ZL25 Axle

Suitable for construction machinery, wheel loaders

Two-stage decelerating structure is adopted for the drive axle.

Spiral bevel gears with great load-carrying capacity and high efficiency are adopted for main drive.

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

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

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

Suitable for a ZL25 loader.

The stress axle is at the cease of the electrical power transmission system, and its essential factors are: (1) transmitting the engine torque from the traditional transmission pc to the stress wheel with the aid of the use of the critical reducer, differential, 1/2 of shaft, etc., to minimize tempo and extend torque; (2) Change the transmission route of torque thru the bevel tools pair of the vital reducer; (3) The differential realizes the differential of the wheels on each and every factors to make positive that the internal and outer wheels steer at exceptional speeds; (4) The bearing and torque transmission sides are realized with the aid of the bridge shell and wheels.
The stress axle design ought to meet the following vital requirements:
1. The imperative reduce fee ratio chosen have to make positive that the car has the splendid electricity and fuel economy.
2. The installed dimension desire to be small, and the fundamental floor clearance want to be ensured. It frequently refers to the measurement of the quintessential reducer as small as possible.
3. Gears and unique transmission factors work easily and have low noise.
4. High transmission effectivity beneath particularly a range speeds and loads.
5. Under the circumstance of making sure adequate electrical energy and stiffness, the mass ought to be small, in particular the unsprung mass have to be as small as doable to enhance the smoothness of the car.
6. Coordinate with the motion of the suspension statistics mechanism, and for the practise axle, it have to in addition coordinate with the motion of the education mechanism.
7. Simple structure, real processing technology, reachable manufacturing, convenient to disassemble and adjust.
The strength axle is divided into two categories: non-disconnected range and disconnect type.
It is now now now not disconnected
When the electrical energy wheels are non-independent suspension, a non-disconnected axle have to be selected. The non-disconnected stress axle is in addition referred to as the fundamental pressure axle, and its 1/2 shaft casing and indispensable reducer shell are rigidly related to the axle shell and a monolithic beam, so that the half of of of axle and electrical energy wheel on each and every facets swing in relation to every and each other, and are linked to the physique by using elastic elements. It consists of a pressure axle housing, a predominant reducer, a differential and a 1/2 of of shaft.
Disconnected
The stress axle adopts unbiased suspension, that is, the most essential reducer shell is constant on the frame, and the 1/2 axle and stress wheel on each and every facets can have relative motion in the transverse plane relative to the auto body, which is referred to as a disconnected stress axle.
To mate with the independent suspension, the most vital reducer housing is consistent to the physique (or body), the electrical energy axle housing is segmented and related through the usage of hinges, or there are no one of a kind elements of the stress axle housing barring the important reducer housing. In order to meet the wishes of unbiased up and down runout of the stress wheel, the sections of the half-shaft between the differential and the wheel are related through the use of way of everyday joints.
