Abstract
The utility model discloses an intermediate axle main speed reducer which comprises an intermediate axle main speed reducer casing, an inter-axle differential, a through shaft, a triple-gear block, a cylindrical gear, a driving bevel gear connected with the cylindrical gear, a driven bevel gear and an inter-wheel differential, wherein the driving bevel gear is meshed with the driven bevel gear; the intermediate axle main speed reducer also comprises an output shaft and an idle gear; the driven bevel gear is arranged on the input end at the right wheel side of the inter-wheel differential; one end of the through shaft is connected with a power input shaft, and the other end of the through shaft is connected with the inter-axle differential; one output end of the inter-axle differential is connected with the output shaft, and the other output end of the inter-axle differential is connected with the idle gear through the triple-gear block; the idle gear is connected with the cylindrical gear; and the inter-axle differential is arranged on the power output side of the intermediate axle main speed reducer casing. The intermediate axle main speed reducer is applicable to certain special vehicles, and meanwhile, the performance of a transmission shaft is improved.
Description
Technical field
The utility model relates to automobile drive axle jackshaft main reducing gear layout, is specifically related to a kind of jackshaft main reducing gear.
Technical background
The through jackshaft main reducing gear of using on the automobile at present, its effect are in giving the power distribution that motor transmits, back axle, and the differential action in will realizing, between back axle.Traditional through jackshaft main reducing gear generally adopts power intake and the mean differential setting type at output semiaxis homonymy, and mean differential is positioned at the power input side of jackshaft main reducing gear.Said structure causes front end (power intake) excessive height of jackshaft main reducing gear, and on some special vehicle, this structure is unfavorable for the car load layout, and has caused the power intake transmission shaft too short, has influenced the performance of transmission shaft.
The model utility content
The purpose of the utility model is to above-mentioned technical problem, and a kind of jackshaft main reducing gear is provided, and at the bottom of its power intake height, the car load that is beneficial to specific special vehicle is arranged.
For realizing this purpose, the jackshaft main reducing gear that the utility model designed, it comprises jackshaft bevel housing, mean differential, perforation axle, triple gear, cylindrical gears, the drive bevel gear that is connected with cylindrical gears, driven wheel of differential, inter-wheel differential; Wherein, Said drive bevel gear and driven wheel of differential engagement, it is characterized in that: it also comprises output shaft and idle pulley, said driven wheel of differential is arranged at wheel limit, the right side input end of inter-wheel differential; A said end that connects axle connects power input shaft; The other end that connects axle connects mean differential, and an output terminal of said mean differential connects output shaft, and another output terminal of mean differential connects idle pulley through triple gear; Said idle pulley connects cylindrical gears, and said mean differential is arranged at the power outlet side of jackshaft bevel housing.
The beneficial effect of the utility model: said structure makes the power intake height of jackshaft main reducing gear obviously reduce, and can adapt to some special vehicle.In addition,, make jackshaft main reducing gear power intake compresses in length, help connecting the outer drive shafts lengthening of power intake, improve the performance of transmission shaft because mean differential is arranged in the power outlet side (being the rear end) of jackshaft bevel housing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein, 1---output shaft, 2---mean differential, 3---perforation axle, 4---cylindrical gears, 5---drive bevel gear, 6---inter-wheel differential, 6.1---right side wheel output terminal, 7---driven wheel of differential, 8---jackshaft bevel housing, 8.1---power outlet side, 9---triple gear, 10---power input shaft, the 11---idle pulleys of inter-wheel differential.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify:
Jackshaft main reducing gear as shown in Figure 1; It comprises jackshaft bevel housing 8, mean differential 2, connects axle 3, triple gear 9, cylindrical gears 4, the drive bevel gear 5 that is connected with cylindrical gears 4, driven wheel of differential 7, inter-wheel differential 6; Drive bevel gear 5 and driven wheel of differential 7 engagements, it also comprises output shaft 1 and idle pulley 11, driven wheel of differential 7 is arranged at wheel limit, the right side input end 6.1 of inter-wheel differential 6; An end that connects axle 3 connects power input shaft 10; The other end that connects axle 3 connects mean differential 2, and an output terminal of mean differential 2 connects output shaft 1, and another output terminal of mean differential 2 connects idle pulley 11 through triple gear 9; Idle pulley 11 connects cylindrical gears 4, and mean differential 2 is arranged at the power outlet side 8.1 of jackshaft bevel housing 8.
In the technique scheme, an end of said mean differential 2 outputs power to back axle, and mean differential 2 the other ends connect cylindrical gears 4 through triple gear 9, output power to jackshaft.
Said structure can reduce the height of jackshaft power intake, improves the outer drive shafts performance.Above-mentioned idle pulley 11 has been adjusted the sense of rotation of jackshaft output terminal, has satisfied the requirement that car load goes.
The content that this specification is not done to describe in detail belongs to related domain professional and technical personnel's known prior art.
