Abstract

The invention relates to a hydraulic torque converter for a fork truck. The hydraulic torque converter comprises a cover wheel assembly, a turbine assembly, a pump impeller assembly and a guide wheel assembly, wherein the cover wheel assembly comprises a cover wheel hub and a cover wheel shell; the turbine assembly comprises a turbine hub and a turbine body; the pump impeller assembly comprises a pump impeller hub and a pump impeller body; the guide wheel assembly comprises a front retaining ring, a rear retaining ring and a guide wheel body; a three-coating-sheet bearing, an anti-thrust sheet and a ball bearing are arranged between the cover wheel hub and the turbine hub, between the turbine hub and the front retaining ring as well as between the rear retaining ring and the pump impeller hub; the bearing between the cover wheel hub and the turbine hub is a three-coating-sheet bearing; a three-coating-sheet bearing is arranged between the rear retaining ring and the pump impeller hub; and a three-coating-sheet bearing is arranged between the rear retaining ring and the ball bearing. According to the invention, the technical problems of unreasonable inside positioning, severe wearing, and noise generation of the traditional hydraulic torque converter for the fork truck are solved; and the hydraulic torque converter provided by the invention has low oil consumption, low noise and large torque.

Description

technical field [0001] The invention relates to a hydraulic torque converter for forklifts, which is mainly suitable for 1-4 ton forklifts. Background technique [0002] After analyzing the existing technical data and domestic and foreign automobile torque converters, it is found that there are two serious shortcomings, which lead to poor product reliability and high fuel consumption of the whole vehicle. 1. The performance of the torque converter is unreasonably matched with the engine, the fuel consumption of the forklift is high, and the traction is insufficient; 2. The internal positioning is unreasonable, the wear is serious, and there is noise. [0003] Now it is described as follows: [0004] 1. For the matching of the same engine with different types of torque converters, or the matching of different engines with the same torque converter, the greater the average output power value of the torque converter turbine shaft, the smaller the average unit fuel consumption ...
