Problems solved by technology

[0003] The advantage of hydraulic transmission is to increase the flexibility of the transmission system, but the disadvantage is that the transmission efficiency is low; mechanical transmission has the advantages of high efficiency and mature technology, but it is difficult to realize gear switching without power interruption; hydraulic mechanical transmission is a dual-flow transmission method. Can better realize high-efficiency stepless speed change
[0004] The traditional single-mode transmission device is difficult to fully adapt to various working conditions, and it is difficult to achieve flexible start at the start, stepless speed regulation during operation, and high-efficiency transmission during transition

Abstract

The invention provides a multifunctional continuously variable transmission device comprising an output component, an input component, a hydraulic transmission assembly, a planet gear assembly, a clutch assembly and a brake assembly. The input component is connected with the hydraulic transmission assembly and the planet gear assembly. The planet gear assembly is connected with the output component through a gear shifting assembly. The input component and the hydraulic transmission assembly are connected to the planet gear assembly through the clutch assembly. The brake assembly and the clutchassembly provide the transmission ratio of continuous advancing or retreating between the input component and the output component. By combining regulation of the displacement ratio of the hydraulictransmission assembly and selective control over the clutch assembly and the brake assembly, the transmission manner of advancing or retreating between the input component and the output component isprovided. The transmission device can meet low-speed work and high-speed operation requirements, and continuous speed variation is achieved in the switching processes of all transmission manners.

Description

technical field [0001] The invention relates to the field of automatic transmission devices, in particular to a multifunctional continuously variable transmission device. Background technique [0002] The variable speed transmission device of a vehicle plays a decisive role in vehicle power, fuel economy and production efficiency. The continuously variable transmission has a good application prospect because it overcomes the power interruption in the vehicle transmission process. [0003] The advantage of hydraulic transmission is to increase the flexibility of the transmission system, but the disadvantage is that the transmission efficiency is low; mechanical transmission has the advantages of high efficiency and mature technology, but it is difficult to realize gear switching without power interruption; hydraulic mechanical transmission is a dual-flow transmission method. High-efficiency stepless transmission can be better realized. [0004] The traditional single-mode tr...
