Abstract
A reinforced brake drum relates to an accessory of motor vehicles, in particular to a vehicle brake drum. The reinforced brake drum is composed of a brake drum (1) and an outer hoop (2), the brake drum takes the shape of a bell jar and the outer hoop (2) is arranged on the outer wall of the brake drum (1). The reinforced brake drum overcomes the defect that the brake drum belongs to fragile steel products and is crackly, reinforces the strength of the brake drum, prolongs the service life of the brake drum, reduces the possibility that the brake drum is imploded when being under a high-temperature high-heat environment for a long time and offers uniform heat dissipation. The reinforced brake drum has simple process due to one time of cast molding.
Description
Technical field
The utility model relates to a kind of motor vehicle fittings, particularly a kind of brake drum for automobile.
Background technique
Present automobile brake drum is foundry goods sheerly, because foundry goods itself belongs to the fragility steel and easily breaks, at climb and fall or some dangerous area road travelings, when taking emergency braking, brake drum generates heat easily, and under the long high thermal environment of high temperature, brake drum is easily because of overheated explosion, cause the brake system failure of automobile, lead to the traffic accident accident.Application number is that 200820081147.8 utility model patent discloses " a kind of brake drum ", the disclosed brake drum for automobile of this model utility, brake drum and stiffening rib constitute, and brake drum is a bell shape, stiffening rib is circular reinforcing bar, be positioned at the bulging wall of brake drum opening end, stiffening rib can adopt the 1-5 root to be arranged in parallel as required, the utility model one-time cast-forming, technology is simple, is easy to manufacture control, can guarantee the better quality of brake drum.But because stiffening rib is positioned at the bulging wall of brake drum opening end, one-time cast-forming will guarantee that neutral position that stiffening rib is positioned at bulging wall just can reach the purpose of reinforcement, difficult grasp on the technology.
Summary of the invention
The purpose of this utility model is intended to overcome the defective of prior art, provides a kind of technology simple a kind of reinforcement brake drum.
Reinforcement brake drum described in the utility model is made of brake drum and outer hoop, and brake drum is a bell shape, is characterised in that, outer hoop is positioned at the external drum wall of brake drum.
There is stiffening rib in the outer hoop outside of described brake drum.
In the bulging wall of described brake drum stiffening rib is arranged.Stiffening rib is the 1-5 root.
Reinforcement brake drum described in the utility model, described outer hoop is gone up porose.
The outer hoop of reinforcement brake drum described in the utility model is positioned at the outer wall of brake drum, make the intensity of brake drum be improved, on the hoop aperture is arranged outside simultaneously, being used to solve material is meeting thermal expansion, is meeting cold contraction and the problem on deformation that causes, and can quicken the brake drum heat radiation, in addition, can also the inwall of brake drum or outside the arranged outside stiffening rib of hoop, further improved the intensity of brake drum, also can have aperture on the stiffening rib in the hoop outside outside according to the expansion coefficient of material, play the effect of heat radiation, improve the rate of cooling of brake drum.The utility model has overcome brake drum itself and has belonged to the defective that the fragility steel easily break, and has strengthened the intensity of brake drum, has improved the working life of brake drum, has reduced the brake drum possibility of explosion under the high thermal environment of high temperature for a long time, and heat radiation evenly.The utility model one-time cast-forming, technology is simple.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described, but is not limited to embodiment.
Reinforcement brake drum described in the utility model is made of brake drum 1 and outer hoop 2 as shown in Figure 1, and brake drum 1 is a bell shape, binds round the 2 external drum walls that are positioned at brake drum 1 outward.
A kind of reinforcement brake drum as shown in Figure 2, be to strengthen the intensity of brake drum, brake drum 1 outer hoop 2 outsides stiffening rib 3 is arranged, all the other are with embodiment 1.
As shown in Figure 3, be distributed with several holes 4 on the outer hoop 2 of reinforcement brake drum and the stiffening rib 3, stiffening rib 3 is 2 and is arranged in parallel that all the other are with embodiment 2.
As shown in Figure 4, be distributed with several holes 4 on the outer hoop 2 of reinforcement brake drum, stiffening rib 3 is 2 and is arranged in parallel, is positioned at the bulging wall of brake drum 1.
Embodiment 5
Stiffening rib is 5 and is arranged in parallel that all the other are with embodiment 4.
