Abstract
A new and improved power steering hose assembly is described, which may comprise a core hose layer, a first reinforcing layer, an intermediate hose layer, a second reinforcing layer and an outer hose layer. The first reinforcing layer has a braid pattern formed in a 1-over, 1-under pattern. The intermediate hose layer is positioned over the first reinforcing layer. The second reinforcing layer is disposed over the first reinforcing layer. The second reinforcing layer has a braid pattern formed in one of a 3-over, 3-under pattern or a 2-over, 2-under braid pattern. The outer hose layer is positioned over the second reinforcing layer.
Claims18
A power steering hose assembly, comprising:
- a core hose layer;
- a first reinforcing layer over said core hose layer;
- an intermediate hose layer over said first reinforcing layer;
- a second reinforcing layer over said first reinforcing layer, said second reinforcing layer having a braid pattern formed in one of a 3-over, 3-under pattern or 2-over, 2-under pattern;
- and,
- an outer hose layer over said second reinforcing layer.
A method of making a power steering hose, comprising:
- forming a core hose layer;
- forming a first reinforcing layer over the core hose;
- forming an intermediate hose layer over the first reinforcing layer;
- braiding a second reinforcing layer over the intermediate hose layer in one of a 3-over, 3-under pattern or a 2-over, 2-under pattern;
- and
- forming an outer hose layer over the second reinforcing layer.
A power steering hose assembly, comprising:
- a core hose layer;
- a first reinforcing layer over said core hose layer, said first reinforcing layer being one of a braid pattern formed with polyester yarn in one of a 1-over, 1-under pattern or a plastic barrier layer;
- an intermediate hose layer over said first reinforcing layer, said intermediate layer being a friction rubber layer;
- a second reinforcing layer over said first reinforcing layer, said second reinforcing layer being a polyester yarn and having a braid pattern formed in one of a 3-over, 3-under pattern or a 2-over, 2-under pattern;
- and,
- an outer hose layer over said second reinforcing layer.
