All-wheel drive active side-tipping regular three-wheeled vehicle

Abstract

The invention belongs to the technical field of vehicle chassis, and relates to an all-wheel drive active side-tipping regular three-wheeled vehicle, in particular to a vehicle steering side-tipping and control technology, which consists of a front wheel steering profiling mechanism and a rear wheel side-tipping control mechanism, the front wheel rotates around the axis of the front wheel relative to the steering knuckle to adapt to the running speed of the vehicle, the front wheel and the steering knuckle revolve around the steering axis together to achieve steering of the front wheel, the front wheel and the steering knuckle jointly move in the vertical plane of the vehicle body, the front wheel is profiled to the ground, and the ground profiling motion of the front wheel is independent of the steering motion. The front wheel steering profiling mechanism achieves front wheel steering, ground profiling and front wheel self-adaptive side tipping, the rear wheel side tipping control mechanism controls side tipping of the vehicle body, the front wheels and the double rear wheels jointly drive the vehicle to run, and the all-wheel-drive active side tipping right three-wheeled vehicle is formed. Front wheels are used for profiling the ground in real time, the ground adhesive force of the front wheels is increased, all-wheel driving is adopted, and the power performance of the vehicle is improved.

Description

technical field [0001] The invention relates to an all-wheel-drive active roll positive three-wheel vehicle, belonging to the technical field of vehicle chassis, in particular to the technical field of vehicle steering roll and control. Background technique [0002] The active roll control system improves the stability, smoothness, traffic speed and safety of the vehicle by controlling the inclination of the vehicle to the inside of the curve when turning. When the road is over inclined, it automatically tilts at a certain angle to generate a balance moment to resist the centrifugal force or rollover force of the vehicle, so as to maintain a stable driving posture of the vehicle. [0003] Vehicle active roll technology is usually implemented in two ways: independent body roll, body and wheel linkage roll, the former body independent roll mode, the body is directly driven by the actuator to rotate relative to the frame, and the wheels do not roll during the body roll process....

AI Technical Summary

Problems solved by technology

[0003] Vehicle active roll technology is usually implemented in two ways: independent body roll and vehicle body and wheel linkage roll. The former independent body roll method uses an actuator to directly drive the body to rotate relative to the frame. During the body roll process, the wheels do not sideways. It is suitable for general-purpose car tires, but the control of body roll motion is complicated, resulting in poor handling stability, ride comfort, safety and reliability during vehicle driving; the latter is the linkage roll mode of body and wheels, driven by actuator The roll mechanism realizes the vehicle roll through the movement of the suspension. The body roll, vehicle steering and wheel suspension movement affect each other. The wheel tires need to use arc-shaped curved tires, but the driving stability, ride comfort and safety of the vehicle are better. , suitable for high-end vehicles; the active-roll tricycle adopts the linkage roll mode of the body and wheels, and the vehicle roll is controlled by the double rear wheels, and the single front wheel is in the middle, and the adaptive roll is adopted. Inside, the power consumption of its roll drive and control is small, but the ground adhesion of the tricycle is small and the vehicle dynamic performance is poor, which limits the application of active three-wheeled vehicles. It is of theoretical significance and practical value to further explore the all-wheel drive of tricycles, improve vehicle dynamic performance and vehicle carrying capacity
