Abstract
The utility model discloses a braking base plate of a drum type brake, which comprises the following components: a base plate, a central mounting hole, a cam hole and supporting pin holes; wherein the central mounting hole, the cam hole and the supporting pin holes are arranged on the base plate. The cam hole is provided with a supporting shaft sleeve which is matched with the cam hole. The base plate is provided with a reinforcing plate in the axial direction of the supporting pin holes. The reinforcing plate is provided with through holes which are matched with the supporting pin holes. The outer edge of the base plate is fixedly connected with a dust shield fixing ring. According to the braking base plate of the drum type brake, a camshaft supporting shaft sleeve which is welded at the lower end of the base plate enlarges contact area of a braking camshaft, thereby reducing wearing to the cam hole. The dust shield fixing ring is welded on the back surface of the base plate for preventing splash of fine sands into the brake. A brake shoe supporting pin reinforcing plate is welded on the upper end of the base plate for improving supporting rigidity after assembling of the supporting pins.
Description
Technical field
The utility model belongs to the braking bottom board in automotive brake.
Background technique
Break is the important safety component of automobile, at present, domestic cargo vehicle break generally adopts drum-like brake structure, braking bottom board be in drum brake assembly except brake drum the installation matrix of each part, braking bottom board is bearing the break braking countertorque in when work, for guaranteeing that braking bottom board has enough rigidity, Current Domestic braking bottom board generally adopts casting technique to produce, foundry engieering is ripe, but casting technique is complicated, casting defect is many, and cost per unit is high, environmental pollution is large; At home, the less unit of this project carries out correlative study and test, main cause is that braking bottom board is as the installation matrix of each part of automotive brake, require the enough Rigidity and strengths of product tool, do not allow to lose efficacy, like this product structure and material have all been proposed to high requirement, simultaneously to welding process requirement also corresponding increasing.Abroad, due to the application of a large amount of new technologies and new material, rush welding structure braking bottom board technology more ripe, and assembled cargo vehicle in batches, manufacturing process has realized energy-saving and environmental protection.
Model utility content
The technical problems to be solved in the utility model is to provide that a kind of intensity is high, the drum brake braking bottom board of good dustproof effect.
In order to solve the problems of the technologies described above, the utility model provides a kind of drum brake braking bottom board, comprises base plate, and the center mounting hole on base plate, cam hole and support pin-and-hole, and cam hole is provided with the support sleeve coordinating with it; On base plate, along supporting pin-and-hole axial direction, be provided with stiffening plate, stiffening plate is provided with and the through hole that supports pin-and-hole and match; The outer rim of base plate is fixedly connected with dust-proof cover retaining ring.
Base plate in this scheme forms through cutting blanking, shaping flange, beading, and material adopts High Strength Low Alloy Steel plate, and thickness is 12mm; Camshaft support sleeve in the welding of base plate lower end increases brake camshaft area of contact, has reduced the wearing and tearing to cam hole; At base plate back side welding dust-proof cover retaining ring, be in order to prevent that tiny sandstone from splashing in break; At base plate upper end welding brake shoe anchor stiffening plate, to strengthen backing pin, assemble rear support rigidity.The utility model is rational in infrastructure, and strength and stiffness reach the technical requirements of same size casting base plate.Technique is simple, is easy to realize mechanization and produces in enormous quantities.Making full use of new material, new technology and new process is transformed tratitional technology.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the utility model embodiment's structural representation.
Fig. 2 is the utility model embodiment's semi-section schematic diagram.
Embodiment
As depicted in figs. 1 and 2, the utility model provides a kind of drum brake braking bottom board, comprises base plate 1, the center mounting hole 2 on base plate, and the cam hole 5 on base plate 1 and support pin-and-hole, cam hole 5 is provided with the support sleeve 6 coordinating with it; On base plate 1, along supporting pin-and-hole axial direction, be provided with stiffening plate 3, stiffening plate 3 is provided with and the through hole 7 that supports pin-and-hole and match; The outer rim of base plate 1 is fixedly connected with dust-proof cover retaining ring 4.
Base plate 1 in this scheme forms through cutting blanking, shaping flange, beading, and material adopts High Strength Low Alloy Steel plate, and thickness is 12mm; Camshaft support sleeve 6 in base plate 1 lower end welding increases brake camshaft area of contact, has reduced the wearing and tearing to cam hole 5; At base plate 1 back side welding dust-proof cover retaining ring 4, be in order to prevent that tiny sandstone from splashing in break; At base plate 1 upper end welding brake shoe anchor stiffening plate 3, to strengthen backing pin, assemble rear support rigidity.
Above-described is only preferred implementation of the present utility model, should be understood that for a person skilled in the art, not departing under the prerequisite of the utility model structure, can also make some distortion and improvement, these can not affect effect and practical applicability that the utility model is implemented.
