On the other hand, larger vehicles have a higher center of gravity, so the vehicle may roll over during a sharp turn and cause a crash. Larger vehicles must slow down and use a larger turning radius to maintain stability when cornering

Abstract

The invention relates to the field of wheel systems, in particular to a low-unsprung-mass near-wheel IPASS system. The system comprises a wheel axle adjusting system, which is provided with an independent motor for controlling the distance between wheels and a vehicle body to adjust the wheel track; a steering system, which is provided with a small gear driven by the independent motor to roll along a steering inner gear installed on the top of the device to achieve steering, wherein the motor and the gear are hidden in a steering hollow shaft to reduce the vertical height; a near-wheel propelling system, which independently drive a motor to transmit torque to control the advancing and backing of wheels through a spline assembly, a bevel wheel speed reducer, and a planetary gear speed reducer; and an independent suspension system, which adopts a hydraulic damping and supporting system, wherein when driving in uneven ground, the impact generated by vertical movement can be absorbed by springs. During the vehicle driving process, independent propelling / braking, axle distance control, steering, and suspension system are provided for each wheel, self-adaptive optimized traction control is realized, and multiple steering functions are achieved.

Description

technical field [0001] The invention relates to the field of wheel systems, in particular to a low unsprung mass near-wheel IPASS system. Background technique [0002] In recent years, technological developments have made possible what was previously impossible. For example, the automotive industry is considering the use of in-wheel and / or near-wheel mechanisms or systems with independent propulsion to create simpler, more efficient and easier-to-control vehicles. [0003] In-wheel and near-wheel systems have separate propulsion motors and are typically incorporated into or near the hub as an electric motor system for direct drive wheel rotation. This motor is also known as an in-wheel motor, near-wheel motor, edge-of-wheel motor or in-wheel motor. (All descriptions made in the present invention will apply equally to both in-wheel and wheel-near systems. To maintain simplicity and generality, the term near-wheel system will be used interchangeably with in-wheel system, whi...
