End is connected to shift fork axle respectively.
The application method of the utility model is to be mounted on the oil pumping device of speed changer bottom shell inner wall for speed changer bottom
Lubricating oil be pumped into inside main tank shift fork axle and odd-side shift fork axle by oil pipe, lubricating oil is dialled by main tank shift fork axle and odd-side
The oil groove opened up on fork shaft is ejected on the gear and friction pair of oil groove face.
Compared with prior art, the utility model has the following beneficial effects:
The lubricating oil of speed changer bottom is passed through oil pipe using the oil pumping device for being mounted on speed changer bottom by the utility model
It is pumped into inside the cavity of shift fork axle, if offering dry sump, oil groove and shift fork axle cavity close to the side of gear in shift fork axle
Connection, each oil groove positions are answered with the gear mesh immediately below it, and then lubricating oil is ejected into and face below oil groove from oil groove
Each gear and main friction pair on.The utility model opens up several and bottom cog face oil in shift fork axle
Lubricating oil can be ejected into each gear and main friction pairs by slot, it is ensured that comprehensive lubrication of speed changer, even if becoming
Under severe operating conditions, the lubrication needs of speed changer also may be implemented in fast device；Meanwhile oil pipe being directly connected to and opens up oil
In the shift fork axle of slot, the space of gearbox is effectively saved, meets the design requirement of gearbox lightness and miniaturization.
Further, the utility model offers cylindrical hole in shift fork axle centered on its axis, such good
Place is that through-hole is opened up centered on axis, can both guarantee the uniform force of shift fork axle, and through-hole again can will be in lubricating oil
Impurity discharge prevents from blocking the oilhole of shift fork axle, even if there is impurity to block the oilhole of shift fork axle, also facilitate tamper is clear
It removes.
Further, the oil pipe of the utility model can thus may be used with more main tank shift fork axles and odd-side shift fork axis connection
With the different demands according to different speed changers to degree of lubrication, oil pipe and main tank shift fork axle and odd-side shift fork can be increased or decreased
The connection quantity of axis, both can guarantee the lubrication needs for meeting speed changer, for do not need lubrication component, and be avoided that it is unnecessary
Lubrication, save lubricating oil, save speed changer space.
Further, the oil groove in the utility model shift fork axle is provided with the side close to gear, and with below shift fork axle
The setting of gear face, lubricating oil may be implemented to the accurate injection of transmission gear lubrication.
Further, the oil pipe of the utility model is solid pipe, and convenient for the location and installation inside gearbox, oil pipe is close to become
Fast device inner walls setting, saves the inner space of speed changer, meets the design requirement of gearbox lightness and miniaturization.

Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is described in further detail:
As depicted in figs. 1 and 2, a kind of transmission lubrication system structure, including oil pumping device 4, oil pipe 3, one end of oil pipe 3
Connect with the output end of oil pumping device 4, the other end with it is internal be that the shift fork axle 1 of cavity structure is connect, i.e. oil pipe 3 is by shift fork axle 1
It is connected to oil pumping device 4, circulation of the lubricating oil in gearbox thus may be implemented.Because lubricating oil is in the bottom of speed changer,
So oil pumping device 4 to be mounted on to the bottom shell inner wall of speed changer, for pumping lubricating oil to lubricating system.Preferably, it dials
The internal cavities of fork shaft 1 open up cylindrical through-hole, through-hole aperture size along the axis direction of shift fork axle 1 using axle center as the center of circle
Match with the caliber of oil pipe 3, oil pipe 3 usually selects metal tube, and oil pipe 3 is close to the setting of case of transmission inner wall, according to speed change
One end of oil pipe 3 can be inserted into the through-hole of shift fork axle 1 in this way, and then oil pumping device 4 is pumped by device internal structure bending and molding
The lubricating oil sent is transported to the inside of shift fork axle 1 by oil pipe 3；If in addition, the side in shift fork axle 1 close to gear offers
Dry sump 5, and oil groove 5 is opened up in the position with gear face, it is such be provided be conducive to by the lubricating oil inside shift fork axle 1 from
It after oil groove 5 ejects, can guarantee that lubricating oil is ejected into each gear and main friction pairs, realize to the complete of speed changer
Face lubrication.
Because speed changer has more shift fork axles 1, including main tank shift fork axle 101 and odd-side shift fork axle 102, different speed changers
The quantity of shift fork axle 1 is also different, and different speed changers also has nothing in common with each other to the actual demand of lubrication.Oil pipe 3 is from oil pumping device 4
Output end is a main line connection, and when close to shift fork axle 1, the main line of oil pipe 3 is just branched into and the comparable branch of 1 quantity of shift fork axle
Road binders pipe, a branch oil pipe are correspondingly connected with a shift fork axle 1.Therefore, according to the practical lubrication needs of speed changer, Ke Yixuan
The connecting oil pipe 3 with corresponding main tank shift fork axle 101 and odd-side shift fork axle 102 of selecting property, in this way can be targetedly to change
Fast device needs the position lubricated to be lubricated comprehensively.
In conclusion a kind of application method of the utility model are as follows: be mounted on the pump oil dress of speed changer bottom shell inner wall
It sets 4 to be pumped into the lubricating oil of speed changer bottom inside main tank shift fork axle 101 and odd-side shift fork axle 102 by oil pipe 3, lubricating oil
It is ejected on the gear and friction pair of 5 face of oil groove by the oil groove 5 opened up in main tank shift fork axle 101 and odd-side shift fork axle 102.
