Embodiment Construction

[0038] figure 1 depicts a wheel suspension system 100 according to one embodiment, which is locked and fastened by means of fastening screws 103 figure 1 The wheels are shown mounted to an axle beam 101 of the vehicle.

[0039] The wheel suspension system 100 comprises a traction element 105 which is non-rotatably engaged with the fastening screw 103 and which serves to subject the fastening screw 103 to torque, in particular to break it, so that the locking fastening is released. Thus, the fastening screw 103 provides a predetermined breaking point for the mechanical coupling.

[0040] The wheel suspension system 100 also comprises a control arm 107 which is attachable to the axle beam 101 by means of a fastening screw 103 and which is adapted to act on the traction element 105 during a rotational movement of the control arm 107 relative to the axle beam 101 in order to produce a Release the tightening torque of the lock. To this end, the traction element 105 is subjected ...

Abstract

The disclosure relates to a wheel suspension system for a wheel suspension on an axle beam of a vehicle using a fastening screw, including: an entrainment element non-rotatably joinable with the fastening screw and configured to apply a torque to the fastening screw to release a force-locking fastening; and a control arm configured to be attached to the axle beam by the fastening screw and configured to act on the entrainment element during a rotational movement of the control arm with respect to the axle beam to produce the torque to release the force-locking fastening.

Description

technical field [0001] The invention relates to a wheel suspension system with a control arm for suspending the wheels of a vehicle, in particular a motor vehicle, to an axle beam of the vehicle. Background technique [0002] In modern vehicles, control arms (often arranged as wishbones crossing about the longitudinal axle axis) are used to mount the wheels to the axle beams of the vehicle. [0003] In the case of a frontal impact (40% overlap with the control arm area) tested according to NCAP (NCAP: European New Car Assessment Program), or at 64 km / h according to IIHS (IIHS: Insurance Institute for Highway Safety) , with a small overlap of 25% with the control arm area, the stringers are used to convert impact energy into deformation energy. [0004] However, with less overlap than simulated by the NCAP test, the side beams could be missed, resulting in impact energy that could be transferred through the control arm to the axle beam. To solve this problem, additional rei...
