  • Publication number: 20200132132
    Abstract: An electric vehicle transmission method includes the steps of: detecting a gear-shift command; judging if the gear-shift command is in conflict, if it is in conflict, then it returns back to the step of detecting the gear-shift command while if it is not in conflict, then proceeds to the next step; proceeding to a synchronized position, a dispelling fork drives a synchronizer to make the synchronizer move from the original gear position to a synchronized position, and the dispelling fork does not move within a synchronized time; and proceeding to a target position, the dispelling fork drives the synchronizer again to make the synchronizer move to the target gear position.

  • Publication number: 20200072351
    Abstract: A parking mechanism used in gearbox, including a ratchet pawl and a cam set for driving the ratchet pawl. The cam set includes a shaft, a first and a second cam pivotally engaged with the shaft, wherein the shaft drives the first cam and the second cam to rotate, so as to drive the ratchet pawl to engage with a gear wheel that is pivotally engaged with a shaft member and to stop the shaft member. The cam set as a driving means simplifies the parking mechanism and is easy to be manufactured and disassembled.

  • Publication number: 20190120328
    Abstract: A dual-shaft clutch varying speed device includes a drive unit, an input shaft, an output shaft, a housing, at least an odd-numbered clutch unit and at least an even-numbered clutch unit. The input shaft having an input gear is coupled with the drive unit. The output shaft, having an end thereof penetrate through the input shaft and the drive unit, has at least an odd-numbered output gear and at least an even-numbered output gear. The housing has a housing gear. The at least one odd-numbered clutch unit being furnished at the inner part of the housing has an odd-numbered clutch shaft and an odd-numbered clutch gear which is meshed with the odd-numbered output gear. The at least one odd-numbered clutch unit has an even-numbered clutch shaft and an even-numbered clutch gear which is meshed with the even-numbered output gear.

  • Patent number: 10054224
    Abstract: A parking brake includes transmission shaft, park gear and parking assembly. The park gear is connected to the transmission shaft. The parking assembly includes holder and engagement mechanisms. The holder on the transmission shaft is slidable in axial direction of the transmission shaft. The engagement mechanism includes engagement body and elastic member. The engagement body is furnished on the holder and slidable in a radial direction of the transmission shaft. The elastic members are connected to the holder and located between the holder and the engagement bodies. The engagement bodies protrude from a surface of the holder. When the parking assembly is moved toward the park gear, and some of the engagement bodies are pressed and moved with respect to the holder, the park gear is engaged with some of the plurality of engagement mechanisms not moved with respect to the holder.
