Problems solved by technology
like figure 1 As shown, the traditional brake bottom plate is designed with double-pin shaft holes, and there are two cylindrical parts b5 connected together. At the same time, the screw hole part 3 of the dust cover plate is circular. Such a design wastes raw materials and increases brake Base plate weight
In addition, QT450-10 grade material is selected for casting of the bottom plate, and without any special treatment, the material strength is low. It is necessary to strengthen the thickness of the bottom plate and the height of the U-shaped edge to ensure the strength of the bottom plate, which wastes materials and increases the weight of the bottom plate

Embodiment Construction
[0017] Such as figure 2 As shown, the lightweight brake base plate of the present invention mainly includes a base plate main body 1, a U-shaped edge 2 located on the outer edge of the base plate main body 1 and perpendicular to the base plate, and a screw hole part 3 on the outer side of the U-shaped edge 2 for drilling and installing a dust cover. And the cylindrical part a4 used for drilling the shaft hole of the roller and the cylindrical part b5 used for drilling the shaft hole of the pin which are respectively located at both ends of the bottom plate main body 1 .
[0018] The bottom plate main body 1 is a hollow ring, and the thickness is reduced from the original 15mm to 7mm. The height of the U-shaped side 2 is reduced from the original 48mm to 10mm. The cylindrical part b5 is a cylinder with a diameter of 57mm and a height of 45mm, and the brake base plate is designed with a single pin shaft hole, only one cylindrical part b5 is required, which reduces the loss of ...

Abstract
The invention discloses a light brake backing plate and a manufacturing process thereof. The innovation points are as follows: the brake backing plate is designed by adopting single pin shaft hole design; a dustproof plate hole support is designed into six independent screw lugs; a QT900-9 material is selected; heat treatment is carried out; the length of the materials is enhanced; and the thickness of the backing late and the height of a side plate are reduced. Through the scheme and process, the weight of the brake backing plate is lowered, the material loss and cost of the backing plate are saved; and meanwhile, the strength of the backing plate after being subjected to the heat treatment is improved, and the service life of the backing plate is prolonged.
Description
technical field [0001] The invention relates to a lightweight brake base plate and its manufacturing process, in particular to a lightweight brake base plate designed with a single pin shaft hole and subjected to heat treatment and its manufacturing process. Background technique [0002] The brake base plate is an important part of the brake and the support of all parts of the brake. Therefore, the quality of the base plate plays a decisive role in the operation of the brake. Such as figure 1 As shown, the traditional brake bottom plate is designed with double-pin shaft holes, and there are two cylindrical parts b5 connected together. At the same time, the screw hole part 3 of the dust cover plate is circular. Such a design wastes raw materials and increases brake The weight of the bottom plate. In addition, the material of QT450-10 grade is selected for casting of the bottom plate, and it has not undergone any special treatment. Contents of the invention [0003] The t...
