Summary of the invention
The underframe bearing-type air channel and the installation method thereof of guideway vehicle of the present invention, be to address the above problem and cancelled the air-duct apparatus of existing individual cavity, on the basis of the carrying structure that the car body underframe possesses self, adopt the splicing of sealing bonded assembly cover plate and end crossbeam to form the air channel
The objective of the invention is to, be that the air channel is formed in the main body splicing with the original carrying structure of car body underframe, do not destroy existing underframe carrying structure, do not reduce existing load-carrying capacity, guarantees the overall mechanical strength of locomotive or motor-car.
Goal of the invention also is, independent air-duct apparatus is not set, saving in material cost and mounting process, and the difficulty of processing of reduction car body underframe improves the maintainability for the air channel.
For achieving the above object, the underframe bearing-type air channel of described guideway vehicle is that the left and right carrier bar clamping by the car body both sides forms a hollow cavity.
Innovation part of the present invention is, is connected with cover plate at the upper and lower end face closure of hollow cavity, is connected with the end crossbeam at the front and back ends face closure of hollow cavity; Described cover plate is provided with ventilation inlet and the air outlet for airiness.
As above-mentioned scheme feature, connect left and right carrier bar by installing, and cover plate and end crossbeam, the hollow cavity of formation air admission and derivation promptly forms the air channel of coolant air into and out of underframe on the car body underframe.
Need not to install under the prerequisite in independent air channel, the coolant air of external environment condition enters hollow cavity from ventilation inlet, discharges from air outlet, cools off traction electric machine.
Further improvement project is, is provided with in described hollow cavity inside, hollow cavity is separated into the intermediate transverse girder of several chambers; Described intermediate transverse girder is fixedly connected between the left and right carrier bar.
The intermediate transverse girder that connects left and right carrier bar is set, can improves the load-carrying capacity of existing underframe carrying structure, and the air channel is divided into several airiness unit, increase the shunting cooling effect of coolant air.
The cover plate of each chamber is provided with air outlet.
Certainly, can be set to one by ventilation inlet, and be arranged on the cover plate of any one chamber, then on the ventilation inlet of chamber between described difference, intermediate transverse girder between the air outlet, be provided with ventilating duct for airiness.
For improving the smoothness of airiness, air outlet place on the cover board is equipped with the flange that disposes ventilating duct.
Use above-mentioned underframe bearing-type air channel structure scheme, installation method of the present invention is:
Front and rear end between the left and right carrier bar of car body underframe both sides uses the end crossbeam to seal connection respectively; Upper and lower end face between the left and right carrier bar of car body underframe both sides uses cover plate to seal connection respectively, on the cover board is provided with ventilation inlet and air outlet for airiness; At left and right carrier bar, and the hollow cavity that forms air admission and derivation between cover plate and the end crossbeam.
Between described left and right carrier bar, be fixedly connected with intermediate transverse girder, hollow cavity is separated into several chambers; The cover plate of each chamber is provided with air outlet, and on air outlet the flange that disposes ventilating duct is installed.
On the ventilation inlet of chamber between described difference, intermediate transverse girder between the air outlet, the ventilating duct for airiness is installed.
Content to sum up, the underframe bearing-type air channel and the installation method thereof of described guideway vehicle have the following advantages:
1, realizes simplifying the structure and the installation method in existing underframe air channel, having cancelled the air-duct apparatus of existing individual cavity, is that the air channel is formed in the main body splicing with original carrying structure, does not destroy existing underframe carrying structure, and can improve its load-carrying capacity, guarantee the overall mechanical strength of locomotive or motor-car.
2, independent air-duct apparatus no longer is set, can the saving in material cost, reduce the difficulty of processing of car body underframe.
3, splicing stack-mounted air channel be easy to safeguard, simple in structure, anufacturability is strong.
