Problems solved by technology

[0002] Tricycles are divided into manpower tricycles and fuel tricycles. In the existing transmissions, the gears are hard-shifted through the gears, which can easily damage the gears in the transmission, resulting in a product return rate of up to 30%, which seriously affects the product quality. There is an unreasonable layout, which affects the compactness of the overall structure
[0003] In addition, the reverse light switch in the traditional structure is located at the installation position of the shift handle. The reverse light switch is controlled by operating the shift handle. The sensitivity and accuracy are not high, and it is easy to cause the reverse light to not light up after the reverse gear. , or the phenomenon that the reverse light is on when in the forward gear

Abstract

The invention discloses a tricycle transmission. An input shaft, an output shaft and a reverse gear idler shaft are arranged in a transmission housing, the input shaft is sleeved with a forward gear driving gear, a synchronizer and a reverse gear driving gear, the synchronizer and the input shaft are connected in a sliding mode, the output shaft is fixedly sleeved with a main speed reduction gear, a first gear meshed with the reverse gear driving gear and a second gear meshed with the main speed reduction gear are fixedly arranged on the reverse gear idler shaft, and the main speed reduction gear is in meshed transmission with the forward gear driving gear; an engine zipper support, a gear shift zipper support, a reverse gear tricycle lamp switch and an engine mounting disk are installed on the outer wall of the transmission housing. The synchronizer is applied into the transmission of a tricycle, improvements are made according to the characteristics of the tricycle, and thus the technical problem that for a long time, gears in a tricycle transmission are damaged severely is effectively solved. The structural layout of parts outside the housing is optimized, and the overall structure of the tricycle transmission is made 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 structure, which is mainly used in small vehicles such as tricycles. Background technique [0002] Tricycles are divided into manpower tricycles and fuel tricycles. In the existing transmissions, the gears are hard-shifted through the gears, which can easily damage the gears in the transmission, resulting in a product return rate of up to 30%, which seriously affects the product quality. There is an unreasonable layout, which affects the compactness of the overall structure. [0003] In addition, the reverse light switch in the traditional structure is located at the installation position of the shift handle. The reverse light switch is controlled by operating the shift handle. The sensitivity and accuracy are not high, and it is easy to cause the reverse light to not light up after the reverse gear. , or the phenomenon that the r...
