Abstract: A separation element is configured to separate a working chamber from a compensation chamber of a hydraulic anti-vibration module for mounting an engine on a vehicle body. The separation element includes a first duct extending between a first mouth and a second mouth. In embodiments, the first mouth is provided in a first face of the separation element and is configured to be fluidically connected to the working chamber, and the second mouth is provided in a second face of the separation element and is configured to be fluidically connected to the compensation chamber. In embodiments, the first mouth includes a plurality of openings.

Abstract: The invention relates to a bracket for supporting an electric motor on a chassis of a vehicle. The bracket includes a first half shell defining a first half space and a second half shell defining a second half space. In embodiments, the first half shell and the second half shell are made from a plastic material, which may in particular comprise a polymer material. In embodiments, the first half shell and the second half shell are fixed to each other, such as by welding, such that the first half shell and the second half shell define a cavity within the bracket that includes the first half space and the second half space.

Abstract: A partition member of an anti-vibration hydraulic mount includes a first channel and a second channel between the working chamber and the compensating chamber. The partition member includes a membrane secured in a receiving cavity. The membrane divides the receiving cavity into two sub-spaces separated fluidically from each other. The membrane comprises a closing device configured to have an open configuration, in which the closing device is spaced apart from the central opening, and a closed configuration, in which the closing device abuts against the central opening to close the central passageway.

Abstract: A damping device for a motor vehicle is particularly suited for damping starting and stopping impacts of a motor vehicle engine. The device has first and second chambers filled with a damping medium and separated by an intermediate plate. The chambers are each bounded by a bellows and by a face plate. A damping channel connecting the chambers is formed in the intermediate plate. In order to achieve a damping effect depending on the operating mode of the motor vehicle engine, the two chambers are connected by at least one bypass channel, which can be selectively opened or closed by way of a switchable valve. The switched state of the valve depends on the operating mode of the motor vehicle. There is also described a damping system for damping the starting and stopping impacts of a motor vehicle engine.

Abstract: A hydraulic antivibratory device is provided, comprising two rigid frames (1,2); an elastomer body (3) connecting the two frames together and forming two sealed chambers (A, B) at least partially therewith; a restricted passage (7) causing the two chambers to communicate permanently with each other; a liquid mass (L) filling the two chambers and the restricted passage; and a deformable valve (8) partially defining one of the two chambers (A), and mounted between two grids (9, 10). This valve is in the form of a biconvex lens, only the central part of which is in permanent contact with the two grids and is clamped therebetween.
