The utility model discloses a lubrication structure of a double-middle-shaft type manual transmission, which comprises a transmission casing and middle shafts, the transmission casing is equipped with a bearing seat, ends of the middle shafts are supported in the bearing seat through bearings, the bottom portion of the bearing seat is equipped with an oil storage groove, an oil baffle partition board is arranged approaching the bearing seat, an oil guide groove leading to the oil storage groove is arranged close to the oil baffle partition board, the middle shafts are equipped with lubrication oil passages communicated with the oil storage groove, and the surfaces of the middle shafts are equipped with a plurality of lubrication oil holes communicated with the lubrication oil passages. Swashing lubrication oil is baffled by the oil baffle partition board, flows into the oil storage groove through the oil guide groove, constantly flows into the lubrication oil passages of the middle shaft under pressure, and then flows out from the lubrication holes to lubricate needle bearings supporting change gears. The lubrication structure can be utilized to guarantee the lubrication oil to efficiently enter the lubrication oil passages of the middle shafts, can meet lubrication requirements by only small lubrication oil quantity, simultaneously increases the lubrication reliability, and efficiently prolongs the service life of the transmission.

Description

The lubricating structure of shaft type manual speed transmission in the middle of two
Technical field
The utility model relates to the lubrication system of speed changer, more particularly, relates to a kind of structure that the needle bearing that supports change gear in the shaft type manual speed transmissions in the middle of two is lubricated of being used for.
Background technique
Manual transmission generally is installed between the clutch and transmission shaft of vehicle, by changing the excursion that velocity ratio enlarges vehicle drive force and speed, to adapt to the driving conditions of frequent variation, simultaneously motor is worked under best condition.
The lubricated of manual transmission generally realized by the rotation drive lubricating oil splash of internal gear, but because the lubricant oil that sputters is limited, the lubricated cooling effect of this mode is unsatisfactory, cause the speed changer internals to produce high temperature and wearing and tearing, the needle bearing that particularly supports change gear causes early failue owing to can not get sufficient lubrication when being everlasting the speed changer running, have a strong impact on the working life of speed changer.
The model utility content
The technical problems to be solved in the utility model provides a kind of lubricating structure of two middle shaft type manual speed transmissions, to improve the lubrication effect that supports the needle bearing of change gear in the manual transmission, prolongs the working life of speed changer.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of lubricating structure of two middle shaft type manual speed transmissions, comprise case of transmission and jack shaft, described case of transmission is provided with bearing support, the end of described jack shaft by bearings in bearing support, the bottom of described bearing support is provided with oil storage tank, be provided with the oily dividing plate of retaining near the bearing support, have the oil guide slot of leading to oil storage tank near keeping off oily dividing plate, described jack shaft is provided with the oil leab that is connected with oil storage tank, and the surface of jack shaft is provided with a plurality of oilholes that communicate with oil leab.
The manual transmission internal gear rotates and drives lubricating oil splash, the lubricant oil that splashes is kept off oily dividing plate interception, flows into oil storage tank by oil guide slot, constantly flows into the oil leab of jack shaft under pressure, flow out from oilhole then, the needle bearing everywhere that supports change gear is lubricated.Two jack shafts of two middle shaft type manual speed transmissions described in the utility model all adopt this kind lubricating structure that needle bearing is lubricated.Utilize this lubricating structure, can guarantee that lubricant oil effectively enters the oil leab of jack shaft, only need compare lubricants capacity still less, can satisfy lubricating requirement, increased lubricating reliability simultaneously with general manual transmission, significant prolongation the working life of speed changer.
Preferably, be provided with the Oil Guide mouth in bearing support, described Oil Guide mouth is communicated with described oil leab and oil storage tank.Since the existence of Oil Guide mouth, the relatively independent space of the inner formation of the oil leab of jack shaft, and during speed changer work, this interior volume pressure is lower than the case of transmission internal pressure, thereby lubricant oil can be flowed in the oil leab continuously.
Further, described Oil Guide mouth is a disc, and its center portion is provided with oil guide pipe, and the circumferential edges of Oil Guide mouth is clamped between bearing outer ring and the bearing support bottom surface, and oil guide pipe inserts in the oil leab of jack shaft.
More preferably, described Oil Guide mouth is a metallic stamping pieces.
