Embodiment Construction

[0065] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0066] refer to figure 1 , the rotary vibration absorber 1 can rotate around its own rotation axis, and the rotary vibration absorber 1 may include: a mass block 2 . The mass block 2 is movable, and can move close to the rotation axis and move away from the rotation axis. The rotary shock absorber 1 generates a moment of inertia in the process of rotating around the rotation axis, and the moment of inertia is used to characterize the moment of inertia of the beam. When the mass 2 is close to the rotation axis, the rotary vibration absorber 1 may have a small moment of inertia; when the mass 2 is far away from the rotation axis, the rotary vibration absorber 1 may have a large moment of inertia.

Abstract

An automobile, a rotary shock absorber, a controller for a rotary shock absorber and a control method, wherein the rotary shock absorber can rotate around its own rotation axis, comprising: a mass block, which is movably arranged and can be close to the rotation axis movement and movement away from the axis of rotation. The rotary damper includes a mass disposed movably and is capable of movement close to and away from the axis of rotation. Therefore, when the mass is close to the rotation axis, the rotary damper can have a smaller moment of inertia; when the mass is far away from the rotation axis, the rotary damper can have a larger moment of inertia. Therefore, by using the rotary damper of the technical solution, it is possible to actively adjust the rotational inertia of the rotary damper within a certain range, so as to meet the vibration damping requirements at different speeds of the transmission shaft.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile, a rotary shock absorber, a controller and a control method for the rotary shock absorber. Background technique [0002] In the field of existing automobiles, a rotary shock absorber can usually be installed on the transmission shaft, which can reduce the torsional vibration and speed fluctuation of the transmission shaft. For example, automotive engine crankshaft torsional shock absorbers, rotating mass shock absorbers, automotive dual-mass flywheels, centrifugal pendulum shock absorbers, etc. However, these rotary shock absorbers are passive shock absorbers. At different speeds of the transmission shaft, they can only maintain a damping state, and cannot adapt to different speeds of the transmission shaft. demand, resulting in lower damping efficiency. Contents of the invention [0003] The problem solved by the present invention is that the existing rotar...
