The product (P.sub.F) of the wall thickness (t.sub.F) of the front part by the yield strength (Ys.sub.F) of the material of the front part is greater than the product (P.sub.R) of the wall thickness (t.sub.R) of the rear part by the yield strength (Ys.sub.R) of the material of the rear part.

A synchronous steering vehicle body includes wheels, a cab and a steering mechanism for driving the wheels and the cab to synchronously steer, steering center axes of the wheels are vertical to rotation center axes of the wheels, and the wheels are vertical to the center of the horizontal ground to be concentric to the steering center axes of the wheels, and the steering motions of the wheels and the cab are kept synchronous. The disclosure provides a synchronous steering vehicle body capable of directly achieving the synchronous steering of the wheels and the cab.

Lift axle systems for use with trucks and other heavy duty vehicles are described herein. In some embodiments, lift axle systems configured in accordance with the present technology include upper and lower control arms on each side of the vehicle that operably couple an axle to a support system attached to the vehicle chassis. The upper control arm has a first end portion pivotally attached to a support system bracket at an upper bracket location, and a second end portion pivotally attached to the axle at an upper axle location. The lower control arm has a first end portion pivotally attached to the support system bracket at a lower bracket location, and a second end portion pivotally attached to the axle at a lower axle location. In some embodiments, the upper and lower bracket locations lie in a vertical plane that extends parallel to the vertical and longitudinal axes of the vehicle, and the upper axle location is spaced apart from the lower axle location in a lateral direction that extends parallel to the lateral axis of the vehicle.

A floor mat arranged in a working machine includes a floor portion, a wall portion arranged on a circumferential portion of the floor portion, and an opening portion arranged on a part of a connecting portion of the wall portion, the connecting portion connecting to the floor portion. The floor mat includes a mat main body arranged on the floor portion, a covering portion configured to cover the opening portion, and an connecting portion configured to connect the covering portion flexibly to a circumferential portion of the mat main body.

A dual mode vehicle that operates on guided rails and roadways includes a capsule, a carriage, a front left drive system, a front right drive system, a rear left drive system, a rear right drive system, a pod control unit, and at least one battery. The carriage includes a spherical frame-housing and a base. A spherical cabin of the capsule is attitudinally mounted within the spherical frame-housing. The front left drive system, the front right drive system, the rear left drive system, and the rear right drive system each includes a motor, a drive axle, a road wheel, and a rail wheel. The road wheel and the rail wheel are axially mounted to the drive axle. The motor that is mounted to the base is operatively coupled with the drive axle through the at least one battery and the pod control unit to operate a roadway or railway transportation mode.

A longitudinal member is provided. The longitudinal member includes a front end provided with a hinge element for attaching the longitudinal member in an articulated manner to a heavy goods vehicle body, and a rear end including an attachment element for attaching the longitudinal member in a non-permanent manner to the heavy goods vehicle body. The longitudinal member includes a front part extending from the front end to an intermediate area of the longitudinal member and a rear part extending from the intermediate area to the rear end of the longitudinal member. The product (P.sub.F) of the wall thickness (t.sub.F) of the front part by the yield strength (Ys.sub.F) of the material of the front part is greater than the product (P.sub.R) of the wall thickness (t.sub.R) of the rear part by the yield strength (Ys.sub.R) of the material of the rear part.

A working vehicle is provided with a traveling vehicle, a working section which is supported on a rotatable base, an operator's cab, and a connection section. The connection section includes: a connection section body which connects the rotatable base and the operator's cab and which is provided so as to be capable of pivoting about a base-side connection section connected to the rotatable base and about the operator's cab-side connection section connected to the operator's cab; and a pivot control section which extends so as to always intersect the connection section body in the range of pivoting of the connection section body, connects the rotatable base and the operator's cab, and is provided so as to be capable of pivoting about a base-side connection section connected to the rotatable base and about an operator's cab-side connection section connected to the operator's cab.

A vehicle includes a support assembly extending between a chassis and a cab. The support assembly includes a first bracket coupled to the chassis, a second bracket coupled to the cab, a stay arm having a first end coupled to the first bracket and an opposing second end, and a locking assembly. The stay arm defines a locking interface between the first end and the opposing second end. The locking assembly includes a slide, an actuator, a release arm, and a pawl. The slide is translatable along the stay arm. The slide defines a first interface coupled to the second bracket, a second interface coupled to the actuator, and a third interface. The release arm is coupled to the actuator and the third interface. The pawl is coupled to release arm at the third interface. The pawl selectively engages with the locking interface based on a configuration of the actuator.
