Planetary transmission reduction gearbox and special equipment

Abstract

The invention relates to a planetary transmission reduction gearbox and special equipment, and belongs to the technical field of special equipment. The planetary transmission reduction gearbox comprises a box body, an input gear, a planetary gear mechanism, an output gear and a wet clutch, wherein the input gear, the planetary gear mechanism, the output gear and the wet clutch are arranged in the box body. The wet clutch is connected between the input gear and the planetary gear mechanism. The planetary transmission reduction gearbox further comprises a hydraulic system, the hydraulic system comprises an oil way connected with the wet clutch, a clutch oil pump and a control valve, the clutch oil pump and the control valve are connected to the oil way, and the control valve is provided with a first working position and a second working position which enable the wet clutch to be combined and separated respectively. A first power take-off gear is arranged in the box body, and the clutch oil pump is in transmission connection with the first power take-off gear. By adopting the wet clutch, the operation difficulty of a driver is reduced, the operation time is shortened, and the driving efficiency is improved. Meanwhile, as long as the input gear rotates, the clutch oil pump can be driven to work, combination or separation of the wet clutch is achieved, an independent external force mechanism is not needed, and energy consumption can be reduced.

Description

technical field [0001] The invention relates to a planetary transmission reduction box and special equipment, and belongs to the technical field of amphibious special equipment. Background technique [0002] At present, the reduction box of the amphibious transport vehicle is usually a fixed-axis structure, which is large in size and heavy in weight, and it is difficult to achieve the lightweight requirements of the amphibious transport vehicle. In this regard, the Chinese invention patent application with the application publication number CN112407220A discloses an amphibious vehicle hybrid transmission and its amphibious vehicle. The transmission includes a propeller driving mechanism, a wheel driving mechanism, a gear mechanism and a transmission assembly. The propeller driving mechanism is used for The power output of the amphibious vehicle (that is, special equipment) in the water, including the normally open clutch (that is, the pump-jet propulsion clutch) and the wate...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a planetary transmission reduction box to solve the problem that in the prior art, the clutch for switching between land and water modes needs additional power to be controlled, resulting in increased energy consumption and high requirements for speed difference, resulting in difficult operation and difficult operation. The problem of long time and low driving efficiency; the purpose of the present invention is also to provide a special equipment to solve the problem that the existing special equipment needs extra power to control the clutch of switching between the land and water modes, which leads to increased energy consumption and the comparison of the requirements for the speed difference High operation difficulty, long operation time and low driving efficiency
