Abstract
A dashpot for wheel suspensions, with a preferably sheet-metal spring cup (6). The cup is attached to a shock absorber or its accommodating tube, supports a helical spring that surrounds the shock absorber or tube, and can be advanced along the shock absorber or tube on threads. To allow the dashpot to be raised and lowered in precise increments, the attachment is maintained tight by a cylindrical housing (3). The housing is provided with a slot extending over its total length and with outside threads. Its inner surface of the housing rests directly against the shock absorber or its tube. The housing operates in conjunction with a height-adjustment ring (12) or neck (7) with matching inside threads on the spring cup. The slope of the threads ensure that the force exerted by the spring on the spring cup will squeeze the slotted housing together radially.
