Field of the Invention [0001] The present invention relates to a vehicle auxiliary wheel, and more particularly, to an auxiliary wheel for a vehicle, which is mounted on a wheel of a vehicle such as a tractor and is provided with an auxiliary wing that can be folded through a user's operation, The present invention relates to a vehicle auxiliary wheel capable of smooth operation and capable of quickly moving the auxiliary wing in a folded state during normal driving.

Generally, a tractor is a vehicle that performs various operations using a pulling force, and is mainly used for agricultural or construction purposes.

The structure of the tractor is basically the same as that of a regular car, but it is equipped with a powerful engine, making it strong and robust.

In particular, tractors have developed for agricultural use and are still essential equipment for farming to haul plows, harrows, harvesters, etc. for cultivation.

Such tractors often work on soft grounds such as rice fields or mud fields, which are more watery than hard ground for their use.

In this case, due to the weight of the tractor, even when the wheels of the tractor are slightly out of the ground, a lot of power is consumed to proceed. In some cases, the wheels are idling and damage the ground, .

In order to solve this problem, a technique of providing a supplementary wheel with teeth on the wheels of the tractor so as to prevent the tractor from proceeding regardless of the conditions of the work surface is disclosed in Utility Model No. 20-1995-0010401 13), and Utility Model No. 20-1996-0005248 (published on June 24, 1996).

This is to ensure that the guide pin 332 is stably supported horizontally on the extended portion 331b in a state in which the auxiliary wing 20 is completely folded and unfolded. So that the auxiliary vane 20 can be prevented from flowing in a fully raised and folded state.

The elevating and lowering converting means 34 is configured such that the moving plate 31 is raised with respect to the base portion 10 while the cylinder rod 322 is retracted to the cylinder body 321, And is configured to connect the cylinder rod 322 and the moving plate 31 to each other, and includes a conversion plate 341 and a separation supporting rod 342 in one embodiment of the present invention.

The conversion plate 341 is disposed in parallel with the moving plate 31 in a direction opposite to the direction of the moving plate 31 with respect to the base portion 10, Lt; / RTI >

The spacer rod 342 connects the conversion plate 341 and the moving plate 31. The spacer rod 342 is connected to the conversion plate 341 according to the forward / backward movement of the cylinder rod 322, And the moving plate 31 are integrally lifted and lowered.

The spacing support bar 342 passes through the bar through hole 126 of the base plate 12 and is guided in the longitudinal direction by the elevation guide block 127 as described above.

5, when the auxiliary wing 20 is unfolded, the auxiliary wheel of the automobile according to the present invention is rotated by the cylinder body 321 So that it is possible to prevent the cylinder rod 322 from being contaminated by soil or the like when working on a soft ground such as a rice field or a muddy field.

The safety catch 35 is configured to restrain the movement of the moving plate 31 when the auxiliary vane 20 is folded. The latch hinge shaft 351, the elastic spring 352, the guiding inclined surface 353, And a latching jaw 354.

The latch hinge shaft 351 rotatably connects one end of the safety latch 35 to a latch support 125 provided on the base plate 12.

6, the elastic spring 352 is inserted through the latch insertion hole 313 formed in the moving plate 31 so that the distal end of the safety latch 35 is engaged with the distal end of the safety latch 35, The safety latch 35 is elastically supported in a direction in which the latching jaw 354 formed on the moving plate 31 can be caught by the moving plate 31. [

The guiding inclined surface 353 is lowered with respect to the base portion 10 by the elastic spring 352 and the movable plate 31 is lowered with respect to the base portion 10, When the safety latch 35 is in contact with the moving plate 31 in the process of passing through the latch insertion hole 313 formed in the elastic plate 352, The contact surface with the moving plate 31 is inclined so that the rotation is induced in a direction opposite to the supporting direction.

6, the tip of the safety catch 35 is connected to the moving plate 31. The safety catch 35 is provided at the distal end of the safety catch 35, The safety catch 35 is rotated in one direction by the elastic spring 352 while being hooked on the moving plate 31 in a state that the safety latch 35 passes through the formed latching hole 313 to restrict the movement of the moving plate 31 .

By the construction of the safety catch 35 for restraining the movement of the moving plate 31 in a state in which the auxiliary vane 20 is folded, the centrifugal force due to the rotation of the wheel 1 causes the auxiliary vane 20 20 can be prevented from being unfolded.
