Problems solved by technology

The windage braking plate can be rotated by a corresponding angle around the fixed seat. When the airflow flows to the windage braking plate, the windage braking plate will generate certain air resistance; The force is small, which improves the efficiency and saves energy; the wind resistance brake plate is symmetrically installed on the side wall panels on both sides of the motor car body, and the balance of the motor car is very good; rainwater, dust and other sundries will not fall into the wind resistance brake device and affect The function of the wind resistance brake device has a long service life; and the installation area on both sides of the motor car body is wide, so that it is convenient to install and use; but it is only one-way driving brake, and the motor car is two-way driving, it can not be well Applicable to existing motor vehicle body

Embodiment 1

[0020] Such as Figure 1 to Figure 3 A two-way wind resistance braking device for high-speed EMUs shown, including a wind resistance brake plate, a first support hinged with one end of the wind resistance brake plate through a bearing, and a second support hinged with the other end of the wind resistance brake plate through a bearing. Support; and the bearing hinged with the other end of the first support and the second support, and the plate frame installed in cooperation with the bearing; the plate frame is installed on the roof of the high-speed EMU or / and the high-speed EMU The two sides of the body; the first support and the second support are telescopic mechanisms.

[0021] Wherein, the first support and the second support may be air cylinders or hydraulic cylinders; when the plate is withdrawn, it is parallel to the vehicle body, the wind resistance brake plate of the external plate frame is parallel to the surface of the vehicle body, and the built-in plate frame The ...

Embodiment 2

[0024] Such as Figure 4 and Figure 5 As shown, the cross arrangement of the first support 2 and the second support 3 can effectively reduce the thickness of the device. When the train brakes to the left, the first support 2 installed on the plate frame 4 is filled with compressed air, and the piston rod is stretched out, pushing one side of the wind resistance brake plate 1 installed on the bearing 5 to stretch out in the wind Car body 9; when the train runs to the right, the second support 3 installed on the plate frame 4 is filled with compressed air, which can push the other side of the wind resistance brake plate 1 installed on the bearing 5 to stretch out the car in the wind Body 9.

Embodiment 3

[0026] Such as Figure 6 As shown, the first support 2 and the second support 3 are respectively arranged on different layers; when the train runs to the left and brakes, the first support 2 installed on the plate frame 4 is filled with compressed air, The piston rod is stretched out, pushing the additional plate 6 installed on the bearing 5 to rotate around the bearing 7, driving the cylinder 3, bearing 5, bearing 8 and wind resistance brake plate 1 installed on the additional plate 6, and stretching out the car body 9 together in the wind , the windage braking force is provided by the windage brake plate 1; when the train runs to the right, the second support 3 installed on the plate frame 4 is filled with compressed air, and the windage brake plate 1 mounted on the bearing 5 is pushed to rotate The bearing 8 rotates and stretches out the car body 9 in the wind, and the wind resistance braking force is also provided by the wind resistance brake plate 1 .

Abstract

The invention discloses a two-way wind resistance braking device for a high-speed motor train unit. The two-way wind resistance braking device comprises a wind resistance braking plate, a first supporting seat which is hinged to one end of the wind resistance braking plate through a bearing, a second supporting seat which is hinged to the other end of the wind resistance braking plate through another bearing, bearings which are hinged to the other end of each of the first supporting seat and the second supporting seat, and plate frames which are matched with another bearing, wherein the plate frame is externally or internally mounted on the top of the high-speed motor train unit or / and on the two sides of the high-speed motor train unit; the first supporting seat and the second supporting seat are telescopic mechanisms. The two-way wind resistance braking device for the high-speed motor train unit disclosed by the invention breaks through the traditional thinking; the wind resistance braking device which is suitable for two-way driving is creatively designed from a one-way driving brake; the two-way wind resistance braking device does not rely on a wheel-rail adhesion coefficient; when the operating speed is higher, the braking power which can be provided is higher; when the high-speed motor train unit brakes emergently, an effective auxiliary braking mode can be provided; the two-way wind resistance braking device can also serve as a standby braking mode when the high-speed motor train unit brakes commonly.

Description

technical field [0001] The invention relates to a two-way wind resistance braking device for a high-speed EMU, belonging to the technical field of train braking devices. Background technique [0002] The essence of braking is to convert the kinetic energy of the train into other forms of energy dissipation or transfer, so that the train in the high-speed running state can stop safely within the specified parking distance, so as to ensure the safety of the train operation; the commonly used railway train braking form There are mainly tread brakes, disc brakes, regenerative brakes, resistance brakes, magnetic rail brakes, eddy current brakes, energy storage brakes, etc., and the first four types of brakes are brakes that depend on the wheel-rail adhesion. Braking, tread braking and disc braking also use the brake shoe or friction plate to rub against the wheel tread. The latter three braking forms will also increase the unsprung mass of the bogie and cause a decrease in the dy...
