COMPACT E-AXLE ASSEMBLY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240017602 titled 'COMPACT E-AXLE ASSEMBLY
Simplified Explanation
The abstract describes an e-axle assembly that includes a housing with an internal compartment. Within the compartment, there is at least one electric motor with a stator and a rotor. The rotor has a hollow space internally, where a gearing mechanism, shifting actuator, and/or a differential can be placed. In a preferred arrangement, all of these components are packaged within the hollow of the rotor, reducing the overall space and weight of the e-axle assembly.
- The e-axle assembly includes a housing with an internal compartment.
- At least one electric motor is placed within the internal compartment.
- The electric motor has a stator and a rotor that can rotate relative to the stator.
- The rotor has a hollow space internally.
- A gearing mechanism, shifting actuator, and/or a differential can be placed within the hollow of the rotor.
- In a preferred arrangement, all of these components are packaged within the hollow of the rotor.
- This internal packaging reduces the overall space and weight of the e-axle assembly.
- The smaller space and weight allotments make it easier to achieve in electric and/or hybrid vehicles.
Potential applications of this technology:
- Electric vehicles
- Hybrid vehicles
Problems solved by this technology:
- Reduces the overall space and weight of the e-axle assembly
- Allows for easier integration into electric and hybrid vehicles
Benefits of this technology:
- Improved efficiency and performance of electric and hybrid vehicles
- More compact and lightweight design
- Increased space for other components in the vehicle
Original Abstract Submitted
an e-axle assembly includes a housing extending from a first housing end to a second housing end to define an internal compartment. at least one electric motor is disposed in the internal compartment and includes a stator and a rotor rotatable relative to the stator about an axis. the rotor defines a hollow extending internally within the rotor, and at least one of a gearing mechanism, a shifting actuator, and/or a differential is disposed within the hollow (and thus packaged within the rotor). in a preferred arrangement, all and any of the gearing mechanisms, shifting actuators, and differential are disposed within the hollow of the rotor. this internal packaging of the drive components within the rotor reduces an overall space and weight of the e-axle assembly relative to the prior art designs to more easily and readily achieve the smaller space and weight allotments afforded by electric and/or hybrid vehicles.
