Disclosed is an automobile chassis, which includes a chassis main beam, a chassis cross beam and a support cross beam. The quantity of the chassis main beams is two. The two chassis main beams are arranged in parallel. A section shape of the chassis main beam is “”, and the openings of the two chassis main beams are arranged opposite. The quantity of the support cross beams is more than one. All the support cross beams are arranged between the two chassis main beams. A length direction of the support cross beam is perpendicular to a length direction of the chassis main beam. The chassis cross beam is arranged at an end of the chassis main beam, and both ends of the chassis cross beam are respectively connected and fixed with the two chassis main beams.

Suspension systems and grounds maintenance vehicles incorporating the same are disclosed. The suspension system may include biasing elements or springs that may be adjusted to vary the preload and thus change the spring and dampening characteristics of the suspension system. In some embodiments, the system may include an adjustment mechanism that permits simultaneous adjustment of two springs via a single action. In other embodiments, features adapted to assist an operator with mounting/dismounting the vehicle are disclosed.

The present disclosure is directed to a truck including a cargo box coupled to a first rail and a second rail with a first cross member and a second cross member. The first and second rail are coupled to, and extend transverse to, the first and second cross members. A bed floor of the cargo box is physically separated from the rails by the cross members.

A frame structure for maintaining energy storage devices of a vehicle in position which is deformed in a controlled way in the event of a side-impact, in such a way to avoid deforming into the location of the vehicle seats. The proposed frame structure is adapted to deform controllably in a centre position align with a location between the vehicle seats. In this way are occupants of the vehicle kept safe since no or less deformation occur in the vehicle seat location. The above advantages are provided by that lateral support members of the frame includes a deformation zone adapted to deform in response to a lateral force exerted on the lateral support member. The deformation zone is located such that, when the frame structure is installed in the vehicle, the deformation zone is aligned with a location between seats of the vehicle.

A subframe assembly for a vehicle utilizing straight, parallel extruded longitudinal siderail members. This subframe assembly provides front-end (or rear-end) crash energy absorbance by plastically deforming, crumpling, and bending down to avoid the stackup and occupant cabin intrusion of components, such as the attached engine/motor, engine/motor mounts, steering components, and suspension components. The laterally disposed longitudinal siderail members each provide a straight, substantially uninterrupted lower load path to transfer crash energy from the lower load path crash management system beam and crashboxes or the like to a rear upper load path body in white bracket, and ultimately to the battery frame in the event of a crash, with the siderail members and crashboxes optionally being longitudinally coaxially aligned.
