Abstract
The utility model relates to a railcar chassis integral whirl tube, replacing a current separate-cavity whirl tube. Based on the original bearing structure of the car body chassis, a whirl tube is developed from sealed cover boards and end crossbeams by splicing. The whirl tube is spliced up by taking the original bearing structure of the car body chassis as the principal part, with no damage to the current bearing structure and no weakening in the bearing capacity, thus ensuring the total mechanical strength of the engine or the car. The railcar chassis integral whirl tube is characterized in that bearing beams at the left and the right sides of the car body form a hollow cavity; the lower and upper ends of the hollow cavity are sealed with cover boards and front and the back sides of the hollow cavity are sealed with end crossbeams; the cover boards are provided with an air inlet and an air outlet for air circulation.
Description
Technical field
The utility model is a kind of bearing-type air channel that is used for the car body underframe of guideway vehicle locomotive or motor-car, belongs to mechanical manufacturing field.
Background technology
The locomotive of current track vehicle or the traction electric machine of motor-car, the wheel that generally is arranged on bogie truck is to last, and blower fan then is installed on the car body.Because the convection current of adopting blower fan to produce coolant air to carry out wind cooling temperature lowering at traction electric machine and handles, therefore just need between steering framing wheel pair and car body, be provided with special air channel.
Having the structure and the cooling method that adopt now is, the air channel with independent ventilation cavity is set between blower fan and traction electric machine, and the air channel is installed in the inside of underframe.Will destroy the structure of original underframe carrier bar like this, and manufacturing process is difficult to grasp, on-site installation efficient is lower.
Independent ventiduct is installed in car body underframe inside, also is not easy to the later stage safeguard and overhaul.
The utility model content
The underframe bearing-type air channel of guideway vehicle described in the utility model, 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
Design goal of the present utility model is, is that the air channel is formed in the main body splicing with the original carrying structure of car body underframe, does not destroy existing underframe carrying structure, does not reduce existing load-carrying capacity, guarantees the overall mechanical strength of locomotive or motor-car.
Design goal 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 realizing above-mentioned design goal, 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 utility model 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.
Content to sum up, the underframe bearing-type air channel of described guideway vehicle has 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.
