Background technique
Differential mechanism is widely used in various vehicles, automobile differential left and right (or forward and backward) driving wheel can be made to realize with
The mechanism of different rotating speeds rotation.Mainly by left and right half gear, planetary gear and differential casing, planetary gear shaft, gasket etc.
Composition.Function be when automobile turning travel or on uneven road surface when driving, roll left and right wheels with different rotating speeds, that is, guarantee
Two sides driving wheel makees PURE ROLLING.Differential mechanism is to adjust the rotational speed difference of left and right wheels and device.
Summary of the invention
The utility model aim is to provide a kind of novel split type differential mechanism, reliability compact with axial arrangement
The features such as high, easy to process and assembly.Using split type differential design, its shell structure feature is simplified, compares monoblock type
Poor shell blank is easier to cast or forge, and simplifies blank manufacturing process, and overcome piece differential cage body because cutter is rigid
Deficiency causes to process the disadvantages of interior surface precision is difficult to ensure.In addition, avoiding traditional truck differential mechanism from planet hole location
It sets to the shell scheme divided, it is easier to guarantee the position precision of bevel planet gear after assembly.
In order to solve the above technical problems, the present invention is achieved by the following technical scheme:
A kind of detachable automobile driver differential assembly, which is characterized in that differential casing is by a left shell and one
A right shell body assembly is constituted, and further includes two planetary gears, two axle shaft gears, two planet gear pads, two half axle gears
Gasket, a planetary gear shaft, a snap ring and multiple rivets are taken turns, left shell and right shell body pass through multiple rivet interlacements, wherein
One axle shaft gear support is mounted in left shell, and the bearing of another axle shaft gear is mounted in right shell body, first half axle gear
Between wheel and left shell and second is respectively arranged with an axle shaft gear gasket, two planet teeth between axle shaft gear and right shell body
Wheel is located in right shell body by planetary gear shaft, and planetary gear is engaged with axle shaft gear, and planet axis upper end is realized by snap ring
Axially position on right shell body, two planetary gears with and the contact position of right shell body have a planet gear pad suit respectively
On planetary gear shaft (7).
Further technical solution includes:
The left shell subtracts bull gear with master and becomes one.
The lower end of planetary gear shaft is equipped with the shaft shoulder, upper end is equipped with annular groove, and one end when assembly equipped with annular groove passes through the right side
After shell, snap ring, which is caught in annular groove, realizes axially position.
The cooperation position design of the diameter of axle and right shell body of planetary gear shaft has spiral oil-way.
Right shell body one end is integrated with the driving gear for vehicle mileage metering.
Compared with prior art the beneficial effects of the present invention are:
By adopting the above-described technical solution, the utility model is compact-sized, axial dimension is smaller, total convenient for speed changer
At arrangement；The blank and finished product anufacturability of differential casing are good, it is easier to which processing and assembly are easily guaranteed that the essence of product
Degree requires.In addition, using forging pinion steel, structural strength is substantially improved, more holds after left shell and main reducing gear bull gear are integrated
Easily realize lightweight.
