Planetary gear type inter-axle differential for automobile

Abstract

Disclosed is a planetary gear type inter-axle differential for an automobile. A driving shaft is arranged inside a box body. One end of the driving shaft is installed inside a front driving power shaft, the other end of the driving shaft is installed inside a rear driving power shaft, and the front driving power shaft and the rear driving power shaft are installed inside the box body. A front driving gear is installed on the front driving power shaft. A planetary control support is installed on the driving shaft. An integration sun gear is integrated on the driving shaft. In addition, a front driving planetary gear supporting assembly and a rear driving planetary gear supporting assembly are the same in structure and installation mode. Front driving planetary gears are evenly installed on the planetary control support in the circumferential direction through the front driving planetary gear supporting assembly, and the front driving planetary gears are meshed with an inner ring gear of the front driving power shaft and the integration sun gear at the same time. According to the inter-axle differential, the planetary control support of a planetary gear transmission mechanism is adopted to drive the inter-axle differential through mechanical power, the problem of inconsistent non-proportional output of travelling wheels of front and rear driving axles is effectively solved, and the inter-axle differential is particularly suitable for a roller tractor four-wheel drive system, high in transmission efficiency, and easy and convenient to operate and facilitates driving.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery transmission, in particular to an inter-axle differential for a planetary gear type vehicle. Background technique [0002] Agricultural vehicles, especially general-purpose wheeled tractors, usually drive in the field. However, due to the soft texture of the field soil and low ground adhesion, in order to increase the driving capacity of the tractor, it is usually used to increase the diameter of the driving wheel, increase the tread depth of the tire, and use four-wheel drive etc. Among them, increasing the diameter of the wheel will weaken the steering ability of the front wheel. Therefore, in order to increase the driving force without reducing the steering ability of the tractor, the tractor wheel usually has a structure with small front wheels and large rear wheels; The wear and tear of the use of the tractor cannot effectively solve the problem of tractor driving ability; whe...

Problems solved by technology

Among them, increasing the diameter of the wheel will weaken the steering ability of the front wheel. Therefore, in order to increase the driving force without reducing the steering ability of the tractor, the tractor wheel usually has a structure with small front wheels and large rear wheels; It cannot effectively solve the problem of tractor driving ability; when using four-wheel drive, a special transmission mechanism must be designed to overcome the problem of different front wheel speeds due to different wheel sizes
