Abstract
The utility model relates to a high-strength car brake drum structure which comprises body part, wherein a cast-steel sleeve is inlaid on the inner surface of the body part. Two hoopings are hooped on the outer surface of the body part. According to the high-strength car brake drum structure, through additional arrangement of the cast-steel sleeve and the hoopings, structural strength of a brake drum is greatly strengthened, the brake drum cannot easily crack, and the performance is safe and reliable.
Description
Technical field
The utility model relates to a kind of auto parts and components, is specifically related to a kind of high-strength automotive brake drum structure, belongs to the auto parts machinery technical field.
Background technique
Brake drum is the constituent elements of the drum brakes of automobile.When brake, by the inwall generation pressure of brake block to brake drum, produce friction by brake block and brake drum and stop rotation of wheel.
The brake drum of prior art adopts cast iron process to form mostly, and the structural strength of cast iron is relatively poor, causes the working life of brake drum shorter, and explosion easily occurs, and affects traffic safety, even accident.
Therefore, for avoiding above-mentioned technical problem, necessaryly provide a kind of structure improved high-strength automotive brake drum structure that has, to overcome described defective of the prior art.
The model utility content
For addressing the above problem, the purpose of this utility model is to provide a kind of structural strength high, is difficult for the high-strength automotive brake drum structure of explosion.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of high-strength automotive brake drum structure, and it comprises a main body portion, studs with a cast steel cover in the internal surface of described main body portion; Outer surface hoop in described main body portion is provided with two stirrups.
High-strength automotive brake drum structure of the present utility model further is set to: described main body portion is the main body portion of cast iron quality.
High-strength automotive brake drum structure of the present utility model also is set to: described main body portion and cast steel cover are interference fit.
Compared with prior art, the utlity model has following beneficial effect: high-strength automotive brake drum structure of the present utility model is overlapped and stirrup by setting up cast steel, thereby has greatly strengthened the structural strength of brake drum, makes it be difficult for explosion, and performance safety is reliable.
Description of drawings
Fig. 1 is the sectional drawing of high-strength automotive brake drum structure of the present utility model.
Embodiment
See also shown in Figure of description 1, the utility model is a kind of high-strength automotive brake drum structure, and it comprises a main body portion 1, and this main body portion 1 is the main body portion 1 of cast iron quality.
Internal surface in described main body portion 1 studs with a cast steel cover 2, thereby the wall thickness of brake drum is thickeied, and the pliability of cast steel is good, not easily broken.This main body portion 1 and cast steel cover 2 are interference fit, also can adopt other modes to fix.
Outer surface hoop in described main body portion 1 is provided with two stirrups 3.The number of described stirrup 3 also can increase and decrease as required.
High-strength automotive brake of the present utility model drum structure is by setting up cast steel cover 2 and stirrup 3, thereby greatly strengthened the structural strength of brake drum, makes it be difficult for explosion, and performance safety is reliable.
Above embodiment is only the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., within all should being included in the protection domain of this creation.
