The invention relates to general motorized vehicles, special features an improved suspension * device, which the Fahrseugchassls is resiliently mounted on the old wheels in contact with the ground.

Xn some suspension ^ sy stones for motor vehicles 1st it is desirable that the front suspension system forming suspension devices, each of which is a Coil spring and a shock absorber included, to be arranged directly on each front wheel of the vehicle. Such a one Suspension is associated with associated rewards in U.S. Patent No. 2 624 592 described, which was issued to MacPherson and which all is known as the MacPherson system.

One of the disadvantageous side effects of this type of suspension device is that it has hitherto been necessary was to cover the greater part of the front of the vehicle

ierlogen and remove each wheel old of its axle, if the shock absorbers are removed after their parts have worn out and should be replaced. This is a free difficult and time-consuming process which requires special tools and skilled workers. Hence 1st a suspension device with the positive properties of the MtcPheraoa system, in which, however, the coatJlieierte There is no need for dismantling and re-installation processes for the shock absorber, very desirable.

The widened end 43 of the tube 45 is crimped below the outer bearing race 41 to hold the bearing 29 in place. The disk 49 is detachable in the. Groove 48 is arranged at the upper end of the sleeve 47 in order to prevent sehmuts , grease and other foreign matter from collecting over it and contaminating the bearing 29. The bushing 47 is connected to the vehicle frame 27 by an annular collar 51, which surrounds the bushing 47 and secures it and, as a natural formation, has a radially outwardly extending extension flange 53 which overlaps with the vehicle frame 27 and on it with the bolt 55 and the cutter 57 is attached.
