Problems solved by technology
[0002] At present, the flipping brackets connected between the frame and the cab of the car are equipped with vibration-damping sleeves. The traditional vibration-damping sleeves are made of rubber vulcanization between the outer frame sleeve and the inner frame sleeve to form a sleeve body. Since the rubber body is a solid The rigidity of the colloid cannot meet the real vibration reduction requirements. During the long-term use of the vehicle, the colloid will age, and the solid rubber will have a greater rigidity, which will cause the vehicle to vibrate when driving, and will cause the overturn bracket to fail. Early damage or abnormal noise, in severe cases, will endanger the safety of passengers or cause economic losses

Embodiment Construction
[0028] attached figure 1 Shown: several damping holes are arranged on the colloid 3 .
[0029] attached figure 2 As shown: the vibration-damping hole is a fully transparent vibration-damping hole 4 crossing the colloid 3 or a semi-transparent vibration-damping hole 5 horizontally placed in the middle of the colloid 3 .
[0030] attached Figures 3 to 18 Shown: the damping holes provided are elliptical damping holes 6, bone-shaped damping holes 7, arc-shaped damping holes 8, circular damping holes 9 and square damping holes 10.
[0031] When implementing this technical solution, the various forms of damping holes are mainly set according to the needs of different models of various vehicles. The various forms of damping holes can be formed at one time when the rubber is vulcanized, or they can be formed in the solid core of the damping sleeve. The colloid is additionally punched and set.

The invention provides a vibration-damping sleeve of an overturn support of a car. A plurality of vibration-damping holes are formed in a rubber body, the vibration-damping holes are the all-through vibration-damping holes which penetrate the rubber body transversely or the half-through vibration-damping holes which are formed in the middle of the rubber body transversely, and the vibration-damping holes comprise the oval vibration-damping holes, the bony vibration-damping holes, the arc strip-shaped vibration-damping holes, the round vibration-damping holes and the square vibration-damping holes. By the aid of the vibration-damping holes, the vibration damping performance of the vibration-damping sleeve can be optimized comprehensively, the overall comfort of the car is good, damage caused by excessive rigidity to other components during car operation can also be avoided, and the overturn support is safe.
Description
technical field [0001] The invention relates to a vibration-damping sleeve used for an automobile overturning bracket, in particular to a vibration-damping sleeve for an automobile overturning bracket. Background technique [0002] At present, the flipping brackets connected between the frame and the cab of the car are equipped with vibration-damping sleeves. The traditional vibration-damping sleeves are made of rubber vulcanization between the outer frame sleeve and the inner frame sleeve to form a sleeve body. Since the rubber body is a solid The rigidity of the colloid cannot meet the real vibration reduction requirements. During the long-term use of the vehicle, the colloid will age, and the solid rubber will have a greater rigidity, which will cause the vehicle to vibrate when driving, and will cause the overturn bracket to fail. Early damage or abnormal noise will endanger the safety of passengers or cause economic losses in severe cases. Contents of the invention ...
