Description

technical field [0001] The invention belongs to the field of deceleration equipment for amphibious wheeled vehicles, and relates to a wheel-side deceleration structure with a diaphragm clutch. Background technique [0002] In the field of amphibious wheeled vehicle equipment, if the wheel-side reducer meets the actual operating conditions of light-load high-speed and heavy-load low-speed, it can give full play to the power of the prime mover; if it solves the problem of high-speed input, it can be matched with high-density high-speed motors, In order to reduce the weight of the whole machine; at the same time, the gearbox is integrated with the structure of the lifting system, which can simplify the lifting system; according to actual use, the more compact the structure of the wheel reducer, the better, and the lighter the weight, the better. [0003] Most of the reducers of the current amphibious wheeled vehicles do not have the gear function, and cannot meet the dual worki...

AI Technical Summary

Problems solved by technology

[0003] Most of the reducers of the current amphibious wheeled vehicles do not have the gear function, and cannot meet the dual working conditions of light load high speed and heavy load low speed. The transmission ratio is single, and the output speed is usually changed by motor frequency conversion. At the same time, ordinary wheel-side reducers do not meet the high-speed input requirements, and cannot be used with high-power-density high-speed motors. Most of them have a single parallel shaft structure, and there is no integrated equipment to match the structure of the lifting system, resulting in a complicated lifting system. , using bulky box, no compact structure

The wheel reducers in other fields are mostly used in crawler vehicles, and they are multi-stage accumulative planetary transmission structures, which do not have the ability to change gears and cooperate with lifting
