ZL30 Axle

Suitable for construction machinery, wheel loaders.

Two-stage decelerating structure is adopted for drive axle.

Spiral bevel gears with great bearing capacity anhigh efficiency are adopted for main drive.

The wheel is planetary decelerating structure.

The main reducer is equipped with the common bevel-gear differential mechanism with simpe structure and flexible differential function.

Cast steel with adequate rigidity serves as material for axle housing.

The brake in clamp-disc braking mode has great braking monent.

Suitable for ZL30 loader and 14-18T road roller.

The stress axle is at the end of the electrical energy transmission system, and its indispensable elements are: (1) transmitting the engine torque from the conventional transmission computer to the stress wheel by using the vital reducer, differential, half of shaft, etc., to decrease pace and lengthen torque; (2) Change the transmission direction of torque through the bevel equipment pair of the essential reducer; (3) The differential realizes the differential of the wheels on every components to make certain that the inner and outer wheels steer at special speeds; (4) The bearing and torque transmission facets are realized via the bridge shell and wheels.
The pressure axle sketch ought to meet the following imperative requirements:
1. The fundamental cut price ratio chosen have to make certain that the automobile has the incredible strength and gas economy.
2. The established dimension want to be small, and the vital flooring clearance need to be ensured. It often refers to the size of the quintessential reducer as small as possible.
3. Gears and distinctive transmission elements work effortlessly and have low noise.
4. High transmission effectivity below pretty a variety speeds and loads.
5. Under the circumstance of making certain ample electricity and stiffness, the mass ought to be small, in specific the unsprung mass have to be as small as potential to decorate the smoothness of the car.
6. Coordinate with the action of the suspension data mechanism, and for the guidance axle, it have to moreover coordinate with the movement of the preparation mechanism.
7. Simple structure, genuine processing technology, accessible manufacturing, easy to disassemble and adjust.
The energy axle is divided into two categories: non-disconnected variety and disconnect type.
It is now now not disconnected
When the electricity wheels are non-independent suspension, a non-disconnected axle have to be selected. The non-disconnected pressure axle is moreover referred to as the essential strain axle, and its half shaft casing and crucial reducer shell are rigidly associated to the axle shell and a monolithic beam, so that the half of of axle and electricity wheel on every sides swing in relation to each and every other, and are linked to the physique via elastic elements. It consists of a strain axle housing, a primary reducer, a differential and a half of of shaft.
Disconnected
The strain axle adopts independent suspension, that is, the most important reducer shell is consistent on the frame, and the half axle and pressure wheel on every sides can have relative action in the transverse aircraft relative to the auto body, which is referred to as a disconnected pressure axle.
To mate with the unbiased suspension, the most important reducer housing is steady to the physique (or body), the electricity axle housing is segmented and associated by using hinges, or there are no special factors of the pressure axle housing barring the main reducer housing. In order to meet the needs of independent up and down runout of the strain wheel, the sections of the half-shaft between the differential and the wheel are associated by using way of ordinary joints.
