ABSTRACT:
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority of Korea patent Application No. 2000-32679, filed Jun. 14, 2000.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a frame body automotive vehicle, and more particularly to a frame mounting structure for frame body automotive vehicle adapted to reinforce a coupling strength relative to a coupled region between a chassis frame and a body frame of a frame body vehicle to improve durability of body and to lighten the body according to reduced number of parts.
2. Description of the Prior Art
Generally, body of a vehicle is classified into a monocoque body and a frame body, where the monocoque body adequately combines a body panel and frame to be shaped like a box for use mainly in passenger cars while the frame body comprises a chassis frame as a main skeleton of floor panel on which a body of a vehicle stands and is mainly used for heavy vehicles.
Meanwhile, as illustrated in
FIG. 1
, a body of vehicle comprising a frame body includes a chassis frame
10
having two oppositely facing frames each extended lengthwise, a cross member
12
comprising bars each arranged crosswise to connect the chassis frame
10
, body frames
14
each mounted at an upper side of the chassis frame
10
and a floor panel (depicted in
FIG. 2
) mounted on the body frame
14
.
The chassis frame
10
and the body frame
14
are coupled by screwing therebetween with the body frame
14
mounted on the chassis frame
10
as shown in
FIG. 2
defining an “A” shaped cross-section, where a through hole
10
a
centrally formed at the chassis frame
10
is installed thereon and thereunder with an upper bush
16
and a lower bush
18
, while another through hole
14
a centrally formed at the body fame
14
is inserted by a bolt
20
. The bolt
20
sequentially penetrates the upper bush
16
, the chassis frame
10
and the lower bush
18
to be coupled to a nut
22
at a bottom surface of the lower bush
18
.
Furthermore, the body frame
14
is installed thereon with a floor panel
24
on which there is formed a through hole
24
a
to allow hand tools to pass therethrough when the bolt
20
is coupled.
The through hole
24
a
formed on the floor panel
24
is assembled with a plug
26
to prevent the bolt
20
from being exposed outside when the bolt
20
is completed in coupling.
The chassis frame
10
and the body frame
14
respectively have a cross-sectional shape like “⊂”, and particularly, the body frame
14
is joined at an inner peripheral side thereof by a bent reinforcing member
28
having a same cross-sectional shape.
Meanwhile, the bolt
20
and the nut
22
for coupling the chassis frame
10
and the body frame
14
are assembled together with other coupling elements as shown in
FIG. 3
, where the bolt
20
and the upper bush
16
are mounted with a washer
30
therebetween while the upper bush
16
and the lower bush
18
are disposed with a pipe
32
therebetween. A spacer
34
and a washer
36
are respectively arranged between the upper bush
18
and the nut
22
.
At this time, load applied from outside while a vehicle is running is attenuated by the upper bush
16
and the lower bush
18
assembled between the chassis frame
10
and the body frame
14
to thereby reduce noise in the interior of the vehicle.
However, there is a problem in the frame-bodied vehicle thus described according to the prior art in that the bolt
20
sequentially penetrates the body frame
14
, the upper bush
16
and the lower bush
18
to be fastened by the nut
22
such that coupled strength between the chassis frame
10
and the body frame
14
is not sufficient.
There is another problem in that the chassis frame
10
tends to lean toward one side by inertia when a vehicle is abruptly braked or swiveled, causing a safety problem, and in a structure of frame-bodied vehicle thus described, the plug
26
assembled for concealing the through hole
24
a
is mounted on the floor panel
24
after the coupling of the bolt
20
, resulting in increase of manufacturing cost. There is still another problem in that each coupled area between the chassis frame
10
and the body frame
14
must be applied with the plug
26
, leading to a complicated assembly process and an increase weight of the vehicle.
SUMMARY OF THE INVENTION
The present invention is disclosed to solve the aforementioned problems and it is an object of the present invention to provide a frame mounting structure for frame body automotive vehicle constructed to constitute a double structure between a chassis frame and an upper bush and between the upper bush and a lower bush when the chassis frame and a body frame are assembled to improve a coupled strength between the chassis frame and the body frame and to promote running safety of the vehicle.
It is another object of the present invention to provide a frame mounting structure for frame body automotive vehicle constructed to assembly the chassis frame and the body frame under the body frame to shorten an assembly process according to exclusion of plug use.
In accordance with the objects of the present invention, there is provided a frame mounting structure for frame body automotive vehicle, the structure comprising:
a chassis frame arranged lengthwise;
a body frame assembled by way of screw coupling while an upper bush and a lower bush are mounted on the chassis frame;
a double coupling member fitted and fixed through the upper bush and the lower bush; and
coupling means fitted at an upper side of the double coupling member to be coupled to the double coupling member and fixed at the body frame.
