Abstract
The utility model relates to a rocker structure for auto engine, which is characterized in that: a rocker (1) formed by solid forging is provided with a heave (2) on lower end at head, which is provided with a heave section (3) contacting with outline of a cam on upper end surface and a vertical screw at tail. By adopting the overall structure, the utility model has the advantages of high reliability and low cost.
Description
Technical field
The utility model relates to motor car engine accessory field, is specifically related to a kind of motor car engine rocker structure.
Background technique
At present, the automobile rocking arm is to be welded with inserting by forging.Owing to insert and be powdered metallurgical material, with forging when inserting welding, the technical requirements height.Because what rocking arm bore in the course of the work is the effect of high speed time dependent loading, forging after installation, often occur inserting with the automobile rocking arm that is welded inserted come off, rupture, wear no resistance, the low phenomenon of fatigue strength, bring potential safety hazard to motor.And adopt the forging and the automobile rocking arm cost height of welding of inserting.
Summary of the invention
The purpose of this utility model is, a kind of motor car engine rocker structure is provided.Described rocking arm adopts overall structure, the reliability height is arranged, the advantage that cost is low.
The purpose of this utility model is achieved like this: the head lower end of the rocking arm of a solid forging moulding has projection, has the lug boss that contacts with cam profile on the rocking arm upper-end surface, and the afterbody of rocking arm is provided with a vertical screw.
Owing to adopted such scheme; rocking arm is the solid forging moulding; the head lower end surface of rocking arm has projection; the neutral position of rocking arm upper end has the lug boss that contacts with cam profile, and the afterbody of rocking arm is provided with a vertical screw, because rocking arm adopts the solid forging moulding; the wear resistance that can guarantee rocking arm is good; not only saved purchase ferrous based powder metallurgical and soldering lug material and vacuum high-temperature welding expense, the operation that has also reduced the grinding forging and inserted face of weld, cost of production is reduced.
This rocking arm can be used for the motorcycle engine rocking arm, can reach above-mentioned same effect.
The utility model is described in further detail below in conjunction with drawings and embodiments.
Description of drawings
Fig. 1 is a kind of embodiment of the present utility model.
In the accompanying drawing, 1 is rocking arm, and 2 is projection, and 3 is lug boss, and 4 is bolt, and 5 is nut, and 6 is spring, and 7 is cam, and 8 is valve, and 9 is dead axle.
Embodiment
With reference to Fig. 1, the head lower end surface of the rocking arm 1 of a solid forging moulding is provided with the projection 2 that contacts with valve; the interposition of rocking arm upper end is equipped with the lug boss 3 that contact with cam profile; this lug boss is to extend institute from the rocking arm head to the centre to form; the surface of contact of rocking arm and cam is in the neutral position of this lug boss, and it is integrally formed that described protruding 2, lug boss 3 and rocking arm pass through forging.Ball stud 4 of screw screw-thread fit that the afterbody of rocking arm 1 is vertical, the upper end of ball stud 4 locks with nut 5, the bulb of ball stud 4 cooperates with the shrinkage pool of dead axle 9 side faces, a spring 6 is clamped on ball stud on the dead axle 9; projection 2 of the head lower end surface of rocking arm 1 is connected with the adjusting bolt of valve 8; lug boss 3 that has in the neutral position of rocking arm upper end contacts with cam 7 profiles, and promoting rocking arm under the work of cam, valve is that fulcrum pumps with the ball stud.For the wear resistance that makes rocking arm upper end lug boss, head lower end surface projection good, and fatigue strength height, by carburizing+quenching+low-temperature tempering, perhaps carburizing+quenching+low-temperature tempering+hard chromium plating, any chemical heat treatment method after warm carbon, nitrogen ooze altogether perhaps in three kinds of methods of direct quenching+low-temperature tempering, chemical composition and metallographic structure to this place change, so that rocking arm reaches the requirement of usability in motor.In three kinds of thermo-chemical treatment schemes, in warm carbon, nitrogen co-penetration technology have the characteristics of carburizing and nitriding, better have high compression strength and fatigue strength than the wear-resisting of nitride layer, corrosion resistance is also good than carburized case, manufacture cycle is all than carburizing, nitrogenize weak point, heating-up temperature is lower than carburizing, and the grain growth tendency is little, reduces part deformation, therefore, be a kind of scheme of preferentially selecting for use.
Working procedure of the present utility model is: when cam 7 lift sections contact with rocking arm lug boss 3, rocking arm 1 is applied downward pressure, the rocking arm head end is pressed down open valve; When cam the journey section is fallen when contacting with rocking arm lug boss 3, rocking arm rises under the thrust of valve spring, until valve-closing.The unlatching of motion control valve and so forth, close.
Claims (1)
