Abstract

The utility model discloses a sealing dustproof device for a disc brake air chamber. A dustproof sleeve is arranged on a pushing rod of the disc brake air chamber, and a dustproof sleeve is arranged at the joint of the pushing rod and a pincer body of the disc brake air chamber. The dustproof sleeve on one side of the air chamber is in clearance fit with the pushing rod of the disc brake air chamber, and the dustproof sleeve on one side of a disc brake is in clearance fit with a cavity formed between the air chamber and a countersunk hole in the pincer body. The sealing dustproof device has the advantage of achieving the sealing dustproof function of the joint position of the brake air chamber and the disc brake.

Description

The sealing dust-proof device of air chamber for disk type braker
Technical field
The utility model relates to the auto parts and components field, specifically the sealing dust-proof device of air chamber for a kind of disk type braker.
Background technique
Drum brake uses air chamber owing to directly not being connected with brake inside, thus not high to the sealing and dustproof performance requirement, only with simple rubber dust-proof pad, can meet the demands.Disk type braker air chamber push rod directly is connected with brake inside now, for protection disc type brake inside structure, must by the sealing and dustproof performance of air chamber, higher requirement be arranged to disk type braker.
The model utility content
The purpose of this utility model is exactly in order to address the above problem, and has proposed the sealing dust-proof device of a kind of disk type braker with air chamber, meets the sealing and dustproof requirement of disk type braker and air chamber thereof.
To achieve these goals, the utility model adopts following technological scheme:
The sealing dust-proof device of air chamber for a kind of disk type braker, be provided with dirt-proof boot at the push rod of disk type braker air chamber and disk type braker air chamber push rod and disk type braker caliper connecting place.
Described disk type braker caliper is provided with counterbore, between the wall of disk type braker air chamber and counterbore, forms cavity, and dirt-proof boot one end extruding is arranged in this cavity.
Described dirt-proof boot is arranged in described cavity by the seal arrangement interference fit.
Described dirt-proof boot adopts the seal arrangement interference fit to be connected with the braking air chamber push rod joint.
The beneficial effects of the utility model are: realized the sealing and dustproof function to brake chamber and disk type braker connection part.
The accompanying drawing explanation:
Fig. 1 is sectional arrangement drawing of the present utility model.
Fig. 2 a is the dust-proof cover structure partial sectional view that is positioned at disk type braker one side of the present utility model;
Fig. 2 b is the dust-proof cover structure partial sectional view that is positioned at air chamber one side of the present utility model;
Fig. 3 a is disk type braker caliper outline drawing;
Fig. 3 b is disk type braker caliper counter bore structure sectional view.
Wherein, 1. disk type braker caliper, 2. dirt-proof boot, 3. disk type braker air chamber, 4. braking air chamber push rod, 5. dirt-proof boot air chamber side structure, 6. dirt-proof boot disk type braker side structure, the 7. counter bore structure on the disk type braker caliper.
Embodiment:
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
As shown in Figure 1, Figure 2 and Figure 3, dirt-proof boot 2 is installed between disk type braker air chamber push rod 4 and disk type braker caliper 1.Wherein, on disk type braker caliper 1, be processed with counter bore structure, between the counter bore structure 7 on disk type braker air chamber 3 and disk type braker caliper 1, form cavity, dirt-proof boot disk type braker side structure 6 is extruded and is arranged in cavity; Dirt-proof boot air chamber side structure 5 disk type braker air chamber 3 inner with braking air chamber push rod 4 interference fit, the interference fit by air chamber dirt-proof boot 2 sealed at both ends devices realizes the sealing and dustproof function with disk type braker caliper 1 connection part to disk type braker air chamber 3.
Although above-mentioned, by reference to the accompanying drawings embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
