Description

Technical Field

[0001] The utility model relates to a novel ultra-thick high-pressure cast aluminum alloy flywheel housing, belonging to the technical field of die casting. Background Art

[0002] The engine and the gearbox are integrated into a whole to form the entire powertrain through the flywheel housing, and the starter is assembled on the flywheel housing. The flywheel housing is connected to the diesel engine body through the gear chamber. The flywheel housing connects the engine body and the gearbox, protects the flywheel and the clutch, and carries the load.

[0003] The traditional process for flywheel housing projects is gravity casting, which has disadvantages such as heavy product weight, low production efficiency, and poor dimensional accuracy. These disadvantages can be effectively improved through aluminum alloy high-pressure casting. Utility Model Content

[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a novel ultra-thick high-pressure cast aluminum alloy flywheel housing, thereby solving the above-mentioned technical problems.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a new type of ultra-thick high-pressure cast aluminum alloy flywheel housing, including a flywheel housing shell; a plurality of weight-reducing grooves are arranged on the flywheel housing shell; the weight-reducing grooves are located at the main shell wall thickness position of the flywheel housing shell; and a cross-arranged reinforcing rib is arranged at the position where the weight-reducing groove is located.

[0006] Furthermore, the inner wall thickness of the flywheel housing is 5 mm.

[0007] Furthermore, a plurality of inclined and crossed reinforcing ribs are arranged on the suspension support points of the flywheel housing.

[0008] Furthermore, a plurality of reinforcing ribs are provided on the shell surface of the flywheel housing.

[0009] The beneficial effects of the utility model are as follows: the utility model adopts aluminum alloy, and compared with the cast iron flywheel shell, the weight of the utility model is reduced by 60%. Under the premise of ensuring the key performance indicators such as the reliability of the aluminum alloy flywheel shell, it can achieve lightweight, reduce the weight of the engine, reduce pollutant emissions, and improve the appearance quality and competitiveness of the engine. For automobiles, it can reduce the fuel consumption and emissions of the whole vehicle to a certain extent, improve product quality and competitiveness, and at the same time help reduce the fuel consumption and emissions of the whole vehicle.
