Abstract
A transport refrigeration system (1) includes a transportation refrigeration unit (37); a generator (11) connected to a wheel axle (7A) of the transport refrigeration system (1), the wheel axle (7A) being coupled to a wheel (5), wherein the generator (11) is configured to be driven to generate electricity by rotation of the wheel axle (7A) and to supply that electricity to the transportation refrigeration unit (37); and a damper (23) connected to the wheel axle (7A) between the wheel (5) and the generator (11). Short spikes or pulsations in torque along the wheel axle (7A) resulting from, e.g., harsh braking or wheel blocking can be, dampened, either wholly or partly, by the damper (23) such that damage to the transport refrigeration system (1) can be avoided.
Claims15
A transport refrigeration system (1, 10) comprising:
- a transportation refrigeration unit (37);
- a generator (11) connected to a wheel axle (7A) of the transport refrigeration system (1, 10), the wheel axle (7A) being coupled to a wheel (5), wherein the generator (11) is configured to be driven to generate electricity by rotation of the wheel axle (7A) and to supply that electricity to the transportation refrigeration unit (37);
- and
- a damper (23) connected to the wheel axle (7A) between the wheel (5) and the generator (11);
- wherein the damper is configured to dampen torque supplied along the wheel axle.
A method of assembling a transport refrigeration system (1, 10) comprising:
- providing a transportation refrigeration unit (37);
- connecting a damper (23) to a wheel axle (7A) of the transport refrigeration system (1), wherein the wheel axle (7A) is coupled to a wheel (5);
- connecting a generator (11) to the wheel axle (7A) such that the generator (11) is configured to be driven to generate electricity by rotation of the wheel axle (7A);
- and
- connecting the generator (11) to the transportation refrigeration unit (37) such that the generator (11) is configured to supply electricity to the transportation refrigeration unit (37);
- wherein the damper (23) is connected to the wheel axle (7A) between the wheel (5) and the generator (9);
- wherein the damper is configured to dampen torque supplied along the wheel axle.
A method of retrofitting a transport refrigeration system (1, 10) comprising:
- a transportation refrigeration unit (37);
- a generator (11) connected to a wheel axle (7A) of the transport refrigeration system, the wheel axle being coupled to a wheel (5), wherein the generator is configured to be driven to generate electricity by rotation of the wheel axle and to supply that electricity to the transportation refrigeration unit;
- the method comprising connecting a damper (23) to the wheel axle between the wheel and the generator;
- wherein the damper is configured to dampen torque supplied along the wheel axle.
