Description

Technical Field

[0001] The utility model relates to the technical field of the outer wheel of an automobile transmission shaft, in particular to an outer wheel assembly of a transmission shaft. Background Art

[0002] The outer wheel of the transmission shaft refers to the component responsible for connecting the transmission shaft and the vehicle tire in the automobile transmission system. It can keep the transmission shaft stable during steering, thereby reducing vibration and frictional loss. While ensuring the transmission efficiency, this assembly can also keep the vehicle stable during turning and can adapt to turns at different angles.

[0003] When the outer wheel of the automobile transmission shaft is in use, it is necessary to waterproof and dustproof the outer wheel of the automobile transmission shaft. A rubber elastic sleeve is used to seal and wrap the rod part of the outer wheel of the automobile transmission shaft. However, the rubber elastic sleeve does not rebound after being folded for a long time, which easily causes the rod part of the outer wheel of the automobile transmission shaft to be exposed and affected by mud, water and sundries. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an outer wheel assembly of a transmission shaft, which has the advantages of preventing the telescopic protective sleeve from not rebounding after folding, and the rod part of the outer wheel body of the transmission shaft from being exposed and unable to perform dustproof and waterproof functions, and solves the problem that the rubber elastic sleeve is used to seal and wrap the rod part of the outer wheel of the automobile transmission shaft, but the rubber elastic sleeve does not rebound after being folded for a long time, which easily causes the rod part of the outer wheel of the automobile transmission shaft to be exposed and affected by mud, water and sundries.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an outer wheel assembly of a transmission shaft, including an outer wheel body of the transmission shaft, a bolt and a connecting block. One side of the outer wheel body of the transmission shaft penetrates through a telescopic protective sleeve, and one side of the outer wheel body of the transmission shaft penetrates through a nut and is threadedly connected. A bracket is fixed at the upper end of one side of the outer wheel body of the transmission shaft. A long plate is installed in the bracket. A long groove is formed on the lower surface of the long plate. The connecting block is inserted into the long groove. A moving plate is fixed on the lower surface of the connecting block. A limiting ring is fixed on the lower surface of the moving plate. A through hole is formed on one side of the limiting ring. One side of the telescopic protective sleeve penetrates through the through hole, and one side of the limiting ring fits against the outer wall of the telescopic protective sleeve.

[0006] Preferably, a protective hole is formed on one side of the telescopic protective sleeve, and one side of the outer wheel body of the transmission shaft penetrates through the protective hole. The protective hole facilitates the penetration of one side of the outer wheel body of the transmission shaft, so that the round rod part of the outer wheel body of the transmission shaft can be wrapped by the protective hole, which is convenient for protecting the outer wheel body of the transmission shaft.

[0007] Preferably, a groove is formed on the upper surface of the bracket, and threaded holes I are respectively formed at the front and rear ends of the bracket. Threaded circular grooves are respectively formed at the front and rear ends of the long plate. The rear end of the bolt passes through the threaded hole I and extends into the threaded circular groove, and is threadedly connected. By passing the rear end of the bolt through the threaded hole I and extending it into the threaded circular groove and threadedly connecting them, the long plate can be limited, and at the same time, the limiting ring can limit the telescopic protective sleeve.

[0008] Preferably, a threaded hole II is formed on one side of the connecting block, a circular hole is formed on one side of the long plate, a rotating rod extends into the circular hole and is rotatably connected. A threaded rod is fixed on one side of the rotating rod, and one side of the threaded rod passes through the threaded hole II and is threadedly connected. By rotating the rotating rod, power is provided for the rotation of the threaded rod, so that the connecting block and the limiting ring can move as needed, so that the limiting ring can fit the outer wall of the telescopic protective sleeve to limit the telescopic protective sleeve, preventing the telescopic protective sleeve from folding and not rebounding, resulting in the exposure of the rod part of the outer wheel body of the transmission shaft and inability to perform waterproof and dustproof functions.

[0009] Preferably, the width of the long groove formed on the lower surface of the long plate matches the width of the connecting block. By making the width of the long groove match the width of the connecting block, the long groove can limit the connecting block, prevent the threaded rod from rotating and the connecting block from rotating along with it, and facilitate the movement of the connecting block.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] In the present utility model, one side of the outer wheel body of the transmission shaft passes through the nut and is threadedly connected. A bracket is fixed at the upper end of one side of the outer wheel body of the transmission shaft. A long plate is installed in the bracket. A long groove is formed on the lower surface of the long plate. A connecting block is inserted into the long groove. A moving plate is fixed on the lower surface of the connecting block. A limiting ring is fixed on the lower surface of the moving plate. A through hole is formed on one side of the limiting ring. One side of the telescopic protective sleeve passes through the through hole. One side of the limiting ring fits the outer wall of the telescopic protective sleeve. When it is necessary to protect the outer wheel body of the transmission shaft, pass one side of the outer wheel body of the transmission shaft through the telescopic protective sleeve, then install the long plate in the bracket, and then rotate the rotating rod. The threaded rod rotates, and the limiting ring moves to limit one side of the telescopic protective sleeve, achieving the effect of preventing the telescopic protective sleeve from folding and not rebounding, the rod part of the outer wheel body of the transmission shaft being exposed, and being unable to perform dustproof and waterproof functions.
