Preferred vehicles comprise a multi-link suspension system having a plurality of links, at least some of which can move independently of one another. The skid plate is preferably disposed below the two bottom links of the suspension system. The skid plate can be fixedly attached to one of the two bottom links. The skid plate can be coupled to the other of the two bottom links such that the skid plate can move with respect to that link. | 2022-08-11 |
20220250692 | A MOTOR-VEHICLE LATTICE FRAME - A motor-vehicle lattice frame that includes a plurality of structural nodes each having a central body and at least one hollow arm protruding from the central body. The lattice frame also includes a plurality of beam elements connected to each other by means of the hollow protruding arms. The structural nodes are made by an additive manufacturing technique and at least one arm of one of the nodes has an end portion opposite to said central body having a channel shape with an open cavity both at a front end of the arm and along one side of the arm. | 2022-08-11 |
20220250693 | MOBILE CRANE VEHICLE FRAME HAVING DETACHABLY CONNECTED FRAME PARTS - A vehicle frame and a mobile crane having such a vehicle frame includes a first frame part and a second frame part which can be detachably connected to each other via a common interface. The interface includes multiple points at which it is bolted to bolting elements assigned to the respective frame parts. The interface also includes at least one profile along which it engages with engaging elements assigned to the respective frame parts which, when the bolting elements are aligned with each other, are in a mutually positive-fit engagement across their extent. | 2022-08-11 |
20220250694 | Electric linear actuator for use on a retractable wheel assembly for use on snowmobiles - An electric linear actuator and retractable wheel assembly configured for use on a snowmobile is provided. The assembly includes bracket or base member configured to be attached to a ski of a snowmobile. The base member supports a linear actuator which is activated to rotate a transfer plate. The transfer plate simultaneously slides and pivots around a transfer shaft which guides and limits the movement of the transfer plate. A wheel is attached to the transfer shaft such that the wheel is configured to retract and protract relative to the ski of the snowmobile allowing the wheel to be used instead of the ski when the snowmobile is traveling on rough surfaces. | 2022-08-11 |
