Above-mentioned horizontal drive shaft is installed on the stands longitudinal center of symmetry, and with antifriction-bearing box supporting two ends axle journal, bearing installation is in bearing seat, and bearing seat is fixed on the frame of vehicle, and described horizontal drive shaft is used telescopic steel pipe sealing.
Above-mentioned transmission gearbox is installed on the frame of vehicle through carriage.
Above-mentioned steering drive axle is installed on the frame of vehicle through carriage.
Above-mentioned transmission gearbox and steering drive axle fuse.
Above-mentioned universal drive shaft below is provided with the transmission shaft guar plate.
Be provided with the arrangement of clutch between output shaft and the universal drive shaft in the above-mentioned propons change speed gear box.
The present invention compares the outstanding advantage of prior art:
1, the middle part of steering drive axle transmission of the present invention increases the universal drive shaft transmission, can all errors that produce because of frame processing be compensated, and has avoided the off-axis phenomenon in use occurring, has improved the reliability and the work efficiency that use;
2, steering drive axle of the present invention is connected with horizontal drive shaft through 1: 1 transmission gearbox, makes that the diff-H between horizontal shaft and the steering drive axle increases the crack, agronomy ground of having improved steering drive axle; The mid-layout of transmission shaft; Crack, road ground is higher, so the reaper crossing ability is good, and range of use is big;
3, front driving axle of the present invention, the hermetically sealed waterproof of steering drive axle, horizontal drive shaft protects with formed in mould steel plate with steel pipe sealing, universal joint shaft, does not twine when guaranteeing harvest operation;
4, the present invention is applicable to various types of reapers.
Description of drawings:
Fig. 1 is a generalized section of the present invention;
Fig. 2 is the A portion enlarged diagram of Fig. 1;
Fig. 3 is the B portion enlarged diagram of Fig. 1.
The specific embodiment:
With specific embodiment the present invention is further described below, referring to Fig. 1-3:
Four-wheel drive axle assembly for harvester; After being positioned at the shifting slide gear and the engagement of two-stage spur wheel at propons change speed gear box main gear driving gear shaft 102 middle parts; It through a pair of transmitting ratio 1: 1 spiral bevel switching-over; Output shaft 101 after the switching-over is connected with an end of universal drive shaft 2; The other end of universal drive shaft 2 is connected with the input end 301 of horizontal drive shaft 3, and the mouth 302 of horizontal drive shaft 3 is connected with the input shaft 401 of transmission gearbox 4, and the input shaft 401 of transmission gearbox 4 drives the output shaft 403 of raising the crack, ground through tween drive shaft 402 switching-over backs and rotates; Output shaft 403 connects steering drive axle 5, and front driving axle 1, transmission gearbox 4 are connected on the frame 9 of vehicle with steering drive axle 5.
Above-mentioned horizontal drive shaft 3 is installed on frame 9 vertical center of symmetrys, and with antifriction-bearing box 8 supporting two ends axle journals, bearing 8 is installed in the bearing seat 801, and bearing seat 801 is fixed on the frame 9 of vehicle, telescopic steel pipe 10 sealings of described horizontal drive shaft 3 usefulness.
Above-mentioned transmission gearbox 4 is installed on the frame 9 of vehicle through carriage 6.
Above-mentioned steering drive axle 5 is installed on the frame 9 of vehicle through carriage 6.
Above-mentioned transmission gearbox 4 fuses with steering drive axle 5.
Above-mentioned universal drive shaft 2 belows are provided with transmission shaft guar plate 7.
Be provided with the arrangement of clutch between output shaft 101 and the universal drive shaft 2 in the above-mentioned propons change speed gear box, this arrangement of clutch can make reaper conversion between 4 wheel driven and two drives.
Principle of work of the present invention is:
The present invention is arranged on the frame 9; After the shifting slide gear at propons change speed gear box main gear driving gear shaft 102 middle parts and the engagement of two-stage spur wheel; Through a pair of transmitting ratio is 1: 1 spiral bevel switching-over, and the output shaft 101 after the switching-over is connected with an end of universal drive shaft 2,2 rotations of drive universal drive shaft; The rotation of universal drive shaft 2 has driven the rotation of horizontal drive shaft 3; Horizontal drive shaft drives the output shaft 403 of raising the crack, ground through tween drive shaft 402 switching-over backs and rotates through being after the input shaft 401 of 1: 1 transmission gearbox 4 is connected with transmitting ratio, and the output shaft 403 of transmission gearbox 4 drives rear driving axles 5; Thereby the imput shaft 102 that has realized the propons change speed gear box is through driving front driving axle 1 and steering drive axle 5 respectively after the speed change, this moment, reaper was a 4 wheel driven; In the propons change speed gear box, be provided with the arrangement of clutch of clutch between imput shaft 102 and the universal drive shaft 2; When arrangement of clutch was pushed aside, the output shaft 101 of propons change speed gear box can only drive front driving axle work, can not drive steering drive axle; At this moment, reaper is two to drive.
The middle part of steering drive axle transmission of the present invention increases universal turning cylinder transmission, can all errors that produce because of frame processing be compensated, and has avoided the off-axis phenomenon in use occurring, has improved the reliability and the work efficiency that use; Steering drive axle is connected with horizontal drive shaft through 1: 1 transmission gearbox, makes that the diff-H between horizontal drive shaft and the steering drive axle increases the crack, agronomy ground of having improved steering drive axle; The mid-layout of transmission shaft; Crack, road ground is higher, so the reaper crossing ability is good, and range of use is big; Front driving axle, the hermetically sealed waterproof of steering drive axle, horizontal drive shaft protects with formed in mould steel plate with steel pipe sealing, universal joint shaft, does not twine when guaranteeing harvest operation; Be applicable to various types of reapers.
The foregoing description is merely one of preferred embodiment of the present invention, is not to limit practical range of the present invention with this, so: all equivalences of doing according to shape of the present invention, structure, principle change, and all should be covered by within protection scope of the present invention.
