A spare tire winch mechanism, which comprises a rope winding assembly which enables the spare tire be taken out of its location and which enables the winding of the rope, to which the spare tire is connected, in upwards and downwards directions by being rotated by tire wrench, in order to locate the flat tire in the same location from which the spare tire is taken out, a spiral pipe which keeps the rope inside its body, a rope fixation bearing enabling the spare tire connect to the end of the rope, comprising; • a carrier body which forms a bearing the components of rope winding assembly inside it and protects these against external factors, • a front cover, which covers the front side of the said carrier body, characterized by further comprising; • a moment shaft which is rotated by the tire wrench and is formed a bearing to the space in the middle of a worm gear, • the worm gear, which is located between the moment shaft and a threaded drum, which is rotated by the moment shaft that it is connected to and enables the threaded drum rotate by transmitting the rotation movement to the threaded drum, • the threaded drum which has helical gears on its body and winds the rope on its body by rotating by the rotating movement that it receives from the worm gear it is connected to, • a internal bearing, which is located between the moment shaft and worm gear, which transmits the rotating movement of the moment shaft to the worm gear by the gears on its body, which enables the moment shaft rotate idle by sliding downwards and disconnects the moment shaft from the worm gear in order to protect the mechanism parts in case an extreme moment is applied to the moment shaft, • a pressure spring which is connected to the said internal bearing from the bottom and which enables the internal bearing remain in contact between the moment shaft and worm gear by pushing the internal bearing upwards and which enables the internal bearing slide downwards by being stuck in case an extreme moment is applied to the moment shaft, • a holder plate, which is located between the carrier body and the worm gear, which enables the contact of the gear parts by pushing the worm gear towards the threaded drum and keep a tension spring in tension position when it is located and which enables the spare tire, which is connected to the rope wound to the drum gear body, to be lowered to the vehicle floor by its own weight when it is dislocated, • the tension spring which is located between the carrier body and the moment shaft and which disconnects the worm gear from the threaded drum by spring force when the holder plate is dislocated. • a carrier body which forms a bearing the components of rope winding assembly inside it and protects these against external factors, • a front cover, which covers the front side of the said carrier body, characterized by further comprising; • a moment shaft which is rotated by the tire wrench and is formed a bearing to the space in the middle of a worm gear, • the worm gear, which is located between the moment shaft and a threaded drum, which is rotated by the moment shaft that it is connected to and enables the threaded drum rotate by transmitting the rotation movement to the threaded drum, • the threaded drum which has helical gears on its body and winds the rope on its body by rotating by the rotating movement that it receives from the worm gear it is connected to, • a internal bearing, which is located between the moment shaft and worm gear, which transmits the rotating movement of the moment shaft to the worm gear by the gears on its body, which enables the moment shaft rotate idle by sliding downwards and disconnects the moment shaft from the worm gear in order to protect the mechanism parts in case an extreme moment is applied to the moment shaft, • a pressure spring which is connected to the said internal bearing from the bottom and which enables the internal bearing remain in contact between the moment shaft and worm gear by pushing the internal bearing upwards and which enables the internal bearing slide downwards by being stuck in case an extreme moment is applied to the moment shaft, • a holder plate, which is located between the carrier body and the worm gear, which enables the contact of the gear parts by pushing the worm gear towards the threaded drum and keep a tension spring in tension position when it is located and which enables the spare tire, which is connected to the rope wound to the drum gear body, to be lowered to the vehicle floor by its own weight when it is dislocated, • the tension spring which is located between the carrier body and the moment shaft and which disconnects the worm gear from the threaded drum by spring force when the holder plate is dislocated.
