Abstract

Provided is a drive simulator steering capable of offering a feeling of actually driving a car to a player. The steering for drive simulator of the present invention has a first screw shaft which is connectable to a steering wheel and rotatable around an axial line together with the steering wheel; a first nut which is fit on the first screw shaft and moves linearly in an axial direction of the first screw shaft with rotation of the first screw shaft; a second screw shaft which is connectable to a motor, in parallel with the first screw shaft and rotatable around the axial line; and a second nut which is fit on the second screw shaft, moves linearly in an axial direction of the second screw shaft with rotation of the second screw shaft 15 and is connected to the first nut.

Claims

1. A steering for drive simulator comprising:

a first screw shaft which is connectable to a steering wheel and rotatable around an axial line together with the steering wheel;

a first nut which is fit on the first screw shaft and moves linearly in an axial direction of the first screw shaft with rotation of the first screw shaft;

a second screw shaft which is connectable to a motor, in parallel with the first screw shaft and rotatable around the axial line; and

a second nut which is fit on the second screw shaft, moves linearly in an axial direction of the second screw shaft with rotation of the second screw shaft and is connected to the first nut.

2. The steering for drive simulator of claim 1, wherein a lead of the first screw shaft is greater than a lead of the second screw shaft.

3. The steering for drive simulator of claim 1, wherein a detector for detection a rotation angle of the first screw shaft is mountable on the first screw shaft.

4. The steering for drive simulator of claim 1, wherein the first nut is a first ball screw nut with a plurality of rolling elements arranged rotatably between the first ball screw nut and the first screw shaft, and the second nut is a second ball screw nut with a plurality of rolling elements arranged rotatably between the second ball screw nut and the second screw shaft.

5. The steering for drive simulator of claim 1, further comprising a stopper made of viscoelasticity material for limiting moving amounts of the first nut and the second nut in the axial direction.

6. The steering for drive simulator of claim 1, further comprising a linear motion guide for guiding at least one of the first nut and the second nut.

8. The steering for drive simulator of claim 2, wherein the first nut is a first ball screw nut with a plurality of rolling elements arranged rotatably between the first ball screw nut and the first screw shaft, and the second nut is a second ball screw nut with a plurality of rolling elements arranged rotatably between the second ball screw nut and the second screw shaft.

9. The steering for drive simulator of claim 2, further comprising a stopper made of viscoelasticity material for limiting moving amounts of the first nut and the second nut in the axial direction.

10. The steering for drive simulator of claim 3, further comprising a stopper made of viscoelasticity material for limiting moving amounts of the first nut and the second nut in the axial direction.

11. The steering for drive simulator of claim 4, further comprising a stopper made of viscoelasticity material for limiting moving amounts of the first nut and the second nut in the axial direction.

12. The steering for drive simulator of claim 2, further comprising a linear motion guide for guiding at least one of the first nut and the second nut.

13. The steering for drive simulator of claim 3, further comprising a linear motion guide for guiding at least one of the first nut and the second nut.

14. The steering for drive simulator of claim 4, further comprising a linear motion guide for guiding at least one of the first nut and the second nut.

15. The steering for drive simulator of claim 5, further comprising a linear motion guide for guiding at least one of the first nut and the second nut.

7. A drive simulator comprising:

an angle detector for detecting a rotation angle of the steering wheel;

a motor for giving a load to the steering wheel;

a display unit for displaying an image;

a simulation controller for changing the image displayed on the display unit based on a signal from an operation input part including the steering wheel;

a motor controller for controlling the motor based on the rotation angle detected by the angle detector; and

the steering for drive simulator having

a first screw shaft which is connectable to the steering wheel and rotatable around an axial line together with the steering wheel;

a first nut which is fit on the first screw shaft and moves linearly in an axial direction of the first screw shaft with rotation of the first screw shaft;
