Abstract
The utility model relates to a secondary air suspension device which is characterized in that a plurality of air suspensions are communicated with an additional air chamber; a height control valve and a differential valve are communicated with the air chamber to realize the regulation of the pressure of the incoming and outgoing air and the height of the air suspensions. Bogie with heavy axle load is realized through the air suspensions which are communicated with an additional air chamber, thus meeting the demand of a vehicle when running on a small curvilinear path with high speed.
Description
Technical field
The utility model relates to a kind of later-model air spring device, is applied to a plurality of air bellow secondary suspension mechanism of rail vehicle truck specifically, belongs to mechanical manufacturing field.
Background technology
The bogie truck of guideway vehicle is a fixing right rigid frame of front and back wheel, and its secondary suspension mechanism generally adopts steel spring, single air bellow or rubber metal pad device.
Existing secondary suspension mechanism is difficult to adapt to the designing requirement of heavy, the high-speed and little curvilinear path operation of macro-axis bogie truck.If increase the load of single air bellow, its volume and take up room and can correspondingly increase, thus improve the difficulty of framework component design and configuration.
The utility model content
Secondary suspension air spring device described in the utility model, be to address the above problem and adopt a plurality of air bellows and be interconnected in the structure of an auxiliary air reservoir, its height-control valve and differential pressure valve all are communicated in this auxiliary air reservoir to realize the adjusting into and out of air pressure and air bellow height.
Design goal of the present utility model is, by the bogie truck of a plurality of air bellows that is communicated in an auxiliary air reservoir to realize that the load larger axis is heavy, and the requirement that adapts to the high-speed cruising of vehicle on little curvilinear path.
For realizing above-mentioned design goal, described secondary suspension air spring device is arranged on the both sides of rail vehicle truck respectively symmetrically.
Improvements are, are provided with the plural air bellow that is mutually permanently connected in the every side of bogie truck, are provided with the auxiliary air reservoir that is fixed in the sleeper beam above air bellow, are interconnected by auxiliary air reservoir between the air bellow.
By auxiliary air reservoir, air is switched in a plurality of air bellows, and the pressure of a plurality of air bellows is balance mutually, thus air spring device integrally the lateral pressure regulating power be improved.
Further refinement scheme is, two adjacent air bellows are fixed on the both sides, upper end of a vertical damper by bearing pin, and the below of vertical damper is fixedly connected on the bogie truck by bearing pin.
The damping in vertical direction of described secondary suspension air spring device is provided by above-mentioned vertical damper.
The below of each air bellow is provided with locating dowel pin, and locating dowel pin is plugged in the seat hole of truck frame; The air bellow admission port is arranged on the top, and is inserted in the seat hole of sleeper beam.
And the height-control valve of described secondary suspension air spring device and differential pressure valve are connected with auxiliary air reservoir respectively, and height-control valve and differential pressure valve are fixedly connected on the framework respectively.
Content to sum up, the advantage that described secondary suspension air spring device has is:
1, a plurality of air bellows are done as a wholely, regulate empty spring height and difference of pressure by cover height-control valve and a differential pressure valve, and are simple in structure, the regulating control ability is higher.
2, a plurality of air bellows that are communicated in an auxiliary air reservoir can be realized the bogie truck that the load larger axis is heavy, and the requirement that adapts to the high-speed cruising of vehicle on little curvilinear path.
