It is mainly used to install the pipes and accessories of the brake system and clutch system.
5. Front wall upper assembly
The front wall upper assembly includes left/right hinge base mounting plate big assembly, front wall upper
front cover big assembly, VIN number mounting plate, and front wall upper rear cover big assembly etc.
It forms a high-stiffness frame structure together with the engine compartment assembly and the front wall
lower plate assembly. It can generate strong resistant to the transverse collision and rolling deformation. It can also
separate the engine compartment form the cabin, preventing the odor entering into the cabin. Consequently, it can
isolate the noise, heat and vibration.(2) Floor Assembly The floor assembly is the base work of the main structure. It is a key component that connects various
assemblies and carries the load. The vehicle performance is subject to its strength and stiffness. For the floor
assembly, see the Fig. 5-3.
The floor assembly includes front floor assembly and rear floor assembly. The front floor mid-block goes
through a ridgy channel in longitudinal direction. It can increase the longitudinal rigidity together with the lower
floor longitudinal beam. The space below under the channel is used to install various parts and components, such
as transmission gearshift rod, parking brake cable, discharge pipe with three-way catalytic converter etc. In the
cabin, there is carpet and muffle pad. The floor frame structure is made up of front floor left/right frame, front floor
main plate assembly, front floor mid-bridge assembly, rear frame assembly, rear floor rear block assembly, rear
floor mid-block assembly and longitudinal beam etc. These parts and components provide strong and reliable carry
capacity and ensure that the vehicle meets the strict driving requirement on the body.Fig. 5-3 Floor Assembly
