Description

The driving simulator transfer that a kind of limit of rack and coding type measure

Technical field

The utility model is related to driving simulator technical field more particularly to driving simulator transfers.

Background technology

Driving simulator is a kind of teaching equipment of driver training, it builds virtual driving using virtual reality emulation technology Training environment, student is interacted by the operating member of driving simulator with drive simulating software, to learn driving efficiency. New student is giveed training using drive simulating technology, can not only train new student safe efficiently, and with it is at low cost, Zero-emission, environmentally protective feature；If making full use of drive simulating training method, significantly economic benefit and society can be brought It can benefit.Driving simulator generally includes the operations such as steering wheel, clutch, service brake, throttle, parking brake, steering indicating light, windscreen wiper, gear Component.The mechanism being connected with steering wheel is transfer, it be in all operating members of automobile simulator most it is complicated also the most The fidelity of important operating member, transfer will directly affect experience of the user to entire automobile simulator.Usually, Transfer in driving simulator needs following function：Limit is returned just and outer corner measurement, if to obtain better body It tests, usual transfer can also increase vibrating function.

Limit：In general, its rotational angle is restricted when driving simulator steering wheel rotates, ± 720 are generally included Degree（I.e. therefrom position starts to take two turns to the left or to the right steering wheel）With ± 540 degree（I.e. therefrom start can be to for position for steering wheel A left side is turned around to the right partly）Two kinds.

Hui Zheng：In the driving process of vehicle, if steering wheel has rotated certain angle, steering wheel can self-aligning To middle position.

Outer corner measurement：In order to enable drive simulating program links with steering wheel, the angle of rotation for knowing steering wheel at any time is needed Degree, therefore just need installing angle measurement sensor on the steering wheel.

Vibration Simulation：When vehicle encounters the abnormal conditions such as bumpy road, collision in simulating driving procedure, steering wheel will produce Vibration.

Existing common driving simulator transfer is described below：

In the prior art, the pinion and-rack car steering mould with reference to described in Chinese patent ZL201520879731.8 Quasi- device transfer, utilization orientation column, universal joint and rack-and-pinion are coordinated, and are tooth by the convert rotational motion of steering wheel The linear motion of item, and during rack linear moves, the compressed capability based on the spring being arranged on worm screw so that turn to Device realize back just with limit, meanwhile, coordinate the first rivet and the second rivet to make the bar magnet on drive rod in straight line Magnetic field changes in motion process, leads to the voltage change of hall device, realizes the function that steering wheel angle measures；Although should Scheme can also realize automobile driving simulator return just, limit and the basic functions such as angle measurement, but due to worm screw resistance It is larger, it needs to coordinate larger spring that could return positive direction disk, causes steering wheel return positive force excessive, safety and feel are poor.

Positive automobile driving simulator is mechanically returned with reference to described in Chinese patent ZL201420372533.8 turns to dress It sets, when steering wheel rotates, rotary shaft rotation has been driven by gear cooperation rotation, and then driven limit rotating handle, first Bar magnet and the rotation of the second bar magnet, when rotation touches limited block to limit rotating handle to the left or to the right, steering wheel can not It is rotated further, here it is the limit functions of steering wheel.In rotary course, two springs in rotary shaft can be also supplied to side To the torque of one self-aligning of disk, realize steering wheel self-aligning, when the first bar magnet and the second bar magnet rotate with The relative angle of Hall angular transducer changes, to export different voltage values, to realize outer corner measurement.Meanwhile The dual spring with reference to described in Chinese patent ZL201520224226.X returns positive automobile driving simulator transfer, in State's patent ZL201420372533.8 implementations are substantially similar, improve the installation site of spring, convenient for being torn open to spring Dress.But this two inevitable disadvantages of patent are:（1）When steering wheel is near center location, the deformation of two springs It is smaller, keep aligning torque smaller, makes steering wheel is more difficult near center location to automatically return to center position.（2）Limited block and It limits rotating handle and occupies larger space, keep transfer volume larger.（3）Use two springs carry out back just drive, cost compared with Height, it is inconsistent to positive dynamics is returned that the individual differences of two springs easily leads to left and right.

Hall sensing and motor-driven driving simulation with reference to described in Chinese patent ZL201420372533.8 Non-contact Angle Measurement and motor-driven automobile mould described in transfer and Chinese patent ZL201520634318.5 Quasi- device transfer, this two patents all use gear structure, keep feel preferable；Motor driving is all used to turn to realize Returning just and vibrating function for device, keeps rotating torque adjustable；It all uses noncontacting proximity sensor and realizes outer corner measurement function.But It is that this two inevitable disadvantages of patent are:（1）Motor driving is connected using gear and belt, and gear no-load voltage ratio is small, can only Preferable driving force could be obtained with the motor of relatively high power, belt is easy to aging, makes of high cost.（2）Limited block and limit rotating handle Larger space is occupied, keeps transfer volume larger, it is of high cost.（3）It uses gear when outer corner measurement to scale, the three of steering wheel The rotation of circle left and right is scaled to the outer corner measurement of circle or so, and measurement accuracy is made to become smaller.

To sum up, although the driving simulator transfer provided in the prior art can also provide it is basic as return just, limit The functions such as angle measurement, but preferable safety, handling property, higher corner accuracy can not be provided, or necessarily waste larger Space so that transfer volume is larger and to control back technical problems, the user experiences such as positive dynamics is inconsistent poor.
