Abstract
A top mount assembly includes a resilient isolator designed to be seated on an upper end of an actuator. A guiding sleeve is seated on the isolator and includes an upstanding annular wall forming a cavity in an upper surface of the guiding sleeve. At least one Belleville spring is mounted in the cavity to permit deflection of the assembly during the operational range of the actuator. A thrust plate is mounted on the Belleville spring and attached to the body.

A vehicular suspension system comprising:
- (A) a hydraulic actuator for supporting a vehicular body;
- and
- (B) a top mount assembly attaching the actuator to the body, the mounting assembly including
- (a) a resilient isolator seated on the actuator;
- (b) a guiding sleeve seated on the simulator having a recessed cavity;
- (c) Belleville spring means received within the cavity;
- (d) thrust plate means seated on an uppermost surface of the Belleville spring means;
- (e) means for securing the actuator to the thrust plate means;
- and
- (f) means for securing the thrust plate means to the vehicular body.
