Abstract
The utility model relates to a semi-active damping device for a railway car. The semi-active damping device is connected between a car body and a bogie structure to inhibit the transverse vibration of the car body under a low-frequency state, so chat the riding comfort of the car can be effectively improved. Two semi-active damping devices are respectively arranged along both transverse sides of the bogie structure. Each semi-active damping device is provided with a damper, a controller and an acceleration sensor. The damper is connected between the car body and the bogie structure, the controller and the acceleration sensor are directly assembled on the car body, and a cable is connected between the controller and the damper. The two semi-active damping devices which are symmetrically arranged on both longitudinal sides of the bogie structure can real-timely adjust the own damping values according to the different vibration characteristics of the car body, and in particular, aimed at the low-frequency vibration state of the car body, the semi-active damping devices can inhibit the relative yawing vibration, so the low-frequency vibration can be damped to the max.
Description
Technical field
The utility model relates to a kind of half active damping device that is applied to guideway vehicle, belongs to mechanical manufacturing field.
Background technology
The guideway vehicle that puts into operation at present, its speed per hour has generally reached more than 200 kilometers.The bogie truck of this type of hot-short mainly is to be used for to car body transmission driving and turning force and the weight of bearing its top body construction.
The car body deadweight of existing EMU is bigger, in the high-speed cruising process, require to lack between car body and the bogie truck necessary horizontal shock attenuation unit, thereby can not suppress the lateral vibration of car body and the motion of shaking the head effectively, thereby make the passenger can perceive car body generation teeter, be unfavorable for improving travelling comfort.
The utility model content
The utility model provides a kind of guideway vehicle half active damping device, its design goal is to address the above problem and is connected with half active damping device between car body and truck frame, suppress the lateral vibration of car body under the low frequency state to play, improve the ride quality of vehicle effectively.
For realizing above-mentioned design goal, described guideway vehicle half active damping device mainly has:
Along the truck frame both lateral sides, be respectively arranged with 2 half active damping devices.
Each half active damping device has 1 shock absorber, control setup and acceleration pick-up.Wherein,
Shock absorber is connected between car body and the truck frame, and control setup and acceleration pick-up are directly installed on the car body, is connected with cable between control setup and the shock absorber.
As above-mentioned basic scheme feature, couple's half active damping device in the vertical bilateral symmetry setting of framework, can come itself damping value of real-time regulated according to the different vibration characteristic of car body, suppress relative yawing at playing under the car body low frequency vibration state especially, thereby can play the attenuation of low-frequency vibration to greatest extent.
Resist the teeter of car body for further improving, can take following improvement project with respect to truck frame:
On the center pin below the connection car body, connect a car body side mount pad.In truck auxiliary transom one side, connect a framework side mount pad.
Described shock absorber is connected between car body side mount pad and the framework side mount pad.
As mentioned above, the advantage that the utility model guideway vehicle half active damping device has is to play the effect that suppresses lateral vibration effectively at the car body low-frequency vibration.When the guideway vehicle high-speed cruising, make passenger's perception less than the swing of car body, help improving its travelling comfort.
Description of drawings
Fig. 1 is the connection diagram of described half active damping device;
As shown in Figure 1, framework 1, truck auxiliary transom 11, shock absorber 2, car body side mount pad 21, framework side mount pad 22, car body 3, center pin 4.
The specific embodiment
Described half active damping device has 1 shock absorber 2, control setup and acceleration pick-up (not shown in FIG.).Wherein,
Control setup and acceleration pick-up are directly installed on the car body 3, are connected with cable between control setup and the shock absorber 2.
Described semi-active damper adopts lateral arrangement, each shock absorber 2 links to each other with control setup, as sensor, controller puts on the damping force size of car body with control according to the electromagnetic valve of this Signal Regulation semi-active damper from the acceleration signal of car body 3.
