Planetary gear type convex block slip limiting inter-axle differential for automobile

Abstract

Disclosed is a planetary gear type convex block slip limiting 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 gear type gear ring, and the other end of the driving shaft is installed inside a rear driving power shaft. The gear type gear ring is installed inside the box body. A front driving power shaft is sleeved with a front driving gear. A slip limiting fixing frame is installed on the driving shaft. A front driving integration sun gear and a rear driving integration sun gear are integrated on the driving shaft. Front driving planetary gears are evenly distributed on the slip limiting fixing frame in the circumferential direction through a front driving planetary gear supporting assembly. Rear driving planetary gears are evenly distributed on the rear driving power shaft in the circumferential direction through a rear driving planetary gear supporting assembly. A slip limiting convex block is arranged between the slip limiting fixing frame and the box body and installed between a left fixed convex block and a right fixed convex block. The left fixed convex block and the right fixed convex block reduce the rotating speed of the slip limiting fixing frame through the slip limiting convex block so as to achieve the slip limiting effect. Due to the fact that planetary gear mechanisms in a front row and a rear row have the equal structural parameters, the problem of inconsistent non-proportional output of front travelling wheels and rear travelling wheels is effectively solved.

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 lug limited-slip 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 depth of the tire tread and four-wheel drive. Among them, increasing the diameter of the wheel will weaken the steering ability of the front wheel, so in order to increase the driving force without reducing the steering ability of the tractor, the usual structure of the tractor is that the front wheel is small and the rear wheel is large; increase the depth of the tire pattern With the wear of the tires, the drive capacity of the tractor cann...

[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 depth of the tire tread and four-wheel drive. Among them, increasing the diameter of the wheel will weaken the steering ability of the front wheel, so in order to increase the driving force without reducing the steering ability of the tractor, the usual structure of the tractor is that the front wheel is small and the rear wheel is large; increase the depth of the tire pattern With the use of the tires, the driving capacity of the tractor cannot be increased in essence; if the four-wheel drive is adopted, a special transmission mechanism must be designed to overcome the problem of different speeds of the front wheels due to the different sizes of the wheels

At the same time, because tractors are prone to driving slippage when working in the field, in order to improve the passability of the tractor, the tractor is usually equipped with a forced differential lock. When the driving wheel slips, the differential is forced to be locked manually. Reduced work efficiency and increased system operation complexity
