Abstract
The invention discloses a gear differential comprising left and right shells, a cross installed with four planetary gears and two half axle gears respectively engaged with the four planetary gears, wherein a power input gear is fixedly arranged on the right shell, the left shell and the right shell are combined to an entirety, and the cross is arranged in the shells; and lubricating oil holes are respectively formed in the left shell and the right shell. The gear differential is characterized in that fixing pieces are arranged on the four axle ends of the cross, the fixing pieces are arranged between the inner walls of the shells and the planetary gears, through holes corresponding to the cross are formed in the fixing pieces, and the four axle ends of the cross are penetrated through the through holes in the fixing pieces corresponding to the cross to be respectively clamped in the four axle holes in the shells. One fixing piece is respectively added at each of the four axle ends of the cross, and the cross can be completely fixed under the cooperation of the axle holes on the differential shells, thereby generating no loosening phenomenon, avoiding accidents and ensuring high safety.
Description
Technical field
The present invention relates to automotive drive, specifically, relate to gear differential.
Background technique
The power transmission of motor drives the driving gear of differential mechanism, directly drives differential casing, is delivered to planetary pinion again, drives the left and right half gear, and then drives wheel.When the vehicle straight-line travelling, three rotating speeds of the rotating speed of left and right half and differential casing rotating speed are identical.When turning, because the automobile stressing conditions changes, feedback is on left and right half, and then the original balance of destruction differential mechanism, and at this moment rotating speed is redistributed, and causes the inboard wheel rotating speed to reduce, and the outboard wheels rotating speed increases, and reaches balance again.Simultaneously, vehicle is finished turning work.Be provided with in the differential mechanism four planetary cross axles are installed, the housing of differential mechanism is provided with four axis holes for the fixed cross axle, and four axle heads of interior cross axle are stuck in four axis holes.
Four axis holes on the present stage employed differential casing are difficult to fully cross axle be fixed, and after long-term the use, becoming flexible can appear in cross axle, can be accidents caused when serious, and poor stability.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned defective, provides to be completely fixed cross axle, safe gear differential.
For addressing the above problem, the technical solution adopted in the present invention is:
Gear differential, comprise left shell, right shell body, four planetary cross axles are installed and are located at left shell respectively, on the sidewall of right shell body and respectively with two differential gears of four planetary pinions engagements, be set with power input gear on the right shell body, it is characterized in that: be equipped with the fixed plate that the bottom is provided with notch on four axle heads of described cross axle, fixed plate is located between inner walls and the planetary pinion, fixed plate is provided with the through hole corresponding with cross axle, four axle heads of cross axle all pass the through hole on the fixed plate corresponding with it, four axle heads of cross axle are stuck in four axis holes on the housing, the axis body of two differential gears is plugged on left shell respectively, in the mounting hole of right shell body, be provided with pad between differential gear and the inner walls.
As a kind of improvement:
Position near the differential mechanism support end on the sidewall of described left shell, right shell body is equipped with 4 oilholes.
Owing to adopted technique scheme, the present invention has set up a fixed plate respectively at four axle heads of cross axle, cooperates the axis hole on the differential casing, can be completely fixed cross axle, loosening phenomenon can not occur, avoids the generation of accident, and is safe; In addition, between two differential gears and inner walls, set up pad, avoided the direct friction of differential gear and inner walls, increase the service life.
The present invention will be further described below in conjunction with the drawings and specific embodiments.
