According to statistics, the vast majority of car owners' awareness of car brands is limited to "groundless", and their knowledge of cars is also very small, so let's introduce how to disassemble the car differential housing for everyone today!

According to statistics, the vast majority of car owners' awareness of car brands is limited to "groundless", and their knowledge of cars is also very small, so let's introduce how to disassemble the car differential housing for everyone today!

The automobile differential housing can make the left and right (or front and rear) driving wheels complete the organization of rotation through different speed ratios. It is mainly composed of upper and lower drive shaft gears, two large planetary gears and a gear carrier. The function is to make the front and rear wheels flip through different speed ratios when the car is turning or driving on uneven ground, that is, to ensure that the driving wheels on both sides perform pure rolling fitness exercises. The differential housing shell is a device to adjust the speed difference between the upper and lower wheels. In four-wheel drive, in order to be able to push the four wheels, all the wheels must be connected to each other. If the mechanical equipment of the four wheels is connected together, the car should not rotate at the same rate in the s-turn. The speed of the car's s-turn movement is basically consistent. At this time, a central differential housing needs to be added to adjust the speed difference of the front wheels.

1. disassembly and assembly

Note: appropriate sleeve specifications should be selected, the general sleeve specifications are 17, 18, 22, 24, model specifications of hexagonal sleeve specifications, disassembly and assembly should pay attention to the diagonal disassembly of screws, pay attention to the use of tools and cleanliness.

1. Remove the positive hyperbolic equation gear connection boss and oil seal seat, bevel gear with seat bearing, and remove the positive hyperbolic equation gear;

2. Remove the end cover of the driven hyperbolic equation gear bearing, remove the total range of the driven hyperbolic equation gear, and unscrew the differential housing shell screw to dissolve the differential housing.

2. installation

Note: The installation sequence is for this disassembly and then for this disassembly, and the second disassembly is installed first. The screw torque of the differential housing is 77.4NM. Note that the screws should be tightened diagonally during installation.

1. Clean up all parts;

2. Assembling the differential housing, installing the driven hyperbolic equation gear, installing the driven gear bearing end cover and adjusting the preload of the driven gear rolling bearing;

3. Install the positive hyperbolic equation gear and oil seal seat on the bevel gear with seat bearing and adjust the positive gear rolling bearing pre-tightening force through the sealing pad;

4. Assemble the positive hyperbolic equation gear, adjust the meshing gap and meshing of the main and driven bevel gears according to the adjustment of the positive bevel gear with seat bearing, the middle gasket of the automobile differential housing and the nuts on both sides of the rotating driven bevel gear Scratches.

The above is about the introduction of the differential housing to share with you. I hope that with this article, you will have a better understanding of the differential housing project.
