Abstract
The utility model discloses a drum -type is dashed and is welded brake assembly, including the stopper body, two are the relative brake shoe that sets up of arc, and the braking bottom plate of setting at the brake shoe lower extreme, and set up in brake shoe upper end two sets of arc gusset arc gusset outside and, outer camber gusset outside is provided with the friction disc, the friction disc passes through rivet riveting fixed on the arc gusset, the rivet of less diameters such as rivet adoption 2.0mm or 2.5mm, at least through four rows of rivet riveting between friction disc and the arc board, the friction disc sets up to uniform thickness not according to the friction law, its friction disc outside is partially favored in inclined to one side internal friction piece, the rivet is for softening the iron rivet, braking bottom plate upper end is provided with the cam, the big S -shaped cam structure of protruding adoption, the utility model discloses having reduced the rivet diameter, having increased rivet quantity and reduced riveting power, improved the cohesion, S -shaped cam structure's design greatly, the thrust augmentation that makes brake chamber are more than 5%, and the cam lift strengthens, and the clearance adjustment number has significantly reduced.
Description
Technical field
The utility model relates to a kind of drum-type punching weldering brake assembly, belongs to vehicle brake field.
Background technique
Break is the important spare part of automobile, concerning vehicle performance and Security.The driving of current medium-heavy truck and steering axle break are nearly all the drum brakes based on casting material, to rush the drum brake of wlding material, in today that raw material and energy prices day rise, clearly, secondly the rivet diameter of friction plate and arc link of boards is excessive for the techno-economic effect of energy-saving consumption-reducing, number of rivets is very few, rivet force is too high, and combination force is not high, and, oeverall quality is too high, and interchangeability is poor.
Summary of the invention
For solving the problem, the utility model proposes a kind of drum-type punching weldering brake assembly.
A kind of drum-type punching weldering brake assembly, comprise break body, two curved brake shoes be oppositely arranged, and be arranged on the braking bottom board of brake shoe lower end, and be arranged on two groups of arc gussets and the outer arcuate gusset of brake shoe upper end, described outer camber gusset outer installment has friction plate, described friction plate is fixed on outer arcuate gusset by rivet, described rivet adopts the rivet of the small diameters such as 2.0mm or 2.5mm, at least rivet is arranged by four between described friction plate and outer camber gusset, described friction plate is set to not uniform thickness according to friction rule, its inclined outer friction sheet is comparatively thicker than inclined internal friction sheet, described rivet is softening iron rivet, described braking bottom board upper end is provided with cam, the large S-cam structure of described convex employing.
Further, described every block brake shoe with often to organize inner arc gusset and outer arc gusset and rush and weld formation one assembly welding component.
Further, described brake shoe and two pieces of arc gussets are drawing.
Further, described break body is provided with upper dust-proof cover and lower dust-proof cover by several bolt.
Further, described braking bottom board one end is provided with the backing pin connecting brake shoe, and the described brake shoe the other end and cam lean.
The utility model compared with prior art, it has following beneficial effect: drum-type punching weldering brake assembly of the present utility model, when coming into operation, during braking, cam driven brake shoe is that axle center expands outwardly and reaches braking effect with backing pin, the utility model reduces the rivet diameter connecting camber gusset and friction plate, increase number of rivets simultaneously, reduce rivet force, improve combination force, friction plate is designed to not uniform thickness friction plate according to its wear law, the utilization ratio of friction material is made to improve 20%, initial weight have dropped nearly 30%, softening iron rivet is adopted to replace non-ferrous metal to reduce the use amount of precious metal, energy saving, the oeverall quality of break is reduced while reducing costs, the design of large S-cam structure, the thrust of brake chamber is made to increase more than 5%, cam lift strengthens, greatly reduce gap adjustment number of times, the utility model achieves quality and alleviates, the advantage that performance and interchangeability improve, there are very large market prospects.
