Abstract
An electric motor for a motor vehicle, in particular for a braking or steering system, comprising a motor housing with a housing cover, and a stator inserted in the motor housing comprising a ring-shaped switching unit, which is arranged on a front side facing the housing cover, wherein at least one spacer element axially protruding in the direction of the housing cover is arranged on the switching unit, wherein the spacer element is designed to be elastic at least in the radial direction and/or the tangential direction.
Claims9
An electric motor for a motor vehicle, in particular for a braking or steering system, the electric motor comprising:
- a motor housing with a housing cover;
- and
- a stator arranged in the motor housing;
- a ring-shaped switching unit arranged on a front side facing the housing cover;
- and
- at least one axially protruding spacer element arranged on the switching unit in the direction of the housing cover, the spacer element being elastic at least in a radial direction and/or a tangential direction,
- wherein the spacer element is a column body with a tip on its free-end side, and
- wherein the tip has a contact surface for the housing cover, and wherein the contact surface has two different pitches.
An electric motor for a motor vehicle, in particular for a braking or steering system, comprising a motor housing with a housing cover;
- a stator provided within the motor housing;
- an annular switching unit arranged on an end face facing the housing cover,
- wherein an at least one spacer element is arranged on the annular switching unit, where the at least one spacer element projects axially upwards in the direction of the housing cover and exerts a prestressing force on the housing cover through elastic deformation or bending,
- wherein the at least one spacer element is cylindrical or bolt-shaped and has a slot on the free end for elastic deformation,
- wherein the slot extends transversely through the free end and substantially intersperses the free end of the at least one spacer element along a transverse direction, so that the free end on a bearing plate side is roughly U-shaped in cross section, and
- wherein the spacer element has an elastic design and is oriented at least in the radial direction and/or tangential direction.
