Hydraulic brake for bicycles and light, 2004.

摘要

Hydraulic brake adapted to bicycles and lightweight vehicles. The invention relates to a device making it possible to generalise use of the hydraulic brake mainly adapted to bicycles. It consists of a casing made from stamped sheet metal 1 comprising two master cylinders 8 and 9 with pistons 12 and 13 pushed by a handle 2. When the user exerts pressure on the handle acting as a lever, the branches of the calliper 3 articulated on the latter press at the same time on the pistons of the master cylinders compressing the liquid which, via two hoses made of plastic 24 and 25 exerts in its turn pressure on the pistons 20 and 28 of the two receiving cylinders 14 and 15 pushing the jaws of the brakes. The receiving cylinders can be mounted and dismounted instantaneously. The filling or recharging with liquid is performed by the valves 17 and 27 of the receiving cylinders by simple suction like a syringe. IMAGE
