Abstract
The utility model discloses a brake drum of a heavy lorry, belonging to the technical field of heavy lorry braking. The section of the brake drum of heavy lorry is circle, which is characterized in that the peripheral surface of the brake drum is gully-shaped, and the section of the brake drum is gradually reduced from internal to external. The utility model is used for radiating when braking the heavy lorry and has the advantages of simple structure and easy use, which is profitable for radiating.
Description
(1) technical field under
The utility model relates to a kind of heavy-duty car brake drum, belongs to heavy-duty car braking technology field.
(2) background technique
Be widely used in heavy-duty car and link together with wheel bolt and wheel hub with brake drum, rotate with wheel hub, during braking, fixed brake shoe opens with brake drum friction-produced resistance to be braked with realization, simultaneously, and the heat that friction-produced is a large amount of.At present, heavy-duty car is circular with the brake drum cross section, and cross-sectional sizes is consistent from inside to outside, and promptly outer surface shape in alignment is unfavorable for heat radiation, when braking frequency is higher, makes brake drum overheated easily, and whole braking system is caused damage.
(3) summary of the invention
The utility model provides a kind of heavy-duty car brake drum that is beneficial to heat radiation in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of heavy-duty car brake drum, cross section are circular, and its special way is: described brake drum outer surface is the gully shape.
Heavy-duty car brake drum of the present utility model, it further improves and is: described brake drum cross section reduces from inside to outside successively.
The utility model has structurally increased heat diffusion area, is adopting non-directional structural type with wheel hub joint outer surface, and the structural type that increases the gully is beneficial to heat radiation with the surface area that increases brake drum; Simultaneously, the brake drum periphery reduces from inside to outside, helps outwards distributing of heat.
Therefore, heat radiation when the utility model is used for the heavy-duty car braking has advantage simple in structure, easy to use, that be beneficial to heat radiation.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 looks schematic representation for master of the present utility model;
Fig. 2 is a schematic side view of the present utility model.
Among the figure, 1 outer surface, 2 gullies, 3 screws.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment cross section is circular, and outer surface 1 is gully 2 shapes, has structurally increased heat diffusion area, is adopting non-directional structural type with wheel hub joint outer surface, and the structural type that increases gully 2 is beneficial to heat radiation with the surface area that increases brake drum; Simultaneously, brake drum outer surface 1 reduces from inside to outside, helps outwards distributing of heat.Brake drum passes screw 3 with wheel bolt and links together with wheel hub, rotates with wheel hub, and during braking, fixed brake shoe opens and the brake drum friction, produces surface friction drag to realize braking.
Claims (2)
1. heavy-duty car brake drum, cross section are circular, and it is characterized in that: described brake drum outer surface (1) is gully (a 2) shape.
2. heavy-duty car brake drum according to claim 1 is characterized in that: described brake drum cross section reduces from inside to outside successively.
