Abstract
The utility model relates to a novelconnected rear axle speed-changing box with six stages, composed of a box casing, gears, axles, a bearing, and a differential mechanism, etc. The utility model is characterized in that the connected rear axle speed-changing box with six stages adopts automobile gearbox layout, increases a reversing axle, and changes the four-axle structure of a traditional connected back axle speed-changing box; the speed-changing box changes traditional four-axle into five-axle, effectively uses the space in the speed-changing box body, and makes each gear and axle have more reasonable stress and more compact structure in the condition of little change. As a consequence, the speed-changing box greatly enhances drive stationarity and loading capacity of an agricultural transport vehicle. The gear arrangement in the box casing thoroughly optimizes a low speed gear, and a big speed reducing ratio gear approaches the inner wall of the box body, and this can increase the hardness of axles. As a consequence, the connected rear axle speed-changing box with six stages overcomes abuses that the traditional speed-changing box is easy to drop gear and get out of gear, and the drive gear is easy to impact tooth. The connected rear axle speed-changing box with six stages of the utility model has more convenient shifting operation, and more reasonable gear allocation; as a consequence, the utility model overcomes the abuse that the existing agricultural transport vehicle connected rear axle speed-changing box has higher reverse speed, which can greatly enhance the use performance and economic performance of vehicles.
Description
Technical field
The utility model belongs to the agricultural transportation vehicle field, is specially a kind of novel six grades of connected rear axle gearboxes.
Background technique
At present, the connected rear axle gearbox that uses on the well-known agricultural transportation vehicle has 4+1 shelves or 5+1 shelves, wherein contains a reverse gear.It is very unreasonable that the speed of a motor vehicle is distributed, and especially one grade and reverse speed are higher, and the first gear speed height causes grade ability to reduce, and it is not steady to start to walk; The reverse speed height is handled difficulty, drives very dangerous under the narrow or crowded situation of path space.And the drive path of present existing each grade of connected rear axle gearbox gear is unreasonable, causes each unbalance stress to engaging gear easily, cause out of supply, lose rank, gear is beaten tooth and the phenomenon of premature wear.
Summary of the invention
The purpose of this utility model is by optimizing the drive path of each grade gear, solve forward gears speed allocation problem preferably, reduce by one grade and reverse speed, improving novel six grades of connected rear axle gearboxes of bearing capacity.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel six grades of connected rear axle gearboxes are made up of case shell, gear, axle, bearing and differential mechanism etc., be characterized in being equipped with on the power input shaft 1 IV, V shelves slippage duplicate gear 3 and 4, in the duplicate gear 3 is V shelves gears, the 4th, IV shelves gear, the gear 3 of realizing respectively moving to left produces the V shelves with gear 20 engagements, and the gear 4 that moves to right produces the IV shelves with gear 17 engagements; The right-hand member of power input shaft 1 is equipped with steel wire card 5 and gear 6, and gear 6 often meshes with the gear 8 that is positioned at two 9 right-hand members, and shifting slide gear 7 is contained in two 9 right-hand member, and when shifting slide gear 7 was turned left slippage, one grade of generation was meshed with the gear 14 that is contained in gear shaft 13 right-hand members; When shifting slide gear 7 is turned right slip, produce reverse gears with 12 engagements of reverse gear on the reverse gear shaft 10; The II of two 9 left ends, III shelves duplicate gear 2 and 24, turn right gear 2 and gear 21 engagement generation II shelves when sliding, turning left, gear 24 produces the III shelves with gear 22 engagements when sliding; Gear 23 is normal engagement with gear 21, and gear shaft 13 and gear 15 are normal engagement, lay respectively at the right part of gear shaft 13 and axle 16, and gear 20 and differential mechanism gearwheel 19 also are normal engagement, and lay respectively at the left end of axle 16 and the A wall of gearbox case shell 18.
The utility model has the advantages that overcome gear layout that present six grades of connected rear axle gearboxes exist unreasonable cause gear box wide, one grade and reverse speed is higher and easily lose rank, out of supply and drawback that driving gear is easily beaten tooth, this structure has adopted the automobile gearbox layout, increased reverse gear shaft, four axle construction of traditional connected rear axle gearbox have been changed, become five by four of tradition, effectively utilized the space in the gearbox casing, each gear and axle are being changed under the little situation, more reasonable stress, structure are compact more.Thereby improved the transmission stability and the bearing capacity of agricultural transportation vehicle greatly, it is more reasonable that gear is distributed, and both can satisfy the farm work rate request, can satisfy the rate request of road transport again, improved the usability and the economic performance of vehicle.
Description of drawings
This accompanying drawing is the sectional stretch-out view of novel six grades of connected rear axle gearboxes.Among the figure, the 18th, connected rear axle gearbox case shell, A are the left wall of gear box casing, B is the right wall of gear box casing.1 is power input shaft, IV, V shelves slippage duplicate gear 3 and 4 are housed on the input shaft, realize respectively toward gear 4 and gear 17 engagements of moving to right, move to left gear 3 and gear 20 engagements, steel wire card 5 is assemblied in the groove of input shaft 1 right-hand member, gear 6 often meshes with gear 8, input shaft transmission of power to two spools 9, because of two 9 be splined shaft, shifting slide gear 7 is enclosed within on two 9, realize and gear 14 engagements toward moving left when shifting slide gear 7, produce the I shelves; Realize toward moving right and gear 12 engagements that when shifting slide gear 7 produce reverse gear, gear 13,15,19,23 is speed changing transmission gear; Two 9 left ends are II, III shelves duplicate gear 2 and 24, realize respectively toward gear 2 and gear 21 engagements of moving to right, and gear 24 and gear 22 engagements move to left.
