Abstract:
A tire valve assembly includes a stem and a valve unit. The valve unit includes a movable part and a seal member. When introducing pressurized air into the tire valve assembly, the valve unit moves to a position in the stem to allow the pressurized air to flow into the tire. When the pressurized air is stopped from entering the tire valve assembly, the valve unit is pushed back by the pressure in the tire to seal the inlet so that the pressurized air in the tire does not leak to keep the tire pressure.
Abstract:
A brake pad assembly includes a backing plate, a brake lining and a brake wear indicator. The brake lining is disposed on a front side of the backing plate for engagement with a rotor to be braked. The brake wear indicator is formed of an elastic metallic strip with one end attached to the front side of the backing plate. Moreover, the brake wear indicator is disposed adjacent to the brake lining for engagement with the rotor to be braked once the brake lining is worn out to a predetermined safe thickness, and thereby causing an annoying noise to alert an motorist that the brake pad assembly needs to be replaced.
Abstract:
A cooling device for a rim and a braking system includes a blower set having a frame and two blowers, the frame assembled onto a fork of a bicycle, the two blowers both assembled onto the frame at one side of a rim member, each blower having an air inlet, a receiving room, a fan, an air outlet and a switch unit, the fan rotatably assembled in the receiving room, the receiving room communicating with the air inlet and the air outlet, the switch unit electrically connected to the fan, the air outlet of one blower corresponding to a braking member of the bicycle, the air outlet of another blower corresponding to the rim member.
Abstract:
A bicycle brake disc assembly includes an inner disc, an outer annular disc and a plurality of joint assemblies. The outer annular disc encloses the inner disc. The outer annular disc has a plurality of attachment arms. The inner disc has a plurality of connecting arms. The joint assemblies connect the attachment arms and the connecting arms. Each joint member has a first joint member and a second joint member. The first joint member and the second joint member are riveted together. A buffer groove defined between the first joint member and the second joint member. Each attachment arm and each connecting arm are clipped within the buffer groove. Under this arrangement, the inner disc and the outer annular disc are movable in the buffer groove during baking.
Abstract:
A brake disk assembly includes a main plate clamped between the first and second inner plates. The main plate is movable relative to the first and second inner plates. The contact area between main plate and the first and second inner plates is increased to firmly connect the main plate and the first and second inner plates.
Abstract:
A cooling device for hydraulic braking systems includes a case, a turbine unit, and a ring which is connected to an end of a hub. The case has a thorough hole and a ventilation exit communicating inside and outside of the case is defined on the case. The turbine unit is located in the case and has a fixing hole which communicates with the through hole. The ring is connected to the fixing hole of the turbine unit. The ring drives the turbine unit which generates air flows in the case. The air flows flow to the outside of the case via the ventilation exit to remove the heat of the braking system.
Abstract:
A bicycle hydraulic brake clamp includes a clamp, two piston assemblies and a separation board. The clamp has a first slot defined on the middle thereof so that a brake disk is received therein. A second slot and a third slot are respectively defined in two sides of the clamp. A through hole is defined through the clamp and communicates with the third slot. The separation board is fixedly engaged with the through hole via the first slot by a way of welding. The two piston assemblies are respectively installed in the second and third slots via the first slot. The separation board is securely engaged with the through hole so as not only to prevent the separation board from dropping from the clamp by exterior impact, but also to protect the separation board from being damaged by the exterior impact.
Abstract:
A cooling device for bicycles includes a cooling device and a ring, wherein the cooling device has a positioning hole and multiple recesses are located around the positioning hole. The ring is connected to the hub and multiple protrusions are located on the periphery of the ring. The recesses are located corresponding to the protrusions which are engaged with the recesses to secure the cooling device to the ring.
Abstract:
An uncomplicated bicycle device for fastening a steering tube with a stem tube includes two compression rings and a fastening set. The compression ring is fixed on a stem opening by inserting the lateral surface portion into the stem tube and the protruding portion abutted against the stem opening. The steering tube is inserted into the compression rings. A fastening set includes a star nut placed into the steering tube, a cap covering the stem opening and abutted against the compression ring, a cap bolt for screwing the cap and the star nut together. The present invention only uses the compression rings and the fastening set instead of any thread structure and lock nuts for fastening the steering tube within the stem tube. Thus, the adjuster can quickly calibrate and assemble the steering tube within the stem tube again.
