Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further described with reference to the following embodiments.
As shown in fig. 1-4, for the utility model provides a split type knuckle that AGV steering drive axle used, its characterized in that includes: a knuckle body 1 and a journal 5,
a hydraulic cylinder bracket 2 is fixedly arranged in the middle of one outer side surface of the steering knuckle body 1, the hydraulic cylinder brackets 2 comprise two symmetrically arranged hydraulic cylinder brackets 2, two symmetrical first through holes 3 are formed in the two hydraulic cylinder brackets 2, the two first through holes 3 are used for fixedly connecting a hydraulic cylinder through bolts, a plurality of second threaded holes 7 are formed in the surface of the steering knuckle body 1, which is in contact with a shaft neck 5,
