Transverse element provided with a nanocrystalline surface layer for a drive belt for a continuously variable transmission and method for producing it.

摘要

The invention relates to a steel transverse element (32) component of a drive belt (3) for a continuously variable transmission, which drive belt (3) comprises a number of such transverse elements (32) and one or more endless tensile elements (31) . Each transverse element (32) defines at least one recess (33) accommodating the one or more endless carriers (31) and bounded by a support surface (41), a side face (43) and by a concavely curved transition surface (42) that is provided there between. According to the invention the transverse element (32) is provided with a nanocrystalline surface layer at the location of a concavely curved transition surface (42).
