Description

Air suspension steering structure

Technical Field

The utility model relates to the technical field of automobile suspension, in particular to an air suspension steering structure.

Background

At present, leaf springs are mostly adopted for hanging trailers of trucks in China. With the rapid development of national economy and the improvement of road traffic conditions, people put higher demands on the riding comfort of trucks and the integrity of protecting goods, and in order to solve the problems, a hybrid suspension device adopting plate springs and air suspension is presented. The leaf springs of the two suspension devices are fixedly arranged on the axle, namely, the two suspension devices are both fixed suspension devices.

The prior art has the following problems:

in the using process of the general air suspension, when the air is sealed, the front wheel steering function is not provided, so that the steering is not sensitive enough, and the using effect of the air suspension is reduced.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides an air suspension steering structure, which solves the problems that the steering is insensitive and the using effect of the air suspension is reduced because the front wheel steering function is not provided when the air suspension seals the air in the prior art.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides an air suspension turns to structure, includes sealed lid, sealed lower extreme of lid is provided with the vibration isolation piece, the outside cover of vibration isolation piece has the bearing inner race seat, the outside of bearing inner race seat is provided with the bearing, the outside of bearing is provided with the fixing base, the lower extreme of fixing base is provided with the casing.

As a preferable technical scheme of the utility model, the outer diameter size of the sealing cover is matched with the inner diameter size of the bearing inner ring seat, and the sealing cover is plugged into the bearing inner ring seat in the assembly process.

As a preferable technical scheme of the utility model, the vibration isolation block is in a sleeve shape, and the outer diameter size of the vibration isolation block is matched with the inner diameter size of the bearing inner ring seat.

As a preferable technical scheme of the utility model, the inner diameter size of the bearing is matched with the outer diameter size of the bearing inner ring seat, and the bearing is sleeved outside the bearing inner ring seat.

As a preferable technical scheme of the utility model, a baffle is arranged in the fixing seat, the baffle is in a circular ring shape, and the inner diameter size of the baffle is matched with the outer diameter size of the bearing.

Compared with the prior art, the utility model provides an air suspension steering structure, which comprises the following components

The beneficial effects are that:

this air suspension turns to structure through setting up sealed lid, vibration isolation piece, bearing inner race seat, fixing base and last casing, can realize that the air suspension seals up the front wheel turns to when air, has not only mentioned the sensitivity that the air suspension turns to the structure and turns to, but also can avoid the air suspension to turn to the condition that the structure operation in-process damaged appears, improves structure safety in utilization.
