Fuel gearbox assembly with synchronizer

Abstract

The invention discloses a fuel gearbox assembly with a synchronizer. An input shaft, an output shaft and a reverse idle gear shaft are arranged in a gearbox shell. The input shaft is sleeved with a forward gear driving gear, the synchronizer and a reverse gear driving gear, and the synchronizer is in slide connection with the input shaft. The output shaft is fixedly sleeved with a main speed reducing gear, the reverse idle gear shaft is fixedly provided with a first gear meshed with the reverse gear driving gear and a second gear meshed with the main speed reducing gear, and the main speed reducing gear is in meshing transmission with the forward gear driving gear. An engine pulling and locking bracket, a shift pulling and locking bracket and an engine installation plate are arranged on the outer wall of the gearbox shell. According to the fuel gearbox assembly, the synchronizer is applied to a gearbox assembly of a tricycle and an improvement is made according to the features of the tricycle, so the technical problem that gears in the tricycle gearbox assembly are damaged badly for a long time is effectively solved; the structural layout of the two pulling and locking brackets and the engine installation plate is optimized, so the overall structure of the fuel gearbox assembly can be more compact and reasonable.

Description

technical field [0001] The invention belongs to the technical field of mechanical structures, and in particular relates to a vehicle transmission assembly structure, which is mainly used for tricycles. Background technique [0002] Tricycles are divided into manpower tricycles and fuel tricycles. In the existing transmission assembly, gears are shifted through hard gears, which can easily damage the gears in the transmission assembly, resulting in a product return rate of up to 30%, which seriously affects product quality. Moreover, there is an unreasonable layout on the outer wall of the transmission assembly, which affects the compactness of the overall structure. Contents of the invention [0003] The object of the present invention is to provide a fuel transmission assembly with a synchronizer, which can improve product quality and avoid gear damage during gear shifting by optimizing the structure. [0004] For this reason, the technical solution adopted by the presen...
