Engine for tricycle

Abstract

The invention discloses an engine for a tricycle, which comprises an engine case body, wherein a crankshaft and a main shaft are arranged in the engine case body, the main shaft is parallel with the axis of the crankshaft and is connected with the crankshaft by a clutch device, an auxiliary shaft is arranged in the engine case body, and the axis of the auxiliary shaft and the axis of the main shaft can form an included angle of 90 degrees; the upper periphery of the main shaft is provided with an driving bevel gear, the auxiliary shaft is provided with a driven bevel gear, the driving bevel gear and the driven bevel gear are matched and meshed with each other, and the driving bevel gear can drive the driven bevel gear to rotate, and further drive the auxiliary shaft to rotate. The engine provided by the invention is not provided with a shift mechanism, which can reduce the number of used parts and largely reduce the costs of the engine; based on the simplified inner parts of the engine, the engine mechanism can be simplified, the mechanical loss of the engine can be lessened, the failure rate of the engine can be decreased, the mechanical noise of the engine can be reduced, the engine assembly can be simplified, the operation can be more simple and convenient and the maintenance difficulty can be lowered.

Description

technical field [0001] The invention relates to a power device for motor vehicle (tricycle), especially an engine in the power device for the tricycle. Background technique [0002] Tricycles are often used in high-load and harsh conditions. Most of the owners use them to carry passengers and goods, and they are overloaded with goods, which makes their power devices prone to failure, especially the engine is more prone to wear and damage. . The motor of the prior art tricycle, what the existing tricycle engine uses is the two-wheeled motorcycle engine, in order to make the two-wheeled motorcycle engine can meet the use requirements, it is necessary to change the original chain drive form into a shaft drive form, in addition In addition, it is also necessary to set forward and reverse gears on the tricycle. Therefore, it is necessary to add a reverse gear to the output shaft of the engine, such as figure 1 As shown, the original structure of the engine remains unchanged,...

AI Technical Summary

Problems solved by technology

[0002] Tricycles are often used in high-load and harsh conditions. Most of the owners use them to carry passengers and goods, and they are overloaded with goods, which makes their power devices prone to failure, especially the engine is more prone to wear and damage.

[0003] 1. In addition to driving the two-wheeler engine, the tricycle also needs other auxiliary mechanisms to keep the tricycle in normal use, so additional costs are required,

[0004] 2. The increase of the mechanism leads to complex engine assembly,

[0005] 3. Due to the large axial thrust of the bevel gear during operation, the connection thread of the reverse gear is often damaged, which leads to an increase in the engine failure rate and an increase in maintenance costs.

[0006] 4. The increase of the shifting mechanism makes the operation of the engine with the shifting mechanism more complicated during use, which is not conducive to the simplification of the control
