Technical Field

The invention belongs to the technical field of caravan suspension structures, and particularly relates to a wheel hydraulic lifting mechanism.

Background

The chassis of the motor home should have good stability, and the safety and the comfort of the motor home are guaranteed. The supporting leg structure that a plurality of can stretch out and draw back is installed to prior art adoption on the substructure of car as a house, when needs fixed car as a house, makes the supporting leg stretch out, supports and leans on subaerial, has improved the stability of car as a house to a certain extent. However, since the support legs are generally slender structures, the caravan still has a risk of toppling under severe conditions such as strong wind. In order to further improve the stability of the motor home, lowering the center of gravity of the motor home is a key to improve the stability of the motor home. However, the prior art can only reduce the height of the chassis of the caravan in a limited way, and the chassis cannot be completely realized on the ground.

Therefore, the prior art is yet to be further studied.

Disclosure of Invention

The invention aims to provide a wheel hydraulic lifting mechanism, aiming at solving the problem that a chassis cannot be completely fixed on the ground.

In order to solve the problems, the technical scheme adopted by the invention is as follows: the utility model provides a wheel hydraulic lifting mechanism, includes chassis and multiunit wheel hub group, all set up wheel swing arm mechanism between wheel hub group and the chassis, wheel swing arm mechanism includes swing arm support and cantilever, driving cylinder between one of them swing arm support and the chassis, driving cylinder's base swing joint is on the chassis, driving cylinder's piston links to each other with the swing arm support, the swing arm support is fixed on the chassis with the stiff end of cantilever, the free end of cantilever links to each other with wheel hub group, establish damper between cantilever one end and the swing arm support, set up stop gear between the cantilever other end and the swing arm support.

A synchronous connecting rod is arranged between the wheel swing arm mechanisms, and the free end of the swing arm support is connected with the synchronous connecting rod.

The chassis comprises chassis girders and a wheel shaft arranged between the chassis girders, and the fixed ends of the swing arm support and the cantilever are fixed at two ends of the wheel shaft.

The fixed end of the swing arm support corresponds to the wheel shaft and is provided with a mounting hole, and the limiting mechanism comprises a rubber spring ball and a spring ball mounting vertical plate.

The rubber spring ball is embedded with a metal bolt piece, and is fixed on the spring ball mounting vertical plate through the metal bolt piece.

The damping mechanism comprises a rubber damping block and a damping block mounting seat, the rubber damping block comprises a plurality of groups of trapezoidal rubber blocks, and the rubber damping block is integrally formed.

The damping block mounting seat is fixed on the cantilever, one end of the rubber damping block is fixed on the swing arm support, and the other end of the rubber damping block is fixed on the damping block mounting seat.

Every two sets of the wheel hub sets comprise a front wheel hub set and a rear wheel hub set, and the wheel swing arm mechanisms and the front wheel hub set and the rear wheel hub set respectively comprise a front swing arm mechanism and a rear swing arm mechanism.

The driving oil cylinder is a hydraulic oil cylinder, and the tail end of the hydraulic oil cylinder is fixed on a crossbeam of the chassis.

The front wheel hub group comprises two pairs of front wheel hubs which are arranged in a group, the rear wheel hub group comprises two pairs of rear wheel hubs which are arranged in a group, and tires are arranged on the front wheel hubs and the rear wheel hubs.

The invention has the beneficial effects that:

1. the lifting device comprises a chassis and a hub group, wherein a wheel swing arm mechanism is arranged between the hub group and the chassis, a synchronous connecting rod is arranged between the wheel swing arm mechanisms, the wheel swing arm mechanism comprises a swing arm support and a cantilever, a driving oil cylinder is arranged between the swing arm support and the chassis, a tire is arranged on the hub group, and the driving oil cylinder drives the swing arm support and the cantilever to lift the chassis.

2. The invention sets synchronous connecting rod between wheel swing arms, drives tyre to move up and down through the synchronous connecting rod and wheel swing arm mechanism, is suitable for single-group wheel hub group and chassis of multi-group wheel hub, drives rear wheel swing arm mechanism to move and synchronizes front wheel swing arm mechanism, falls tyre, forces chassis to leave ground, reaches driving state, retracts oil cylinder, drives rear wheel swing arm structure to rise and synchronizes front wheel swing arm mechanism, and steadily falls chassis to ground.

3. The invention aims to realize that the box body of the caravan can normally run and can stably fall on the ground integrally after the caravan reaches a destination, thereby reducing the height of a carriage from the ground and greatly improving the stability and the safety of the caravan and the convenience of goods transportation.

4. The rubber spring ball is arranged on the cantilever, and plays a role in limiting when the tire returns; that is to say, a limiting effect of the reverse running of the tire under the action of the rubber shock absorption block is avoided.
