It is certainly existing in the prior art bad due to radiating, cause brake drum to overheat, braking ability decline or even brake drum cracking etc. are asked
Topic；The problems such as since hub inner lumen is excessive, causing grease up excessive, generating lubricating grease waste of material.
The utility model is achieved through the following technical solutions:
A kind of novel hub assembly, including brake drum 1, brake drum inner cavity inner hole 2, wheel hub 3, hub inner lumen 4, brake are total
At 5, lubricating grease 6, wheel hub outer bearing 7, tire bolt 8, hub inner bearing 9 and hub oil seal 10；Wherein, outside the wheel hub
Bearing 7, hub inner bearing 9 outer diameter be respectively pressed into the bearing hole of wheel hub 3, end face fitting；The diameter of axle of hub oil seal 10 is pressed into wheel
The oil sealing hole of hub 3, end face fitting；The distribution flange hole of wheel hub 3 is aligned with the distribution flange hole of brake drum 1, is connected with tire bolt 8
It is connected together；The hub inner lumen 4 of wheel hub 3 injects lubricating grease 6, the lubrication for hub bearing；Using distribution outside hub inner lumen 4
Stud structure, for increasing the heat dissipation of intensity and brake drum inner cavity inner hole 2；The brake drum inner hole 2 and brake assembly of brake drum 1
5 friction plate cooperation, realizes braking function.
Further, the hub inner lumen 4 is taper pass.
Further, the stud structure is starting with hub inner lumen 4 radially centered on the axis of wheel hub 3,
It is to terminate with 3 outer profile tapered surface of wheel hub, it is radial uniformly distributed；It is located axially at leaning on for wheel hub outer bearing 7 and hub inner bearing 9
Between 4 both ends of the surface of nearly hub inner lumen.
A kind of working principle of novel hub assembly of the invention is as follows:
When brake, the friction plate sliding friction of the brake drum inner cavity inner hole 2 and brake assembly 5 of brake drum 1 is produced
Raw heat is enclosed in brake drum inner cavity inner hole 2, and wheel hub 1 rotates, and the stud structure of distribution drives the sky in brake drum inner cavity 2
Gas quickly flows, and heat is discharged with air.
Compared with prior art, as follows the advantages of the utility model:
Hub assembly of the invention drives rapid air movement using distribution stud structure, stud when rotating, increase intensity
While improve the heat dissipation performance of brake drum inner cavity；The space of relatively traditional no stud structure, hub inner lumen reduces, and guarantees
Under the premise of the lubricating function of hub bearing, the lubricating grease that need to be injected is reduced, and is reduced costs.
