Accordingly, the automobile hub 100 according to the embodiment of the present utility model has an advantage of improving the safety of driving an automobile.
As shown in fig. 1 to 8, in some embodiments, a third rim 4 is provided on the second rim 3. In particular, the third rim 4 is connected to the outer edge of the second rim 3.
In some embodiments, the third rim 4 includes a cone sleeve section 41 and a wheel ring section 42.
As shown in fig. 1 to 8, the taper sleeve section 41 has an annular structure, the axial direction of the taper sleeve section 41 is a first direction, and the outer circumferential surface of the taper sleeve section 41 is a tapered surface, so that the taper sleeve section 41 has a preset dimension in the first direction. Specifically, the dimension of the drogue section 41 in the first direction is 20 millimeters or more. For example, the size of the cone sleeve segment 41 in the first direction is 30 millimeters.
The drogue section 41 has an annular first end and an annular second end in a first direction, the first end having an outer diameter that is smaller than the outer diameter of the second end. Specifically, the outer diameter of the sleeve segment 41 increases in a first direction away from the second rim 3, the first end being the end of the sleeve segment 41 having the smaller outer diameter and the second end being the end of the sleeve segment 41 having the larger outer diameter. The first end is connected to the second rim 3, i.e. the second rim 3 is connected to the end of the cone sleeve segment 41 having the smaller outer diameter. For example, the first end portion is connected to an outer edge (outer peripheral surface) of the second rim 3. For example, the outer diameter of the sleeve segment 41 increases rightward, and the left end of the sleeve segment 41 is the first end.
The annular ring section 42 is of an annular structure, the axial direction of the annular ring section 42 is the first direction, the outer diameter of the annular ring section 42 is larger than the outer diameter of the second rim 3, and the annular ring section 42 is connected with the second end of the taper sleeve section 41. Specifically, the thickness of the wheel ring section 42 is in the first direction, and the inner edge (inner peripheral surface) of the wheel ring section 42 is connected to the second end (outer edge) of the cone sleeve section 41, so that the outer diameter of the wheel ring section 42 can be made larger than the second rim 3. For example, the thickness of the wheel ring segment 42 is in the left-right direction.
As shown in fig. 1-8, in some embodiments, the third rim 4 includes a sleeve segment 43, the sleeve segment 43 being of annular configuration, the sleeve segment 43 being axially oriented in a first direction, the sleeve segment 43 being connected to an outer edge of the rim segment 42. Specifically, the taper sleeve section 41, the annular section 42 and the sleeve section 43 are connected in this order from inside to outside, and the thickness direction of the sleeve section 43 is the inside-outside direction.
The outer circumferential surface of the sleeve section 43 constitutes the outer circumferential surface of the third rim 4. Thereby, the outer peripheral surface of the sleeve section 43 can be brought into contact with the outside upon tire burst. The dimension of the sleeve section 43 in the first direction is equal to or greater than a first preset value, so that the peripheral surface of the sleeve section 43 in contact with the outside can be made larger, thereby facilitating the running of the automobile.
In some embodiments, the third rim 4 further comprises an outer ring section 44, the outer diameter of the outer ring section 44 being smaller than the outer diameter of the sleeve section 43, the outer ring section 44 being provided on the side of the sleeve section 43 facing away from the second rim 3. Specifically, the taper sleeve section 41, the wheel ring section 42, the sleeve section 43 and the outer ring section 44 are sequentially connected, and a transition section 45 is arranged at the joint of two adjacent sections of the taper sleeve section 41, the wheel ring section 42, the sleeve section 43 and the outer ring section 44, wherein the transition section 45 is a reducing section. The taper sleeve section 41, the wheel ring section 42, the sleeve section 43, the outer ring section 44 and the transition section 45 at the joint of the adjacent sections are integrally formed, so that the third wheel rim 4 is more stable in structure. For example, the reducing segment is an arc segment or a bevel segment.
In some embodiments, the third rim 4 is detachably provided on the second rim 3. For example, the third rim 4 is detachably provided on the second rim 3 by bolts.
In some embodiments, the third rim 4 is integrally formed with the second rim 3, so that the automobile hub 100 may be structurally stable.
As shown in fig. 6 to 8, the present utility model also proposes a vehicle tire according to an embodiment of the present utility model including a vehicle wheel hub 100 and a vehicle tire 200 (vehicle tire body) according to an embodiment of the present utility model, the third rim 4 of the vehicle wheel hub 100 having an outer diameter smaller than that of the vehicle tire 200.
Therefore, the automobile tire according to the embodiment of the utility model has the advantage of improving the safety of driving an automobile.
In some embodiments, the rim segment 42 of the third rim 4 is spaced apart from the vehicle tire 200. Specifically, the wheel rim section 42 of the third rim 4 is at a distance of 5 mm or more from the vehicle tire 200 in the first direction. Specifically, the distance between the rim section 42 of the third rim 4 of the inflated automobile hub 100 and the automobile tire 200 in the first direction is 5 mm or more. In this way, when the automobile passes over an uneven road surface and the automobile tire 200 is deformed by an impact by jolting up and down, the end face of the automobile tire 200 is only occasionally contacted with the adjacent face of the wheel rim section 42, so that the automobile tire 200 cannot generate heat in this area due to friction. The third rim 4 is not brought into contact with the road surface by the deformation of the outer circumference of the automobile tire 200 due to the vertical jounce of the automobile tire 200, and the automobile enters a normal running state. For example, the third rim 4 of the automobile hub 100 is spaced from the automobile tire 200 in the first direction by a distance of 10 mm.
In some embodiments, the ratio of the outer diameter of the third rim 4 to the outer diameter of the automobile tire 200 is (0.8-0.9): 1. for example, the outer diameter of the third rim 4 is 0.9 outside the outer diameter of the automobile tire 200: 1.
