Cross axle between universal-joint fork and the second universal-joint fork；Described cross axle includes that four sides offers screwed hole
Matrix, respectively with four sub-axles threadeding of screwed hole at described matrix four sides and be sheathed on described respectively
Four bearings on four sub-axles；Described matrix surface is provided with four reinforcements；In the middle of described four reinforcements
It is provided with oil nozzle.
Described first universal-joint fork is provided with relative two the first installing hole；Described second universal-joint fork is provided with phase
To two the second installing holes.
Described four bearings are respectively arranged in said two the first installing hole and two the second installing holes.
Described the first axle body is provided with the first ring flange away from one end of described first universal-joint fork.
Described the second axle body is provided with the second ring flange away from one end of described second universal-joint fork.
Advantage for present invention with effect is:
The truck drive shaft of the present invention, including: the first axle body, is connected to the first universal of the first axle body one end
Joint fork, the second axle body, it is connected to second universal-joint fork of the second axle body one end, is connected to the first universal-joint fork
And the cross axle that second between universal-joint fork；Cross axle include four sides offer screwed hole matrix, respectively with
Threaded four the sub-axles of screwed hole at matrix four sides and four axles being sheathed on respectively on four sub-axles
Hold；Matrix surface is provided with four reinforcements；Article four, it is provided with oil nozzle in the middle of reinforcement；Cross axle uses split type
Structure, production cost is low, and precision is high, and cross axle surface is provided with reinforcement simultaneously, adds the strong of cross axle
Degree；Thus improve the reliability of truck drive shaft, the processing cost reducing truck drive shaft is low, promotes
The precision of truck drive shaft.
Accompanying drawing explanation
The invention will be further described below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the truck drive shaft of the present invention；
Fig. 2 is the decomposing schematic representation of the truck drive shaft of the present invention；
Fig. 3 is the structural representation of the cross axle of the truck drive shaft of the present invention.
In figure: the first axle body 1, the second axle body 2, cross axle the 10, first ring flange the 11, first universal joint
Pitch 12, second ring flange the 21, second universal-joint fork 22, matrix 101, sub-axle 102, bearing 103, add
Strong muscle 104, oil nozzle the 105, first installing hole the 121, second installing hole 221.
Detailed description of the invention
As shown in Figure 1 to Figure 3, the present invention provides a kind of truck drive shaft, including: the first axle body 1, company
It is connected to first universal-joint fork 12 of the first axle body 1 one end, the second axle body 2, is connected to the second axle body 2 one end
The second universal-joint fork 22, the cross axle that is connected between the first universal-joint fork 12 and the second universal-joint fork 22
