Abstract
A suspension shock absorber for remote control (RC) cars includes an inner tube and an outer tube coaxial with each other. The hollow area inside the inner tube defines a hollow chamber where a piston and a piston rod slidably moves. A shock cap seals the top of the inner tube and the outer tube. The space between the coaxial inner tube and outer tube is used as an inter-tube bypass route through which bypass oil flows. The shock cap has a bypass passage connecting the inter-tube bypass route with the upper portion of the hollow chamber. A bypass valve in line with the co-axis of the inner tube and the outer tube is disposed on top of the shock cap and used to regulate the amount of oil flow through the bypass passage.
Claims16
A suspension shock absorber comprising:
- an inner tube comprising
- a first proximal end,
- a first distal end,
- a hollow space defining an inner chamber, and
- a bottom bypass port near the first distal end;
- an outer tube coaxial with the inner tube along a central axis and comprising a second proximal end and a second distal end;
- an inter-tube bypass route defined by a space between the outer tube and the inner tube;
- a piston rod slidably connected to the second distal end;
- a piston disposed in the inner chamber and defining a lower chamber within the inner chamber between the piston and the first distal end, wherein the lower chamber has a lower chamber volume;
- a volume spacer disposed in the lower chamber and capable of expanding and contracting when the lower chamber volume temporally changes;
- a shock cap connected to the first proximal end and the second proximal end, wherein the shock cap further defines a bypass passage fluidly communicating the inner chamber and the inter-tube bypass route;
- and
- a bypass valve connected to the shock cap, wherein the bypass valve adjustably regulates the bypass passage.
