Innovative Shaft Joint Approaches

Request Number N781521
Need details
Description

IncWell's partner seeks novel prop shaft joint technologies for usage on all-wheel drive vehicles.

 

Background

In all-wheel drive vehicles, the front axle drive shaft and transfer case are typically not aligned.

 

 

As a result, various joint approaches have been implemented:

  • universal joint
  • cardan joint
  • constant-velocity joint
  • rag (hardy spicer) joint

Unfortunately, these joints have serious drawbacks: cardan joints can transmit high torque but are complex, heavy and shows cardanic error (non uniformity of angular velocity). Hardy spicer is a simple and cheap joint but is only feasible for small bending angle and low torque transmitted due to heating of elastomer.

 

Consequently, IncWell's partner desires new technologies that can provide a lightweight, cost effective joint concepts that can deliver high torque.

Key Success Criteria
  • Simple manufacturability
  • Lighter and cheaper than established joints
  • Package analog to existing systems
  • Cost-effective
    • cost neutral is ideal

 

Additionally, the joint should meet the following performance:

  • Bending angle: approx. ± 4°
  • Maximum torque: approx. 1600Nm
  • Continuous torque: approx. 500Nm

 

Possible Approaches

All innovative concepts are welcome.

 

Approaches not of interest

None.
