What Is The Function of Flywheel Housing

The function of the flywheel housing is to bear the weight, position the engine and transmission, and place the starting parts.

The flywheel housing is an important component installed between the automobile engine and transmission. It connects the crankcase, starter and engine oil pan, and also contains the flywheel assembly internally. The main function of the flywheel shell is to serve as access to the body, protection and carrier. It usually consists of a shell, a support plate and bolts, with screw holes on both sides of the shell and bolt holes on the support plate. The bolts pass through the bolt holes on the support plate and are screwed into the screw holes on the housing to connect the support plate to the housing. The number and position of the threaded holes on the support plate are confirmed according to the assembly requirements of the automobile engine. The practicality of this new type of flywheel housing lies in the fact that it can adapt to different assembly requirements by replacing the supporting plate. The housing can be used universally, which reduces molds and tooling, improves mass production efficiency, reduces the types of parts, and reduces the cost of production, management, and Financial and warehousing management costs, thereby reducing cost expenses.

In addition, the flywheel housing also has the function of dissipating heat and removing metal powder. It has a simple structure and is easy to install. It accommodates the clutch assembly, bears the weight of the transmission, and serves as a fulcrum for power transmission. Although the flywheel housing does not have much wear and tear, its damage, deformation and misalignment will have a great impact on the engine. Since the flywheel shell bears weight and external forces, cracks and deformation will inevitably occur. After the flywheel housing is deformed, its parallelism and the centrality of the bearing hole lose their original accuracy. That is, the bearing hole of the flywheel housing cannot be concentric with the center of the crankshaft and the center of the transmission, causing the centers of the engine and transmission to deviate. This will affect the transmission of power, increase the wear of the driven part, and produce abnormal transmission noise.
