Summary of the invention:
The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of safety vehicle wheel hub with annular knurl, and it has the advantage of portable construction, safe and reliable, stable performance.
Technology solution of the present utility model is as follows: a kind of safety vehicle wheel hub with annular knurl, comprise wheel rim, middle hub and the spoke for connecting described wheel rim and middle hub, at two ends, side, convex peak is provided with bead seat to described wheel rim, the clinoplane of described bead seat is provided with annular knurl band, one end face of described wheel rim is fixedly installed valve port, the bilateral symmetry of described valve port is provided with grooving, described middle hub subpanel is at least provided with one and draws hopper, described both sides of drawing hopper are provided with drainage channel, described drainage channel and described to draw hopper mutually through, and described drainage channel extends along the radial direction of described middle hub.
Preferred as technique scheme, the width of described annular knurl band is less than or equal to the width of described bead seat clinoplane, and minimum width is preferably 3.5mm.
Preferred as technique scheme, the degree of depth of described annular knurl band is preferably 0.1 ~ 0.5mm.
Preferred as technique scheme, described annular knurl band is provided with some annular knurls uniformly, and one end of described annular knurl is provided with bevel angle, and described bevel angle is preferably 30 °.
Preferred as technique scheme, the angle α between described bead seat clinoplane and wheel rim center shaft is preferably 5 °.
Preferred as technique scheme, described middle hub subpanel is provided with five and draws hopper, described in draw hopper and be evenly distributed on circumferentially same.
Preferred as technique scheme, the described degree of depth drawing hopper is preferably 5 ~ 20mm.
Preferred as technique scheme, described spoke is in " work " font.
The beneficial effects of the utility model are: by arranging annular knurl band at the two ends of wheel rim, annular knurl one end on described annular knurl band is provided with bevel angle, such tire after mounting and there is an additional fastening effect between wheel hub, effectively can increase the friction force between wheel rim and tire, effective guarantee tire is with the installation compatible degree between wheel hub and prevent tire and operating relative the trackslipping of wheel hub from coming off, and can improve the safety performance of whole wheel;
The bilateral symmetry of valve port is provided with grooving, and a balanced compensated effect is also played in grooving while alleviating hub weight; Middle hub subpanel is provided with and draws hopper and drainage channel, draw hopper and drainage channel be arranged on loss of weight while can also ensure the balance quality that wheel hub is good, and transmission portion corrosion can be prevented by the sewage of effectively discharging in wheel hub.
