- Figures 1-18 show a modular rolling chassis for a vehicle, according to one embodiment of the present invention, generally illustrated at 100.
- the chassis is formed on a platform frame 110, and further includes a rear subframe 140, a front subframe 160 and a controls module 180.
- composite panels formed for example as fiberglass skin over an aluminum honeycomb core, are a suitable material in the manufacture of portions of the chassis 100, as will be described further below.
- Panel core might also be formed from NomexTM (a meta-aramid polymer), foam, titanium, plastic or wood, for example.
- Panel skins might also be formed from carbon fibre, KevlarTM, (a para-aramid synthetic fibre), aluminum, titanium, steel, stainless steel, or wood, for example.
- Such composite panels provide strength in tension and compression, while permitting bending and folding; they can be formed by casting, cutting and more generally machining, to achieve desired sizes, shapes, configurations and characteristics. In this regard, such panels can be readily available in standard sizes and other properties, or custom manufactured to specification. [0024] The careful deployment of such composite panels can yield a chassis
- An analogy can be drawn to a pizza box formed from a sheet of corrugated fiberboard that is cut to shape and then folded into a three-dimensional box.
- the platform frame 110 may be formed from readily available or manufactured composite panels 112, cut or otherwise formed to the desired size and shape, connected together by fasteners 114 (detailed in Figures 12- 18), for example, as illustrated, fasteners commonly used in aerospace manufacturing, or adhesives or welds for example.
- the platform frame 110 is formed as a platform 116 supporting a plurality of longitudinal joists 118 fastened thereto, and to both of which are fastened a front bulkhead 120 and a rear bulkhead 122.
- the platform frame 110 further includes a pair of lateral battery compartments 124 extending from the front bulkhead to the rear bulkhead, and adapted to removably receive a battery module 200 for electrical connection to at least one of the rear subframe 140 and the front subframe 160.
- the platform frame 110 further includes a cockpit portion 126 between the pair of lateral battery compartments 124, the cockpit portion 126 may form a structural support member of the platform frame 110, providing additional torsional and bending stiffness to the chassis 100.
- the front bulkhead 120, the rear bulkhead 122 and the pair of lateral battery compartments 124 extending therebetween may individually or in combination form a structural support member of the platform frame, providing additional torsional and bending stiffness to the chassis 100.
- the pair of lateral battery compartments 124 has at least one cooling intake (not shown) and at least one cooling exhaust 130, the cooling intake being connected to receive air from the cockpit portion 126, for example climate controlled air.
- the cooling intake may be located proximate the front bulkhead 120 and the cooling exhaust 130 located proximate the rear bulkhead 122, such that air received at the cooling intake may flow rearward through the pair of lateral battery compartments 124 and be exhausted proximate the rear bulkhead 122, in this regard, the cooling exhaust 130 may include an exhaust fan 132.
- the pair of lateral battery compartments 124 may be thermally sealed from the cockpit portion 126, such that the battery module 200 does not itself need to be sealed from the ambient environment.
- the battery module 200 includes a pair of elongated trays 202 adapted to be removably received within the pair of lateral battery compartments 124 of the platform frame 110 and a number of batteries 204, connected together in an electrical circuit as a source of power, supported on the pair of elongated trays.
- the trays 202 and the batteries 204 may on their own or in combination form a structural support member, providing additional torsional and bending stiffness to the chassis 100.
- the heavy batteries 204 (and the relatively light composite panels 112) also lower the centre of gravity of the chassis 100.
- the battery module 200 could have electrical contacts 206 for ready electrical connection to at least one of the rear subframe 140 and the front subframe 160, for example contacts 206 on the pair of elongated trays 202.
- the battery module 200 may further include mounting hardware 208, for example straps, for retaining the batteries 204 in the pair of elongated trays 202.
- the front bulkhead 120 may support a windscreen frame 134 and the rear bulkhead 122 may support a roof panel 136 that is foldable to connect to the windscreen frame 134 to enclose the cockpit portion 126.
- the rear subframe 140 is mountable to the rear bulkhead 122 and can support components such as a motor controller 142 electrically connectable to receive power from a battery module 200, a motor 144, electrically connected to the motor controller 142, a swing arm 146 which may be a swing arm as disclosed in co- pending International application PCT/CA2017/050321 filed lOMarch 2017, which is incorporated herein by reference, a drive wheel 148 depending from the swing arm 146, and a drivetrain 150 coupling the motor 144 to the drive wheel 148.
