Abstract:
A cooling device for a brake clamp includes a cooling device mounted on the hub of the bicycle wheel, a receiving room formed in the cooling device, an air vent defined on the peripheral of the cooling device and communicating with the receiving room, a receiving space formed on the peripheral of the cooling device and located adjacent to the air vent. Therefore, a brake clamp is partially received in the receiving space and the airflow from the air vent blows toward the brake clamp directly and continuously so as to cool the brake clamp.
Abstract:
A sealing device for hydraulic brake lever assembly includes a seat having an oil tank defined therein for receiving oil. The oil tank has a connecting hole defined therein. The oil tank is conically tapered toward the bottom thereof. An elastomer is sealingly received in the oil tank. The elastomer has an U-shaped portion formed therein for providing a resilient force. The elastomer has a movable portion formed therein. A piston assembly is received in the oil tank and connected to the elastomer for actuating the elastomer. At least one oil seal is sleeved on the driving shank for preventing oil leakage. When braking, the piston assembly actuates the U-shaped portion to deform. The movable portion is pushed to pressing oil into the connecting hole. When an oil pressure is decreased, the U-shaped portion restores. The movable portion is pulled backward by the resilient force.
Abstract:
An oil guiding device for hydraulic brake lever assembly having a brake lever includes a seat connected to the brake lever. The seat has an oil reservoir disposed thereon. The oil reservoir has an oil chamber defined therein. An oil guiding base is disposed in the oil chamber. The oil guiding base has an oil inlet and an oil outlet defined therein. An oil guiding unit engages with the oil guiding base. The oil guiding unit has a pipe disposed thereon and an oil hole defined therein. The pipe and the oil hole are communicated with the oil outlet and the oil inlet respectively. A cover panel engages with the oil reservoir. The pipe sucks up the hydraulic oil gathered in the oil chamber and supplies the hydraulic oil through the oil outlet; the returned hydraulic oil flows into the oil chamber through the oil inlet.
Abstract:
A tube structure for bicycle cable includes a rigid metallic member spirally wound into a tubular body. The tubular body has a channel centrally defined therein and axially extending therethrough for adapting to be passed through by a bicycle brake cable. A flexible metallic member is connected with the rigid metallic member and is spirally disposed along a length of the rigid metallic member. When the tubular body is impacted with an external force, the rigid metallic member provides an enhanced rigidity to the tubular body for preventing a deformation of the tubular body. The flexible metallic member and the rigid metallic member are alternately arranged so as to allow the tubular body to be bendable and have a sufficient ductility.

Abstract:
A holder for hydraulic brake assembly includes a holder. The holder has one end thrust by a pushing mechanism and another end connected to a brake shoe. The holder has a skirt formed on one end thereof and outwardly extending therefrom to define a receiving space in between the skirt. The pushing mechanism is selectively received in the receiving space in the skirt. The skirt is provided for stably connecting to the pushing mechanism such that the pushing mechanism is steady thrust with the holder to provide a stable brake effect and prevent wear from an unstable contact.
Abstract:
A hydraulic brake device includes a carrier body. The carrier body is integrally molded. The carrier body has at least one assembling portion disposed thereon for assembling purpose. The carrier body has at least one connecting portion respectively extending from the at least one assembling portion. At least one hydraulic brake assembly movably is mounted on the at least one connecting portion of the carrier body. The carrier body with the at least one brake assembly are adapted to assemble with a bicycle for providing a stable assembling effect, a high structural strength, and lightweight effect.
Abstract:
A hydraulic brake lever assembly includes a master cylinder, a master piston, and a floating piston. Both of the master piston and the floating piston are sealingly and movably received in the master cylinder. The master piston has a passage diametrically defined therein and extending therethrough for receiving a bias mechanism. The floating piston has a through hole for coaxially and sealingly receiving the master piston. The floating piston has two raceways radially and symmetrically extending from the through hole therein. The bias mechanism is movably disposed between the two raceways. Each raceway has a trough defined in a bottom thereof. The bias mechanism moves along the troughs and the raceways to provide the effort of multi-stage movement and different braking feel.
