Embodiment Construction

[0032] Figure 2 to Figure 6 A first exemplary embodiment of a vehicle axle arrangement 1 is shown with a wheel carrier 12 and with a transverse leaf spring extending substantially in the vehicle transverse direction y in the installed position and guiding the wheels connected to the wheel carrier 12 13 and the shock absorber strut 3 that is coupled with the wheel frame 12 and guides the wheel, wherein the transverse leaf spring 13 is in contact with the figure 2 The vehicle side opposite to the vehicle side shown in the figure is likewise connected to other wheel carriers not shown in detail in the drawings in the form and manner described in detail below.

[0033] Furthermore, the wheel 2 is fixed on the wheel carrier 12 and the spring strut 3 is arranged on the vehicle body side in the region of the end 7 of the piston rod 5 . The connection region 14 between the transverse leaf spring 13 and the wheel carrier 12 is spaced apart from the resulting force application point 6...

Abstract

A vehicle axle device (1) comprises a wheel frame (12), at least one transverse plate spring (13) basically extending on the vehicle horizontal direction (y) from the installation position and connected with the wheel frame (12) for guiding wheels, and at least one buffering column (3) connected with the wheel frame (12) and guiding wheels. The connection area (14) between the transverse plate spring (13) and the wheel frame (12) is at least spaced on the vehicle horizontal direction (y) with the force exerting point (6) generated by a tyre contact force (F2) exerting on the wheel (2) area. The device provided in the invention further comprises an apparatus through which the following force can be introduced into an area among the wheel frame (12), the transverse plate spring (13) and the buffering column (3). Through the force, the torque exerting on the wheel frame (12) and to be supported on the vehicle side adjacent to the buffering column (3) can be at least partially offset.

Description

technical field [0001] The invention relates to a vehicle axle arrangement according to the type defined in detail in the preamble of patent claim 1 . Background technique [0002] From US 6530587B2 a vehicle axle arrangement or a McPherson wheel suspension is known, which consists of the following devices: a longitudinal control arm for absorbing longitudinal forces; and lateral control arms to absorb lateral forces; shock struts to guide the wheels; and transverse leaf springs to guide the wheels and fulfill the function of the suspension spring and stabilizer. [0003] A major problem with wheel suspensions with wheel-guiding transverse leaf springs and wheel-guiding damping struts is the torque introduced into the vehicle's axle system via the vertical force lever arm, which is connected to the Projected onto a plane spanned by the vehicle transverse direction and the vehicle longitudinal direction, the distance between the spring force and the wheel contact force corre...
