Embodiment Construction

[0020] The structure of the present invention is described in detail below in conjunction with accompanying drawing:

[0021] Such as Figure 1A , Figure 1B As shown, the through-type drive axle is composed of axle housing 1, wheel side reducer 2, hyperboloid bevel gear through-type main reducer 3, brake 4, through-shaft 5 and wheels, etc., hyperboloid bevel gear through-type main reducer 3 is installed on the axle housing 1.

[0022] combine Figure 2A and Figure 2B , the hyperboloid bevel gear through-type main reducer 3 consists of an inter-axial differential lock, a rear housing 13, an input shaft 17, an input flange 15, a flange locking end cover 16, an oil seal 18, a bearing 19, and a through-shaft bevel gear 20. Active bevel gear 24, cross shaft 22, planetary gear 21, differential cover 23, spline sleeve 25, spiral ring bearing seat 26, through shaft 30, active hyperboloid bevel gear 28, passive hyperboloid bevel gear 38, wheel Inter-differential and inter-wheel ...

Abstract

The invention provides a through drive axle with a hyperboloid bevel gear and relates to the technical field of vehicle transmission. A through main speed reducer of the through drive axle adopts a through main speed reducer with the hyperboloid bevel gear. The through drive axle comprises an inter-axle differential lock, an input shaft, an input flange, a spline housing, a through drive axle bevel gear, an active bevel gear, a spider, a planet gear, a through shaft, an active hyperboloid bevel gear, a passive hyperboloid bevel gear, an inter-gear differential and an inter-gear differential lock. The through drive axle uses the characteristics that axial leads of a gear wheel and a pinion of a hyperboloid bevel gear pair are vertical but not intersected and have a certain offset. The through shaft passes through the active hyperboloid bevel gear to coaxially rotate and passes through from the upside or the downside of a half axle so that the transmission mode of the through drive axle is simplified, the manufacturing cost is reduced, the transmission efficiency is improved, the noise is effectively reduced, the problems of poor cooling and lubricating and the like are solved, and light weight of a drive axle assembly is realized. Therefore, the through drive axle is suitable for popularization and application.

Description

technical field [0001] The invention relates to a multi-connected drive axle used in multi-axle (three-axle and more than three-axle) heavy-duty vehicles. . Background technique [0002] At present, in the design and manufacture of domestic multi-axle heavy-duty vehicles, in order to simplify the structure, simplify the arrangement of the transmission shaft, make the components common and facilitate the formation of series products, through-type drive axles are often used. The drive shafts of the two drive axles are connected in series, and the drive shaft passes through the drive axle that is closer to the transfer case and leads to the other drive axle. In this arrangement, the drive shaft must pass through the drive axle. This type of drive axle is called a through drive axle. The through-type drive axle is composed of through-type main reducer, axle housing, wheel reducer, wheels and so on. At present, the structure of the through-type main reducer commonly used in th...
