Abstract
The invention discloses a positioning mechanism of an air suction swing arm shaft. The positioning mechanism comprises a camshaft supporting body (1), an air suction swing arm shaft (2) and a positioning pin (3), wherein the camshaft supporting body (1) is provided with a positioning pin hole; the positioning pin hole is provided with the positioning pin (3) internally; the camshaft supporting body (1) is provided with the air suction swing arm shaft (2) through a hole; and the air suction swing arm shaft (2) is provided with the positioning pin hole which is used for realizing axial running and circumferential rotation of the air suction swing arm shaft through the matching of the air suction swing arm shaft and the positioning pin. The positioning mechanism provided by the invention has the advantages of stable and reliable structure, after the mounting of the positioning pin, the abrasion of the air suction swing arm shaft is reduced, and the reliability of the engine is strengthened.
Description
Technical field
The invention belongs to the engine components technical field, be specifically related to a kind of intake rocker axle allocation mechanism.
Background technique
The distribution mode of original structure design is: Single Over Head Camshaft drives rocking arm, and rocking arm drives valve motion.Wherein the intake rocker assembly is fixed on the camshaft support.Motion mode is: cam moves into the rotation of gas pitman arm shaft and drives valve.Pitman arm shaft thrust mode is that an end is processed thrust surface on the camshaft support, and an end adds jump ring on the intake rocker axle, prevents intake rocker axle axial float.
The deficiency of this design proposal is: nothing prevents the function that pitman arm shaft rotates in a circumferential direction in the structural design, and the rotation of intake rocker axle can be accelerated the rocking arm wearing and tearing; Because the manufacturability of processing, assembling is poor, still there is certain axial movement value in the intake rocker axle.Axial float influences cooperating of intake rocker and overhead camshaft, intake valve in the course of the work, and producing noise also influences valve motion.
In sum, prior art can't realize effective location of intake rocker axle, is unfavorable for the realization of engine reliability.
Summary of the invention
The invention provides a kind of intake rocker axle allocation mechanism, solved the big problem of intake rocker axle axial movement value in the prior art.
The present invention can be achieved through the following technical solutions: a kind of intake rocker axle allocation mechanism, comprise camshaft support 1, intake rocker axle 2, locating stud 3, have positioning pin hole on the camshaft support 1, be provided with locating stud 3 in the positioning pin hole, camshaft support 1 is provided with intake rocker axle 2 by the hole, has on the intake rocker axle 2 to be used for the intake rocker axle cooperates realization intake rocker axle with locating stud axial float and the positioning pin hole that rotates in a circumferential direction.
The present invention compared with prior art has following beneficial effect: structural stability of the present invention, reliable, behind the installing and locating pin, reduced the wearing and tearing of intake rocker axle, and strengthened engine reliability.
Description of drawings
Fig. 1 is a structural representation of the present invention,
Fig. 2 is the locating pin structure schematic representation,
Fig. 3 is the sectional drawing of Fig. 1 side view.
Embodiment
Be described in further detail by embodiment below in conjunction with accompanying drawing.
A kind of intake rocker axle allocation mechanism, comprise camshaft support 1, intake rocker axle 2, locating stud 3, have positioning pin hole on the camshaft support 1, be provided with locating stud 3 in the positioning pin hole, camshaft support 1 is provided with intake rocker axle 2 by the hole, has on the intake rocker axle 2 to be used for the intake rocker axle cooperates realization intake rocker axle with locating stud axial float and the positioning pin hole that rotates in a circumferential direction.
Assembly process is as follows: with the locating stud part camshaft support 1 of packing into, the intake rocker axle is inserted in camshaft support 1 hole, adjust intake rocker axle 2, with the locating stud camshaft support 1 of packing into fully.So just realized that locating stud is fixed on the camshaft support 1.By cooperating the axial float (as shown in Figure 1) of realizing intake rocker axle 2 and the control of rotate in a circumferential direction (as shown in Figure 3) between intake rocker axle 2 and the locating stud 3.
Claims (1)
1. intake rocker axle allocation mechanism, comprise camshaft support (1), intake rocker axle (2), locating stud (3), it is characterized in that: the camshaft support has positioning pin hole on (1), be provided with locating stud (3) in the positioning pin hole, camshaft support (1) is provided with intake rocker axle (2) by the hole, has on the intake rocker axle (2) to be used for the intake rocker axle cooperates realization intake rocker axle with locating stud axial float and the positioning pin hole that rotates in a circumferential direction.
