Abstract
The utility model discloses a spider differential gear for farming vehicles and is characterized in that a left casing and a right casing of a differential gear are combined as integrity, a power input gear is arranged on the integral casing, four planetary gears on a spider, four shaft ends of the spider are respectively arranged by four axle holes on the left and right casings of the differential gear, two axle shaft gears are arranged on both sides of the casing of the differential gear and respectively engaged with four planetary gears. The side wall of the left casing of the spider and/or the right casing of the differential gear nearby the supporting end of the differential gear is provided with a plurality of lubricating holes. A shaft line at the position of the lubrication holes and nearby a rotation shaft can draw the lubricant in the casing of the differential gear under the centrifugal force and maintain the effect of lubrication, overcoming current differential gears' disadvantages of bad lubrication and loss of lubricant.
Description
Technical field
The utility model relates to a kind of cross axle differential mechanism.
Background technique
The power of motor directly drives planetary wheel carrier (differential carrier) through the driving gear of speed changer drive differential mechanism, 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 sides semiaxis equals two times of differential carrier 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 the semiaxis of the left and right sides, 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 state of equilibrium again.Simultaneously, vehicle is finished turning action.
Find in practice, because the cross axle differential mechanism is lubricated, be that the oilhole that is positioned at the differential carrier junction plane is lubricated, its shortcoming is the center of this position away from the differential mechanism rotating shaft, because action of centrifugal force, the lubricant oil in the differential casing is thrown out of housing, rather than enter housing, this lubricating system has greatly reduced the working life of differential mechanism, and noise is very big, can be accidents caused when serious.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of Agricultural automotive vehicle cross axle differential mechanism with good lubrication structure.
For achieving the above object, the technical solution of the utility model is: Agricultural automotive vehicle cross axle differential mechanism, comprise and being combined as a whole and as the differential left of planetary wheel carrier, right shell body, a fixedly connected power input gear on the housing, four planetary pinions are installed on the cross axle respectively, four axle heads of cross axle are fixed by four corresponding axis holes on the left and right sides housing of differential mechanism, two differential gears also mesh with four planetary pinions respectively in the differential casing both sides respectively, on the sidewall of described differential left housing and/or differential right casing body, the nearer position of supported end near differential mechanism is provided with some oilholes.
Owing to adopt technique scheme, Agricultural automotive vehicle cross axle differential mechanism, comprise and being combined as a whole and as the differential left of planetary wheel carrier, right shell body, a fixedly connected power input gear on the housing, four planetary pinions are installed on the cross axle respectively, four axle heads of cross axle are fixed by four corresponding axis holes on the left and right sides housing of differential mechanism, two differential gears also mesh with four planetary pinions respectively in the differential casing both sides respectively, on the sidewall of described differential left housing and/or differential right casing body, the nearer position of supported end near differential mechanism is provided with some oilholes; The position of oilhole, can be drawn onto lubricant oil in the housing of differential mechanism owing to action of centrifugal force near the axis of rotating shaft, and keeps lubrication, has overcome former differential mechanism and has been difficult for lubricated and the easy shortcoming of losing of lubricant oil.
