ABSTRACT

A Spanish small engineering company with a wide experience in mechanical product design is preparing a Eurostars proposal. The objective is developing an innovative bike transmission based on gears made of Polyphthalamide.

An electric bicycle manufacturer and a polymer manufacturer are sought to collaboratively design a plastic material which enables the production of a lighter shaft drive transmission for the bicycle.


FULL DESCRIPTION

• The project:

One of the systems that more affects the bike reliability is the transmission and currently, most of them are with the chain that presents important troubles due to its frequent derailments. How many bikers going at work have dirtied their hands fixing the derailed chain? The shaft drive transmissions now present in the market consist entirely of metal gears and aren’t used more due to their cost and weight.

The company is a product design and mechanical engineering firm, with experience in transmission and bike design, has detected the opportunity to improve the existing shaft drive transmissions substituting the metal of the gears with Polyphthalamide (PPA), an advanced plastic material. Gears made of PPA weigh less than metallic ones and permit a 50% cost reduction.

The objective of the project is to produce a chainless bike transmission made of advanced materials which use a driven shaft instead of a chain to transmit power from the pedals to the wheel. It is based on a shaft and gears made of advanced polymer material, a reliable, light and cheap solution that integrates a torque sensor for electric-assisted bikes.

The SME has already made and tested a prototype, but it is necessary to test different combinations of polymers and plastic materials to improve the injection processes. Besides, it is necessary to define the specifications and design to integrate the transmission to the bicycle.
