A three-stage speed-change mechanism includes a casing in an interior of which a drive assembly, an input assembly, and an output assembly are arranged. The input assembly includes a transmission shaft driven by the drive wheel. An initial transmission wheel is mounted no a middle section of the transmission shaft. A first speed-change assembly and a second speed-change assembly are respectively arranged on two sides of the initial transmission wheel. The output assembly includes an output shaft, which is provided with an initial driven wheel and first and second speed-change wheels respectively mating the initial transmission wheel and the first and second speed-change assemblies. The initial driven wheel and the first speed-change wheel are respectively mounted by a first one-way bearing and a second one-way bearing on the output shaft. As such, a three-stage speed-change function is realized.

Abstract:
The present invention relates to a transmission for a motor, and more particularly, to a transmission for a motor, which optimizes a transmission for outputting a rotational force only in one direction at different shifting ratios according to forward/reverse rotation directions of a rotational shaft of the motor while enabling a reverse input, accurately transmits the rotational force without slippage and has durability even upon use thereof for a long period of time. Accordingly, the transmission improves reliability and shifting accuracy and maximizes marketability and market competitiveness.
Abstract:
A bicycle drive unit has a transmission and a motor that transmits torque to the transmission. The transmission includes first and second input side rotating bodies, first and second output side rotating bodies, an output unit and a switching mechanism. The first and second output side rotating bodies are coupled to the first and second input side rotating bodies, respectively. The switching mechanism switches between a first state in which rotation of the first input side rotating body is transmitted to the output unit, and a second state in which rotation of the second input side rotating body is transmitted to the output unit. Only torque of the motor is transmitted from the first and second input side rotating bodies to the output unit, while torque outputted from the output unit merges with a manual drive force in a drive force transmission path from the output unit to a wheel.

A transmission for a vehicle may include a first input shaft continuously receiving torque from a power source and having a first input transfer gear thereon, a second input shaft selectively receiving torque from the power source through a clutch and having a second input transfer gear thereon, a coupling member allowing or restricting rotation of the first input transfer gear relative to the first input shaft, a first countershaft and a second countershaft each having an output transfer gear to be engaged with the first input transfer gear and the second input transfer gear, and coupling devices selectively coupling the output transfer gears to corresponding countershafts and allowing torque from the power source to be transmitted to a desired shift gear by coupling output transfer gears connected to the desired shift gear in the output transfer gears to a corresponding countershaft in advance or after synchronization in shifting.
Abstract:
A multistage transmission device includes a plurality of driving gears provided in a countershaft, a plurality of driven gears meshing with the driving gears, respectively, dog rings that switch mechanical connection or disconnection between the drive shaft and each of the driven gears, and one-way clutches arranged between the countershaft and the driving gears. The one-way clutches transmit rotation of the countershaft to the driving gears when the rotation of the countershaft is faster than the rotation of the driving gears.
Abstract:
A vehicle transmission device provides power transmission and speed switch for the operation demands of the vehicle to advance. The transmission device includes a driving shaft or an input shaft connected with a power source. The input shaft is provided with an input gear set and spring-like members disposed inside the input gear set. An output gear set is provided to mesh with the input gear set. A transmission control mechanism is disposed on the input shaft for the input gear set to transmit a power to the output gear set and an output shaft to output the power to drive the vehicle. The present invention can enhance the power, torsion and speed of the vehicle.
Abstract:
A shift control apparatus for an automatic transmission includes a controller. The controller is configured to control the automatic transmission. The automatic transmission includes a first input shaft, a second input shaft, an output shaft, a first clutch, a second clutch, and gear trains. In a case where a standby shift stage does not lie between a predetermined current shift stage and a target shift stage, the controller controls the first clutch to be disengaged and the second clutch to be engaged, and then controls a synchronizing device among synchronizing devices for the predetermined current shift stage to be disengaged and a synchronizing device among the synchronizing devices for the target shift stage to be engaged during a disengagement of the first clutch, and then controls the second clutch to be disengaged and the first clutch to be engaged.
Abstract:
A marine transmission includes a synchronizer on a counter rotating shaft to shift into a high speed gear. The synchronizer includes friction surfaces on both sides of the gear body for the high speed gear. The high speed gear mesh is helical and generates axial force that enhances the torque carrying capacity of synchronizing friction surfaces, thereby enabling the shifting into the high speed gear without torque interrupt.
