Planetary gear type inter-axle differential for four-wheel drive automobile

Abstract

Disclosed is a planetary gear type inter-axle differential for a four-wheel drive automobile. A driving shaft is arranged inside a box body. One end of the driving shaft is installed inside a gear type gear ring, and the other end of the driving shaft is installed inside a rear driving power shaft. A front driving power shaft is sleeved with a front driving gear which is meshed with the gear type gear ring. A control shaft is installed inside the box body. A control bevel gear is installed on the control shaft. A front driving gear ring and a front driving bevel gear ring which are installed on the driving shaft are symmetric about the control shaft, and a rear driving bevel gear ring and a rear driving gear ring which are installed on the driving shaft are symmetric about the control shaft. A front driving planetary gear supporting assembly and a rear driving planetary gear supporting assembly are the same in structure. A front driving integration sun gear and a rear driving integration sun wheel are integrated on the driving shaft. Front driving planetary gears are evenly installed on the gear type gear ring in the circumferential direction through the front driving planetary gear supporting assembly, and meshed with the front driving gear ring and the front driving integration sun gear at the same time. A planetary gear transmission mechanism is adopted as the inter-axle differential, the speed reduction function is achieved, the size of drive axles is effectively reduced, a ground clearance of a chassis of the automobile is improved, and the adhesive force is enhanced.

Description

technical field [0001] The invention relates to the technical field of automobile transmission, in particular to a planetary gear type inter-axle differential for four-wheel drive vehicles. Background technique [0002] At present, the four-wheel drive of vehicles mainly includes three types: full-time four-wheel drive, timely four-wheel drive and part-time four-wheel drive; among them, the full-time four-wheel drive mainly uses the Torsen inter-axle differential, and because the Torsen differential cannot The two ends of the connecting shaft are separated, and the vehicle with the differential can only be in the four-wheel drive state all the time. Although the passing performance of the vehicle is good, the fuel economy is poor. Widely used; while the timely four-wheel drive is controlled by computer, which can adjust the four-wheel drive mode in time according to the road surface conditions to realize the full-time four-wheel drive function, but the mechanism system is co...

[0002] At present, the four-wheel drive of vehicles mainly includes three types: full-time four-wheel drive, timely four-wheel drive and part-time four-wheel drive; among them, the full-time four-wheel drive mainly uses the Torsen inter-axle differential, and because the Torsen differential cannot The two ends of the connecting shaft are separated, and the vehicle with the differential can only be in the four-wheel drive state all the time. Although the passing performance of the vehicle is good, the fuel economy is poor. Widely used; while the timely four-wheel drive is controlled by computer, which can adjust the four-wheel drive mode in time according to the road surface conditions to realize the full-time four-wheel drive function, but the mechanism system is complex and the response is lagging, so it is widely used in mid-level off-road vehicles; Manual switching has been phased out
