ABSTRACT:
This invention teaches an improved high capacity frictional shock-absorbing assembly. The assembly comprises a housing with a first threaded member which is fitted therein for axial movement. A second threaded member is rotatably-fitted in the housing, but is restricted against axial movement. The first and second members are designed with compatible threaded surfaces for frictional engagement therebetween. A compression member is provided within the housing. The compression member is in engagement with the first threaded member to resist the axial movement of the first threaded member as it moves in a direction that will compress the such compression member.
