The mechanisms of wet clutch friction behaviour [PDF]
, 2010 Wet clutches are used in automatic transmissions to bring about gear changes and also to reduce energy loss in the torque converter. These friction devices are susceptible to stick-slip effects, which result in the vehicle giving an unsteady ride. Stick-slip effects can be avoided by ensuring the wet clutch and lubricant combination produces a friction

Lubricant ageing effects on the friction characteristics of wet clutches
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2010 The friction characteristics and performance of wet clutches have been investigated by several authors. Studies have also been made to understand the frictional performance during the service life of the clutch system. However, most lifetime studies have been conducted for systems with paper-based friction material so that systems using sintered bronze

Investigation of engagement characteristics of a multi-disc wet friction clutch
Tribology International, 2021Abstract A kinematic coupling model of the rotation-axial engagement process of friction elements is established based on the oil film dynamic pressure lubrication and an elastic contact model of the asperities. The engagement characteristics of the multi-disc wet friction clutch are analyzed. The equation for the transmission torque of the clutch is

Modeling and analysis of wet friction clutch engagement dynamics
Mechanical Systems and Signal Processing, 2015Abstract In recent years, there has been a significant increase in the usage of wet-friction clutches. Presently researchers across the globe are involved in improving the performance and lifetime of clutches through testing and simulation. To understand the clutch vibrational and dynamical behavior, an SAE#2 test setup mathematical model based on ...

Wet clutch friction characteristics obtained from simplified pin on disc test
Tribology International, 2008 The frictional behavior of wet clutches in vehicle drivetrains is critical for their overall behavior. During the development of new wet clutch systems there is a need to know this friction behavior.

Modelling the influence of velocity on wet friction-element friction in clutches
Industrial Lubrication and Tribology, 2018Purpose This study aims to establish a friction coefficient model relative to the rotation speed of a wet clutch engagement, which can predict friction coefficient under different stages of slipping velocity and different load pressures. In particular, the model has been improved by accounting the speed effect for the perdition of wet friction-element

Paper 16: Friction in Wet Clutches
Proceedings of the Institution of Mechanical Engineers, Conference Proceedings, 1967This 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.

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2017 The behavior of a wet clutch during engagement is of great importance to the durability of the clutch and the drivability of a vehicle. While many different factors influence the engagement behavior, the focus of this paper is to investigate only one ...

Engagement behavior of degrading wet friction clutches
2011 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2011This 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.

Contact properties of a wet clutch friction material
Tribology International, 2010Abstract Wet clutches are required to transmit torque and also prevent motion in automatic transmissions. Their performance is critically dependent on a friction material which comprises one of the contacting surfaces. Friction materials are usually a composite of fibres, naturally occurring minerals and particles of silicon and graphite, which are ...
