Description
Technical field
The present invention be directed to the draw beam structure that is applied to guideway vehicle and the improvement of welding manner, belong to mechanical manufacturing field.
Background technology
Universal and popularization rapidly along with present domestic city track traffic has proposed higher design and use requirement for the draw beam that consists of the drive system major part.
As the draw beam that is applied to light rail train, subway is the central module that connects and transmit to car body the bogie truck propulsive effort, is also to realize vehicle fast and the power transmission key equipment of safety traffic.Existing draw beam adopts the carbon steel welded structure at large, because consider that the corrosion of carbon steel need to reserve enough corrosion allowance to carbon steel sheet, thereby increased the weight of draw beam self, but also increased the weight of draw beam self from the another side, be unfavorable for light-weighted car body design and improve train running speed.
And the stress after sleeper beam, the side bar of draw beam and car body below is connected is comparatively concentrated, thereby is easy to cause draw beam stress to concentrate and the probability of increase stress damage shortens the service life of draw beam significantly.
In addition, also exist draw beam and hitch the challenge that is connected is installed, be unfavorable for carrying out paint spraying and having reduced the antiseptic operability of draw beam from draw beam inside.
In view of this, the special present patent application that proposes.
Summary of the invention
