HYDRAULIC VIBRATION ISOLATING SUPPORT OF POWER UNIT (VERSIONS) Russian patent published in 2014 - IPC F16F13/08 F16F5/00 

FIELD: machine building.

SUBSTANCE: as per the first version, a support with fasteners includes working and compensation chambers separated with an elastic diaphragm with throttle holes and a partition wall with holes. Chambers are restricted with a support unit, an elastic shell and an elastic diaphragm. The support has an additional elastic element located between the diaphragm with holes and the partition wall. The support housing has a conical part, against which the elastic shell and the support unit is borne. The inner central part of the housing includes a bar. As per the second version, chambers of the support are divided between themselves with a partition wall with throttle channels. The partition wall is made in the form of a bushing vibration isolator consisting of external and internal housings and an elastic element with throttle holes, which is located between them. The support has an elastic element or a bar transmitting the movement to its support part to the internal housing of the vibration isolator. As per the third version, chambers of the support are divided between themselves with a partition wall in the form of a plate-like vibration isolator with throttle channels. The vibration isolator consists of a lower housing with a central bar, an upper housing and an elastic element with throttle holes, which is located between them.

EFFECT: improvement of dynamic characteristics of a hydraulic support within the whole range of vibrations of a power unit.
