Problems solved by technology

[0003] It can be seen from the above that all forward gears, reverse gears and synchronizers in the transmission are arranged on the input shaft and the intermediate shaft, so that the axial length of the input shaft and the intermediate shaft is relatively long, resulting in the The deflection is relatively low, and it is easy to deform the shaft, which can not only reduce the service life of the shaft, but also cause bad noise when the transmission is working

Abstract

The embodiment of the invention discloses a mechanical synchronous transmission, and relates to the technical field of vehicle transmission. The mechanical synchronous transmission is invented to reduce the noise generated by the transmission in a working state. The mechanical synchronous transmission comprises a transmission box which is internally provided with a differential mechanism, a gear, and an input shaft, a first middle shaft and a second middle shaft in parallel. The gear comprises a front shift moveable wheel and a front shift fixed wheel which are engaged with each other, a reverse shift moveable wheel and a reverse shift fixed wheel which are engaged with each other, an output wheel and a middle wheel. The input shaft and the first middle shaft are provided with the front shift moveable wheel and the front shift fixed wheel, and a shaft on one side of the front shift moveable wheel is provided with a synchronizer. The first middle shaft is provided with the output wheel which is engaged constantly with a gear ring of the differential mechanism, and the first middle shaft is further provided with the reverse shift fixed wheel. The second middle shaft is provided with a middle wheel which is engaged constantly with the front shift fixed wheel on the output shaft, and the second middle shaft is further provided with the reverse shift moveable wheel. A shaft on one side of the reverse shift moveable wheel is provided with a synchronizer.

Description

technical field [0001] The invention relates to the technical field of vehicle transmission, in particular to a mechanical synchronous transmission. Background technique [0002] At present, the traditional mechanical synchronous transmission has five forward gears and one reverse gear (R gear). Specifically, this kind of mechanical synchronous transmission can be, for example, the following structure: it includes a gearbox, and a differential, an input shaft, an intermediate shaft and a reverse gear shaft parallel to each other are arranged in the gearbox, wherein both the input shaft and the intermediate shaft are The set is equipped with gears, and the gears include five idle wheels and five fixed wheels, and the five active wheels mesh with the five fixed wheels to form five forward gear sets with different transmission ratios; The gears also include the movable wheel of the reverse gear and the fixed wheel of the reverse gear, and an idler gear is engaged between the m...
