Abstract
The utility model discloses a power transmission mechanism for motorcycles. An oil pump 2 is directly driven by a motor 1; the oil pump 2 is connected with a control valve; the high pressure outlet 6 of the control valve make high pressure oil be transferred on an oil motor 8 of a rear wheel through a high pressure soft pipe 7. Then a motor 8 is driven to rotate. Thereby, the rear wheel is driven to travel forwards.
Description
The mechanism of the transmission of power that the utility model relates to motor cycle engine to the trailing wheel.
As everyone knows, the power of existing motor cycle engine is by speed-change gear output, is delivered on the motor cycle rear wheel by chain, transmission shaft or belt again, drives motor bike to overtake.Each part requirement of speed-change gear has higher precision, and its manufacturing cost is higher in other words.Motor bike when operation and since trailing wheel have one after the rocking arm bearing pin be the capable motion of arc in the center of circle, make chain, belt when transfers power, also will bear a pulling force or a pressure radially, this pulling force or pressure are having a strong impact on life-span of chain or belt.If adopt shaft drive, two-wheeled motorcycle can be subjected to the restriction in space.
The utility model is that a kind of gearless transmission system will be provided, and transmitting ratio is than pulsation-free motor bike Poewr transmission mechanism.
The utility model is achieved in that an end of engine crankshaft connects by an oil pump, oil pump is oil suction from fuel tank, the outlet of oil pump is connected with control cock above being installed in fuel tank, the high-pressure outlet of control cock is connected with the oil inlet of oil motor on being connected trailing wheel, and the oil outlet of oil motor is connected in the fuel tank by oil return pipe again.Wherein the backguy and the engine throttle backguy of the valve rod of dominant discharge outside link together by a three-way pipe, are connected on the handgrip.
The utility model has substituted original speed-change gear by an oil pump and control cock, original belt and belt pulley, chain and sprocket wheel or transmission shaft and bevel type gear have been substituted by a high pressure hose and oil motor, so it is simple in structure, manufacturing cost is lower, and has improved the acceleration capability of motor bike.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is the scheme drawing of an embodiment of the present utility model.
The Poewr transmission mechanism of motor cycle engine shown in Figure 1, driving engine 1 directly links to each other with oil pump 2, be connected by the oil outlet 3 of pump oil inlet 5 through the top control cock of high pressure hoses and fuel tank 4, the oil inlet 9 of the oil motor 8 on the oil outlet 6 of control cock passes through high pressure hoses 7 and is installed in trailing wheel is connected, the oil return liquid of oil motor flows into backflash 11 by three on the motor case fuel return holes that increase gradually 10, flows back to fuel tank by an oil return pipe 12 again.The motor bike operation is flowed back to fuel tank to the fluid that the plain bearing place at oil motor produces through two low pressure pipes 13.
