Abstract
Methods and systems are provided for an electric heavy-duty vehicle. In one example, a system for the vehicle may include a wheel hub assembly coupled to a frame of the vehicle via a first wishbone arm and a second wishbone arm, and an air spring coupled at opposite ends to a first link and a second link, each of the first link and the second link being pivotably coupled to the frame of the vehicle, the second link further being pivotably coupled to the first wishbone arm. The air spring may be positioned above the wheel hub assembly with respect to the vehicle.
Claims20
A system for a vehicle, the system comprising:
- a wheel hub assembly coupled to a frame of the vehicle via a first wishbone arm and a second wishbone arm;
- and
- an air spring coupled at opposite ends to a first link and a second link, each of the first link and the second link being pivotably coupled to the frame of the vehicle, the second link further being pivotably coupled to the first wishbone arm,
- wherein the air spring is positioned above the wheel hub assembly with respect to the vehicle.
A system for a vehicle, the system comprising:
- a pair of front wheel hub assemblies configured with a front air suspension system, the front air suspension system comprising a first pair of air springs respectively positioned over the pair of front wheel hub assemblies;
- and
- a pair of rear wheel hub assemblies configured with a rear air suspension system, the rear air suspension system comprising a second pair of air springs respectively positioned over the pair of rear wheel hub assemblies,
- wherein each of the first and second pairs of air springs is configured for substantially axial compression without any guiding structure extending a length thereof, the substantially axial compression of the first and second pairs of air springs lowering a cabin floor of the vehicle.
A method for an electric heavy-duty vehicle, the method comprising:
- compressing air springs in a suspension system of the electric heavy-duty vehicle responsive to a request to lower a cabin floor of the electric heavy-duty vehicle, the air springs being positioned above respective wheel hub assemblies of the electric heavy-duty vehicle;
- and
- expanding the air springs responsive to a request to raise the cabin floor,
- wherein an angle between a central axis of each respective air spring and a plane of a frame of the electric heavy-duty vehicle does not change substantially during compression and expansion of the respective air spring.
