Abstract

The utility is a hydraulic pressure buffering mechanical transmission framework of the shovel loader, relating to a transmission framework of shovel loader, in particular to an improved transmission framework, which consists of an engine, a lubricant pump, a reversing valve, a redirector, a hydraulic pressure motor, a transfer case and an oil box. The utility model is mainly characterized in that a flow divider is arranged between the lubricant pump and the redirector. The utility model takes out the digital to analog converter and the clutch and other supporting components from between the engine and the transfer case, provides a flow divider between the lubricate pump and the redirector, transform the hydraulic pressure to mechanical transmission, and endow the shovel loader with buffering when starting. The utility model greatly reduces wear and tear of mechanism and is convenient to maintain with a long service life.

Description

A kind of hydraulic cushion mechanical transmission structure of loader
Technical field:
The utility model relates to the driving mechanism of loader, is meant the improvement structure of its drive mechanism especially.
Background technique:
At present the loader driving mechanism all adopts two kinds: a kind ofly be made up of dry clutch and gearbox, transfer case etc.; Another kind drives device, gearbox, transfer case etc. by change and forms.First kind of dry clutch wearing piece rapid wear, working life is short, the operation easier height, mechanical loss is big; Second kind of change driven device and cost an arm and a leg, complex structure, and maintenance is inconvenient.
Summary of the invention:
The purpose of this utility model be to overcome above deficiency and provide a kind of simple in structure, cost is low, reduces the hydraulic cushion mechanical transmission structure of mechanical loss.
The utility model is achieved by the following technical solution: a kind of hydraulic cushion mechanical transmission structure of loader, comprise motor, oil pump, selector valve, commutator, oil hydraulic motor, transfer case, fuel tank, its major technique feature is to be provided with diverter valve between oil pump and selector valve;
By motor transmission oil pump, oil pump divides turnover oily two holes, oil inlet hole oil pipe fuel tank, oil outlet connects diverter valve with high-pressure oil pipe, and the oil inlet pipe of diverter valve is connected with oil pump, and an oil outlet tube of diverter valve connects selector valve, another oil outlet tube connects commutator, two oil outlets of selector valve connect oil hydraulic motor with high-pressure oil pipe, and another oil outlet connects fuel tank with oil pipe, and oil hydraulic motor connects transfer case with the elasticity connecting shaft.
The utility model is provided with diverter valve having removed related accessory such as torque converter and clutch between original motor and the transfer case between oil pump and selector valve, change into mechanical transmission by hydraulic pressure, makes loader play buffer function when starting.The utility model greatly reduces mechanical loss, and is easy to maintenance, long service life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
As shown in Figure 1, connect oil pump 2 by motor 1, oil inlet hole of oil pump connects fuel tank 8 with oil pipe, another oil outlet connects diverter valve 3 with high-pressure oil pipe, two oil outlets of diverter valve connect commutator 5 and selector valve 4 with high-pressure oil pipe respectively, and selector valve has three oil outlets, and an one oil outlet connects fuel tank with oil pipe, two oil outlets connect liquid motor 6 with high-pressure oil pipe in addition, and oil hydraulic motor is fixedlyed connected with transfer case 7 usefulness screws.
Its working principle is that the discharge capacity of oil pump changes along with the rotating speed of motor, and the discharge capacity of oil pump is very little when having started low-speed running, and the oil mass of at this moment supplying with diverter valve can only be limited to the oil mass of commutator.When loader is started working the commutation valve rod moved into and advance or when retreating desired location, slowly step on the throttle, motor quickens, oil pump capacity strengthens thereupon, is shunted to the oil hydraulic motor rotation by diverter valve, and loader is slowly started to walk then, reduced mechanical wear, and when starting stationarity good.
