Abstract
A shock absorber includes an extruded reservoir housing and a sleeve with position valving therein. The shock absorber coordinates the position valving and valving in the piston assembly in a manner such that the position of the piston assembly relative to the position valving becomes a factor in determining changes in valving.
Claims21
A shock damping apparatus for damping relative motion of interconnected elements of a vehicle comprising:
- a cylinder assembly including reservoir means and sleeve means;
- piston means including rod means having a piston assembly at one end and means at a second end for connection to said vehicle, said piston assembly being slidably received within said sleeve means dividing said sleeve means into a compression chamber and a rebound chamber;
- first end cap means slidably receiving said rod means therethrough attached to a first end of said cylinder assembly, said first end cap means sealing said first end of said cylinder assembly and sealing around said rod means;
- and
- second end cap means attached to a second end of said cylinder assembly including means for sealing said second end of said cylinder assembly and means for connection of said second end cap means to said vehicle;
- said reservoir means including a plurality of longitudinally extending ribs on an interior surface extending from said first end to said second end, said sleeve means being of a predetermined diameter such that when the sleeve means is disposed within said reservoir means more than one of said plurality of ribs directly contacts and supports said sleeve means.
A process for manufacturing a shock damping apparatus including the steps of:
- extruding a reservoir housing having a plurality of ribs and channels extending generally from a first end to a second end on an interior surface thereof and cooling fins on an exterior surface;
- cutting the reservoir housing to a predetermined length;
- pressing a sleeve of a predetermined length into said reservoir housing wherein more than one of said ribs directly contacts and supports said sleeve;
- inserting a piston assembly with attached piston rod into said sleeve;
- fastening a first removable end cap to one end of said reservoir housing in a manner sealing said one end of said reservoir housing with said piston rod being slidably received therethrough;
- fastening a second removable end cap to a second end of said reservoir housing in a manner sealing said second end of said reservoir housing;
- and
- filling and pressurizing said shock damping apparatus with an oil and gas emulsion.
A cylinder assembly for a shock damping apapratus comprising reservoir housing means having longitudinally extending fins on an exterior surface and a plurality of longitudinally extending ribs and channels extending generally from a first end to a second end of an interior surface thereof and a generally cylindrical sleeve means of a predetermined diameter disposed within said reservoir housing wherein more than one of said ribs directly contacts and supports said sleeve means and said ribs and said channels cooperate with an exterior surface of said sleeve means to form at least one passageway.
