A barrel type shock absorber

Abstract

The invention relates to a cylinder-type shock absorbing device, which belongs to the field of machinery. The device includes a cylinder body, a support plate, a SAW acceleration sensor, a shock-absorbing spring, an upper piston, a middle partition, a lower piston, a conductor assembly and a permanent magnet; the upper The piston is connected to the support plate through the piston rod; the SAW acceleration sensor is set under the support plate; the shock-absorbing spring ring is set outside the piston rod and between the support plate and the upper wall of the cylinder; the middle partition is welded on the inner wall of the cylinder; A damping channel is set on the middle partition, a stepping motor is set inside, and a damping adjustment plate is set on the top; the bottom of the lower piston is connected to a conductor assembly, which is connected to an external resistance through a wire; the conductor assembly is located in the magnetic field generated by the permanent magnet. The device can convert part of the mechanical energy into electric potential energy and consume it in the thermal energy of the metal conductor and the protective resistor, and convert the other part of the energy into the thermal energy between the hydraulic oil, the cylinder wall and the damping channel, thereby realizing three-part shock absorption, making the vibration The effect is more efficient.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a cylinder type damping device. Background technique [0002] With the continuous development and popularization of agricultural mechanization in our country, more and more agricultural machinery has been put into production and application. However, when these machines are used in actual production, they will inevitably produce a large amount of mechanical vibration, impact, friction and other mechanical forces. At the same time, these mechanical vibrations have brought harm that cannot be underestimated. For example, long-term mechanical vibration greatly reduces the fatigue strength of the machine, causing some mechanical components to be mechanically deformed due to the pressure of the vibration, or some bolt connections and other mechanisms on the machine are loosened by vibration, which reduces the mechanical strength. The use efficiency, even when reaching a certain r...

However, when these machines are used in actual production, they will inevitably produce a large amount of mechanical vibration, impact, friction and other mechanical forces. At the same time, these mechanical vibrations have brought harm that cannot be underestimated.

For example, long-term mechanical vibration greatly reduces the fatigue strength of the machine, causing some mechanical components to be mechanically deformed due to the pressure of the vibration, or some bolt connections and other mechanisms on the machine are loosened by vibration, which reduces the mechanical strength. Use efficiency, even when reaching a certain resonant frequency, make the machine exceed its own bearing capacity and cause equipment damage, which will eventually endanger the driver's life and bring us immeasurable consequences
