Possibility, improve the overall security of recessed axle.
In order to more fully understand and implement, the utility model is described in detail below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the schematic diagram of prior art.
Fig. 2 is schematic diagram of the present utility model.
Fig. 3 is sectional view of the present utility model.
Embodiment
Refer to Fig. 2 and 3, a kind of recessed axle for trailer disclosed in the utility model, including two spindle noses 10, axis body 20
With connecting plate 30；One end of the spindle nose 10 is provided with the connecting portion 11 for being connected with the axis body 20；20 liang of the axis body
Bottom surface of the top surface at end respectively with the connecting portion 11 of the spindle nose 10 is fixed；The connecting plate 30 is arranged on the spindle nose 10 and institute
The side of axis body 20 is stated, side of the connecting plate 30 respectively with the spindle nose 10 and the axis body 20 is fixed.
The cross section of the connecting portion 11 of the spindle nose 10 is square, and plug welding hole 31 is provided with the connecting plate 30, described
It is provided with groove 32 on connecting plate 30, in the present embodiment, the groove 32 is dovetail groove.
The side of the axis body 20 is provided with boss 40, the shape of the boss 40 and the shape of groove 32 on the connecting plate 30
