In order to achieve a sufficient sealing effect, the dustproof sleeves at the two ends of the guide through hole are respectively connected with the end part of the guide sleeve and the bracket, so that external water cannot enter the dustproof sleeves.

Preferably, the axial two ends of the guide through hole are provided with dustproof sleeve positioning grooves, the end part of the dustproof sleeve is provided with a sealing snap ring, the sealing snap ring is clamped in the dustproof sleeve positioning grooves, and the inner ring of the sealing snap ring is in contact with the guide sleeve.

Preferably, a plurality of sealing convex strips are arranged on the outer side wall of the sealing snap ring side by side.

Preferably, one end of the guide sleeve is abutted against the bracket, and the other end of the guide sleeve is abutted against a gasket at one end of the guide bolt.

Compared with the prior art, the beneficial effects of the utility model are that:

the guide through hole has the advantages of simple structure, component saving, simplified installation process, improved sealing performance in the guide through hole and prolonged service life of products.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1-4, the utility model relates to a floating brake caliper of car, including pincers body 1 and support 4, pincers body 1 include extension 12 of main part 11 and main part 11 one side, main part 11 and extension 12 between form the brake groove, the brake groove install support 4, the inside both sides in brake groove install brake block 5.

As the working principle of the floating brake caliper, a piston is arranged in a main body 11, a brake pad 5 is arranged on the piston, liquid inlet pressure oil in the main body 11 can push the piston out, the brake pad 5 can push the caliper body 1 back after touching a brake disc due to the reaction force, and thus the brake pad 5 on the extension part 12 and the brake pad 5 on the piston can be clamped together to realize braking.

Because the clamp body 1 and the support 4 need to move relatively, two ends of the main body 11 are provided with guide through holes 6, guide bolts 2 with one ends connected with the support 4 penetrate through the guide through holes 6, guide sleeves 9 are sleeved on the outer sides of the guide bolts 2, a circle of guide bosses 7 are arranged in the middle of the inner sides of the guide through holes 6, the guide bosses 7 are tightly attached to the outer side walls of the guide sleeves 9, two ends of each guide through hole 6 are connected with dustproof sleeves 8, the guide bosses 7 replace the function of a bushing in the prior art, are integrally formed with the clamp body 1, play a role of guiding with the guide sleeves 9, and relatively reduce gaps between the guide through holes 6 and the guide sleeves 9.

The side wall of the dust-proof cover 8 is provided with a plurality of folds, so that the dust-proof cover 8 can be deformed.

In order to achieve a sufficient sealing effect, one ends of the dustproof sleeves 8 at the two ends of the guide through hole 6 are respectively connected with the end part of the guide sleeve 9 and the support 4, so that it is guaranteed that outside water cannot enter the dustproof sleeves 8, meanwhile, the two axial ends of the guide sleeve 9 are respectively provided with dustproof sleeve positioning grooves 13, the end part of the dustproof sleeve 8 is provided with a sealing snap ring 14, the sealing snap ring 14 is clamped in the dustproof sleeve positioning grooves 13, and the inner ring of the sealing snap ring is in contact with the guide sleeve 9.
