Automobile spare tire guy cable driving gear anti-rotating device

Abstract

The invention discloses an automobile spare tire guy cable driving gear anti-rotating device which is characterized in that a driving gear (3) is engaged with a driven gear (4); the driving gear (3) is sleeved on a rotating shaft (2); one end of the rotating shaft (2) extends out of a housing (1); an anti-rotating pin (8) is arranged close to the driving gear (3); the anti-rotating pin (8) is hinged with the housing (1) through the rotating shaft (9); one end of the anti-rotating pin (8) extends into a teeth slot of the driving gear (3); fixing seats (10) are arranged symmetrically at both sides of the other end of the anti-rotating pin (8); and each fixing seat (10) is connected with the anti-rotating pin (8) through a torsion spring (11). The automobile spare tire guy cable driving gear anti-rotating device is simple in structure, easy to process and fabricate, convenient to assemble, low in manufacturing cost, stable and reliable in transmission, and convenient and labor-saving in operation, can be used for effectively reducing the labor intensity of assembly workers, greatly improving the assembling efficiency, and can be used for various types of automobiles.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an anti-rotation device for a spare tire cable driving gear on an automobile. Background technique [0002] Generally, a car will be equipped with a spare tire so that it can be used in rotation when the tire is blown out. Spare tire is usually fixed on the chassis of automobile by cable device, and existing cable device is made of housing, rotating shaft, drive disc device, driving gear, driven gear, anti-skid gear, eccentric wheel and cable etc., when When the rotating shaft is turned with a special wrench, the rotating shaft drives the driving disc device to rotate, and the driving disc device drives the eccentric wheel through the outer hexagonal cooperation, so that the eccentric wheel drives the driving gear to rotate, and the driving gear drives the driven gear and the anti-skid gear to make the driven gear rotate. The gears twist the cables together. Whe...

AI Technical Summary

Problems solved by technology

[0003] 1) The structure is complex, there are many parts, the processing is difficult, the assembly operation is cumbersome, and the production cost is high

[0004] 2) It is more laborious to turn the rotating shaft, which will increase the difficulty of installing and removing the spare tire

[0005] 3) It is necessary to use a special wrench to control the rotation of the rotating shaft, which has strict requirements on the tools, which will affect the convenience of the owner to replace the spare tire by himself.
