Hereinafter, with reference to the accompanying drawings, it will be described in detail with respect to the vehicle having an auxiliary braking device according to an embodiment of the present disclosure.

1 is a view illustrating an exterior of a vehicle provided with an auxiliary braking device according to an example of the present disclosure.

Referring to FIG. 1, a vehicle 100 includes a vehicle body 110 forming an exterior thereof, and a chassis including a power device, a steering device, and a braking device for generating power applied to the vehicle body 110.

Here, the braking device stops the vehicle 100 by reducing the rotational speed of the wheel 120 by applying a friction force to the wheel 120 that is rotationally driven by hydraulic pressure.

Since the braking force by the hydraulic pressure is limited, the time for braking increases in proportion to the rotational speed of the wheel 120, and as a result, the braking distance increases.

In particular, it is known that the braking distance is more than doubled in a situation where the friction force between the ground and the wheel 120 is reduced, such as snow and rain.

In the present example, the auxiliary braking device 130 is for minimizing the braking distance of the vehicle when sudden braking is required, such as a collision risk, or in bad weather such as snow or rain. 120 is preferably provided on the surface (hereinafter, referred to as the 'wheel cover surface 110a').

2 and 3 are views showing a state before and after the operation of the auxiliary braking device according to an embodiment of the present disclosure.

2 and 3, in this example, the auxiliary braking device 130 includes a support frame 131 and a braking plate 132.

The support frame 131 may be provided in an axial shape or a plate shape, and one end 131a is rotatably fixed to the wheel cover surface 110a. That is, it is preferable to be axially coupled.

The direction of the axis is provided so that the support frame 131 can be rotated on the same plane as the wheel 120. That is, the axial direction is preferably provided in parallel with the rotation center axis of the wheel (120).

On the other hand, the other end 131b of the support frame 131 is selectively detachably coupled to another position of the wheel cover surface 110a, and when sudden braking is required, such as a collision risk, or in bad weather such as snow or rain. It is provided so that the coupling can be released by the driver's operation.

Here, the release of the coupling may be made by various methods such as an electrical signal or mechanical operation.

For example, while the other end 131b of the support frame 131 is hooked to the wheel cover surface 110a, the hook coupling is released while the hook holding position is changed by an electrical signal generated by the driver. It may be provided to be.

Meanwhile, the braking plate 132 is rotatably provided at the other end 131b of the support frame 131.

Therefore, the braking plate 132 is preferably coupled to the support frame 131, the direction of the axis is preferably provided in parallel with the direction of the axis in which the braking plate 132 is coupled to the wheel cover surface (110a). .

As a result, the braking plate 132 is inserted between the wheel 120 and the ground by inertia when the other end 131b of the support frame 131 is disengaged to improve the braking force.

Specifically, the braking plate 132 is inserted between the wheel 120 and the ground, is grounded to the ground by the load of the vehicle body 110, and the sliding friction movement is to the wheel for rolling friction movement and sliding friction movement In comparison, the holding power is improved.

On the other hand, in this example, the support frame 131 and the braking plate 132 is the front of the vehicle body 110 relative to the wheel 120 so that the braking plate 132 is inserted between the wheel 120 and the ground by inertia. It is preferably located on the side.

In addition, the lower surface of the braking plate 132 in contact with the ground is preferably provided with a plurality of projections 133 are embedded in the ground to improve the braking force.

In detail, the plurality of protrusions 133 may be formed of a material having a greater hardness than the material of the ground (eg, asphalt, concrete, etc.).

In addition, the braking plate 132 is preferably provided with an elastic member that is elastically deformed by the load of the vehicle body 110 to improve the grounding force with the ground.

On the other hand, in this example, the auxiliary braking device 130 may be provided on all four wheels, but is preferably provided on two wheels to which the driving force is transmitted from the engine, in this case the operation of the auxiliary braking device 130 Is controlled to proceed simultaneously.

4 is a view showing a modification of the braking plate according to the present disclosure.

Referring to FIG. 4, the braking plate 132 is provided to have a lower surface contacting the ground and being provided flat, and an upper surface contacting the wheel 120 and having an arcuate vertical cross section.

Specifically, the braking plate 132 is preferably provided so that the thickness gradually becomes thinner in the direction inserted between the wheel 120 and the ground.

As a result, the braking plate 132 performs a wedge function with respect to the moving direction of the vehicle body 110, and thus the braking force may be further improved.

5 is a view showing another example of the auxiliary braking device according to the present disclosure.

Referring to FIG. 5, except that the auxiliary braking device 130 according to the present embodiment further includes a roller frame 134, the auxiliary braking device 130 is substantially the same as the above-described example. The description is replaced with the previous description.

In this example, the roller frame 134 connects the support frame 131 and the braking plate 132, and has the other end 131b of the support frame 131 detachably fixed to the wheel cover surface 110a. ) Is provided.

In addition, the braking plate 132 is coupled to the roller frame 134.

The roller frame 134 includes a roller body 134a and a coil spring member 134b.

The roller body 134a is pivotally coupled to the other end 131b of the support frame 131, and the direction of the axis thereof is provided in parallel with the direction of the axis where the brake plate 132 is coupled to the wheel cover surface 110a. It is preferable.

The coil spring member 134b is wound around the roller body 134a, and one end 131a is fixed to the roller body 134a, and the other end 131b is fixed to the braking plate 132.

As a result, since the position of the braking plate 132 can be expanded and contracted, the length of the support frame 131 can be shortened, and the braking plate 132 is inserted between the wheel 120 and the ground in the state where the braking plate 132 is inserted. An attractive force is applied to the 132 to maintain the contact state between the wheel 120 and the braking plate 132 to improve the grounding force between the bottom surface of the braking plate 132 and the ground.
