Abstract

The invention belongs to the technical field of automobile parts, and relates to a novel light truck hub unit. The novel light truck hub unit mainly comprises a hub, a first bearing and a second bearing. The first bearing and the second bearing are located at the two ends of the hub correspondingly. The first bearing and the second bearing each comprise a holder and a plurality of rolling bodies, and the hub is further connected with a plurality of hub bolts. A combined seal, an O-shaped ring, a single seal, a single seal and a combined seal are arranged in the hub, wherein the combined seals and the single seals are both located between the inner rings and the outer rings of the first bearing and the second bearing, and the O-shaped ring is located between the inner ring large end face of the second bearing and a shaft. It is guaranteed that pre-tightening of the hub unit is proper through matching of the first bearing and the second bearing with the hub, and backlash self-adjustment between the bearings is achieved; and through usage of the double combined seals, the double single seals and the O-shaped ring, the cleanliness in the hub is improved, the cleanliness of the bearing operating environment is guaranteed, and therefore the service life of the bearings is prolonged.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a novel light truck wheel hub unit. Background technique [0002] In recent years, my country's automobile industry has been in a period of rapid development, and the production and sales volume has continued to increase. Considering long-term development, various manufacturers and users have put forward higher requirements for the quality of complete vehicles. A wheel hub must first be installed on the axle of a traditional vehicle, and a plurality of fixing screws or nuts are arranged on the end surface of the wheel hub, and the spokes of the wheel hub are fixed on the wheel hub through nuts or screws. The hub unit with the above structure needs to be fixed by multiple screws or nuts in order to realize the connection between the hub and the spoke rim, which is particularly cumbersome in today’s era of work efficiency, the structure is too complicated, the cost i...