- the motor controller 142 may be electrically connectable to the controls module 180 such that a user may use the controls module 180 to direct the motor controller 142.
- the motor controller 142 is mounted to the sub-frame 140 just above the motor 144. It regulates the torque/power going the motor 144 to control speed and acceleration of the vehicle.
- the rear subframe 140 can form a structural support member, providing additional torsional and bending stiffness to the chassis 100.
- a metal sub-frame 141 used to mount the seat belt D-ring is supported on rear subframe 140.
- the rear subframe 140 may further support a cooling duct 152 between the motor 144 and the motor controller 142, to conduct air propelled by the motor 144 to the motor controller 142 for cooling. Cooling duct 152 is a small duct connecting the motor controller 142 to the motor.
- the motor 144 draws air over the motor controller 142 via cooling duct 152.
- the rear subframe 140 may be formed from readily available or manufactured composite panels 112, cut or otherwise formed to the desired size and shape, connected together by fasteners 114 or welds for example.
- the front subframe 160 is mountable to the front bulkhead 120 and can support components such as an independent suspension 162, a pair of freewheeling hubs 164 at opposite ends of the independent suspension 162, each of the hubs 164 being adapted to retain a leading wheel 166, and a steering linkage 170 operatively connected to the hubs 164, and a braking system 168 operatively connected to the hubs 164.
- the steering linkage 170 may include a single, central universal joint 172.
- the front subframe 160 can form a structural support member, providing additional torsional and bending stiffness to the chassis 100.
- the front subframe 160 may be formed from readily available or manufactured composite panels 112, cut or otherwise formed to the desired size and shape, connected together by fasteners 114 or welds for example.
- the controls module 180 includes a steering column 182 and a column support bracket 184 to which the steering column 182 can be mounted.
- the column support bracket 184 is mountable to the front bulkhead 120 to form a structural support member, in place of a cross-car beam, for example.
- the steering column 182 is operatively coupleable to the steering linkage 170 through the universal joint 172.
- the controls module 180 may include other controls, for example a brake controller 186 operatively coupleable to the braking system 168. (b) Operation of Specific Embodiments
- the platform frame 110 may be manufactured from composite panels
- the composite panel 112 and fasteners 114 instead of more demanding custom-formed composite pieces.
- the composite panel 112 need merely be cut to size and shape and drilled as needed and then easily assembled together into a platform frame 110 by simple fastening operations.
- the battery module 200 may be manufactured elsewhere and delivered for subsequent assembly into the rolling chassis 100. Similarly, for maintenance, an expired battery module 200 may be easily removed rearwardly from the battery compartment 124 and a replacement battery module 200 inserted in its place. In this regard, batteries 204 would be wired together as appropriate and supported onto the pair of elongated trays 202. The batteries 204 could be further retained in the pair of elongated trays 202 with mounting hardware 208.
- the battery module 200 may be placed in electrical connection with at least one of the rear subframe 140 and the front subframe 160 via contacts 206.
- the rear subframe 140 and the front subframe 160, and their supported components, could similarly be manufactured elsewhere and delivered for subsequent assembly into the rolling chassis 100. As with the battery module 200, such modular assembly may also be advantageous for maintenance or repair.
- the rear subframe 140 and the front subframe 160 can be simply fastened to the rear bulkhead 122 and front bulkhead 120 respectively, composite panel 112 to composite panel 112, with fasteners 114.
- Fasteners 114 are standard panel fasteners such as the threaded inserts manufactured by Witten Company, Inc. which are potted into place.
- the controls module 180 could similarly be manufactured elsewhere and delivered for subsequent assembly into the rolling chassis 100. As with the battery module 200, the rear subframe 140 and the front subframe 160, such modular assembly may also be advantageous for maintenance or repair.
- the column support bracket 184 can be mounted to the front bulkhead 120 to form a structural support member and the steering column 182 can be operatively coupled to the steering linkage 170 through the universal joint 172.
- other controls such as the brake controller 186 can be operatively coupled, for example to the braking system 168.
