Abstract
A wheel-guiding forward axle spring strut includes a spring and a shock absorber (6) integrated axially therein. The spring includes two end members (8, 10) and a spring element is disposed between these end members. The shock absorber (6) includes a shock absorber cylinder (20) and a shock absorber rod (18) connected to the chassis (24) via a non-rotatable shock absorber bearing (22) The end member (8) is connected by a rotational bearing (28) to the chassis. The lower spring end member (10) is fixedly connected to the shock absorber cylinder (20) and thereby in common to the forward axle. The upper spring end member is an air spring cover and the lower spring end member is an air spring piston (10) and an air spring flexible member (12) is mounted between the cover (8) and the piston (10) so as to be pressure-tight and tension-tight. The bearing (28) and a seal (30) are arranged between the air spring cover (8) and the non-rotatable component The bearing (28) and the seal (30) can be loaded in rotation in correspondence to a wheel moved to steer a vehicle.
