To the problems referred to above, people have developed the steer drive front-axle that uses to agricultural machine, and it can realize that on the one hand propons drives, and can also play the effect that turns to simultaneously.Existing steer drive front-axle; Comprise axle housing, driving device, mobile devices and steering hardware as the one of which; This axle housing is for carrying main body; This driving device is then given mobile devices with transmission of power, and this steering hardware then is used for turning to of driving process, and and mobile devices between be provided with universal transmission mechanism.Though playing, said structure let farm implements that the f-w-d function is arranged; But; Above-mentioned universal transmission mechanism often only can be realized the universal transmission on the horizontal surface, and agricultural machine in the process of moving, and it can not be in the plane always; Make that thus above-mentioned traditional steer drive front-axle then has defective poor for applicability when difference in height occurring; In addition, because axle housing generally is to link to each other through bolt with steering hardware, it also has the defective of structural strength difference.
In view of this, the inventor has this case to produce to the above-mentioned defective in-depth study that turns to drive front axle in the existing agricultural machine then.
The utility model content
The purpose of the utility model is to provide a kind of agricultural machine steer drive front-axle, turns to the problem of drive front axle in transmission effect difference when highly gap being arranged in the existing agricultural machine to solve.
In order to reach above-mentioned purpose, the solution of the utility model is:
A kind of agricultural machine steer drive front-axle; Comprise axle housing, driving device, mobile devices and steering hardware; This driving device is arranged in the axle housing and to the mobile devices transferring power; This steering hardware has left steering joint and the right steering joint that is positioned at the end, and the middle part main gear of axle housing links to each other with the output shaft of agricultural machine gearbox through transmission shaft, and two ends then link to each other with the right steering joint with the left steering joint respectively; This driving device links to each other with agricultural machine gearbox transmission and links to each other with mobile devices through a universal transmission mechanism; Wherein, This steering hardware also comprises and turns to oil cylinder, left oil cylinder seat, right oil cylinder seat, left steering bar and right steering bar; This left side oil cylinder seat and right oil cylinder seat branch are arranged on the both sides that turn to oil cylinder; This left steering bar and right steering bar one end are all accepted the thrust that turns to oil cylinder through a sphero-joint, and the other end is then linked to each other with the right steering joint by the left steering joint respectively.
Further, the endosphere that saves of this left steering joint and right steering all with axle housing one welding fabrication.
Further, this agricultural machine steer drive front-axle also is provided with left drg and the right drg that all plays brake action.
Further, this agricultural machine steer drive front-axle also is provided with the hub reduction assembly.
Further, this universal transmission mechanism is that double cruciform shaft structure and deflection angle reach 35 °.
After adopting said structure; A kind of agricultural machine steer drive front-axle that the utility model relates to; It is through at left steering bar and right steering bar and turn to also to be provided with between the oil cylinder and play the sphero-joint that transmits thrust; So make whole steer drive front-axle when facing the transmission of difference in height, also can play the self-align effect, thereby guarantee that whole vehicle bridge remains on stable mode of operation always; Simultaneously through letting endosphere that left steering joint and right steering save, thereby can let whole steer drive front-axle continuous more firm with respect to conventional bolt with the axle housing welding fabrication.
Description of drawings
The structural representation of Fig. 1 a kind of agricultural machine steer drive front-axle for the utility model relates to, wherein mobile devices partly adopt and analyse and observe;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the amplification view of A-A line among Fig. 2.
Among the figure:
The specific embodiment
In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.
Extremely shown in Figure 3 like Fig. 1, a kind of agricultural machine steer drive front-axle 100 that the utility model relates to, it comprises axle housing 1, driving device 2, mobile devices 3 and steering hardware 4, this axle housing 1 is as the carrying main body of whole steer drive front-axle 100.
This driving device 2 is arranged in the axle housing 1 and to mobile devices 3 transferring power; This steering hardware 4 has the left steering joint 41 and right steering joint 42 that is positioned at the end; The middle part main gear of axle housing 1 links to each other with the output shaft of agricultural machine gearbox through transmission shaft; Right ends then links to each other with right steering joint 42 with left steering joint 41 respectively, and this driving device 2 links to each other with agricultural machine gearbox transmission and links to each other with mobile devices 3 through a universal transmission mechanism.
