The utility model is achieved through the following technical solutions:
The utility model relates to a kind of automobile gearbox lubricating structure, this mechanism is arranged in gearbox and is connected in the gearbox rear case, comprise: oil trap, feeding bank and installation buckle, wherein: be connected with the bending type feeding bank of semi open model structure bottom the oil trap of semi open model structure, installation buckles 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 oil trap is arranged at the reverse gear shaft rear bearing of gearbox to the space of rear case inwall, make gearbox inside when high speed rotating, main deceleration follower can take fluid in the space of reverse gear shaft fore bearing direction to, is left in oil trap thereby fluid enters the reverse gear shaft oilhole; Simultaneously, be thrown to fluid on the rear case internal chamber wall because Action of Gravity Field can flow in feeding bank, oil trap is flow through the lubricant oil that comes with feeding bank and the lubricant oil of self collecting delivered to rear bearing, input shaft to the space of rear case inwall, thereby rear bearing, input shaft and whole input shaft assembly are played lubrication.
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 makes the fluid of importing have downward potential energy, in order to play better faster lubrication effect.
The utility model is by arranging an oil guide plate in gearbox.There is two-part oil to be collected and imports in rear bearing, input shaft direction oilhole.One, because the High Rotation Speed of gearbox Lubricants by gear stirs, lubricated oil droplet is attached on the gearbox rear case, and lubricated oil droplet is because the gravity reason is collected in oil guide plate naturally.Its two, due to 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 after rear bearing, input shaft in 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 shift gear, and needle bearing is realized moistening and changed.The utility model has really been 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.
