Utility model content
According to above the deficiencies in the prior art, a kind of side fork lift truck transmission device is provided, power transmission direction realizes 180 ° of rotations, and kinetic equation loss is little, meets speed change needs, facilitates fork truck space compact Layout, is convenient to maintenance, improves service life.
Side fork lift truck transmission device described in the utility model, its power intake comprises the engine flywheel, change speed gear box, the universal-joint that connect successively, its clutch end comprises the transmission shaft, the drive axle that connect successively, universal-joint and transmission shaft are connected by a horizontal chain-wheel box, chain-wheel box input end is provided with a minor sprocket, minor sprocket connects input terminal pad by input shaft, and input terminal pad is connected with universal-joint; Chain-wheel box mouth is provided with a hinge wheel, and hinge wheel connects output terminal pad by output shaft, and output terminal pad is connected with transmission shaft; Minor sprocket is connected by messenger chain with hinge wheel, and minor sprocket axis and hinge wheel axis be parallel to each other, and minor sprocket center is mutually vertical with its axis with the hinge wheel line of centres.
The power of driving engine through universal-joint by inputting terminal pad, input shaft passes to minor sprocket, minor sprocket passes to hinge wheel by messenger chain, hinge wheel through output shaft, output terminal pad by transmission of power to transmission shaft and drive axle, realize power output.The change of power transmission direction, to realize by the hinge wheel in chain-wheel box and minor sprocket, because minor sprocket axis and hinge wheel axis are parallel to each other, therefore, power transmission direction realizes 180 ° of rotations, and universal-joint and input shaft straight line transferring power are avoided the original mode that realizes transmission of power by universal-joint, greatly reduce kinetic equation loss, improved service life.The simultaneously flexible arrangement of driving engine, has facilitated the compact Layout in fork truck space, is convenient to maintenance.By changing the external diameter of hinge wheel and minor sprocket, can conveniently carry out speed change adjusting, meet speed change needs.
Described minor sprocket is identical with hinge wheel diameter, realizes the synchronous output of rotating speed.
Described minor sprocket diameter is less than hinge wheel diameter, and output speed is less than input speed, increases output torque, is suitable for the fork dress of large dead weight cargo.
Described minor sprocket diameter is greater than hinge wheel diameter, and output speed is greater than input speed, increases output torque, is suitable for the fork dress of little dead weight cargo.
Described messenger chain is silent chain, reliable operation, stable drive noiseless.
Driving engine is by engine flywheel output speed, first after change speed gear box speed change, be passed to input shaft by universal-joint, input terminal pad, input shaft drives minor sprocket to rotate, minor sprocket drives hinge wheel to rotate by messenger chain, hinge wheel drives output shaft rotation, and output shaft is exported power transmission to drive axle through output terminal pad, transmission shaft, thereby realizes 180 ° of rotations of power, by the diameter ratio of hinge wheel and minor sprocket is rationally set, realize speed change needs.
Compared with prior art, the beneficial effect the utlity model has is:
This side fork lift truck transmission device is realized 180 ° of rotations of power transmission direction by chain-wheel box, and kinetic equation loss is little, facilitates fork truck space compact Layout, is convenient to maintenance, improves service life; Realize speed change needs by hinge wheel and minor sprocket, flexible adjustment is convenient.
