Abstract:
1. A cab mounting assembly for a vehicle, the cab mounting assembly comprising: a shock absorber having a pressure tube and a piston rod movable in an axial direction with respect to said pressure tube; an air spring assembly attached to said shock absorber; and a double path top mount attached to both said shock absorber and said air spring assembly, said double path top mount comprising: a dynamic air seal sealing a chamber of said air spring assembly, said dynamic air seal having a rigid inner member secured to said shock absorber, a rigid outer member secured to said air spring assembly and an elastomeric member separate from said elastomeric mount disposed between said rigid inner member and said rigid outer member; movement of said piston rod of shock absorber in the axial direction with respect to said air spring assembly being allowed by said elastomeric member; wherein said second cylindrical elastomeric member deflects in a radial direction when said piston rod moves in said first axial direction; and deflection of said second elastomeric member is independent from deflection of said first elastomeric member.
