FIELD: engineering industry. ^ SUBSTANCE: invention refers to transport engineering industry, and namely to through drive axles. Through hypoid final drive consists of reduction gear case (1), driving flange (2) installed on drive shaft (3) whereon there pressed is cylindrical drive pinion (4). In case (1), on tapered bearings (5) and (6) there located is drive hypoid pinion (7) provided with a shank. In case (1) there located is a centre differential containing carriers (10) and (11). Carrier (10) is installed on tapered bearing (12) located in the case (1) and that is an integral part of driven pinion (13) engaged with cylindrical drive pinion (4). Carrier (11) is installed on radial thrust bearing (14) located in case (1). Axle shaft pinion (17) of centre differential is connected by means of splines to through shaft (19) of main reverse gear drive the horizontal axis of which is located below axis of cross-axle differential (20). Axle shaft pinion (18) is installed on splines of pinion-shaft (24) coaxially relative to shaft (19) of main reverse gear drive on bearings (25) and (26) located in case (1) and carrier (10) of centre differential respectively. Pinion-shaft (24) is engaged with driven pinion (27) fixed on the splined end of shank of drive hypoid pinion (7). ^ EFFECT: improving durability of cardan shaft and hypoid gear. ^ 3 dwg |
