HYDRAULIC ACTUATOR OF STEERING WHEEL Russian patent published in 1994 - IPC

FIELD: automotive engineering. SUBSTANCE: central passage of casing 5 of actuator cut-off mechanism accommodates plunger 8 pivotally connected by levers 12, 13 to cylindrical rods 19, 20 positioned in symmetry with the axis of plunger 8 and linked to adjustment plugs 23, 24 received in threaded passages of casing 5. The levers carry rollers 33, 34 to engage with side faces of sector 4. In its end positions sector 4 exerts force through roller 33 and lever 12 on plunger 8 for the latter to move and communicate pressure chamber of distributor with discharge, disengage the actuator, and thereby limit the turning angle of steerable wheels of the vehicle. EFFECT: increased reliability in operation. 1 dwg
