Definitions

  • the invention relates to an automobile brake drum, in particular to an automobile brake drum with an annular reinforcing rib.
  • the brake drums of automobile brake drums produced at home and abroad are mostly smooth outer surfaces, and some products have longitudinal ribs on the outer surface.
  • the brake drums of these structures have the following disadvantages:
  • the brake drum with smooth surface on the outside of the drum has poor heat dissipation performance, and the heat generated by the brake of the vehicle is slow, which causes the brake drum and the brake shoe to heat up rapidly, which reduces the friction coefficient and affects the braking effect.
  • the outer surface of the drum is not provided with reinforcing ribs, and the mechanical weight of the brake drum of the same weight or thickness is low, and the drum body is prone to fatigue cracking, thereby causing malfunction of the brake failure.
  • a brake drum provided with longitudinal ribs on the outer surface, although the heat dissipation area of the drum body is increased, it has no effect on reinforcing the mechanical strength of the drum body.
  • the longitudinal ribs 3 are parallel to the drum axis 4. Since the direction of the force of the brake drum is outwardly rounded from the inner surface of the workpiece, the resulting crack 5 is located between the longitudinal ribs 3, so the direction of the crack 5 is also substantially the same as the rib 3 (and The drum axis 4) is distributed in parallel, so the longitudinal ribs 3 do not function to increase the strength of the drum.
  • the object of the present invention is to overcome the deficiencies of the prior art and provide a novel automobile brake drum, which can obviously improve the strength and rigidity of the drum body, has better heat dissipation effect, ensures good braking performance, and improves driving safety performance.
  • the present invention provides a technical solution of the following: an automotive brake drum with an annular rib, comprising an automobile brake drum body, a plurality of rings arranged on the outer circumferential surface of the brake drum Reinforcement.
  • the direction of the force of the brake drum during operation is outwardly rounded from the inner circular surface of the workpiece, so that the direction of the broken crack 5 generated is also substantially parallel to the drum axis 4.
  • the annular reinforcing rib surrounds the surface of the drum body, is not parallel to the drum axis 4, and the annular reinforcing rib is a complete annular middle without an opening, the annular reinforcing rib can effectively increase the strength of the drum body, and can Prevent the generation of cracks 5 and the deformation of the drum.
  • the annular rib may also be perpendicular to the axis of the drum drum.
  • the drum body reinforcing effect is optimal.
  • the reinforcing ribs are integrally formed with the brake drum, and the number thereof is 1 to 10, preferably 3 ⁇
  • the rib cross section may be semicircular, triangular, trapezoidal or rectangular.
  • the invention Compared with the brake drum of the prior art, the invention has the following advantages: since there is an annular reinforcing rib on the outer circumferential surface of the brake drum of the automobile, not only the strength of the brake drum but also the rigidity can be obviously improved, and the heat is reduced. And the braking force acts to cause the brake drum to crack and deform, and maintain a good fit between the brake shoe and the brake drum. At the same time, it also increases the heat dissipation area of the brake drum, which can effectively reduce the brake drum temperature, reduce the heat impact on the steel shovel and the tire, improve the service life of the brake drum, the friction lining and the tire, and effectively prevent the brake. Accidents caused by cracked drums and tire punctures have improved the safety of driving. DRAWINGS
