Big synchronous pulley 9, steering drive axle 1, steering drive axle 2 11, universal joint 12, steering column 13, steering wheel 14.Its feature exists
In: the magnetic yoke 2 and Moving plate 3 are inserted in connecting shaft 4, and middle section has gasket to adjust its spacing, 1 axis of stepper motor and company
Spindle 4 is connected by flat key, and the small synchronous pulley 5 is fixed with Moving plate 3, and the end cap 6 is fixed on 4 shaft end of connecting shaft, described
Synchronous belt 7 and small synchronous pulley 5 and big synchronous pulley 9 cooperate, and 9 sets of the big synchronous pulley is on steering drive axle 1, institute
The position for stating big synchronous pulley 9 is locked by two axle sleeves 8, and the universal joint 12 is connect with the turning machine of steering system, and described turn
It is protruded under steering drive axle 2 11 in face to transmission shaft 1, the steering drive axle 2 11 and steering column 13 pass through universal
12 connection of section, the steering wheel 14 are connect with steering column 13.
A kind of above-mentioned unmanned steering mechanism of golf cart, magnetic yoke 2 is locked with Moving plate 3 when being powered, this time step
Into motor 1 torque can for delivery to wheel steering column 13, when magnetic yoke 2 powers off with the complete disconnection of Moving plate 3, at this time stepper motor
1 torque can not be transmitted to wheel steering column 13, and the position of big synchronous pulley 9 can be by adjusting two positioning shaft sleeves 8
Position adjusts up and down to realize, adjustment position regards specific installation space and determines.
Electric golf cart can control Vehicular turn under common driving mode with manual operation steering wheel, drive at nobody
It sails under mode, does not need manual operation steering wheel, vehicle can control steering column rotation under the drive of stepper motor, realize certainly
Turn to.Common driving mode and unmanned pattern switching have no need to change mechanical structure, the present invention is based on above-mentioned principle,
Working principle is:
Electric golf cart is powered to electromagnetic clutch first under unmanned mode, after electromagnetic clutch is powered,
Magnetic yoke and Moving plate are locked, stepper motor output torque by connecting shaft, Moving plate, small synchronous pulley, synchronous belt, big synchronous pulley and
Steering drive axle finally passes to steering column, realizes auto-steering；Electric golf cart under common driving mode, electromagnetism from
Clutch power-off, stepper motor power-off, at this point, magnetic yoke and the complete disconnection of Moving plate, manual operation wheel steering, not will drive at this time
Step motor shaft rotation, wheel steering are barely affected.
A kind of beneficial effect of the unmanned steering mechanism of golf cart of the present invention is: by without changing mechanical structure
Method switching the unmanned and common driving mode of electric golf cart under steering, facilitate program debugging and guarantee promptly
In the case of vehicle and personnel's physical safety, stepper motor torque is transmitted by synchronous belt under unmanned mode, compact-sized,
Transmission efficiency is high, and stability is high, and shelf life is long；Under common driving mode, manual operation wheel steering is hardly by shadow
It rings.Electromagnetic clutch is easy to control, and stability is high, and a whole set of unmanned steering mechanism is simple, can be applicable in and different electronic height
Golf ball vehicle.
