Description

Technical Field

[0001] The utility model relates to the technical field of automobile detection, in particular to a wheel dynamic balance testing device. Background Art

[0002] The wheel dynamic balance test device is used to detect the imbalance and angular position of the tire surface. After the test, the tire can be balanced according to the test results to ensure that the tire itself does not shift its center of gravity when rotating, thereby improving driving safety and increasing the service life of the tire.

[0003] When the tire is installed outside the dynamic balancing test device for rotation test, the tire is mostly in a completely exposed or semi-exposed state. The dynamic balancing test device cannot completely wrap the tire. The dust sticking on the tire surface can easily spread around due to the influence of rotation and centrifugation. Even stones stuck in the anti-skid grooves can be thrown around by rotation, affecting the operating environment of the staff, causing serious safety hazards and great inconvenience. Utility Model Content

[0004] Based on the above description, the utility model provides a wheel dynamic balance test device to solve the problem that the existing dynamic balance test device cannot completely wrap and protect the tire during the rotation test, resulting in dust and stones being easily thrown around due to the centrifugal effect of rotation during the test.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the rotating shaft is composed of a balancing shaft and a fixed cone block, the balancing shaft is installed on the surface of the balancing machine housing, the fixed cone block is installed on the end of the balancing shaft surface away from the balancing machine housing, and the tire is inserted into the outside of the balancing shaft and installed on the end of the fixed cone block away from the balancing machine housing.

[0008] Furthermore, the threaded member is composed of an external threaded sleeve and a bearing. The external threaded sleeve is installed on the surface of the balancing machine housing and is located on the outside of the balancing shaft. The bearing is installed between an inner end of the external threaded sleeve and the surface of the balancing shaft.

[0009] Furthermore, the protective member is composed of an internal threaded sleeve and a protective cover, wherein the internal threaded sleeve is installed on the outside of the external threaded sleeve, and the protective cover is installed on one end of the internal threaded sleeve away from the balancing machine housing and wrapped around the outside of the tire.

[0010] Furthermore, pull rods are installed on the outer side of the internal threaded sleeve, and the pull rods are distributed in a circular shape with equal distances around the center of the internal threaded sleeve.

[0011] Furthermore, a rubber edge strip is installed on one side of the protective cover away from the balancing machine chassis. The rubber edge strip is arc-shaped with its inner arc surface facing the inside of the protective cover. The rubber edge strips are distributed in a circular shape with equal distances around the center of the protective cover.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0013] The utility model uses an external thread sleeve and a bearing, an internal thread sleeve and a protective cover. The internal thread sleeve is arranged at one end of the protective cover and is threadedly connected to the external thread sleeve. When in use, the protective cover can be rotated on the thread outside the external thread sleeve through the internal thread sleeve, and horizontally moved along the balance shaft. When the tire is installed on the outside of the balance shaft for dynamic balancing test, the protective cover can be horizontally moved to the outside of the tire to wrap it, and dust and stones thrown to the surroundings during the rotation of the tire are collected inside to avoid spreading to the surroundings and causing influence. The operation method is simple and does not affect the disassembly and assembly operation of the tire. BRIEF DESCRIPTION OF THE DRAWINGS
