Abstract
The utility model discloses a brake drum used for the heavy truck driving axle, which belongs to the technical field of the vehicle brake fitting manufacture. The brake drum comprises a drum body, and a reinforcement hoop is arranged on the surface of the drum body, the width of the reinforcement hoop is 60 to 80 mm, and the draft angle of the outer cylindrical surface of the drum is 4 to 4.5 degrees. The inner cylindrical surface of the drum is matched with a friction disc. Because the operating conditions of the brake drum are very bad, the brake drum is designed in order to improve the quality of the brake drum, and the rigidness and the thermal capacity can be improved. based on the improvement of the rigidness and the thermal capacity of the brake drum, the strength is enhanced and the heat emission is improved. Through the design, the diameter and the width of the reinforcement hoop are increased, simultaneously, the draft angle of the outer cylindrical surface is enlarged, and the thickness of the brake drum is increased, and thereby the weight of the brake drum is increased, and the brake drum has the advantages of reasonable structure, strong rigidness and good heat emission.
Description
Technical field
The utility model discloses a kind of heavy-duty car ransaxle brake drum, belongs to automobile brake accessory class manufacturing technology field.
Background technique
Brake drum is a strength member in the automobile brake system, service condition is very abominable, be subjected to powerful pressure of brake block and the comprehensive function of huge quiet or kinetic force of friction each other, occur failure modes such as cracking, crackle easily, operation brings influence to vehicle safety travel.
Summary of the invention
At the deficiencies in the prior art, the utility model provides that a kind of rational in infrastructure, rigidity is strong, the heavy-duty car ransaxle brake drum of good heat dissipation.
The utility model is achieved through the following technical solutions:
The utility model comprises bulging main body, and there is the hoop of reinforcement on the surface of drum main body, and wherein, the width of described reinforcement hoop is 60-80mm, and drum of outer cylinder draft angle is 4-4.5 °.
Described bulging inner cylindrical surface matches with friction plate.
The utility model is because the applying working condition of brake drum is very abominable, in order to improve the quality of brake drum, and designs this brake drum, improves its rigidity and thermal capacity.This brake drum is set about from improving rigidity and thermal capacity aspect, improves its intensity and improves distributing of heat.This design has strengthened the diameter and the width of the reinforcement hoop of brake drum, has strengthened the draft angle of outer conical surface simultaneously, and drum thickness increases, thereby has increased the weight of brake drum, has rational in infrastructure, advantages such as rigidity strong, good heat dissipation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein, 1, brake drum external cylindrical surface.2, strengthen hoop.3, brake drum inner cylindrical surface.
Embodiment
Embodiment: structure as shown in Figure 1, the utility model comprises bulging main body, the surface of drum main body has strengthens hoop 2, the width of strengthening hoop is 60-80mm, drum of outer cylinder draft angle is 4-4.5 °.Described bulging inner cylindrical surface matches with friction plate.Brake drum inner cylindrical surface 3 is subjected to the positive pressure and the frictional force of friction plate, makes brake drum generation distortion and produces a large amount of heats; Strengthen hoop 2 and widened behind the 20-30mm, rigidity strengthens, and brake drum is not yielding; Simultaneously, brake drum external cylindrical surface 1 draft angle increases to 4-4.5 °, and brake drum weight increases, thereby has improved the thermal capacity of brake drum, has improved heat dissipating state.
Claims (2)
1, heavy-duty car ransaxle brake drum comprises bulging main body, and there is the hoop of reinforcement on the surface of drum main body, and it is characterized in that: the width of described reinforcement hoop is 60-80mm, and drum of outer cylinder draft angle is 4-4.5 °.
2, heavy-duty car ransaxle brake drum according to claim 1, it is characterized in that: described bulging inner cylindrical surface matches with friction plate.
