[embodiment]
Below in conjunction with accompanying drawing, the present invention is described in further detail:
See Fig. 2, the transmission lubrication system of band through shaft power take-off of the present invention, comprise speed changer one axle 12, one axle 12 is connected with a shaftgear 13, oil pump 18, countershaft-gear 16 are connected on jack shaft 15, and power is delivered to oil pump 18 by an axle 12 through a shaftgear 13, countershaft-gear 16, jack shaft 15, and lubricant oil is sucked oil pump by the second oil inlet passage 17 by oil pump 18, by lubricant pipe 14, lubricant oil is pumped into speed changer inside, oilgear bearing etc.
Through shaft power take-off is connected on speed changer bonnet 19, and input shaft 1 is connected by spline 22 with transmission countershaft 15.Owing to being interconnected by means of only connecting passage 11 between through shaft power take-off and speed changer, speed changer internal lubrication oil level is lower than connecting passage 11 times edges, cause lubricant oil can not flow into through shaft power take-off inner, when speed changer running or vehicle descending, situation is more severe.
The present invention arranges output oil pipe 20 in speed changer rear end, and output oil pipe 20 one end is connected with lubricant pipe 14 through bonnet 19, and it is inner that the other end enters through shaft power take-off, replaces oil discharge passage 3 that lubricant oil is pumped into through shaft power take-off.Utilize transmission oil pump 18 to meet speed changer and through shaft power take-off lubrication needs simultaneously, thus cancel the power take-off oil pump 4 of through shaft power take-off own.
Simultaneously, the present invention is connected with bottom through shaft power take-off by circulating pipe 21 one end, the other end is connected with bottom speed changer, by circulating pipe 21, guarantee that through shaft power take-off internal lubrication oil level is not higher than speed changer internal liquid level, reduce the inner churning loss of through shaft power take-off, raising efficiency, reduces temperature rise.
Principle of the present invention:
As shown in Figure 1, Fig. 1 is traditional through shaft power take-off, its driving gear 2 and power take-off oil pump 4 are connected with input shaft 1, power drives driving gear 2 and power take-off oil pump 4 to rotate through input shaft 1, lubricant oil is sucked oil pump by the first oil inlet passage 5 be connected with speed changer by power take-off oil pump 4, pumps into through shaft power take-off and then lubrication, cooled interior part by oil discharge passage 3; The driving gear 2 of through shaft power take-off drives driven gear 8, and driven gear 8 is connected with output shaft 7, and output shaft 7 is by output flange 6 outputting power, and output shaft 7 shift fork axle 9 rotates, and cylinder 10 promotes declutch shift shaft 9 transverse shifting.
Connecting passage between speed changer and through shaft power take-off is very little and power take-off mounting point is higher, causes lubricant oil to be difficult to flow directly into power take-off inside.Meanwhile, the structure comparison of power take-off is compact, and inner space is narrow and small, and the lubricants capacity that power take-off inside can store is little, if power take-off and speed changer internal lubrication oil can not be allowed to circulate, and the inefficacy apt to deteriorate of power take-off internal lubrication oil.Therefore, through shaft power take-off usual separate configurations one oil pump, pumps into power take-off by lubricant oil in speed changer, is then back to speed changer inside through connecting passage, reaches the effect of lubrication, cooling, circulation.
During due to vehicle operation, oil pump works always, lubricant oil can pump into through shaft power take-off always, and lubricant oil can only be back to speed changer (connecting passage higher than lubricant oil liquid level in speed changer, during transmission duty through connecting passage, gear stir oil effect under, speed changer internal lubrication oil level is lower), make power take-off internal lubrication oil level too high (concordant with connecting passage), cause power take-off gear churning loss larger, heating value is large, reduces power take-off efficiency.For addressing this problem, utilizing law of connected vessels, being connected bottom power take-off with bottom speed changer, guarantee that namely both liquid level maintenance level reduce power take-off internal lubrication oil level height, and then reduce the churning loss of power take-off, raise the efficiency.
Above content is only and technological thought of the present invention is described; protection scope of the present invention can not be limited with this; every technological thought proposed according to the present invention, any change that technological scheme basis is done, within the protection domain all falling into claims of the present invention.
