刹车片能直接体现出制动效果的好坏,所以刹车片在汽车制动系统中是关键直接的部件。刹车片一般由地板、粘接隔热层和摩擦层构成,刹车片的隔热层是由热的不良传导材料及增强材料组成,刹车片的摩擦层是由增强材料、粘合剂及填料组成。一般采用液压传动于刹车钳的活塞推动刹车片和刹车盘或鼓接触磨擦转化为热能,从而达到减速制动的作用。
The brake pad can directly reflect the braking effect, so the brake pad is a key component in the automobile braking system. The brake pad is generally composed of floor, adhesive heat insulation layer and friction layer. The heat insulation layer of the brake pad is composed of poor heat conduction materials and reinforcing materials, and the friction layer of the brake pad is composed of reinforcing materials, adhesives and fillers. Generally, the piston hydraulically driven in the brake caliper is used to push the contact friction between the brake pad and the brake disc or drum into heat energy, so as to achieve the function of deceleration braking.
要检查所换刹车片是否是纯正配件,产品包装的完好性、防伪标志及包装标识与刹车片上的标识是否一致,产品型号是否和合格证内容相符。在将车辆举升这前,应先将盛放刹车油的覆盖打开,轮胎螺丝应对角松动。如果使用简易千斤顶支撑时,应将千斤顶支好,并加固不更换刹车片的轮子。将轮胎卸下,松开钳体紧固螺钉,并检查螺钉、钳滑动导杆,上面的泥沙及油污,并上润滑油保养。将旧刹车片拆下,检查刹车盘的磨损程度,是否起沟起糟。严重磨损应更换新的刹车盘,其周期为8—12万,否则会加快新更换的刹车片的磨损,且制动时方向抖动,制动力过校
First, check whether the replaced brake pad is a pure accessory, whether the integrity of the product packaging, anti-counterfeiting marks and packaging marks are consistent with the marks on the brake pad, and whether the product model is consistent with
the contents of the certificate. Before lifting the vehicle, open the cover containing brake oil and loosen the tire screws diagonally. If a simple jack is used for support, the jack shall be well supported and the wheels without replacing the brake pads shall be reinforced. Remove the tire, loosen the fastening screw of the tong body, check the screw and the sliding guide rod of the Tong, remove the sediment and oil stain on it, and apply lubricating oil for maintenance. Remove the old brake pad and check the wear degree of the brake disc for groove and mess. If the brake disc is seriously worn, it shall be replaced with a new one with a cycle of 80000-120000 km, otherwise the wear of the newly replaced brake pad will be accelerated, the direction will shake and the braking force will be over calibrated during braking
安装新刹车片应分清内外,刹车片的磨擦面应向刹车盘,使盘片配合合适。安好附件,紧固钳体。在紧固钳体前,应用工具将钳上的塞推回位,以便于将钳安装到位。如果需要更换鼓式制动器上的刹车片建议到维修厂请人员操作,以免出现差错。
When installing a new brake pad, the inside and outside shall be distinguished, and the friction surface of the brake pad shall face the brake disc to make the disc fit properly. Install the accessories and fasten the clamp body. Before tightening the tong body, push the plug on the Tong back with a tool to facilitate the installation of the Tong in place. If the brake pad on the drum brake needs to be replaced, it is recommended to go to the maintenance plant for operation to avoid errors.
