Description
Technical Field
The utility model relates to the automobile parts field is a dustproof, radiating strenghthened type brake drum.
Background
The automobile brake drum has compact structure, reliable performance and high power during braking, is a common brake device for large and medium automobiles, is generally called drum brake, forms brake efficiency through friction between a brake shoe and the brake drum, and bears extrusion stress on the inner surface of the brake drum due to the fact that a brake friction plate has high thrust on the inner surface of the brake drum when an automobile brakes.
Disclosure of Invention
The utility model aims at providing a dustproof, radiating strenghthened type brake drum. The strength and the rigidity of the brake drum can be ensured, and the dust is prevented from being brought into the brake drum in the running process of the automobile, so that the service life is prolonged, and the production cost is reduced.
The utility model discloses a realize like this: a dustproof and heat-dissipation reinforced brake drum is characterized in that a shaft hole is formed in the middle of a brake drum body, a circular surface is designed along the circumference of the brake drum body, reinforcing ribs and heat dissipation grooves are designed along the circumference of the inner layer of the circular surface, and an anti-rotation screw hole is designed in the brake drum body on the outer circle of the shaft hole; the brake drum is characterized in that a small end plane and a separation baffle are designed at one end of the brake drum body, a large end plane is designed at the other end of the brake drum body, a valve groove is designed at the upper end of the brake drum body, and a heat dissipation groove boss is designed at the lower end of the brake drum body.
Eight reinforcing ribs are uniformly distributed along the circumference.
The inner sides of the large end plane and the shaft hole are provided with dustproof grooves.
By adopting the technical scheme, the strength, the hardness and the friction coefficient of the brake drum are all in a stable state, and the strength is improved, the working capacity of high load is improved and the braking effect is ensured by adding the reinforcing ribs; the dustproof groove is added, and the dustproof effect is achieved.
Drawings
Fig. 1 is a schematic view of the structure of the present invention.
Fig. 2 is a left side view structure diagram of the present invention.
In the figure, 1, shaft hole; 2. a brake drum body; 3. reinforcing ribs; 4. a heat dissipation groove; 5. an anti-rotation screw hole; 6. a round surface; 7. a valve slot; 8. a small end plane; 9. separating the gear; 10. a heat dissipation groove boss; 11. a dust-proof groove; 12. a large end plane.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
In fig. 1 and 2, a shaft hole 1 is formed in the middle of a brake drum body 2, a circular surface 6 is designed along the circumference of the brake drum body 2, a reinforcing rib 3 and a heat dissipation groove 4 are designed along the circumference of the inner layer of the circular surface 6, and an anti-rotation screw hole 5 is designed on the brake drum body 2 at the outer circle of the shaft hole 1; the brake drum is characterized in that one end of the brake drum body 2 is provided with a small end plane 8 and a separation baffle 9, the other end of the brake drum body 2 is provided with a large end plane 12, the upper end of the brake drum body 2 is provided with a valve groove 7, and the lower end of the brake drum body 2 is provided with a heat dissipation groove boss 10.
Eight reinforcing ribs 3 are uniformly distributed along the circumference.
The inner sides of the large end plane 12 and the shaft hole 1 are provided with dust-proof grooves 11.
Eight reinforcing ribs 3 are added in the brake drum body 2 and are uniformly distributed, so that a balanced supporting effect is achieved; a plurality of radiating grooves 4 are added, so that a good radiating effect is achieved; 2 dustproof grooves 11 are additionally arranged on the large end plane 12, so that a good dustproof effect is achieved; and finally, connecting the brake shoe and the wheel hub by using a bolt through an anti-rotation bolt hole 5 and a bearing to form a brake system.
The intensity of brake drum, hardness and coefficient of friction all are in stable condition, through increasing the strengthening rib, the intensity is improved, the working ability of high load has been promoted, increase the dust proof tank, make the car at the operation in-process, the dust that the wheel rotation drove, direct isolated is in dust proof tank 11, can not influence the brake drum, the brake performance of brake drum has been promoted, the heat dissipation recess of increase, not only can improve the heat dissipation function, but also can guarantee the whole rigidity of brake drum, the valve groove 7 of increase, make the car when the operation, the heat that produces also can in time distribute away through the valve, brake efficiency has been guaranteed.
