Air Suspension Device for Sightseeing Vehicle

Technical Field

The utility model relates to a sightseeing vehicle, and particularly to an air suspension device for a sightseeing vehicle.

Background Technology

With the development of the national economy, the tourism industry in China has also been rapidly growing. Scenic area facilities require comprehensive upgrades to meet consumer demands. As essential transportation equipment in large scenic areas, sightseeing vehicles are widely used. Existing suspension systems for sightseeing vehicles generally adopt leaf spring buffering structures, which provide poor cushioning performance. Especially in natural scenic areas where road conditions are relatively complicated, passenger riding comfort is poor. Therefore, improving the comfort of sightseeing vehicles is highly necessary.

Summary of the Utility Model

In order to solve the above problems, the utility model provides an air suspension device for a sightseeing vehicle, which offers high buffering performance.

To achieve the above purpose, the utility model adopts the following technical solution:

An air suspension device for a sightseeing vehicle comprises an air bag assembly, a shock absorber assembly, a lower swing arm assembly, an upper swing arm assembly, a subframe welded assembly, a fixing bracket, a steering mechanism, and a wheel-side steering assembly.

The air bag assembly is arranged at the lower part of the vehicle frame, and the lower end of the air bag assembly is connected with the upper swing arm assembly. One end of the shock absorber assembly is connected with the vehicle frame, while the other end is connected with the lower swing arm assembly. The subframe welded assembly is connected with the vehicle frame through the fixing bracket. One end of the upper swing arm assembly is connected with the subframe welded assembly, and the other end is connected with the wheel-side steering assembly through a ball pin. One end of the lower swing arm assembly is connected with the subframe welded assembly. The steering mechanism is connected with the wheel-side steering assembly.

Further Description

The steering mechanism comprises a steering gear, a steering drag link, steering tie rods, a steering arm assembly, and a T-shaped steering arm. The steering gear is connected with the steering arm assembly through the steering drag link. Two steering tie rods are connected with the steering arm assembly. One end of the T-shaped steering arm is connected with the steering tie rod, and the other end is connected with the wheel-side steering assembly.

A single steering drag link controls the two steering tie rods to complete steering actions, featuring a simple structure, good stability, and lower manufacturing cost.

Further, the air bag assembly comprises an upper air bag bracket, an air bag, and an air bag backing plate. The air bag is connected with the vehicle frame through the upper air bag bracket, and is connected with the upper swing arm assembly through the air bag backing plate.

Further, the shock absorber assembly comprises a shock absorber and an upper shock absorber bracket. The upper end of the shock absorber is connected with the vehicle frame through the upper shock absorber bracket. The shock absorber is arranged at a certain angle relative to the vertical plane and passes through the upper swing arm assembly to connect with the lower swing arm assembly.

Further, the lower portion of the upper swing arm assembly is provided with a hanger bracket assembly. One side of the hanger bracket assembly is provided with a transverse stabilizer bar, which is connected with the subframe welded assembly through a fixing bracket.

Further, the upper swing arm assembly and the lower swing arm assembly have the same structure.

Further, the upper swing arm assembly is designed as a stamped and welded component with a hollow middle section, featuring a simple structure, reduced weight, and convenient assembly.

Beneficial Effects

Compared with the prior art, the utility model has the following beneficial effects:

All components of the air suspension device are fixed onto the vehicle frame through bolts, making installation and maintenance convenient.

The air bag assembly, in cooperation with a height valve, can automatically adjust the height of the vehicle frame, ensuring that the vehicle body always remains at a preset height.

This effectively solves the dual problems of excessive vehicle height making passenger boarding inconvenient, and insufficient ground clearance caused by an overly low body height.

The transverse stabilizer bar effectively prevents lateral rollover of the sightseeing vehicle and improves ride smoothness.

The inclined shock absorber can buffer forces in both vertical and horizontal directions acting on the vehicle frame.

The entire structure is more stable, providing better passenger experience and higher comfort.

Specific Embodiment

As shown in Figures 1–4, the air suspension device for a sightseeing vehicle includes an air bag assembly 1, shock absorber assembly 2, lower swing arm assembly 3, upper swing arm assembly 4, subframe welded assembly 5, fixing bracket 6, steering mechanism, and wheel-side steering assembly 7.

The air bag assembly 1 is arranged below the vehicle frame 8, and the lower end of the air bag assembly 1 is connected with the upper swing arm assembly 4. One end of the shock absorber assembly 2 is connected with the vehicle frame 8, and the other end is connected with the lower swing arm assembly 3.

The subframe welded assembly 5 is connected with the vehicle frame 8 through the fixing bracket 6. One end of the upper swing arm assembly 4 is connected with the subframe welded assembly 5, and the other end is connected with the wheel-side steering assembly 7 through the ball pin 9. One end of the lower swing arm assembly 3 is connected with the subframe welded assembly 5, while the other end is connected with the wheel-side steering assembly 7 through the ball pin 9.

The steering mechanism includes the steering gear 17, steering drag link 10, steering tie rods 11, steering arm assembly 12, and T-shaped steering arm 13. The steering gear 17 is connected with the steering arm assembly 12 through the steering drag link 10. Two steering tie rods 11 are connected with the steering arm assembly 12. One end of the T-shaped steering arm 13 is connected with the steering tie rod 11, and the other end is connected with the wheel-side steering assembly 7.

The air bag assembly 1 includes an upper air bag bracket 101, air bag 102, and air bag backing plate 103. The air bag 102 is connected with the vehicle frame 8 through the upper air bag bracket 101, and connected with the upper swing arm assembly 4 through the air bag backing plate 103.

The shock absorber assembly 2 includes the shock absorber 21 and upper shock absorber bracket 22. The upper end of the shock absorber 21 is connected with the vehicle frame 8 through the upper shock absorber bracket 22. The shock absorber 21 is inclined at a certain angle relative to the vertical plane and passes through the upper swing arm assembly 4 to connect with the lower swing arm assembly 3.

Working Principle

During operation of the sightseeing vehicle, the height valve controls inflation and deflation of the air bag 102 to adjust vehicle body height. The shock absorber 21 is inclined relative to the vertical plane, thereby buffering forces acting on the vehicle frame 8 in both vertical and horizontal directions.

All components of the air suspension device are fixed onto the vehicle frame 8 through bolts, making disassembly, installation, and subsequent maintenance more convenient.
