Electronic hydraulic mount-internal solenoid |
摘要 |
A hydraulic mount assembly includes a pair of mounting members connected to each other through a hollow elastomeric body of natural or synthetic rubber. The body is closed by a resilient diaphragm so as to form a cavity for damping liquid. A partition or plate is provided to divide the fluid filled cavity into two distinct chambers. A primary chamber is formed between the partition and the interior wall of the hollow body. A secondary chamber is formed between the partition and the interior wall of the diaphragm. The partition includes at least two passages connecting the two chambers. A sliding gate extends across the entry to the passages. This gate is displaceable to direct the flow of fluid between the primary and secondary chambers through a selected passage or passages in the partition. A solenoid actuator mounted on the partition includes multiple electric coils that allow the positive positioning of the gate. A control circuit with onboard transducers is provided to monitor vehicle operating and road conditions. A microprocessor acts in response to the sensed conditions causing the necessary sequential energization of the series of coils.
