Description
Technical field
The utility model relates to a kind of anti-band row power take-off for used with tractor, is mainly used in the working conditions such as rotary tillage, belongs to Power output technical field.
Background technique
In existing tractor transmission system, realize joint and the disconnection of Power output mainly through following two kinds of modes:
First kind of way adopts shifting fork structure, and this kind of mode drives tooth cover to slide by shift fork, and realize gear switch, its gearshift is wasted time and energy, and needs the cooperation of dry wet clutch could realize gearshift.
The second way adopts wet clutch structure, this wet clutch gearshift rapid and convenient, but if single clutch configuration, when gear is thrown off, band row phenomenon can occur because of the fluid adhesion between friction plate.
For preventing the band row phenomenon of the second way, prior art adopts the following two kinds scheme.A kind of scheme is: increase drum brake at output terminal; Another kind of scheme is: in power take-off, adopt two cover clutch configurations, and the second cover clutch is used for braking.Need distinguish the opening and closing of solenoidoperated cluthes and drum brake during last scheme gearshift, complex operation, and two covering devices has the hidden danger interfered; A rear scheme then needs two-way hydraulic oil to control, and control system is complicated, and structure is too fat to move, also has the hidden danger interfered.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provide a kind of structure simple, easy to use and reliable, gearshift rapid and convenient, possess anti-band row function, control system can be avoided mutually to interfere, compact mechanical structure, space hold is few, is beneficial to the used with tractor anti-band row power take-off of complete machine integral arrangement.
The purpose of this utility model has been come by following technical solution, a kind of used with tractor anti-band row power take-off, it comprises one and is bolted on shell on main-gear box body, be mounted with one in described shell and be fixed on input gear on main box body output shaft by spline, one driving gear engaged with input gear is arranged on power take-off clutch shaft by bearing, gear there is external splines, with clutch inner attrition piece spline fitted;
One is arranged on the clutch on described power take-off clutch shaft, and its outside friction disc is matched by spline with clutch outer member; At least side of inner attrition piece and outside friction disc is mounted with one and is stressed the piston that oil promotes, and can make to be between inner attrition piece and outside friction disc and compress or throw off two states under configuration spring action; Clutch shaft described in described clutch outer member is connected by internal spline, is connected in the output end of clutch shaft the output flange that power spreads out of.
As preferably: described shell is made up of upper shell and lower casing; Described clutch outer member is connected to break inner attrition piece by external splines, and the break outside friction disc matched with break inner attrition piece is matched by spline with brake shell, and described brake shell is bolted on shell.
It is simple that the utility model has structure, easy to use and reliable, gearshift rapid and convenient, possesses anti-band row function, control system can be avoided mutually to interfere, compact mechanical structure, space hold is few, be beneficial to the features such as complete machine integral arrangement, the equipment that it can be avoided clutch and break to occur interfering and cause the adverse consequencess such as car.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, a kind of used with tractor described in the utility model anti-band row power take-off, it comprises one and is bolted on shell on main-gear box body, be mounted with one in described shell and be fixed on input gear 2 on main box body output shaft 3 by spline, one driving gear 12 engaged with input gear 2 is arranged on power take-off clutch shaft 8 by bearing 11, gear 12 there is external splines, with clutch inner attrition piece 15 spline fitted;
One is arranged on the clutch on described power take-off clutch shaft 8, and its outside friction disc 14 is matched by spline with clutch outer member 18; At least side of inner attrition piece 15 and outside friction disc 14 is mounted with one and is stressed the piston 17 that oil promotes, and can make to be between inner attrition piece 15 and outside friction disc 14 and compress or throw off two states under configuration spring 16 acts on; Clutch shaft 8 described in described clutch outer member 18 is connected by internal spline, is connected in the output end of clutch shaft 8 output flange 25 that power spreads out of.
Shown in figure, described shell is made up of upper shell 1 and lower casing 21; Described clutch outer member 18 is connected to break inner attrition piece 30 by external splines, the break outside friction disc 31 matched with break inner attrition piece 30 is matched by spline with brake shell 19, and described brake shell 19 is bolted on shell.
Embodiment: shown in Fig. 1, power take-off described in the utility model, its shell is bolted on main-gear box body.Shell is made up of upper shell 1 and lower casing 21;
Described power take-off, its input end power is by a pair gear, and namely input gear 2 and driving gear 12 engage transmission and enter, and its output terminal is connected to external equipment by flange 25;
A pair described gear, input gear 2 is fixed on main box body output shaft 3 by spline, and driving gear 12 is arranged on power take-off clutch shaft 8 by bearing 11, and driving gear 12 has external splines, with clutch inner attrition piece 15 spline fitted.
One friction clutch, its outside friction disc 14 is matched by spline with clutch outer member 18; During work, clutch plunger 17 oil that is stressed promotes, and compresses outside friction disc 14,15 in clutch, makes the power of gear 12 be transferred to clutch outer member 18 by outside friction disc in clutch 14,15; During stopping, clutch plunger 17 promotes by spring 16, and inside and outside clutch friction plate 14,15 is thrown off, and cuts off power transmission.
Described clutch outer member 18 has internal spline, and the clutch shaft 8 described in connection, power is delivered on flange 25 eventually through clutch shaft 8.
Described clutch outer member 18 there is external splines, connecting brake inner attrition piece 30.
One break, its outside friction disc 31 is matched by spline with brake shell 19.Described brake shell 19 is bolted on power take-off shell 21.During work, brake plunger 29 be stressed oil promote, brake bush is thrown off, can not Power output be interfered.During stopping, brake plunger 29 promotes by spring 28, compresses clutch friction plate 30,31, prevents clutch outer member 18 from rotating, and namely prevents the generation of the row's of being with phenomenon.
Working principle of the present invention is:
Operating mode one, oil duct leads to oil and realizes Power output, and piston 17 promotes by oil duct 7 fluid, and outside friction disc 14,15 in compressing, makes it to be combined with each other, by transmission of power to clutch outer member 18; Brake plunger 29 promotes by the fluid of oil duct 20 simultaneously, and interior outside friction disc 30,31 is thrown off mutually.Now, Power output route is: main box body output shaft 3 → input gear 2 → driving gear 12 → clutch outer member 18 → clutch shaft 8 → flange 25.
Operating mode two, oil duct oil-break power does not export, and piston 17 promotes by spring 16, and interior outside friction disc 14,15 is thrown off mutually, and power disconnects; Brake plunger 29 promotes by spring 28 simultaneously, interior outside friction disc 30,31 is be combined with each other, thus is fixed by clutch outer member 18, prevent it from rotating.Now, if band row occurs interior outside friction disc 14,15, break will stop clutch outer member 18 transfer, thus play the effect of anti-band row.
So-called hydraulic interlock, namely by the break-make of an oil circuit control, solenoidoperated cluthes work simultaneously, break is thrown off; Throw-out-of clutch, brake operation.
