Background technique

At present, the widely used suspension structure in light truck field is the suspension system with shock absorber and leaf spring, but the shock absorber assembly with coil spring structure has not been applied in trucks yet. The traditional suspension system with shock absorbers and leaf springs is used in non-independent suspensions. The wheels on both sides are connected by an integral frame, and the wheels and axles are suspended under the frame through leaf springs. Its comfort and handling The stability is poor.

As shown in Figure 5, the existing light truck suspension structure mainly consists of front shock absorber assembly, leaf spring assembly, front buffer block assembly and other components. The shock absorber and leaf spring are connected to the axle and frame respectively. , Play the role of shock absorption and body load on light trucks.

Utility model content

Aiming at the deficiencies of the existing technology, the technical problem to be solved by the utility model is to provide a front suspension structure suitable for light trucks, so as to achieve the purpose of improving the comfort and handling stability of the truck.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

The front suspension structure suitable for light trucks includes a vehicle frame, a front shock absorber assembly, and a lower swing arm assembly. The front shock absorber assembly includes a shock absorber and a coil spring sleeved on the shock absorber, The upper end of the front shock absorber assembly is connected with the vehicle frame, and the lower end of the front shock absorber assembly is hinged with the lower swing arm assembly.

It also includes an upper swing arm assembly, and the upper end of the front shock absorber assembly passes through the upper swing arm assembly.

The upper end of the shock absorber is provided with a top plate for clamping the coil spring, and the top plate is provided with bolts for connecting with the vehicle frame.

The shock absorber is a two-way cylindrical shock absorber.

The lower end of the shock absorber is provided with a rotating shaft that can rotate relative to the shock absorber body, and the rotating shaft is connected with the lower swing arm assembly.

Compared with the prior art, the utility model has the following advantages:

The suspension structure makes the wheels on each side are independently suspended on the frame through the elastic suspension, and the left and right wheels jump independently, which can reduce the tilt and vibration of the vehicle body; the weight is light, and the body is reduced The shock and improve the ground adhesion of the wheel; the coil spring is used to improve the comfort of the car; the position of the engine can be lowered, and the center of gravity of the truck can also be lowered, thereby improving the driving stability of the car.

Detailed ways

The specific implementation of the present utility model will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

As shown in Figure 1 to Figure 4, the front suspension structure suitable for light trucks includes frame 1, steering knuckle with brake assembly 2, front shock absorber assembly 3, upper swing arm assembly 4, lower swing arm assembly 5. The front stabilizer bar assembly 6, wherein the front shock absorber assembly 3 includes a shock absorber 301 and a coil spring 302 sleeved on the shock absorber.

The shock absorber 301 is a two-way cylindrical shock absorber. The two-way cylindrical shock absorber generates damping force during the compression and extension strokes to accelerate the attenuation of the vibration of the vehicle frame and the vehicle body, so as to improve the ride comfort of the vehicle. The two-way cylinder shock absorber consists of two sections, the upper cylinder and the lower cylinder, which are nested together. The lower end of the helical spring 302 is fixed on the support plate on the lower cylinder of the shock absorber, and the upper end of the helical spring is connected to the top plate arranged at the upper end of the shock absorber. With coil springs, the position of the engine can be lowered, and the center of gravity of the truck can also be lowered, thereby improving the driving stability of the car.

The top plate of the shock absorber 301 is provided with three bolts for connecting with the vehicle frame. The frame 1 is provided with three installation holes corresponding to the three bolts. The upper end of the front shock absorber assembly passes through the upper swing arm assembly and is fixed through the installation holes by bolts. It is fastened with three lock nuts, and the three lock nuts Tighten to the torque required by the process.

The lower end of the front shock absorber assembly 3 is hinged with the lower swing arm assembly. Specifically, the lower end of the shock absorber is provided with a rotating shaft that can rotate relative to the shock absorber body, and the rotating shaft is connected with the lower swing arm assembly.

The steering knuckle belt brake assembly 2 is arranged on the lower swing arm assembly, and the front stabilizer bar assembly 6 is arranged between the left and right lower swing arm assemblies.

During the driving process of the whole vehicle, the bump shock absorber of the whole vehicle is compressed and stretched, and a damping force is generated to accelerate the attenuation of the vibration of the frame and the body, and play a role in damping vibration to improve the ride comfort of the car; At the same time, the coil spring of the shock absorber assembly replaces the role of the leaf spring to provide structural support for the vehicle suspension, so that the wheels on each side are individually suspended on the vehicle frame through elastic suspensions.

The front shock absorber assembly with coil springs is light in weight, which reduces the impact on the body, improves the ground adhesion of the wheels, lowers the position of the engine, and lowers the center of gravity of the truck, thereby improving the driving stability of the light truck.

The utility model has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited by the above-mentioned method, as long as various insubstantial improvements made by the idea and technical solutions of the utility model are adopted, or there is no Those who directly apply the idea and technical solution of the utility model to other occasions through improvement are within the protection scope of the utility model.
