CN201561029U - Combined type tyre nut - Google Patents

Abstract

The utility model discloses a combined type tyre nut, comprising a nut and also comprising a movable washer; the axial end of the movable washer is movably sheathed and riveted together with the corresponding end of the nut, the movable washer can rotate relatively to the nut, and the other axial end of the movable washer is provided with a hollow cylinder in an extending manner. By adopting the technical scheme, and when the combined type tyre nut is assembled, the hollow cylinder of the movable washer is sheathed into a gap between a screw rod of a tyre bolt assembly and a hub bolt hole; the nut and the movable washer are sheathed by a convex ring and a groove and are riveted and fixed; the nut and the movable washer can be fixed together in a relatively rotating manner; the hollow cylinder leads the gap between the bolt hole and the screw rod to be extremely small, the wheels are not easy to form irregular operation when in running, therefore, the shearing force generated to the tyre bolt assembly of an automobile is less when the automobile bumps, vibrates, brakes and impacts, and the fracture of the tyre bolt is avoided, thus prolonging the service life of the hub bolt assembly.

Description

A kind of combined type tyre nut

Technical field

The utility model relates to a kind of assembly parts of bolt assembly of used for vehicle tyre, particularly a kind of lug nut.

Background technique

At present, known dismounting for the ease of wheel, the screw diameter of automobile tire bolt combination part is generally than the little 4～6mm of boss bolt bore dia.Because the factor of diameter difference, wheel hub after the installation causes that easily wheel hub center line and wheel center line can not be on same axis, cause wheel when walking, to form irregular running, automobile easily produces great shearing force to automobile tire bolt combination part when jolt vibration and brake are impacted like this, thereby cause tire bolt to fracture, shortened the working life of boss bolt assembly.

The model utility content

The purpose of this utility model provides a kind of boss bolt assembly combined type tyre nut in working life that prolongs.

The technical solution of the utility model is such: a kind of combined type tyre nut, comprise nut, also comprise driving washer, an axial end of above-mentioned driving washer and the respective end pivot bush unit of above-mentioned nut also rivet together, and above-mentioned driving washer can rotate relatively with above-mentioned nut, and the axial the other end of above-mentioned driving washer has extended hollow cylinder.

Convex with the circular cylindrical projection ring on the end outside that above-mentioned nut and above-mentioned driving washer socket-connect, be concaved with on the corresponding end-faces of above-mentioned driving washer and the suitable groove of the cylindrical bulge loop of nut, and the groove depth of this groove is slightly larger than the thickness of above-mentioned cylindrical bulge loop.

After adopting technique scheme, a kind of combined type tyre nut of the present utility model, during assembling, the hollow cylinder of driving washer is inserted between the screw rod of tire bolt assembly parts and hub stud holes in the existing gap, nut and driving washer socket-connect and rivet together by bulge loop and groove, and nut and driving washer can be fixed together with the relative rotation; Make bolt hole and the screw rod gap between the two very little by hollow cylinder, make wheel when walking, be difficult for forming irregular running, automobile is less to automobile tire bolt combination part generation shearing force when jolt vibration and brake are impacted like this, avoid the tire bolt phenomenon that fractures, thereby prolonged the working life of boss bolt assembly; Because the groove depth of driving washer upper groove is slightly larger than the thickness of bulge loop on the nut, nut is inserted in the driving washer and during riveted like this, the cell wall of groove stretches out part beyond the bulge loop to the bending of the axle center of driving washer and be fitted in riveted on the ear end face of bulge loop, be that nut connects together with driving washer more securely, thereby make automobile nut and the difficult disengaging of driving washer when jolt vibration and brake are impacted.

Fig. 2 does not rivet preceding three-dimensional exploded view for the utility model.

Embodiment

A kind of combined type tyre nut of the present utility model, as shown in Figure 1, 2, comprise nut 1 and driving washer 2, convex with circular cylindrical projection ring 11 on the axial end outside that nut 1 and driving washer 2 socket-connect, be concaved with the groove 21 suitable on the corresponding end-faces of driving washer 2 with cylindrical bulge loop 11, and the groove depth of this groove 21 is slightly larger than the thickness of bulge loop 11, and the axial the other end of driving washer 2 has extended hollow cylinder 22.

When assembling, the hollow cylinder 22 of driving washer 2 is inserted between tire screw rod and hub stud holes in the existing gap, nut 1 rivets together with the mutual chimeric socket of driving washer 2 by bulge loop and groove 21, when nut 1 and driving washer 2 riveteds, the cell wall of groove 21 stretches out part beyond the bulge loop 11 to place, the axle center bending of driving washer 2 and be fitted in riveted on the ear end face of bulge loop 11, and driving washer 2 can rotate relatively with nut 1.Make bolt hole and the screw rod gap between the two very little by hollow cylinder 22, make wheel when walking, be difficult for forming irregular running, automobile is less to automobile tire bolt combination part generation shearing force when jolt vibration and brake are impacted like this, avoid the tire bolt phenomenon that fractures, thereby prolonged the working life of boss bolt assembly; Because the groove depth of driving washer 2 upper grooves 21 is slightly larger than the thickness of bulge loop 11 on the nut, nut 1 is inserted in the driving washer 2 and during riveted like this, the cell wall of groove 21 stretches out part beyond the bulge loop 11 to place, the axle center bending of driving washer 2 and be fitted in riveted on the ear end face of bulge loop 11, be that nut 1 connects together with driving washer 2 more securely, thereby make automobile nut 1 when jolt vibration and brake are impacted be difficult for breaking away from driving washer 2.

Claims (2)

1. combined type tyre nut, comprise nut, it is characterized in that: also comprise driving washer, an axial end of above-mentioned driving washer and the respective end pivot bush unit of above-mentioned nut also rivet together, and above-mentioned driving washer can rotate relatively with above-mentioned nut, and the axial the other end of above-mentioned driving washer has extended hollow cylinder.

2. a kind of combined type tyre nut according to claim 1, it is characterized in that: convex with the circular cylindrical projection ring on the end outside that above-mentioned nut and above-mentioned driving washer socket-connect, be concaved with on the corresponding end-faces of above-mentioned driving washer and the suitable groove of the cylindrical bulge loop of nut, and the groove depth of this groove is slightly larger than the thickness of above-mentioned cylindrical bulge loop.
