Temperature Observation Model for Wet Clutch of 9AT Based on Heat Transfer Theories

2024 8th CAA International Conference on Vehicular Control and Intelligence (CVCI)
During vehicle driving, the surface temperature of the wet clutch is difficult to be measured directly, which poses a huge challenge for accurate clutch temperature control.

Research on Filling Control of Wet Clutch Based on Direct-drive Pump-controlled Actuator

International Symposium on Parameterized and Exact Computation, 2022
A novel direct-drive pump-controlled actuator is taken as the research object, and a system method of oil charging control is proposed for the filling phase of the wet dual clutch.

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.</

Engagement behavior of degrading wet friction clutches

2011 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2011
This paper presents modeling, simulation and experimental validation of the friction material degradation effects on the dynamic engagement behavior of a wet friction clutch system. The clutch system is modeled as a 3 DOF lumped-mass-spring-damper incorporating an extension of the Generalized Maxwell Slip (GMS) friction model.

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

MULTIPLE ENGAGEMENT WET CLUTCH HEAT TRANSFER MODEL

Numerical Heat Transfer, Part A: Applications, 2002
To optimize the thermal performance of transmission wet clutches during multiple engagements, a general thermal numerical model has been developed. At every cycle, temperatures are computed throughout the clutch materials until a periodic steady state is achieved.

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.

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.

A simplified wet friction clutch test apparatus

Tribotest, 1995
AbstractA small, economic, test rig to evaluate friction materials and fluids for wet clutch applications has been designed, built and commissioned. In this paper, the construction, operation and performance of the machine are described, and results are presented, for two sets of typical tests.
