Rack-limiting and encoding type measurement driving simulator steering device

Abstract

A driving simulator steering device with rack limit and coded measurement, which includes a steering wheel, a rotating shaft, first and second bearings, bearing sleeves, bearing sleeve fixing plates, first, second, and third gears, steering Device frame front plate, bottom plate, left side plate, right side plate, encoder, motor, rack, steering gear frame front plate, bottom plate, left side plate and right side plate constitute the steering gear frame body, bearing sleeve, bearing sleeve The tube fixing plate and the first and second bearings are used to install the rotating shaft. The steering wheel, the first and the third gear are sequentially sleeved on the rotating shaft. The rack is arranged on the steering device frame body and meshes with the third gear. The motor is installed on the front plate of the steering gear frame, the second gear is installed on the front output shaft end of the motor and meshes with the first gear, and the encoder is installed on the rear output shaft end of the motor. The third gear and the rack realize limit, the motor realizes vibration and return to alignment, and the encoder is used for angle measurement. The steering device has good hand feeling, simple structure and low cost.

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...

AI Technical Summary

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

But the unavoidable disadvantages of these two patents are: (1) the motor drive is connected by gears and belts, the gear ratio is small, and only a relatively high-power motor can be used to obtain better driving force, and the belt is easy to age, which makes the cost high

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

(3) The gear scaling is used in the measurement of the rotation angle, and the rotation of the steering wheel for about three turns is zoomed into the measurement of the rotation angle of about one turn, which reduces the measurement accuracy

[0011] To sum up, although the driving simulator steering device provided in the prior art can also provide basic functions such as return to alignment and limit angle measurement, it cannot provide better safety, feel, and higher corner accuracy, or It will inevitably waste a lot of space, resulting in technical problems such as large steering device size and inconsistent left and right return forces, and poor user experience
