Abstract
The invention provides hydraulic mount and an assembling method thereof. The hydraulic mount comprises an integrally formed outer support, an inner sleeve, a rubber main spring, an inner frame, hydraulic assemblies, and a support arm. The rubber main spring comprises a tubular portion, a base portion, and a connecting portion connected between the tubular portion and the base portion. The inner sleeve is arranged in the tubular portion. The inner frame is arranged in the base portion. The internal of the outer frame is provided with a holding cavity. The inner sleeve, the rubber main spring, and the inner frame are used as an integrated body and are assembled with the hydraulic assemblies, and the integrated body is held in the holding cavity. One end portion of the support arm is mounted in the tubular portion by interference press fitting.
