Device for the temperature-controlled arresting of the impeller wheel of a fan for internal combustion engines

摘要

In a device for the temperature-controlled arresting of the impeller wheel of a fan for internal combustion engines, the impeller wheel being connected by way of an automatic coupling to a drive shaft and having an actuatable mechanical brake for arresting it, a brake arrangement less sensitive to dirt from the incident air, which comprises a drum brake, is proposed in order to increase the operating reliability.
