Abstract
The utility model discloses a through type intermediate axle main speed reducer comprising an intermediate axle main speed reducer housing, an inter-axle differential mechanism, a through axle, a triple gear, a cylindrical gear, a driving bevel gear connected with the cylindrical gear, a driven bevel gear, an inter-wheel differential mechanism and an output shaft, wherein the driving bevel gear is engaged with the driven bevel gear, the driven bevel gear is arranged on the left wheel input end of the inter-wheel differential mechanism, 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 mechanism; one output end of the inter-axle differential mechanism is connected with the output shaft, and the other output end of the inter-axle differential mechanism is connected with the cylindrical gear by the triple gear; the inter-axle differential mechanism is arranged on the power output side of the intermediate axle main speed reducer housing. The through type intermediate axle main speed reducer can adapt to special types of vehicles, and can improve the performance of the transmission shaft.
Description
Technical field
The utility model relates to automobile drive axle jackshaft main reduction gear arrangement structure, is specifically related to a kind of through jackshaft main reduction gear.
Technical background
The jackshaft main gearbox assembly that uses on the automobile at present generally adopts power intake and the interaxle differential arrangement form at output semiaxis homonymy, and interaxle differential is positioned at the power input side of jackshaft main reduction gear.Said structure causes front end (power intake) excessive height of jackshaft main reduction 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 utility model content
The purpose of the utility model is to above-mentioned technical matters, and a kind of through jackshaft main reduction 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 through jackshaft main reduction gear of the utility model institute design-calculated, it comprise jackshaft bevel housing, interaxle differential, thru shaft, triple gear, cylindrical wheel, with cylindrical wheel bonded assembly drive bevel gear, driven wheel of differential, inter-wheel differential, wherein; Said drive bevel gear and driven wheel of differential engagement; Said driven wheel of differential is arranged at the revolver limit input end of inter-wheel differential, and it is characterized in that: it also comprises output shaft, and an end of said thru shaft connects power input shaft; The other end of thru shaft connects interaxle differential; A mouth of said interaxle differential connects output shaft, and another mouth of interaxle differential connects cylindrical wheel through triple gear, and said interaxle differential is arranged at the takeoff output side of jackshaft bevel housing.
The beneficial effect of the utility model: said structure makes the power intake height of jackshaft main reduction gear obviously reduce, and can adapt to some special vehicle.In addition,, make jackshaft main reduction gear power intake compresses in length, help connecting the outer drive shafts lengthening of power intake, improve the performance of transmission shaft because interaxle differential is arranged in the takeoff output 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---interaxle differential, 3---thru shaft, 4---cylindrical wheel, 5---drive bevel gear, 6---inter-wheel differential, 6.1---the revolver mouth, 7 of inter-wheel differential---driven wheel of differential, 8---jackshaft bevel housing, 8.1---takeoff output side, 9---triple gear, 10---power input shaft.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify:
Through jackshaft main reduction gear as shown in Figure 2; It comprises jackshaft bevel housing 8, interaxle differential 2, thru shaft 3, triple gear 9, cylindrical wheel 4, with cylindrical wheel 4 bonded assembly drive bevel gear 5, driven wheel of differential 7, inter-wheel differential 6; Wherein, drive bevel gear 5 and driven wheel of differential 7 engagements, driven wheel of differential 7 is arranged at the revolver limit input end 6.1 of inter-wheel differential 6; It also comprises output shaft 1; One end of thru shaft 3 connects power input shaft 10, and the other end of thru shaft 3 connects interaxle differential 2, and a mouth of interaxle differential 2 connects output shaft 1; Another mouth of interaxle differential 2 connects cylindrical wheel 4 through triple gear 9, and interaxle differential 2 is arranged at the takeoff output side 8.1 of jackshaft bevel housing 8.
In the technique scheme, an end of said interaxle differential 2 outputs power to back axle, and interaxle differential 2 other ends connect cylindrical wheel 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.
The content that this specification sheets is not done to describe in detail belongs to this area professional and technical personnel's known prior art.
