Abstract
The utility model discloses a kind of brake drum, comprise flange part, drum body, the root of drum body is connected with flange part, brake drum flange part arranges multiple bolt mounting holes, described brake drum is arranged on the mountion plate of wheel hub by bolt mounting holes, the curved position thickness L of described root is not less than 20mm, is provided with the heavy seat to root concavity at the inwall of described root, corresponding each bolt mounting holes.The utility model is by taking off the failure analysis of top product to brake drum, thicken the thickness of brake drum drum body root, substantially increase the mechanical strength of bulging body root, effectively can prevent flange part and fracture of root, take off catastrophe failures such as pushing up, improve vehicle safety and travelling comfort.
Description
Technical field
The utility model relates to trailer semitrailer component technical field, specifically, relates to a kind of brake drum.
Background technique
Brake drum is one of automobile important spare part, and it acts on automobile antero posterior axis, is not only the braking ability affecting automobile, and affects the degree of balance of wheel.The bulging shape of brake drum is peviform, and opening is arranged at top, and opening installs wheel hub, top and the drum body joint arc transition of brake drum.Usual wheel hub brake drum is bolted connection, and outside, wheel hub is interior for brake drum.If the connection place insufficient strength of brake drum and wheel hub, then easily occur that brake drum takes off the critical defect on top, more likely there is security incident in severe patient, causes heavy losses.And from fault sample analysis after sale, the phenomenon that assembling place of wheel hub brake drum takes off top is unrare.
Model utility content
The utility model object is the deficiency in order to solve the problems of the technologies described above, and provides a kind of reinforced brake drum, improves the stress structure of drum body weakness, improves bulk strength, to solve the problem that brake drum takes off top.
The technical solution of the utility model is: a kind of brake drum, comprise flange part, drum body, the root of drum body is connected with flange part, brake drum flange part arranges multiple bolt mounting holes, described brake drum is arranged on the mountion plate of wheel hub by bolt mounting holes, the curved position thickness L of described root is not less than 20mm, is provided with the heavy seat to root concavity at the inwall of described root, corresponding each bolt mounting holes.
The perpendicular wall of described heavy seat is arc, the perpendicular wall of heavy seat perpendicular to the horizontal plane of flange part, described heavy seat erect wall to the distance of bolt mounting holes and the external diameter of bolt installing sleeve suitable.
Compared with prior art, its beneficial effect is the utility model:
The utility model is by taking off the failure analysis of top product to brake drum, thicken the thickness of brake drum drum body root, substantially increase the mechanical strength of bulging body root, effectively can prevent flange part and fracture of root, take off catastrophe failures such as pushing up, improve vehicle safety and travelling comfort.
Conveniently wheel hub countersunk screw is installed, the corresponding each bolt mounting holes of brake drum drum body root is provided with the heavy seat to inner wall depression, to provide the installing space of countersunk screw, when the fastening installation of wheel hub drum bolt, the instruments such as bolt installing sleeve can be used very easily.

Embodiment
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the utility model, and can not being interpreted as restriction of the present utility model.
As shown in figures 1 to 6, brake drum of the present utility model, comprise flange part 2, drum body 1, the root 4 of drum body 1 is connected with flange part 2, brake drum flange part 2 arranges multiple bolt mounting holes 3, described brake drum is arranged on the mountion plate of wheel hub by bolt mounting holes, and the curved position thickness L of described root 4 is not less than 20mm, is equipped with the heavy seat 5 to root concavity at the inwall of root, corresponding each bolt mounting holes.The thick 14mm of existing brake drum root, the utility model thickeies design to drum body root, and the weak link that stress is concentrated well is improved.The utility model brake drum is through axletree stand test, and the result is desirable, reaches designing requirement.
The perpendicular wall 11 of heavy seat 5 is arcs, and the perpendicular wall 11 of heavy seat is perpendicular to the horizontal plane 10 of flange part, and the external diameter that heavy seat erects the distance of wall 11 to bolt mounting holes 3 and bolt installing sleeve is suitable.Therefore, when upper lock bolt, heavy seat provides the space that can be dodged bolt installing sleeve, to facilitate operative.And at the position of heavy seat, the curved position thickness H of root 4 also can reach 15mm, thicker than existing brake drum root.
Although illustrate and described embodiment of the present utility model; those of ordinary skill in the art is to be understood that: can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and aim; scope of the present utility model limited by claim and equivalent replacement thereof; in the improvement etc. done without creative work, all should be included within protection domain of the present utility model.
Claims (2)
