AI Technical Summary

Technical Problem

The existing gearboxes are noisy, large in size and heavy in weight, especially when driven by motors, which affect the battery life.

Method used

A gear box with an output shaft clutch is designed. Through the coordination of the output shaft piston with the driven gear and the rear output shaft internal teeth, the coupling transmission or disengagement between the front output shaft and the rear output shaft is achieved, reducing the volume and weight of the clutch.

Benefits of technology

The gearbox is smaller in size and lighter in weight, and can transmit large torque, reduce noise and vibration, and improve structure simplicity and work reliability.

Abstract

The present invention relates to a gearbox with an output shaft clutch, comprising an input shaft and an output shaft, wherein the output shaft clutch is used to control the coupling transmission or disengagement between the front output shaft and the rear output shaft. When the output shaft clutch is disengaged and only the motor provides power, the transmission mechanism and hydraulic system of other parts of the gearbox do not work, which greatly reduces noise and vibration; when the output shaft clutch is engaged, the motor and the diesel engine can form a dual-power unit to increase the power of the unit. In order to solve at least one of the technical problems of the gearbox in the prior art, such as high noise, large volume, and heavy weight, the present invention proposes an output shaft clutch, a gearbox, and a vehicle. Through the segmented structural design of the output shaft of the gearbox, the output shaft clutch is used to realize the coupling transmission or disengagement between the front output shaft and the rear output shaft of the gearbox.
