Abstract
The utility model provides a two point type air spring linkage of high-speed EMUs bogie, includes altitude valve, truck bloster, air spring, horizon bar, adjusting lever, motor gallows, its characterized in that: the height valves are two and are respectively installed on the same side of the two swing pillows, two safety valves are arranged on the other side of the swing pillows, one ends of the height valves and the safety valves are connected with the swing pillows, the other ends of the height valves and the safety valves are connected with the motor hanging bracket, the inner cavity of the swing pillow is an additional air chamber only for the air spring, the swing pillow is installed above the air spring, and two guide columns of the air spring are arranged in two holes in the lower plane of. The utility model discloses simple structure, low in manufacturing cost, maintenance work load are little, air consumption is few, equipment and debug time are short, can satisfy the requirement of high-speed EMUs motor car bogie operation economy.
Description
Technical field
The utility model relates to a kind of secondary suspension device of EMU bogie truck, especially relates to the LF device of the two-point form control in a kind of secondary suspension device.
Background technology
The secondary suspension device is the critical component of railway vehicle traveling portion, existing secondary suspension device adopts four-point LF device, refer to that promptly each car adjusted the height of car body floor face by four air bellows of four levelling valves control, therefore complex structure, expense height, maintenance workload is big, air consumption is big, assembling and burn in period are long, can not satisfy EMU and run the economy requirement.
The utility model content
Technical problem to be solved in the utility model provides a kind of LF device of simple in structure, maintenance workload is little, assembling and burn in period are short two-point form control, to overcome the defective that background technology exists.
For solving the problems of the technologies described above, the utility model provides a kind of two-point form LF device of EMU bogie truck, comprise levelling valve, bolster, air bellow, horizon bar, adjusting lever, the motor suspension bracket, it is characterized in that: levelling valve is two, be installed in the homonymy of two bolster respectively, the opposite side of bolster is provided with two safety valves, one end of levelling valve and safety valve links to each other with bolster, the other end links to each other with the motor suspension bracket, the bolster inner chamber is the unique auxiliary chamber of air bellow, bolster is installed in the air bellow top, and two guide pillars of air bellow place in two holes of bolster lower plane.
The utility model is simple in structure, low cost of manufacture, maintenance workload is little, consumption of air is few, assembling and burn in period short, can satisfy the requirement of EMU motor car bogie performance driving economy.

The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, the utility model comprises levelling valve 1, bolster 2, air bellow 3, safety valve 4, horizon bar 6, adjusting lever 11, motor suspension bracket 13, each car has former and later two bogie trucks, levelling valve 1 is two, be installed in the homonymy of two bolster 2 respectively, the opposite side of bolster 2 is provided with two safety valves 4, one end of levelling valve 1 and safety valve 4 is by adaptor union 7, elbow 8 links to each other with steel pipe 9, link to each other and air bellow 3 conductings with bolster 2 by adaptor union 10 again as auxiliary chamber, the other end is by horizon bar 7, adjusting lever 11, levelling valve support 12 links to each other with motor suspension bracket 13, bolster 2 inner chambers are cast with hole 15, be the unique auxiliary chamber of air bellow 3, bolster 2 is installed in air bellow 3 tops, and two guide pillars 5 of air bellow 3 place in two holes of bolster lower plane.
The safety valve effect is that safety valve plays a part to adjust height of floor from rail top when levelling valve breaks down, and guarantees that floor can guarantee within a certain height.In order to prevent vibration and to impact, guarantee traffic safety, with bolt levelling valve bearing 14 is fixed in bolster, again levelling valve is fixed on the levelling valve bearing by bolted connection.
Principle of work: the layout of bogie truck secondary suspension pneumatic equipment is made up of two air bellows, these two springs place the offside of bogie truck, each bogie truck by a levelling valve from train master air supply pipe independent gas supply, opposite side at bolster is equipped with safety valve, when levelling valve broke down, safety valve rises regulated vehicle floor face function of height.
