Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
The utility model discloses a kind of transmission oil cavity configuration, mainly solve existing speed changer and be difficult in pressure lubrication, force cooling, force to cool off the problem of switching between these mode of operations of again pressure lubrication first, a kind of device that can realize switching fast oil circuit is provided.The utility model can be realized speed changer according to different operating modes, selects different mode of operations.
Concrete technical solution of the present utility model is as follows:
Dividing plate 8 between above-mentioned upper oil cavitie and the lower oil cavitie is processed with a through hole 7 thereon, and therefore two oil pockets can be connected as a single entity, oil connection can be passed through hole 7 again, stretch into upper oil cavitie 9, the pressure oil in the upper oil cavitie 9 is directly led outside the speed changer, thereby with upper lower oil cavitie separately.
Two tapped holes of above-mentioned speed changer oil pocket bottom, both plug screw can be installed, and also oil connection can be installed, and one of them tapped hole is coaxial with the through hole 7 on the aforementioned barriers, long oil pipe joint 11 passes first the tapped hole of bottom, pierces in the through hole 7 of dividing plate 8 again.
Above-mentioned oil connection is hollow-core construction, and an end of long oil pipe joint 11 is processed with the shaft shoulder, and the shaft shoulder and 8 on upper lower oil cavitie dividing plate are equipped with the second seal washer 12, and upper lower oil cavitie is thoroughly separated.
Described oil pump case 2 usefulness fastening pieces 3 are installed on the case of transmission 1.Case of transmission 1, oil pump case 2 and dividing plate 8 form two oil pockets together, i.e. lower oil cavitie 6 and upper oil cavitie 9; Dividing plate 8 by upper lower oil cavitie between these two oil pockets separates them, but keeps simultaneously the through hole 7 of the upper lower oil cavitie of a circle.Upper oil cavitie 9 communicates with the pressure oil cavity of transmission oil pump, and the pressure lubrication passage A in lower oil cavitie 6 and the speed changer is communicated with.
When fluid did not need outer loop, two oil circuit switching ports of described lower oil cavitie bottom (being two tapped holes of oil pocket bottom) sealed by seal arrangement (being plug screw); When fluid needs outer loop, the oil circuit switching port coaxial with through hole is equipped with hollow long oil pipe joint 11, this long oil pipe joint 11 is communicated with upper oil cavitie 9, with this upper oil cavitie 9 and lower oil cavitie 6 are separated, another one oil circuit switching port is equipped with hollow short oil pipe joint 10, and fluid flows out oil pocket from long oil pipe joint 11, through outer loop, flow into from short oil pipe joint 10, flow out by pressure lubrication passage A again.
When speed changer only is operated in the pressure lubrication pattern, as shown in Figure 1, use screw plug 4 and the first seal washer 5 with two tapped holes sealings of lower oil cavitie 6 bottoms.Through hole 7 on the dividing plate 8 is open at this moment, and the pressure oil in the upper oil cavitie 9 enters thus 6, two oil pockets of lower oil cavitie and is connected.Pressure oil from transmission oil pump directly enters lower oil cavitie 6, and by the pressure lubrication passage A that communicates with this oil pocket to carrying out pressure lubrication in the speed changer.
When speed changer work is formerly forced to cool off rear pressure lubrication pattern, as shown in Figure 2, two tapped holes of speed changer oil pocket bottom are installed short oil pipe joint 10, long oil pipe joint 11, oil connection is hollow structure, and its end of being combined with speed changer seals with seal washer, and the other end links to each other with the pipeline of speed changer sink.Wherein long oil pipe joint 11 passes first the tapped hole of oil pocket bottom, pierces into the through hole 7 of lower oil cavitie again, and the shaft shoulder of long oil pipe joint 11 is pressed on the second seal washer 12 on the dividing plate 8 of upper lower oil cavitie, and this moment, lower oil cavitie 6 and upper oil cavitie 9 were by separately.After entering upper oil cavitie 9 from the pressure oil of transmission oil pump, enter the speed changer sink by long oil pipe joint 11, carry out heat exchange, cooled pressure oil is got back to lower oil cavitie 6 from short oil pipe joint 10, and by the pressure lubrication passage that communicates with this oil pocket to carrying out pressure lubrication in the speed changer.
When speed changer changes to the rear pressure lubrication pattern of first pressure cooling by the pressure lubrication pattern, two screw plugs 4 of dismounting lower oil cavitie bottom and the first seal washer 5 are installed short oil pipe joint 10, long oil pipe joint 11, the first seal washer 5 and the second seal washer 12 and are got final product.
When speed changer changes to the pressure lubrication pattern by pressure lubrication pattern after forcing cooling first, the lower short oil pipe joint 10 of dismounting, long oil pipe joint 11, the first seal washer 5 and the second seal washer 12, two tapped holes that plug screw 4 and the first seal washer 5 are installed in the oil pocket bottom get final product.
The utility model has the advantage of: the utility model oil pocket can make transmission oil pump switch between different mode of operations according to the needs of different operating modes easily.The part of changing during switching is few, and the part of changing only need pull down two plug screws or two oil connections all in the outside of speed changer, and is very convenient.
The above only is a kind of mode of execution of the present utility model, it or not whole or unique mode of execution, the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model specification is claim of the present utility model and contains.
