This process not only enables the front half shield 202 and the rear half shield 203 to be quickly and preliminarily connected to the chassis 1, but also facilitates the subsequent disassembly and installation of the shield, thereby providing convenience for the maintenance of the emergency brake parking control device. After the clamping is completed, the right sides of the two front half shields 202 are respectively tightly attached to the left sides of the corresponding rear half shields 203, and a relatively closed protection space is preliminarily constructed. At this time, the connection plate one 205 fixedly connected to the bottom front and rear sides of the front half shield 202 and the connection plate two 206 fixedly connected to the bottom front and rear sides of the rear half shield 203 begin to play a further reinforcing role.
