Embodiment Construction

[0020] like figure 1 As shown, a loader transmission mechanism includes a three-element hydraulic torque converter, a high-speed clutch assembly and a low-speed clutch assembly;

[0021] like figure 2 As shown, the three-element hydraulic torque converter includes a cover wheel, a turbine wheel, a guide wheel, and a pump wheel;

[0022] The output shaft of the three-element hydraulic torque converter is fixedly connected with the first low-gear gear in the low-gear clutch assembly through electron beam welding to directly transmit torque; the first low-gear gear is fixedly connected with the low-gear outer hub through electron beam welding, Torque is transmitted directly; the low-grade outer hub and the low-grade separator transmit torque through the spline pair; the low-grade separator and the low-grade friction plate transmit torque through friction; the low-grade friction plate and the low-grade inner hub transmit torque through the spline pair; the low-grade inner hub an...

Abstract

The invention relates to a transmission mechanism of a loading machine. A high-gear clutch assembly and a low-gear clutch assembly are added in a loading machine system, the problems of a high fault rate and low efficiency of a transmission mechanism adopted by a conventional loading machine are solved, the model selection range of a hydraulic torque converter is broadened, and the loading machine is converted from hydrodynamic transmission to mechanical transmission under the working condition of a high speed ratio. The working efficiency is improved, the energy consumption is reduced, and the purposes of high efficiency and energy saving are achieved.

Description

technical field [0001] The invention relates to a transmission mechanism, which is suitable for loaders with different configurations of high, medium and low, and can also replace the transmission mechanism of high-end loaders and even realize the upgrading of transmission mechanisms of other loaders. Background technique [0002] The existing loader transmission mechanism includes a twin-turbine hydraulic torque converter and a planetary power shift gearbox structure (two front and one rear). The twin-turbo torque converter has a high failure rate and low overall efficiency. In the actual operation of the loader, the low-speed heavy-load and high-speed light-load conditions are frequently switched, and the large overrunning clutch used in the twin-turbo torque converter in the planetary power shift transmission is subject to a large impact during the change of working conditions, and the failure rate high. Large overrunning clutches are inconvenient to overhaul and expens...
