Description
Technical field
The present invention relates to the construction machinery and equipment turbine transformer, particularly a kind of tor-con cooling and lubricating system and use the loader of this system.
Background technology
Circulation cooling lubricating system in existing loader generally adopts with turbine transformer.See also Fig. 1 and Fig. 2, wherein, Fig. 1 is the schematic diagram of this system, and Fig. 2 is the integral structure scheme drawing of this tor-con.
In the working process, speed-variable pump 30 turns round under the drive of driving engine, gets cutting oil through fil 20 from fuel tank 10 pumps.After pressure oil liquid enters change speed gear box by pass valve 40, a part flows out in the change speed gear box clutch system E for its use, after the spool that another part pressure oil acts on change speed gear box by pass valve 40 produce to move, pipeline 101 (see figure 2)s that one curb the tor-con enclosure interior enter fuel feed hole 102 are set on the wheel stand, thereby enter three element system (pump impeller, guide wheel, turbine), this part fluid when three element is rotated under action of centrifugal force, splash to the cover wheel along the slit between three element inner, to antifriction-bearing box, piece surfaces such as turbine seat carry out cooling and lubricating, the oil that flows out from three element system 60 flows out along oil outlet 103 (see figure 2)s that wheel stand is provided with, oil duct on housing 104 inflow radiators 70 cool off then, finally enter into the F of loading machine gearbox system; The spool pressure spring 501 pressure promotion tor-con overflow spool 502 that another road then overcomes tor-con by pass valve 50 enters into auxiliary gear box 80 (see figure 2)s, parts such as auxiliary gear box in-to-in speed-variable pump, working barrel, steering pump driven wheel, bearing are carried out cooling and lubricating, this cooling and lubricating mode is for drenching oil, and the oil behind the pouring oil is by draining hole oil sump tank.
Above-mentioned analysis as can be known, loader tor-con cooling and lubricating mode adopts to be offered oilhole and sets up the passage that the three element system is carried out cooling and lubricating on wheel stand inside, in the working process, cutting oil is in the part internal flow, utilize the speed of oil stream that three element (pump impeller, guide wheel, turbine) and attached parts are carried out cooling and lubricating, utilize liquid between the three element blade surface, to apply the purpose that moment of momentum reaches transmission of power simultaneously.For auxiliary gear box, it adopts in a high position and sets out oilhole to parts such as the gear cooling and lubricating that splashes.Aforementioned interior circulation cooling lubricating system is provided with oil hole and carries out cooling and lubricating on wheel stand, realized the high-mobility, multipurpose, wheeled vehicle of single part, has stronger cost performance.

Under the higher work condition environment of temperature (tor-con oil outlet oil temperature above 120 ℃), when loader is in long mode of operation, need startup outer circulation forced cooling lubricating system.The temperature sensor 14 that is positioned at the liquid outlet of three element system 6 sends an electrical signal to instrument carrier panel annunciator 16 according to the oily temperature that detects the tor-con oil outlet, loader drive person can observe the annunciator control key 123 that oily temperature display instrument 15 is made judgement and start-up control panel according to alerting signal, and annunciator 16 cuts out; Press the lubricated button 121 of three element system forced cooling simultaneously, switch to three element system surfaces refrigerating mode, like this, button sends electric signal and gives 3-position-3-way solenoid directional control valve 11, solenoid directional control valve gets the electric position, a left side that switches to, and fluid enters three element system 6 by the inside oil duct of diverter 13.Under this state, respectively parts such as 61 outside faces of the pump impeller in the three element system 6, cover wheel 62 outside faces are forced the oil spout cooling by fueling injection equipment, realize the refrigerating function of three element system outside face through tor-con outer loop cutting oil; Thereby by inside and outside two circulating systems the three element system of tor-con is carried out synchronous comprehensive cooling and lubricating, provide the failure-free guarantee under the worst hot case environment for tor-con can work long hours.
When the oil temperature continued to raise, chaufeur was pressed the lubricated button 122 of torque converter assemblage forced cooling, starts the comprehensive cooling and lubricating pattern of tor-con; The lubricated button 122 of torque converter assemblage forced cooling sends electric signal and gives threeway three-position electromagnetic change-over valve 11, solenoid directional control valve gets the electric right position that switches to, cutting oil enters three element system and auxiliary gear box system simultaneously by the inside oil duct of diverter 13, lubricated to the effusion cooling of fixing a point of all parts in three element and the auxiliary gear box system, all cutting oils enter into heat radiator assembly by combiner valve 23 and carry out the thermal exchange cooling, enter into transmission system F at last.
Special version be that the tor-con circulation cooling lubricating system that this programme provides is applicable to the tor-con cooling and lubricating of Other Engineering machinery; Simultaneously, this scheme is not only applicable to new product designs, also is suitable for the transformation and upgrade of delivered vehicle type, and the change position is less, and operability is stronger.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
