Description

[Technical field]

[0001] The utility model relates to the technical field of brake pads, in particular to the technical field of wear-resistant water tank brake pads. [Background technology]

[0002] Brake pads are also called brake leathers. In the braking system of a car, brake pads are the most critical safety parts. The quality of all braking effects is determined by brake pads. Therefore, good brake pads are the protectors of people and cars. The working principle of brakes mainly comes from friction. The friction between brake pads and brake discs and between tires and the ground is used to convert the kinetic energy of the vehicle into heat energy after friction to stop the car. A good and efficient brake system must be able to provide stable, sufficient and controllable braking force, and have good hydraulic transmission and heat dissipation capabilities to ensure that the force applied by the driver from the brake pedal can be fully and effectively transmitted. To the master pump and each sub-pump, and avoid hydraulic failure and brake degradation caused by high heat. At present, in order to strengthen the management of trucks and dangerous goods transport vehicles, and prevent and curb the occurrence of problems such as spillage, mud driving, and dust pollution by trucks and dangerous goods transport vehicles when leaving the construction site, trucks and dangerous goods transport vehicles must pass through a water trough when leaving the construction site. The water trough is mainly used to wash the dirt and debris wrapped around the tires of trucks and dangerous goods transport vehicles to prevent them from polluting the road surface. However, after the vehicle passes through the water trough, a large amount of sand and gravel will enter the vicinity of the brake pads, which greatly reduces the life of the brake pads and requires more frequent replacement of brake pads.

[0003] To solve the problems raised in the background technology, publication number CN218266939U discloses a brake pad for engineering vehicles passing through water troughs, wherein the brake pad body is provided with through heat dissipation holes, and the brake pad body is composed of an arc bottom plate, an adhesive layer, a heat insulation and sound insulation layer, and an arc friction layer from top to bottom, and the cross-sections of the arc bottom plate, the adhesive layer, the heat insulation and sound insulation layer, and the arc friction layer are all fan-shaped, and a waterproof layer is provided above the arc bottom plate, which has the effect of heat dissipation, heat insulation, and sound insulation, and a new friction surface is added to increase the friction force, and the arc friction layer is made of phenolic resin, which has high toughness, good flexibility, better wear resistance, and excellent crack resistance. However, this structure still has the following shortcomings:

[0004] 1. Although the brake pad uses an arc-shaped friction layer to improve wear resistance, it lacks a structure for discharging powder debris. Therefore, the powder debris generated during the friction between the brake pad and the brake disc cannot be discharged quickly, which can easily cause damage to the entire brake pad and affect its service life.

[0005] 2. The structure lacks reinforcement. Therefore, when the brake pad is affected by vibration during long-term use, it will be deformed and damaged, increasing the replacement cost. [Contents of the utility model]

[0006] The purpose of the utility model is to solve the problems in the prior art and to provide a wear-resistant water groove brake pad, which can quickly discharge powder debris generated by friction through the cross groove to avoid damage to the brake pad as a whole and has strong wear resistance and firmness.

[0007] To achieve the above-mentioned purpose, the utility model proposes a wear-resistant water groove brake pad, comprising a brake pad body, a cross groove, a first wear-resistant layer, a second wear-resistant layer, and a heat dissipation structure, wherein the brake pad body is in an arc-shaped structure, and a cross groove is provided on the upper end surface of the brake pad body, and the cross grooves extend to the edges of the brake pad body respectively, the upper surface of the brake pad body is provided with a first wear-resistant layer, the lower surface of the brake pad body is provided with a second wear-resistant layer, and the heat dissipation structure is provided at the center position of the lower end surface of the brake pad body.

[0008] Preferably, a buffer spring is symmetrically arranged on the lower end surface of the brake pad body, and the buffer spring is used to keep the brake pad body subjected to a smooth force and absorb vibration force.

[0009] Preferably, both the first wear-resistant layer and the second wear-resistant layer are made of low-alloy high-strength steel wear-resistant plates.

[0010] Preferably, the heat dissipation structure includes a groove, a heat dissipation pipe, and a heat dissipation hole. A circular groove is provided at the center of the lower end surface of the brake pad body, a heat dissipation pipe is embedded in the interior of the groove, and heat dissipation holes are symmetrically provided on the outer wall of the brake pad body, and the heat dissipation holes are connected to the heat dissipation pipe.

[0011] Preferably, a dustproof net is installed on the outer surface of the heat dissipation hole by bolts, and the dustproof net is a metal stainless steel dustproof net.

[0012] Preferably, a fixing threaded rod is provided at each of the four corners of the brake pad body, a fixing plate is sleeved on the fixing threaded rod, a fixing bolt is provided at the upper end of the fixing plate, and the fixing bolt is rotatably provided on the outer wall of the fixing threaded rod.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model has a cross groove on the upper end surface of the brake pad body. The cross groove helps to quickly discharge powder debris generated during the friction between the brake pad and the brake disc, prevents the debris from adhering between the brake pad and the brake disc, thereby avoiding scratches on the entire brake pad and maintaining the reliability of the braking effect. The design of the cross groove can also reduce the noise level during braking, accelerate air circulation, help the heat generated by friction to dissipate faster, ensure the effectiveness and safety of the braking system, and solve the problem that the brake pad cannot quickly discharge powder debris, causing damage to the entire brake pad.

The first wear-resistant layer and the second wear-resistant layer can protect the outer surface of the brake pad body and extend the service life of the brake pad body. The buffer retaining spring can balance the force of the brake pad body and absorb part of the vibration force to avoid deformation of the brake pad body after long-term use, thereby improving the strength of the brake pad body. Installing the fixing bolt on the fixed threaded rod can increase the firmness of the brake pad body and avoid cracking after long-term use, thereby solving the problem of deformation and damage of the brake pad caused by vibration during long-term use.
