Abstract
In an electrically adjustable steering of the present embodiment, a first telescopic actuator is disposed between a top bracket or a mount bracket on a vehicle body side and a steering jacket. The steering jacket includes a plurality of jacket members that overlap each other so as to be able to expand and contract in an axial direction. A motor of the first telescopic actuator is fixed to the top bracket or the mount bracket on the vehicle body side.
Claims12
An electrically adjustable steering comprising:
- a top bracket mounted on a mount bracket on a vehicle body side;
- a steering shaft to which a steering wheel is connected;
- a steering jacket configured to be held by the top bracket and rotatably supports the steering shaft on an inner side;
- a first telescopic actuator configured to be disposed between the top bracket or a mount bracket on the vehicle body side and the steering jacket, and adjusts lengths of the steering shaft and the steering jacket by using a motor;
- and
- a tilt actuator configured to perform a tilting motion of inclining the steering jacket with respect to the top bracket, wherein
- the steering jacket includes first to third jacket members in order from the steering wheel side, and the first and second jacket members and the second and third jacket members overlap each other separately so that the steering jacket can expand and contract in an axial direction,
- the third jacket member is rotatably connected to the top bracket by a first pivot which is a center point at which the steering jacket rotates at the time of the tilting motion, and
- the motor of the first telescopic actuator is fixed to the top bracket or the mount bracket on the vehicle body side via a second pivot which is connected to the top bracket.

- a top bracket mounted on a mount bracket on a vehicle body side;
- a steering shaft to which a steering wheel is connected;
- a steering jacket configured to be held by the top bracket and rotatably supports the steering shaft on an inner side;
- a road surface reaction force generation device configured to transmit a road surface reaction force generated between a road surface and a road wheel to the steering wheel;
- and
- a first telescopic actuator configured to be disposed between the road surface reaction force generation device and the steering jacket, and adjusts lengths of the steering shaft and the steering jacket by using a motor;
