Definitions

• a drive device for a fan module comprises an electric motor, a housing and an elastic element for vibration-damping attachment of the electric motor to the housing.
• the electric motor has a radial engagement element for engaging in the elastic element
• the housing has a radial recess for receiving the elastic element.
• the elastic element rotates the engagement element on a radial portion. Due to the special design of the elastic element, it is virtually impossible, even with greatly decreasing elasticity or damping capability of the elastic element, for example due to aging, wear or high temperatures, that the engagement element comes into contact with a boundary of the recess. As a result, shocks can be avoided and thus extends a life of the electric motor and acoustic interference in the range of the drive module can be prevented.
• the elastic element is symmetrically shaped with respect to rotation about a radius of the electric motor. Incorrect installation of the elastic element in an incorrect position can thereby be avoided. Additional features in the sense of a Poka Yoke ("avoidance of unfortunate mistakes") can be saved if necessary, which can lead to a further cost reduction.
• Figure 1 is a schematic exploded view of a fan module
• Figure 2 is a detail of the electric motor of Figure 1;
• FIG. 8 shows a vibration damper for the engagement element of FIG.
• FIG. 6 shows an elastic element 600 for engagement with the tab 145 from FIG. 5.
• a coordinate system again shows a radial direction x, an axial direction y and a circumferential direction z.
• External boundaries of the resilient member 600 are similar to the boundaries of the resilient member 300 of FIG. 3.
• the recess 305 is not cylindrical but slit-shaped to receive the tab 145 of FIG.
• the rounding like other roundings on the elastic element 130, can contribute to this. to increase a surface of the elastic member 130 and to prevent a risk of cracks in the area of sharp edges or corners.
• FIG. 8 shows an elastic element 800 for engagement with the engagement element 700 from FIG. 7.
• a coordinate system is shown for improved orientation.
• the view of the elastic element 800 takes place from the interior of the housing 120.
• the recess 305 corresponds to the tab 145 of Figure 7 and has in cross-section substantially the shape of an inverted U on.
