Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The specific implementation mode is as follows: shown in connection with fig. 1-3, includes a brake hub 1; a mounting surface 101 is arranged on one side of the outer part of the brake hub 1; a plurality of groups of mounting holes 102 are uniformly formed in the upper part of the mounting surface 101; a reinforcing surface 103 is arranged on the other side of the outside of the brake hub 1; plate-shaped reinforcing ribs 104 are uniformly arranged at the upper part of the reinforcing surface 103; a braking surface 2 is arranged inside the brake hub 1; the periphery of the upper part of the braking surface 2 is uniformly provided with annular clamping grooves 201; a heat dissipation groove 202 is formed in the annular clamping groove 201; the heat dissipation groove 202 is internally provided with heat dissipation paste 203; the annular clamping groove 201 and the heat dissipation groove 202 are both trapezoidal; a friction plate 204 is arranged in the annular clamping groove 201; the two sides of the friction plate 204 are clamped with the annular clamping groove 201; an arc-shaped through groove 205 is formed in the friction plate 204; a dirt storage groove 206 is arranged between the annular clamping grooves 201 on the upper periphery of the braking surface 2; the dirt storage tank 206 is U-shaped.
When the brake is used, as shown in fig. 1, when a user drives a heavy-duty truck, a drum brake is usually selected because the drum brake has an automatic braking function, the drum brake is low in manufacturing cost and relatively convenient to maintain, but the conventional drum brake often has the condition that the brake hub 1 cracks under the condition of normal wear or slight wear, so that the driving safety is seriously affected, and therefore, the user can select the high-reliability brake hub for the heavy-duty truck, so that the problem is solved;
step two, as shown in fig. 2-3, in the use process of the conventional brake hub 1, the mounting surface 101 is easily subjected to transverse crack, so that the mounting surface 101 falls off, and the brake hub 1 fails, therefore, the brake hub 1 produced by the present invention is uniformly provided with the plate-shaped reinforcing ribs 104 between the reinforcing surface 103 and the mounting surface 101, the strength of the mounting surface 101 is enhanced by the plate-shaped reinforcing ribs 104, and the situation that the mounting surface 101 falls off is prevented, and in the interior of the brake hub 1, because the conventional brake hub 1 directly contacts with the brake pad to realize braking, the heat accumulation on the inner surface of the brake hub 1 is too much, so that the braking effect is reduced, and in the exterior of the brake hub 1, a water spraying cooling method is adopted, which further causes the brake drum in a high temperature state to generate cash, so that the situation of cracking failure occurs, the brake drum is internally provided with an annular clamping groove 201, the friction plates 204 are clamped in the annular clamping groove 201, and are contacted with a brake plate through a plurality of groups of friction plates 204 so as to brake, at the moment, the friction plates 204 can generate a large amount of heat, the heat dissipation paste 203 is arranged in the heat dissipation groove 202, the heat of the friction plates 204 is quickly absorbed through the heat dissipation paste 203, so that the friction plates 204 are kept at a lower temperature, the braking effect cannot be influenced, and after the friction plates 204 are heated, the friction plates 204 can generate certain deformation and have larger volume, at the moment, because the arc-shaped through grooves 205 are arranged in the friction plates 204, certain space is reserved for the deformation of the friction plates 204, the friction plates 204 are prevented from damaging the brake hub 1 per se, and along with the use of the brake hub 1, the friction plates 204 and the brake plate can be abraded, be provided with dirty groove 206 of storage between ring groove 201, hold powdered impurity, at this moment because brake hub 1 itself does not with braking piece between the direct contact, its upper portion temperature is lower, when using the water spray cooling, can not destroy brake hub 1's metallographic structure itself, promoted driving safety.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention.
