Detailed Description
As shown in fig. 1 and 2, the connecting device of the non-pneumatic tire and the testing equipment is a rotating body, so that the rotating stability during subsequent tests can be ensured. The connecting device comprises a rear end fixing seat 1, a middle connecting seat 2 and a front end mounting seat 3. Be provided with a plurality of first through-holes 11 along circumference distribution on the rear end fixing base 1, first through-hole 11 runs through the front and back both sides of rear end fixing base 1. Middle part connecting seat 2 sets up in the front side of rear end fixing base 1, is provided with the second through-hole 21 with first through-hole 11 coaxial on middle part connecting seat 2, and the aperture of second through-hole 21 is greater than first through-hole 11. The second through holes 21 penetrate through the front and rear sides of the middle connection seat 2. The middle connecting seat 2 is further provided with a plurality of threaded holes 22 distributed along the circumferential direction. Front end mount pad 3 sets up the front side at middle part connecting seat 2, and front end mount pad 3 is the cylindricality of axis level setting, and the outer disc of front end mount pad 3 is located the inboard of the ring that a plurality of screw holes 22 formed. The front end mount 3 is used to attach to the center hole of a non-pneumatic tire. A connecting part 5 is arranged between the rear end fixing seat 1 and the middle connecting seat 2, and the axial length of the connecting part 5 is used for compensating offset distance and horizontally centering the non-pneumatic tire. Preferably, the outer circumferential surface of the connecting portion 5 is located inside the circular ring formed by the plurality of first through holes 11.
The center of the connecting device is provided with third through holes 4 which penetrate through the front side and the rear side, so that the weight of the connecting device is reduced.
The outer edge of the rear side of the rear end fixing seat 1 is provided with a positioning flange 12 extending towards the rear side.
The connecting device adopts 45# steel, so that the connecting device has higher strength and deformation resistance, and can ensure stable performance when the connecting device rotates at high speed and under high load after being connected with a tire.
In the test equipment, the spoke of the detection special rim is positioned on the central plane of the tire, while the spoke of the non-pneumatic tire is often not detachable and is offset, and under the condition that the testing machine has no centering compensation function, the mounted non-pneumatic tire needs to be centered through the connecting device, even if the central plane of the non-pneumatic tire is positioned on the horizontal central line of the test station or the runway.
To achieve the above object, the horizontal distance between the center hole of the spoke and the center of the tread of the non-pneumatic tire is measured, and then a connecting device having a connecting portion 5 of an appropriate length is selected based on the measured value, and then the connecting device is connected to a testing machine. During connection, the screw penetrates through the second through hole 21 and the first through hole 11 in sequence, the aperture of the second through hole 21 is larger than the diameter of the head of the screw, and the second through hole 21 has the function of enabling the connecting screw to smoothly reach the position of the first through hole 11. The first through hole 11 is aligned with a mounting screw hole on the testing device, and then a screw is screwed in the mounting screw hole to fix the connecting device on the testing machine. The tire is then mounted to the attachment device, and the non-pneumatic tire is secured to the attachment device by screws passing through the bolt holes of the non-pneumatic tire and engaging the threaded holes 22 during installation. The diameters of the first through hole 11, the threaded hole 22 and the front end mounting base 3 need to be matched with the mounting threaded hole of the testing machine, the bolt hole of the tire and the central hole of the tire respectively, so that the positioning, accurate connection and stability of the tire are ensured, and relative sliding is not generated during rotation.
