Problems solved by technology

One is to use the combination and disengagement of friction discs to realize power transmission and cut-off. This method contains friction pair elements, which has the advantages of smooth and smooth combination, but requires complex operating mechanisms and actuators to control the friction pair elements. Compression and loosening have the characteristics of complex structure and high cost
The other is to use the engagement and disengagement of the meshing elements to realize power transmission and cutting. This method has the advantages of large load capacity, small size and simple structure, but the meshing process of the meshing elements is easily affected by the initial position of the meshing elements. , if the initial position of the meshing element is in a position that is not conducive to the engagement of the meshing element and participating in the meshing, it will not be guaranteed that one switching operation will complete the meshing of the meshing element, resulting in unsuccessful power switching of the power selection device, and the initial position of the meshing element is usually Random, so the power switching success rate of the power selection device with this structure is lower than that of the friction disc power switching device, and the reliability is low

Embodiment Construction

[0016] refer to Figure 1 to Figure 6 The invention is further elaborated, the upper, middle and lower axes are distributed in the box body 2, the motor input shaft 10 and the motor input shaft gear 8 are arranged at the upper axis, and the motor input shaft gear 8 is fixed on the motor input shaft 10, and the motor input shaft gear 8 is fixed on the motor input shaft 10. The shaft 10 rotates together; the central axis is provided with an intermediate gear shaft 6, an intermediate shaft gear 7 and a one-way overrunning clutch 9. The intermediate shaft gear 7 is fixed on the intermediate gear shaft 6 and rotates together with the intermediate gear shaft 6. The one-way overrunning clutch 9 The inner star wheel 17 of the one-way overrunning clutch and the countershaft gear 7 are fixed together and rotate together with the countershaft gear 7. The countershaft gear 7 meshes with the motor input shaft gear 8, and the one-way overrunning in the one-way overrunning clutch 9 The clutc...

Abstract

The invention relates to the technical field of transportation machinery, in particular to a power selection device with a manually operated dial shaft, which solves the problem of low success rate of power selection switching of dual-power transportation equipment, including a box body, gears, gear shafts, two-way clutches, One-way overrunning clutch, flexible shaft and spring, the present invention is provided with two-way clutch and one-way overrunning clutch inside the power selection device, manually operates the two-way clutch to select the path of power transmission, once the two-way clutch meshing difficulty occurs in the switching process, it can be set by setting Manually and remotely operate the one-way overrunning clutch on the flexible shaft outside the box, change the initial relative position of the internal meshing elements of the two-way clutch, and improve the success rate of the re-switching operation of the two-way clutch. Under the action of the internal and external disengagement, it does not affect the normal power transmission.

Description

technical field [0001] The invention relates to the technical field of transportation machinery, in particular to a power selection device with a manually operated dial shaft. The manual remote operated dial shaft mechanism can remotely dial the gear shaft in the transmission box to rotate, and is used to increase the time when the transmission gear in the transmission box is switched. reliability. Background technique [0002] In recent years, in the field of transportation machinery, a kind of transportation equipment driven by two power sources in time-sharing has emerged. The two power sources are usually diesel engines and motors. This kind of equipment can be driven by diesel engines. The motor provides power to drive the travel transmission system of the equipment. This kind of equipment must have a power selection problem. When the driver selects the diesel engine drive mode, the power output by the diesel engine is input into the walking transmission system of the ...
