Abstract: An electrically driven power steering apparatus is structured such that a large impact on a rack shaft occurs upon an impingement of a steering stopper, and, even when an axial force acting on a ball bearing of a presser member becomes zero, a rotation of the presser member is hindered by caulking c at a thin plate member. Therefore, the presser member does not slacken, and a predetermined axial force can be given again to the ball bearing when the impact dissipates. The thus structured power steering apparatus exhibiting, though the cost is low, an excellent shockproof characteristic and capable of preventing the bearing from coming off a ball screw nut, can be provided.

Abstract: In a steering device (200), a first motor (34a) operates in accordance with a steering operation of a steering handle (12), a first steering shaft (52) steers one of the pair of wheels (58), and a first conversion unit converts a rotation of a first rotor (31a) as a rotation element of the first motor (31a) into an axial-direction movement of the first steering shaft (52). A second motor (34b) operates in accordance with the steering operation of the steering handle (12), a second steering shaft (53) is separated from the first steering shaft (52) and steers the other of the pair of wheels (58), and a second conversion unit converts a rotation of a second rotor (31b) as a rotation element of the second motor (34b) into an axial-direction movement of the second steering shaft (53). A coupling unit (60) couples the first rotor (31a) and the second rotor (31b) together and cancels the coupling of the first rotor (31a) and the second rotor (31b).

Abstract: A steering system with an electric motor includes a hollow shaft through which a rod is passed, the rod being drivable in the longitudinal direction by the electric motor through a worm gear. An intermediate transmission is provided, which reduces the rpm of the electric motor. The hollow shaft is connected torque-proof with a driving outer contour, which transfers torque to the intermediate transmission. The intermediate transmission has a first gear wheel, an axle of which is supported so as to be stationary, and the outer contour of which transfers torque. The worm of the worm gear is formed on the rod. A nut of the worm gear is drivable by the intermediate transmission. For greater economy of construction of the steering system, a second gear wheel with a torque-transferring outer contour, connected over an intermediate shaft torque-proof with the first gear wheel. The intermediate transmission transfers torque to an outer contour, which is connected torque-proof with the nut.
