#CMT# #/CMT# In a flexible inertia wheel for a combustion engine, to be placed between an automobile engine crankshaft and transmission and comprising an inertia mass (21, 31), a flexible plate (22, 32) and fixing holes (23, 33), the flexible plate is inserted into the inertia mass during casting. #CMT# : #/CMT# An independent claim is included for a method for production of the flexible inertia wheel, from a flexible plate (32, 33) obtained by stamping and an inertia mass (21, 31) obtained by molding, by inserting the plate into the mass during molding. #CMT#USE : #/CMT# As an inertia wheel for a combustion engine (specifically an internal combustion engine) in an automobile. #CMT#ADVANTAGE : #/CMT# The flexible inertia wheel is obtainable by a simple, inexpensive procedure, and has performance equal to that of conventional analogs. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figures show frontal and side views of two forms of flexible inertia wheel for combustion engines, having an inertia mass in annular form or in the form of a central hub and two arms. 21, 31 : Inertia masses 22, 32 : Flexible plates 23, 33 : Fixing holes 34 : Arms 35 : Central hub 36 : Annular rim #CMT#MECHANICAL ENGINEERING : #/CMT# Preferred Construction: The flexible plate (22) and the inertia mass (21) are fixed together, in which case preferably the mass is annular and fixing holes (23) are pierced through the plate; or alternatively the plate (32) and mass (31) are relatively movable, in which case preferably the mass consists of an annular rim (36), a central hub (35) and at least two arms (34). #CMT#METALLURGY : #/CMT# Preferred Materials: The sheet (22, 32) is of elastic material (specifically steel) and the mass (21, 31) is of cast iron. Preferred Process: The plate (22) is inserted into the casting using a foundry process ensuring complete adhesion between the plate and the mass (21); or alternatively the parts of the plate (32) to be contacted with the mass (31) are treated before molding to ensure moveability of the plate relative to the mass. |
