Dana torque converter: What is the function of an automotive hydraulic torque converter?

2025-11-20

A hydraulic torque converter is a hydraulic component consisting of a pump impeller, a turbine, and a stator. It is installed between the engine and the transmission, using automatic transmission fluid (ATF) as its working medium, and serves to transmit torque, vary torque, shift gears, and function as a clutch. Now, let Dana, a leading manufacturer of torque converters, explain the role of the automotive hydraulic torque converter!

Torque Converter: Functions and Operating Principle of the Hydraulic Torque Converter

2025-11-20

In vehicles equipped with an automatic transmission, there is no clutch between the engine and the transmission; instead, their connection is established via a hydraulic torque converter. According to Dana, a leading manufacturer of torque converters, the torque converter serves two primary functions: first, it transmits rotational speed and torque; second, it provides a rigid coupling between the engine and the automatic transmission, facilitating smooth gear shifts.

Dana torque converter: What are the output characteristics of a hydraulic torque converter?

2025-11-20

When a torque converter is used in conjunction with an engine, the relationship among the input speed MB, the mechanical transmission speed MT, the turbine speed nT, and the torque converter’s output characteristics is referred to as the torque converter’s output characteristic. Different slip ratios of the hydraulic torque converter result in distinct output characteristics. So, for the Dana torque converter: what are the output characteristics of a hydraulic torque converter?

Dana Dana Torque Converter: What are the advantages of a hydraulic torque converter?

2025-11-20

The hydraulic torque converter achieves high efficiency—ranging from 85% to 92%—when operating near its rated conditions. The impeller is the core component of the hydraulic torque converter; its type, arrangement, and blade geometry determine the device’s performance. Some torque converters feature two or more turbines, stators, or pumps to deliver varying operational characteristics. So, what are the advantages of Dana’s hydraulic torque converters?

Dana Dana Torque Converter: What are the selection requirements for a hydraulic torque converter?

2025-11-20

Construction machinery typically handles heavy loads, operates in harsh environments, performs frequent work cycles at low speeds, and suffers from poor cooling conditions, resulting in a high thermal load on the engine. Under normal operating conditions, the engine’s power output must be reduced by 10% to 20%. Based on the performance requirements of construction equipment and the corresponding demands on engine power, what are the selection criteria for Dana torque converters—specifically, hydraulic torque converters?
