Right three-wheel motorcycle frame

Abstract

The invention discloses a right three-wheel motorcycle frame which comprises a main beam, a crotch camber beam and a goods box supporting frame. A front fork vertical pipe for installing a front fork steering column is welded on the main beam, a left longitudinal beam and a right longitudinal beam of the goods box supporting frame are fixed through a welded front beam and a welded rear beam, the front end of the main beam extends forwards, and a motorcycle head vertical pipe for installing a steering column is arranged in front of the front fork vertical pipe and welded at the front end of the main beam. The axis of the motorcycle head vertical pipe and the axis of the front fork vertical pipe both intersect with the axis of the main beam, and a motorcycle frame structure that the front fork vertical pipe is arranged behind the motorcycle head vertical pipe is formed. A front fork of the right three-wheel motorcycle is moved backwards, invalid distance between the front end of the front wheel of the right three-wheel motorcycle and the front end of a headlamp is shortened, the goods box supporting frame can be further lengthened within a national-regulated whole motorcycle length limiting value of the right three-wheel motorcycle, transportation efficiency is improved, and use requirements of customers are met.

Description

technical field [0001] The invention relates to the field of three-wheeled motorcycles, in particular to a frame of a three-wheeled motorcycle. Background technique [0002] As an economical and practical means of transportation, three-wheeled motorcycles are very suitable for China's national conditions. They are widely used in urban and rural areas across the country, and are favored by more and more people, especially low-income earners. Since the country stipulates that the length limit of the three-wheeled motorcycle is 3.5m, the three-wheeled motorcycle cannot be lengthened. But the driving section of traditional three-wheeled motorcycle has taken a larger space, especially the invalid length between the front wheel front point of the three-wheeled motorcycle and the front end of the headlight is very long, making the vehicle of the three-wheeled motorcycle The length of frame is restricted, and then has limited the length of container supporting frame, makes regular ...

AI Technical Summary

Problems solved by technology

But the driving section of traditional three-wheeled motorcycle has taken a larger space, especially the invalid length between the front wheel front point of the three-wheeled motorcycle and the front end of the headlight is very long, making the vehicle of the three-wheeled motorcycle The length of the frame is limited, which in turn limits the length of the cargo box support frame, so that the three-wheeled motorcycle cannot be installed with a longer cargo box

However, some consumers who use three-wheeled motorcycles to transport low-density or loosely structured goods need longer and larger cargo boxes. The traditional three-wheeled motorcycles are too small and the transportation efficiency is too low to meet consumer demand

[0003] In addition, since only one standpipe is welded on the main beam of the traditional three-wheeled motorcycle frame, only one steering column can be installed, that is, the front fork steering column, and the upper end of the front fork steering column is directly installed with the handle pipe. The vibration of the road surface has a great impact on the hand of the three-wheeled motorcycle driver; at the same time, because the welding part of the main beam of the traditional three-wheeled motorcycle frame and the cargo box support frame is located at the front and rear of the three-wheeled motorcycle that is easy to break The midpoint of the wheelbase is not conducive to driving safety; moreover, due to the short frame of the traditional three-wheeled motorcycle, the installation position of the rear axle is more forward than the support frame of the cargo box. When going uphill, the head of the three-wheeled motorcycle is easy to tilt, which is not conducive to driving safety
