Description
technical field:
The utility model relates to automobile driving simulator technical field, is specifically related to a kind of mechanical type and returns positive automobile driving simulator steering gear.
background technology:
Automobile driving simulator generally includes the functional units such as bearing circle, clutch coupling, service brake, throttle, parking brake, steering indicating light, windscreen wiper, gear.The mechanism be connected with bearing circle is steering gear, and it is the most complicated also of paramount importance functional unit in automobile driving simulator all operations parts, and the fidelity of steering gear will directly affect the experience of user to whole automobile driving simulator.As a rule, the steering gear in automobile driving simulator needs following function: spacing, returning just and outer corner measurement.If obtain better experience, usual steering gear can also increase vibrating function.
Spacing: time vehicle steering rotates usually, to have rotational angle to limit, generally include ± 720 degree (namely bearing circle can take two turns left, also can take two turns to the right), ± 540 degree (namely bearing circle can turn around half left, also can turn around half to the right).
Hui Zheng: in the driving process of vehicle, if the certain angle of rotating of steering wheel, then bearing circle can self-aligning to meta.
Outer corner measurement: in order to make drive simulating program and bearing circle link, needing the rotational angle knowing bearing circle at any time, therefore just needing installing angle survey sensor on the steering wheel.
Vibration Simulation: in simulating driving procedure, vehicle runs into the sensation of bearing circle when jolting road surface.
Existing common automobile driving simulator steering gear is below described:
Existing scheme 1: bearing circle is provided with a centre rotational axis, centre rotational axis is provided with steering wheel (i.e. worm gear device), thus be rectilinear motion by the convert rotational motion of bearing circle, on the axle both sides of rectilinear motion, spring is installed, for steering wheel return just.In addition, the one end on the axle of rectilinear motion, is provided with linear displacement transducer.At the two ends of linear axis, two limit screw caps are installed, for the range of movement of straight limit axle, thus limit the rotational angle of bearing circle.The advantage of this scheme is less demanding to installation accuracy, and production cost is comparatively cheap.Shortcoming is that worm and gear resistance is comparatively large, needs larger spring could return positive dirction dish, causes steering wheel return positive force excessive, security and feel poor.
Existing scheme 2: steering wheel shaft is provided with pinion wheel, and pinion wheel is connected with gear wheel, mounting limit device on gear wheel.Again by gear set, mounted motor and photoelectric encoder on steering wheel shaft.Wherein motor is used for providing steering wheel return positive force and Vibration Simulation, and photoelectric encoder is used for direction of measurement dish corner.The advantage of this scheme is the steering wheel angle precision that photoelectric encoder can provide very high, and numerical stability.Motor can provide comparatively uniform bearing circle counter-force, and feel is better, in addition, can be simulated the steering wheel vibration on road surface of jolting by control moment motor.Shortcoming requires higher to installation accuracy, and for portable simulator, adopt plastics die sinking accessory, can ensure installation accuracy, but serviceable life is shorter, durability is poor.If employing steel construction, then cost is higher.Another one shortcoming is photoelectric encoder (especially bearing circle have vibration) in rotary course, easy lossing signal, thus makes steering wheel angle numerical value occur mistake.
Existing scheme 3: steering wheel shaft is provided with pinion wheel, and pinion wheel is connected with gear wheel, mounting limit device on gear wheel.In addition, steering wheel shaft is installed multiple gear set, mounting spring on gear set, for steering wheel return just.Steering wheel shaft is installed an eccentric wheel again, for installation position displacement sensor thus direction of measurement dish corner.Be used for direction of measurement dish angle by eccentric method installation position displacement sensor, structure is comparatively complicated.In addition, in order to slow down time positive force of spring, have employed the method for multiple gear set, complex structure, cost is higher.
Existing scheme 4: the automobile driving simulator steering gear of a kind of force feedback and vibration, it comprises bearing circle, the first turning axle, the first gear, the second turning axle, the second gear, spacing swing handle, limited block, the first bar magnet, the second bar magnet, Hall angular transducer, wiring board, the 3rd gear, photoelectric encoder, the 3rd turning axle, the 4th gear, belt, the 5th gear, the 4th turning axle and motor.It can realize steering gear spacing, outer corner measurement, just returning and vibrating function, and signal error problem when bearing circle carries out Vibration Simulation can be revised well.Owing to adopting motor travel direction dish just to return, therefore have back positive dynamics size adjustable, Vibration Simulation, time good advantage of all even bearing circle feel of positive force can be carried out.Adopt photoelectric encoder and Hall angular transducer to carry out measurement of angle, outer corner measurement precision is higher simultaneously.But this steering gear structure is comparatively complicated, and cost is higher.
More above-mentioned four kinds of schemes, can find that scheme 4 can offer the best effect, but cost are higher.If machinery therefore can be adopted to return positive method, then can reduce costs greatly.
