Suspension System for Sightseeing Vehicle

Technical Field

The present invention relates to a sightseeing vehicle, and particularly to a suspension system for a sightseeing vehicle.

Background Technology

With the development of the national economy, China’s tourism industry has continued to expand, and the scale of the industry has grown rapidly. Scenic area facilities also require comprehensive upgrades to meet consumer demands. As essential transportation equipment in large scenic areas, sightseeing vehicles are widely used.

Conventional 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 complex, passenger comfort is significantly reduced. Therefore, improving the riding comfort of sightseeing vehicles is highly necessary.

Summary of the Invention

To solve the above problems, the present invention provides a suspension system for a sightseeing vehicle with a compact structure, convenient disassembly, and excellent cushioning performance.

To achieve the above purpose, the present invention adopts the following technical solution:

A suspension system for a sightseeing vehicle includes a front frame air suspension assembly and a rear frame air suspension assembly. Since sightseeing vehicles are generally designed with front-wheel drive, the front frame air suspension assembly differs from the rear frame air suspension assembly by requiring an additional steering structure.

The front frame air suspension assembly includes:

Air spring assembly I

Shock absorber assembly I

Lower swing arm assembly

Upper swing arm assembly

Subframe welded assembly

Mounting bracket

Steering mechanism

Wheel-side steering assembly

The air spring assembly I is arranged at the lower portion of the vehicle frame, and the lower end of the air spring assembly I is connected to the upper swing arm assembly.

One end of the shock absorber assembly I is connected to the frame, while the other end is connected to the lower swing arm assembly.

The subframe welded assembly is connected to the frame through mounting brackets.

One end of the upper swing arm assembly is connected to the subframe welded assembly, and the other end is connected to the wheel-side steering assembly through a ball pin.

One end of the lower swing arm assembly is connected to the subframe welded assembly.

The steering mechanism is connected to the wheel-side steering assembly.

The rear frame air suspension assembly includes:

Leaf spring

Leaf spring mounting bracket

Pressure plate

Shock absorber assembly II

Air spring assembly II

U-bolt

Hanger bracket

The leaf spring is mounted below the frame through the leaf spring mounting bracket.

The air spring assembly II is arranged between the leaf spring and the frame.

The upper end of shock absorber assembly II is connected to the frame, while the lower end is connected to the hanger bracket.

The hanger brackets are arranged on both sides of the drive axle.

The leaf spring is connected to the drive axle through the pressure plate and U-bolts.

Further Technical Features

Steering Mechanism

The steering mechanism includes:

Steering gear

Steering drag link

Steering tie rods

Steering arm assembly

T-shaped steering arm

The steering gear is connected to the steering arm assembly through the steering drag link.

Two steering tie rods are connected to the steering arm assembly.

One end of the T-shaped steering arm is connected to the steering tie rod, and the other end is connected to the wheel-side steering assembly.

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

Air Spring Assembly I

Air spring assembly I includes:

Upper air spring bracket

Air spring I

Air spring backing plate

The air spring I is connected to the frame through the upper air spring bracket and connected to the upper swing arm assembly through the air spring backing plate.

Shock Absorber Assembly I

Shock absorber assembly I includes:

Shock absorber I

Upper shock absorber bracket

The upper end of shock absorber I is connected to the 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.

Stabilizer Structure

A hanger bracket assembly is arranged at the lower portion of the upper swing arm assembly.

A lateral stabilizer bar is arranged on one side of the hanger bracket assembly.

The lateral stabilizer bar is connected to the subframe welded assembly through a fixing bracket.

Swing Arm Structure

The upper swing arm assembly and lower swing arm assembly have the same structure.

The upper swing arm assembly is designed as a stamped and welded component with a hollow middle section, featuring:

Simple structure

Reduced weight

Convenient assembly

Limiting Block

A limiting block is arranged on the frame directly above the drive axle to limit the minimum body height.

This prevents the frame from pressing against the tires when the air springs lose pressure, ensuring the vehicle can still operate normally without tire rubbing.

Lateral Thrust Rod

A lateral thrust rod is arranged on the drive axle.

One end of the lateral thrust rod is connected to the drive axle, while the other end is connected to the frame.

This structure prevents excessive lateral body roll during turning, thereby reducing rollover risk and improving ride comfort.

Shock Absorber Assembly II

Shock absorber assembly II includes:

Shock absorber II

Upper mounting bracket

Shock absorber II is connected to the frame through the upper mounting bracket.

Air Spring Assembly II

Air spring assembly II includes:

Air spring II

Upper mounting bracket

Air spring II is connected to the frame through the upper mounting bracket.

Beneficial Effects

Compared with the prior art, the present invention has the following advantages:

All components of the front and rear air suspension assemblies are bolted to the frame, facilitating installation and maintenance.

The air spring assemblies can adjust the vehicle body height.

The shock absorbers effectively buffer forces acting on the frame.

The overall structure provides better stability.

Passenger riding experience and comfort are significantly improved.

Working Principle

During operation of the sightseeing vehicle, the height valve controls inflation and deflation of the air springs to adjust vehicle body height.

The shock absorbers buffer forces acting on the frame.

The steering mechanism controls wheel steering.

All components of the front and rear air suspension assemblies are bolted onto the frame, making installation, disassembly, and subsequent maintenance more convenient.
