Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0020] Such as figure 1 As shown, a semi-active rotary inertial damping integrated vibration damping device includes a fixed intermediate shaft (1), a synchronization device (2), a piston rod (3), a throttle valve (4), and a piston (5) , damper working chamber (6), fixed sun gear (7), movable disc (8), limit connecting rod (9), sealing piston (10), planetary gear (11), outer ring gear (12), Limiting block (13), sensor (14), ECU (15). Four planetary gears (11) are arranged around the fixed sun gear (7) and meshed with the outer ring gear (12) and the fixed sun gear (7). The inside of the planetary gear (11) is a damper working chamber (6), and the piston (5) can move up and down in the damper working chamber (6); wherein the synchronizing device (2) can rotate ...

Abstract

The invention discloses a semi-active rotary type inerter damping integrated vibration reduction device. The semi-active rotary type inerter damping integrated vibration reduction device drives a planetary gear to rotate around a fixed sun gear in a reciprocating manner through the reciprocating rotation motion of a synchronizing device and an outer gear ring so as to generate an inertial effect, so that a rotary type inerter is formed. Furthermore, the planetary gear serves as a damper working cavity, and a throttling valve on a piston generates a damping effect through axial movement of the synchronizing device. Due to the adoption of the planetary gear structure, the device has the characteristics of a compact structure, small size and light weight, and meanwhile the impact vibration resistance is high. The integration of the inerter and the damper provides a method for solving the problem of spatial arrangement and lightening a vibration reduction system. An ECU selects different transmission routes to be matched with an output shaft and change the stroke of the piston in combination with basic parameters of a system, so that two different inertial coefficients and damping coefficients are provided.

Description

technical field [0001] The invention relates to a shock absorber device, in particular to a semi-active rotary inertial damping integrated shock absorber device. Background technique [0002] Smith first proposed the concept of an inerter in 2002. An inerter is a device with two independent free ends. The force generated at both ends is proportional to its relative acceleration. This ratio is called the "coefficient of inertia" (in kg) . As a new type of mechanical device, inerters are also widely used in the field of vibration isolation. [0003] At present, most of them are translational mechanical inerters with a single structure, and there are few studies on rotary inerters. However, in the automotive transmission system, because the application of fuel consumption reduction technology leads to the increase of the torsional excitation input force and the increase of the amplitude amplification of the transmission system, the anti-resonance vibration reduction technolog...
