摘要： A bicycle wheel brake consisting of a pair of opposed friction blocks carried by respective levers pivoted, either directly or through a support, to the bicycle frame, so as to be controllable against the action of spring members to lock the blocks against the wheel rim. Each lever is pivoted at one side of the wheel so as to move on a plane substantially parallel to the plane tangential to the wheel.

摘要： The invention provides a center-pull calliper brake for a bicycle or the like in which the callipers are hinged about respective axes which are inclined with respect to the median plane of the wheel rim in such a way as to diverge when considered along the direction of movement of the wheel during forward travel of the vehicle. This gives a self-applying braking effect which considerably increases the safety of the bicycle.

摘要： A bicycle wheel rim brake comprises a pair of extensible and retractable brake members mounted in bicycle frame members which straddle the wheel rim. Each brake member is symmetrical about the longitudinal axis of its frame member and is slidably mounted in an opening formed in a support for movements toward and away from the rim. A cover is carried by each support and overlies the associated opening. Springs acting between the covers and the brake members bias the latter away from the rim and hold the covers in place.

摘要： Caliper type bicycle brakes for the front and rear wheel are actuated simultaneously by a single actuator assembly mounted adjacent the handlebar. Hydraulic fluid under pressure is delivered to the brakes through two self-contained hydraulic circuits, one for the front brake and one for the rear brake. The brake system includes a device for applying a greater braking force at the front wheel than at the rear wheel. In an alternate embodiment the brake system is actuated by the chain drive system of the bicycle. Improved brake shoe elements and a device for wiping water from the wheel rim for enhanced wet weather braking are also disclosed.

摘要： A bicycle brake including a first lever and a second lever is provided. A roller for mutual coupling of the first lever and second lever is pivoted to one of said first lever and second lever and is in rolling contact with a surface portion of the other between said first lever and second lever. The surface portion has a profile defined by a curve that passes by a predetermined number of points of the roller. Each of the points are defined as function of the position taken by the roller during a respective rotation of the roller about a first rotation axis (X1) of the first lever by a respective predetermined angle of rotation and about a second rotation axis (X2) of the second lever by a respective angle substantially equal to said respective predetermined angle of rotation.

摘要： A bicycle brake device comprises a friction member, a base member, a link structure, and a piston. The base member includes a hydraulic cylinder. The link structure is configured to couple the friction member to the base member so as to move the friction member relative to the base member between a rest position and a braking position. The piston is movable in the hydraulic cylinder in a movement direction and configured to push the link structure to move the friction member from the rest position toward the braking position.

摘要： A bicycle brake device comprises a friction member, a base member, and a piston. The base member includes a hydraulic cylinder. The piston is movable in the hydraulic cylinder in a movement direction so as to move the friction member toward a rotatable member. The piston is at least partially provided in a frame area defined by an outline of a bicycle frame when viewed from the movement direction in an attachment state where the base member is attached to the bicycle frame.

摘要： A bicycle rim brake is basically provided with first and second brake arms and a hydraulic actuation device. The first brake arm has a first coupling portion, a first actuated portion and a first mounting portion. The first coupling portion includes a first mounting fastener defining a first pivot axis of the first brake arm. The first mounting portion mounts a first friction member. The second brake arm has a second coupling portion, a second actuated portion and a second mounting portion. The second coupling portion includes a second mounting fastener defining a second pivot axis of the first brake arm. The second mounting portion mounts a second friction member. The hydraulic actuation device includes first and second pistons movably disposed in a cylinder housing and operatively coupled to the first and second actuated portions on the first and second brake arms, respectively.
