ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a liquefied petroleum gas (LPG) tank assembly for a vehicle, and more particularly, the present invention relates to a liquefied petroleum gas tank assembly for a vehicle, which is able to solve the following two major problems that conventional LPG tanks have. One is induced in the conventional art in association with a height of the vehicle body from the ground when it is mounted to the undercarriage of a vehicle body. The other is possibility that a passenger compartment can be polluted with LPG when disposed in a trunk room.
2. Description of the Related Art
In a motor vehicle which uses LPG as fuel, a fuel tank for storing LPG is conventionally manufactured in a manner such that it has a cylindrical structure while meeting standard requirements. When the LPG tank is mounted to a passenger car, it is generally disposed in a trunk room. Also, in the case of a bus or a commercial vehicle, the LPG tank is secured to the undercarriage of a vehicle body.
Describing a structure of an LPG tank assembly for a vehicle, as shown in
FIG. 5
, an LPG tank is fabricated by welding a copper plate and a thin steel plate with each other to have a thickness on the order of 2.6-3.6 mm. A fuel charging valve
108
, a liquid-phase valve
105
and a gas-phase valve
106
are arranged at a side of the LPG tank assembly
101
. Also, a fuel gauge
107
and other attachments
109
are provided to the LPG tank assembly
101
.
However, the conventional LPG tank assembly constructed as mentioned above suffers from defects in that, because the LPG tank assembly includes only one LPG tank, it is difficult to secure a sufficient amount of LPG which can enable the vehicle to run over a predetermined distance. Furthermore, in the case that the LPG tank assembly is installed in a limited space such as a trunk room, space utilization efficiency in a vehicle is deteriorated, and, in the case that the LPG tank assembly is installed on the undercarriage of the vehicle body, there exists a possibility that a problem is induced in association with a height of the vehicle body from the ground.
SUMMARY OF THE INVENTION
Accordingly, the present invention has been made in an effort to solve the problems occurring in the related art, and an object of the present invention is to provide a liquefied petroleum gas tank assembly for a vehicle, which improves mountability of LPG tanks to a vehicle body and at the same time, allows a sufficient amount of LPG to be secured.
In order to achieve the above object, according to the present invention, there is provided a liquefied petroleum gas (LPG) tank assembly for a vehicle, wherein two or three LPG tanks are communicated one with another through liquid-phase and gas-phase communication pipes and are secured one to another by connection brackets, and mounting brackets are fastened at one ends thereof to one ends of the LPG tanks, respectively, and at the other ends thereof to a body of the vehicle, thereby to prevent the connection brackets and the communication pipes from being damaged or broken due to vibration or impact which is generated in or exerted to the vehicle.
