Wet Clutch Drag Loss Simulation for Different Clutch Patterns

SAE Technical Paper Series, 2022
<div class="section abstract"><div class="htmlview paragraph">Wet clutches drag loss simulation is essentially linked to the clutch friction surface patterns in addition to the main geometry and conditions of the interface (relative speed, separation, inner and outer radius, viscosity and boundary pressures).

Optimized Wet Clutch Design

SAE Technical Paper Series, 2020
<div class="section abstract"><div class="htmlview paragraph">Multi-plate wet clutches used in motorbikes transmit the torque by friction under pressure between driving and driven Plates. The life &amp; performance of the clutch for the friction material used, depends on amount of energy generated during clutch slip, amount &amp ...

Benchtop screening of wet clutch materials

Tribology International, 2018
Abstract To decrease development time, bench-top screening tests are often used to rank materials prior to selection for standardized full-scale component test rigs, in-service vehicle tests, or system field testing. This paper describes the results from screening tests of four different paper-based clutch materials using a small scale bench-top test

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.

Thermal Characteristics of a Wet Clutch

Journal of Tribology, 1999
A comprehensive formulation of the governing equations, boundary conditions, and numerical solution technique is presented for modeling the thermal aspects of the engagement process in a wet clutch. The thermal model includes full consideration of the viscous heat dissipation in the fluid as well as heat transfer into the separator, friction material ...

Wet Clutch Lining-Lubricant Additive Interactions

SAE Technical Paper Series, 1974
<div class="htmlview paragraph">Lubricant and lubricant additive interactions with clutch linings and lining materials were measured at elevated temperatures. Swelling, weight, and compressibility changes were related to material chemistry and endurance test results.

Pressure Estimation of a Wet Clutch

2014
In both DCTs and new ATs, the change of the speed ratio is regarded as the process of one clutch being engaged with the other being disengaged, namely, the clutch-to-clutch shift. For vehicles with a hydraulic cylinder as clutch actuator, the cylinder pressure control is important for good shift quality.

Wet Single Clutch Engagement Behaviors in the Dual-Clutch Transmission System

International Journal of Automotive Technology, 2018
A frictional torque was generated by a lubricated slip contact between a wet clutch pad and a steel separator during a wet clutch engagement. It is necessary to understand the generation of frictional torque to improve the performance of the frictional torque transfer and the durability of the wet clutch system.
