Abstract
The utility model provides a drum brake shoe assembly structure for a heavy-duty car, which aims at solving the problems that the drum brake shoe assembly structure for the heavy-duty car in the prior art is large in weight of a brake shoe, high in manufacture cost, small in frication area and short in service life; the braking effect and the service life are influenced by large clearance between the brake shoe and a friction lining; and the like. The drum brake shoe assembly structure for the heavy-duty car comprises the braking shoe and the friction lining, wherein a welding type brake shoe replaces a casting type braking shoe; the width of the brake shoe is widened from 186mm to 221mm, and the width of the friction lining is widened from 185mm to 220mm. The number of riveting rivets in the middles of the brake shoe and the friction lining is increased from 16 to 28. The casting type brake shoe is the brake shoe machined through a casing mode, and the welding type brake shoe is the brake shoe processed machined through a welding mode.
Description
Invention field
The utility model relates to heavy-duty car with brake shoe for drum brake assembly technology, specially refers to heavy-duty car and uses the brake shoe for drum brake assembly structure.
Background technique
Heavy-duty car generally includes brake shoe and friction facing with the brake shoe for drum brake assembly, and adopts rivet that brake shoe and friction facing are riveted together.The existing technology heavy-duty car mostly adopts the mode of casting to process (abbreviating the founding type brake shoe as) with the brake shoe in the brake shoe for drum brake assembly, makes that the weight of brake shoe is bigger, and manufacturing process is complicated, and manufacture cost is higher, in the manufacture process environment is had pollution.In addition, the existing technology heavy-duty car uses the brake shoe width in the brake shoe for drum brake assembly to be 186mm, and the friction facing width is 185mm, makes that the friction area check and correction is less, and working life is shorter, and user cost is higher.Have again; The existing technology heavy-duty car is employed in edge symmetrical manner riveted joint with the brake shoe of brake shoe for drum brake assembly and the riveted joint rivet of friction facing; Total number of rivets is merely 16, makes that the gap between brake shoe and the friction facing is bigger, has influenced braking effect and working life.
Summary of the invention
For the weight that solves the brake shoe that the existing technology heavy-duty car exists with the brake shoe for drum brake assembly greatly, manufacture cost is higher; The friction area check and correction is less, and working life is shorter; Gap between brake shoe and the friction facing is bigger, has influenced problems such as braking effect and working life, and the utility model proposes a kind of heavy-duty car and uses the brake shoe for drum brake assembly structure.The utility model heavy-duty car is used the brake shoe for drum brake assembly structure, comprises brake shoe and friction facing, wherein, changes the founding type brake shoe into the welding type brake shoe; The brake shoe width dimensions is widened to 221mm from 186mm, the friction facing width dimensions is widened to 220mm from 185mm; And, make number of rivets be increased to 28 from 16 at brake shoe and friction facing middle part increase riveted joint rivet; Said founding type brake shoe is meant the brake shoe that the mode of employing casting is processed; Said welding type brake shoe is meant the brake shoe that the mode of employing welding is processed.
The utility model heavy-duty car is reliability and the serviceability that has improved brake shoe assembly with the useful technique effect of brake shoe for drum brake assembly structure; Reduced the brake shoe assembly manufacturing cost and use cost; Reduce brake shoe assembly weight, improved car load Economy and practicability.
Description of drawings
Accompanying drawing 1 is the schematic three dimensional views of existing technology heavy-duty car with the brake shoe for drum brake assembly;
Accompanying drawing 2 is existing technology heavy-duty car assembling schematic representation with the brake shoe for drum brake assembly;
Accompanying drawing 3 is the utility model heavy-duty car schematic three dimensional views with the brake shoe for drum brake assembly structure;
Accompanying drawing 4 is the utility model heavy-duty car assembling schematic representation with the brake shoe for drum brake assembly structure.
Below in conjunction with accompanying drawing and specific embodiment the utility model heavy-duty car is further described with the brake shoe for drum brake assembly structure.
Embodiment
Accompanying drawing 1 is the schematic three dimensional views of existing technology heavy-duty car with the brake shoe for drum brake assembly, and accompanying drawing 2 is existing technology heavy-duty car assembling schematic representation with the brake shoe for drum brake assembly, among the figure; 1 is brake shoe, and 2 is friction facing, and 3 is rivet; H is the friction facing width, and H is the brake shoe width.Can know that by figure heavy-duty car generally includes brake shoe 1 and friction facing 2 with the brake shoe for drum brake assembly, and adopt rivet 3 that brake shoe 1 and friction facing 2 are riveted together.The existing technology heavy-duty car mostly adopts the mode of casting to process (abbreviating the founding type brake shoe as) with the brake shoe in the brake shoe for drum brake assembly, makes that the weight of brake shoe is bigger, and manufacturing process is complicated, and manufacture cost is higher, in the manufacture process environment is had pollution.In addition, the existing technology heavy-duty car uses the brake shoe width H in the brake shoe for drum brake assembly to be 186mm, and friction facing width h is 185mm, makes that the friction area check and correction is less, and working life is shorter, and user cost is higher.Have again; The existing technology heavy-duty car is employed in edge symmetrical manner riveted joint with the brake shoe of brake shoe for drum brake assembly and the riveted joint rivet of friction facing; Total number of rivets is merely 16, makes that the gap between brake shoe and the friction facing is bigger, has influenced braking effect and working life.
Accompanying drawing 3 is the utility model heavy-duty car schematic three dimensional views with the brake shoe for drum brake assembly structure; Accompanying drawing 4 is the utility model heavy-duty car assembling schematic representation with the brake shoe for drum brake assembly structure, and among the figure, 1 is brake shoe; 2 is friction facing; 3 is rivet, and h is the friction facing width, and H is the brake shoe width.Can know that by figure the utility model heavy-duty car is used the brake shoe for drum brake assembly structure, comprise brake shoe 1 and friction facing 2, wherein, change the founding type brake shoe into the welding type brake shoe; Brake shoe width H size is widened to 221mm from 186mm, friction facing width h size is widened to 220mm from 185mm; And, make number of rivets be increased to 28 from 16 at brake shoe and friction facing middle part increase riveted joint rivet; Said founding type brake shoe is meant the brake shoe that the mode of employing casting is processed; Said welding type brake shoe is meant the brake shoe that the mode of employing welding is processed.Owing to adopt welding manner processing brake shoe can adopt rolling or forging steel plate welding processing brake shoe, make the brake shoe overall weight reduce, intensity increases, and rigidity increases, and has also reduced manufacture cost.Owing to increased the width of brake shoe and friction facing, make friction area obviously increase, improved braking effect, prolonged working life.Owing to increase the riveted joint rivet at brake shoe and friction facing middle part; Make number of rivets be increased to 28 from 16; Make brake shoe and friction facing link together closely, almost do not have a gap between brake shoe and the friction facing, improved braking effect and working life.Obviously, the utility model heavy-duty car is reliability and the serviceability that has improved brake shoe assembly with the useful technique effect of brake shoe for drum brake assembly structure; Reduced the brake shoe assembly manufacturing cost and use cost; Reduce brake shoe assembly weight, improved car load Economy and practicability.
