Rack-limiting and motor-driven driving simulation device steering device

Abstract

A driving simulator steering device with gear rack limit and motor drive, which includes steering wheel, rotating shaft, first and second bearings, bearing sleeve, bearing sleeve fixing plate, first, second and third gears, motor, Steering gear frame front plate, bottom plate, left side plate, right side plate, rack, angle measuring sensor. The front plate, bottom plate, left side plate and right side plate of the steering gear frame constitute the main body of the steering gear frame, and the bearing sleeve, the bearing sleeve fixing plate and the first and second bearings are used to install the rotating shaft, and the rotating shaft is sequentially sleeved with Steering wheel, first and third gears, the angle measurement sensor is arranged at the end of the rotating shaft, the second gear is installed at the front output shaft end of the motor and meshes with the first gear, and the rack is arranged below the third gear and meshes with the third gear . The third gear and the rack realize limit, the motor realizes vibration and return to alignment, and the angle measurement sensor is used for angle measurement. Angle measurement sensor can choose Hall angle sensor, potentiometer, photoelectric encoder and so on.

Description

technical field [0001] The invention relates to the technical field of driving simulators, in particular to a steering device for driving simulators. Background technique [0002] Driving simulator is a kind of teaching equipment for driving training. It uses virtual reality simulation technology to create a virtual driving training environment. Students can learn driving skills by interacting with the driving simulation software through the operating parts of the driving simulator. Using simulated driving technology to train new students can not only train new students safely and efficiently, but also has the characteristics of low cost, zero emission, and environmental protection; if the simulated driving training method is fully utilized, it will bring significant economic benefits and social benefits. Driving simulators usually include steering wheel, clutch, foot brake, accelerator, hand brake, turn signal, wiper, gear and other operating components. The mechanism con...

Problems solved by technology

But the unavoidable shortcoming of these two patents is: (1) when the steering wheel is near the center position, the deformation of the two springs is small, so that the return torque is small, making it difficult to automatically return to the center position when the steering wheel is near the center position

(2) The limit block and the limit knob take up a lot of space, making the steering device larger

(3) Two springs are used for back-to-center driving, which is costly, and the individual differences of the two springs may easily lead to inconsistencies in the right-to-left back-to-center force

[0009] To sum up, although the driving simulator steering device provided in the prior art can also provide basic functions such as back alignment and limit angle measurement, it cannot provide better safety and feel, or will inevitably waste a lot of space The technical problems such as large size of the steering device and inconsistencies in the left and right return force make the user experience poor
