Modeling and analysis of wet friction clutch engagement dynamics

Mechanical Systems and Signal Processing, 2015
Abstract 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 ...

Frictional Torque Transfer Behaviors of Friction Pads in Wet Clutch Engagement

Volume 15: Advances in Multidisciplinary Engineering, 2015
For stable frictional torque transfer, wet clutch pads have the functional requirements of a high traction and a low wear rate with positive μ-V frictional characteristics. However, because of the intrinsic negative μ-V frictional characteristics of a friction material that has a static friction coefficient greater than its kinetic friction coefficient,

Temperature Analysis of Wet Clutch Surfaces During Clutch Engagement Processes Based on Friction Pad Patterns

International Journal of Automotive Technology, 2020
Temperature distributions of wet clutch contact during engagement and disengagement processes are investigated considering lubricant flow behaviors in the gap between the friction pad and steel separator. Frictional heat generated by wet clutch contact in repeated operational modes that simulates high thermal endurance performance of a wet clutch ...

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 ...

Experimental Characterization of Wet Clutch Friction Behaviors Including Thermal Dynamics

SAE International journal of engines, 2009
Wet clutches are widely used in automotive systems. They are essential parts of automatic transmissions, modern All-Wheel-Drive systems or dual-clutch transmissions. Regardless of the area of application, a good knowledge of clutch friction behaviors is crucial for the clutch control system development. This paper considers two important factors of the

Fluid Dynamic Analysis and Experimental Study on Wet Friction Clutch

Applied Mechanics and Materials, 2011
When the multi-disk clutch is in disengaged operation, friction plates and mating plates may not separate absolutely, in order to avoid the slipping friction and reduce the clutch’s overheating, the lubricant pressure between the plates should distribute equably in design.

Wet clutch friction characteristics obtained from simplified pin on disc test

Tribology International, 2008
Abstract 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. The transferred torque is normally investigated in test rigs where the friction in a sliding interface between a friction disc and separator ...

Analysis of Temperature Field on Combining Friction Discs of Wet Clutch

Applied Mechanics and Materials, 2014
Because of overheat and over wear, the distortion and invalidation will be produced easily in combining friction discs of wet clutch of heavy vehicle transmission system. So the paper studies the sliding friction force of a pair of steel and friction disc, calculates the heat flow density, obtains the heat exchange function with axial symmetry, and ...
