front axle loader

[Ludo1996]

Good morning to all,
I write to you why I have to make a project for an examination of machines, precisely concerning a front axle of a shovel.
the most critical condition is that of break-out, that is when the shovel is on the ground and must raise material. in this condition on the axle weighs about 1.8 times the operating weight of the vehicle, while the shooting force (forces to the pneumatic) is equal to the weight itself. inside the axle, at the end, we have two epicyclical gearboxes and in between a differential (in attachment the figure). I would have used only these loads and I would have schematized everything as a beam, but my professor says that I must also consider the action of bearings (from what I have understood the weight is discharged on the axle through also the bearings and in particular the central "nase" of the axle affected by a force that pushes it upwards) and the crown of the epicycloidal which is supportive to the axle case.
As a result, I just can't understand the loads that (flenching and torque movements) that weigh on the structure.
I thank everyone who can help me in advance.

external forces agents on the external carpentry due to wheel/frame reaction is one thing. what happens inside the gearboxes is another thing and obviously there are actions and reactions inside if he eroded couple to win and rotate the wheels under load.

the worst condition is when your loader shovel is traveling at its maximum speed, with the bucket loaded at max a short distance from the ground and takes holes and bumps of the road.
the contents of the axle consider it zavorra,
for your verafca, consider the axle and box of the final reducer, of course with all connections (vitations and bearings)
Hi.

ciao @ludo1996. is it possible to have the text of your project/built exercise of machines?
I only ask for my curiosity.
