Description

A kind of steering drive axle

Technical field

The utility model relates to automobile-used drive axle field, relates to a kind of steering drive axle that drives function that is used for playing on construction machinery and equipment or the farm machinery in particular.

Background technology

Along with the continuous development of society, generally can only adopt manual work before the people, all can replace at present with corresponding machinery, such as when crops are gathered in, people can adopt reaper to replace the harvesting of reaping hook, and have higher harvesting efficiency.

At present; Engineering or farm machinery are in order to have preferable power support, and it need be set to four wheel drive usually, thus; What the propons of this project or farm machinery then need be realized wheel simultaneously turns to and drives two kinds of functions; Be steering drive axle, it comprises axle housing, core wheel, driving device and steering hardware, and this axle housing and chassis are fixedly linked and extending axially and have a hollow structure along core wheel; This core wheel lays respectively at axle housing left end and right-hand member.This driving device then mainly plays drive axle; It comprises parts such as deceleration assembly and universal transmission mechanism, and this deceleration assembly specifically comprises parts such as main reduction gear and diff again, and this main reduction gear is located at axle housing opening middle inside; Mainly be to play to slow down to increase the effect of square; Be about to the automobile rotary torque convert into axletree to moment of torsion, this diff then mainly be because automobile when turning, about two wheel rotor speeds different; So this diff plays the allotment velocity contrast, thereby reduce tire and ground-surface slip; This universal transmission mechanism then is used to transfer torque to core wheel, thereby makes core wheel to rotate; This steering hardware then is provided with in order to realize turning to function.

But above-mentioned existing steering drive axle often has following defective:

One, its axle housing is set to the left-right symmetric shape usually; The power take-off shaft of this main reduction gear and driving engine all is positioned at the center of symmetry place thus; So will be not easy to the installation of other parts such as change speed gear box on the chassis, so the length of the whole machinery that can extend influences the miniaturization of whole machinery;

Two, its axle housing generally is through being connected with car chassis with the axle sleeve of vehicle bridge integrally casting moulding, and this axle sleeve is to the fixed distance of axle center, thereby makes the spacing between vehicle bridge and the chassis to adjust.

In view of this, the inventor has this case to produce to the above-mentioned defective in-depth study of existing steering drive axle then.

The utility model content

The purpose of the utility model is to provide a kind of steering drive axle, to solve the problem that turns to drive axle to hinder whole mechanical miniaturization and can't adjust spacing between vehicle bridge and the chassis in the prior art.

In order to reach above-mentioned purpose, the solution of the utility model is:

A kind of steering drive axle comprises axle housing, core wheel, driving device and steering hardware, and this axle housing and chassis are fixedly linked and extend axially and have hollow structure along core wheel, and this axle housing also is formed with opening; This core wheel is arranged on the two ends of axle housing rotationally; This driving device comprises that deceleration assembly that is contained in the axle housing and the universal transmission mechanism that is contained in the steering hardware, this deceleration assembly are installed in opening part and also pass this axle housing and supply to link to each other with mechanical semiaxis transmission; This steering hardware is arranged between axle housing and the core wheel and the turning to of control core wheel; Wherein, this opening departs from the center with axle housing, and integrally casting forms bearing on this axle housing, and this bearing also is connected with the spider that confession links to each other with the chassis.

Further, this universal transmission mechanism is the double cruciform shaft seat mechanism, and its deflection angle all can reach 35 °

Further, this steering hardware also comprises left steering joint and right steering joint, also is provided with the tie rod assembly that is used to transmit steering angle between this left steering joint and the right steering joint.

After adopting said structure, a kind of steering drive axle that the utility model relates to, it has following beneficial effect at least:

One, because this opening deviates from the center of this axle housing; Promptly should the deceleration assembly and mechanical semiaxis between transmission deviate from the center of whole propons; Can be by direct mount, so the utlity model has the effect of compact conformation thereby can make such as parts such as change speed gear boxs;

Two, because this bearing is to be fixedly linked with the chassis through spider, and this spider can and bearing between carry out position adjustment, thereby make that the spacing between this vehicle bridge and the chassis can be adjusted, so the utlity model has effect applied widely.
