Problems solved by technology

[0002] With the rapid development of China's economy, the volume of import and export goods has increased rapidly. As the main distribution center for import and export goods, the port tractor is characterized by low speed, high torque, flexible steering, flexible start, smooth start, automatic shifting, and reliability. High performance, but most of the chassis transmissions use foreign automatic gearboxes, which are expensive, and domestic tractors cannot meet the use requirements

Embodiment Construction

[0050] In order to realize low-speed high-torque and high-speed locking functions, the present invention proposes a high-capacity locking hydraulic torque converter.

[0051] like figure 1 As shown, the hydraulic torque converter includes a cover wheel assembly 1, a turbine assembly 2, a pump wheel assembly 3 and a guide wheel assembly 4; wherein the cover wheel assembly 1 and the turbine assembly 2 form a locked working condition; the pump wheel 5, the turbine assembly 6, The guide wheel 7 forms a torque-changing condition; the performance of the high-capacity closed-type hydraulic torque converter is realized by adjusting the angle of the pump wheel blade and the parameters of the guide wheel blade to achieve the performance of the hydraulic torque converter.

[0052] The specific parameters are:

[0053] The diameter of the circulating circle of the hydraulic torque converter φD is 340±4mm;

[0054] The average inlet and outlet radii of the streamline between the guide wh...

Abstract

The invention relates to a hydraulic torque converter mainly suitable for a port wharf traction vehicle. The hydraulic torque converter comprises a cover wheel assembly, a turbine assembly, a pump wheel assembly and a guide wheel assembly, wherein the cover wheel assembly and the turbine assembly form a locking working condition; a pump wheel, a turbine and a guide wheel form a torque conversion working condition; and the performances in the high-capacity locked type hydraulic torque converter realize the performances of the hydraulic torque converter by adjusting the angles of pump wheel blades and parameters of guide wheel blades. The hydraulic torque converter adopts a matched engine torque range from 1200-1800 Nm, is wider in range, can realize low speed and high torque, and achieves high-speed locking function.

Description

technical field [0001] The invention relates to a hydraulic torque converter, which is mainly suitable for traction vehicles in ports and wharves. Background technique [0002] With the rapid development of China's economy, the volume of import and export goods has increased rapidly. As the main distribution center for import and export goods, the port tractor is characterized by low speed, high torque, flexible steering, flexible start, smooth start, automatic shifting, and reliability. However, most of the chassis transmissions use foreign automatic gearboxes, which are expensive, and domestic tractors cannot meet the use requirements. Contents of the invention [0003] Aiming at the problems mentioned in the background technology, the present invention proposes a high-capacity lock-up hydraulic torque converter that can realize high torque at low speed, stable start, high-speed lock-up and high reliability. [0004] Concrete technical scheme of the present invention is...
