Description
Technical field
This patent relates to a kind of new work transmission built-in braking clutch combination unit, for realizing braking and the clutch Double-linkage of agricultural operation machinery.
Background technique
Between the engine and the gearbox, often need to adopt clutch and break to realize transmission and the interruption of power, but the clutch used at present and break are all installed separately, structure is compact not, and the space occupied by installation is larger.
Summary of the invention
This patent is a kind of new work transmission built-in braking clutch combination unit, the technological scheme that its technical solution problem adopts is: this device is by case of transmission 1, input shaft 2, spring 1 (3), release collar 4, steel ball 5, spring 2 (6), duplex shift fork 7, output gear 8, spring 3 (9), wet brake 10, spring seat 11 is formed, steel ball 5 is placed between the annular space of input shaft 2 and release collar 4 usually, and be positioned at release collar 4 the right and left have the spring 1 (3) of different pretightening force and spring 2 (6) act under by spring seat 11 wedging, release collar 4 and external splines overlap 4a and make one, output gear 8 overlaps 4a by internal spline and external splines and engages, duplex shift fork 7 is by shift fork handle 7a, declutch shift shaft 7b, shift fork 7c, shift fork 7d is welded, declutch shift shaft 7b is through release collar 4.
Wet brake 10 is made up of brake hub 10c, friction plate 10b, platen 10a, the hub 10c of wet brake can move axially to the right with brake bush 10b and compress the pressing plate 4b of external splines cover 4a the inner, and the pretightening force that platen 10a overcomes spring 3 (9) makes its four boss be pressed into the respective slot 1a of case of transmissions 1.
The beneficial effect of this patent is: break and clutch pack are integrated, and operator's action once can complete separation function and the braking function of clutch simultaneously.Compact structure, saves installing space, reduces the labor intensity of operator.
Accompanying drawing illustrates:
Fig. 1 is the schematic diagram that the speed changer built-in braking clutch combination unit clutch of this patent engages.
The schematic diagram that Fig. 2 is the speed changer built-in braking clutch combination unit clutch separation of this patent, break plays braking action.
In figure, 1. case of transmission, 2. input shaft, 3. spring Isosorbide-5-Nitrae. release collar, 5. steel ball, 6. spring 2,7. duplex shift fork, 8 output gears, 9. spring 3,10. wet brake, 11. spring seats.
Embodiment
Duplex shift fork 7 is by shift fork handle 7a, declutch shift shaft 7b, shift fork 7c, shift fork 7d is welded, declutch shift shaft 7b is through release collar 4, release collar 4 and external splines overlap 4a and make one, output gear 8 overlaps 4a by internal spline and external splines and engages, the shift fork 7d of usual duplex shift fork 7 leans in release collar 4, thus overcome the pretightening force of spring 2 (6) and spring 1 (3), wedging in the annular space of steel ball 5 between input shaft 2 and release collar 4 is made by spring seat 11, power from input shaft 2 through steel ball 5, release collar 4 and do with it all-in-one-piece external splines cover 4a pass to output gear 8.
Wet brake 10 is made up of hub 10c, friction plate 10b, platen 10a, stir the shift fork handle 7a of duplex shift fork 7 counterclockwise, shift fork 7d unclamps release collar 4, the pretightening force of spring 1 (3) is greater than the pretightening force of spring 2 (6), therefore promotion release collar 4 moves right, make steel ball 5 between the groove and the groove of input shaft 2 of release collar 4, interrupt from input shaft 2 through the transmission of power of steel ball 5 to output gear 8; Shift fork 7c acts on wet brake 10 simultaneously, promotion friction plate 10b presses against and does on all-in-one-piece pressing plate 4b with release collar 4, platen 10a moves with wet brake 10 simultaneously, overcome the pretightening force of spring 3 (9), in the groove of the boss press-in case of transmission 1a on platen 10a, wet brake 10 braking actions, make output gear 8 reduce rotating speed until slack.
Claims (2)
1. a new work transmission built-in braking clutch combination unit, is characterized in that: by case of transmission (1), input shaft (2), spring 1 (3), release collar (4), steel ball (5), spring 2 (6), duplex shift fork (7), output gear (8), spring 3 (9), wet brake (10), spring seat (11) is formed, steel ball (5) is placed between the annular space of input shaft (2) and release collar (4) usually, and be positioned at release collar (4) the right and left have the spring 1 (3) of different pretightening force and spring 2 (6) act under by spring seat (11) wedging, one made by release collar (4) and external splines cover (4a), output gear (8) is engaged with external splines cover (4a) by internal spline, and duplex shift fork (7) is by shift fork handle (7a), declutch shift shaft (7b), shift fork (7c), shift fork (7d) is welded, and declutch shift shaft (7b) is through release collar (4).
