Abstract:
Brake means for a bicycle having a recessed portion provided on either one of the contact portions between a wheel rim and a brake rubber piece and extending in the direction of the periphery of said rim, the other of the contact portions being provided with at least one projection adapted to be brought into engagement with said recess, the arrangement being such that a wedging action is created when the recess and the projection are pressed with each other to produce a strong braking force. Further, the wheel rim may be provided on its recess or projection with uneveness across the recess or projection so as to facilitate draining of water and prevent the braking effect from being reduced in a rainy weather.
Abstract:
A V-type brake is provided for being assembled on a bicycle, the bicycle including two fork arms and a wheel set which is assembled between the two fork arms, the V-type brake including: two brake swing arms, respectively for being pivotably assembled on the two fork arms toward the wheel set, each said brake swing arm having a connecting portion; two brake pad assemblies, respectively assembled on the two brake swing arms, each said brake pad assembly having an assembling slot, the assembling slot positionably and slidably arranged within the connecting portion. A brake system is further provided, including the V-type brake mentioned above, further including a cable assembly, the cable assembly connected to the two brake swing arms, the cable assembly being operable to drive the two brake swing arms and the two brake pad assemblies to swing toward the wheel set.
Abstract:
A bicycle brake shoe device is provided with a brake pad assembly including right and left members on an inner surface respectively wherein the left member has a cavity, and two grooves on top and bottom of the right and left members respectively; a support including an intermediate hole, two grooved rails on top and bottom of an inner surface respectively, and a threaded hole through a right side; a bolt and nut assembly including a nut in the intermediate hole, and a bolt driven through the nut to fasten the bolt and nut assembly and the support together wherein the brake pad assembly and the support are positioned and the grooves are disposed in the grooved rails respectively; and a screw driven through the threaded hole into a hole of the right member to fasten the support and the brake pad assembly together.
Abstract:
A bicycle rim brake comprises a first brake arm, a second brake arm, and a pivotal cam member. The first brake arm is configured to pivot about a first pivot axis. The first brake arm includes a first mounting portion and a first follower. The second brake arm is configured to pivot about a second pivot axis which is different from the first pivot axis. The second brake arm includes a second mounting portion and a second follower. The pivotal cam member is configured to pivot about a third pivot axis which is different from the first pivot axis and the second pivot axis to guide the first follower and the second follower so that the first brake arm pivots about the first pivot axis and the second brake arm pivots about the second pivot axis.
Abstract:
An adjustable shoe mounting structure for bicycle brake device is disclosed. Users may use the first adjusting member of the adjusting assembly to be turned relative to the second adjusting member of the adjusting assembly. That is, the first adjusting member may be pulled inwardly to turn an angle. The first adjusting member uses the elasticity of the spring to move axially and the brake shoe may be adjusted the angle by matching convex teeth with different heights of the first adjusting member and the second adjusting member. It may achieve the efficiency of adjusting brake shoe. Also, it has simple structure and is easy to operate while adjusting.

Abstract:
A rim for a bicycle includes a radially outer tire-engaging portion, a radially inner spoke-engaging portion, a first sidewall and a second sidewall spaced apart from the first sidewall. A brake track is located on the first and second sidewalls including a plurality of grooves formed therein. Each of the plurality of grooves has a radially innermost point and a radially outermost point, wherein the radially outermost point is circumferentially aft of the radially innermost point relative to a forward circumferential travel direction of the rim.
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 wheel rim with a brake rotor includes a wheel rim having two retaining walls respectively and annularly formed on two lateral sides thereof. An annular groove is annularly defined between the two retaining walls for adapting to retain a tire. The wheel rim has a plurality of support plates spacedly formed on one retaining wall and extending toward a center of the wheel rim to form a hub hole defined therein. The hub hole is axially located at the center of the wheel rim for adapting to assemble with a wheel hub. A brake rotor is concentrically connected with the wheel rim and mounted with the other retaining wall of the wheel rim for adapting to be clamped by a disc brake.
