Rocking three-wheels vehicle

Abstract

The utility model relates to a tricycle, which effectively arranges and supports various functional parts of the rear body, makes the rear body further compact and miniaturized, and is environmentally friendly at the same time. The rear car body (18) is connected with the rear portion of the front car body, and the rear car body is connected so that it can swing freely relative to the front car body, and the rear car body (18) is covered by an integral casing (53) , the engine (76), the rear wheels (16, 16) driven by the engine (76), and the exhaust system (52) of the engine (76) are arranged in the casing (53). The cylinder part (93) of the engine (76) is arranged in the casing (53) inclined forward. In the exhaust system (52), a catalyst pipe (107) and a muffler (111) for purifying exhaust gas are arranged, and a fuel injection valve (91) and a throttle body (107) for supplying fuel to the engine (76) are arranged. Arranged in the casing (53).

Description

technical field [0001] The present invention relates to an improvement scheme for a swingable three-wheeled vehicle, and more particularly, the present invention relates to a rear body structure, an exhaust system, an intake system structure, and an air filter intake system in a swingable three-wheeled vehicle. improvement of the road structure. Background technique [0002] As for a common type of swingable three-wheeled vehicle, a tricycle in which a cover is provided on a rear body is known (for example, see Patent Document 1). [0003] For a common type of exhaust system, a known type is that the catalyst cartridge is arranged in a casing separate from the muffler and located on the lower side of the engine (see, for example, Patent Document 2). A motorcycle exhaust system on which a muffler and a catalyst are provided is known (for example, see Patent Document 3). [0004] For the common type air intake system structure on common types of swingable three-wheeled vehic...

Problems solved by technology

Since the air filter 15 is biased to the left or right, its volume is limited and it is difficult to ensure performance.

[0026] The water droplets and dust that enter the lower air inlet 31 through the upper air inlet 30 will drop to the bottom of the lower air inlet 31, but the small water droplets and tiny dust may pass through the connecting pipes 17, 18 on the way down. , 19 into the air filter 15

[0027] In addition, as in patent document 4 Figure 5 As shown, the width of the upper intake duct 30 in the lateral direction of the vehicle body is greater than the width of the air filter 15 in the lateral direction of the vehicle body, and the width of the lower intake duct 13 also occupies almost half of the width of the air filter. There is a lot of space, so the size of the car body needs to be increased
