摘要： A personal ability vehicle (PMV) includes a frame with front and rear subframes. A steering mechanism is mounted on the front subframe and includes a steering front wheel connected to a tiller. The rear subframe includes a suspension mount comprising a pair of rear support legs. An anti-tip suspension includes a pair of trailing arms each mounting a trailing wheel. Each trailing arm is pivotally mounted on a respective support leg whereby the suspension is inevitable through a limited range of motion about a transverse suspension pivotal axis. A pair of spring assemblies are attached to the trailing arms and are adapted for selectively engaging the support legs to provide a counter-rotational torque force around the suspension pivotal axis in order to resist backwards tipping of the PMV, for example, when it is ascending an inclined sloping surface. Relatively uniform proportional, weight distribution on said steering front, main and trailing wheels is maintained throughout a range of loads.
摘要翻译：个人能力车辆（PMV）包括具有前后子框架的框架。转向机构安装在前副车架上并且包括连接到分拣机的转向前轮。后副车架包括悬架，其包括一对后支撑腿。反尖端悬架包括一对拖臂，每个后臂安装后轮。每个牵引臂枢转地安装在相应的支撑腿上，由此悬挂通过围绕横向悬架枢轴的有限的运动范围是不可避免的。一对弹簧组件附接到拖臂上，并且适于选择性地接合支撑腿以提供围绕悬架枢转轴线的反向旋转扭矩力，以便抵抗PMV的向后倾斜，例如当其上升时倾斜的倾斜表面。在整个负载范围内，保持在所述转向面，主轮和后轮上的相对均匀的比例，重量分布。

摘要： A personal mobility vehicle includes a main frame unit with front and back ends, both with wheels thereon, a steerable front wheel, an operator's seat and vehicle controls. A pair of spaced rear wheels are mounted at the back end of the vehicle and include moveably mounted axles supporting the rear wheels and connected to arms with mechanisms for selectively angularly moving the axles outwardly and inwardly of the main frame unit to vary wheel base and wheel track. A motor is connected to the wheel support structure for remotely varying the wheel base and wheel track. A separate drive motor is operatively connected to the wheels for movement of the vehicle.
摘要翻译：个人移动车辆包括具有前端和后端的主框架单元，两者都具有轮子，可操纵的前轮，操作者座椅和车辆控制。一对隔开的后轮安装在车辆的后端，并且包括可移动地安装的轴，其支撑后轮并且连接到具有机构的机构，用于选择性地使轴线向主体框架单元向外和向内移动，以改变车轮基座和车轮跟踪。马达连接到车轮支撑结构，用于远程改变车轮基座和轮轨。单独的驱动马达可操作地连接到车轮以用于车辆的运动。

摘要： A personal mobility vehicle includes a floor pan with a rear drive unit at one end and a steerable front wheel at the other end. The drive unit is separable from the floor pan and includes spaced apart, differentially connected rear wheels, an electric motor, and belts and pulleys drivingly connecting the motor to a differential unit. The front wheel is steered by a tiller. A seat with a folding back is removably connected to the floor pan toward the pan rear end to concentrate the weight of the driver over the rear wheels to aid in traction. A brake is provided on the front wheel and is lockable for parking purposes. Each of the drive unit, seat unit, a battery, and a floor pan unit weighs less than thirty pounds such that the separated components can be easily lifted and manipulated for transportation of the vehicle between sites of use.
摘要翻译：个人行动车辆包括在一端具有后驱动单元的底盘和另一端的可转向前轮。驱动单元可与地板盘分离并且包括间隔开的差分连接的后轮，电动马达以及将马达驱动地连接到差速单元的皮带和皮带轮。前轮由耕耘机转向。具有折叠的座椅可拆卸地连接到底盘向着锅后端，以将驾驶员的重量集中在后轮上以帮助牵引。在前轮上设有制动器，并可为停车目的而被锁定。驱动单元，座椅单元，电池和落地盘单元中的每一个重量小于30磅，使得分离的部件可以容易地提升和操纵以在车辆在使用场所之间运输。
