The multipurpose vehicle comprises a vehicle frame comprising a vehicle rack and a plurality of connector portions, a plurality of swing arms, a plurality of lever arms, a plurality of hinge arms, a plurality of wing board(s) and a plurality of side boards. Each lever arm comprises a connector arrangement for removably connecting the lever arm to the vehicle rack. A handle is connected to a connector portion of the vehicle frame and the handle is manually operable to enable adjustment of the rotation of at least two swing arm(s). The multipurpose vehicle could be positioned in multiple operating modes by operating at least one of the handle and/or connector arrangement(s). |

Dual front, single rear-wheeled three-wheeler
A three-wheeler including two front wheels and a rear wheel, left and right seats, a steering mechanism steering the front wheels, an electric motor generating a torque by electrical energy, a power transmission mechanism transmitting the torque to the front wheels, and a body frame. A center of gravity of the three-wheeler is more frontward than a front end of the two seats and than a middle point of the wheelbase, and is more rearward than a front end of the electric energy storage device. The seats is, in a top view, partially in a triangle area that has a center of each of the front wheels and the rear wheel as vertices. The electric energy storage device, in the top view, overlaps a foot-resting area and is partially in the triangle area. The electric energy storage device is between the two front wheels. |

Efficient autonomous trucks
The technology relates to enhancing the operation of autonomous vehicles. Extendible sensors are deployed based on detected or predicted conditions around a vehicle while operating in a self-driving mode. When not needed, the sensors are fully retracted into the vehicle to reduce drag and increase fuel economy. When the onboard system determines that there is a need for a deployable sensor, such as to enhance the field of view of the perception system, the sensor is extended in a predetermined manner. The deployment may depend on one or more operating conditions and/or particular driving scenarios. These and other sensors of the vehicle may be protected with a rugged housing, for instance to protect against damage from the elements. And in other situations, deployable foils may extend from the vehicle's chassis to increase drag and enhance braking. This may be helpful for large trucks in steep descent situations. |

Aerodynamic mud flap
An aerodynamic mud flap includes a body having a first lateral side, an opposite second lateral side, an upper end, an opposite lower end, a front face, and an opposite rear face. The body extends in a horizontal, vertical, and transverse directions. The body has a generally planar upper portion extending vertically from the upper end to a horizontal transition line, and an arcuate lower portion extending vertically from the transition line to the lower end. The lower portion is curved along the vertical direction such that the lower end of the body is offset from the upper end in the transverse direction and is disposed rearward of the upper end. A plurality of octagonal openings in the body extend from the front face to the rear face to allow for air flow through the mud flap from the front side to the rear side. |

Deformable bracket for translating vehicle fuel box
A system for reducing risk of fuel leakage of a vehicle during a collision includes a vehicle main body configured to support and at least partially enclose a passenger. The system further includes a fuel inlet box configured to house a fuel inlet. The system further includes a rear bracket coupled to the vehicle main body at a location aft of the fuel inlet box. The system further includes a center shaft coupled to the rear bracket and extending forward from the rear bracket. The system further includes a forward bracket coupled to the vehicle main body at a location forward relative to the rear bracket and coupled to the center shaft, the forward bracket configured to deform in response to a rear collision of the vehicle to actuate the fuel inlet box in order to reduce the likelihood of a fuel leak from the fuel inlet. |

Frame member
In a frame member, the hardness of a sheet-thickness-direction central section in a portion where a softening layer is provided is greater than or equal to 400 Hv, the softening layer has hardness smaller by at least 10 Hv than the hardness of the sheet-thickness-direction central section in the portion where the softening layer is provided, the thickness of the softening layer is greater than or equal to 2% of the sheet thickness but smaller than 20% of the sheet thickness, the hardness of the softening layer at the surface is greater than or equal to 0.5 times the hardness of the sheet-thickness-direction central section but smaller than 0.9 times the hardness of the sheet-thickness-direction central section, the softening layer has a first hardness changing area and a second hardness changing area, an absolute value ΔHv1 of a change in hardness of the first hardness changing area in the sheet thickness direction is greater than an absolute value ΔHv2 of a change in hardness of the second hardness changing area in the sheet thickness direction, and R/t≤2.5 is satisfied, where R represents the bending radius of the corner section, and t represents the sheet thickness of the corner section. |

Vehicle with tilt frame and spring damper system
A vehicle with a base frame to which at least two sprung suspensions, in particular sprung wheel suspensions, for driven, non-driven, steerable or non-steerable contact elements, for example wheels, are attached which can be steered by means of a steering knuckle and are located on both sides of the longitudinal direction of travel, in each case transversely to the direction of travel, a tilt frame, tiltable in a tilt axis with respect to the base frame. A steering tube is rotatably attached to the tilt frame in the steering axis and automatically tilts with the tilt frame, at least one track rod connected to the track rod actuating element, and a linear or rotary track rod actuating element rotatable over a guide element. The track rod actuating element is displaced by tilting the tilt frame about the tilt axis and independently thereof by rotating the steering tube about the steering axis in such a way that the steerable contact element is given a steering movement by the track rod actuating element by means of the at least one track rod and no substantial change in the camber of the contact elements takes place during cornering, wherein the vehicle comprises at least one spring damper system which is suitable and provided for reducing a pendulum tilt of a tilt frame about the vertical zero position. |
