Description

Technical Field

[0001] This utility model relates to the field of engine connecting rod technology, and in particular to an engine connecting rod assembly. Background Technology

[0002] The connecting rod is one of the key components of a car engine. Its function is to convert the reciprocating motion of the piston into the rotational motion of the crankshaft and to transmit the gas pressure acting on the piston assembly to the crankshaft.

[0003] For example, CN220415987U discloses a connecting rod assembly for an engine, including a connecting rod body, a connecting rod cap, a connecting bolt, and two locating pins. Both the connecting rod body and the connecting rod cap have two mating walls. The mating walls have locating grooves for inserting the ends of the locating pins. The mating walls also have shaft holes for inserting the connecting bolts. The connecting rod body and the connecting rod cap are connected by the connecting bolts. This connecting rod assembly also includes a reinforcing pin. One of the mating walls of the connecting rod body and one of the mating walls of the connecting rod cap have reinforcing grooves. The two ends of the reinforcing pin are respectively embedded in the two reinforcing grooves. The reinforcing groove and the locating groove on the same mating wall are located on both sides of the shaft hole.

[0004] However, in the existing technology, after a long period of use, the lubrication of the connecting parts of the engine connecting rod assembly will decrease due to wear and the entry of debris. If it continues to be used, it will cause wear on the connecting parts of the connecting rod and other structures. The presence of wear will further reduce the lubrication of the connecting parts, which will directly affect the overall transmission efficiency. Utility Model Content

[0005] This utility model mainly provides an engine connecting rod assembly that facilitates improved processing efficiency and prevents deviations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an engine connecting rod assembly, including a connecting rod body, a connecting rod cover spliced ​​to one end of the larger end of the connecting rod body, a protective sleeve provided on the inner side wall of the connecting rod cover and the inner side wall of the larger end of the connecting rod body, a pressing rod snapped onto one side of the connecting rod body, a semi-circular arc plate fixedly connected to one end of the pressing rod, and one side of the semi-circular arc plate overlapping one side of the protective sleeve.

[0007] Preferably, a semi-open frame is fastened to the outer wall of both of the pressing rods.

[0008] Preferably, a connecting rod is fixedly connected between the two semi-open frames.

[0009] Preferably, a second screw is threadedly connected between the semi-open frame and the pressing rod.

[0010] Preferably, a first screw is threadedly connected between the connecting rod cap and the large end of the connecting rod body.

[0011] Preferably, arc-shaped surfaces are provided at the corners on both sides of the main body of the connecting rod.

[0012] Preferably, limiting protrusions are fixedly installed at the junctions of the two pressing rods and the connecting rod body.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, a protective sleeve is provided on the inner wall of the connecting rod cover to protect the connecting parts. This protective sleeve not only slows down the wear rate of the connecting rod body but also prevents impurities from entering the connecting parts, thus protecting them. During use, the position of the protective sleeve is determined by two semi-circular arc plates to ensure its stability. When replacement is needed, the two semi-circular arc plates can be released to release the protective sleeve for convenient and quick replacement.

[0015] 2. In this utility model, the pressing rod is embedded in the connecting rod body by a limiting protrusion, which can ensure the stability of the pressing rod. Furthermore, a semi-open frame to enhance stability is set on the pressing rod, and a connecting rod is connected between the two semi-open frames to reduce the difficulty of disassembling the pressing rod.
