Abstract

The invention provides a variable-speed transmission device. The variable-speed transmission device comprises an input component, a hydraulic power transmission assembly, a mechanical transmission assembly, an output component and a clutch assembly; the input component and the hydraulic power transmission assembly are connected, the hydraulic power transmission assembly and the input component areconnected to the mechanical transmission assembly through the clutch assembly, and the mechanical transmission assembly and the output component are connected through the clutch assembly; and the clutch assembly provides the transmission ratio for continuous advancing or retreating between the input component and the output component. By adjusting the displacement ratio of the hydraulic power transmission assembly and selectively controlling joint of the clutch assembly, thus the transmission modes for advancing or retreating between the input component and the output component are provided and comprise static hydraulic transmission, hydraulic mechanical transmission and mechanical transmission. The variable-speed transmission device can be switched to be in three transmission modes, provides traveling and operation functions at the low gear position, and mainly provides the traveling function at the high gear position.

Description

technical field [0001] The invention relates to the field of transmissions, in particular to a variable speed transmission device. Background technique [0002] Agricultural vehicles are usually used in two different situations, field work and transport work, so the requirements for variable speed drives are slightly different. Hydraulic transmission has the characteristics of flexibility and is suitable for field operations with complex working conditions, but its efficiency is low; mechanical transmission has the characteristics of high efficiency, but it is difficult to realize stepless transmission without power interruption, and it is suitable for working conditions with good road conditions. [0003] Whether it is field work or transportation work, it is often necessary to output power to drive other devices, and walking and working in parallel are often carried out at low gears, and high gears are mostly suitable for walking purposes. [0004] The multiple gears of t...
