Bicycle derailleur

A bicycle derailleur is basically provided with a base member, a movable member, a coupling structure and an attachment member. The base member is configured to be mounted to a bicycle. The base member has an inner wire guide. The inner wire guide has an inlet portion and an outlet portion. The movable member supports a chain guide. The coupling structure movably couples the movable member to the base member so that the movable member is selectively movable relative to the base member. The attachment member is detachably and/or rotatably attached to the outlet portion of the inner wire guide.

A bicycle derailleur is basically provided with a base member, a chain guide, a linkage assembly and a first adjusting member. The chain guide is pivotally supported with respect to the base member between a retracted and an extended position. The linkage assembly includes a first link coupled to the base member about a first pivot axis and coupled to the chain guide about a second pivot axis. The linkage assembly includes a second link coupling the base member to the chain guide. The second link is farther from the bicycle frame than the first link when the base member is mounted to the bicycle frame. The first adjusting member is movably attached to the first link. The first adjusting member is configured to contact one of the base member and the chain guide to restrict movement of the chain guide at one of the retracted and extended positions.

The selected chain guide unit has a chain guide for guiding a bicycle chain and a support mechanism moveably supporting the chain guide relative to the fixing member. The selected chain guide unit is one of a plurality of different configurations of chain guide units. The motor unit is configured to be selectively attached to the selected chain guide unit to move the chain guide. The motor unit is configured to be mounted to each of the plurality of configurations of chain guide units.

Hydraulic control system with ETRS for a continuously variable transmission

A hydraulic control system for a CVT includes a pressure regulator subsystem, a ratio control subsystem, a torque converter control (TCC) subsystem, a clutch control subsystem, an electronic transmission range selection subsystem, and is enabled for automatic engine start/stop (ESS) functionality.

Device and method for driving shift lever

Disclosed are device and method for driving a shift lever. The device may include a control unit that sets a travel distance of the shift lever when the shift lever is manipulated to a predetermined shift stage to be different than a reference travel distance of the shift lever, which is a travel distance of the shift lever when the shift lever is manipulated to shift stages other than the predetermined shift stage. The device may further include a driving unit which restricts a travel of the shift lever or moves the shift lever depending on a setting of the control unit.

Hydraulic control circuit and its control method

In a hydraulic control circuit including a solenoid valve, whose change responsiveness in an actual pressure with respect to a change in an instructional pressure deteriorates when the instructional pressure enters a dead band region on a lower pressure side than a dead band threshold, for adjusting a hydraulic pressure supplied to a hydraulic device operated by the hydraulic pressure based on the instructional pressure, the instructional pressure is increased in a stepwise manner to a charge pressure higher than the dead band threshold, when the instructional pressure is set in the dead band region and the instructional pressure increases within the dead band region to such an extent that a speed ratio does not change. Then, a lower limit of the instructional pressure is set to the dead band threshold, and use of the dead band region is prohibited for a certain period of time.

Hydraulically actuated continuously variable transmission

A hydraulically actuated continuously variable transmission (1) with two pulleys (5, 6), a drive belt (4) in frictional contact with these pulleys (5, 6) and a control device that includes at least two pressure chambers (8, 9) that are both associated with one pulley (6) and that are arranged such that a clamping force (Fs) that is exerted on the drive belt (4) by that one pulley (6) during operation of the transmission 1 is determined by the difference between the two pressures (Pline, Pcomp) that are respectively exerted therein and that are respectively actively controlled by a respective pressure control valve (13; 40) of the control device.

Transmission system having temperature based input control

A transmission system is disclosed for use with an engine. The transmission system may have a plurality of gear sets, an input member configured to be powered by the engine and to drive the plurality of gear sets, an output member driven by the plurality of gear sets, and at least one clutch configured to selectively engage select gears of the plurality of gear sets. The transmission system may also have a controller in communication with the engine. The controller may be configured to generate an estimated temperature of the at least one clutch. The controller may further be configured to selectively derate the engine based on the estimated temperature.
