摘要： A hydraulic connector for removably joining together a first and a second piece of a tube of a hydraulic system of a bicycle includes a tubular sleeve extending along a middle axis, a first area of the tubular sleeve to be fixed to the first piece of tube, and a second area of the tubular sleeve to be fixed to the second piece of tube. The hydraulic connector also includes a first tubular segment and a second tubular segment. Both of the tubular segments extend along the middle axis and have an internal diameter adapted for receiving the pieces of tube to be joined. The hydraulic connector also includes a first hollow screw, in screwing engagement with the first area of the tubular sleeve, and the first tubular segment is formed in the first hollow screw. The tubular sleeve and the first hollow screw, in every section thereof along the middle axis, have an internal diameter equal to or greater than the internal diameter of the tubular segments.

摘要： A lever system using a linkage assembly creates linear movement from a rotational movement of a lever. The lever system may be arranged as a grip assembly to activate a braking system of a vehicle. The linkage assembly may include a slide linkage, a bearing linkage, and a pivot linkage such that the lever may cause an end of the bearing linkage and an end of the pivot linkage to move toward the slide linkage, which causes the slide linkage to move in a linear direction. The grip assembly may have a lever that is pivotally connected with a housing of the grip assembly at a predetermined distance and with a contact region to prevent rotational movement in one direction while allowing rotational movement in the opposite direction. Further, the grip assembly may include a bearing linkage that is pivotally connected to the lever.

摘要： A bicycle operating device includes a housing, a control unit, a speed shifting unit and a fluid pressure generating assembly. The housing includes a grip portion. The grip portion has a first end portion and a second end portion. The control unit is rotatably connected to the housing. The speed shifting unit is disposed on the housing. The speed shifting unit includes a reel, a shaft and at least one lever. The fluid pressure generating assembly includes a cylinder and a piston assembly. The control unit drives the piston assembly to move relative to the cylinder to generate a control fluid pressure, the cylinder is disposed on the housing and adjacent to the first end portion, the reservoir is located above the cylinder, and the piston assembly is movable along a cylinder axis of the cylinder.

摘要： A hydraulic operating device is provided for a human-powered vehicle. The hydraulic operating device basically includes a base, an operating member and a handlebar mounting structure. The base includes a cylinder bore defining a cylinder axis. The operating member is pivotally coupled to the base about a pivot axis between a rest position and an operated position. The handlebar mounting structure is coupled to the base. The handlebar mounting structure defines a handlebar mounting axis that extends linearly along a handlebar in a mounted state. The cylinder axis is inclined towards the handlebar mounting axis as the cylinder bore extends away from the pivot axis as viewed in a pivot axis direction parallel to the pivot axis. The pivot axis is located in an area between the cylinder axis and the handlebar mounting axis as viewed in the pivot axis direction.

摘要： A vehicle is driven by muscle power and/or an electric motor and includes a brake assistance device for a hydraulic brake system. The brake assistance device has a sensor with a first piston, a compensation volume with a second piston and a pretensioning element, a 2/2-way valve, a brake piston, and an actuator. The pretensioning element is configured to exert a pressure onto the second piston and thus onto a hydraulic fluid of the hydraulic brake system. The actuator is configured to move the second piston selectively in a first direction or in a second direction oriented opposite the first direction.

摘要： The disclosure provides an anti-lock brake device including an oil pressure tank, a valve, and a movable component. The oil pressure tank has an accommodation space, an oil inlet channel, and an oil outlet channel connected to the accommodation space. The valve is slidably located in the oil inlet channel and for sealing or opening an oil inlet of the oil inlet channel. The movable component is located in the accommodation space and has a connecting channel corresponding to the oil inlet and an oil outlet of the oil outlet channel. When the movable component is slid to a depressurized position, the movable component is moved away from the valve for sealing the oil inlet, a first volume is produced between the connecting channel and the oil inlet, and a second volume, smaller than the first volume, is removed from between the connecting channel and the oil outlet.

摘要： Complete or predominant use of regenerative braking in electric motorcycles rather than hydraulic braking may lead to brake discs and pads that are below an optimum operating temperature. To reduce the risk of accident, an indicator warns motorcycle riders that the brakes are below optimum operating temperature. With this knowledge, riders are prepared to apply extra braking force when slowing down, particularly in an emergency situation. Relative application of the regenerative brake and hydraulic brakes may be controlled to raise the temperature of the brakes so that they are primed.

摘要： A tool for a brake system may comprise a tool body configured to fit within a recess of a body of the caliper assembly. The tool body comprises a first section; the first side comprises a raised surface; the second side comprises a base surface. The first section is to be inserted into the recess of the caliper assembly; in a first mode the first piston set is blocked by the raised surface and the second piston set is unblocked; in a second mode the second piston set is blocked by the raised surface and the first piston set is unblocked. The tool body comprises a second section to be inserted into the recess of the caliper assembly; in a third mode both the first piston set and the second piston set are blocked from movement. A brake system may comprise an improved master cylinder assembly.
