Detailed Description

The invention is further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.

As shown in fig. 1-3, the amphibious vehicle hub comprises a wheel 1, wherein the wheel 1 comprises a wheel disc 11, a wheel rim 12 and a central cylinder 13, the central cylinder 13 is coaxial with the wheel rim 12, the wheel disc 11 is connected between the wheel rim 12 and the central cylinder 13, and the wheel 1 is integrally formed by casting. The spoke 11 includes a plurality of spokes, has 5 spokes in this embodiment, and 5 spokes are the circumference on wheel 1 and evenly set up. The spoke 11 is provided with a plurality of cavities 14 which are uniformly distributed on the circumference. The central cylinder 13 is internally provided with a sliding cavity 15, the impeller disc 2 is arranged in the sliding cavity 15 in a sliding mode, and the impeller disc 2 can move along the axial direction of the sliding cavity 15 so as to adjust the distance between the impeller disc 2 and the wheel 1. The outer side of the impeller disc 2 is fixed with a transmission shaft bolt of a vehicle. The impeller disc 2 is provided with 5 groups of blades 21 on the side facing the wheel 1, and the blades 21 correspond to the cavities 14. A telescopic power device 3 is arranged between the impeller disc 2 and the wheel 1, and the telescopic power device 3 is used for pushing the impeller disc 2 to approach or be far away from the wheel 1. When the telescopic power device 3 drives the impeller disc 2 to be closest to the wheel 1, the blades 21 on the impeller disc 2 are correspondingly accommodated in the cavity 14, and the land traveling state of the vehicle is at this time. When the telescopic power device 3 drives the impeller disc 2 to be farthest away from the wheel 1, the blades 21 on the impeller disc 2 are pulled out from the cavity 14 of the wheel 1 to stir water, and at the moment, the water is in a vehicle underwater advancing state.

Specifically, a plurality of sliding grooves 16 are formed in the inner wall of the sliding cavity 15, a connecting shaft 22 is welded or integrally formed in the center of the impeller disc 2, a shaft key 23 in sliding fit with the sliding grooves 16 is machined in the upper outer wall of the connecting shaft 22, the telescopic power device 3 is mounted between the sliding cavity 15 and the connecting shaft 22 and driven by the telescopic power device 3, the sliding grooves 16 and the shaft key 23 are in sliding fit to serve as limiting positions, and the impeller disc 2 and the wheel 1 are close to and away from each other (namely, the blades 21 are accommodated and separated from each other).

Specifically, the telescopic power device 3 is a through shaft type lead screw servo motor, wherein the through shaft type lead screw servo motor adopts a waterproof motor. The connecting shaft 22 is a hollow shaft, the hollow shaft of the connecting shaft 22 is an installation cavity, the through shaft type lead screw servo motor is fixedly installed in the installation cavity through a bolt, and a lead screw of the through shaft type lead screw servo motor is rotatably connected with the bottom of the sliding cavity 15. The through-shaft type lead screw servo motor drives the lead screw on the through-shaft type lead screw servo motor to rotate, so that the wheels 1 and the impeller discs 2 are close to and far away from each other. Wherein the screw rod can be connected with the inner wall of the sliding cavity 15 through a plane bearing and also can be connected through a ball head.

In particular, each set of said blades 21 comprises 2-5 blades.
