Abstract
A hydraulic body mount with a combined rubber cushion and a hydraulic module may include an inner shaft, a mounting plate, a mounting bracket, a main rubber element, an inner ring, a fluid track, an upper bellows, a washer, a lower bellows, an outer can, a rate plate, a lower bushing, a crash washer, a doubler plate, and a retainer bracket. The fluid track may be configured to receive a fluid via a fluid port. The upper and/or lower bellows may be configured to interact with the fluid. The rate plate may be configured to engage the lower bushing and may be deformed when receiving the at least a portion of the inner shaft.
Claims20
A hydraulic body mount assembly, the assembly comprising:
- an inner shaft;
- a plate secured to the inner shaft;
- a main rubber element formed about at least a portion of the inner shaft, plate, and a mounting bracket;
- an upper bellows formed about a fluid track, the upper bellows configured to engage the inner shaft;
- a lower bellows configured to engage the inner shaft and the fluid track;
- an outer can including a lower bushing and a rate plate, wherein the lower bushing and the rate plate is configured to receive the inner shaft, mounting bracket, upper bellows, fluid track, and lower bellows;
- and
- a retainer bracket that secures a crash washer to the lower bushing via the inner shaft.
A method for producing a hydraulic body mount, the method comprising:
- securing an inner shaft to a plate;
- molding a main rubber element about the inner shaft, the plate, and a mounting bracket;
- securing an upper bellows to a fluid track;
- inserting the upper bellows and the fluid track onto the inner shaft and sealing against the mounting bracket;
- inserting a lower bellows onto the inner shaft and sealing against the fluid track and the upper bellows;
- overmolding at least a portion of a rate plate into an outer can, forming a lower bushing;
- inserting the outer can, lower bushing, and the rate plate onto the inner shaft;
- securing a doubler plate on the outer can;
- and
- installing a crash washer onto the lower bushing and the inner shaft, wherein the crash washer is secured to the inner shaft and lower bushing via a retainer bracket.
