Description

Disk brake sliding device

Technical Field

The utility model relates to the technical field of brakes, in particular to a sliding device of a disc brake.

Background

At present, a disc brake on the market is generally a floating caliper, the caliper can slide on a support along a guide pin to realize braking, a sliding bearing is usually an inner cylindrical copper sleeve formed by die casting copper alloy, and a gap exists between the copper sleeve and the guide pin.

The lubricating grease content between the copper bush and the guide pin is low, dry friction is easy to generate, and in addition, due to the working condition that the brake is in impact and vibrates for a long time, pits are easy to generate in the copper bush, so that sliding is not smooth, the return of the brake is influenced, the service life of the brake is influenced, and secondly, due to the fact that gaps exist between the copper bush and the guide pin, noise of metal collision is easy to generate when a vehicle runs over a bumpy road surface, driving experience is influenced, and particularly comfort level of passengers of a city bus is influenced.

Disclosure of Invention

The utility model aims to solve the problems that in the prior art, pits are easily generated in a copper sleeve to cause unsmooth sliding, the return of a brake is influenced, the service life of the brake is influenced, metal collision noise is easily generated when a vehicle runs over a bumpy road surface, driving experience is influenced, and particularly the comfort level of passengers of an urban bus is influenced.

In order to achieve the above purpose, the present utility model adopts the following technical scheme: the utility model provides a disk brake slider, includes the pincers body, the front surface of the pincers body is embedded to be provided with slide bearing, slide bearing's outside is provided with the slide pin, slide pin's front surface through-connection has the screw, it has grease to fill between slide bearing and the slide pin, slide bearing's cross-section external diameter is the wave form.

Further, a bracket is arranged at the bottom of the clamp body.

Further, the screw is in threaded connection with the bracket.

Compared with the prior art, the utility model has the advantages and positive effects that,

1. according to the utility model, the corrugated shape of the sliding bearing of the sliding device provides more space for storing grease, so that dry friction is avoided, long-term smooth interaction of the caliper body is ensured, and the service life of the brake is prolonged.

2. In the utility model, the clearance between the sliding bearing and the sliding pin is close to 0, and the sliding bearing has good toughness, can effectively absorb vibration, reduce noise and improve the comfort of passengers of a driver.

Detailed Description

In order that the above objects, features and advantages of the utility model will be more clearly understood, a further description of the utility model will be rendered by reference to the appended drawings and examples. It should be noted that, without conflict, the embodiments of the present utility model and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, however, the present utility model may be practiced otherwise than as described herein, and therefore the present utility model is not limited to the specific embodiments of the disclosure that follow.

The embodiment, as shown in fig. 1-3, provides a disc brake sliding device as shown in fig. 1, which comprises a caliper body 1, wherein a sliding bearing 3 is embedded in the front surface of the caliper body 1, a sliding pin 4 is arranged outside the sliding bearing 3, a screw 5 is connected to the front surface of the sliding pin 4 in a penetrating manner, grease 6 is filled between the sliding bearing 3 and the sliding pin 4, the outer diameter of the section of the sliding bearing 3 is in a waveform shape, a bracket 2 is arranged at the bottom of the caliper body 1, and the screw 5 is in threaded connection with the bracket 2.

The whole embodiment of the device achieves the effects that the sliding bearing 3 is made of high-toughness wear-resistant material 65Mn steel, a gap between the sliding bearing 3 and the sliding pin 4 is close to 0, the sliding bearing 3 with a corrugated pipe shape is embedded in the clamp body 1 through fixing the sliding pin 4 on the support 2 through the screw 5, the clamp body 1 freely slides on the support 2 along the sliding pin 4, the sliding bearing 3 in the clamp body 1 is always in contact with the sliding pin 4, so that the sliding bearing 3 can effectively absorb vibration, a large amount of grease 6 can be stored in the gap due to the fact that the sliding bearing 3 is a corrugated pipe and is in clearance with the sliding pin 4, sliding smoothness can be kept, a new sliding device is adopted, the storage amount of the grease 6 between the sliding bearing 3 and the sliding pin 4 can be effectively increased, the gap between the sliding bearing 3 and the sliding pin 4 can be reduced, the high-toughness sliding bearing 3 is used, vibration noise can be effectively absorbed, the long-term reliability of sliding can be ensured, and the service life of a brake can be prolonged.

Working principle: the clamp body 1 freely slides along the sliding pin 4 on the support 2, the sliding bearing 3 inside the clamp body 1 is always in contact with the sliding pin 4, so that the sliding bearing 3 can effectively absorb vibration, a large amount of grease 6 can be stored in the gap because the sliding bearing 3 is a corrugated pipe and has a gap with the sliding pin 4, the sliding is smooth, the novel sliding device is adopted, the storage amount of the grease 6 between the sliding bearing 3 and the sliding pin 4 can be effectively increased, the gap between the sliding bearing 3 and the sliding pin 4 is reduced, and the sliding bearing 3 with high toughness is used to effectively absorb vibration to reduce noise, ensure long-term reliability of sliding and prolong the service life of a brake.
