When the vehicle runs for a certain time, the friction plate can be directly replaced after being worn, and the replacement cost after sale is low.
4. The weight is light:
the hub assembly of the invention cancels a brake disc and adopts a friction plate and a heat insulation plate which are connected with the hub body to replace the brake disc. The wheel side weight of the non-brake disc structure is greatly reduced, and the light weight of the wheel hub is realized.
In addition, one or more through holes are formed in the front shaft, so that the weight of the front shaft can be reduced, and the effect of light weight of the whole vehicle is achieved.
5. The service life is long:
according to the invention, the heat insulation plate is arranged between the friction plate and the braking boss of the hub assembly, and the heat insulation plate is made of high-strength nano materials, so that heat generated by the friction plate is prevented from being transferred to the hub, and the service life of a hub bearing and an oil seal of the hub assembly is ensured.
In addition, the hub bearing is an integrated unit bearing, and the bearing clearance is adjusted in the bearing production link, so that the assembly efficiency of the axle assembly can be improved, and the influence on the service life of the bearing due to improper clearance adjustment is avoided. Therefore, the service life of the invention is long.
6. The bearing capacity of the front axle can be ensured:
although the front axle is provided with one or more through holes, the front axle adopts a high-strength 42CrMo material, so that the strength of the front axle can be improved, the bearing capacity of the front axle is ensured, and the front axle is easy to popularize and use.
The technical features of the front axle assembly of the present invention will be further described with reference to the accompanying drawings and embodiments.
