A shock mounting system for affixing a motor driven pump, a plurality of hydraulic valves and accumulators, and motion sensing devices to a vehicle to minimize the transmission of noises to the hydraulic unit and the vehicle. Each mounting point comprising a mounting stud fixed to the vehicle, a hole in the hydraulic unit, a resilient bushing received in the hole, and a plurality of cylindrical segments having outer surfaces contacting the bushing and inner surfaces contacting the stud. Each stud urges the corresponding segments radially outwardly into compressing engagement with an inner surface of the resilient bushing. Each segment includes a retaining rim and each mounting stud includes a corresponding retaining ledge which, upon adequate penetration of the stud into the bushing, allow the segments to collapse under the urging of the resilient bushing radially inwardly inter-engaging the rim and ledges to hold the stud within the bushing.
A hydraulic control unit having a pair of generally parallel cylindrical bores and a third cylindrical bore having a cylindrical axis extending generally perpendicular to the parallel cylindrical bores, the parallel bores adapted to receive a pair of generally parallel support pins and the third cylindrical bore adapted to receive a transverse support pin, and three bushings, each received in a corresponding cylindrical bore for providing mechanical vibration isolation between the support pins and the unit, and further including a plurality of wedges within each bushing to be engaged by and expanded radially outwardly by the introduction of a support pin into the corresponding bushing.
A method of assembling a hydraulic control unit to a vehicle to limit vibrational transmission between the unit and the vehicle, comprising:
A three point shock mounting system for affixing a hydraulic unit of a type having a motor driven pump, a plurality of hydraulic valves and accumulators, and motion sensing devices to a vehicle to minimize the transmission of road and vehicle noises to the hydraulic unit and the transmission of unit operating noise to the vehicle, characterized by each mounting point comprising a mounting stud fixed to the vehicle, a hole in the hydraulic unit, a resilient bushing received in the hole, and a plurality of cylindrical segments having outer surfaces contacting the bushing and inner surfaces contacting the stud;
