Multi-chamber annular hydraulic torsional vibration damper

Abstract

The invention discloses a multi-liquid-chamber annular hydraulic torsional vibration damper. Vibration damping needs under the complex torsional vibration working condition of a car transmission system can be met, and the damper comprises a rubber fixed plate connected with the end of an engine crankshaft on the left side through a flange disc, a left side rubber liquid chamber connected with therubber fixed plate, a shell connected with the other end of the rubber liquid chamber, a right side rubber liquid chamber connected with the other end of the shell, and a rubber fixed plate connectedwith the other end of the right side rubber liquid chamber. The rubber fixed plate is connected with the end of an engine crankshaft on the right side through a flange disc, inertia channels are arranged between the two ends of the shell and the left and right rubber liquid chambers, two rubber films communicating with the inertia channels on the corresponding sides are arranged in the shell, multiple rubber small liquid chambers are evenly arranged in the rubber liquid chambers with the rotation axis lines as the axes, each rubber small liquid chamber communicates with the corresponding inertia channel, the rubber small liquid chambers, the inertia channels and the rubber films form multiple fluid circulation systems, and the rubber fixed plates, the rubber liquid chambers, the inertia channels and the shell share the corotational axis.

Description

technical field [0001] The invention relates to a transmission damping and damping part of an automobile, in particular to a multi-liquid chamber annular hydraulic torsional vibration damper. Background technique [0002] During the working process of the piston engine, the vibration generated by deflagration will be transmitted to the crankshaft through the piston connecting rod, causing the instantaneous angular velocity change of the crankshaft rotation, which will affect the vibration of the engine crankshaft and subsequent components connected to the crankshaft. [0003] Make it reach reasonable range for reducing vibration, existing engine is all installed torsional vibration damper at the free end of crankshaft. Generally, the existing torsional vibration dampers mostly use rubber torsional vibration dampers or silicone oil torsional vibration dampers. Such dampers can be applied to some low-power vehicle engines, and cannot be applied to vehicles such as low-speed H...

Problems solved by technology

[0004] In order to solve the problem that the existing torsional vibration damper has insufficient vibration damping performance, complex structure, high cost, and cannot meet the requirements of the complex working conditions of transmission system vibration damping, the present invention provides a multi-liquid chamber annular hydraulic torsion Vibration shock absorber, using the good vibration isolation performance and cost advantages of the hydraulic structure, combined with the hydraulic vibration damping structure, taking into account the vibration isolation of the low-frequency large amplitude and high-frequency small amplitude of the transmission system, to meet the complex torsional vibration conditions of the automobile transmission system vibration damping requirements, and can be further applied to vibration damping of drive shafts and other power transmission systems of automobiles
