Differential and transfer case for 4 wheel driven amphibious vehicle

Abstract

The invention discloses a differential and transfer case for a 4 wheel driven amphibious vehicle, which includes a case body, wherein a power input shaft is arranged at the front part of the case body along the front-rear horizontal direction; the middle part of the power input shaft is mounted on the case body through a bearing; the front part of the power input shaft forwards extends out of the case body; a first duplicate gear is fixedly sleeved at the rear end of the power input shaft in the case body; a front gear of the first duplicate gear is engaged with a first transmission gear; the first transmission gear is fixedly sleeved at the front part of a transmission shaft; the first transmission shaft is rotatably mounted in the case body along the front-rear horizontal direction; a second transmission gear is fixedly sleeved at the rear part of the first transmission shaft; the second transmission gear is engaged with a rear gear of a second duplicate gear; the second duplicate gear is rotatably sleeved at the front part of a middle and rear power output shaft; and the middle and rear power output shaft and the power input shaft are coaxially arranged. The differential and transfer case for the 4 wheel driven amphibious vehicle has compact structure, stable performance, high transmission efficiency and low energy consumption, is safe and reliable, and can effectively improve the trafficability of the vehicles.

Description

technical field [0001] The invention relates to a differential transfer case for a four-wheel-drive amphibious vehicle. Background technique [0002] The differential transfer case of an existing amphibious vehicle usually adopts the transfer case of an automobile. Due to the lack of a power output shaft directly driving the water jet propeller, it is necessary to set up another set of transmission system to drag the water jet propeller. This leads to a more complex design structure of the vehicle, a higher failure rate, and lower transmission efficiency, which in turn leads to higher fuel consumption, lower passing capacity, and poor adaptability of the vehicle. Contents of the invention [0003] The object of the present invention is to provide a differential transfer case for a four-wheel drive amphibious vehicle that has compact structure, stable performance, safety and reliability, high transmission efficiency, low energy consumption, and can effectively improve the p...
