A spatial frame structure of a vehicle designed for connecting structural assemblies. The described frame construction allows the use of interchangeable high-capacity fuel tanks. As a result, most structural assemblies are mounted to the outside of the frame, thus creating additional space in which elements of alternative fuel and energy source systems (e.g. natural gas tanks, electric batteries) can be assembled. This makes it possible to increase the working time of the agricultural vehicle. The frame construction comprises rigidly interconnected longitudinal tubular beams, transverse, perpendicular and diagonally arranged structural pipes, additionally connecting stiffness elements. The structure includes fastening elements for connecting the following structural assemblies: rear wheel hubs, which are assembled with electric drives; mechanical implement coupling device; structure of replaceable fuel tanks; door platform; folding driver's cab; chassis steering axle with electric drive; side component containers; power plant; mechanical coupling device for trailers and semi-trailers.

A subframe structure includes: a left-right pair of extension members arranged below a power plant, arranged in a forward part of a vehicle, the left-right pair of extension members each extending in a vehicle front-rear direction and each having a rear end portion; and a rear member connected to the rear end portions of the pair of left-right extension members, the rear member extending in a vehicle width direction. The rear member has a rearward part in which a recessed portion recessed downward is formed. The rear member has an upper face on which a steering device is to be mounted and at least a portion of a motor of the steering device is to be placed in the recessed portion.

A truck frame includes: a first side rail including a first web, a first top flange formed on a top end of the first web, and a first bottom flange formed on a bottom end of the first web; a second side rail spaced apart from the first side rail to face the first side rail, and including a second web, a second top flange formed on a top end of the second web, and a second bottom flange formed on a bottom end of the second web; a reinforcing structure connecting the first top flange of the first side rail and the second top flange of the second side rail, and connecting the first bottom flange of the first side rail and the second bottom flange of the second side rail; and a component mounting space defined by the reinforcing structure between the first web of the first side rail and the second web of the second side rail.

A Shock-Absorbing Energy Dissipation Padding (SAEDP) is coupled to the compartment of an autonomous on-road vehicle, and is located, during normal driving, at eye level in front of an occupant who sits in a front seat of the vehicle. The vehicle further includes a stiff element that supports the SAEDP and resists deformation during collision in order to reduce compartment intrusion. The stiff element is located, during normal driving, at eye level between the SAEDP and the outside environment. Optionally, a camera takes video of the outside environment in front of the occupant, and a computer generates for the occupant a representation of the outside environment.

A large mirroring element is located in front of an occupant who sits in a front seat of an autonomous on-road vehicle. The large mirroring element provides the effect of reflecting light arriving from the occupant's direction. Optionally, a camera takes video of the outside environment in front of the occupant, sends the video to a computer that generates a representation of the outside environment in front of the occupant at eye level, and a display located in front of the occupant presents the representation to the occupant.

In a vehicle body front structure, a sub frame is fixed to front mount brackets and rear mount brackets of a pair of front side frames. A power unit is arranged on the front side of the sub frame in the vehicle body, and the power unit is supported by the pair of front side frames. A tilt surface is formed on the sub frame, and the tilt surface tilts to ascend toward the rear of the vehicle body. A rear portion of the power unit faces the tilt surface.

A control arm includes a wheel side end, a body side end, a first connecting member extending between the wheel side end and the body side end, a second connecting member extending between the wheel side end and the body side end, and having a reduced section portion, and a fracture zone extending through the first and second connecting members in a substantially fore-aft direction of the vehicle, the reduced section portion being within the fracture zone. A thickness of the reduced section portion is tunable to establish a controlled fracturing during a small overlap rigid barrier impact event where: (i) an initial fracture of the first connecting member occurs within the fracture zone, and (ii) a secondary fracture of the second connecting member occurs within the fracture zone at the reduced section portion, to thereby provide a desired rearward trajectory of the wheel assembly during the impact event.
