Car driving simulator steering device straightened using single spring

Abstract

The invention provides a steering device for a car driving simulator with a single spring returning to normal, which comprises a steering wheel, a first rotating shaft, a first gear, a triangular limit block, a rotating damper, a second rotating shaft, a second gear, a spring , Triangular limit knob, angle measurement sensor. The invention can realize the functions of position limiting, centering and rotation angle measurement of the steering wheel. The rotary damper is used to reduce the speed of the steering wheel returning to the center, so as to obtain a better steering wheel feel and more safety. A spring is used to return the steering wheel, and the return effect is good, the structure is simple, and the cost is low. The spring is sleeved on one end of the second rotating shaft, which is convenient for disassembly and replacement. The angle measurement sensor can use a Hall angle sensor, a potentiometer, a photoelectric encoder, an angular displacement sensor, etc., to measure the steering wheel angle. The limit knob and the limit block are used to realize the limit function of the steering wheel, and a triangular structure is adopted, the contact area is large, and the limit block is not easy to be damaged.

Description

technical field [0001] The invention relates to the technical field of automobile driving simulators, in particular to a single-spring returning steering device for automobile driving simulators. Background technique [0002] Car driving simulators usually include steering wheel, clutch, foot brake, accelerator, hand brake, turn signal, wiper, gear and other operating components. The mechanism connected with the steering wheel is the steering device, which is the most complex and important operating part among all the operating parts of the car driving simulator. The simulation degree of the steering device will directly affect the user's experience of the entire car driving simulator. Generally speaking, the steering device in the car driving simulator needs to have the following functions: limit, return and angle measurement. If you want to get a better experience, usually the steering device can also increase the vibration function. [0003] Limit: Usually, when the s...

Problems solved by technology

However, the structure of this steering device is more complicated and the cost is higher.

[0010] Existing solution 3: Chinese patent 201420372533.8 discloses a mechanical steering device for a car driving simulator. Although the steering wheel of this patent has a better feel and is cheaper than the above two solutions, the disadvantages are: (1) The structure is relatively Complex, high cost, very inconvenient to disassemble and maintain the spring; (2) The limit block is often made of plastic cylinders, and the limit knob is often made of thicker iron sheets. The contact part between the two is a line segment, and the contact area is small , when the pressure is the same, the pressure of the contact part
