Abstract
The utility model discloses a motorcycle hydraulic drive system which is characterized in that a motorcycle engine drives a shaft of a plunger type hydraulic pump to rotate, and pressurized hydraulic oil flows into a plunger type hydraulic motor and pushes the plunger type hydraulic motor to rotate through a speed regulating valve; a shaft of the rotary plunger type hydraulic motor is connected with a rear wheel of a motorcycle and drives the motorcycle to move forward, and reflux oil of the speed regulating valve and the plunger type hydraulic motor is connected with a hydraulic oil tank through an oil pipe, wherein hydraulic oil in the hydraulic oil tank is connected with the plunger type hydraulic pump through a cleaner and a switch. The motorcycle hydraulic drive system of the utility model replaces a universal motorcycle drive system, ensures that the engine rotary speed of 3500 turns per minute in the starting of a motorcycle is reduced to 1200 turns per minute and causes a motorcycle to reduce oil consumption to 1.2-1.5 kg per hundred kilometer. After changed into a hydraulic drive mode, a motorcycle runs stably, noise is greatly reduced and the exhaust of tail gas is reduced following the reduced engine rotary speed. The hydraulic drive system of the utility model can also be used on motor vehicles, farm vehicles and small cars.
Description
Technical field: the utility model relates to the driving system of motor bike, specifically about the power hydraulic system of motor bike.
Background technology: existing motor bike will pass through change speed gear box from the power of driving engine output, chain or belt are delivered on the motor cycle rear wheel and drive motor bike and move ahead, the friction force of each parts has caused kinetic equation loss in the power transmission process, the increase of simultaneous noise changes hydrostatic drive into and just can overcome above-mentioned shortcoming.In view of large-scale engineering truck, some has adopted power hydraulic system, the contriver who has attempts power hydraulic system is transplanted to motor bike, on the vehicle such as bicycle, Chinese patent CN2405858Y, CN2400357Y is exactly tangible example, what use in the last item patent is vane motor, what use in the patent in back is the turbo type HM Hydraulic Motor, the vane motor rotating speed can not be too high, generally all under the situation that per minute 200 changes, work, and contamination resistance is poor, cleanliness level to oil is had relatively high expectations, and the turbo type HM Hydraulic Motor could do work when having only rotating speed to reach a certain height, so these two kinds of HM Hydraulic Motor all can not be used for the power hydraulic system on the bigger light-duty vehicle of velocity variations.
Summary of the invention: the purpose of this utility model is to adopt plunger pump to constitute the power hydraulic system of motor bike as Hydraulic Pump and HM Hydraulic Motor.The technical solution of the utility model is achieved in that motor cycle engine drives the axle rotation of pluger type hydraulic pump, hydraulic oil after the pressurization enters plunger hydraulic motor and promotes its rotation by governor valve, the axle of the plunger hydraulic motor of rotation connects the driving motor bike and moves ahead with the trailing wheel of motor bike, Hydraulic Pump and HM Hydraulic Motor and governor valve all have another oil pipe and hydraulic reservoir to link, guarantee circulating of hydraulic oil, also in the oil circuit that hydraulic reservoir and Hydraulic Pump link, be provided with fil and switch.
Here said its structure of plunger hydraulic motor is the same with pluger type hydraulic pump, and pluger type hydraulic pump is with the hydraulic oil pressurization, the rotation of actuation plunger formula HM Hydraulic Motor, and the plunger hydraulic motor outputting power drives motor bike and moves ahead.
Description of drawings: Fig. 1, each parts of motorcycle hydraulic driving system and oil circuit constitute scheme drawing; Fig. 2, pluger type hydraulic pump (plunger hydraulic motor) axial arrangement section-drawing; Fig. 3, governor valve axial arrangement section-drawing.
Among the figure: the extrusion chamber 19-spring 20-oil inlet and outlet 21-flow speed control valve connecting rod 22-spring 23-piston 24-shell 25-backflow hydraulic fluid port 26-pressure oil import 27-pressure oil outlet on the suction chamber 18-oil distribution casing on the axle 10-bearing 11-swash plate 12-return plate 13-plunger 14-shell 15-cylinder body 16-oil distribution casing 17-oil distribution casing of 1-hydraulic oil container 2-pluger type hydraulic pump 3-motorcycle engine 4-flow speed control valve 5-plunger hydraulic motor 6-oil pipe 7-switch 8-cleaner 9-hydraulic pump
The specific embodiment: as shown in the figure, a kind of motorcycle hydraulic driving system, it is characterized in that: motor cycle engine (3) drives the axle rotation of pluger type hydraulic pump (2), hydraulic oil after the pressurization enters plunger hydraulic motor (5) and promotes its rotation by governor valve (4), the axle of the plunger hydraulic motor (5) of rotation connects the driving motor bike and moves ahead with the trailing wheel of motor bike, the withdrawing oil of governor valve (4) and plunger hydraulic motor (5) links to each other with hydraulic reservoir (1) by oil pipe (6), and the hydraulic oil in the hydraulic reservoir (1) is connected with pluger type hydraulic pump (2) with switch (7) by fil (8).The principle of work of governor valve (4) as shown in Figure 3, go up stay cord of connection at governor valve connecting rod (21), be connected to simultaneously on the right handle of motor bike with the throttle control line of motor bike, when moving on the piston of governor valve (23), pressure oil import (26) and pressure oil outlet (27) form path, part or all of opposite then pressure oil refluxes from backflow hydraulic fluid port (25), reaches the rotating speed of modulated pressure motor (5) like this by the flow of control presssure oil.The principle of work of pluger type hydraulic pump or plunger hydraulic motor as shown in Figure 2.
Motorcycle hydraulic driving system of the present utility model substitutes general-duty motor bike driving system because of having saved change speed gear box, engine speed in the time of can making the motor bike starting is reduced to 1200 rev/mins for 3500 rev/mins, make hundred kilometers oil consumptions of motor bike be reduced to the 1.2-1.5 kilogram, energy-saving effect is very remarkable, after motor bike changed hydrostatic drive into, because of fluid has damping capaicty, motor bike operated steadily, noise greatly reduces, and has reduced exhaust emissions with the reduction of engine speed.Because power hydraulic system has self-lubricating function, and fault rate is low, power hydraulic system of the present utility model also can be used for battery-driven car, farm vehicle and miniature car in addition.
