Brush holder for holding at least two brushes for a sliding contact arrangement, electrical machine and motor vehicle

A brush holder for holding at least two brushes for a sliding contact arrangement, comprising:

• an intermediate element and two contact elements for electrically contacting at least one of the brushes, the contact elements being arranged on two opposite sides of the intermediate element and the intermediate element having a receptacle extending through the opposite sides for a rotating shaft, and wherein the contact elements each have at least one contact section which protrudes laterally beyond the intermediate element.

A brush holder for holding at least two brushes for a sliding contact arrangement, comprising:

• an intermediate element and two contact elements for electrically contacting at least one of the brushes, the contact elements being arranged on two opposite sides of the intermediate element and the intermediate element having a receptacle extending through the opposite sides for a rotating shaft, and wherein the contact elements have an identical geometry.

A brush holder for holding at least two brushes for a sliding contact arrangement, comprising:

• an intermediate element and two contact elements for electrically contacting at least one of the brushes, the contact elements being arranged on two opposite sides of the intermediate element and the intermediate element having a receptacle extending through the opposite sides for a rotating shaft, and wherein the intermediate element has at least one cooling duct extending inside the intermediate element.

A brush holder for holding at least two brushes for a sliding contact arrangement, comprising:

• an intermediate element and two contact elements for electrically contacting at least one of the brushes, the contact elements being arranged on two opposite sides of the intermediate element and the intermediate element having a receptacle extending through the opposite sides for a rotating shaft, and wherein the intermediate element has on the opposite sides in each case at least one pin protruding from the respective side which extends through a corresponding through hole in the adjacent contact element, the contact elements each being attached to the intermediate element by reshaping the pin.

An electrical machine comprising at least one brush holder for holding at least two brushes for a sliding contact arrangement, the brush holder comprising:

• An intermediate element and two contact elements, a first one of the contact elements being arranged on a first side of the intermediate element for electrically contacting at least a first one of the brushes, a second one of the contact elements being arranged on a second side of the intermediate element for electrically contacting at least a second one of the brushes, the contact elements thus being arranged on two opposite sides of the intermediate element, the intermediate element having a receptacle extending through the opposite sides for a rotating shaft and the intermediate element and contact elements being configured to support the first one of the brushes and the second one of the brushes spaced apart in an axial direction of the rotating shaft.

An electrical machine comprising at least one brush holder for holding at least two brushes for a sliding contact arrangement, the brush holder comprising:

• an intermediate element and two contact elements for electrically contacting at least one of the brushes, the contact elements being arranged on two opposite sides of the intermediate element and the intermediate element having a receptacle extending through the opposite sides for a rotating shaft, and wherein the brush holder is arranged in a wet space of the electrical machine which is at least partially filled with an insulating coolant.

An electrical machine comprising at least one brush holder for holding at least two brushes for a sliding contact arrangement, the brush holder comprising:

• an intermediate element and two contact elements for electrically contacting at least one of the brushes, the contact elements being arranged on two opposite sides of the intermediate element and the intermediate element having a receptacle extending through the opposite sides for a rotating shaft, and wherein the intermediate element of the brush holder has at least one cooling duct extending inside the intermediate element, the intermediate element abutting on a housing component of the electrical machine, and a coolant can be supplied to the cooling duct via a cooling duct of the housing component.

A motor vehicle comprising at least one electrical machine including at least one brush holder for holding at least two brushes for a sliding contact arrangement, the brush holder comprising:

• an intermediate element and two contact elements, a first one of the contact elements being arranged on a first side of the intermediate element for electrically contacting at least a first one of the brushes, a second one of the contact elements being arranged on a second side of the intermediate element for electrically contacting at least a second one of the brushes, the contact elements thus being arranged on two opposite sides of the intermediate element, the intermediate element having a receptacle extending through the opposite sides for a rotating shaft, and the intermediate element and contact elements being configured to support the first one of the brushes and the second one of the brushes spaced apart in an axial direction of the rotating shaft.
