Problems solved by technology

However, since only one center of the upper end of the friction block assembly in the above-mentioned utility model receives the thrust of the push plate, in this case, if the friction block assembly is worn out, uneven force will easily occur, which will not only make the friction block assembly It will wear out faster, and it will also weaken the braking effect. In addition, although the shaft assembly, needle roller pair, pressure arm and piston rod in the above-mentioned automobile air disc brake form a set of one-way rotation boosting mechanism, it can Adjust the excess gap between the assembly and the brake disc. Since there is no protection mechanism, when we adjust the excess gap, we may use too much force on the pressure arm, which will cause damage to the entire brake. Therefore, the above-mentioned car The structure of the air disc brake can be further improved

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] Such as Figure 1~6 A caliper disc brake shown includes a caliper bracket 1, a caliper body 2, a friction block assembly 3, an upper cover 4, and a pressure arm 5, and the upper cover 4 is connected with the caliper body 2. The caliper bracket 1 and the caliper body 2 are connected together by long bolts 24, short bolts 25, long guide sleeves 26, and short guide sleeves 27, and the long guide sleeves 26 and short guide sleeves 27 are inserted into the holes of the caliper body 2 to form bushings 28. Moving fit, the caliper body 2 slides axially relative to the caliper bracket 1 along the axis of the guide sleeve; the friction block assembly 3 on both sides of the brake disc 6 is pressed against the supporting surface of the caliper bracket 1 through two friction plate compression springs 7;

Abstract

This invention relates to one clamp disc brake, which comprises card clamp rack, card clamp part, friction bus, upper cover, pressure arm with other end fixed on the cover and rotation socket, wherein, the racket two sides have screw holes connected with screw bar with its down end through axis socket connected with pressure block; the block bottom and friction bus block surface are contacted together; the one screw bar has adjusting gap drive axis automatic structure; the other screw bar has adjusting gap passive axis structure bus connected through one simultaneous drive structure.

Description

technical field [0001] The invention relates to the technical field of automobile brakes, in particular to a caliper disc brake. Background technique [0002] Existing automobile brake has drum type and disc type two big classes, and power mode has the branch of hydraulic pressure and air pressure. Early automobile brakes were mainly drum-type. With the development of braking technology, disc brakes appeared. Because disc brakes have the advantages of fast heat dissipation, light weight, simple structure, and convenient adjustment, disc brakes have gained a lot of attention. Widely used, as a patent No. is ZL01212585.7 (announcement number is CN2468851Y) Chinese invention patent "automotive air pressure disc brake" discloses a kind of such structure, a kind of automobile air pressure disc brake, it is characterized in that brake is mainly made of The caliper bracket, caliper body, long guide bush, short guide bush, bush, pressure arm, shaft assembly, needle roller pair, sup...
