Planet gear embedded reversing engine with interlocking for multifunctional working vehicle

Abstract

The invention discloses a planet gear embedded reversing engine with interlocking for a multifunctional working vehicle. The planet gear embedded reversing engine comprises an input shaft, an output shaft, a needle roller bearing, an output chain wheel, a bearing, a planet gear, a shell, a planet wheel spindle, a sun wheel and a planet gear seat, wherein the input shaft is connected with the output shaft by the needle roller bearing; the output chain wheel is fixed on the output shaft; the bearing is arranged between the output shaft and the shell; the planet gear is engaged with the planet wheel spindle; the sun wheel is engaged with the input shaft; and the planet gear seat is fixed together with the sun wheel. The planet gear embedded reversing engine with interlocking for the multifunctional working vehicle, disclosed by the invention, has the advantages of safety, comfort, long service life, small size and reasonable structure and is suitable for the multifunctional working vehicles; the reversing speed is 1 / 3 of an advancing speed; and the manufacturing cost of the multifunctional working vehicle is reduced.

Description

technical field [0001] The invention relates to an engine, in particular to an interlocking planetary gear built-in reverse gear engine of a multifunctional work vehicle. Background technique [0002] Now ordinary engines do not have a reverse gear or the deceleration of the reverse gear of the engine is not slow enough (limited by the volume of the engine), resulting in the speed of the multi-tool vehicle moving forward and backward is almost the same, and the speed of the reverse deceleration is not slow enough, which affects driving safety; the reverse gear mechanism of the engine The input shaft and the output shaft are not on the same axis. During driving, when the multi-shaft reverse gear mechanism in the gasoline engine transmits torque to the sprocket, the gasoline engine simultaneously bears the additional torque of the multi-shaft shift mechanism inside, which causes the temperature of the gasoline engine to rise and shorten the service life. shorten, and even affe...

Problems solved by technology

[0002] Now ordinary engines do not have a reverse gear or the deceleration of the reverse gear of the engine is not slow enough (limited by the volume of the engine), resulting in the speed of the multi-tool vehicle moving forward and backward is almost the same, and the deceleration of the reverse is not slow enough, which affects driving safety; the reverse gear mechanism of the engine The input shaft and the output shaft are not on the same axis. During driving, when the multi-shaft reverse gear mechanism in the gasoline engine transmits torque to the sprocket, the gasoline engine simultaneously bears the additional torque of the multi-shaft shift mechanism inside, which causes the temperature of the gasoline engine to rise and shorten the service life. Shortened, even affect the normal operation of the gasoline engine
