Description
Technical field: the utility model relates to three wheeled motor car, relates in particular to a kind of heavy burden formula three wheeled motor car.
Background technology: the three wheeled motor car of prior art, it mainly is design goal with the road transport, the design speed per hour is higher, especially should be three wheeled motor car for the agricultural service, because during design is upward used with reality, be mainly used in road transport, rotating speed height and moment of torsion is low, and do not meet the primary demand of agricultural operation.
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of heavy burden formula three wheeled motor car is provided, and to reduce the output speed of three-wheel vehicle, improves the design philosophy of moment of torsion, makes the rotating speed of three-wheel vehicle and the primary demand that pulling force meets agricultural operation.
Summary of the invention: a kind of heavy burden formula three wheeled motor car described in the utility model, including front-wheel, handlebar, vehicle frame, trailing wheel, engine, belt pulley, miniature gears, big gear wheel and power wheel forms, the three-wheel vehicle of said front-wheel, handlebar, vehicle frame and trailing wheel and prior art is basic identical, front-wheel is a track adjusting wheel of the present utility model, be arranged on the front end of vehicle frame, handlebar is arranged on the top of front-wheel, is used to control turning to of front-wheel.Vehicle frame is a body supports part of the present utility model, and the rear end of vehicle frame is provided with trailing wheel, the strut member that front-wheel and trailing wheel also move on the ground as the vehicle frame kiss the earth jointly.Form change speed gear box of the present utility model by axle, miniature gears, big gear wheel and power wheel, vehicle frame between front-wheel and the trailing wheel is provided with engine, as propulsion source of the present utility model, the output wheel of engine is a belt pulley, the wheel that change speed gear box is accepted power also is a belt pulley, be the needs in order to slow down, the power-take-off pulley of engine is less than the belt pulley on the change speed gear box.The engine of heavy burden formula three wheeled motor car described in the utility model is arranged between front-wheel and the trailing wheel slightly near on the vehicle frame of front-wheel.Because gearbox pulley is greater than the power-take-off pulley on the engine, this has just carried out first order deceleration.A miniature gears in the coaxial drive change speed gear box of gearbox pulley, miniature gears again with two on big gear wheel engagement, the coaxial again drive miniature gears of big gear wheel on two, the miniature gears on two again with three on the big gear wheel engagement, can also be provided with four or five again.End at last gear wheel shaft of change speed gear box is provided with power wheel, the coaxial drive power wheel of change speed gear box output wheel, and power wheel drives trailing wheel with the form of gear mesh, drives heavy burden formula three wheeled motor car motion described in the utility model.Heavy burden formula three wheeled motor car described in the utility model can be used for road transport, also can be used for the farmland and plough and to rake the soil level and other farm work operation.When carrying out farmland operation, trailing wheel can be replaced by the steel ratchet wheel to increase mobility.
Use heavy burden formula three wheeled motor car technology described in the utility model, both can be used for the road transport operation, also can be used for farmland farm work operation, the three-wheel vehicle integral structure is simple, easy to use, over-the-road expense is low, is adapted at using under the multiple topographic condition, can be used as the ideal equipment that substitutes the manpower work.
Description of drawings: accompanying drawing is the structural representation of a kind of formula three wheeled motor car that bears a heavy burden described in the utility model.1-front-wheel 2-handlebar 3-vehicle frame 4-trailing wheel 5-engine 6-belt pulley 7-miniature gears 8-big gear wheel 9-power wheel
The specific embodiment: referring now to accompanying drawing, be described as follows in conjunction with the embodiments: a kind of heavy burden formula three wheeled motor car described in the utility model, include front-wheel 1, handlebar 2, vehicle frame 3, trailing wheel 4, engine 5, belt pulley 6, miniature gears 7, big gear wheel 8 and power wheel 9 are formed, said front-wheel 1, handlebar 2, vehicle frame 3 and trailing wheel 4 are basic identical with the three-wheel vehicle of prior art, by miniature gears 7, big gear wheel 8 and power wheel 9 are formed change speed gear box of the present utility model, vehicle frame is provided with engine 5, as propulsion source of the present utility model, the output wheel of engine 5 is belt pulleys 6, the wheel that change speed gear box is accepted power also is a belt pulley, be the needs in order to slow down, the output wheel of engine is less than the belt pulley on the change speed gear box.Said change speed gear box is exactly a drop-gear box of the present utility model, is provided with axle in the drop-gear box, and axle is provided with miniature gears 7 and big gear wheel 8, should be provided with one and two at least, according to the needs of reduction ratio, can also be provided with three, four, even more axle.The engine 5 of heavy burden formula three wheeled motor car described in the utility model is arranged between front-wheel 1 and the trailing wheel 4 slightly near on the vehicle frame of front-wheel 1.Because gearbox pulley is greater than the power-take-off pulley on the engine 6, this has just carried out first order deceleration.A miniature gears 7 in the coaxial drive change speed gear box of gearbox pulley, miniature gears 7 again with two on big gear wheel 8 engagement, coaxial again another miniature gears of drive of big gear wheel 8 on two, the miniature gears on two again with three on the big gear wheel engagement, can also be provided with four or five again.End at last gear wheel shaft of change speed gear box is provided with power wheel 9, the coaxial drive power wheel 9 of change speed gear box output wheel, and power wheel 9 is connected with trailing wheel 4 with the form of gear mesh, drives heavy burden formula three wheeled motor car motion described in the utility model.Heavy burden formula three wheeled motor car described in the utility model can be used for road transport, also can be used for the farmland and plough and to rake the soil level and other farm work operation.When carrying out farmland operation, trailing wheel can be replaced by the steel ratchet wheel to increase mobility.Use heavy burden formula three wheeled motor car technology described in the utility model, both can be used for the road transport operation, also can be used for farmland farm work operation, the three-wheel vehicle integral structure is simple, easy to use, over-the-road expense is low, is adapted at using under the multiple topographic condition, can be used as the ideal equipment that substitutes the manpower work.Heavy burden formula three wheeled motor car described in the utility model also can be arranged to four-wheeled, just has under the situation of two wheels in track adjusting wheel, guarantee turning to synchronously of two track adjusting wheels with interlinked mechanism.The diameter of said power wheel 9 can amplify also and can dwindle, according to needed speed of a motor vehicle adjustment.
