It is obscured by 19.

Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

The present invention can apply torque to a plurality of wheel nuts (6) that are loosened or fastened by a plurality of bolts (3) at the time of fastening and disassembling the tire (4) can be greatly improved workability, which of the present invention A case where the wheel nut 6 is fastened using the torque device 10 will be described in detail.

That is, after the wheels 5 on which the tires 4 are mounted are coupled to the plurality of bolts 3 protruding from the brake plate 2 in the assembly line (or when replacing the vehicle tires), the wheels 5 The torque device 10 is positioned in a state in which the wheel nuts 6 are respectively fastened to the protruding bolts 3.                     

Subsequently, the driven member 13 of the torque device 10 is positioned with the wheel nut 6, that is, the wheel nut 6 is coupled to the jig 13b of the driven member 13, and then the torque device 10 When a rotational force is applied to the head 11a 'portion of the driving member 11 constituting the drive by using a wrench or a power tool R, as shown in FIG. 2, the driving member 11 torques the tool R. As shown in FIG. While rotating by (T, Torque), the drive gear 11b coupled to the end of the drive shaft 11a is rotated to generate torque T 'in the same direction.

At this time, the wheel nut 6 is positioned by the magnet 14 provided at the end of the jig 13b of the driven member 13. That is, the wheel nut 6 is positioned on the magnet 14 of the jig 13b. ) In the fastened state, the wheel nut 6 is not moved by the magnetic force of the magnet 14, and thus the fastening operation is easy.

As such, when the driving gear 11b of the driving member 11 is rotated, the transmission gears 12a and 12a 'of the transmission member 12 formed in respective directions engaged with the driving member 11b are first and second support links 12b and 12c. While rotating freely via), the torque T 'is generated in a direction opposite to the torque T' of the drive gear 11b, and then to the transmission gears 12a and 12a 'of the transmission member 12. The driven gear 13c of the driven member 13, which is engaged with each other, generates a torque T '' in a direction opposite to the torque T ', thereby rotating the driven shaft 13a to engage the jig 13b. ) Will rotate.

Subsequently, when the wheel nut 6 is rotated on the bolt 3 by the torque T ″ of the driven member 13, the wheel nut 6, which is respectively fastened to the bolt 3, is the bolt 3. Advancing toward the wheel 4, the wheel 5 on which the tire 4 is mounted is firmly coupled to the brake plate 2. That is, a plurality of wheel nuts 6 each fastened to the plurality of bolts 3 with one operation. Can be tightened at the same time.

In addition, in order to separate the wheel nut 6 to replace the tire 4, the jig 13b of the driven member 13 constituting the torque device 10 of the present invention is coupled to the wheel nut 6, respectively, as described above. When the driving member 11 is rotated using the tool R in the opposite direction, the torque of the tool R is transmitted through the driving gear 11b, the transmission gears 12a, 12b, and the driven gear 13c. Of course, the plurality of wheel nuts 6 are released at the same time while being sequentially transmitted.

Meanwhile, when the wheel nut 6 is fastened to the bolt 3 by using the torque device 10, the torque T ″ generated by the wrench or the power tool R is transmitted through the torque checking means 15. The naked eye of the operator, that is, the engaging groove 17a of the torque indicator 17 coupled to the support plate 16 forming the torque checking means 15 is formed in the drive shaft 11a of the drive member 11. Push them toward the coupling boss 11a "so that they fit together.

As such, the torque indicator 17 is rotated together with the drive member 11 coupled to the drive shaft 11a of the drive member 11 and rotated by a tool, wherein the torque indicator 17 is shown in FIG. 2. As described above, the guide channel 17c fitted to the protruding guide protrusion 16b of the support plate 16 is rotated in the opening surface 16a of the support plate 16.

Subsequently, the torque indicator 17 is rotated in dependence on the torque reaction part so that the torque applied through the tool can be accurately known. That is, the torque indicator 17 is pulled while tensioning the elastic member 20 forming the torque reaction part. The slide is rotated while sliding along the guider 18, and the torque pointer 17d moves in the torque scale 16c indicated on the support plate 16 as the torque indicator 17 rotates.

In this case, the position indicated by the torque scaler 17d of the torque indicator 17 at the torque scaler 16c is a torque value corresponding to the torque T applied to the driving member 11 through the tool. On the torque T applied according to the elasticity modulus of the elastic member 20 which prevents the rotation of the indicator 17 and the friction rate between the fracturer 17b of the torque indicator 17 and the frictional guider 18 causing friction. Of course, after the fastening of the wheel nut 6 is completed, the support plate 16 and the torque indicator 17 forming the torque checking means 15 are moved to the drive shaft 11a of the drive member 11. When pushed in), the coupling groove 17a of the torque indicator 17 is separated from the coupling boss 11a "formed on the drive shaft 11a.

As such, when the torque T is not transmitted to the torque checking means 15, the elastic member 20 is restored to the initial value and at the same time, the torque indicator 17 is also returned to the initial state.

As described above, according to the present invention, the torque generated by the wrench or the power tool is made up of a plurality of gears so as to act simultaneously on the plurality of wheel nuts. Since the separation is performed at the same time, the convenience of the work is improved.                     

In addition, the present invention can visually check the torque amount applied to the wheel nut when disassembling or fastening the tire with the naked eye, so that there is an effect of not applying excessive torque when tightening the wheel nut.
