Abstract

The utility model relates to an automobile engine chain which not only can be used to replace a belt and a gear but also has a long service life. The automobile engine chain comprises outer chain links, inner chain links, sleeves and rollers, wherein the outer chain links are in mutually embedded connection with the inner chain links in an internally and externally staggered manner; the sleeves and the rollers are sleeved on chain pin shafts; the outer chain links and the inner chain links are respectively provided with outer chain plates and inner chain plates; the diameters of the circular arcs at two end parts of each outer chain plate and the diameters of the circular arcs at two end parts of each inner chain link are 7.6 max; the inner distance between the two outer chain plates of each outer chain link is 7.45 min; each outer chain plate as well as each inner chain plate is provided with two chain pin shaft holes, and the distance between the two chain pin shaft holes is 8; each chain pin shaft is 11.4 max in length; the outer distance between the two inner chain plates of each inner chain link is 7.4 max; the inner distance between the two inner chain plates of each inner chain link is 4.6 min; and the ultimate tensile load of an automobile timing chain is not less than 7.8 kN. The utility model has the advantages that the design of the automobile timing chain with a long service life not only fills in the gap in the field of China, but also reduces the importation of feeding chains and further greatly saves cost and payout.

Description

Rule chain during automobile

Technical field

The utility model relates to a kind ofly can either substitute belt and gear, has the motor car engine chain of long service life again, belongs to auto parts and components and makes the field.

Background technique

CN101451451A, title " timing chain of motor ", comprise chain sheet that is connected into chain and the pin that is connected each chain sheet, every section chain is combined by chain sheet arranged side by side, the mutual embedding that interlocks of the chain sheet of the adjacent chain of each section, connect with pin, the inboard of chain sheet is shaped on the involute sprocket, chain is embedded in the rubber tape, make an integral body with rubber tape, the flank of tooth of sprocket is equal with the inboard toothed surface of rubber tape, the outer fix of chain is embedded with tyre cord in rubber tape, and the rubber tape material adopts nitrile rubber or fluorine rubber.Its deficiency: working life is short.

Summary of the invention

Purpose of design: avoid the deficiency in the background technique, design and a kind ofly can either substitute belt and gear, have the motor car engine chain of long service life again.

Design proposal: in order to realize above-mentioned purpose of design.The utility model is advised the long lifetime of chain when having realized automobile by the further improvement of it being advanced to advise the structure of chain on the basis of the timing chain of available engine.

Technological scheme: rule chain during automobile, it comprises that inside and outside staggered mutual embedding becomes outer link, the inner link of chain, is enclosed within sleeve and roller on the chain hinge pin, and outer link and inner link are respectively equipped with outer, inner plate, and the arc diameters outer, the inner plate two end part of described outer link and inner link are 7.6max; Interior distance between two outer plates of described outer link is 7.45min; Be respectively equipped with two chain pin axis holes and pitch-row on the carrier bar of described outer link and inner link and be respectively 8; The axial length of described chain hinge pin is 11.4 max; External distance between two inner plates of described inner link is 7.4max; Interior distance between two inner plates of described inner link is 4.6min; The limit tensile load of rule chain is not less than 7.8KN during described automobile.The two end portions Magnification that described chain hinge pin stretches out the outer link carrier bar is not less than 3% and to increase the back diameter be 3.15min respectively; Its extension length is 0.85min; Inclined-plane and horizontal plane angle that its augmenting portion periphery is on angular type and the end face are 30 degree.The outer plate of described chain hinge pin and outer link, its torque value of the inner plate of described sleeve and inner link is not less than 0.8N.m respectively.

The utility model is compared with background technique, and the one, long lifetime automobile time rule chain design has not only been filled up the blank of China in this field, and has been reduced advancing to advise the import of chain, has saved the cost expenditure widely; The 2nd, projected life is consistent with car load, need not periodic replacement, has increased the unfailing performance of car load; The 3rd, compact structure, transmitted power height, reliability and wear resistance height; The 4th, durable in use, non-maintaining throughout one's life, rupture in advance and make the user need bear the maintenance expenses of costliness because of ignoring periodic replacement belt or belt thereby reduced the car load user because of suffering failure of engine components.
