Description
WHEEL BALANCE WEIGHT FOR A VEHICLE
BACKGROUND OF THE INVENTION
Field of the invention
The present invention relates to a wheel balance weight installed in a
certain portion of an edge portion of a wheel for correcting a unbalance of a tire
wheel, and in particular to a wheel balance weight for a vehicle which is capable of
separately forming a weight and a clip which fixedly supports the weight to a wheel
and integrating engaging the same for thereby enhancing a productivity and
durability of a product.
Description of Related Art
Generally, in the case of a tire wheel of a vehicle, if there is a unbalance in
a weight, a vibration occurs due to a centrifugal force based on a revolution.
Therefore, a noise and eccentric friction and handle trembling problem occur.
Since the centrifugal force is in proportion to a revolution, in the case that when a
vehicle runs at a high speed, a wheel balance should be corrected.
The wheel balance is classified into a -static balance and a dynamic
balance. If the static balance is not fixed, a wheel is vibrated up and down, and if
the dynamic balance is not fixed, a wheel is vibrated in the left and right directions.
In order to correct the unbalance of a vehicle wheel, a certain balance
weight having a certain weight is installed in a certain portion(an opposite portion
where a weight unbalance occurs) of an edge portion of a wheel for thereby
implementing a balance by forming a centrifugal force in the opposite direction.
As shown in Figure 1 , in the typical construction of a wheel balance weight
for a vehicle, a weight 2 formed of lead is integrally engaged to a clip inserted in
an edge portion of a tire wheel based on a casting work.
However, in the above wheel balance weight for a conventional vehicle,
since a weight is formed integrally with a clip by a casting work, a lead having a
good casting property is generally used as a material for a weight based on a
characteristic of a casting work, the strength of the same is weak. Therefore, in the
case that a lead weight is engaged to a wheel, the weight of a balance weight is
easily changed or damaged. In addition, the fabrication cost of the product is
increased due to a difficult casting work. Furthermore, an environmental problem
may occur due to a lead component which is a material of a weight.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a wheel
balance weight for a vehicle which is capable of separately forming a weight and a
clip which fixedly supports the weight to a wheel and integrating engaging the
same for thereby enhancing a productivity and durability of a product and
implementing a stable engagement between a weight and a clip.
It is another object of the present invention to provide a wheel balance
weight for a vehicle which is capable of preventing an environmental problem by
using a steel as a material of a weight compared to the conventional art in which a
weight is formed of lead.
In order to achieve the above objects, there is provided a wheel balance
weight for a vehicle which includes a weight which includes an engaging
protrusion in an outer portion and a concave groove formed in a surrounding
portion of the engaging protrusion, and a clip which includes a hook portion fixed
to an edge portion of a tire wheel and an engaging portion which is extended from
the hook portion and has an engaging hole through which an engaging protrusion
of the weight passes, an edge portion of the engaging hole being bent at a slant
angle in an inner side for thereby being inserted into the concave groove of the
weight, for thereby adjusting a unbalance of the tire wheel.
In order to achieve the above objects, there is provided a wheel balance
weight for a vehicle which includes a weight which has a fixing concave groove
formed in an outer portion of the same, and a clip which includes a hook portion
fixed to an edge portion of a tire wheel, and an engaging portion which is extended
from the hook portion and bent to support an outer portion of the weight and
includes a fixing protrusion corresponding to a fixing concave groove of the weight,
for thereby adjusting an unbalance of the tire wheel.
In order to achieve the above objects, there is provided a wheel balance
weight for a vehicle which includes a weight which has a through h'ole through
which an engaging member passes, and a clip which includes a hook portion
inserted into an edge portion of a tire wheel and an engaging portion which is

DETAILED DESCRIPTION OF PREFFERED EMBODIMENTS
The constructions, features and operations of a wheel balance weight for a
vehicle according to the present invention will be described with reference to the
accompanying drawings.
[First embodiment]
As shown in Figures 2A through 2F, a wheel balance weight for a vehicle
according to a first embodiment of the present invention includes a weight 10
having a protruded engaging protrusion 12 in an outer portion of the same, and a
clip 20 which has a hook portion 21 fixed to an edge portion of a tire wheel, and an
engaging portion 22 which is extended from the hook portion 21 and includes an
engaging hole 23 through which the engaging protrusion 12 of "the weight 10
passes.
