A platform to replace under-the-hood engine assembly of a conventional internal combustion engine vehicle. The platform includes a backbone frame and a tower frame secured to the backbone frame towards a vehicle front. The backbone frame and the tower frame are secured to chassis frame of the vehicle through a three point isolator mounting system. A plurality of electric drive components, such as battery radiators, electric-axle and high-voltage accessories cooling system radiator, air conditioning condenser, cooling fans, brake retarder, DC-DC voltage converter(s), HVAC compressor, inverter(s), low voltage batteries package, air compressor, pumps, etc. are secured to the backbone frame and the tower frame to support the electric motor of the electric vehicle.

A method and system for swapping batteries in an electric vehicle is disclosed. The method includes dismounting a first battery assembly, moving to a second battery assembly and mounting the second battery assembly onto the vehicle. Mounting and dismounting are accomplished by an onboard mounting and dismounting system. The method can be used in a zero infrastructure environment such as an underground mine since mounting and dismounting are accomplished by components on the vehicle itself. An auxiliary battery pack powers the vehicle during between dismounting a battery pack and mounting another battery pack.

The present invention relates to a controlling apparatus for a powertrain of an electric vehicle, wherein the electric vehicle comprises a gearbox having an input shaft, a first electric machine and a second electric machine being coupled to the input shaft of the gearbox. The controlling apparatus is configured to control the operation of the first and second electric machines by the steps of: changing the speed of the first and second electric machines to reach a target speed of the input shaft; determining that the speed of the input shaft is within a target range of the target speed; setting one of the first and second electric machines in a first control mode, the first control mode being speed control to adjust for changes so that the target speed of the input shaft can be kept when reached, and setting the other one of the first and second electric machines in a second control mode being different to the first control mode, in response of determining that the speed of the input shaft is within the target range.

An electrically driven axle assembly is disclosed. In various embodiments, the electrically driven axle assembly includes a main housing; a differential plate configured for mounting within the main housing; a differential assembly, the differential assembly disposed adjacent the differential plate and having a bearing configured for mounting within a plate orifice that extends within the differential plate; a first drive shaft having a first inboard end connected to the differential assembly and a first outboard end configured to receive a first wheel; a first electric machine configured to drive the differential assembly; and a first gear assembly configured to operably couple the first electric machine to the differential assembly.

A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a truck, a tractor unit, a trailer, a tractor-trailer configuration, at a tandem, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

A vehicle frame component for limiting the movement of the wheel of the vehicle toward the cab of a cab on frame vehicle including a base member welded to openings in the frame side rail and extending outwardly and located proximal the wheel structure. In one embodiment the vehicle frame component is located forward of the wheel and includes a tire puncture device to deflate the tire during an offset front impact and in a second embodiment the vehicle frame component is located rearward of the wheel. The vehicle frame component has particular utility during an offset front impact where the offset is less than approximately twenty-five percent (25%) of the width of the vehicle.

A mining dumper having a power transmission system arranged for moving the mining dumper. The power transmission system includes at least one electric motor arranged for applying additional power for moving the mining dumper and at least one energy storing device for supplying electric energy to the electric motor. A method for intensifying a moving of the mining dumper is also provided.

An electric vehicle may include a frame, a set of wheels, and an electric propulsion system comprising an electric motor and a primary battery assembly including a first battery pack that powers the electric motor. The vehicle may also include an auxiliary battery pack configured to power the electric motor when the primary battery assembly is disconnected from the electric motor. The primary battery assembly may be non-destructively removable from the frame. In addition, the auxiliary battery pack may be fixedly attached to the frame.

A fuel tank for a truck, the fuel tank having a fuel tank body with a peripheral wall and end walls that define at least one receptacle to receive a liquid or gaseous medium. At least one baffle is fixedly attached to the inside surface of the peripheral wall via an inner fixing member. An outer fixing member is to fixedly attach the fuel tank body to the chassis of the truck, and is also connected to the inner fixing member through the peripheral wall.

A haulage vehicle includes a body, a load measurement device that measures a mounted load value of the body, a traveling electric motor, and a travel control device that outputs an electric motor command value, the travel control device sets a backward movement limiting set value to ON when it is determined that the haulage vehicle is in execution of either loading work or dumping work, and sets the backward movement limiting set value to OFF when a forward position signal and an accelerator pedal command value are inputted, an electric motor command value formed of a backward movement limiting command value is outputted to the traveling electric motor when the backward movement limiting set value is ON, and an electric motor command value formed of a normal command value is outputted to the traveling electric motor when the backward movement limiting set value is OFF.
