Problems solved by technology

Due to the horizontally oriented ends and due to the inclined central connection, this structural design of the leaf spring is rather complicated, since the direction of force action in the area of ​​the central connection changes when springing vertically in the Z-direction. results in a force component in the Y-direction

Embodiment Construction

[0027] figure 1 Shows a schematic diagram of the axle, here shown as an integral axle of the rear axle (rear axle) of the vehicle. Integral axles are characterized in that the track, toe-in and camber are always constant for the driving road and generally provide good lane safety. Manufacturing costs are low. However, under the influence of the lateral force FS acting in the Y-direction, unfavorable deformations of the leaf spring can occur if the leaf spring is not made of steel but of fiber-reinforced plastic.

[0028] According to the present invention, figure 1 The steel leaf springs shown in are replaced by leaf springs made of glass fiber composites and carbon fiber composites (GFK / CFK). figure 2 Such a leaf spring 1 is shown. The leaf spring has a three-layer structure with an upper layer 2 made of GFK and a lower layer 3 made of GFK. A reinforcement part 4 made of CFK is arranged between the upper and lower layers 2 , 3 . refer to figure 2 It can be seen that ...

Abstract

In a leaf spring arrangement for a chassis of a motor vehicle, a leaf spring includes multiple layers made of a glass fiber composite plastic, a reinforcement made of a carbon composite plastic and being disposed between an upper and a lower one of the layers, and a core made of a different material than the reinforcement and being disposed between the upper and lower layers, wherein the reinforcement is arranged along a longitudinal a side of the core. The leaf spring is coupled at its center region to an axle of the motor vehicle by a center connection and to the vehicle body by bodywork connections, wherein the leaf spring is tilted by an angle relative to the vertical axis of the motor vehicle.

Description

technical field [0001] The invention relates to a leaf spring arrangement for a chassis of a motor vehicle. Background technique [0002] The elastic shock absorption and buffer damping system of the automobile especially first acts on the vehicle vibration in the vertical direction. The design of the elastic damping system is decisive for driving comfort, that is to say, for the vibration loads of the vehicle's passengers and transported goods. In addition, elastic damping systems also have a decisive influence on driving safety. Leaf springs are known elastic damping elements which are used both in passenger vehicles (PKW) and in the field of commercial vehicles. Leaf springs are designed as single-layer or multi-layer, and in some applications can also undertake the function of wheel guidance. They can advantageously introduce forces into the body. Leaf springs made of steel have a considerable weight. Even in the area of ​​commercial vehicles, however, the greatest ...
