Abstract:
A chassis system (47), (53) and suspension module for vehicles comprising a subsystem for each wheel, incorporating a lateral torsion bar (1) and co-axial enveloping damper unit (9), featuring active-adaptive suspension characteristics. Four pre-fabricated suspension modules are situated inside respective box-structures (20), connected via wheelbase (39) and track (38) members, allowing the storage of heavy elements (such as batteries or fuel-cells) make up the chassis. The chassis being robust and self-carrying is enhanced, using upper body members (45), in terms of structural rigidity, for a given wheelbase, achieveing high impact-energy absorbtion. The suspension arms (5) can incorporate upper and lower members (42), (43), articulation, connect internally or externaly to the suspension module, and transmit drive and brake forces to the wheels. The suspension module, the box-structure, the torsion-bar/damper unit (17), drive (48) and transmission (54) unit, suspension arm and steer module, featuring asymmetrical steer characteristics, can be reproduced on each corner of the chassis, featuring electronic control without mechanical connection (steer by wire), constituting the chassis of the vehicle (53).

Abstract:
ABSTRACT A wheel suspension system for a chassis of vehicle includes at least two wheel assemblies. Each wheel assembly includes a trailing arm which is substantially aligned with forward motion direction of the vehicle, having a first and second ends, pivotally connected at the first end to the chassis of the vehicle and coupled to a wheel axis at a location adjacent the second end, and a shock absorber coupled to the chassis or an extension thereof, the shock absorber coupled to the wheel axis, for damping motion of the wheel axis due to shocks exerted by a rough surface on which the wheels travel.
Abstract:
Lightweight wheeled surface vehicles of various types and sizes constructed chiefly from commercial off-the-shelf (COTS) parts, incorporate alternate suspensions, e.g. swingarms. One embodiment provides a vehicle incorporating a cellular body design wherein the vehicle is constructed from a varying number of substantially identical cells, assembled end-to-end to produce vehicles of varying size and capacity. Additional embodiments include lightweight passenger vehicles, such as automobiles, manufacturable from COTS parts, including independent suspensions providing large vertical wheel travel. One embodiment provides an automobile-type vehicle having a roll-cage frame, and a lightweight, exo-skeleton external frame, provided in multiple wheel configurations, e.g. three- or four-wheeled configurations. Body panels are quickly and easily attached to the tubular frame and also easily removed and switched and readily replaceable. Bicycles are equipped with electric pedal assist units. Additionally, a pneumatic pedal assist reduces peak power requirements and prolongs battery life.
Abstract:
A non-torque reactive air suspension exhibiting excellent roll stability characteristics is shown to include frame hangers mounted to frame rails extending longitudinally on opposite sides of a vehicle. Longitudinally extending beams are connected to the frame hangers at one end and extend parallel to the frame rails. At their other ends, the beams are joined by a crossbrace extending laterally across the vehicle centerline. In a central portion thereof, the beams have an axle pivot bore to which an axle clamp assembly is connected, the axle clamp assembly clamping a drive axle housing for the vehicle. The axle pivot bore is generally aligned with the drive axle. A control rod assembly is connected to suspension or frame components. Together with the beams, the control rod assembly forms a parallelogram configuration wherein the beams form the lower linkages of that configuration and the control rods included within the control rod assembly form the upper linkages of that configuration.
Abstract:
An axle/suspension system (40) for a wheeled vehicle, in which the vehicle has a frame (12), includes an integral arm structure (42) that includes an attachment member (50) for connecting the integral arm structure (42) to the vehicle frame (12). A flexible transition member (54) is connected to and extends from the attachment member (50) and a truss structure (56) is connected to and extends from the transition member (54). The flexible transition member (54) may be generally curved or angular and enables pivotal movement of the integral arm structure (42) and cooperates with the truss structure (56) to distribute forces encountered by the axle/suspension system (40). The truss structure (56) may include a truss member (72) that replaces a conventional axle tube. Optionally, two axle/suspension integral arm structures (92) may be used to capture a conventional axle tube.
Abstract:
Изобретение относится к области наземного транспорта с электрическим приводом колес, в частности, к электромобилям, электробусам, гибридным транспортным средствам и т.д., в которых приводной электродвигатель расположен в непосредстванной близости от приводимого им колеса. Техническим результатом является снижение массы и габаритов подвески и транспортного средства. Сущность полезной модели заключается в том, что независимая рычажная подвеска транспортного средства с мотор-колесом, имеющим ступицу с размещенным в ней приводным валом колеса, снабжена рычагом, который расположен продольно в направлении движения транспортного средства и выполнен одноплечим в виде полого корпуса. В корпусе продольного рычага размещены приводной электродвигатель и зубчатая передача, посредством которой вал электродвигателя связан с приводным валом колеса. Причем зубчатая передача снабжена ведущей и, по меньшей мере, одной ведомой шестернями, которые расположены несоосно. Первый конец рычага подвески соединен со ступицей колеса, а второй его конец соединен шарнирно с шасси транспортного средства с возможностью качания рычага с колесом относительно шарнира.
