Abstract

A brush device includes: a first and a second flange disposed side by side, each flange extending radially between a rubbing face intended to rub against a moveable element and a flange head intended to be connected electrically to another moveable element, a first plate rigidly fixed to the first flange only and extending tangentially above the head of the second flange, in such a way as to transmit, when this first plate is loaded by pressure unit, pressure forces on the second flange, a second plate, distinct from the first plate, rigidly fixed to the second flange only and extending tangentially above the head of the first flange in such a way as to bear on the first flange in the event of relative motion of the second flange with respect to the first flange towards the first moveable element.

Claims14

Dependent claims

A brush device (1) for transmission of electric power between first and second elements that are mobile in relation to one other, the brush device comprising:

first (11) and second (12) wafers disposed side by side, each of said first and second wafers extending radially between a contact surface and a wafer top (71, 72);
a first plate (41) rigidly affixed to the first wafer only, and extending tangentially over at least a portion of the top of the second wafer, such that when pressing means bias the first plate, the first plate transmits pressure forces onto the second wafer via contact between the first plate and the second plate;
and
a second plate (42), distinct from the first plate, rigidly affixed to the second wafer only, and extending tangentially over at least a portion of the top of the first wafer so as to press on a topmost portion of said first wafer in case of relative movement of the second wafer in relation to the first wafer toward the first mobile element,
wherein the first and second plates are configured such that when the first plate (41) transmits the pressure forces onto the second wafer (12), the second plate (42) is distanced from a topmost portion of said first wafer by 100 μm to 1 mm.

2 more elements

A brush device (1) for transmission of electric power between first and second elements that are mobile in relation to one other, the brush device comprising:

a first wafer (11);
a second wafer (12) positioned adjacent to the first wafer;
a first plate (41), with a first fixed end rigidly affixed to the first wafer and a first free end extending tangentially over an entirety of a first top portion (31) of the first wafer and over a portion of a second top portion (32) of the second wafer;
a second plate (42), with a second fixed end rigidly affixed to the second wafer and a second free end extending tangentially over an entirety of the second top portion of the second wafer and over a portion of the first top portion of the first wafer,
a lowermost surface of the first plate, facing a topmost surface of the first top portion of the first wafer, being spaced from the topmost surface of the first wafer such that the second free end of the second plate is positioned between the lowermost surface of the first plate and the topmost surface of the first wafer,
wherein, upon a force being applied to an upper surface of the first plate, the first plate transmits pressure forces onto the second wafer via contact between the first plate and the second plate, and
wherein, upon relative movement of the second wafer relative to the first wafer in a downward direction, a lowermost surface of the second plate presses upon the first top portion of the first wafer.
