Embodiment Construction

[0069] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

[0070] figure 1 It is a schematic diagram showing a schematic configuration of an electric power steering device 1 serving as a steering device for a vehicle according to an embodiment of the present invention.

[0071] refer to figure 1 The electric power steering device 1 is provided with: a steering wheel (steering wheel) 2 as a steering member; a steering mechanism 4 that steers the steering wheel 3 in conjunction with the rotation of the steering wheel 2; and a steering auxiliary mechanism 5 that 5 is used for assisting the steering of the driver. The steering wheel 2 and the steering mechanism 4 are mechanically connected via a steering shaft 6 and an intermediate shaft 7 .

[0072] In this embodiment, an example in which the steering assist mechanism 5 provides assist force (steering assist force) to the steering shaft 3 is described, but the pres...

Abstract

Disclosed is a vehicle steering device (1; 301) equipped with a control device (12; 322) which controls the actuation of an electric motor (18; 317). First and second housings (23, 24 325, 312), which are in contact with each other, partition off a chamber (100; 324) which contains the control device (12; 322). The first housing (23; 325) is at least one part of the motor housing (25; 323). The first housing (23; 325) includes a first interior wall surface (101; 401) which partially partitions the chamber (100; 324). The second housing (24; 312) includes a second interior wall surface (102; 402) which partially partitions the chamber (100; 324). The first and the second interior wall surfaces (101, 102; 401, 402) are opposite each other with respect to the axial direction (X1) of a rotating shaft (37; 352) of an electric motor (18; 317). The second interior wall surface (102; 402) includes the flat annular surface that surrounds a central axis line (C1) of the rotating shaft (37; 352)and an extension (C2) of the central axis line (C1). The flat circular surface is orthogonal to the central axis line (C1) and the extension (C2) of same.

Description

technical field [0001] The present invention relates to a vehicle steering device. Background technique [0002] An electric power steering device, which is a steering device for a vehicle, uses an electric motor to assist a driver in steering. That is, various sensors detect the steering state of the steering member, etc., and the control device controls the electric motor based on the detection results of the steering state, thereby imparting steering assist force to the steering mechanism. [0003] A technique has been proposed in which a control device is disposed between the electric motor and the reduction mechanism in the axial direction of the electric motor (for example, refer to Patent Documents 1 to 4). [0004] Furthermore, it has been proposed to dispose an electric power steering device housing a control device at a position opposite to the reduction mechanism in the axial direction of the rotation shaft of the electric motor within the housing of the electric...
