Embodiment 1

[0026] Such as figure 1 As shown, a new type of heavy truck hub unit mainly includes a hub 1, a first bearing 2 and a second bearing 3, the first bearing 2 and the second bearing 3 are respectively located at both ends of the hub 1, the first bearing 2 and the second bearing 3 contain a cage, inner and outer rings and a number of rolling elements.

[0027] The inner right end of the hub 1 is sequentially provided with a combined sealing ring 6, an O-ring 4, a single sealing ring 5, a single sealing ring 5, an O-ring 4, and a combined sealing ring 6 from right to left, and the combined sealing ring 6 is located at the first Between the large rib of the inner ring of the bearing 2 and the second bearing 3 and the inner cavity of the hub 1, the single seal ring 5 is located between the inner and outer rings of the first bearing 2 and the second bearing 3, and the O-ring 4 is located in the first bearing 2 And between the inner ring of the second bearing 3 and the shaft 8 . Wher...

Embodiment 2

[0031] A new type of wheel hub unit for heavy trucks, mainly including a hub 1, a first bearing 2 and a second bearing 3, the first bearing 2 and the second bearing 3 are respectively located at both ends of the hub 1, the first bearing 2 and the second bearing 3 are both Contains a cage, inner and outer rings and several rolling elements.

[0032] The inner right end of the hub 1 is sequentially provided with a combined sealing ring 6, an O-ring 4, a single sealing ring 5, a single sealing ring 5, an O-ring 4, and a combined sealing ring 6 from right to left, and the combined sealing ring 6 is located at the first Between the large rib of the inner ring of the bearing 2 and the second bearing 3 and the inner cavity of the hub 1, the single seal ring 5 is located between the inner and outer rings of the first bearing 2 and the second bearing 3, and the O-ring 4 is located in the first bearing 2 And between the inner ring of the second bearing 3 and the shaft 8 . Wherein, ther...

Embodiment 3

[0036] The difference from the first two embodiments of embodiment 1 and embodiment 2 is that the type of rolling elements in the present invention is a cylindrical roller.

[0037] In the new heavy-duty truck hub unit disclosed by the present invention, the seal between the first bearing 2 and the second bearing 3 and the hub 1 is assembled and sealed by a combined seal 6 with rubber at the top, and the outer side of the labyrinth combined seal 6 is connected to the hub. The inner side of 1 is in close contact, and the inner side of the combined seal 6 is in close contact with the large ribs of the inner rings of the first bearing 2 and the second bearing 3, so that a closed seal is formed between the first bearing 2, the second bearing 3, the combined seal 6 and the hub 1 The grease circulation system can not only prevent oil leakage, but also prevent external dust from entering, thus prolonging the service life of the hub unit.

[0038] In the new heavy-duty truck hub unit ...

Abstract

The invention belongs to the technical field of car spare parts, and relates to a novel heavy truck car hub unit. The 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 are each comprises a retainer, an inner collar, an outer collar and a plurality of rolling bodies. A combined sealing ring, an O-shaped ring, a single sealing ring, a sing sealing ring, an O-shaped ring and a combined sealing ring are sequentially arranged at the right end in the hub from right to left. The combined sealing rings are arranged between a large flange of an inner ring of the first bearing and the hub as well as between a large flange of an inner ring of the second bearing and the hub correspondingly. The single sealing rings are located between inner and outer rings of the first bearing as well as between the inner and outer rings of the second bearing. The O-shaped rings are located between the first bearing and a shaft as well as between the second bearing and the shaft. According to the novel heavy truck car hub unit, the bearing base planes and a shaft shoulder are used positioning, an original space ring structure is omitted, and the assembling process can be simplified; and the structure is simple, the unit has the advantages of being convenient to mount and replace, the mounting efficiency can be improved, and the unit has high market popularization value.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a novel heavy truck hub unit. Background technique [0002] With the rapid development of social economy, automobiles are gradually becoming people's main means of transportation, and the demand for wheel hub units is also increasing year by year. Especially in recent years, my country's automobile industry is in a period of rapid development, and production and sales continue to increase. In consideration of 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 r...
