Encapsulated brake system comprising cooling conductors and a linear drive

A brake assembly comprising:

• a housing enclosing an interior and having a main body;
• a shaft mounted on the main body to rotate about a central longitudinal axis, extending at least partially in the interior and having a connecting flange for the shaft accessible on the outside of the housing;
• a brake disc located in the interior and mounted on the shaft so as to be axially displaceable relative to the main body for conjoint rotation with respect to the central longitudinal axis, the main body including a first braking surface in the interior, against which the brake disc can be approached in the axial direction of the central longitudinal axis;
• a second braking surface, which lies beyond the brake disc in the axial direction with respect to the first braking surface and is mounted so as to be movable in the axial direction with respect to the main body;
• a linear drive which engages between the main body and the second braking surface, operates in the axial direction, and is configured to move the second braking surface in the axial direction relative to the main body against the brake disc to move the brake disc in the axial direction against the first braking surface, the linear drive being hydraulically actuated;
• and
• a cooling conductor thermally coupled at least to both braking surfaces and is configured to dissipate heat generated during braking at least from the two braking surfaces, at least a partial section of the cooling conductor being embedded in the main body.

An electric vehicle comprising:

• an axle;
• and
• a braking assembly configured to brake the axle, the braking assembly comprising:
• a housing enclosing an interior and having a main body;
• a shaft mounted on the main body to rotate about a central longitudinal axis, extending at least partially in the interior and having a connecting flange for the shaft accessible on the outside of the housing;
• a brake disc located in the interior and mounted on the shaft so as to be axially displaceable relative to the main body for conjoint rotation with respect to the central longitudinal axis,
• wherein the main body has a first braking surface in the interior, against which the brake disc can be approached in the axial direction of the central longitudinal axis,
• a second braking surface, which lies beyond the brake disc in the axial direction with respect to the first braking surface and is mounted so as to be movable in the axial direction with respect to the main body,
• a linear drive which engages between the main body and the second braking surface, operates in the axial direction, and is configured to move the second braking surface in the axial direction relative to the main body against the brake disc to move the brake disc in the axial direction against the first braking surface;
• and
• a cooling conductor thermally coupled at least to both braking surfaces and is configured to dissipate heat generated during braking at least from the two braking surfaces.
