本发明涉及车轮系统领域,具体地说是一种低非簧载质量近轮IPASS系统,包括:轮轴调节系统,其设有一个独立电动机控制车轮与车身的距离实现调节轮距;转向系统,其设有一个由独立电动机驱动的小齿轮沿着安装在装置顶部的转向内齿轮滚动实现转向,且电动机和齿轮隐藏在转向空心轴中减少垂直高度;近轮推进系统,独立的推进电动机通过花键组件、锥齿轮减速器和行星齿轮减速器传递转矩控制车轮前进和后退;独立的悬架系统,其采用液压减震和支撑系统,在不平坦的路面上行驶时,弹簧吸收垂直运动产生的冲击。本发明在车辆运动期间为每个车轮提供了独立的推进/制动、轴距控制、转向和悬架系统,可用于自适应优化牵引控制,实现多种转弯运动功能。
The present disclosure provides a machine and mechanism of an electrically controlled low-unsprung-mass wheel unit for vehicles. The design incorporates independent propulsion/braking, axle control, steering, and suspension (IPASS) of each wheel during vehicle movement. The purpose of the design is for a traction-adaptively-optimization (TAO) control which include but not limited as the following: 1) better road surface gripping and ride quality by lower unsprung mass; 2) safer, quicker, and sharper turning ability—transformative turning; 3) adaptive obstacle avoidance; 4) a list of new, unique, and advanced vehicle motion features. The mechanism comprises at least: an axle adjustment that controls the distance of a wheel from the vehicle body, which allows for the outward extension of the wheel via a slider. The slider is connected to a linear actuator, which is powered by the first independent electric motor for track width adjustment. A steering system includes a pinion, powered by the second independent motor, rolls against an inner gear at the top of the unit turn in opposing directions. Hiding the motor and gears in the hollow shaft results in an extremely low profile. A propulsion system, powered by the third independent electric motor, controls the wheel's forward and backward motions using a spline, bevel gear reducer, and planetary gear reducer. Each wheel unit also has an independent suspension system located inside the wheel rim. The suspension uses a hydraulic dampening and supporting system and springs to absorb the shock from vertical movement when driving on uneven surfaces.
