Abstract
The utility model relates to a connecting rod of a 2.8L TCI diesel engine, which comprises a connecting rod big end, a connecting rod small end, a rod body, a connecting rod bolt and a bolt hole of the connecting rod. The rod body and the connecting rod small end use a big guiding angle as transition. The longitudinal chamfer angle is 70 mm, and the transverse chamfer angle is 9 mm. The utility model lightens the weight of the connecting rod and simultaneously ensures rigidity and strength of the connecting rod.
Description
Technical field
The utility model relates to a kind of engine components, relates to a kind of connecting rod of diesel engine specifically.
Background technique
Connecting rod is one of strength member of motor, and its effect is that the power that piston bears is passed to bent axle, thereby makes the to-and-fro motion of piston change rotatablely moving of bent axle into.It is very abominable in the working condition of engine interior.Connecting rod bears gas load and itself swing and the reciprocating inertial force of piston set that wrist pin transmits.The size and Orientation of these power all is periodically variable.What therefore, connecting rod was subjected to is alternate loads such as compression, stretching and bending.This just requires connecting rod under the as far as possible little condition of weight, and enough rigidity and intensity are arranged.But prior art is difficult to alleviate simultaneously the weight of connecting rod again under the prerequisite that has guaranteed rigidity and intensity, when having alleviated connecting rod weight, be difficult to guarantee the rigidity and the intensity of connecting rod again.
Summary of the invention
At the deficiencies in the prior art, the utility model is designed when having alleviated connecting rod weight, can guarantee the connecting rod of the rigidity and the intensity of connecting rod simultaneously again.
The utility model is achieved through the following technical solutions:
A kind of connecting rod of 2.8 liters of TCI diesel engine comprises connnecting rod big end, connecting rod small end, shaft, connecting-rod bolts and connecting-rod bolts hole, adopts big lead angle transition between its shaft and the connecting rod small end.
A kind of connecting rod of 2.8 liters of TCI diesel engine, the vertical chamfering between its connecting rod shank and the connecting rod small end is 50～100mm, laterally chamfering is 5～15mm.
A kind of connecting rod of 2.8 liters of TCI diesel engine, the vertical chamfering optimum value between its connecting rod shank and the connecting rod small end is 70mm, laterally the chamfering optimum value is 9mm.
A kind of connecting rod of 2.8 liters of TCI diesel engine, the centre distance of connecting rod are 160～175mm, and the connecting rod small end bore dia is 32～40mm, and the connnecting rod big end bore dia is 52～60mm.
A kind of connecting rod of 2.8 liters of TCI diesel engine, the centre distance optimum value of connecting rod is 168mm, and connecting rod small end bore dia optimum value is 37mm, and connnecting rod big end bore dia optimum value is 56mm.
A kind of connecting rod of 2.8 liters of TCI diesel engine, the spacing between its connecting-rod bolts hole are 64～72mm bolt hole lateral deviation 0.5～2.5mm backward.
A kind of connecting rod of 2.8 liters of TCI diesel engine, the spacing optimum value between its connecting-rod bolts hole is 68mm, bolt hole lateral deviation optimum value backward is 1.5mm.
Adopt big lead angle transition between shaft and the connecting rod small end, in the hope of obtaining the weight that reduces connecting rod shank under the enough prerequisites of strength and stiffness.Spacing between connnecting rod big end diameter, connecting rod small end diameter, the connecting-rod bolts hole and bolt hole backward numerical value such as lateral deviation value design and determine that all for when alleviating connecting rod weight, the while can guarantee the rigidity and the intensity of connecting rod.
