Title:
自動車用ホイールリム
Document Type and Number:
Japanese Patent JP2012502842
Kind Code:
A
Abstract:
The invention relates to a wheel rim for a motor vehicle which can be economically manufactured, with a wheel disc made of steel sheet and a rim flap running around the circumference of the wheel disc. Due to the fact that the steel sheet of the wheel disc is formed from at least three superimposed steel layers, joined to one another by roll-bonding in a non-detachable manner, of which the inner core layer has a lower strength than the outer layers, it is thereby guaranteed that the wheel rim according to the invention, with a low weight, can safely accommodate the forces arising in practical operation.
