Double-planet-gear-set amphibious speed reducer, amphibious vehicle and control method thereof

Abstract

The invention discloses a double-planet-gear-set amphibious speed reducer. The double-planet-gear-set amphibious speed reducer comprises a power input shaft, a first sun wheel, a plurality of first planet wheels, a first gear ring, a first planet carrier, a clutch, a meshing sleeve, a land route output end and a water route output end, wherein the first sun wheel is coaxially and fixedly connectedwith the power input shaft, the first planet wheels are circumferentially arranged on the outer side of the first sun wheel, and the first planet wheels are in meshed transmission with the first sunwheel; the first gear ring is arranged concentric with the first sun wheel, and the first gear ring is in meshed transmission with the first planet wheels; the first planet carrier is rotationally connected with a wheel shaft of each first planet wheel in the circumferential direction, and a rotating column vertically extends from the center of the side, away from the power input shaft, of the first planet carrier; the clutch is coaxially and fixedly connected with the rotating column, and meshing teeth are arranged on the outer side of the clutch in the circumferential direction; the meshingsleeve is meshed with the clutch, synchronously rotates along with the clutch, and can move along the axis of the clutch. The invention further provides an amphibious vehicle which adopts the double-planet-gear-set amphibious speed reducer. The invention further provides a control method of the amphibious vehicle.

Description

Technical field [0001] The present invention relates to the technical field of reducers, and more specifically, the present invention relates to a dual planetary drainage land amphibious reducer, a waterway amphibious vehicle and a control method thereof. Background technique [0002] The reducer mainly refers to the reducer of the automobile, which can change the transmission ratio, expand the torque and speed of the driving wheel, and can also change the transmission direction and interrupt the power transmission. The amphibious vehicle is a special vehicle that combines the dual performance of a car and a boat. It can travel on land like a car and float on the water like a boat. At present, the power source of amphibious vehicles is generally the engine, and almost all of the transmission structure adopts two sets of power transmission structure. One set is output to the wheels by a transfer box, and the other is output to the propeller. Although the power between the waterway...

Problems solved by technology

At present, the power source of amphibious vehicles is generally the engine, and the transmission structure almost always uses two sets of power transmission structures, one set is output to the wheels by the transfer box, and the other is output to the propeller. Although the power between waterways and land can be realized Switching, but this power conversion makes the transmission mechanism relatively complicated, increases the weight of the vehicle, and even the power transmission after switching will be affected
