  16. In claim 1, the fastening groove is, A movement path formed in a direction parallel to the coupling direction of the locking body and body plate; and A seating portion configured to be bent at a certain angle with respect to the above-mentioned moving path to seat the above-mentioned catch portion; Hydro Mount that further includes
  17. Core; A body plate comprising a plurality of fastening grooves arranged concentrically with the core on the radially outer side of the core and spaced apart along the circumference; Main rubber inserted between the core and body plate; A locking body comprising a plurality of locking portions capable of being coupled to the above-mentioned fastening groove; and It includes a nozzle assembly and a diaphragm sequentially laminated between the main rubber and the locking body, and The nozzle assembly and diaphragm include a plurality of sinking portions formed by being spaced apart along the circumference so that the catch portion can pass through, The above-mentioned locking portion includes a convex portion protruding toward the radial inner side of the locking body, and the convex portion is configured to move along the fastening groove formed on the outer surface of the body plate. The above fastening groove is, A movement path formed obliquely with respect to the coupling direction of the locking body and body plate; A seating portion configured to be bent at a certain angle with respect to the above-mentioned moving path to seat the above-mentioned catch portion; and A hydro mount comprising a transition path connecting the moving path and the seating portion by bending the moving path into a curved surface.
  18. In claim 2, as the locking portion is coupled to the fastening groove, the main rubber and diaphragm are compressed and twisted, and The above-described locking body and body plate are a hydro-mount joined by an elastic restoring force of at least one of the main rubber and diaphragm generated by twisting.

Description

Hydro-Mount The present invention relates to a hydro engine mount for a vehicle, and more specifically, to an assembly structure of a hydro mount. The engine mount connects the vehicle's powertrain to the vehicle body and supports the load of the powertrain. The engine mount includes rubber that acts as an insulator internally to isolate vibration and noise from the powertrain and to restrain its behavior, as well as stoppers that restrain the displacement of the rubber. Recently, hydro mounts that insert fluid into engine mounts are widely used to improve performance required in vehicles, such as R&H (Ride & Handling) and NVH (Noise, Vibration, and Harshness). As illustrated in FIGS. 1a and 1b, the hydro mount (500) comprises a main rubber (510), a core (530) and a core bolt (550) positioned radially inwardly concentric with the main rubber (510), a nozzle assembly (570) including an upper plate (571) and a lower plate (573) for damping through fluid, and a diaphragm (590) having a membrane (575) interposed on the inside. The hydro mount (500) assembles internal components as described above to provide damping performance at a specific frequency, and there are two main assembly methods for the hydro mount (500). The former is a curling type in which a nozzle assembly and a diaphragm are inserted into a pipe in which the main rubber (510) is vulcanized, and then the end of the pipe is curled by physical force. Although this type has a stable assembly structure, it has the disadvantage that parts are damaged when disassembled for reassembly or high-quality analysis after assembly. The latter is a hooking type in which the nozzle assembly and diaphragm are laminated, and the components are secured using a hook member made of plastic or metal. This method utilizes the elasticity of the hook member, which opens during the assembly process and ultimately returns to its original state. This type offers the advantage of high flexibility in terms of cost or weight due to the ability to use various materials for the hook member, as well as ease of reassembly and disassembly.
