Servo steering, particularly power steering for vehicle, has leading screw powered by servo actuator and is made of axially non-relocated nut supported in rack and axially shifted component

摘要

The servo steering (1) has a leading screw (3) powered by a servo actuator (2) and is made of an axially non-relocated nut (5) supported in a rack (4) and an axially shifted component (6), whose thread (7) is in interference with a nut thread (8) of the nut. The axially shifted component is formed as pipe (9) or pipe shaped. The axially shifted component is made of different steels. The rack is formed as steering gear housing (10) made of a high-strength aluminum copper zirconium alloy or aluminum zinc magnesium alloy or titanium alloy.
