Problems solved by technology

The amount of lubricating grease installed in different axles is different, but generally speaking, the amount of oil stored in the oil storage cavity is still too much, and most of the lubricating grease is in the hub cavity. When rotating, the lubricating grease in the hub cavity cannot enter the bearing for lubrication, resulting in waste of lubricating grease

Embodiment Construction

[0018] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, on the existing trailer axle, most of the lubricating grease 8 used for the lubrication of the inner and outer bearings of the axle is stored in the hub cavity between the hub and the axle head. Even when the axle rotates at a high speed, the grease in the hub cavity cannot enter the bearing. Internal lubrication.

[0020] Such as figure 2 , 3 , 4, the present invention discloses a wheel hub oil storage system. The trailer axle is a follower axle, which bears the weight of the vehicle and the cargo load, and is used to support the rotation of the tire. It mainly includes the axle body, wheel hub 1, brake drum, brake shoe assembly, and camshaft assembly. The axle body is divided into shaft The tube and the shaft head 2 at both ends are two parts. The hub 1 and the brake drum assembly are assembled o...

Abstract

The invention discloses a hub oil storage system which comprises an axle head and a hub. An inner bearing and an outer bearing are mounted between the axle head and the hub. Areas for mounting the inner bearing and the outer bearing are bearing chambers, and a hub chamber is between the two bearing chambers. The outer side of the inner bearing is provided with a hub oil seal, and the outer side of the outer bearing is provided with an oil retaining ring. Lubricating grease is further stored in the hub for lubricating the inner bearing and the outer bearing. A middle sleeve is arranged in the hub and is connected with outer rings of the inner bearing and the outer bearing. The lubricating grease is stored in the bearing chambers. The middle sleeve is sleeved on a hub inner chamber between the inner bearing and the outer bearing, and the oil retaining ring is mounted on the outer side of the outer bearing, so that the lubricating grease is gathered on the inner bearing and the outer bearing, usage amount of the lubricating grease is reduced, utilization rate of the lubricating grease is increased, pollution is reduced, low-carbon environment-friendly effect is achieved, lubricating effect is evident, friction resistance is reduced, wear is relieved, and the bearings are more durable.

Description

technical field [0001] The invention relates to the technical field of oil storage systems, and more specifically relates to a wheel hub oil storage system on a trailer axle. Background technique [0002] With the deepening of the market economy, the road transportation industry has made great progress, and the scope of use of ordinary trailers is becoming wider and wider. The trailer axle is a follower axle, which bears the weight of the vehicle and the cargo load, and is used to support the rotation of the tire. It mainly includes the axle body, wheel hub, brake drum, brake shoe assembly, and camshaft assembly. The axle body is divided into axle tubes The hub and the brake drum assembly are assembled on the shaft heads at both ends of the shaft body to perform wheel rotation and braking. The brake shoe assembly is installed in the brake drum, and the brake pads are made of It is made of asbestos-free friction and environmental protection materials. There are inner and out...
