Abstract

The invention discloses a semi-active-type suspended vibration isolating device for a driving cab and belongs to the technical field of automobile engineering. The device comprises an electromagnetic particle damping vibration reduction component, a suspended particle damping vibration reduction component and an elastic control damping component, wherein the electromagnetic particle damping vibration reduction component is arranged on the outer side wall of the driving cab, and the suspended particle damping vibration reduction component and the elastic control damping component are arranged between the driving cab and an automobile frame. The elastic control damping component comprises a third damping spring and a control shell. One end of the third damping spring is fixed to the automobile frame, and the other end of the third damping spring is connected with the control shell which is fixedly connected with the lower end of the suspended particle damping vibration reduction component. The lower end of the suspended particle damping vibration reduction component is further fixedly connected with an external lining of a pin bolt, and the external lining of the pin bolt is connected with a guiding rod vertically arranged at the upper end of the automobile frame. According to the semi-active-type suspended vibration isolating device, by adjusting the types and the filling rate of particle damping vibration reduction objects, driving smoothness can be met, and the device is simple in structure and low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of automobile engineering, in particular to a semi-active cab suspension vibration isolation device. Background technique [0002] During the driving process of the vehicle, the impact of the road surface is transmitted to the cab through the chassis of the car to generate vibration, which will cause discomfort and fatigue to the occupants. In order to improve the ride comfort of the vehicle and make the ride more comfortable, usually a There is a suspension device for vibration reduction, so that the cab is suspended on the frame. The existing medium-sized commercial vehicle suspension devices all adopt semi-suspension suspension. The two support points at the front of the cab are fixed connections of two sets of front suspension components using rubber vibration isolation pads. The two support points at the rear end of the cab The first support point is a floating connection of the rear suspension assembl...
