| 摘要 |
The present invention relates to an apparatus for controlling the ascending/descending operations of an auxiliary wheel of a truck, in which an inlet hose and an outlet hose, acting as passages for air pressure serve as means for lifting/lowering the auxiliary wheel, a switch cable, and a gauge hose, are arranged in a main body of the apparatus, and a cover is hinged to the front surface of the main body. Thus, each of the hoses and the switch cable are prevented from being outwardly exposed, thereby preventing the apparatus from deteriorating or being damaged by external foreign substances and moisture, and preventing the hoses of each line from being frozen in the winter. In addition, a bracket is coupled and fixed onto a rear surface of the main body to enable the apparatus to be easily mounted on a lower frame of a cargo container of the truck. The apparatus of the present invention comprises: main body (10), one side of which has locking protrusion (11), a hollow interior, and an open front surface; cover (20), one side of which has locking piece (21) corresponding to locking protrusion (11) formed at said one side of the main body, and which is coupled to a side surface of main body (10) via hinge (22); bracket (30) coupled to a rear surface of main body (10) for arranging main body (10) on the lower frame of the truck; support plate (40) to be introduced into the hollow interior of main body (10); distribution controller (41), pressure gauge (42), and switch (43) mounted on a front surface of support plate (40); inlet hose (50) introduced into main body (10) from the rear surface thereof and connected to distribution controller (41); outlet hose (60) connected to distribution controller (41) and drawn from the interior of main body (10) to the outside of the rear surface thereof; switch cable (70) introduced from the rear surface of main body (10) into the interior thereof and electrically connected to switch (43); and gauge hose (80), which connects distribution controller (41) to pressure gauge (42), and which is arranged on a rear surface of support plate (40) introduced into the interior of main body (10). |
