Description
Technical Field
The utility model relates to an improvement invention in the field of automobile brake calipers, in particular to an improvement invention of a self-locking framework dust cover.
Background
The existing traditional skeleton dust cover mainly adopts an inner metal skeleton and an assembly body to ensure the assembly effect through press-in interference fit, and later-stage products are loosened, separated and the like due to the aging of vibration and the metal skeleton, so that water and dust enter a brake caliper in the use process, and the brake caliper is blocked and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art not enough, provide a simple to operate, the leakproofness is good from locking-type skeleton dust cover.
In order to solve the technical problem, the utility model discloses an adopt following technical scheme to realize: this kind of from locking-type skeleton dust cover, including the cover body, the internal skeleton that is equipped with of cover, its characterized in that: the brake caliper is characterized in that the cover body is of an annular structure, the inner circle of the cover body is provided with a sealing edge, the sealing edge is assembled in an annular groove on the outer peripheral surface of the piston, the outer circle of the cover body is provided with a self-locking lip edge, the self-locking lip edge is assembled in a groove of the brake caliper body, the outer side of the self-locking lip edge is provided with a barb, the side wall of the groove of the corresponding brake caliper body is provided with a step, and the step; a tensioning part is arranged between the sealing edge of the cover body and the self-locking lip edge, and the tensioning part is formed by bending and circuitous bending of the cover body.
The barb is provided with a guide inclined surface for guiding the self-locking lip edge into the groove.
The motion stroke of the sealing edge and the piston is less than 15 mm.
The beneficial effects of the utility model are that improve after, adopt to connect from locking-type for it is more convenient to install, and the leakproofness is good, solves the later stage because the ageing back-off problem that produces of vibration and metalwork.
Drawings
The following describes the present invention in further detail with reference to the accompanying drawings.
Fig. 1 is a structural view of the present invention assembled in a brake caliper body.
Fig. 2 is a schematic structural diagram of the present invention.
Detailed Description
The drawings show the structure of the present invention, and the details thereof will be further described with reference to the drawings. In the embodiment, the self-locking framework dust cover comprises a cover body 1, a framework is arranged in the cover body 1, the cover body 1 is of an annular structure, the inner circle of the cover body 1 is set to be a sealing edge 2, the sealing edge 2 is assembled in an annular groove 4 in the outer peripheral surface of a piston 3, the outer circle of the cover body 1 is set to be a self-locking lip edge 5, the self-locking lip edge 5 is assembled in a groove 7 of a brake caliper body 6, a barb 8 is arranged on the outer side of the self-locking lip edge 5, a step 11 is arranged on the side wall of the groove 7 of the corresponding brake caliper body 6, and the; a tensioning part 9 is arranged between the sealing edge 2 and the self-locking lip edge 5 of the cover body 1, the tensioning part 9 is formed by bending and circuitous bending of the cover body 1, the cover body is in a bow shape, contraction during assembly is achieved, and self-locking is achieved after the cover body is unfolded after assembly.
As a further improved specific embodiment, the barb 8 is provided with a guide inclined surface 10 for guiding the self-locking lip 5 into the groove 7, so that the installation convenience is improved.
As a further improved specific embodiment, the movement stroke of the sealing edge 2 and the piston 3 is less than 15mm, and the sealing performance is effectively ensured.
The utility model discloses an assembly process, with the cover body 1 in the interior round sealed side 2 pre-assembly to the ring channel 4 of piston 3, then with the assembled cover body 1 with the 3 piston 3 intracavity that impress the brake caliper body 6, and the auto-lock is accomplished in the auto-lock lip limit 5 of the cover body 1 excircle and the automatic packing of recess 7 on the brake caliper body 6 auto-lock, the step department of recess 7 is located to barb 8 hooks.
In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
