Connecting device for transmitting power

Abstract

The invention discloses a connecting device for transmitting power. The connecting device comprises a motor assembly, a hydraulic transmission assembly, and a connecting assembly arranged between themotor assembly and the hydraulic transmission assembly. The connecting assembly comprises a power transmission shaft, a power connection disc and a torque converter which are sequentially arranged. Alarge end plate of the power transmission shaft is connected with the power output end of the motor assembly through an output flange, and the tip of the small end of the power transmission shaft is fixedly connected with the power connection disc through a connecting piece. The connecting assembly arranged between the motor assembly and the hydraulic transmission assembly is compact in structureand reasonable in layout, all parts of the connecting assembly are easy to manufacture and low in machining cost, mounting and dismounting are convenient, the reliability requirements of radial and axial connection when the motor assembly and the hydraulic transmission assembly realize power transmitting through the connecting assembly are met, and the power transmitting effect is good.

Description

technical field [0001] The invention relates to the technical field of power forklifts, in particular to a connection device for power transmission. Background technique [0002] At present, the power transmission scheme of electric forklifts generally adopts the direct connection between the drive motor and the drive axle or gearbox to realize the vehicle power transmission to realize the functions of the vehicle. With the continuous innovation of the development scheme of the electric forklift power transmission system, the power transmission system of the original internal combustion vehicle The hydraulic transmission is also used as a technical solution on electric forklifts, and then the advantages of internal combustion forklift hydraulic transmissions are brought into play on electric forklifts. [0003] The original internal combustion forklift hydraulic gearbox realizes axial and radial installation and positioning and power transmission through the engine flywheel,...

AI Technical Summary

Problems solved by technology

[0003] The original internal combustion forklift hydraulic gearbox realizes axial and radial installation and positioning and power transmission through the engine flywheel, flywheel housing and other components. After years of technology accumulation and application, although there is a relatively complete power transmission scheme, many The structure is complicated, and installation and disassembly are inconvenient. In addition, the power transmission system commonly used in the prior art is extremely unstable during use, especially the power system composed of the motor assembly and the hydraulic transmission assembly. The commonly used connecting devices lead to The effect of power transmission is poor and unreliable, which cannot meet the needs of the market
