The influence of friction between elements of dual-mass flywheel on oscillatory phenomena in a car transmission

Automobile manufacturers, when designing new cars, are increasingly faced with the need to reduce the weight of components in order to achieve the required level of fuel consumption and environmental standards. As a result, internal combustion engines (ICEs) with a small number of cylinders are designed and manufactured, which allows to achieve an increase in output power due to increased pressure in the cylinder and more efficient fuel combustion.

Safety-overrunning ball-type clutch parts contact interaction features

The article deals with the field of machinery, namely, with the protecting of devices for mechanical driving systems. Safety-overrunning clutches, operating on gearing principle, where safety and overrunning parts are mutually integrated, are perspectives for the  building based on modular machines. This case is due to their compactness and low components, comparatively with combined constructions. New clutch design is investigated insufficiently.

Influence of vehicle acceleration intensity on dual-mass flywheel elements and transmission load

Modern high-torque low-speed internal combustion engines (ICEs) generate torsional vibrations close in disturbance frequency to gearboxes natural oscillation frequencies. Effective absorption of such oscillations requires a new torsional vibration damper between the internal combustion engine and gearbox design, which is implemented in the form of a dual-mass flywheel (DMF). One of the main reasons for DMF failure is its spring components destruction.
