Kentucky Patent of the Month – December 2021

A bell housing is a part of a vehicle’s transmission which covers the flywheel and the clutch or torque converter. It provides an area for controlling the power transfer from the motor to the attachment. Vehicle engines use a rotating engine to generate power which needs to be transferred to the transmission. With a bell housing, this transfer is more efficient and reduces energy loss.

The bellhousing is attached to the motor with taps. The taps are placed in tapped holes, wherein the pattern varies from manufacturer to manufacturer and from motor type to motor type. 

Accel Performance Group, LLC has been designing and manufacturing performance fuel and ignition systems for decades. To expand this line of ultra performance products, Accel has developed a universal bellhousing. This design is made to be adaptable to nearly any engine and transmission combinations while maintaining a high degree of strength and flexibility.

Their bellhousing is formed with a sheet of metal into a cone shaped housing with a flange extending out. A plate is attached to the other end of the cone. This plate attaches the bellhousing to the transmission and is the portion which can be machined and cut to accommodate any motor to transmission combination. Their design utilises high strength alloys formed in a spin forming machine – a true technological advance in metallurgy.

Another advancement with this technology is the fact that their bellhouse does not require the development of forms – a typically time consuming process which requires a hefty upfront capital investment. The bell housing can be formed just with a steel plate. The spin forming step removes any residual stresses. These two factors increase the safety factor of the bell housing even further.
