Abstract

Claims (33)

1 . A power transfer mechanism ( 1 ) comprising:

a body ( 2 ) on a vehicle;

an engine (E) in the body ( 2 ) which enables the vehicle to move;

a shaft ( 3 ) on the body ( 2 ) which is activated by the engine (E);

a housing ( 4 ) containing the shaft ( 3 );

at least one bearing group ( 5 ) between the housing ( 4 ) wall and the shaft ( 3 ) which supports movement of the shaft ( 3 );

a sponge ( 6 ) located inside the housing ( 4 ) for absorbing and storing a fluid;

a trigger ( 7 ) that triggers and compresses the sponge ( 6 ) so that the fluid stored in the sponge ( 6 ) reaches the bearing group ( 5 ) by the effect of gravity and thereby allowing the bearing group ( 5 ) to be cooled and lubricated; and

a shaft wall ( 401 ) located in the housing ( 4 ) and surrounding the shaft ( 3 ) and a housing wall ( 402 ) containing the bearing group ( 5 ) and located on the housing ( 4 ) in connection with the shaft wall ( 401 ); wherein the sponge ( 6 ) is located between the shaft wall ( 401 ) and the housing wall ( 402 ), in an area between the shaft wall ( 401 ) and the housing wall ( 402 ), so as to contact the shaft wall ( 401 ) and housing wall ( 402 ) when compressed.

2 . The power transfer mechanism ( 1 ) according to claim 1 , wherein the bearing group ( 5 ) located opposite the sponge ( 6 ) so that the fluid moving from the sponge ( 6 ) by the effect of gravity is transferred to the bearing group ( 5 ).

3 . The power transfer mechanism ( 1 ) according to claim 1 , comprising at least one lubricating element ( 8 ) located on the housing ( 4 ) for the lubrication of the shaft ( 3 ) and/or bearing group ( 5 ); wherein the sponge ( 6 ) retains the fluid previously sent by a user from the lubricating element ( 8 ).

4 . The power transfer mechanism ( 1 ) according to claim 1 , wherein the sponge ( 6 ) has an almost annular form which at least partially surrounds the inner housing ( 401 ) and is located in a form-compatible manner in the housing wall ( 402 ).

5 . The power transfer mechanism ( 1 ) according to claim 1 , comprising at least one bottom cover ( 9 ) which has a perforated form in order for the fluid stored in the sponge ( 6 ) to reach the transmission group ( 5 ), wherein the bottom cover ( 9 ) is movable relative to the outer housing so that, as a volume of the trigger ( 7 ) increases, the bottom cover ( 9 ) presses and compresses the sponge ( 6 ).

6 . A power transfer mechanism ( 1 ), comprising:

a body ( 2 ) on a vehicle;

an engine (E) in the body ( 2 ) which enables the vehicle to move;

a shaft ( 3 ) on the body ( 2 ) which is activated by the engine (E);

a housing ( 4 ) containing the shaft ( 3 );

at least one bearing group ( 5 ) between the housing ( 4 ) wall and the shaft ( 3 ) which supports movement of the shaft ( 3 );

a sponge ( 6 ) located inside the housing ( 4 ) for absorbing and storing a fluid;

a trigger ( 7 ) that triggers and compresses the sponge ( 6 ) so that the fluid stored in the sponge ( 6 ) reaches the bearing group ( 5 ) by the effect of gravity and thereby allowing the bearing group ( 5 ) to be cooled and lubricated; and

at least one bearing ( 501 ) located in the bearing group ( 5 ) and providing support and at least one outer ring ( 502 ) surrounding the bearing ( 501 ); wherein the trigger ( 7 ) contacts the outer ring ( 502 ); wherein if a temperature of the bearing ( 501 ) reaches a threshold value predetermined by the manufacturer in case the lubricating element ( 8 ) fails to operate, volume of the trigger ( 7 ) is increased, thereby pressing and compressing the sponge ( 6 ).

7 . The power transfer mechanism ( 1 ) according to claim 6 , wherein the porous sponge ( 6 ) is made of aerogel which is capable of retaining fluid, thus transmitting the fluid therein to the bearing ( 501 ) when compressed, and allowing the bearing ( 501 ) to be lubricated and cooled.

8 . A power transfer mechanism ( 1 ), comprising:

a body ( 2 ) on a vehicle;

an engine (E) in the body ( 2 ) which enables the vehicle to move;

a shaft ( 3 ) on the body ( 2 ) which is activated by the engine (E);

a housing ( 4 ) containing the shaft ( 3 );

at least one bearing group ( 5 ) between the housing ( 4 ) wall and the shaft ( 3 ) which supports movement of the shaft ( 3 );

a sponge ( 6 ) located inside the housing ( 4 ) for absorbing and storing a fluid;

a trigger ( 7 ) that triggers and compresses the sponge ( 6 ) so that the fluid stored in the sponge ( 6 ) reaches the bearing group ( 5 ) by the effect of gravity and thereby allowing the bearing group ( 5 ) to be cooled and lubricated;

at least one lubricating element ( 8 ) located on the housing ( 4 ) for the lubrication of the shaft ( 3 ) and/or bearing group ( 5 ); wherein the sponge ( 6 ) retains the fluid previously sent by a user from the lubricating element ( 8 ); and

a stopper ( 10 ) with a perforated structure which is fixed to limit a movement of the sponge ( 6 ) and enables the fluid transferred from the lubricating element ( 8 ) towards the bearing group ( 5 ) by the effect of gravity to reach the sponge ( 6 ).
