Problems solved by technology

The gear shifting system with this structure needs to step on and release the clutch frequently, and the operation intensity is relatively high, which is likely to cause fatigue to the operator
[0004] In the traditional excavator hydraulic shifting system, the hydraulic torque converter, gearbox and transfer case assembly are split, and the entire shifting system is relatively bulky and takes up a lot of space

Abstract

The invention relates to a hydraulic variable-speed shifting system of an excavator. The system is characterized in that the system comprises a box, a hydraulic torque converter, an oil pump, a speed change mechanism and a transfer case assembly; the hydraulic torque converter, the oil pump, the speed change mechanism and the transfer case assembly are arranged in the box, the output end of the hydraulic torque converter is in transmission connection with the input end of the speed change mechanism, and the output end of the speed change mechanism is in transmission connection with the input end of the transfer case assembly. By means of the technical scheme, the hydraulic torque converter, the speed change mechanism, the oil pump and the transfer case assembly share one box, the hydraulic variable-speed shifting system is compact in structure and simple in transmission path, the system is better in transmission stability, and occupied space is saved.

Description

technical field [0001] The invention belongs to the technical field of excavators, and in particular relates to an excavator hydraulic shifting system. Background technique [0002] The gearbox is one of the important transmission components of the excavator. It is responsible for transmitting the speed and torque from the engine to the final drive system, changing the transmission ratio between the engine and the wheels, realizing the forward and reverse gear manipulation of the excavator, and can Realize cutting off the power transmitted to the traveling device when the engine is running, so as to meet the needs of the excavator's operation and driving, and facilitate the starting and parking safety of the engine. [0003] The traditional excavator hydraulic shifting system mainly adopts a manual shifting structure. During the shifting process, the clutch needs to be stepped on to cut off the power between the engine and the shifting system. After switching gears, the clut...
