Energy harvesting system for a vehicle |
| 摘要 |
An energy harvesting system includes a heat engine and a component. The heat engine includes a belt, a first member, and a second member. The belt includes a strip of material and at least one wire at least partially embedded longitudinally in the strip of material. The wire includes a shape memory alloy material. A localized region of the at least one wire is configured to change crystallographic phase between martensite and austenite and either contract or expand longitudinally in response to exposure to a first temperature or a second temperature such that the strip of material corresponding to the localized region also contracts or expands. The first member is operatively connected to the belt and moves with the belt in response to the expansion or contraction of the belt. The component is operatively connected to the first member such that movement of the first member drives the component. |

1. A belt for a heat engine comprising:
a strip of material including a plurality of discrete sections disposed in spaced relationship to one another and extending longitudinally and presenting a first side and a second side, opposing the first side; wherein the strip of material forms a continuous loop; at least one wire extending longitudinally between the discrete sections such that the at least one wire is exposed; wherein the at least one wire is further defined as extending circumferentially about the continuous loop of the strip of material to form a coil; wherein the at least one wire includes a shape memory alloy material; wherein a localized region of the at least one wire is configured to change crystallographic phase from martensite to austenite and thereby contract longitudinally in response to exposure to a first temperature such that the strip of material corresponding to the localized region of the at least one wire also contracts; and wherein the localized region of the wire is also configured to change crystallographic phase from austenite to martensite and thereby expand longitudinally in response to exposure to a second temperature such that the strip of material corresponding to the localized region of the at least one wire also expands.
