Abstract
The invention relates to a steering device for a children toy car steering wheel, which is suitable for being used as steering driving devices of steering wheels for children electric cars, children toy cars and the like. The device comprises a steering wheel, a steering wheel shaft, a gear wheel, a circular arc gear rack plate and a wheel connecting rod. One side of the circular arc gear rack plate is provided with a circular arc gear rack. A circular arc groove is arranged on the circular arc gear rack plate. The steering wheel shaft is arranged under the steering wheel, and the lower end thereof is provided with the gear wheel. The gear wheel is engaged with the circular arc gear rack. The lower end of the steering wheel shaft is arranged in the circular arc groove. The circular arc gear rack plate is fixed on the wheel connecting rod. The wheel connecting rod is movably connected with a wheel swinging arm. The wheel swinging arm is connected with the wheel axles. The circular arc groove has the same centre with the circular arc gear rack. The invention adopts the gear wheel and the circular arc gear rack, drives the wheel to steer by the wheel connecting rod, lightens the applied force for steering the steering wheel, increases the rotation angle and range of the steering wheel, decreases the swinging speed of the wheel during steering adjustment and enhances the driving stability of the car.
Description
Technical field
What the present invention relates to is a kind of children's electric motor vehicle wheel steering device, is applicable to that children's electronlmobil, children toy car etc. make the wheel steering driving device.
Background technology
Children toy car, children's electronlmobil wheel steering device adopt steering wheel shaft bottom hook to drive wheel steering by the wheel connecting rod at present, wheel steering need spend bigger strength to require great effort very much for young children, be not easy manual reverse of direction, bearing circle rotational angle setting range is little, it is too fast to turn to adjusting that wobbling of wheels is turned to, and causes vehicle ' dangerous.
Summary of the invention
The present invention seeks to provides a kind of steering device for children toy car steering wheel at above-mentioned weak point, adopt gear, arc rack, drive wheel steering by the wheel connecting rod, alleviating wheel steering firmly very spends, augment direction dish rotational angle and scope, wobbling of wheels speed is slow when turning to adjusting, has improved vehicle run stability.
Steering device for children toy car steering wheel takes following scheme to realize: steering device for children toy car steering wheel comprises bearing circle, steering wheel shaft, gear, circle-arc tooth batten and wheel connecting rod.Circle-arc tooth batten one side is provided with arc rack, and the circle-arc tooth batten is provided with arc groove, and steering wheel shaft is equipped with in the bearing circle bottom, and gear is equipped with in the steering wheel shaft lower end, gear and arc rack engagement, and the steering wheel shaft bottom is installed in the arc groove; The circle-arc tooth batten is fixed on the wheel connecting rod.
Described wheel connecting rod and wheel swing arm flexibly connect, and the wheel swing arm links to each other with axletree.
Described arc groove and arc rack are the same center of circle.
Owing to form arc track when the wheel swing arm is rotated, therefore rack-plate of the present invention is provided with the arc-shaped rack and the arc groove of associated circular arc, track was consistent when the track in the time of can making the swing of arc rack plate rotated with the wheel swing arm, was meshed with arc rack to reach gear.
When children toy car turned to, steering wheel rotation rotated along arc rack by being fixed on steering wheel shaft lower end gear gently, driving the circle-arc tooth batten swings, arc rack strip motor-car wheel connecting rod by wheel swing arm geared wheel left-right rotation, realizes that children toy car turns to again.
Steering device for children toy car steering wheel is reasonable in design, compact conformation, because adopt the gear arc rack to drive wheel steering by the wheel connecting rod, required steering effort is little, is applicable to that children turn to, wheel steering angle and scope are big, turn to flexibly, noiselessness is owing to adopt gear, arc rack transmission, wobbling of wheels speed is slow when turning to adjusting, can improve children toy car and turn to riding stability and safety.
Description of drawings
The invention will be further described below with reference to accompanying drawing.
Fig. 1 is the steering device for children toy car steering wheel scheme drawing.
The specific embodiment
With reference to accompanying drawing 1, steering device for children toy car steering wheel comprises bearing circle 1, steering wheel shaft 2, gear 4, circle-arc tooth batten 3 and wheel connecting rod 7.Circle-arc tooth batten 3 one sides are provided with arc rack 5, circle-arc tooth batten 3 is provided with arc groove 6, and steering wheel shaft 2 is equipped with in bearing circle 1 bottom, and steering wheel shaft 2 lower ends are fixed with gear 4, gear 4 and arc rack 5 engagements, steering wheel shaft 2 bottoms are installed in the arc groove 6; Circle-arc tooth batten 3 is fixed on the wheel connecting rod 7, and wheel connecting rod 7 flexibly connects with wheel swing arm 8, and wheel swing arm 8 links to each other with axletree 9.Wheel 10 is contained on the axletree 9.
Described arc groove 6 is the same center of circle with arc rack 5.
Described steering wheel shaft 2 bottoms are positioned in the arc groove 6 by packing ring, shaft lock, or are positioned in the arc groove 6 by packing ring, nut.
