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

Provided is an automobile, a rotary shock absorber, a controller for the rotary shock absorber and a control method. The rotary shock absorber can rotate around its own rotating shaft; the rotary shock absorber comprises a mass block which is movably arranged and can move close to the rotating shaft and move away from the rotating shaft; the rotary shock absorber comprises a movably arranged massblock which is capable of moving close to the rotating shaft and moving away from the rotating shaft. Therefore, the rotary shock absorber can have a small moment of inertia when the mass gets close to the rotating shaft; the rotary shock absorber can have a large moment of inertia when the mass gets away from the rotating shaft. Therefore, by using the rotary shock absorber of the technical solution, the rotational inertia of the rotary shock absorber can be actively adjusted within a certain range to adapt to the vibration reduction requirement of the transmission shaft at different rotational speeds.

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...
