Abstract
The utility model discloses a shift rocker arm assembly. The shift rocker arm assembly comprises a shift rocker arm (1), a rocker arm base (2), an inhaul cable pin (3) and a balancing weight (4), wherein the upper portion of the rocker arm base (2) is sleeved with the middle portion of the shift rocker arm (1), the upper portion of the rocker arm base (2) and the middle portion of the shift rocker arm (1) are fixed in a welding mode, the balancing weight (4) is fixed at the left end of the shift rocker arm (1) in a welding mode, the inhaul cable pin (3) is installed in an installing hole in the right end of the shift rocker arm (1), a step (5) is arranged between the balancing weight (4) and the shift rocker arm (1), and a gap is reserved between the balancing weight (4) and the shift rocker arm (1). The shift rocker arm assembly is ingenious in concept, simple in structure and low in cost. The step is ingeniously and additionally arranged on the balancing weight, the gap is reserved between the shift rocker arm and the balancing weight after welding, the contact area is greatly reduced, the acid water can outflow conveniently, and therefore the occurrence that the acid water corrodes a zinc layer is avoided.
Description
Technical field
The utility model relates to a kind of member on the automotive transmission, specifically, and particularly a kind of gear-shifting rocker arm assembly.
Background technique
As shown in Figure 1, 2, existing gear-shifting rocker arm assembly comprises gear-shifting rocker arm 1, rocker arm bracket 2, dragline pin 3 and balancing weight 4, wherein the middle part of gear-shifting rocker arm 1 is set in the top of rocker arm bracket 2, and by being welded and fixed, by being welded with described balancing weight 4, described dragline pin 3 is housed in the mounting hole of gear-shifting rocker arm 1 right-hand member at the left end of gear-shifting rocker arm 1.
Because gear-shifting rocker arm 1 and balancing weight 4 contact by face, the gapless area of contact is large; In the pickling stage of zinc-plated pretreatment, sour water is contained between the surface of contact and can't flows out, adopt now pressurized air and vibrations all can't thoroughly solve, ooze in transportation and storage stage sour water behind the zinc-plated finished product, the corrosion zinc layer affects outward appearance, need to repeat zinc-plated, increased cost, quality of product can not get good assurance.
The model utility content
Technical problem to be solved in the utility model is to provide the very easily gear-shifting rocker arm assembly from flowing out between gear-shifting rocker arm and the balancing weight of a kind of pickling stage sour water.
The technical solution of the utility model is as follows: a kind of gear-shifting rocker arm assembly, comprise gear-shifting rocker arm (1); rocker arm bracket (2); dragline pin (3) and balancing weight (4); wherein the middle part of gear-shifting rocker arm (1) is set in the top of rocker arm bracket (2); and by being welded and fixed; at the left end of gear-shifting rocker arm (1) by being welded with described balancing weight (4); in the mounting hole of gear-shifting rocker arm (1) right-hand member described dragline pin (3) is housed; be provided with step (5) between described balancing weight (4) and the gear-shifting rocker arm (1), and leaves the gap between balancing weight (4) and the gear-shifting rocker arm (1).
The utility model adopts above structure, by increased a step at balancing weight, leaves the gap between gear-shifting rocker arm and the balancing weight after the welding cleverly, and area of contact reduces greatly, is conducive to the outflow of sour water, thereby has avoided sour water corrosion zinc layer.
In order not affect the use structure of gear-shifting rocker arm assembly, avoid as much as possible again the zinc layer on the sour water corrosion gear Rocker arm assembly, described step (5) is cylindrical structure, and the bottom surface diameter of described step (5) is 20-30mm, and the thickness of described step (5) is 0.5-1mm.
In order to guarantee that the gear-shifting rocker arm assembly does not produce shake, described step (5) is same axle center with balancing weight (4).
Beneficial effect: the utility model is skillfully constructed, simple in structure, cost is low, by increased a step at balancing weight, leave the gap between gear-shifting rocker arm and the balancing weight after the welding cleverly, area of contact reduces greatly, be conducive to the outflow of sour water, thereby avoided sour water corrosion zinc layer.
