Problems solved by technology

However, in many off-road vehicles, such as all-terrain vehicles, the amount of storage space on the vehicle is limited
Since air compressors can be bulky, storing one in a vehicle takes up a considerable amount of limited storage space

Embodiment Construction

[0030] The invention will be described with reference to an all-terrain vehicle (ATV) 10 having four wheels 18. However, it is conceivable that aspects of ATV 10 may be used in other types of vehicles such as side-by-side recreational utility vehicles (RUV), and / or in vehicles having fewer or more than four wheels 18.

[0031] figure 1 The ATV 10 is shown. ATV 10 has a frame 12 ( figure 1 Part of it is shown in), a body 14 and an internal combustion engine 16 for powering the ATV 10 are installed on the frame. Four wheels 18 are also connected to the frame 12. The wheel 18 has a low-pressure wide tire 20. The low-pressure wide tire 20 is mounted to a rim 22, which has a diameter from 25 cm to 36 cm. It is conceivable that the ATV 10 may only have three wheels 18. Low pressure wide tire 20 is inflated to no more than 2kg / cm 2 (That is not more than 196kPa or 28psi) pressure, and suitable for off-road conditions and trekking on uneven terrain. The ATV 10 also includes a straddle...

Abstract

A vehicle has a frame, at least one front wheel connected to the frame, at least one front suspension assembly connecting the at least one front wheel to the frame, at least one rear wheel connected to the frame, and at least one rear suspension assembly connecting the at least one rear wheel to the frame. At least one of the at least one front and at least one rear suspension assemblies includes an air spring. A seat is connected to the frame. An engine is connected to the frame and is operatively connected to at least one of the wheels. An air compressor is connected to the frame and fluidly communicates with the at least one air spring for supplying air to the at least one air spring. A control unit is electrically connected to the air compressor for controlling an operation of the air compressor.

Description

[0001] cross reference [0002] This application claims the priority of U.S. Patent Application No. 61 / 182,459 filed on May 29, 2009, and the entire content of the above application is incorporated herein by reference. Technical field [0003] The invention relates to a vehicle suspension system and a pneumatic system. Background technique [0004] In many all-terrain vehicles and other types of vehicles, the vehicle suspension system usually includes stabilizer bars, also known as anti-roll bars. The stabilizer bar is used to connect the laterally opposed wheels. Stabilizer bars help reduce the tendency of the vehicle to roll over when the vehicle is turning, for example. However, stabilizer bars add weight and mechanical complexity to the vehicle. [0005] Some vehicles also use air springs in their suspension systems. In such vehicles, a compressor or a pressurized gas reservoir is used to supply pressurized air or gas to the air spring. However, in a system using a compressor...
