Hydroelastic support assembly

A hydroelastic support assembly comprises a frusto-conically shaped rubber support (10) connected to a vehicle engine by an upstanding stud (12) and connected to the vehicle body by a metal platform (14). The hollow interior of the rubber support (10) defines a main hydraulic chamber (22) which is open to a damping cassette (24) via an aperture (18) in the platform (14). The cassette (24) comprises a compensation chamber (30) having a flexible wall (28) and which is connected to the main hydraulic chamber (22) via a restricted annular canal (32) to provide hydraulic damping. A flexible membrane (40) provides damping of low amplitude vibrations. The cassette (24) is made substantially completely of thermoplastic or composite material and is thus relatively inexpensive and light in weight. It is secured in the assembly by means of structural adhesive (46) and held in position while the adhesive sets by clips (47).

Vibration damper for a motor vehicle

A vibration damper for a motor vehicle may include a damper tube, a piston rod that moves in the damper tube, a working piston attached to the piston rod that divides the damper tube into two working spaces, and first and second damping valves each with an adjustable damping force. Damping liquid may pass through the first damping valve as the piston rod retracts and through the second damping valve as the piston rod extends. Each damping valve may include a valve body that can be moved by a separate, controllable drive device between a closed position and an open position to set a throughflow cross section of each respective damping valve. The valve bodies may be loaded by restoring means counter to an actuating force of the drive device. A first of the restoring means may load a first of the valve bodies into its open position, and a second of the restoring means may load a second of the valve bodies into its closed position.

The vibration-isolating zones may be further supported by the housing of the vibratory element to maintain the structural integrity around the zones and to thereby alleviating weakness conditions that might subject the toothbrush to fatigue and breakage conditions.

TORSIONAL VIBRATION DAMPER WITH DISCRETIZED HUB

The disclosed invention is a novel method for constructing a Torsional Vibration Damper (TVD). The traditional means used to construct the hub of the TVD was to employ a single material. The disclosed invention essentially discretizes the construction of the TVD hub into three regions: nose, spokes, and flange, and simultaneously aligns unique materials and manufacturing methods for each region with the structural loads borne thereby. Consequently, the invention helps in reduces four unwanted characteristics: (1) mass; (2) polar mass moment of inertia; and (3) casting scrap; and (4) cost. Furthermore, because of this construction other enhancements to the axial and angular structural integrity of the TVD can be reaped in certain cases.
