Abstract: A parking brake device is suitable for being installed in a casing of an electric machine that houses a rotary shaft and at least one rolling bearing for guiding the rotary shaft. The parking brake device includes an annular support suitable for being inserted between the rolling bearing and the casing, an annular sliding gear which is mounted so as to slide on the support between two end positions, which is locked against rotation on the support, and which has dog clutches suitable for engaging a notched wheel coupled to the rotary shaft, and an actuator suitable for moving the sliding gear between its two end positions.

Abstract: An assembly for an electric machine includes a casing made of conductive material and connected to a reference potential, a rotor having an axis of rotation, and an electrically conductive connecting element that is in electric contact with the casing and with an electrically conductive part of the rotor.

Abstract: A cooling device for cooling an electric machine of a motor vehicle includes a reservoir and a circuit fluidically connected to the reservoir. The reservoir is intended to be situated radially between a housing of the electric machine and a stator of the electric machine, with respect to an axis of the electric machine.

Abstract: A stator assembly for an electric machine includes a first housing portion, a second housing portion, a stator body inserted into at least the first housing portion, a link for rotatably linking the stator body with the first housing portion, a first attachment for attaching the stator body to the first housing portion, and a second attachment for attaching the two housing portions to one another. The assembly includes an annular seal inserted axially between the stator body and the first attachment as well as between the two housing portions.

Abstract: A device for turbocharging an internal combustion engine including a turbocompessor including a turbine driven by the engine exhaust gas and a compressor driven by the turbine and compresses the engine intake air. An air intake conduit connects the compressor output to an air intake manifold to the engine and includes a chamber for damping pulsations generated at the compressor output. The damping chamber is connected directly to the compressor output.

Abstract: An exhaust device for a motor vehicle multi-cylinder internal combustion engine including a cylinder head of the engine in which there are exhaust ducts, a first end of each of which is connected to a combustion chamber of the engine and a second end of which opens into a cavity or plenum of an exhausted manifold integrated into the cylinder head of which an outlet duct is externally connected to a device for removing contamination from the exhaust gases of an exhaust line of the vehicle. The cavity or plenum of the manifold is formed in an element attached inside the cylinder head, and the element is thermally decoupled from the cylinder head using a thermal decoupling mechanism.

Abstract: A supercharger arrangement for an engine assembly 10 is disclosed, the arrangement including first and second superchargers 22A, 22B that are mounted on the engine assembly by means of separate first and second mounting members 46, 48 respectively. Each mounting member defines an integrated supercharger lubrication conduit 62A, 62B, 64A, 64B and the present invention is characterized in that the superchargers 22A, 22B are of substantially identical construction and are separable from the first and second mounting members 46, 48. The integrated lubrication conduits 62A, 62B, 64A, 64B are routed through their respective said mounting members in such a manner as to enable the first and second superchargers to be mounted on the engine assembly 10 in substantially mirror image orientations thereabout.
