Abstract
The utility model discloses an automobile connection rod which is provided with a connection rod body, and is characterized in that a titanium layer uniformly covers the connection rod body; the titanium layer on the surface of the connection rod body is obtained by a titanium coating mode; the connection rod body consists of a large end, a small end and a rod body; the large end is connected with the smaller end through the rod body; a large head hole is formed in the large end; a small head hole is formed in the small end; the large end consists of two symmetric semicircular structures; two ends of each of two semicircular structures are connected through a bolt to form the large head hole; the middle of the semicircular structure is connected with the small end through the rod body; the rod body is flat; two reinforcement ribs are respectively arranged on the two sides of the rod body; and an oil hole is formed in the side wall of one end, which is away from the rod body, of the small end. According to the automobile connection rod, the strength of the automobile connection rod is improved, and the high temperature resistance, the abrasion resistance and the corrosion resistance of the automobile connection rod are improved; and the automobile connection rod is more attractive.
Description
Technical field
The utility model relates to a kind of driving component, is specifically related to a kind of automobile connecting bar.
Background technique
Connecting rod is one of main transmission part of motor car engine, usually formed by major part and microcephaly and the body of rod, its major part and bent axle are hinged, the microcephaly is connected with piston by wrist pin, its effect is that the linear reciprocating motion with piston changes rotatablely moving of bent axle into, with outputting power, because connecting rod is in special working environment, need high temperature resistant, wear-resistant, erosion-resisting ability and higher intensity and anti-fatigue performance, general 45 steel that adopt of existing connecting rod material, 40cr, 20MnMo or 40MnB etc., its intensity is not high especially, corrosion-resistant, wear-resistant and high-temperature resistant result is not good especially, especially in refitted car or racing car field, because the rotating speed of refitted car or racing car is high especially, the connecting rod of its motor need have higher intensity, better high temperature resistant, wear-resistant and erosion-resisting ability.
The shortcoming of prior art is: connecting rod strength is not high enough, and high temperature resistant, wear-resistant and erosion-resisting ability is strong inadequately.
The model utility content
The purpose of this utility model is to provide a kind of intensity height, high temperature resistant, wear-resistant, automobile connecting bar that corrosion stability is good.
For achieving the above object, the technical solution of the utility model is as follows: a kind of automobile connecting bar, be provided with con-rod only, and its key is: described con-rod only surface evenly is coated with titanium layer.
The surface coverage of above-mentioned automobile connecting bar has titanium layer, has strengthened high temperature resistant, the wear-resistant and anti-corrosion capacity of con-rod only, and intensity also is improved, because titanium layer is golden, makes con-rod only more attractive in appearance simultaneously, is particularly suitable as refitted car or racing car connecting rod.
Described con-rod only surface evenly is coated with titanium layer.Mode by titanizing obtains titanium layer, and technology is simple, technology maturation.Can adopt titanium anodization technology, gas phase deposition technology or differential arc oxidization technique to obtain titanium layer.
Described con-rod only is made up of big end, small end and the body of rod, connects by the body of rod between described big end and the small end, and described big end is provided with big end hole, and small end is provided with the microcephaly hole.The surface coverage of big end, small end and the body of rod has titanium layer, and microcephaly hole and big end hole inwall can not have titanium layer, and the microcephaly hole of small end is connected with piston by wrist pin in use, and the big end hole of big end is connected with bent axle.
Described big end is made up of the part-annular structure of two symmetries, connects by bolt between the two ends of two part-annular structures, constitutes big end hole, and one of them part-annular structure middle part is connected with small end by the body of rod.The part-annular structure of two symmetries connects by bolt and is the anchor ear shape, makes big end structure simple, is convenient to processing.
The described body of rod is flat, and these body of rod both sides are respectively arranged with two stiffening ribs.Article two, stiffening rib increases the intensity of the body of rod, and weight increases seldom.
Described small end is provided with oilhole away from the sidewall of the body of rod one end.When engine operation, the high speed rotating by bent axle with the lubricating oil splash of cylinder block bottom in the oilhole of small end, with the kinematic pair in the lubricated microcephaly hole.
The beneficial effects of the utility model are: the utility model has improved the intensity of automobile connecting bar, and high temperature resistant, the wear-resistant and anti-corrosion capacity of automobile connecting bar is strengthened, and more attractive in appearance.