The weight 10 has a certain weight and is installed in a certain portion(an
opposite portion where a weight unbalance occurs) of a tire wheel and has a
certain curve corresponding to an edge portion of a tire wheel. An insertion groove
11 is formed in an outer portion so that an engaging portion 22 of the clip 20 is
inserted, so that the movement of the engaging portion 22 is limited in the left and
right directions. A transfer groove 13 is formed in a lower portion of the same, so
that a transfer is uniformly implemented when the transfer is implemented in the
direction of a work table 120 from an input hopper 150(which will be described
later) through a transfer line 130.
At this time, the weight 10 has various weights for thereby selecting a
certain weight based on a weight unbalance of the tire wheel. The material of the
weight 10 is generally a steel which does not has an environmental problem. In a
certain case, a stainless material or a certain heavy material may be used.
The engaging protrusion 12 is integrally protruded from the bottom of the
insertion groove 11 and passes through an engaging hole 23 of the engaging
portion 22 and is pressure-expanded for thereby engaging the weight 10 and the
clip 20. The cross section of the same is elliptical. A concave groove 14 slanted in
an inner side is formed in the surrounding portions of the same. In addition, as
shown in Figure 2F, the engaging protrusion 12 is protruded from a portion(line b)
distanced' from a center line of the weight 10 by a certain distance "t" in an upper
direction for thereby maintaining a certain distance from the transfer groove 12
formed in the lower portion of the weight 10.
Since the transfer groove 13 is formed in the lower portion of the weight 10,
and the engaging protrusion 12 is protruded in an upper direction from the center
line of the weight 10, the weight center of the w.eight 10 is in an eccentric portion in
the upper direction.
The engaging hole 23 formed in the engaging portion 22 of the clip 20 is
formed in an elliptical shape for thereby corresponding to the engaging protrusion
12 of the weight 10, and the weight 10 and the engaging portion 22 do not idle-
rotated after the engaging protrusion 12 passes through the engaging hole 23.
In addition, as shown in Figures 2B through 2E, the edge portion of the
engaging hole 23 is bent in a shape slanted in the inner side in order for the same
to be inserted into the concave groove 14 of the weight 10, so that the end portion
of the engaging protrusion 12 is pressure-expanded for thereby implementing a
stable and strong engagement when the weight 10 and the engaging portion 22
are engaged.
As shown in Figures 3A through 3C, the fabrication apparatus 100 capable
of engaging the weight and clip according to a first embodiment of the present
invention includes a circular work table 120 which is rotatably installed on an upper
portion of the body 110 and on which the weight 10 and the clip 20 are engaged, a
pair of input hoppers 150 and 160 which are distanced from the work table 120
and transfer the weight 10 and the clip 20 to the work table 120 through the
transfer lines 130 and 140, and a forging unit 170 which is installed on an upper
portion of the body 110 for thereby stably engaging the weight 10 and the clip 20
by pressurizing the end portion of the engaging protrusion 12 of the weight 10.
At this time, the input hoppers 150 and 160 transfer the weight 10 and the
clip 20 to the work table 120 through the transfer lines 130 and 140 by a vibration
which occurs when driving a vibration motor(not shown) installed therein.
The weight 10 should be transferred in a state that the engaging
protrusion 12 is in an upper direction, so that it is engaged with the clip 20 in the
next process. A first selection unit 131 is installed in the transfer line 130 which
transfers the weight 10 from the input hopper 150 to the work table 120 for thereby
dropping the weight 10 into the input hopper 150 and performing a selection
operation in the case that the engaging protrusion 12 of the weight 10 is in the
direction of the bottom.
•Namely, since the engaging protrusion 12 is in a lifted state from the
bottom due to the engaging protrusion 12 in the case that the engaging protrusion
12 is in the direction of the bottom in such a manner that the engaging protrusion
12 is protruded from the surface, the weight 10 is naturally dropped along the cut
surface 131a of the first selection unit 131
In addition, since the weight 10 is formed in a curved shape to correspond
with the shape of the edge of the tire wheel, the weight 10 should be transferred in
the same direction during the transfer for thereby being properly engaged with the
clip 20 on the work table 120. A second selection unit 132 is formed on the
transfer line 130 for dropping the weight above which the transfer groove 13 is
positioned, among a plurality of weights 10 which are first selected by the first
selection unit 131 into the input hopper 150 and selecting the same secondarily
based on the construction that a drop hole 132a is formed in a slant line direction
on the transfer line 130 in the center portion of the same.
