ABSTRACT:
A stabilizer bar unit for an automobile includes a stabilizer bar connected to the control arms of two aligned wheels of the automobile at two ends thereof. A cylindrical sleeve coaxially surrounds the intermediate portion of the bar in such a manner that two sealed annular chambers are formed in two end portions of the sleeve. Two movable rings are received movably within the chambers and have splined inner surfaces engaged with the splined outer surface of the intermediate portion of the bar, and splined outer surfaces engaged with the splined inner surface of the sleeve. The piston rod of a pivotally mounted hydraulic cylinder is connected rotatably to the sleeve. A hydraulic liquid is supplied from a reservoir to the cylinder through a conduit unit. An automatically controlled switch is disposed on the conduit unit so as to stop the intercommunication between the reservoir and the cylinder when the automobile is steered, accelerated or braked. An automatic control system moves the rings outward in response to the increase in the rotational speed of the wheels and moves the rings inward in response to the reduction of the rotational speed of the wheels. The portion of the bar between the rings cannot be twisted.
