Abstract
The invention discloses a four-wheel cross driving type differential mechanism. The four-wheel cross driving type differential mechanism comprises a differential mechanism shell, wherein a planetary gear rack is installed in the differential mechanism shell in a rotary mode through a bearing, the whole planetary gear rack is fixed to a driven gear, the driven gear is led out through an inner planetary gear, an outer planetary gear, a front inner half shaft, a front outer haft shaft, a rear inner half shaft and a rear outer haft shaft, the inner planetary gear and the outer planetary gear are arranged in the planetary gear rack, the front inner half shaft and the rear inner half shaft are connected to the inner planetary gear, and the front outer half shaft and the rear outer haft shaft are connected to the outer planetary gear. According to the four-wheel cross driving type differential mechanism, an X type cross driving mode is adopted, wheels at the front cross position and the rear cross position are used for driving at the same time, and as a result, an automobile can be stable enough on any road surfaces where the automobile can run, and slipping and deviation between the front wheels and the rear wheels are avoided; in addition, the four-wheel cross driving type differential mechanism is small in size and capable of saving energy resources and reducing unnecessary energy consumption.
Description
Technical field
The present invention relates to differential mechanism field, concrete is a kind of 4 wheel driven cross-drive differential mechanism.
Background technique
According to the principle of automobile running, the vehicle wheel rotational speed sum on diagonal equates, so can cross-drive.And the mode that existing common four-wheel driven car adopts front-wheel and trailing wheel separately to drive, cause common four-wheel driven car not travel with too high speed, otherwise easily occur trackslipping and shift phenomenon, more easily occur too jolting on the road surface of situation complexity, drive the problems such as unstable, travelling comfort and Security that impact is travelled.
Summary of the invention
The present invention, for solving deficiency of the prior art, provides a kind of 4 wheel driven cross-drive differential mechanism.
Technological scheme of the present invention:
4 wheel driven cross-drive differential mechanism, comprise differential casing, it is characterized in that: in described differential casing, be rotatablely equipped with planet braces by bearing, planet braces entirety is fixed on driven gear, and described follower is by the inside and outside planetary pinion in planet braces and be connected to front inside and outside semiaxis and the rear inside and outside semiaxis derivation on inside and outside planetary pinion;
Described front inside and outside semiaxis is derived by be in transmission connection driving cog in front right, the outer driving cog of front left of front interior transfer tooth, front outer transfer tooth respectively;
Described rear inside and outside semiaxis is derived by be in transmission connection driving cog in rear left, the outer driving cog of rear right of rear interior transfer tooth, rear outer transfer tooth respectively.
Described 4 wheel driven cross-drive differential mechanism, is characterized in that: described driven gear drives whole differential mechanism by driving gear external connection power source.
Described 4 wheel driven cross-drive differential mechanism, is characterized in that: described inner planet gear drives forward and backward inner shaft to drive one group of front and back wheels that is positioned at crossover location; Exterior epicyclic gear drives forward and backward outer semiaxis to drive another group to be positioned at the front and back wheels of crossover location.
Advantage of the present invention:
The mode that the present invention adopts X-type cross to drive, the wheel being positioned on forward and backward crossover location is driven simultaneously, can make automobile have enough stability on any road surface that can exercise, between front and back wheel, there will not be and trackslip and shift phenomenon, and volume of the present invention is little, save the energy, reduced unnecessary energy loss.
