Description
VEHICLE WHEEL NOISE-REDUCING DAMPER
FIELD OF THE DISCLOSURE
[0001] This invention concerns a noise-reducing damper used to reduce the noise arising from running track wheels.
BACKGROUND
FIELD OF THE DISCLOSURE
[0001] This invention concerns a noise-reducing damper used to reduce the noise arising from running track wheels.
BACKGROUND
[0002] One of the current noise-reducing methods is to install a damper on the wheel which absorbs the vibration energy from the wheel so as to increase the vibration damping, reduce noise radiation, and decrease the oscillation amplitude of the wheel. As such, the goal of reducing running noise can be achieved.
[0003] The noise-reducing damper is made of metal and comprised of a noise-reducing damping ring and a connector. The damper is installed in a ring-shaped groove. To install this damping ring, an open section of the ring and a connector which connects the open section is required. Patent (CN200920179686.2) published a wheel noise-reducing damper which has one damping ring and a connector that connects the two ends of the open section of the ring through two holes at each end. A closed ring-shaped noise-reducing damper is then made. But the connection between the ring and the connector requires heave-duty adhesive and the connected area is limited, which affect the stability of the connection, the effect of noise reduction and the safety. For the long-term use, the effect of noise reduction will gradually diminish and new noise may also arise as wear occurs between the damping ring and the groove.
BRIEF SUMMARY OF THE INVENTION
BRIEF SUMMARY OF THE INVENTION
[0004] The objective of this invention is to provide a noise-reducing damper which can overcome the shortcomings of the current technology, better reduce the running noise of the wheel and ensure effective connection between the damping connector and the open ends of the damping ring. The noise-reducing damper provides adequate compensation for the open ends and utilizes the centrifugal force the spinning wheel to improve the effect of noise reduction during the running of the vehicle. By doing so the noise reduction effect and safety can be maintained even there is wearing in the damping ring.
[0005] In this invention, the noise-reducing damper has a damping connector and ring.
[0006] The open section of the damping ring has an angled plane or ladder-shaped surface; the damping connector has a pipe-shaped object which is slightly shorter than the length of the open section of the damping ring; at the two ends of the pipe-shaped object are two locating objects, which on one side has a bar that can go through the end of the pipe-shaped object, and on the other side has angled plane or ladder-shaped surface matching the end of the open section of the damping ring. Inside the pipe-shaped object, there is a spring which can push out the two locating objects. The locating object has a locating hole which is used to fix the location of the locating object by inserting a bar from outside the pipe-shaped object into the hole; when the bar is pulled out the two locating objects will be pushed out and stay connected with the damping ring.
[0007] During the installation of the damper, the damping ring is installed into the groove on the wheel with its open section being connected through matching the angled planes or ladder-shaped surfaces between the connector and the ring. With the interacting effect occurring in the axial, radical and peripheral directions, the damping ring and the connector are strongly attached to the wheel.
[0008] The shape of the pipe-shaped object can be adjusted to a certain degree of radian so as to provide maximized noise reduction and strengthen the location of the connector as well as making the running of the wheel more safe and stable.
