Abstract
The utility model relates to a drum-type brake drum of a semitrailer rear axle. The drum-type brake drum comprises a flange surface used for being matched with a hub. The drum-type brake drum is characterized in that a plurality of bolt holes are evenly distributed in the flange surface at equal distance, the flange surface is connected with a thickened Z-shaped brake surface, and the brake surface is provided with a plurality of reinforcing ribs which are used for increasing the stress area, improving the durability of the brake drum, are arranged at equal distance and protrude upwards. Due to the fact that the thickness of the brake surface is increased and the brake surface is additionally provided with the 36 reinforcing ribs, the stability of the brake drum is greatly improved, meanwhile, the situation of fracture does not occur easily, the brake drum is manufactured to be attractive, the stress area of the brake surface is increased, the durability of the brake drum is greatly improved, and the drum-type brake drum has the advantages that the structure is simple, usage is convenient, and due to the fact that the stress area is increased, the brake drum is better in durability and not prone to being fractured.
Description
Technical field
The utility model belongs to Vehicular brake device technical field, relates to a kind of semitrailer back axle drum brake drum.
Background technique
In semitrailer travels, must on vehicle, install braking device vehicle deceleration is even stopped, so that driver can apply control to vehicle according to situations such as road and traffic, brake, thereby make vehicle deceleration or the parking of travelling, to guarantee traffic safety.Brake drum surface after long-term use is uneven, and there are defects such as sand holes, loose, shrinkage cavity, cause brake drum can not form good dynamic balancing when rotated, when vehicle heavy duty or run at high speed, especially when descending, braking device is frequent to be used and stressed excessive, and the phenomenon that ruptures suddenly can occur, and makes brake failure and causes the accident.
Model utility content
In order to overcome the above-mentioned shortcoming of prior art
,the utility model provides a kind of and has simple and reasonable, easy to usely, thereby can increase lifting surface area, makes brake drum more durable and be difficult for the semitrailer back axle drum brake drum of Fracture Features.
The utility model solves the technological scheme that its technical problem adopts: a kind of semitrailer back axle drum brake drum, comprise a flanged surface for coordinating with wheel hub, on flanged surface, be evenly equipped with several equidistant bolts hole, flanged surface is connected with the zigzag brake lining that carried out thickening processing, is provided with for increasing lifting surface area and also can improves the stiffening rib raising up equidistantly to arrange several of brake drum serviceability on brake lining.
Described flanged surface diameter is 446mm, on flanged surface, be evenly equipped with 10 equidistant bolts hole, length is that the flanged surface of 5mm is connected with the zigzag brake lining that carried out thickening processing, is provided with for increasing lifting surface area and also can improves 36 stiffening ribs that raise up equidistantly to arrange of brake drum serviceability on brake lining.
Described diameter of bolt hole is 40mm.
The length of described brake lining is 249mm.
Described brake lining has wide that leptoprosopy that nose thickness is 35mm and rear end thickness are 60mm.
The rear end of wide, be provided with one for the circular groove of clamping dust-proof cover.
The radius of described groove is 3mm.
The length of described stiffening rib is 120mm, and radius is 2.5mm.
The beneficial effects of the utility model are: by increasing brake lining thickness, and on brake lining, set up stiffening rib, increased substantially the stability of brake drum, be not prone to the situation of fracture simultaneously, and make attractive in appearancely, increased the lifting surface area of brake lining simultaneously, thereby greatly improved the serviceability of brake drum, have simple and reasonable, easy to usely, thereby increase lifting surface area, make the more durable and feature of easy-rupturing not of brake drum.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1-flanged surface, 2-bolt hole, 3-brake lining, 4-groove, 5-dust-proof cover, 6-stiffening rib 7-flanged surface and brake lining joint.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Referring to Fig. 1, a kind of semitrailer back axle drum brake drum, comprise that a diameter is the flanged surface 1 of 446mm for coordinating with wheel hub, on flanged surface 1, be evenly equipped with the bolt hole 2 that 10 equidistant diameters are 40mm, length is that the flanged surface of 5mm is connected with the zigzag brake lining 3 that carried out thickening processing with brake lining joint 7, the length of brake lining 3 is 249mm, brake lining 3 has wide that leptoprosopy that nose thickness is 35mm and rear end thickness are 60mm, the rear end of wide, be provided with the circular groove 4 that a radius for clamping dust-proof cover 5 is 3mm, on brake lining 3, be provided with 36 stiffening ribs that raise up 6 equidistantly to arrange that improve brake drum serviceability for increasing lifting surface area, the length of stiffening rib 6 is 120mm, radius is 2.5mm.
The utility model is by increasing brake lining 3 thickness, and on brake lining 3, set up 36 stiffening ribs 6, greatly improved the stability of brake drum, be not prone to the situation of fracture simultaneously, and make attractive in appearancely, increased the lifting surface area of brake lining 3 simultaneously, thereby greatly improved the serviceability of brake drum, have simple in structure, easy to usely, thereby increase lifting surface area, make the more durable and feature of easy-rupturing not of brake drum.
