Abstract
The utility model belongs to the field of machinery, particularly discloses an improved transmission which comprises a main box of double intermediate shafts and an auxiliary box of double auxiliary shafts; and a shaft gear 1 on one shaft of the main box is meshed with an intermediate shaft transmission gear on the double intermediate shafts on both sides, a shaft gear 2 on the other shaft of the main box is meshed with all gears on the double intermediate shafts on both sides, a conveying gear on the output shaft of the auxiliary box is meshed with the transmission gear on the double auxiliary shafts on both sides, and a high-low gear synchronizer is arranged in the auxiliary box. The improved transmission has the advantages of simple structure, reasonable, economical and practical layout, light weight, large torque and reasonable distribution of overall speed ratio, and facilitates the full saving of energy and the improvement of efficiency.
Description
(1) technical field
The utility model belongs to mechanical field, particularly a kind of improved type speed changer.
(2) background technique
At present, the gearbox that domestic heavy motor truck uses has adopted two jack shafts mostly, the odd-side synchronizer, and it realizes certain speed ratio by the number of nibbling that axle cogs.Because present speed changer production is essentially several fixed modes, they carry out different combinations according to different models to gear, thereby form certain speed ratio, but, a kind of model of existing gearbox, a kind of speed ratio, overgear and the speed changer that directly keeps off all have certain defective to cause speed ratio all less, and when improving the overgear, can directly influence low speed starting difficulty, run at high speed and directly influence when solving low speed starting difficulty, the reasonable distribution of wanting to reach whole speed ratio then is difficult to.
(3) summary of the invention
The utility model provides a kind of simple in structure, economical and practical improved type speed changer in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of improved type speed changer, comprise the main tank of two jack shafts and the odd-side of a two-pack axle, jack shaft driving gear engagement on a shaftgear on one of the main tank and the two jack shafts of its both sides, two shaftgears on two of the main tanks are meshed with the gear that respectively keeps off on two jack shafts of its both sides, driving gear on the two-pack axle of the conveyance gear on the odd-side output shaft and its both sides is meshed, and is provided with the high to low gear synchronizer in the odd-side.
Scheme of the present utility model is:
The number of teeth of a described shaftgear is 28, and the number of teeth of the jack shaft driving gear relative with it is 35; The number of teeth of two four retaining gears is 26, and the number of teeth of the jack shaft four retaining gears relative with it is 43; The number of teeth of output reduction gear is 44 in the odd-side, and the number of teeth of the output drive gear relative with it is 13, and the number of teeth of passive transmitting gear is 36.
The utility model improves the number of gears of its inside on the basis of existing speed changer, makes the low speed starting easily, and it is fast to run at high speed, and the advantage of two kinds of speed changers unites two into one, and realizes the reasonable distribution of whole speed ratio.
The utility model is simple in structure, and is rationally distributed economical and practical, light weight, and moment of torsion is big, and whole Speed Ratio Distribution is reasonable, helps abundant energy saving, raises the efficiency.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, one of 1 main tank, 2 jack shaft driving gears, two of 3 main tanks, 4 odd-side output shafts, 5 high to low gear synchronizers, 6 one shaftgears, 7 two four retaining gears, 8 jack shafts, four retaining gears, 9 output reduction gear, 10 output drive gears, 11 passive transmitting gears.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises the main tank of two jack shafts and the odd-side of a two-pack axle, shaftgear 6 on one 1 of the main tank meshes with jack shaft driving gear 2 on two jack shafts of its both sides, two shaftgears on two 3 of the main tanks are meshed with the gear that respectively keeps off on two jack shafts of its both sides, driving gear on the two-pack axle of the conveyance gear on the odd-side output shaft 4 and its both sides is meshed, be provided with high to low gear synchronizer 5 in the odd-side, the number of teeth of a described shaftgear 6 is 28, and the number of teeth of the jack shaft driving gear 2 relative with it is 35; The number of teeth of two four retaining gears 7 is 26, and the number of teeth of the jack shaft four retaining gears 8 relative with it is 43; The number of teeth of output reduction gear 9 is 44 in the odd-side, and the number of teeth of the output drive gear 10 relative with it is 13, and the number of teeth of passive transmitting gear 11 is 36.
The existing speed changer that rated speed is identical and the speed ratio of speed changer of the present utility model compare:
As can be seen from the above table, climbing retaining speed ratio of the present utility model obviously improves compared to existing speed changer, and top gear relatively obviously improves, and the Speed Ratio Distribution of other each retainings is comparatively reasonable.
