Problems solved by technology

[0004] In view of this, the purpose of the present invention is to overcome the defects in the prior art and provide a transmission and an engine. When the temperature of the engine changes, the relative relationship between the main shaft and the auxiliary shaft remains unchanged, and at the same time solve the problems of poor commerciality of shifting and low reliability of gear teeth.

Embodiment Construction

[0018] figure 1 It is a structural schematic diagram of the present invention, as shown in the figure, the transmission in this embodiment includes a housing, a main shaft 1, a counter shaft 2 and a transmission gear set arranged between the main shaft and the counter shaft; one end of the main shaft 1 and One end of the countershaft 2 is axially fixed to the housing on the same side; the housing is an engine case, and the right end (or left end) of the main shaft 1 and the right end (or left end) of the countershaft 2 are axially fixed on the housing, and the left end (or right end) of the main shaft and the left end (or right end) of the auxiliary shaft and the housing are provided with a shifting amount in the axial direction, so as to meet the temperature change of the engine, and one end of the main shaft and one end of the auxiliary shaft. The same side is axially fixed to the casing, so that the relative relationship between the main shaft and the auxiliary shaft remain...

Abstract

The invention discloses a transmission and an engine. The transmission comprises a shell, a main shaft, an auxiliary shaft and a drive gear set arranged between the main shaft and the auxiliary shaft.One end of the main shaft and one end of the auxiliary shaft are axially fixed to the shell in a same side manner. One end of the main shaft and one end of the auxiliary shaft are axially fixed to the shell in the same side manner, and displacement is reserved between the other ends of the main shaft and the auxiliary shaft and the shell in the axial direction so as to meet the temperature changeof the engine. By means of the structure, the relative relation of the main shaft and the auxiliary shaft is unchanged, locating of a shifting fork is accurate, the actual engagement length of gear teeth is unchanged, and the gear shift commodity and gear tooth reliability of the engine are improved.

Description

technical field [0001] The invention relates to the field of engines, in particular to a transmission and an engine. Background technique [0002] The transmission of two-wheeled and three-wheeled motorcycles is generally integrated in the engine case, which is called the transmission mechanism (also called the main and auxiliary shaft transmission); in order to avoid interference, when designing the main and auxiliary shafts, it is necessary to reserve Axial clearance between bodies, easy to install main and auxiliary shafts. At the same time, there is a certain amount of axial movement in the free state of the main and auxiliary shafts to meet the expansion or contraction of the casing when the engine temperature changes; the axial movement will cause incorrect positioning of the shift fork and The actual gear meshing width of each gear tooth changes, which in turn leads to problems such as poor commerciality of gear shifting and low reliability of gear teeth. [0003] T...
