Electric car with pre-assembled modular structure
First Claim
1. An electrically powered motor vehicle, comprising:
- a main frame;
a front axle assembly; and
a rear axle assembly,wherein said axle assemblies each comprise an auxiliary supporting frame and two suspension units that connect two respective wheel supports to said auxiliary supporting frame, andwherein at least one of said axle assemblies is a motor-driven axle with steering wheels, further comprising, mounted on the respective auxiliary supporting frame, an electric motor for driving the wheels in rotation, a control unit of said motor, a transmission unit for transmission of motion from the electric motor to the wheels, and a steering device for steering the wheel supports,wherein said main frame includes;
a front frame subassembly,a floor-panel subassembly,a rear frame subassembly, anda top frame subassembly ,wherein the auxiliary supporting frames of said front and rear axle assemblies have attachment points bolted to corresponding attachment points of said front and rear frame subassemblies,wherein each of said frame subassemblies comprises a lattice structure including steel box-section elements, preferably high-strength steel elements, andwherein the front and rear frame subassemblies have longitudinal struts designed to absorb impact energy, which have respectively front and rear ends connected together by cross members,said frame subassemblies being prearranged for being preassembled separately and subsequently assembled together to form the aforesaid main frame,wherein moreover the aforesaid floor-panel subassembly defines one or more compartments for housing batteries for supplying the aforesaid electric motor andwherein the aforesaid top frame subassembly incorporates the lateral uprights of the windscreen of the motor vehicle and at least one of the two intermediate uprights of the motor vehicle,said rear frame subassembly including a plurality of cross members defining a resting surface for the rear seat of the motor vehicle.

Abstract
An electrically powered motor vehicle includes a main frame, a front axle assembly, and a rear axle assembly. The main frame includes a front frame subassembly, a floor-panel subassembly, a rear frame subassembly, and a top frame subassembly. Each of these frame subassemblies includes a lattice structure including steel box-section elements, preferably high-strength steel elements. Each of the frame subassemblies is prearranged for being pre-assembled separately and then subsequently assembled together with the other subassemblies to constitute the main frame. The structure is such as to afford high flexibility of production, and presents at the same time considerable safety characteristics, thanks to a high capacity of absorption of impact energy. In one embodiment designed for transport of goods, the motor vehicle is equipped with a transporting body having a hollow-walled body made of plastic material, filled with foamed plastic material, preferably obtained with the rotational-moulding technique.
