Abstract
The utility model discloses a main reducer initiative lubricating structure, a serial communication port, including oily pump cylinder body, oil channel, first oil pump gear and second oil pump gear, first oil pump gear and second oil pump gear set up in oily pump cylinder body, first oil pump gear is connected with the the initiative taper gear cooperation, oil channel one end and mistake axle case lid inner wall oil through intercommunication, the oil channel other end and inter axle differential assembly intercommunication. The technical scheme of the utility model can pass through the lubricating oil in the main reducer shell oil channel carries inside the inter axle differential assembly to go on effectively lubricatedly to the inter axle differential assembly, improve each part life of axle greatly.
Description
Technical field
The utility model relates to auto parts machinery field, relates in particular to initiatively lubrication system of a kind of main reducing gear.
Background technology
Main reducer of middle axle structure used in the market, does not substantially all have initiatively lubrication system, and this has just caused masterInter-axle differential assembly oil-feed difficulty in decelerator, lack of lubrication, and then cause inter-axle differential gear and bearing dry grinding, damageThe noise of the inner spare and accessory parts of bad vehicle bridge and increase vehicle bridge.
Summary of the invention
The defect or the deficiency that exist for prior art, the utility model has proposed a kind of novel main deceleration innovativelyDevice is lubrication system initiatively, the lubricating oil in final drive casing can be transported in inter-axle differential assembly by oil transportation channelPortion, thus inter-axle differential assembly is carried out to effectively lubricating.
The technical solution of the utility model is achieved in that
A kind of main reducing gear is lubrication system initiatively, it is characterized in that, comprises Oil pump cylinder, cylinder cap-blocking, oil transportation channel, theOne oil pump gear and the second oil pump gear, described the first oil pump gear and the second oil pump gear are arranged in Oil pump cylinder, described inThe first oil pump gear and drive bevel gear are connected, and described oil transportation channel one end is communicated with gap bridge cover wall oil through, instituteStating the oil transportation channel other end is communicated with inter-axle differential assembly.
Further, described Oil pump cylinder is bolted on bridge case and covers.
Further, between described oil transportation channel and gap bridge cover wall oil through, be also provided with screen pack.
Further, described the first oil pump gear and the second oil pump gear are fixed in Oil pump cylinder by straight pin.
Further, described the first oil pump gear is connected by movable block with drive bevel gear.
Further, described movable block is fixedly connected with by pin with drive bevel gear.
Compared with prior art scheme, the beneficial effects of the utility model are:
The technical solution of the utility model can be transported between centers by oil transportation channel by the lubricating oil in final drive casingDifferential assembly inside, thus inter-axle differential assembly is carried out to effectively lubricating, greatly improve the each parts of vehicle bridge service life.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried outDescribe clearly and completely, obviously, described embodiment is only the utility model part embodiment, instead of wholeEmbodiment. Based on the embodiment in the utility model, those of ordinary skill in the art are not making under creative work prerequisiteThe every other embodiment obtaining, belongs to the scope that the utility model is protected.
As shown in Figure 1 and Figure 2, the utility model provides initiatively lubrication system of a kind of main reducing gear, comprise Oil pump cylinder 1,Cylinder cap-blocking 15, oil transportation channel 11, the first oil pump gear 2 and the second oil pump gear 3, Oil pump cylinder 1 was bolted onOn bridge case lid 5; The first oil pump gear 2 and the second oil pump gear 3 are fixed in Oil pump cylinder 1 by straight pin 8, the first oil pump toothWheel 2 is connected by movable block 9 with drive bevel gear 4, and movable block 9 is fixedly connected with by pin 10 with drive bevel gear 4, thereby makesDrive bevel gear 4 while rotating, can drive the first oil pump gear 2 to rotate. Oil transportation channel 11 one end and gap bridge cover wall are logicalOilhole 6 is communicated with, and between oil transportation channel 11 and gap bridge cover wall oil through 6, is also provided with screen pack 7, and screen pack 7 structures canIron filings in filtering lubricant oil and residue, be inhaled in oil transportation channel 11 limpider lubricating oil, another of oil transportation channel 11End is communicated with inter-axle differential assembly 12, lubricating oil can be prolonged to oil transportation channel 11 and be transported in inter-axle differential assembly, passes a bridgeCase lid 5 is bolted to connection with final drive casing, and bridge case cover cavity 13 has intercommunicating pore with final drive casing inner chamber 14, withThe lubricating oil of being convenient to final drive casing chamber flow into bridge case cover cavity 13.
In the time that automobile is exercised, initiatively lubrication system is started working, and drive bevel gear 4 is rotated and driven the first oil pump gear 2 to turnMoving, thus the lubricating oil of final drive casing inside is drawn in gap bridge case lid 5, then enter through gap bridge cover wall oil through 6In the oil transportation channel 11 of active lubrication system, between oil transportation channel 11 and gap bridge cover wall oil through 6, be also provided withFilter screen 7, when lubricating oil enters oil transportation channel 11, filters out iron filings and residue in filter lubricating oil, makes limpider profitLubricating oil is inhaled into, then after the first oil pump gear 2 and the second oil pump gear 3, along oil transportation channel 11, lubricating oil is transported to axleBetween in the oil transportation channel of differential assembly inside, thereby inter-axle differential assembly is lubricated.
The direction of lubricating oil flow when the technical solution of the utility model of direction indication shown in arrow is worked in Fig. 2.
The foregoing is only the preferred embodiment of invention, not in order to limit the utility model, all new in this practicalityWithin the spirit and principle of type, any amendment of doing, be equal to replacement, improvement etc., all should be included in protection of the present utility modelWithin scope.
