Fig. 1 is the diagrammatic cross-section that speed of a motor vehicle counter that the utility model provides constructs a kind of embodiment;
Fig. 2 is the close-up schematic view of a-quadrant shown in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1, is the section assembling schematic diagram that speed of a motor vehicle counter that the utility model provides constructs a kind of embodiment.
Described speed of a motor vehicle counter structure is located on wheel (sign), and described wheel comprises rotating shaft 21 and wheel Hu 23, and the described Hu of wheel 23 is fixed on described rotating shaft 21.Described counter 1 is located in described rotating shaft 21 and describedly takes turns between Hu 23.
Described counter 1 comprises rotor 11, counter housing 13 and oil sealing 15.Described rotor 11 is sheathed in described rotating shaft 21.Described counter housing 13 is sheathed on described rotor 11.Described oil sealing 15 is sheathed on described counter shell 13 surface.Described rotor 11, counter housing 13 and described oil sealing 15 are located in described rotating shaft 21 and describedly take turns between Hu 23.
Described rotor 11 abuts car rotation 21 and arranges, for detecting the revolution of described rotating shaft 21.
Described counter housing 13, in arc-shaped, is sheathed on outside described rotor 11.Described counter shell 13 entirety is in hollow cylindrical, and described rotor 11 and described rotating shaft 21 are contained in the hollow position of described counter housing 13.Described counter housing 13 comprises accepting groove 131, and described accepting groove 131 is located at the end surface of described counter housing 13, and described accepting groove 131 coordinates the surperficial forming station scalariform of described counter housing 13.Described counter housing 13 adopts engineering plastics to process.
Referring to Fig. 2 again, is the close-up schematic view of a-quadrant shown in Fig. 1.Described oil sealing 15 is annulus, and it is sheathed on the outer surface of described counter housing 13, and is contained in described accepting groove 131.Described oil sealing 15 comprises body 150, main lip 151, secondary lip 153 and opening 155.Described body 150 and described main lip 151, secondary lip 153 integrative-structure.Described main lip 151, described secondary lip 153 from described body 150 outer surface towards extended away from described body 150 direction.Described main lip 151 coordinates described secondary lip 153 in acute angle sandwiched, and surrounds described opening 155.Described opening 155 takes turns Hu 23 towards described.Described main lip 153 and described secondary lip 155 abut describedly takes turns Hu 23 inside surface.Meanwhile, described oil sealing 15 is arranged with described Hu 23 interference fit of taking turns.
