Problems solved by technology

[0023] (1) It is difficult to effectively isolate the low-frequency vibration during idling and the high-frequency vibration during high-speed driving in the devices with improved spring characteristics of the engine mount as shown in Patent Documents 1 and 2
[0024] (2) Moreover, in the device shown in Patent Document 3, which can selectively switch two spring constants by a switch to perform vibration damping, since the rotational speed of the engine is continuously changed from a low speed to a high speed, there is a possibility that the vibration cannot be isolated. In the area, body vibration is generated and transmitted to passengers through the floor, which hinders ride comfort

Embodiment Construction

[0104] The best mode for implementing the automobile vibration damping device of the present invention will be described with reference to the accompanying drawings. figure 1 It is a schematic diagram showing an example of a vehicle body to which the automobile vibration damping device of the present invention is mounted.

[0105] Here, the vehicle vibration damping device 10 is formed by combining an engine and a transmission, etc., with a power unit 11 that is supported on a vehicle body 13 by an engine bracket 12 for the purpose of isolating vibrations. The vibrating member 14 vibrates. Furthermore, a steering wheel 15 and a seat portion 16 are attached to the vehicle body 13 . Furthermore, the vehicle body 13 is supported by tires 18 via a suspension system 17 .

[0106] The vibrating member 14 used in this embodiment is directly fixed to the vehicle body 13 at a position different from the engine without the engine mount 12 . Furthermore, a linear actuator, a reciproc...

Abstract

An automobile vibration damping device for an automobile in which a power plant in which an engine, a transmission and the like are combined is supported by a vehicle body, including a vibrating means that generates vibration separate from vibration of the engine. Thereby, it is possible to reduce the vibration amplitude of a seat portion by the reaction force of the vibrating means. Also, if the vibration mode of the vehicle body is adjusted so as to become a node in the vicinity of the seat portion, the vibration amplitude decreases in the vicinity of the seat portion, and improves riding comfort.

Description

[0001] This application has an international application date of December 6, 2007 (date of entering the Chinese national phase: June 2, 2009), an international application number of PCT / JP2007 / 073613 (national application number: 200780044615.2), and an invention title of "minus The vibration device, the control method of the vibration damping device, the offset correction method of the vibration damping device and the leaf spring" is a divisional application. technical field [0002] The present invention relates to an automobile vibration damping device capable of reducing vibration amplitudes of a seat portion and a steering wheel portion in an engine-mounted vehicle such as an automobile to improve riding comfort. [0003] Furthermore, the present invention relates to a vibration damping device and a control method of the vibration damping device for suppressing vibration of a vibration damping target device such as an automobile. [0004] Furthermore, the present inventio...
