<p>Hydraulic actuator for turning movement of a knuckle, especially a steering knuckle, a torus shaped guiding path for pistons (4, 5) comprising a carrier ring (3) connected to the knuckle (8), the carrier ring (3) thereby establishing the inner circumference of the path and being sealingly moveable against a lower part (2) and an upper part (1) which is secured to the lower part and which together establish the rest of the path and being stationary, at least one piston (4) being sealingly displaceable in the guiding path and fixed to the carrier ring (3) and at least one fixed piston (5) secured to the lower part (2), whereby channels (9, 10) establish input and output for hydraulic fluid to diametrically opposed spaces between a displaceable piston (4) and a fixed piston (5), the carrier ring (3) being connected turnable with the steering knuckle (8) and displaceable in the axis direction thereof by means of two diametrically opposed pins (7) connected with the knuckle (8), received in corresponding bearing linings in the inner circumference of the carrier ring.</p> |
