Description

一方、本発明のトルク伝達用継手及び電動式パワーステアリング装置のうち、請求項７に記載した電動式パワーステアリング装置の発明は、ハウジングと、操舵用回転軸と、ウォームホイールと、ウォームと、電動モータと、トルク伝達用継手とを備える。
このうちのハウジングは、固定の部分に支持されて回転する事がない。
又、前記操舵用回転軸は、前記ハウジングに対し回転自在に設けられて、ステアリングホイールの操作により回転させられ、回転に伴って操舵輪に舵角を付与する。
又、前記ウォームホイールは、前記ハウジングの内部で前記操舵用回転軸の一部に、この操舵用回転軸と同心に支持されて、この操舵用回転軸と共に回転する。
又、前記ウォームは、ウォーム軸の軸方向中間部にウォーム歯を設けて成り、このウォーム歯を前記ウォームホイールと噛合させた状態で、前記ウォーム軸の軸方向両端部をそれぞれ軸受により前記ハウジングに対し回転自在に支持されている。
又、前記電動モータは、前記ウォームを回転駆動する為のものである。
更に、前記トルク伝達用継手は、前記電動モータの出力軸と前記ウォーム軸との間に設けられて、これら両軸同士の間でトルクを伝達するもので、上述の様な、本発明のトルク伝達用継手である。 On the other hand, among the torque transmission joint and the electric power steering apparatus according to the present invention, the electric power steering apparatus according to the seventh aspect of the invention includes a housing, a rotating shaft for steering , a worm wheel, a worm, and an electric motor. A motor and a torque transmission joint are provided.
Of these, the housing is supported by a fixed portion and does not rotate.
The steering rotation shaft is rotatably provided with respect to the housing and is rotated by an operation of a steering wheel, and gives a steering angle to the steered wheels as it rotates.
The worm wheel is supported on a part of the steering rotation shaft inside the housing, concentrically with the steering rotation shaft, and rotates together with the steering rotation shaft.
The worm is formed by providing worm teeth at an axial intermediate portion of the worm shaft. With the worm teeth meshed with the worm wheel, both axial end portions of the worm shaft are respectively attached to the housing by bearings. On the other hand, it is supported rotatably.
The electric motor is for rotating the worm.
Further, the torque transmission joint is provided between the output shaft of the electric motor and the worm shaft, and transmits torque between the two shafts. This is a transmission joint.
