Vibration-absorbing mount for gearbox based on hydraulic mount

Abstract

The invention discloses a damp mounting frame for a gear case based on a hydraulic suspension, aiming at providing a damp mounting frame for the gear case which can not only attenuate vibrations of a low frequency zone of the gear case, but also can effectively increase the attenuation and isolation effects of vibrations in the medium and high frequency zones of the gear case. The damp mounting frame for the gear case based on the hydraulic suspension comprises an underframe, a top rack for mounting the gear case, and the hydraulic suspensions which are arranged on the underframe for supporting the top rack. Each hydraulic suspension comprises an upper chamber and a lower chamber. An interchange type tuning device is arranged between at least one pair of hydraulic suspensions. The interchange type tuning device comprises a first tuning pipeline, a floating type first self-adaptive partitioning device arranged on the first tuning pipeline, a second tuning pipeline, and a floating type second self-adaptive partitioning device arranged on the second tuning pipeline.

Description

technical field [0001] The invention relates to a vibration-damping installation frame for a gear box, in particular to a vibration-damping mounting frame for a gear box based on hydraulic suspension. Background technique [0002] The vibration and noise of the gearbox are mainly caused by the friction, vibration and collision of the transmission gear. How to effectively reduce the vibration and noise of the gearbox and make it more in line with environmental protection requirements is a key research topic at home and abroad. The vibration damping element used to support the gearbox in the traditional technology is generally a rubber-based damping element, which attenuates vibration energy through the elasticity of the rubber body and its own hysteresis loss. At present, with the advancement of technology, various damping components are used to support the gearbox to achieve better vibration damping and vibration isolation effects; among them, hydraulic mounts are currently ...

AI Technical Summary

Problems solved by technology

The hydraulic mount produces a large energy loss along the way when the liquid flows between different chambers, so that the vibration energy can be dissipated as soon as possible to achieve the purpose of damping vibration; but the current structure of the hydraulic mount is not suitable for the low frequency region Vibration can effectively reduce vibration and shock isolation, but for the vibration in the medium and high frequency region, due to the large inertia of the liquid in the flow channel between the chambers, the liquid hardly has time to flow, and it cannot be effectively used by the liquid flow. Vibration energy consumption, so it is not good for vibration isolation in the middle and high frequency areas
