Description
技术领域 technical field
本发明涉及一种汽车刹车片，属于汽车配件技术领域。 The invention relates to an automobile brake pad, which belongs to the technical field of automobile accessories.
背景技术 Background technique
汽车刹车片也叫汽车刹车皮，是指固定在与车轮旋转的制动鼓或制动盘上的摩擦材料，其中的摩擦衬片及摩擦衬块承受外来压力产生摩擦作用，从而达到促使车辆减速的目的。 Automobile brake pads, also called automobile brake pads, refer to the friction material fixed on the brake drum or brake disc that rotates with the wheel. The friction lining and friction pad in it are subjected to external pressure to generate friction, so as to promote the deceleration of the vehicle. the goal of.
汽车刹车片一般由钢板、粘接隔热层和摩擦块构成，钢板要经过涂装来防锈，涂装过程用SMT-4炉温跟踪仪来检测涂装过程的温度分布来保证质量；隔热层是由不传热的材料组成，目的是隔热；摩擦块由摩擦材料、粘合剂组成，刹车时被挤压在刹车盘或刹车鼓上产生摩擦，从而达到车辆减速和制动的目地。 Automobile brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. The steel plates must be coated to prevent rust. During the coating process, SMT-4 furnace temperature tracker is used to detect the temperature distribution of the coating process to ensure the quality; The heat layer is composed of non-heat-conducting materials for heat insulation; the friction block is composed of friction materials and adhesives, which are squeezed on the brake disc or brake drum to generate friction during braking, so as to achieve the effect of vehicle deceleration and braking. Purpose.
刹车的工作原理主要是来自摩擦，利用刹车片与刹车碟（鼓）及轮胎与地面的摩擦，将车辆行进的动能转换成摩擦后的热能，使车子停下来。一套良好有效率的刹车系统必须能提供稳定、足够、可控制的刹车力，并且具有良好的液压传递及散热能力，以确保驾驶人从刹车踏板所施的力能够充分有效的传到总泵及各分泵，从而避免高热所导致的液压失效及刹车衰退。 The working principle of the brake is mainly from friction, using the friction between the brake pad and the brake disc (drum) and the tire and the ground to convert the kinetic energy of the vehicle into the heat energy after friction to stop the car. A good and efficient braking system must be able to provide stable, sufficient and controllable braking force, and have good hydraulic transmission and heat dissipation capabilities, so as to ensure that the force exerted by the driver from the brake pedal can be fully and effectively transmitted to the master cylinder And each cylinder, so as to avoid hydraulic failure and brake failure caused by high heat.
现有刹车片摩擦层一般为平面结构，摩擦片与隔热片之间通过压合粘结在一起，由于摩擦过程中产生的热量会使摩擦层发热导致摩擦片变形，影响刹车性能；同时随着温度的升高，摩擦片与隔热片之间粘合剂的使用寿命随之降低，导致摩擦片在强受力过程中容易脱落，严重影响行车安全。现有摩擦片使用一段时间后，会逐渐变薄，如果不及时更换容易发生交通事故，因此厂家多通过专用规矩如游标卡尺等来测量其厚度，以此决定该刹车片是否报废，但该过程操作麻烦，费时费力，导致生产成本增加。 The friction layer of the existing brake pads is generally a flat structure, and the friction pad and the heat shield are bonded together by pressing. The heat generated during the friction process will cause the friction layer to heat up, causing the friction pad to deform and affect the braking performance; As the temperature rises, the service life of the adhesive between the friction plate and the heat shield decreases, causing the friction plate to fall off easily during strong stress, seriously affecting driving safety. The existing friction pads will gradually become thinner after being used for a period of time. If they are not replaced in time, traffic accidents will easily occur. Therefore, manufacturers usually use special rules such as vernier calipers to measure their thickness to determine whether the brake pads are scrapped. Troublesome, time-consuming and labor-intensive, resulting in increased production costs.

为此，本发明的技术方案为：一种汽车刹车片，包括钢片、隔热层、摩擦片，摩擦片粘合在隔热层上，隔热层固定在钢片上，其特征在于：摩擦片与隔热层连接处分别为相互对应的凸凹交替的齿状结构；在摩擦片上部设有排屑槽，在摩擦片下部贯穿于摩擦片两侧设有散热孔。 For this reason, the technical scheme of the present invention is: a kind of automobile brake pad, comprises steel sheet, heat insulation layer, friction sheet, and friction sheet is bonded on the heat insulation layer, and heat insulation layer is fixed on the steel sheet, is characterized in that: friction The connection between the sheet and the heat insulation layer is a tooth-like structure with alternating convex and concave corresponding to each other; chip removal grooves are provided on the upper part of the friction sheet, and cooling holes are provided on both sides of the friction sheet at the lower part of the friction sheet.
对于上述技术方案的一种改进在于：在所述摩擦片与隔热层之间压合有防震片，以有效降低刹车噪音。 An improvement to the above technical solution is that: a shockproof sheet is pressed between the friction sheet and the heat insulation layer to effectively reduce brake noise.
对于上述技术方案的进一步改进在于：在所述摩擦片一侧设有厚度警戒线，以方便判断是否需要更换刹车片。 A further improvement to the above technical solution is that a thickness warning line is provided on one side of the friction plate to facilitate judging whether the brake plate needs to be replaced.
