Modeling Heat Transfer in a Wet Clutch

SAE Technical Paper Series, 1990
<div class="htmlview paragraph">The results of research involving the development and verification of a heat transfer model for a multiple-plate wet clutch are presented. Three specific operating conditions were considered: (1) engaged and slipping, (2) engaged and not slipping, and (3) disengaged.

A Wet Clutch for Farm Tractors

SAE Technical Paper Series, 1968
<div class="htmlview paragraph">Many of the modern, heavy-duty farm, construction, and industrial machines are being outfitted with some type of wet clutch. Either mechanically or hydraulically actuated, these oil-cooled multidisc clutches have much to offer when installed in the new higher horsepower equipment.

Adaptive Feed-Forward Control of the Clutch Filling Phase for Wet Dual Clutch Transmission

IEEE Transactions on Vehicular Technology, 2020
Clutch fill control in clutch-to-clutch shift process is an essential technique to ensure smooth and precise synchronization of clutches. The filling control methods proposed in previous works are difficult to apply to production vehicles because of huge calibration effort and numerical issues of the system model.

Research on the Wet Clutch Engagement Torque

Volume 7: 2nd Biennial International Conference on Dynamics for Design; 26th International Conference on Design Theory and Methodology, 2014
The driving performance of the vehicle with automatic transmission is influenced by the performance of the wet clutch directly. But at present it is still a challenge to build a reliable predictable model for the torque of the engagement process of the wet clutch.

Investigation of thermoelastic instabilities of wet clutches

2013 IEEE International Symposium on Assembly and Manufacturing (ISAM), 2013
A bench experiment was designed to test the rotational speed and torque of the wet clutch, so as to calculate the equivalent friction coefficient. With this coefficient, the unstable behavior of friction systems with lubrication can be researched by a similar method with dry friction systems.

Paper 16: Friction in Wet Clutches

Proceedings of the Institution of Mechanical Engineers, Conference Proceedings, 1967
This paper is intended to demonstrate that designers of wet clutches for power transmission can obtain the optimum friction characteristics for specific applications by considering the interaction between friction materials and lubricants. A friction clutch plate rig is described and the friction results obtained are presented.

Estimation of the Clutch Characteristic Map for an Automated Wet Friction Clutch Transmission

SAE Technical Paper Series, 2016
<div class="section abstract"><div class="htmlview paragraph">Higher demands on comfort and efficiency require a continuous improvement of the shift process. During the launch and shift process the clutch control is used to get a smooth and efficient behavior. In this short time of acting the shifting behavior can be rated.

Engagement Characteristics of Wet-Type Clutches

SAE Technical Paper Series, 1959
<div class="section abstract"><div class="htmlview paragraph">THIS PAPER presents a mathematical analysis of clutch engagement under certain idealized conditions and the related experimental work. The analysis is divided into several cases concerning pure inertia load acceleration and inertia load with a superimposed “work” torque load.</

The Wet Clutch Pressure Control of Dual Clutch Transmission Based on FCMAC

Applied Mechanics and Materials, 2012
A wet clutch pressure control system of dual clutch transmission was presented in this paper, and clutch pressure intelligent control arithmetic based on FCMAC(Fuzzy Cerebellar Model Articulation Controller) was designed to realize accracy control of clutch pressure. The intelligent control system was verified by experiment, and the rusults showed that
