Sand beach cross-country bicycle

Abstract

A sand off-road vehicle is mainly composed of a steering system (20), a brake system (30), a transmission system (50), a drive system (70), an electrical system (80), a frame (10), wheels (90) and so on. It also includes a two-wheel or four-wheel independent suspension (60) that includes front suspensions and rear suspensions. The frame (10) is mounted on wheels via the suspension (60). The transmission system (50) is located at the rearward of the frame (10), and its two transmission quadrate beams are fixed on inner sides of wheels (90). The drive system (70) is located at the rearward of the frame (10), and the power of its engine is transferred to the transmission system (50) through a drive pulley, a transmitted belt (508) and a driven pulley, or the engine is connected to the drive pulley via a middle transmission, and then the power is transferred to the transmission system (50) through a drive pulley, a transmitted belt (508) and a driven pulley.

Description

【Technical field】 [0001] The invention relates to a vehicle structure, in particular to a beach mountain bike which integrates sports, leisure and entertainment or engages in special field operations. 【Background technique】 [0002] All Terrain Vehicle is the translation of All Terrain Vehicle (abbreviated as ATV). In China, it is usually called "ATV". quad bike". It has a wide range of uses, covering fields such as agriculture, tourism, animal husbandry, forestry, exploration, geological exploration, fire protection, hunting, and military affairs. Because it is not restricted by road conditions, it is widely used in the United States, Canada, Spain, Australia, etc. It is widely used in the country and shows an increasing trend year by year. According to the statistics of the Motorcycle Industry Council (Motorcycle Industry Council), the current global ATV market size is about 1 million, of which 80% of the demand comes from the United States, and the market prospect is ve...

AI Technical Summary

Problems solved by technology

Since the existing ATV manufacturers, especially those who have changed production from motorcycle manufacturers, the ATVs produced are basically similar in appearance to motorcycles, and some parts are also the same as motorcycles, so there are still many problems in the performance and structure of ATVs. Defects and deficiencies, for example, some products have a high center of gravity, and the driver needs to adjust his center of gravity to maintain the balance of the vehicle during driving, which is prone to rollover accidents and lacks safety; some products have relatively single performance and can only It is suitable for driving on mountain roads, or can only be driven on muddy and sandy beaches, and all of them have poor passability; some products have insufficient power performance and poor off-road climbing ability; some products have complex structures, unattractive shapes, and similar appearances; Some products have a high failure rate, short service life, etc., which eventually lead to a decline in the market competitiveness of the product and seriously restrict the development of ATV manufacturers.
