Description

Wheel tyre of vehicle with skid tooth

The utility model relates to a kind of gripping wheel tire construction, especially refers to travel adapt to anti-skidding and the anti-skidding automoblie tyre that changes of antiskid pavement not at needs.

At present, common automoblie tyre anti-skidding be mostly common wheel outer rim suit anti-slop serrations or on wheel hub dress band tooth wheel in addition, loading and unloading trouble, and structure is also complicated can not adapt to ground-surface at any time and change (need anti-skidding and do not need antiskid pavement).

In view of this, the purpose of this utility model provides a kind of automoblie tyre with anti-slop serrations, and anti-slop serrations is dismounting easily, and structure is simple again.

The purpose of this utility model is achieved in that it comprises tire, anti-slop serrations piece, also is provided with substrate, seat board, bearing pin, compression spring and fork in the groove of tire; Wherein substrate is embedded in the tire bottom portion of groove with the edge, elongated slot is arranged in the middle of the seat board, there is half-open circular hole on the upper left side, and be connected on the substrate, the anti-slop serrations piece places in the elongated slot of seat board, and with the following inwall vertical slot bottom of its lower end projection against elongated slot, bearing pin one end bearing is in seat board upper end-face edge vertical core, the other end is at the bottom of the anti-slop serrations piece upper end hole, and the bearing pin centre has only a shoulder, compression spring is arranged between the shoulder upper surface and base plate upper end-face edge of bearing pin, fork has rotating shaft and lever arm, its shaft activity is engaged in the half-open circular hole of base plate, and the pipe spreader of lever arm is enclosed within on the bearing pin, and an end face is resisted against the shoulder lower surface of bearing pin.

Owing to adopt such scheme: can adapt to the road surface rapidly and change (ice and snow is arranged and do not have ice and snow road), structure is simple again, and is with low cost.

The structural representation of Fig. 1 the utility model embodiment.

The A-A cutaway view of Fig. 1 of Fig. 2 the utility model embodiment.

Among the figure: 1, tire, 11, groove, 2, substrate, 3, seat board, 31, elongated slot, 32, half-open circular hole, 33, screw, 34, vertical slot, 35, vertical core, 4, the anti-slop serrations piece, 41, lower end projection, 42, upper end hole, 43, the end face tooth, 5, bearing pin, 51, shoulder, 6, compression spring, 7, fork, 71, rotating shaft, 72, lever arm.Evenly water half that outpours several grooves 11(depth of groove and be about tire thickness on the wheel rim of tire 1).

Substrate 2 is groove 11 bottoms that place tire 1, and its edge is embedded in the steel plate in the tire 1.

Seat board 3 for middlely have elongated slot 31, the upper left side has half-open circular hole 32 and upper limb and elongated slot 31,32 of half-open circular holes that the steel plate that hollows out the edge is arranged, and be connected above the interior substrate 2 of the groove 11 of tire 1 with screw 33.In addition, seat board 3 hollows out and connects a closed cover (not shown) above the hole to hide dust and to prevent that other part flies out.

Anti-slop serrations piece 4 has the metal-toothed piece of lower end projection 41, upper end hole 42 and end face tooth 43.Square or the oblong of lower end projection 41() the elongated slot 31 lower inner wall vertical slots 34 with seat board 3 match, and projection 41 terminations in lower end contact with vertical slot 34 bottoms; Upper end hole 42(circular hole) cooperate with an end of bearing pin 5, and bearing pin 5 terminations contacts with upper end hole 42 bottoms; End face tooth 43(triangle, trapezoidal or square) top contacts with ice and snow ground, slides to reach anti-; Anti-slop serrations piece 4 length are shorter than elongated slot 31.Bearing pin 5 is middle sliding pins that shoulder 51 is arranged, and wherein an end inserts in the upper end hole 42 of anti-slop serrations piece 4, and the other end is bearing in the seat board 3 upper end-face edge vertical cores 35.

Compression spring 6(spiral steel wire spring) is arranged between shoulder 51 upper surfaces and base plate 3 upper end-face edges of bearing pin 5.

Fork 7 has rotating shaft 71 and lever arm 72 constitutes one, rotating shaft 71 cooperates with half-open circular hole 32 activities of seat board 3, and lever arm 72 top sleeve skies are enclosed within on the bearing pin, and an end face is against shoulder 51 lower surfaces, the square socket that spanner is arranged in the rotating shaft 71, as long as with spanner clockwise direction rotating shaft 71, lever arm 72 promotes shoulder 51 compression springs 6, bearing pin 5 moves up, the upper end hole 42 of throwing off anti-slop serrations piece 4 until an end, again because anti-slop serrations piece 4 length are shorter than elongated slot 31, therefore, anti-slop serrations piece 4 can take out, and changes lastblock and does not have end face tooth 42, other geomery and anti-slop serrations piece 4 identical sprue (not shown) are put into and are replaced anti-slop serrations piece 4, adapt to not that wheel travels on the skidproof road surface of needs.
