Abstract

The invention provides a continuously variable transmission device for a hydraulic machine and solves the problem that the transmission system in the prior art is complicated in structure. The devicecomprises an engine and a hydraulic continuously variable transmission connected to the engine. The hydraulic continuously variable transmission comprises a quantifying motor and a variable pump. Theshaft head of the variable pump is connected to a transmission shaft through a connecting sleeve. A gear ring capable of rotating the transmission shaft is coaxially mounted on the transmission shaft.A planet carrier capable of rotating around the transmission shaft is also coaxially mounted on the transmission shaft. A plurality of planet wheel axles are uniformly mounted on the planet carrier.Double planet wheels are arranged on each planet wheel axle. A coaxial hollow transmission shaft is successively arranged from inside to outside out of the transmission shaft in a sleeving mode. The hollow transmission shaft is fixed to the planet carrier. An output shaft is also parallelly arranged on the transmission shaft. A clutch shell is also fixedly mounted on the output shaft. A hollow shaft is also arranged on the periphery of the output shaft in a sleeving mode. A reverse gear wheel axle parallel to the transmission shaft and the output shaft is also arranged between the transmissionshaft and the output shaft. The transmission system provided by the invention is simple in structure and is of very good practicality.

Description

technical field [0001] The invention relates to the technical field of transmission devices, in particular to a hydraulic-mechanical continuously variable transmission device applied to tractors. Background technique [0002] At present, most domestic tractors are equipped with mechanical gear shifting, and a small amount are powered gear shifting. The transmission ratio of each gear in these gear shifting methods is discontinuous, so it is impossible to choose a suitable transmission ratio according to the vehicle load, and the fuel consumption is still high. [0003] Hydraulic mechanical stepless transmission tractor, the working principle is to use hydraulic and mechanical transmission to transmit power respectively, its transmission efficiency is high, the transmission ratio can be adjusted steplessly, the power transmission is not interrupted during the adjustment process, and the engine can be controlled to always work at the highest efficiency work under conditions. ...
