Abstract
In a motor-vehicle spring-strut support bearing for mounting a piston rod of the spring strut to a vehicle support element, the piston is mounted in the support element to a connecting element which is connected to the support element by an annular resilient spring element disposed between the connecting element and the support element and axial stops are provided including a spherically curved surface on the support element, which limit axial movement of the piston rod upon compression of the spring strut by a vehicle wheel in one direction and upon rebound of the wheel in the opposite direction, the arrangement providing a force-centering support of the spring strut piston rod on the spring strut support.
Claims7
A spring-strut support bearing for supporting a motor-vehicle spring strut on a vehicle body, comprising a spring strut shock absorber with a piston rod, a vehicle body support element via which the spring strut shock absorber is supported on the vehicle body, a connecting element mounted on said piston rod for connection to said vehicle body support element, resilient spring elements arranged between the connecting element and the support element and including, a first resilient spring element structure arranged radially between the connecting element and the support element, a second resilient spring element structure mounted on said piston rod and disposed adjacent a section of said support element so as to engage said support element to limit axial movement of said piston rod in one axial direction and a third resilient spring element connected to said piston rod and disposed adjacent a section of said support element so as to engage said support element to limit axial movement of said piston rod in the opposite axial direction, said support element section having an approximately spherical configuration with an opening through which said piston rod extends into said vehicle body support element, wherein the piston rod is connected to said connecting element.
