At present, fluid torque converter is widely used in the transmission system of bulldozer as the basic pattern of hydraudynamic drive.Its major function is the variation that adapts to external resistance automatically, makes vehicle can infinitely change the torque and the rotating speed of its output shaft within the specific limits.The torque-converters control valve then is the core of fluid torque converter, is used to regulate the import oil pressure of torque-converters.The torque-converters control valve of existing bulldozer below 420 horsepowers mainly is made up of pressure regulator valve etc., and main relief valve wherein and torque converter valve etc. belong to discrete component, and independent separately the installation by the pipeline connection, exists the shortcoming that the pressure loss is big, structure function is single.
Summary of the invention
The purpose of this invention is to provide a kind of torque converter valve that cooperates realization hydraudynamic drive and the mutual conversion function of mechanical transmission with the torque converter locking oil cylinder, and the main relief valve of integrated transmission system.
The technical solution that the present invention adopts is: the valve of former function singleness is integrated into a multi-functional torque converter valve, is made up of torque-converters relief valve, main relief valve, clutch of stator modulation valve, lockup clutch modulation valve and locking selector valve etc.
The torque-converters relief valve mainly is made up of guiding valve I, spool I, spring I, spool II, spring II etc., and effect is an interface pressure of regulating torque-converters, in case it is subjected to the influence of abnormal pressure;
Main relief valve is made up of spring III, guiding valve II, spool III, spring IV, spool IV etc., effect be regulate speed change, turn to, the pressure of braking system;
The clutch of stator modulation valve is formed the structure of a hydrovalve by spool V, spring V, guiding valve III, spool VI, spring VI, spool VII etc., and effect is to adjust the pressure that exports clutch of stator to;
The effect of lockup clutch modulation valve is to adjust the pressure that exports lockup clutch to, and structural principle is similar to the clutch of stator modulation valve, and just the pressure of output is different with clutch of stator, and parts such as pressure spring have change slightly.
More than four kinds of valves install concentratedly on valve body III by the casting valve body, the sealing of O RunddichtringO is adopted at the valve two ends.
The locking selector is made up of pilot valve and main valve, belongs to the electrically controlled and hydraulically valve.It is positioned at the front end of clutch of stator and lockup clutch in oil-way system, effect is that optionally pilot pressure oil exports clutch of stator or lockup clutch to.The major part that main valve is formed has: plunger, guiding valve IV, spring VII, valve body I etc., and pilot valve mainly is made up of plugged electric magnet valve, valve body II etc., is installed on the main valve body I by screw, and the sealing of O type circle is adopted in sealing.
When torque converter valve was installed, the locking selector valve that will be installed in the valve body III top with bolt was fixed on the torque-converters with valve body III.Adopt the sealing gasket I sealing between locking selector valve and the valve body III, valve body III and torque-converters mounting plane adopt sealing gasket I I sealing.
In the hydraulic schematic diagram, pressure oil enters from P, and one the tunnel exports torque-converters to through main relief valve, as the working oil of torque-converters, is adjusted the pressure of torque-converters simultaneously by the torque-converters relief valve; Another road exports pressure oil to clutch of stator through the locking selector valve, and after the pilot valve commutation, the locking selector valve exports pressure oil to lockup clutch.
The invention has the beneficial effects as follows, the regulator, torque-converters relief valve, clutch of stator modulation valve, lockup clutch modulation valve of gathering speed change, braking in a turn system in the bulldozer transmission system are in one, the pipeline that reduces between each discrete component connects, and the pressure loss is greatly reduced; And increased the function of control torque-converters with fluid power and/or machinery type outputting power.Realize the concentrated adjustment and the control of speed change steering system, torque-converters, lockup clutch, clutch of stator.
