Description

Technical Field

[0001] The utility model specifically relates to the technical field of engine end covers, in particular to a lightweight and high-rigidity engine end cover. Background Art

[0002] The engine is a machine that ignites the fuel mixture in the cylinder and converts the heat energy generated by its combustion into mechanical energy, and then transmits the power to the rear wheels of the vehicle through the transmission mechanism through the crankshaft to become the driving force of the vehicle. As the power source of the vehicle, the engine plays an important role;

[0003] With the occurrence of accidents, the weight of vehicles is becoming lighter and lighter, so the weight of the engine is also being reduced. The traditional engine end cannot dissipate the large amount of heat generated by the engine during operation, which will cause the engine to burn red, which will directly affect the service life of the engine.

[0004] After searching, Chinese patent publication number CN202022593432.1 discloses a high-strength automobile engine end cover; including an engine housing, a fixed shell is provided on one side of the engine housing, a first fixing ear is provided on the outer side of the fixed shell, a through hole is opened in the middle of the fixed shell, and a plurality of reinforcing sheets are equidistantly provided on the outer side of the through hole, a front cover is clamped on one side of the fixed shell, a second fixing ear is provided on the outer side of the front cover, a through hole is opened on one side of the front cover, and a fixing ring is installed and fixed in the through hole;

[0005] In the above patent, a fixed shell is sleeved between the end cover and the engine casing, and then the external thread on the engine casing is effectively connected with the internal thread of the fixed shell, and then the end cover is fixedly installed on the fixed shell. In this way, during the long-term use of the vehicle, the external thread on the engine casing and the internal thread of the fixed shell will become loose, which will directly affect the quality of engine use; the end cover connection method in the above patent can only be used on flat roads. When the vehicle is driving on a rugged road, the engine casing and the fixed shell will separate in a short time, so that the engine cannot provide power to the vehicle normally, making the vehicle unable to move.

[0006] Therefore, we provide a lightweight, high-rigidity engine end cover. In this device, the end cover body is fixedly installed on the engine casing through the mounting hole. Such mounting efficiency can effectively ensure the firmness of the connection. A through hole of the rotating shaft is also provided on the end cover body to facilitate the output shaft of the engine to transmit power to the outside. In this way, when the engine is driven, the power of the engine can be transmitted to the outside to drive the vehicle; when the engine transmits power to the outside, the belt installed inside the cover drives the rotation of the wheel to drive the rotating shaft in the through hole, so that the power inside the engine is transmitted to one side of the end cover body.
