves labor costs, and has good stability performance. Attached Figure Description

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0010] like Figure 1-2 As shown, a press-fitted brake disc dust cover 1 is provided with a central through hole 12 that is interference-fitted with the central boss 21 of the steering knuckle 2, with an interference fit of 0.15-0.6mm. The central through hole of the brake disc dust cover and the central boss of the steering knuckle are press-fitted and fixed by a stamping machine. The brake disc dust cover is also provided with a mounting position positioning hole 11, which is correspondingly provided with a positioning protrusion on the steering knuckle.

[0011] During assembly, place the steering knuckle in the lower fixture of the press and the dust cover in the upper fixture (equipped with a magnet). Press the button to start the press. When the program detects that the stroke and force have reached the set values, stop the press. Use the button to separate the upper and lower fixtures. Remove the press-assembled part and place it on the product rack. This completes the assembly structure, as shown in the diagram. Figure 3 As shown in the figure. This utility model adopts mechanical pressing, which improves efficiency and saves labor costs.

[0012] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
