Electric power steering device |
摘要 |
An easy-to-assemble electric power steering device, in which an approximately cylindrical housing is divided at about the central part into a first chamber and a second chamber. The first chamber is for housing a motor for assisting the steering force. A stator of the motor is inserted at one end of the housing and fixed. The second chamber is for housing a rack shaft assembly which comprises a rack shaft connected with the steering shaft and a ball screw mechanism. The rack shaft assembly is inserted at the other end of the housing, to thereby spline a rotor of the motor for assisting the steering force with a nut of the ball screw mechanism. A bearing supporting the nut of the ball screw mechanism is axially movably held in the inner wall of the second chamber. The rack shaft is arranged through the first and second chambers of the housing.
