Description

Composite brake drum

Technical field:

The utility model relates to the technical field of components of medium and heavy trucks, in particular to a composite brake drum for medium and heavy trucks.

Background technique:

With the development of my country's automobile industry, medium and heavy-duty trucks have entered a period of rapid development. Domestic medium and heavy-duty trucks are developing towards high load capacity, high performance requirements and as long as possible warranty mileage; the integrated brake drum currently used There are the following disadvantages: 1. Insufficient rigidity and large thermal deformation; 2. High failure rate and short warranty mileage; 3. High maintenance costs for vehicles.

Invention content:

The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art, and provide a composite brake drum, which mainly solves the problems of insufficient rigidity, large thermal deformation, high failure rate and short warranty mileage of the existing one-piece brake drum.

In order to achieve the above purpose, the utility model is achieved in the following way: a composite brake drum, which includes a brake drum body, one end of the brake drum body is provided with a connecting steel ring, and its special feature is that it is placed outside the brake drum body There is an outer cover, the brake drum body is made of normal brake material HT250 alloy, the outer cover is made of low carbon steel plate, and the outer cover and brake drum body are combined in the form of casting or riveting. .

The utility model relates to a composite brake drum, wherein the brake drum body and the connecting steel ring can be integrated into one body; the outer skin is wavy, which can improve the heat dissipation performance.

Compared with the prior art, the composite brake drum described in the utility model has the following positive effects: 1. Adopting a composite form, the brake drum has strong rigidity and small thermal deformation; 2. The failure rate is low and the warranty mileage is low. 3. Reduce the cost of car maintenance.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is another structural schematic diagram of the utility model.

In order to better understand and implement, a composite brake drum of the present invention will be described in detail below in conjunction with the accompanying drawings to give specific embodiments.

Example 1, see Figure 1, the brake drum body 1 is made of normal brake material HT250 alloy, the brake drum body 1 is integrated with the connecting steel ring 2, and the outer surface of the brake drum body 1 is wrapped with a layer of low-carbon The cylindrical outer skin 3 rolled by steel plate is used to improve the rigidity of the brake drum. In order to improve the heat dissipation performance, the outer skin 3 is rolled into a wave shape, and the outer skin 3 and the brake drum body 1 are riveted in the form of casting or rivets. The form is combined into one.

Embodiment 2, referring to Fig. 2, adopts normal brake material HT250 alloy to make brake drum body 1, wraps a layer of cylindrical outer sheath 3 rolled with low-carbon steel plate on the outer surface of brake drum body 1, to improve the manufacturing efficiency. The rigidity of the moving drum, in order to improve the heat dissipation performance, the outer cover 3 is rolled into a wave shape, the outer cover 3 and the brake drum body 1 are combined in the form of casting or riveting, and finally at one end of the brake drum body 1 Install the connecting steel ring 2.

Claims (3)

1, a kind of combined type brake drum, it comprises brake drum body (1), and an end of brake drum body (1) is established and is connected steel ring (2), and its system is levied and is at brake drum body (1) peripheral hardware exoperidium (3).

2, a kind of combined type brake drum according to claim 1 is characterized in that described brake drum body (1) and is connected steel ring (2) and is integrated.
