Damper assembly
A damper assembly includes a rod elongated along an axis. The damper assembly includes a body supported by the rod, the body having a first surface and a second surface opposite the first surface. The body and the rod define a passage between the body and the rod, the passage extending from the first surface of the body to the second surface of the body.
1. A damper assembly, comprising:
a rod elongated along an axis;
a piston supported by the rod, the piston having a compression surface and a rebound surface opposite the compression surface;
a first passage extending between the piston and the rod from the compression surface to the rebound surface of the piston;
a check disc supported by the rod, the check disc movable from an unflexed position to a flexed position to increase resistance to fluid flow through the first passage;
a housing supported by the rod, the housing defining a chamber in fluid communication with the first passage, the check disc being in the chamber; and an orifice disc in the chamber.
2. The damper assembly of claim 1 , wherein the piston defines a second passage extending from the compression surface to the rebound surface, and further comprising a blow off disc supported by the rod and selectively permitting fluid flow out of the second passage of the piston, the first passage extending between the rod and the blow off disc.
3. The damper assembly of claim 2 , further comprising a spring disc supported by the rod and urging the blow off disc toward the piston, the first passage extending between the rod and the spring disc.
4. The damper assembly of claim 3 , wherein the piston, the blow off disc, and the spring disc each include a notch, the first passage extending through the notches.
5. The damper assembly of claim 4 , wherein the piston, the blow off disc, and the spring disc each include a second notch, and the rod includes a rib disposed in the second notches.
6. The damper assembly of claim 1 , wherein the rod includes an axially elongated flat defining the first passage.
7. The damper assembly of claim 1 , further comprising a flow disc supported by the rod, the flow disc defining a radial passage in fluid communication with the first passage.
8. The damper assembly of claim 1 , wherein the check disc is movable from the unflexed position to a second flexed position, the check disc restricting fluid flow through the first passage in a first direction in the flexed position and restricting fluid flow through the first passage in a second direction opposite the first direction in the second flexed position.
9. The damper assembly of claim 1 , further comprising a second check disc supported by the rod, the check disc restricting fluid flow through the first passage in a first direction in the flexed position, and the second check disc selectively restricting fluid flow through the first passage in a second direction opposite the first direction.
10. The damper assembly of claim 1 , wherein the check disc is movable from the unflexed position toward the housing to the flexed position.
11. The damper assembly of claim 1 , wherein the housing includes a rib extending toward the check disk.
12. The damper assembly of claim 11 , wherein the rib includes a channel.
13. The damper assembly of claim 1 , further comprising a second orifice disc in the chamber, the check disc between the orifice disc and the second orifice disc.
14. The damper assembly of claim 1 , further comprising a top disc further defining the chamber, the top disc having an opening in fluid communication with the chamber.
15. The damper assembly of claim 14 , wherein the top disc includes a rib that extends toward the housing.
16. The damper assembly of claim 15 , wherein the rib defines a channel.
17. The damper assembly of claim 1 , further comprising a second check disc in the chamber, the check disc restricting fluid flow through the first passage in a first direction in the flexed position, and the second check disc selectively restricting fluid flow through the first passage in a second direction opposite the first direction.
18. A damper assembly, comprising:
a rod elongated along an axis;
a piston supported by the rod, the piston having a compression surface and a rebound surface opposite the compression surface;
a first passage between the piston and the rod, the first passage extending from the compression surface of the piston to the rebound surface of the piston;
a second passage extending from the compression surface to the rebound surface;
a blow off disc supported by the rod and selectively permitting fluid flow out of the second passage of the piston, the first passage extending between the rod and the blow off disc;
a spring disc supported by the rod and urging the blow off disc toward the piston, the first
passage extending between the rod and the spring disc; and
the piston, the blow off disc, and the spring disc each including a notch, the first passage extending between the rod and the spring disc.
19. A damper assembly, comprising:
a rod elongated along an axis; and
a piston supported by the rod, the piston having a compression surface and a rebound surface opposite the compression surface;
a passage between the piston and the rod, the passage extending from the compression surface of the piston to the rebound surface of the piston;
a check disc supported by the rod, the check disc selectively restricting fluid flow through the passage;
a housing supported by the rod, the housing defining a chamber in fluid communication with the passage, the check disc being positioned within the housing and in the chamber, the housing including a rib extending toward the check disk.
