Project introduction:
Rising energy costs require improving the efficiency of the transportation industry, and lightweight technology can achieve this.
Because the allowable total weight of multi-purpose vehicles is limited by law, the reduction of chassis weight can directly improve the potential payload capacity. Wheel alignment is a key factor affecting driving stability and tire wear. However, the chassis structure design is closely related to some boundary conditions. Mechanical requirements must be met, such as the ability to withstand bending moments (especially at the tail). The position of the suspension element must meet the requirement of keeping the running height low. Due to the high cost and the existing chassis design, the use of modern composite materials to reduce weight often fails. Minimizing the production tolerance can further reduce the cost. However, it may need to adjust the chassis after production, and it will generate a lot of extra costs.
The cooperators from hildesheim/Holzmingden/Gö ttingen University of Applied Sciences have developed a rigid, driveless and mechanically robust chassis, which is suitable for multi-purpose vehicles with great light weight advantages. The chassis structure comprises a lower transverse strut and an upper transverse strut, which are fixedly connected with each other through a connecting piece, wherein at least one of the brake flange and the axle trunnion is integrated in the connecting piece. The upper transverse strut has two grooves, which limit the space above the lower transverse strut. This space structure is specially designed for the favorable installation of suspension elements, which are embodied as air suspension bellows. In a special structural layout, the axle body and swing arm of the chassis adopt skeleton design with multiple pillars. Seen from the side view, the chassis structure is L-shaped, in which one leg of the L-shape consists of a horizontal structural part forming a longitudinal swing arm. The chassis is mainly designed to transmit pressure and tension, while avoiding most bending moments. The annular upper bracket allows the suspension element to be placed near or even directly above the axle, so that the force can be directly transmitted to the suspension system, while the lowered lower bracket can keep the overall height low. Design technology of commercial vehicle chassis structure The axle load is at least 7000 kg and the mass is less than 130 kg.
superiority
Compared with the traditional chassis design, the weight advantage is obvious.
Can be produced using carbon fiber reinforced materials.
Lightweight structure saves energy and fuel.
Adjustable upper cross brace enables cost-effective built-in wheel alignment.
The height and tare weight are low, and the payload is increased.
By transmitting the force directly into the suspension, the suspension performance is optimized.
Unsprung weight is minimized to reduce wear and tear.
app; application
Trucks, trailers and buses
Because the motor is easy to be integrated near the hub, it is more suitable for electric vehicles.
