Abstract
An anti-crack drum brake comprises a drum brake body with two ends open, wherein an annular installation plate is arranged at one end of the drum brake body, an installation hole is formed in the annular installation plate, the drum brake body and the annular installation plate are formed integrally in a casting mode, a reinforcing annular plate is arranged at the position, close to the larger open end, of the surface of outer circumference of the drum brake body, and the inner wall of the reinforcing annular plate is in interference fit with the outer surface of the drum brake body. The anti-crack drum brake is reasonable in design and simple in structure. The reinforcing annular plate can prevent the drum brake from cracking due to thermal expansion under the condition of frequent braking, accidents are avoided, and the service life of the drum brake is prolonged.
Description
Technical field
The utility model belongs to automobile brake technical field, relates in particular to a kind of breaking-proof type brake drum.
Background technique
Braking system is one of important composition system of automobile chassis, particularly plays an important role at car load secure context.The braking device break overwhelming majority used now utilizes the friction of fixed element and rotatable member working surface to produce braking moment, can be divided into drum-type and disc type, domestic middle heavy Kapp is all over adopting drum-type, and overload is serious, in driving, the required braking force of brake drum is also large, especially at sharp turn, more severe to the test of brake drum when descending, easily there is cracking, watering the situation such as bursts and cause security incident.
Model utility content
The utility model, in order to solve deficiency of the prior art, provides a kind of durable, easy to crack, not safe and reliable breaking-proof type brake drum.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of breaking-proof type brake drum, comprise the brake drum body of open at both ends, one end of brake drum body is provided with annular mounting plate, annular mounting plate is provided with mounting hole, described brake drum body and the moulding of annular mounting plate integrally casting, brake drum body external peripheral surface is provided with enforced loop plane, enforced loop plane inwall and this external surface of brake drum interference fit closing on compared with big open end end place.
Described enforced loop plane is integrated by the riveted joint of rivet and brake drum body, and the outer surface soldering of rivet has with enforced loop plane outer surface and keeps smooth reinforcement plug, and the internal surface maintenance of the inner of rivet and brake drum body is smooth.
Adopt technique scheme, the outer round surface that the utility model closes on larger opening end at brake drum body is installed an enforced loop plane, the mode that adopts interference fit to embed between enforced loop plane and brake drum body, and carry out fastening with the reinforcement plug of rivet and soldering.
The utility model is reasonable in design, simple in structure, and heat expansion cracking when enforced loop plane can prevent that brake drum from frequently braking, avoids accident to occur, and extend the brake drum life-span.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of breaking-proof type brake drum of the present utility model, comprise the brake drum body 1 of open at both ends, one end of brake drum body 1 is provided with annular mounting plate 2, annular mounting plate 2 is provided with mounting hole 3, brake drum body 1 and annular mounting plate 2 integrally casting moulding, brake drum body 1 external peripheral surface is provided with enforced loop plane 4, enforced loop plane 4 inwalls and brake drum body 1 outer surface interference fit closing on compared with big open end end place.
Enforced loop plane 4 is integrated by rivet 5 and 1 riveted joint of brake drum body, and the outer surface soldering of rivet 5 has with enforced loop plane 4 outer surfaces and keeps smooth reinforcement plug 6, and the internal surface maintenance of the inner of rivet 5 and brake drum body 1 is smooth.
The utility model during fabrication, first adopts steel plate roll extrusion volume justify and make enforced loop plane 4 by splicing, re-uses the inner circle of lathe car enforced loop plane 4, then bores uniform riveted holes at circumference.Processing brake drum body 1, and the circumference of its larger opening end one side bore with enforced loop plane 4 on riveted holes riveted holes one to one.The enforced loop plane processing 4 is embedded to brake drum body 1, and brake drum body 1 adopts interference fit with enforced loop plane 4.
Brake drum body 1 material of the present utility model is cast iron, and enforced loop plane 4 is high tenacity steel, as 45 or 40Cr.Heat expansion cracking when the utility model steel plate can prevent that brake drum from frequently braking, avoids accident to occur, and extends the brake drum life-span.Brake drum body 1 and enforced loop plane 4 are riveted with rivet 5, and strengthen plug 6 in one of the rivet 5 hole place soldering of enforced loop plane 4 outer surfaces, brake drum body 1 is connected more fastening with enforced loop plane 4.
The present embodiment is not done any pro forma restriction to shape of the present utility model, material, structure etc.; any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all belong to the protection domain of technical solutions of the utility model.
