a shock absorber

Abstract

The invention discloses a shock absorbing device, which comprises a belt pulley, a vehicle frame, a V-belt, a bearing seat, a lower shock absorbing pad, an isolation plate, an upper shock absorbing pad, a pressing plate and a pressing plate adjusting bracket. In the present invention, an isolation plate is installed between the bearing seat and the lower shock-absorbing pad, and upper shock-absorbing pads and pressure plates are installed on both sides of the isolation plate. Compression and deformation, at the same time, the upper shock pad generates an upward thrust, which is pushed back by the pressure plate, and then transmitted to the lower shock pad by the isolation plate, so that the lower shock pad receives an upward pull and a downward thrust at the same time, and most of them are affected. The force is offset, so that the tensile deformation of the rubber block of the lower shock-absorbing pad is reduced, thereby improving the life of the shock-absorbing pad, reliable shock absorption, and improving the working stability of the operating device.

Description

technical field [0001] The invention relates to the related field of shock absorbing devices, in particular to a shock absorbing device. Background technique [0002] Sweeping vehicles refer to vehicles that undertake the cleaning, washing, and cleaning operations of roads such as urban areas, national highways, and expressways, and the transmission mechanism of the cleaning vehicle is usually equipped with a shock absorber for shock absorption. [0003] At present, in the transmission mechanism, the two pulleys are installed in an up-and-down structure, and the space position of the upper fan pulley is fixed. After the belt is tensioned, there is always an upward pulling force on the engine pulley, and the pulling force is transmitted to the bearing seat and the lower shock pad at the same time. Coupled with the continuous vibration generated by the engine and fan, the upper plate of the shock-absorbing pad under the bearing seat bears an upward pull, and the lower plate is...

Problems solved by technology

[0003] At present, in the transmission mechanism, the two pulleys are installed in an up-and-down structure, and the space position of the upper fan pulley is fixed. After the belt is tensioned, there is always an upward pulling force on the engine pulley, and the pulling force is transmitted to the bearing seat and the lower shock pad at the same time. Coupled with the continuous vibration generated by the engine and fan, the upper plate of the shock-absorbing pad under the bearing housing bears an upward pull, and the lower plate is quickly fixed by bolts. The plate is separated, resulting in the failure of shock absorption. At the same time, the pulley of the bearing seat is in a semi-free state, which cannot effectively transmit power, and the reliability of the operating device is affected.
