Abstract

The invention belongs to the technical field of vehicles, and discloses a connecting rod structure and an engine. The connecting rod structure comprises a connecting rod body and a connecting rod cover. The connecting rod body and the connecting rod cover are detachably connected through a connecting rod bolt. A connecting rod large head hole is formed between the connecting rod body and the connecting rod cover. A cutting contact surface between the connecting rod body and the connecting rod cover is not overlapped with the central plane of the connecting rod large head hole and is located onone side, close to the connecting rod cover, of the central plane. According to the connecting rod structure, if the length of the connecting rod bolt is unchanged, the contact length of the connecting rod bolt and the connecting rod body is increased so as to enhance the connecting strength between the connecting rod cover and the connecting rod body; and if the contact length of the connectingrod bolt and the connecting rod body is kept unchanged, the thickness between the bottom of a connecting rod bolt hole and the side wall of the connecting rod body is increased, and the situation thatthe wall thickness between the connecting rod bolt hole and the connecting rod body is too small, and bending deformation happens easily is avoided, so that the rigidity of a connecting rod large head is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a connecting rod structure and an engine. Background technique [0002] Existing connecting rod comprises connecting rod small end, connecting rod large end and connecting rod body, and connecting rod small end is the part that is connected with piston pin, and connecting rod large end is the part that is connected with crankshaft, and connecting rod body is connecting rod small end, connecting rod. The portion of the shaft between the large ends of the shaft. Since the connecting rod is respectively connected to the piston and the crankshaft, the connecting rod can bear the gas force from the piston pin and transmit it to the crankshaft to convert the reciprocating motion of the piston into the rotary motion of the crankshaft. [0003] The existing connecting rods are divided into flat cut connecting rods (such as figure 1 shown) and miter cut link (as figure 2 shown) two t...
