FLEXIBLE HYDRAULIC BRAKE LINE ASSEMBLY FOR MOTOR VEHICLE WHEELS

摘要

Hydraulic fluid is supplied to hydraulic brake cylinders for calipers (16) and brake shoes of a motor vehicle through brake line assemblies (20) each including a flexible multi-layer high pressure brake hose (30) having an end portion receiving an inwardly forged end portion (42) of a small diameter high pressure steel tube. A metal collar (50) receives each tube (32, 34) and is secured to the tube by a crimp (51) or threads (44) and/or a spring retaining washer (136), and is also crimped onto an end portion of the hose. The opposite end portion of each metal tube is flared and receives a tubular flare nut (38) which may be threaded directly into a brake caliper or a brake control valve. The collar may be progressively formed from sheet metal, and may be secured to the tube by a non-circular crimp. Circumferentially spaced ears may be formed on tube and project into corresponding grooves within the collar.
