Abstract

The generation of electrical power for large-vehicle transport refrigeration units (TRU) such as semi-trailer reefers. A generator is mounted to the vehicle frame or axle carriage and driven by a wheel-pulley system. Translational motion of the heavy vehicle produces electrical power using the substantial momentum of the vehicle. The electrical power can also be supplemented by at least one solar panel mounted on the roof of the semi-trailer reefer.

Claims

1. A backup power generator for battery powered transport refrigeration units comprising in combination:

i. a first support housing, said first support housing having at least a top, an open front, and an open bottom;

ii. said support housing containing and supporting therein, a jackshaft, said jackshaft having a first pulley on one end and a second pulley on an opposite end;

iii. said first pulley being connected by a V-belt to a drive pulley, said drive pulley being located between two wheels of a semi-truck trailer, any tension on said V-belt being regulated by a spring loaded idler wheel impinging on said V-belt;

iv. a second support housing supporting a generator therein, said generator having a wide pulley on one end thereof, said wide pulley and said second pulley of said jackshaft being connected by a cog belt;

v. surmounted on said first support housing, a voltage regulator, wherein said voltage regulator is electrically connected to said generator;

vi. said voltage regulator being electrically connected to at least one battery.

2. The backup power generator for battery powered transport refrigeration unit as claimed in claim 1 wherein the unit is electrically supplemented by the use of at least one solar panel mounted on the top of a reefer that also has the battery powered transport refrigeration unit mounted on said reefer.
