Embodiment Construction

[0042] In the different figures, identical components are always given the same reference numerals and are therefore usually only described once.

[0043] figure 1 A first embodiment of a suspension system 1 according to the invention is shown, which may be used eg for a truck or a minivan. An axle 3 configured as a rigid axle and extending parallel to the Y axis is fixed via an intermediate element 7 to a leaf spring 2 extending substantially in the direction of the X axis. By means of leaf springs 2 made of fibre-reinforced plastic material, the axle 3 is elastically fixed to a vehicle structure 20 (in this case a highly schematic schematic diagram), such as a frame. Of course, a total of two leaf springs 2 symmetrically arranged on both sides of the vehicle are provided. Of course, in this case a wheel (not shown) is arranged rotatably on the end side of the axle 3 . In this case, the leaf spring 2 forms a leaf spring unit, which can optionally also be constructed as an ...

Abstract

The invention relates to a suspension system (1) having a leaf spring unit (2) comprising composite material and extending along the longitudinal vehicle axis (X) and connected at the front end (2.1) to the vehicle structure (20) and has a connection area (2.3) for the axle (3) and has a connection arm (4) which is on the one hand pivotably connected to the rear end (2.2) of the leaf spring unit, and Another aspect is pivotally connected to a vehicle structure (20). In order for the wheel suspension to have a longitudinal leaf spring with reduced stiffness in the longitudinal direction and at the same time retain the stiffness in the transverse direction to the greatest possible extent, it is disclosed according to the invention that the leaf spring unit (2) is rigidly connected at the front end (2.1) to The vehicle structure (20) and has a longitudinal elastic portion (2.5) between the front end (2.1) and the connection area (2.3), the longitudinal elastic portion (2.5) having at least two separate portions (2.6- 2.9).

Description

technical field [0001] The invention relates to a suspension system having the features of the preamble of claim 1 with a leaf spring unit comprising composite material and extending along the longitudinal vehicle axis and connected at the front end to the vehicle structure, the leaf spring unit having a connection area of ​​the axle and a connecting arm which is pivotably connected on the one hand to the rear end of the leaf spring unit and on the other hand to the vehicle structure. Background technique [0002] In motor vehicles, different suspensions are known for the wheels of the vehicle. In particular, a distinction can be made between single-wheel suspensions, which are now almost exclusively used on passenger cars, and fixed-axle suspensions, which are mainly used on the rear axle of utility vehicles. In the latter suspension, the wheels on either side rest on a single continuous axle, usually elastically mounted relative to the vehicle structure by leaf springs or...
