Rear Suspension Device for a Sightseeing Vehicle

Technical Field

The present utility model relates to a sightseeing vehicle, and particularly relates to a rear 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.

Utility Model Content

In order to solve the above problems, the present utility model provides a rear suspension device for a sightseeing vehicle, featuring a simple structure and excellent cushioning performance for the rear frame air suspension system.

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

A rear suspension device for a sightseeing vehicle comprises a leaf spring, a fixing bracket, a pressing plate, a shock absorber assembly, an air bag assembly, U-bolts, and hangers. The leaf spring is arranged below the vehicle frame through the fixing bracket. The air bag assembly is arranged between the leaf spring and the vehicle frame. The upper end of the shock absorber assembly is connected with the vehicle frame, while the lower end of the shock absorber assembly is connected with the hangers. The hangers are arranged on both sides of the drive axle. The leaf spring is connected with the drive axle through the pressing plate and U-bolts.

Further Technical Features

Further, a limiting block is arranged on the vehicle frame directly above the drive axle to limit the minimum height of the vehicle body, preventing the frame from pressing against the tires when the air bag loses air pressure, thereby ensuring that the frame does not rub against the tires and that the vehicle can continue operating normally.

Further, a transverse thrust rod is arranged on the drive axle. One end of the transverse thrust rod is connected with the drive axle, and the other end is connected with the vehicle frame. This prevents excessive lateral body roll during cornering, thereby preventing vehicle rollover and improving ride smoothness.

Further, the shock absorber assembly comprises a shock absorber and an upper fixing bracket, and the shock absorber is connected with the vehicle frame through the upper fixing bracket.

Further, the air bag assembly comprises an air bag and an upper fixing bracket, and the air bag is connected with the vehicle frame through the upper fixing bracket.

Beneficial Effects

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

The vehicle body height can be adjusted through the air bag.

The shock absorber improves vehicle stability.

The air bag, shock absorber, and vehicle frame are connected together through the leaf spring, thereby improving overall vehicle stability and cushioning performance.

Passenger riding comfort is significantly improved.

Specific Embodiments

As shown in Figures 1 and 2, a rear suspension device for a sightseeing vehicle comprises a leaf spring 1, a fixing bracket 2, a pressing plate 3, a shock absorber assembly 4, an air bag assembly 5, U-bolts 6, and hangers 7.

The leaf spring 1 is arranged below the vehicle frame 8 through the fixing bracket 2. The air bag assembly 5 is arranged between the leaf spring 1 and the vehicle frame 8. The upper end of the shock absorber assembly 4 is connected with the vehicle frame 8, while the lower end of the shock absorber assembly 4 is connected with the hangers 7. The hangers 7 are arranged on both sides of the drive axle 9. The leaf spring 1 is connected with the drive axle 9 through the pressing plate 3 and U-bolts 6.

Further, a limiting block 10 is arranged on the vehicle frame directly above the drive axle 9 to limit the minimum height of the vehicle body, preventing the frame from pressing against the tires when the air bag loses air pressure, thereby ensuring that the frame does not rub against the tires and that the vehicle can continue operating normally.

Further, a transverse thrust rod 11 is arranged on the drive axle 9. One end of the transverse thrust rod 11 is connected with the drive axle 9, and the other end is connected with the vehicle frame 8. This prevents excessive lateral body roll during cornering, with the purpose of preventing vehicle rollover and improving ride smoothness.

Further, the shock absorber assembly 4 comprises a shock absorber and an upper fixing bracket, and the shock absorber is connected with the vehicle frame 8 through the upper fixing bracket.

Further, the air bag assembly 5 comprises an air bag and an upper fixing bracket, and the air bag is connected with the vehicle frame 8 through the upper fixing bracket.

Working Principle

The working principle and process of the present utility model are as follows:

The height of the vehicle frame is adjusted through inflation and deflation of the air bag, allowing adaptation to different road conditions. The shock absorber provides buffering and vibration reduction, while the leaf spring also provides a certain cushioning effect. The structure is simple, and all components are connected to the vehicle frame through bolts, making installation and maintenance convenient.

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

The air bag adjusts the vehicle body height, the shock absorber improves vehicle stability, and the air bag, shock absorber, and vehicle frame are connected together through the leaf spring, thereby improving overall vehicle stability and cushioning performance and enhancing passenger comfort.

Any similar technical solution designed by those skilled in the art based on the technical inspiration of the present utility model, and achieving the above technical effects, shall fall within the protection scope of the present utility model.
