Air Suspension Device for a Sightseeing Vehicle

Technical Field

The present invention relates to a sightseeing vehicle, and particularly relates to an air suspension device for a sightseeing vehicle.

Background Technology

With the development of the national economy, China's tourism industry has continued to improve, and scenic area facilities also require comprehensive upgrading to meet consumer demands. As essential transportation equipment in large scenic areas, sightseeing vehicles are widely used. In the prior art, the suspension systems of sightseeing vehicles generally adopt leaf spring buffer structures, which have poor cushioning performance. Especially in natural scenic areas where road conditions are relatively complex, passenger riding comfort is even worse. Therefore, improving the comfort of sightseeing vehicles is highly necessary.

Summary of the Invention

In order to solve the above problems, the present invention provides an air suspension device for a sightseeing vehicle, thereby providing a suspension device with high buffering performance.

To achieve the above objective, the present invention 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 welding assembly, fixing brackets, a steering mechanism, and a wheel-side steering assembly.

The air bag assembly is arranged at the lower portion 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 welding assembly is connected with the vehicle frame through the fixing brackets. One end of the upper swing arm assembly is connected with the subframe, 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 welding assembly, and the steering mechanism is connected with the wheel-side steering assembly.

Further Technical Features

Further, the steering mechanism comprises a steering gear, a steering drag link, steering tie rods, a steering rocker arm assembly, and a steering T-arm. The steering gear is connected with the steering rocker arm assembly through the steering drag link. Two steering tie rods are connected with the steering rocker arm assembly. One end of the steering T-arm is connected with the steering tie rods, and the other end is connected with the wheel-side steering assembly. By using one steering drag link to control two steering tie rods to complete steering actions, the structure is simple, stable, and lower in 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 forms a certain angle with 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, and one side of the hanger bracket assembly is provided with a transverse stabilizer bar. The transverse stabilizer bar is connected with the subframe welding assembly through fixing brackets.

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

Further, the upper swing arm assembly is configured 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 present invention has the following beneficial effects:

Each component of the air suspension device is fixed onto the vehicle frame by bolts, making installation and maintenance convenient.

By coordinating the air bag assembly with a height valve, the height of the vehicle frame can be automatically adjusted, allowing the vehicle body to remain at a preset height at all times.

This effectively solves the dual problems of excessive vehicle height causing inconvenience for passengers to get on and off, and insufficient ground clearance caused by a low vehicle body.

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

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

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

Specific Embodiments

As shown in Figures 1–4, an air suspension device for a sightseeing vehicle comprises an air bag assembly 1, a shock absorber assembly 2, a lower swing arm assembly 3, an upper swing arm assembly 4, a subframe welding assembly 5, fixing brackets 6, a steering mechanism, and a 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 welding assembly 5 is connected with the vehicle frame 8 through the fixing brackets 6. One end of the upper swing arm assembly 4 is connected with the subframe welding assembly 5, and the other end is connected with the wheel-side steering assembly 7 through a ball pin 9. One end of the lower swing arm assembly 3 is connected with the subframe welding assembly 5, and the other end is connected with the wheel-side steering assembly 7 through a ball pin 9. The steering mechanism is connected with the wheel-side steering assembly 7.

Further, the steering mechanism comprises a steering gear 17, a steering drag link 10, steering tie rods 11, a steering rocker arm assembly 12, and a steering T-arm 13.

Working Principle

During operation of the sightseeing vehicle, a height valve controls the inflation and deflation of the air bag 102 to adjust the vehicle body height. The shock absorber 21 is arranged at an angle relative to the vertical plane, thereby providing cushioning effects for both vertical and horizontal forces acting on the vehicle frame 8. All components of the air suspension device are fixed onto the vehicle frame 8 through bolts, making disassembly, installation, and subsequent maintenance more convenient.
