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...
