Abstract
The invention discloses a split type brake drum. The brake drum is of a split structure and mainly comprises a drum cover and a drum ring, wherein the drum ring is in a cylindrical ring shape, the drum cover is in a circular mushroom shape, the bottom of the drum cover is horizontally folded towards the outer side, and the drum cover and the drum ring are positioned through a positioning pin and are fixedly connected through a bolt and a gasket. The invention greatly reduces the cost of the brake drum and can simultaneously ensure the performance requirement of the brake drum.
Description
Technical Field
The invention relates to a split type brake drum, in particular to a split type brake drum.
Background
Generally speaking, in the design of a general brake drum, the design of a brake drum material is single and is not very important, generally HT250 or HT225, the main processes of the two materials are casting, so that the cost is always high, the product performance is not reduced while the cost can be effectively reduced under the large prospect of high-speed development of automobiles, and the brake drum becomes a key legal standard whether automobile part manufacturers can stand out or not.
Therefore, it is necessary to design a new brake drum to replace the original brake drum.
Disclosure of Invention
In order to solve the problem that the material cost of the brake drum in the prior art is high, the invention aims to provide the split brake drum, the brake drum is divided into two parts, the drum ring is made of cast gray iron, the drum cover is made of steel materials of plate materials, the plate materials are formed into a cover-shaped structure through punch forming, so that the material cost is reduced, the punching cost is far lower than the casting cost, and meanwhile, the drum ring is made of gray iron metal materials to ensure relevant performance.
In order to achieve the purpose, the technical scheme of the invention is as follows:
the brake drum is of a split structure and mainly comprises a drum cover and a drum ring, wherein the drum ring is in a cylindrical ring shape, the drum cover is in a circular mushroom shape, the bottom of the drum cover is horizontally folded towards the outer side, and the drum cover and the drum ring are positioned through a positioning pin and are fixedly connected through a bolt and a gasket.
The peripheral edges of the drum cover and the drum ring are provided with a plurality of pin holes, and a plurality of positioning pins firstly pass through the pin holes on the drum cover and are inserted into the pin holes of the drum ring.
The positioning pin is in interference fit with the drum cover and the pin hole of the drum ring.
The peripheral edge of the drum cover is provided with a plurality of unthreaded holes, and a plurality of bolts penetrate through the unthreaded holes and are connected into the threaded holes of the drum rim in a threaded mode.
The drum ring material is composed of gray iron.
The drum cover material is composed of a metal steel plate.
The invention has the following beneficial effects:
the invention realizes the performance requirement of the brake drum, reduces the product cost, can improve the universality of the product by selecting and combining two sample pieces with different specifications, and saves the design and development cost.

FIG. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a sectional view a-a structural diagram of fig. 1.
Fig. 3 is a sectional view structural diagram of B-B of fig. 1.
Fig. 4 is an exploded view of the present invention.
In the figure: 1. the drum comprises a drum cover, 2 drum rings, 3 bolts, 4 gaskets and 5 positioning pins.
Detailed Description
The invention is further described with reference to the accompanying drawings and the detailed description.
As shown in fig. 4, the brake drum is a split structure, and mainly comprises a drum cover 1 and a drum ring 2, wherein the drum ring 2 is in a cylindrical ring shape, the drum cover 1 is in a round mushroom shape, the bottom of the drum cover is folded outwards, the drum cover 1 and the drum ring 2 are positioned by a positioning pin 5, and the drum cover 1 and the drum ring 2 are fastened and connected by a bolt 3 and a gasket 4.
As shown in fig. 1 and 3, the peripheral edges of the drum cover 1 and the drum rim 2 are provided with a plurality of pin holes, and a plurality of positioning pins 5 are inserted into the pin holes of the drum rim 2 through the pin holes on the drum cover 1.
The drum cover 1 and the drum ring 2 are positioned through the positioning pin 5, and the positioning pin 5 is in interference fit with pin holes of the drum cover 1 and the drum ring 2.
As shown in fig. 1 and 2, the peripheral edge of the drum cover 1 is provided with a plurality of unthreaded holes, a plurality of bolts 3 are threaded into the threaded holes of the drum rim 2 after passing through the respective unthreaded holes, and a washer 4 is arranged between the female end of the bolt 3 and the hole end face of the unthreaded hole of the drum cover 1.
The drum ring 2 is made of gray iron, and a plurality of threaded holes and a plurality of pin holes are formed in the joint of the drum ring 2 and the drum cover 1 on one side of the drum ring 2.
The drum cover 1 is made of metal steel plates, and a plurality of unthreaded holes and a plurality of pin holes are formed in the joint of the drum ring 2 and the drum cover 1 on one side of the drum cover 1.
Therefore, the structural design of the invention can greatly reduce the cost of the brake drum and simultaneously can ensure the performance requirement of the brake drum.
The above examples are illustrative of the present invention and are not intended to be limiting, and any simple modification of the present invention is within the scope of the present invention.
