Description
Technical field
The present invention relates to straight bevel gear differential art field more particularly to a kind of straight bevel gear differential assembly and
Its processing method.
Background technique
Open differential be usually by two or four planetary gear, planetary wheel carrier (integral differential mechanism and a word axis or
Left and right differential carrier and cross axle), the parts composition such as two axle shaft gears and spherical pad, semiaxis flat shim, such as 1 institute of attached drawing
Show；The power of engine enters differential mechanism through transmission shaft, directly drives planetary wheel carrier, then be meshed therewith by planetary gear drive
Axle shaft gear, two axle shaft gears drive left and right two semiaxis to match therewith again, respectively drive left and right wheel, differential mechanism
Design requirement meet: (left half axle revolving speed)+(right axle shaft revolving speed)=2 (planetary wheel carrier revolving speed)；It is left and right when automobile straight trip
Wheel is equal with the revolving speed of planetary wheel carrier three, is in equilibrium state, and in automobile turning, three's equilibrium state is destroyed, and is led
Inboard wheel revolving speed is caused to reduce, outboard wheels revolving speed increases, when cornering, since outboard wheels have sliding the phenomenon that dragging, inside vehicle
Wheel the phenomenon that trackslipping, two driving wheels will generate the opposite additional force of both direction at this time, due to " minimum stream power ",
Necessarily cause the revolving speed of two sidecar wheels different, to destroy the equilibrium relation of three, and passes through semiaxis reflection to axle shaft gear
On, it forces planetary gear to generate rotation, makes inside semiaxis spin down, outside semiaxis faster rotational speed, to realize two sidecar wheels
The difference of revolving speed.
Now common straight-tooth bevel differential in the market at work, still turn, differential mechanism by either automobile straight trip
In two axle shaft gears, all always in rotation, and between axle shaft gear gasket and shell, axle shaft gear, always from time to time
In relative rotation, frictional force generation is at this moment just had between gasket and shell, axle shaft gear, because differential gear material is low
Carbon alloy steel will result in the abrasion of gasket and shell over time；When automobile turning, the planetary gear in differential mechanism is removed
Revolution is outer, can also generate rotation, and planet gear pad also can generate abrasion because of sliding friction at this time；When automobile is poor in road conditions
Mining area or moment when accelerating, slowing down, differential gear under external force, moment by axial force at the increase of geometric multiple,
When gear rotates, frictional force be increased dramatically, and shell and gasket abrasion are even more serious, there is also gasket and gear faying face sometimes
Between burn to death, be bonded, make to continue relative rotation between gasket and shell, the abrasion between more aggravation gasket and shell, when planet, half axle gear
When the gasket of wheel is worn to a certain extent, under external force, each gear has edge to be axially disengaging tap web to the gear being meshed
Trend so that gear cannot ensure to engage near cyclotomy, and contact patch is made to be biased to tooth top, the rigid phase of tooth top is to most
Difference is easy for chip off-falling and broken teeth, inside differential assembly, regardless of which part chip off-falling, all entire differential mechanism can be made to be led
Even property damage.
Therefore, a kind of straight bevel gear differential assembly is now urgently designed to ask to solve the abrasion of components in use
Topic.
Summary of the invention
The purpose of the present invention is to provide a kind of straight bevel gear differential assembly and its processing methods, reduce each part
Between wear-resistant degree great disparity status, it is relatively quiet for improving relative rotation or rotation trend state intrinsic between former each contact surface
The advantages of only motionless state, prevents fretting wear, makes the rolling friction for the sliding friction bearing for having relative rotation solves existing
Common straight-tooth bevel differential in the market at work, two axle shaft gears in differential mechanism, all always in rotation, gasket
Frictional force generation is just had between shell, axle shaft gear, because differential gear material is low-carbon alloy steel and through carburizing and quenching
Processing, over time, the problem of will result in the abrasion of gasket and shell.
