A reel of a device for covering a heat exchanger of a vehicle according to the invention has at least two regions. One region is a shaft region implemented as a hollow shaft. The shaft region advantageously can withstand very good bending moments in the reel due to the airflow back pressure of the head-on wind and in turn prevent deformation of the reel. Furthermore, the hollow shaft advantageously has a reduced weight. An interface region is arranged at at least one end of the shaft region and has a connecting element to a drive unit. The connecting element may be, for example, a driveshaft head. The material of the interface region is selected such that, for example, when a higher torque is transmitted via the connecting element to start a frozen device, the frozen device can be subjected to a higher torque load. Advantageously, the reel can thus meet the requirements of less bending in the event of simultaneously withstanding higher torques. Vibration of the device used for coveringthe heat exchanger is effectively prevented, and therefore damage to adjacent components is further prevented. In addition, the air resistance of the vehicle is kept small.
根据本发明的用于遮盖车辆的换热器的装置的卷轴具有至少两个区域。一区域是实施成空心轴的轴区域。该轴区域有利地可非常良好地承受由于迎面风的气流背压而出现的在卷轴中的弯矩且进而防止卷轴的变形。此外,空心轴有利地具有较少的重量。接口区域布置在轴区域的至少一个端部处且具有至驱动单元的连接元件。在此连接元件可例如是驱动轴头。在此接口区域的材料选择如此选成,例如当较高的转矩须经由连接元件传递从而起动被冻住的装置时,可经受住较高的扭矩负荷。有利地,卷轴因此可在同时承受较高扭矩的情形中满足较少弯曲的存在的要求。有效防止用于遮盖换热器的装置的颤动以及由此还防止相邻构件的损伤。此外,车辆的空气阻力被保持较小。
