Abstract
The utility model discloses a tractor differential which comprises a left housing and a right housing, a cross equipped with four planetary gears, and two half axle gears meshed with the four planetary gears. A power input gear is arranged on the right housing, the left housing and the right housing are combined into a whole, and the cross is arranged in the housings; and lubricant holes are formed on the left housing and the right housing respectively. The differential is characterized in that fixed plates are arranged at the four shaft ends of the cross and are arranged between the inner walls of the housings and the planetary gears; through-holes corresponding to the cross are formed on the fixed plates; and four shaft ends of the cross penetrate through-holes corresponding to the cross and formed on the fixed plate, and then clamped into the four shaft holes on the housing. A fixed plate is additionally arranged on each of four shaft ends of the cross, so that according to the matching of the four shaft ends with the shaft holes on the differential housing, the cross can be completely fixed, thereby avoiding looseness, preventing incidence of accidents, and achieving high safety.
Description
Technical field
The utility model relates to a kind of automotive drive, specifically, relates to a kind of tractor differential mechanism.
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 driving wheel.The rotating speed sum of left and right half equals two times of differential casing rotating speed.When the vehicle straight-line travelling, above-mentioned three rotating speeds 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 that are used for fixing cross axle, and four axle heads of interior cross axle are stuck in four axis holes.Find in the practice that only depend on four axis holes on the differential casing to be difficult to fully cross axle be fixed, after long-term the use, becoming flexible can appear in cross axle, can be accidents caused when serious, poor stability.
Summary of the invention
The technical problem that will solve of the present utility model is to overcome above-mentioned defective, and a kind of cross axle, safe tractor differential mechanism of being completely fixed is provided.
For addressing the above problem, the technological scheme that the utility model adopted is:
A kind of tractor differential mechanism, comprise left shell, right shell body, four planetary cross axles are installed and be located on the sidewall of left shell, right shell body respectively and respectively with two differential gears of four planetary pinions engagements, be set with power input gear on the right shell body, left shell combines as a whole with right shell body, cross axle is located in the housing; Be respectively equipped with oilhole on left shell and the right shell body, it is characterized in that: be equipped with fixed plate 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, are stuck in four axis holes on the housing.
As improvement of the technical scheme:
Described fixed plate bottom is provided with notch.
The axis body of described two differential gears is plugged on respectively in the mounting hole of left shell, right shell body, is provided with pad between differential gear and the inner walls.
Position near the differential mechanism support end on the sidewall of described left shell, right shell body is equipped with described oilhole, and respectively is provided with 4.
Owing to adopted technique scheme, the utility model has been 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 utility model is described in further detail below in conjunction with the drawings and specific embodiments.
