Description
The utility model relates to bicycle and man, specifically a kind of before driving tray three-wheel vehicle.
At present tricycle mainly is made up of a front-wheel, two trailing wheels and vehicle frame, is finished turning to by front-wheel, back-wheel drive, tricycle car body greatly, from great, complex structure.Before turn to, the mode of rear drive makes people by bike the time, approaches erectility, the air resistance when having increased by bike, thus cause difficulty by bike, simultaneously, make the people be difficult to give play to the strength bigger than deadweight, limited the ability of people's leg acting.
The purpose of this utility model is to provide a kind of before driving tray three-wheel vehicle of being finished driving by front-wheel.
The technical solution of the utility model is: a kind of before driving tray three-wheel vehicle, mainly to form by vehicle frame, tray, front-wheel and two trailing wheels and vehicle seat, and front-wheel is installed in the inside of vehicle frame, and two trailing wheels are installed in the and arranged on left and right sides of tray.Vehicle frame is hinged with tray with sleeve mutually by rotating shaft, it is characterized in that: the leading section at vehicle frame also is provided with pedal, and pedal links to each other with front-wheel with flywheel by sprocket wheel, chain, is provided with in the front portion of tray and turns to push rod.
The utility model is owing to be provided with the before driving function, and the windward side of human body is little, and the air resistance when having effectively reduced by bike is provided with the vehicle seat of backrest, makes people's leg can give play to bigger strength, and load is increased.The utility model is simple in structure, speed is fast, in light weight, load carrying ability is big, has the Energy and comfort of riding, tireless effect.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is plan structure figure of the present utility model.
Accompanying drawing number: 1, pedal 2, front-wheel 3, flywheel 4, vehicle frame 5, connecting rod 6, brake guide rod 7, trailing wheel 8, tray 9, sprocket wheel 10, chain 11, turn to push rod 12, rotating shaft 13, sleeve 14, vehicle seat 15, brake lever 16, brake band