Namely, in the case that the transfer groove 13 is positioned in the upper
portion when passing through the second selection unit 132, -since the weight
center is located in the lower portion, the weight 10 is naturally dropped through
the drop hole 132a of the second selection unit 132. In addition, in the case that
the transfer groove 13 is positioned in the lower portion, since the weight center is
positioned in the upper portion, the weight 10 is not dropped through the drop hole
132a of the second selection unit 132, but is transferred to the work table 120.
The operation that the weight and clip are engaged by the fabrication
apparatus will be described.
First, when the vibration motor of the weight input hopper 150 is driven,
the weight 10 is transferred along the transfer line 130 by the vibrations generated
when driving the vibration motor. At this time, the weights 10 are selected by the
first selection unit 131 and the second selection unit 132 based on a continuous
transfer operation.
When the weight 10 is transferred to the work table 120, the work table
120 is rotated, and the clip 20 is inserted into the engaging protrusion 12 of the
weight 10, and an end portion of the engaging protrusion 12 is pressure-expanded
by a pressurizing pressure of the forging unit 170, so that the weight 10 and the
clip 20 are stably engaged and discharged to the outside in the next process.
In the wheel balance weight for a vehicle which is implemented based on
the above construction and work process, the engaging protrusion 12 formed in
the weight 10 passes through the through hole 23 of the engaging portion 22, and
an end portion of the same is pressure-expanded, so that the weight 10 and the
clip 20 are engaged. Since the engaging protrusion 12 is formed in an elliptical
shape, the weight 10 and the clip 20 are not idle-rotated, so that the weight 10 and
the clip are stable engaged. The concave groove 14 is formed in an edge portion
of the engaging protrusion 12 at a certain slant angle in the direction of the inner
side. In addition, since the edge portion of the engaging hole 23 of the engaging
protrusion 12 is curved at a slant angle in the direction of the inner side in order for
the edge portion of the same to be inserted into the concave groove 14 for thereby
implementing a stable engagement of the weight 10 and the clip 20. In addition,
since the end portion of the pressurized engaging protrusion 12 is fully embedded
in the engaging hole 23 when the end portion of the same is pressure-expanded
for thereby preventing any damage in the surface of the wheel when it is engaged
to the tire wheel.
[Second embodiment]
As shown in Figures 4A through 4C, in the wheel balance weight for a
vehicle according to the second embodiment of the present invention, a pair of
engaging protrusions 12' each having a circular cross section are protruded in the
insertion groove 11 of the weight 10 at a certain distance therebetween in the right
and left directions, and a pair of the engaging holes 23' corresponding to the
engaging protrusions 12' of the weight 10 are formed in the engaging portion 22.
In addition, the concave grooves 14' which are smoothly slanted in the
direction of the inner side are formed in the surrounding portion of the engaging
protrusion 12', and the edge portion of the engaging hole 23' of the engaging
portion 22 is slanted in the direction of the inner side in order for the same to be
inserted into the concave groove 14'.
In the thusly constituted second embodiment of the present invention,
since a pair of the engaging protrusions 12' which engage the weight 10 and the
engaging portion 22 of the clip 20 are protruded at a certain distance
therebetween in the left and right directions, the weight 10 and the clip 20 are not
idle-rotated for thereby implementing a stable engagement in the same manner as
the first embodiment of the present invention.
[Third embodiment]

portion of a tire wheel and an engaging portion 22' which is extended from the
hook portion 21 and is bent for supporting an outer portion of the weight and
includes a fixing protrusion 24 corresponding to the fixing concave groove 15 of
the weight.
The fixing protrusion 24 of the engaging portion 22' is inwardly protruded
by pressurizing an outer side of the engaging portion 22'. In another embodiment
of the present invention, the same may be integrally protruded from an inner
portion of the engaging portion 22 based on the molding method. In addition, the
fixing protrusion 24 is partially protruded from an inner side of the engaging portion
22'. In another embodiment of the present invention, the same may be
longitudinally protruded from an inner side of the engaging portion 22' in the left
and right directions, and the fixing concave groove of the weight 10 may be
extended in the left and right directions for thereby corresponding to the fixing

and implementing a stable engagement of the weight and clip.
In addition, since the material of the weight is steel, it is possible to
prevent an environmental problem due to the weight which is conventional formed
of lead.
RO/KR 05.03.2003
In addition, since the transfer groove is formed in the bottom of the weight,
it is possible to implement a continuous transfer of the dame in a certain type
when the weights are transferred from the hopper to the work line through the
transfer line for thereby implementing a mass production.
