Abstract
The utility model provides a power and steering device of four-wheeled prams. Accumulators are used for the power by four-wheeled prams in markets, and three-wheeled and two-wheeled prams are also offered by the market. The prams which are offered by the market has the disadvantages that the structure is complicated, the maintenance is inconvenient, and the prams can not drive on ordinary road surfaces; the three-wheeled and the two-wheeled prams has the disadvantages that the stability is bad, the three-wheeled and the two-wheeled prams are difficult for preschool children to learn, the turning radius is small, the backing can not be carried out by the three-wheeled and the two-wheeled prams, and dangers are easily happened. The utility model has the advantages that the structure is simple, the utility model is not easily damaged, the turning radius is large, the utility model can be driven in a front and a back directions, the utility model is safe, and the utility model can provides the power and a steering device for the prams with various shapes.
Description
The utility model relates to a kind of power and the steering hardware of four-wheel perambulator.
The four-wheel perambulator that provides in the market generally is that storage battery is that power and foot-operated three-wheel, two are taken turns perambulator, and the former structure more complicated is easy-maintaining not, general road can not be travelled, latter's less stable, and the preprimary child is difficult for grasping, also can not move backward poor stability because turn radius is less.
For address this problem just need provide a kind of for 2-6 year children required simple in structure, not fragile, turn radius is bigger, can before and after travel, be convenient to grasp, safe and reliable, be convenient to the power and the steering hardware of the diversified four-wheel perambulator of profile.
The purpose of this utility model is that a kind of power and steering hardware for various car conour perambulator adapteds will be provided.
The purpose of this utility model is achieved in that engine installation is to be fixed on the hyperbolic wheel shaft protuberance position by hyperbolic wheel shaft 14, pedal 18, and two preceding tight pulleys 16 are separately fixed at end, hyperbolic wheel shaft 14 two ends.Tight pulley 16 rolls forward and has realized car to overtake before 14 works done two of hyperbolic axle when both feet alternately step pedal 18, during reversing, can finish as long as both feet step pedal 18 by opposite sense; Steering hardware is to insert sleeve pipe 11, end, core pipe 12 upper ends and bearing circle 13 centres by bearing circle 13, sleeve pipe 11 (being separately fixed on the top A-frame 6, on the bottom A-frame 10) core pipe 12 to be connected and fixed.End, core pipe 12 lower ends becomes 90 ° to be connected and fixed with lever 8 centres, end, lever 8 two ends links (connection), the other end and two universal wheel shafts, 26 medial extremity ends (the bridge wheel shaft 15 vertical position control other ends and two universal wheel shafts, 26 medial extremity ends (bridge wheel shaft 15 vertical position control rope holes 23) hinge joints (connection) with two control stalks 9 (control rope 20) end end respectively.When both hands produce swings with bearing circle lever 8 when anticlockwise direction or clockwise direction rotate, make control stalk 9 (control rope 20) do to support that roping is moving promptly drives cardan wheel 26 (bridge wheel shaft 15) and seesaw by direction shown in accompanying drawing 5,6 arrows, promptly realized turning to of car.
