Conveyor wheel for combustion air blower of vehicle heating device, has conveying surfaces provided in hub region at axial side of wheel body, where conveying surfaces extend from radially inward to outward

摘要

The wheel (24) has a wheel body (26) including a ring-like conveyor region (28) in a radial external region, where the region is opened in a direction of a rotational axis at an axial side (32) of the body. A set of conveying blades (34) is consecutively provided in a circumferential direction, and a hub region (36) is connected to the conveyor region for rotationally connecting the wheel with a driving element (20). A set of conveying surfaces (46) is provided in the hub region at the axial side of the wheel body, where the conveying surfaces extend from radially inward to outward. An independent claim is also included for a combustion air blower, comprising a blower casing.
