The Automotive Friction Clutches Face Seal Axial Symmetric Modeling Problem
Applied Mechanics and Materials, 2012An axial clutch is one in which the mating frictional members are moved in a direction parallel to the shaft. One of the earliest of these is the cone clutch, which is simple in construction and quite powerful. However, except for relatively simple installations, it has been largely displaced by the disk clutch employing one or more disks as the ...

Methodology to Determine the Clutch Facing Sensitivity Regarding Judder in the Vehicle
SAE Technical Paper Series, 2010<div class="section abstract">Methodology to determine the clutch facing sensitivity regarding judder in the vehicle. Vehicle "Judder" is identified as low frequency and high amplitude vibrations that, depending on their intensity, can cause uncomfortable driving. There is a bench test developed specifically to measure the judder sensitivity of

Study on the Formability Rules with Precise Die Face for the Inner Clutch Shell of Automobile
Advanced Materials Research, 2013The ultimate goal of the metal forming industry is to form components made of a specific material into a required shape without experiencing wrinkling, bifurcation and spring-back. This study is devoted to develop the whole process by making rules of precision for specific part geometry.

Friction Behavior of Clutch-Facing Materials: Friction Characteristics in Low-Velocity Slippage
SAE Technical Paper Series, 1972<div class="htmlview paragraph">A study was made of details of friction characteristics of several kinds of clutch-facing materials of resin mold type. With particular attention given to the low-speed slip area, the following was made clear: There exists a thin film on the friction surfaces of facing and mating materials.

Experimental characterization of frictional behaviour of clutch facings using Pin-on-disk machine
Materials & Design, 2007During the clutch engagement manoeuvre, sliding contact occurs between the pair of clutch facings mounted on the friction disk and the counter faces belonging to the flywheel and the pressure plate. The transmitted torque is proportional to the overall coefficient of friction which depends essentially on temperature, normal pressure load and relative ...

Journal of Tribology, 1996
Abstract This paper presents a new theory on frictional vibrations of paper-based friction material considering the interaction between its deformation and the consequent lubricant flow inside it. A frictional vibration model is proposed, in which a poroelastic body saturated by a viscous liquid is introduced, and then a stability ...
