Further, the thickness of described interlayer is 0.9 μm.
Further, the thickness of described enhancement Layer is 3.0 μm.
The beneficial effects of the utility model: motorcycle gear-shifting device of the present utility model, by arranging wearing layer group on the surface of rocking arm, front running board and back step, effectively can strengthen its friction resistant ability, effectively reducing wear condition, extend its service life, reduce use cost; In wearing layer group, basal layer can stop mirror shell surface metal to penetrate in interlayer and enhancement Layer, and interlayer can make enhancement Layer effectively deposit, enhancement Layer is wear-resisting, withstanding corrosion, difficult drop-off, environmental protection, abrasion resistance is good; The thickness range of basal layer, interlayer and enhancement Layer is all determined by experiment, can realize wear-resisting while conservation, improve work efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model wearing layer group.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, Fig. 2 is the structural representation of the utility model wearing layer group, as shown in the figure: the motorcycle gear-shifting device of the present embodiment, the pull bar 9 comprising rocking arm 1, be connected to the front running board 2 at rocking arm 1 two ends and back step 3 and be removably connected with rocking arm 1, described rocking arm 1, front running board 2 and back step 3 are made by metallic material, described front running board 2 is provided with front Non-slip material 4, and described back step 3 is provided with rear Non-slip material 5; The surface of described rocking arm 1, front running board 2 and back step 3 is provided with wearing layer group, described wearing layer group forms by from interior basal layer 61, interlayer 62 and the enhancement Layer 63 set gradually outward, described basal layer 61 is the carbide layers of thickness 1.5 μm-3.0 μm, described interlayer 62 is the nickel dam of thickness 0.6 μm-1.2 μm, and described enhancement Layer 63 is the boron nitride layer of thickness 2.0 μm-4.0 μm; Basal layer, interlayer and enhancement Layer can adopt physical vapor deposition (PVD) (PVD) method, chemical vapor deposition (CVD) method and their combination and variation method to apply as the case may be; By arranging wearing layer group on the surface of rocking arm 1, front running board 2 and back step 3, effectively can strengthen its friction resistant ability, effectively reducing wear condition, extending its service life, reduce use cost; In wearing layer group, basal layer 61 can stop mirror shell surface metal to penetrate in interlayer 62 and enhancement Layer 63, and interlayer 62 can make enhancement Layer 63 effectively deposit, enhancement Layer 63 is wear-resisting, withstanding corrosion, difficult drop-off, environmental protection, abrasion resistance is good; The thickness range of basal layer 61, interlayer 62 and enhancement Layer 63 is all determined by experiment, can realize wear-resisting while conservation, improve work efficiency; Preferably, the thickness of described basal layer 61 is 2.5 μm, and the thickness of described interlayer 62 is 0.9 μm, and the thickness of described enhancement Layer 63 is 3.0 μm, and experiment shows, this one-tenth-value thickness 1/10 can realize the optimization of machining status.
