摘要： Disclosed are an adaptive chassis and a robot. The chassis includes: a support (110), a first wheel (101) and a second wheel (102) arranged at two sides of a first end of the support (110), a first suspension seat (120) arranged at a bottom side of a second end of the support (110), a first rotating shaft (121) arranged on the first suspension seat (120), a first crossbeam (130) connected with the first rotating shaft (121) and being capable of rotating around the first rotating shaft (121), and a third wheel (103) and a fourth wheel (104) arranged on two ends of the first crossbeam (130). An axis of the first rotating shaft (121) is consistent with a moving direction of the chassis. When a state of a supporting surface changes and one of the third wheel (103) and the fourth wheel (104) gets out of contact with the supporting surface, the out-of-contact one of the third wheel (103) and the fourth wheel (104) can rotate around the first rotating shaft (121) by means of the first crossbeam (130) to make contact with the supporting surface.

摘要： A bogie for a forestry vehicle is disclosed that includes a bogie body, which has a first wheel hub for arrangement of a first wheel and a second wheel hub for arrangement of a second wheel. The bogie includes a swing arm pivotably hinged at a first end portion on the bogie body, and at a second end portion has a wheel hub for arrangement of a center wheel between the first wheel and the second wheel. The bogie further includes a spring and/or damper element, which at one end portion is hinged on the bogie body and at the other end portion is hinged on the second end portion of the swing arm and by means of which the swing arm is capable of being applied with force. A vehicle, in particular a forestry vehicle, is also disclosed having at least one bogie axle with such a bogie.

摘要： A preferred embodiment of the present invention includes a triple torsion axle system and kit with various features to help reduce or prevent damage that otherwise may occur with large loads. For example, each axle assembly includes larger diameter caps on the ends of each torsion bar to prevent the bar from pulling out of its outer tube during high side loads. In another example, the outer end of the torsion bar has a rounded surface that is fixed to a swing arm so as to better equalize the stress around the weld joint. Additionally, the triple torsion axle is configured such that when the vehicle is unloaded, the middle axle assembly supports more weight than the two adjacent axle assemblies. However, when the vehicle is loaded, all three axle assemblies provide similar support to the vehicle.
摘要翻译：本发明的优选实施例包括具有各种特征的三重扭转轴系统和套件，以帮助减少或防止在大负载下可能发生的损坏。例如，每个轴组件包括在每个扭杆的端部上的较大直径的盖，以防止杆在高侧载荷期间从其外管拉出。在另一示例中，扭杆的外端具有固定到摆臂的圆形表面，以便更好地均衡焊接接头周围的应力。另外，三重扭转轴构造成使得当车辆卸载时，中轴组件比两个相邻的轴组件支撑更多的重量。然而，当车辆被加载时，所有三个轴组件都为车辆提供类似的支撑。

摘要： A vehicle is provided which maintains a substantially constant weight, and therefore traction, on all wheels, despite one wheel moving considerably higher or lower than the others, while avoiding a very soft spring suspension. The vehicle includes a chassis or body to be supported and a pair of side suspensions at either side of the body. In a six wheel vehicle, each side suspension includes a middle wheel, and front and rear linkages repectively coupling the front and rear wheels to the middle wheel. A body link pivotally connects the front and rear linkages together, with the middle of the body link rising or falling by only a fraction of the rise or fall of any of the three wheels. The body link pivotally supports the middle of the length of the body. A transverse suspension for suspending the end of the body on the side suspensions includes a middle part pivotally connected to the body about a longitudinal axis and opposite ends each pivotally connected to one of the side suspensions along at least a longitudinal axis.
摘要翻译：尽管一个车轮相对于其他车轮移动得比较高或更低，但是在避免非常柔软的弹簧悬架的同时，提供一种车辆，其保持在所有车轮上的基本上恒定的重量并因此保持牵引力。车辆包括待支撑的底架或主体以及身体两侧的一对侧悬架。在六轮车中，每个侧悬架包括中间轮，前后连杆将前轮与后轮分别连接到中间轮。身体连接将前连杆和后连杆枢转地连接在一起，身体连杆的中部仅上升或下降三个轮中的任何一个的上升或下降的一小部分。身体连接枢轴支撑身体长度的中间。用于将身体的端部悬挂在侧悬架上的横向悬架包括围绕纵向轴线枢转地连接到主体的中间部分，并且相对的端部各自至少沿纵向轴线枢转地连接到侧悬架中的一个。

摘要： Vehicular wheel suspension units consist of primary support frames upon which plural tandem wheel assemblies are suspended through trailing pivotal link arms. Additional interconnecting linkage means between the several independently suspended wheel assemblies allow the assemblies to operate in unison on rough terrain in a compensating mode to maintain a level and smooth shock-free ride with maximum roll stability. The system is purely mechanical without resort to cables, hydraulics or pneumatics. The wheel suspension is adjustable to raise or lower the vehicle main frame or bed and to lock it at a desired elevation in a safe manner while the vehicle is at rest. The system is applicable to trailers and other vehicles.
