Problems solved by technology

[0004] The layout of the engine and the clutch of the horizontal power system of the above-mentioned patent is the layout of most existing three-wheeled motorcycle engines. , will lead to increased cost, low matching accuracy, large space occupation, unreliable work and other defects
And the engine of above-mentioned arrangement also has the defect that fuel consumption is high and exhaust emission is big, has increased burden for user, also causes bigger pollution to environment
[0005] Moreover, when there is a problem with the heat engine (the engine in the above-mentioned patent), especially when there is a problem with the crankshaft or the clutch part, it is necessary to disassemble the speed change mechanism, reversing mechanism, bevel gear pair, etc. connected thereafter before repairing. Inconvenient and time-consuming maintenance, high maintenance costs
There is also the defect of poor heat dissipation

Embodiment 1

[0027] Embodiment 1: as figure 1 As shown, a single-cylinder engine for a three-wheeled motorcycle includes a heat engine 1 and a clutch 3. The crankshaft 2 of the heat engine 1 is arranged longitudinally, and the output end of the crankshaft 2 is located at the front end.

[0028] Using the single-cylinder engine set in this embodiment, the installation of the heat engine on the vehicle frame is rotated by 90° to realize the longitudinal output of the crankshaft 2 of the heat engine 1. In this way, the transmission efficiency of the single-cylinder engine can be improved, and the engine’s load can be reduced. Fuel consumption and reduced engine emissions.

[0029] Wherein, in order to realize that the engine can transmit power to the rear axle, the power of the engine needs to be transmitted to the rear end of the heat engine 1 for output. In this embodiment, the output end of the crankshaft is connected to the input end of the clutch through the primary transmission gear. ,...

Embodiment 2

[0036] Embodiment 2: as figure 2 As shown, a three-wheeled motorcycle engine includes a heat engine 1 and a clutch 3. The crankshaft 2 of the heat engine 1 is arranged longitudinally. connected, the output end of the clutch 3 is output from the rear end of the heat engine 1 through the reversing device 4 . The output end of the crankshaft 2 at the front end means that the crankshaft 2 is arranged longitudinally and its output direction faces forward. In this embodiment, the clutch is a multi-plate wet clutch.

[0037] In this embodiment, the reversing device 4 outputs through the right side of the crankshaft 2, and the reversing device 2 changes the forward output direction of the crankshaft 2 into a backward output direction to finally realize the output.

[0038] The clutch 3 is connected to the crankshaft 2 through a straight or helical gear pair A5 for primary transmission, and the output end of the clutch 3 faces backward and is connected to the input end of the revers...

Embodiment 3

[0045] Embodiment 3: This embodiment is a further improvement on the basis of Embodiment 2.

[0046] In this embodiment, in order to further make the output speed of the engine meet the input speed of the transmission arranged thereafter, a speed reduction mechanism is also provided on the crankshaft 2 to the output end of the engine, wherein the speed reduction mechanism It can be set separately, and can be set together with the reversing mechanism or the clutch.

[0047] Wherein, the deceleration device can be the gear pair A5, which can reach the input speed of the transmission through the first-stage deceleration of the gear pair A5; the deceleration device can also be the gear pair B6, which can reach The input speed of the transmission; the reduction device can also be a spur gear pair A5 and a spur gear pair B6, through the two-stage reduction of the spur gear pair A5 and the spur gear pair B6 to reach the input speed of the transmission.

[0048] In this embodiment, b...

Abstract

The invention discloses a single-cylinder engine for a three-wheeled motorcycle, comprising a heat engine (1), characterized in that: the crankshaft (2) of the heat engine (1) is arranged longitudinally and the output end of the crankshaft (2) is located at front end. By adopting the single-cylinder engine of the invention, fuel consumption and emission can be reduced.

Description

Technical field: [0001] The invention relates to a three-wheel motorcycle engine. Background technique: [0002] The engine of existing three-wheeled motorcycle, its crankshaft all is horizontal setting, promptly is arranged in parallel with rear axle, and described crankshaft output is horizontal output. Then, after reversing through the bevel gear pair, the transmission line finally changes to the longitudinal direction, and finally connects with the rear axle through the differential to transmit the power to the rear axle. [0003] Disclosed in Chinese patent CN205186460U is a kind of horizontal power system for tricycles, and specifically discloses the engine, clutch and booster speed-up assembly. Arrange the crankshaft on one side of the engine in the transverse direction of the vehicle. [0004] The layout of the engine and the clutch of the horizontal power system of the above-mentioned patent is the layout of most existing three-wheeled motorcycle engines. , will ...
