Abstract
The utility model provides a trailer axle assembly, which comprises a hub, a hub end cover, a bearing, a drum brake, a friction lining, a brake shoe, a roller, a camshaft, an axle tube, a bottom plate and a dust guard, the bottom plate is provide with a shoe shaft hole, the upper end of the bottom plate is provided with a temperature sensor, a water jet tube is fixed on the dust guard, the water outlet end of the water jet tube is between the friction lining and the drum brake, and the water inlet end of the water jet tube is connected with an automobile radiator. The trailer axle assembly using the bottom plate, which comes up to the part standard of Dongfeng Motor Corporation, has the advantages of exchangeability, lighter structure and high reliability, and is convenient to replace and maintain; since the trailer axle assembly is added with the temperature sensor, when the braking temperature is overhigh, the trailer axle assembly can automatically jet water to reduce the temperature, and thereby the safety and reliability of the whole axle are enhanced; the bottom plate is a steel casting, and can be directly welded on the burnished axle tube, and thereby the production cost can be reduced.
Description
Technical field
The utility model relates to a kind of auto parts and components, especially a kind of trailer axle assembly.
Background technology
Existing trailer axle parts are non-east wind company standard, so east wind company service station can not keep in repair or change.Simultaneously, the back-plate glancing impact can produce high temperature and easily make braking hub cracking, causes the generation of accident, and reliability, bearing capacity and heat-sinking capability are poor.And back-plate is a foundry goods, and back-plate and axletree are that weight is bigger by bolted, has oil consumption, problem that cost of manufacture is high.
Summary of the invention
The utility model purpose provides a kind of in light weight, and cost is low, can reduce the high temperature that glancing impact produces automatically, prevents to brake the hub cracking, the trailer axle assembly that reliability safety economy is higher.
In order to solve the problems of the technologies described above, the technical solution of the utility model one is as follows: described trailer axle assembly, comprise wheel hub, wheel hub end housing, bearing, braking hub, friction lining, brake shoe brake cheek, roller, camshaft, central siphon, base plate, dust boot, it is characterized in that: described base plate is provided with 1 shoe plate axis hole, the base plate upper end is provided with temperature sensor, be fixed with water jet standpipe on the dust boot, the water side of water jet standpipe is between friction lining and brake wheel, and water inlet end is connected with radiator.
Improvement to technical scheme one: described base plate is a steel casting.
In order to solve the problems of the technologies described above, the technical solution of the utility model two is as follows: the trailer axle assembly, comprise wheel hub, wheel hub end housing, bearing, braking hub, friction lining, brake shoe brake cheek, roller, camshaft, central siphon, base plate, dust boot, it is characterized in that: described base plate is provided with 2 pairs of shoe plate axis holes, the base plate upper end is provided with temperature sensor, be fixed with water jet standpipe on the dust boot, the water side of water jet standpipe is between friction lining and brake wheel, and water inlet end is connected with radiator.
Improvement to technical scheme two: described base plate is a steel casting.
Beneficial effect:
Use the trailer axle assembly of base plate described in the utility model, with the part-subassemble standard unification of east wind company, has interchangeability, structure is lighter and handier, replacing, easy to maintenance, the advantage that reliability is high, add temperature sensor, when brake temperature is too high, can lower the temperature by automatic water jetting, improved the safety and the reliability of whole bridge; Base plate is a steel casting, can be directly and the welding of edging last item pipe, can reduce manufacturing cost.
