Abstract
The utility model discloses a driving cab sealing structure of a heavy truck, which comprises a first sealing strip and a second sealing strip. The first sealing strip and the second sealing strip are arranged on an outer plate of a side wall. Since both the two sealing strips are arranged on the side wall, variation of a sealing gap due to deformation of a driving cab is compensated, and sealing performance of the driving cab is guaranteed.
Description
Technical field
The utility model relates to automobile technical field, particularly relates to a kind of cab of heavy truck hermetically-sealed construction.
Background technology
The leak tightness of general cab of heavy truck depends on the leak tightness of car door to a great extent.The door seal structures of domestic heavy card mostly is the individual layer sealing, minority is one deck semitight, be to have only sealing band or semitight bar together together between car door and the gusset, its sealing band of individual layer hermetically-sealed construction is installed on the side-wall outer-plate, one deck semitight structure all is that a whole circle sealing band is installed on the car door, in addition half road sealing band is installed on the side-wall outer-plate, is used for rainproof, dustproof and sound insulation.
Because the sealing effectiveness of sealing band depends on the gap between car door and the gusset sheet metal component.The seal clearance of new car generally can both be adjusted to design value as required, though prior art can play sealing function, but along with vehicle uses for a long time, distortion to a certain degree can take place in operator's compartment, cause seal clearance to change, surpass certain limit when seal clearance changes, the prior art scheme just is difficult to guarantee the sealing property of operator's compartment, with phenomenon such as occurring leaking, dust is invaded and room noise is big, influence travelling comfort.
The utility model content
(1) technical matters that will solve
The technical problems to be solved in the utility model is the leak tightness that how to guarantee cab of heavy truck.
(2) technical scheme
For solving the problems of the technologies described above, a kind of cab of heavy truck hermetically-sealed construction is provided, comprise first sealing band and second sealing band that are arranged on the side-wall outer-plate.
Preferably, when described first sealing band is configured such that proper closing of the door, form sealing between inner plate of car door and the side-wall outer-plate.
Preferably, described first sealing band is fixed in the doorframe border of described side-wall outer-plate by bail.
Preferably, described first sealing band is fixed in the doorframe border of described side-wall outer-plate by glue bond.
Preferably, described second sealing band is with respect to the inner doorframe border that is arranged at described side-wall outer-plate of described first sealing band.
Preferably, described second sealing band has the U-shaped portion that fixes with the doorframe border of side-wall outer-plate.
(3) beneficial effect
By the two seals bar all is arranged on the gusset, remedied because the seal clearance that the operator's compartment distortion causes changes, guaranteed the sealing property of operator's compartment.
Description of drawings
Fig. 1 is the structural representation of the cab of heavy truck hermetically-sealed construction of the utility model embodiment;
Fig. 2 is the structure section figure of the cab of heavy truck hermetically-sealed construction of the utility model embodiment.
Wherein, 1: side-wall outer-plate; 2: the first sealing bands; 3: the second sealing bands; 4: inner plate of car door.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As depicted in figs. 1 and 2, the utility model provides a kind of cab of heavy truck hermetically-sealed construction, comprises first sealing band 2 and second sealing band 3 that are arranged on the side-wall outer-plate 1.When described first sealing band 2 is configured such that proper closing of the door, form sealing between inner plate of car door 4 and the side-wall outer-plate 1.First sealing band 2 can be fixed in the doorframe border of side-wall outer-plate 1 by bail or glue bond.Second sealing band 3 is with respect to first sealing band, the 2 inner doorframe borders that are arranged at side-wall outer-plate 1.Second sealing band 3 also can be fixed in the doorframe border of side-wall outer-plate 1 by bail or glue bond, and perhaps, second sealing band 3 has the U-shaped portion that fixes with the doorframe border of side-wall outer-plate 1.
As can be seen from the above embodiments, the utility model embodiment has improved the sealing property of operator's compartment greatly, thereby has improved travelling comfort by the whole circle of twice sealing band all is fixed on the side-wall outer-plate.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
