Embodiment Construction
[0013] The present invention will be further described below in conjunction with accompanying drawing:
[0014] see figure 1 , This structure is mainly composed of the car body passenger compartment 1, the transmission cover 2, the first and second sealing strips 6,7, and the first and second seams 4,5.
[0015] see image 3 , the passenger compartment 1 has an opening at a position corresponding to the transmission, and a step 11 is formed at the opening, the step surface is a mounting surface fixedly connected with the transmission cover 2, and the edge of the step has a first notch 5 perpendicular to the mounting surface.
[0016] see Figure 4 , the transmission cover 2 is covered at the opening of the passenger compartment 1, and the mouth of the transmission cover 2 has an L-shaped outer flange 21, which is used as a mounting surface fixedly connected with the passenger compartment 1, and the inside of the transmission cover 2 is about higher than the passenger compart...

The invention relates to a composite sealing structure of a passenger compartment and a transmission cover. The composite sealing structure comprises the vehicle body passenger compartment, the transmission cover and sealing strips and is characterized in that the positon, corresponding to a transmission, of the passenger compartment is provided with an opening, a step is formed at the opening, the step face is a mounting face fixedly connected with the transmission cover, the edge of the step is provided with a first spigot, the transmission cover covers the opening of the passenger compartment, the opening of the transmission cover is provided with an L-shaped flanging serving as the mounting face fixedly connected with the passenger compartment, and a position, slightly higher than thefirst spigot, of the inner side of the opening of the transmission cover is provided with a second spigot vertical to the transmission cover; the passenger compartment is fixedly connected with the transmission cover, the first sealing strip is clamped between the mounting faces of the passenger compartment and the transmission cover, and the second sealing strips are mounted at the first spigot of the passenger compartment and the second spigot of the transmission cover. The composite sealing structure has the advantages that the second spigot, the first spigot and the mounting combining faceof the passage compartment and the transmission are provided with sealing strips, and the sealing structure is compact, simple to mount, safe, reliable, especially suitable for sealing during armoredvehicle wading and capable of satisfying overall vehicle use requirements.
Description
technical field [0001] The invention relates to an automobile body sealing technology, in particular to a composite sealing structure of a wheeled armored vehicle passenger compartment and a transmission cover. Background technique [0002] The body of the load-bearing armored vehicle is welded and formed by bulletproof steel plates, and is generally divided into a power cabin and a passenger cabin. In order to overhaul the power components of the chassis (such as engine, transmission, etc.) and improve the maintainability of the vehicle, it is usually necessary to add an inspection cover (cover) inside the passenger compartment, which involves the sealing problem between the inspection cover (cover) and the car body . Good sealing can prevent water and dust, cut off noise, improve human-machine efficiency, and improve the comfort of the car environment. The traditional sealing method between the maintenance cover and the car body is a structural form of flat rubber pad an...
