Disclosed is a self-balancing device for self-propelled off-road RV box body. The self-balancing device includes an auxiliary beam body for connecting with a bottom end of the RV box body, a front triangular balance beam body, a rear triangular balance beam body and an axle-holding device for connecting with a RV chassis girder. The front triangular balance beam body and the rear triangular balance beam body are arranged close to both ends of the auxiliary beam body respectively. The axle-holding device is arranged between the front triangular balance beam body and the rear triangular balance beam body. Both the front triangular balance beam body and the rear triangular balance beam body include a hard limit structure for limiting a swing angle of the RV box body. The axle-holding device includes a soft limit structure for horizontally resetting the RV box body.

A vehicle front section structure includes left and right front side frame. A deformation portion configured to undergo compression deformation in the vehicle front-rear direction at a time of head-on collision of the vehicle is provided at a front end portion of each of the left and right front side frames. Left and right front side members that support a floor section of a vehicle cabin extend along the vehicle front-rear direction at a vehicle upper side with respect to the left and right front side frames. Front sections of the left and right front side members and the corresponding left and right deformation portions are connected by left and right coupling members. The left and right coupling members are configured so as to more readily undergo plastic deformation under collision load at a time of head-on collision than the left and right front side members.

A structural support system for a vehicle having a longitudinal axis extending from a front of the vehicle to a rear of the vehicle includes a cradle configured to support an engine of the vehicle, a structural side rail assembly having first and second side rails, a first set of six cradle attachments coupling the cradle to the first side rail, and a second set of six cradle attachments coupling the cradle to the second side rail. A predetermined portion of the cradle attachments of both the first and second set of six cradle attachments are designed to intentionally detach during a frontal impact event to facilitate absorbing impact energy and reducing deceleration and passenger compartment intrusion.

An autonomous transport robot for transporting a payload is provided and includes a frame with an integral payload support, a transfer arm connected to the frame for autonomous transfer of payload to and from the frame, and a drive section with at least a pair of traction drive wheels astride the drive section, the drive section being connected to the frame. The at least the pair of traction drive wheels have a fully independent suspension coupling each traction drive wheel of the at least the pair of traction drive wheels to the frame, with at least one intervening pivot link between at least one traction drive wheel and the frame configured to maintain a substantially steady state traction contact patch between the at least one traction drive wheel and a rolling surface over rolling surface transients throughout traverse of the at least one traction drive wheel over the rolling surface.

A subframe for a vehicle, which comprises a first and second longitudinal member, wherein the longitudinal members extend in a longitudinal direction (x) and are relatively offset in a transverse direction (y) of the subframe, a transverse front member connectable to the first and second longitudinal member at a front section of the subframe, a transverse rear member connectable to the first and second longitudinal member at a rear section of the subframe.

A rigid suspension tower structure includes a sus-tower for supporting a damper, and a bracket for mounting a component to be secured to the sus-tower. The sus-tower includes a curved side wall portion joined to a front side frame of a vehicle body and extending upward, and a top portion supporting the upper end of the damper. The side wall portion has a pair of mounting portions made of bulging portions. The mounting portions are formed on mutually different sides in a vehicle front-rear direction with a virtual line interposed therebetween, the line being formed by intersecting the side wall portion and a plane that extends parallel to a vehicle width direction and passes through the central axis of the damper. The bracket straddles the line and is secured to the mounting portions.
