Embodiment Construction
[0012] see figure 2 , The hanging structure is composed of a base 1, a spherical shell cover 2, a rubber ball 3 and a metal hook 4. Wherein the base 1 is a rectangular steel, one side of which is machined into a spherical groove, and the other side is used for welding with the vehicle body. The spherical shell cover 2 is stamped from a steel plate, and is connected with the base 1 by bolts 6 . Cover the spherical groove. There is a hollow draw-in groove inside the rubber ball 3 for socketing with the cap head 5 of the hook 4 . The rubber ball 3 is assembled in the spherical groove of the base 1, the hook 4 passes through the center hole of the spherical shell cover 2, the base 1, the spherical shell cover 2 and the rubber ball 3 form a spherical hinge structure, so that the rubber ball 3 can be placed in the spherical groove It can freely rotate inside, so as to relieve the rotational movement in the three directions of X, Y and Z axes. Since the rubber ball 3 has elastic...

The invention relates to a silencer suspended structure, which is composed of a base, a spherical semi-housing cover, a rubber ball and a metal hanger, wherein, the base is welded with a vehicle body; a spherical groove is processed on the base; one end of the metal hanger is welded with the silencer; the cap head of the other end of the metal hanger stretches into the rubber ball and is locked with the rubber ball; the rubber ball is arranged in the spherical groove, and the spherical groove is covered by the spherical housing cover which is fixed on the base through a bolt; the metal hangerpenetrates through the central hole of a spherical housing cover; a spherical hinge structure is formed by the base, the spherical housing cover and the metal hanger; the rubber ball can rotate freely in the groove, thus relieving the rotary motion along three directions of X axis, Y axis and Z axis; as the radius of the spherical groove is larger than that of the rubber ball, and the rubber ballhas elasticity, and also can move along the X, Y and Z directions, thus relieving the vibration of the silencer in the X, Y and Z directions by moving along the X, Y and Z directions. The structure is simple, has convenient assembling, can effectively relieve the vibration of silencers, and has more excellent decoupling effect.
Description
technical field [0001] The invention is a suspension structure applied to an automobile muffler and capable of effectively alleviating the vibration of the muffler. Background technique [0002] As users have higher and higher requirements for comfort and product quality, this requires the muffler to transmit smaller and smaller vibrations to the body, and to meet the requirements of complex working conditions and harsh environments. Because the muffler is affected by engine vibration and bumpy road conditions, it vibrates greatly, and severe vibration will affect the reliability of the muffler; at the same time, the severe vibration of the muffler will be transmitted to the vehicle body through the suspension structure. Such vibrations can be uncomfortable for the occupants of the vehicle if appropriate decoupling measures are not taken. The currently used muffler suspension structure is a rubber cushion 7, see figure 1 , although this kind of cushion can alleviate the vi...
