Description
Technical field
What the present invention relates to is a kind of device of vehicle transmission technology neck, specifically a kind of automobile gearbox lubricating structure.
Background technique
Nowadays, automobile has become the traffic tool indispensable in people's daily life and the industrial and agricultural production.And the quality of automobile gearbox is driven and is being played the part of important role in the experience affecting the Consumer.Inner at automotive transmission, the engagement driving of gear box internal gear affects the working life of part in the case greatly so that temperature and the hurried rising of air pressure in the casing.Then seem and be even more important so how effectively each component is lubricated.
General speed changing box lubricating system all is to store a certain amount of lubricating oil in gearbox, and then the High Rotation Speed by the gearbox gear wheel set stirs lubricant oil, and the lubricant oil that splashes splashes into needs lubricated gearbox parts, takes the mode of splash lubrication to realize.At first, the component that general gearbox need to lubricate have gear, axle and bearing etc.; Secondly the component speed that needs profit to change is higher, and is high for lubricating requirement; Again, because gearbox designs is complicated, some parts usually take some special constructions to realize, but often lubrication effect are undesirable because structural limitations often exists lubricated dead band.In a word, conventional speed changing box lubricating system complex structural designs, and lubrication effect is not good.
Find through the retrieval to prior art, Chinese patent literature CN101463896, open day 2009-06-24, put down in writing a kind of " lubrication apparatus of speed changer ", this device is arranged in the speed changer and is connected with the speed changer rear case with the speed changer front case, described oil guide plate comprises oil guide slot and feeding bank, the lead to passage of respectively treating lubricating component of described feeding bank for drawing from oil guide slot, and the feeding bank end is provided with oil outlet.Transmission oil liquid stirs by the High Rotation Speed of gear, because the lubricated oil droplet that Action of Gravity Field splashes is collected in the oil guide plate, the lubricant oil that is collected is assigned to needs lubricated each shifting gear, differential mechanism master slow down driven gear, axle and bearing, can realize that by adopting lubricating fitting of the present invention above-mentioned parts are carried out active to be lubricated.But the prior art mechanism is complicated, is difficult to really apply in the actual production, and its two this lubricating fitting can only be collected the fluid of splash lubrication, they are three years old, this lubricating fitting, is difficult to that fluid is led this place and plays lubrication effect as embedding housing bearing place for lubricated dead band.
Summary of the invention
The present invention is directed to the prior art above shortcomings, a kind of automobile gearbox lubricating structure is proposed, lubricant oil collection and distribution function by this mechanism, making needs each lubricated component can both reach satisfied lubrication effect, and this mechanism has overcome the low and baroque disadvantage of traditional gearbox lubricating efficiency, can not only collect the fluid of splash lubrication and can from the reverse gear shaft oilhole, collect fluid, simultaneously fluid is imported to the bearing lubrication dead band, can play sufficient lubrication to bearing, prolong the life-span of bearing, lubrication effect is more remarkable.
The present invention is achieved by the following technical solutions:
The present invention relates to a kind of automobile transmission lubrication mechanism, this mechanism is arranged in the gearbox and is connected in the gearbox rear case, comprise: oil trap, feeding bank and installation buckle, wherein: the oil trap bottom of semi open model structure links to each other with the bending type feeding bank of semi open model structure, installs to buckle and the vertical side that is connected and is positioned at the nearly oil trap in bending place of feeding bank.
Described oil trap is comprised of open cavity and the open output duct of semicircular structure, wherein: the entrance of oil trap is arranged at the center of circle of the semicircular structure of open cavity, open output duct is arranged at a side of open cavity, and the edge of open cavity corresponding to the side is provided with rib.
Described feeding bank is that the long and short conduit of L character form structure forms, and the long duct of feeding bank is the two-part structure and connects by bending, and such design is so that the fluid that imports has downward potential energy, in order to play better faster lubrication effect.
The present invention is by arranging an oil guide plate in gearbox.There is two-part oil to be collected and imports in the rear bearing, input shaft direction oilhole.One stirs because the gearbox Lubricants passes through the High Rotation Speed of gear, and lubricated oil droplet is attached on the gearbox rear case, and lubricated oil droplet is owing to the gravity reason is collected in the oil guide plate naturally.Its two because the differential mechanism High Rotation Speed, lubricant oil is collected in the oil trap of oil guide plate by the all-pass oilhole of reverse gear shaft.The oil that these two-part are collected can be sent to behind the rear bearing, input shaft in the end spaces along feeding bank, at first can be lubricated rear bearing, input shaft, after collecting a certain amount of oil, the oilhole that fluid can pass through input shaft is to each shifting gear, and needle bearing is realized moistening and changed.The present invention has really accomplished the cyclic process of gearbox internal lubricating system, has solved the problem that there is lubricated dead band in the gearbox part or is difficult to lubricate with conventional method, the working life that can effectively improve each component of gearbox.
