Description
Technical field
The invention belongs to vehicle body of railway vehicle design field, is related to a kind of low-floor tramcar roof end-beam arrangement.
Background technology
As Figure 1-3, the end door entablature of original shape low-floor tramcar roof end is bending part.Because low-floor has
The equipment of rail electric car is typically mounted on roof, and weight of equipment is larger；And body end portion electric interfaces and upper hinge mounting seat interface
Connection, so end door entablature needs to coordinate integral strength and rigidity when designing.The inside when end door entablature structure design
Support bar is added, termination diagonal brace has been used between being connected with side wall, is to coordinate support bar and termination diagonal brace outside end door entablature
4 stiffening plates are welded；For ease of the welding of upper hinge mounting seat, connecting plate breach is cut out in entablature end, is carried out with connecting plate
Welding.This scheme is related to part and weld seam is various, and the flatness of end door entablature top and end is extremely difficult to ensure, and connects
If welding quality is bad between plate and end door entablature, the phenomenon that seeps water can be caused.Therefore, a kind of new, convenience is worked out
The end-beam arrangement of construction has very real engineering significance.
The content of the invention
The present invention needs to solve the problems, such as to be to be directed to above-mentioned the deficiencies in the prior art, and provides a kind of low-floor tramcar
Roof end-beam arrangement.
A kind of low-floor tramcar roof end-beam arrangement, including roof end carriage, upper hinge support base, upper hinge mounting seat and end
The front end welding of wallboard, roof end carriage and roof panels, the both ends of roof end carriage and the both sides of roof panels are welded with car roof side-beam,
The upper surface of upper hinge support base and roof end carriage is hinged, and the side view of upper hinge support base is wedge shaped, and upper hinge mounting seat is ensureing to cut with scissors
It is arranged in the case that connection interface is highly constant on the front end face of upper hinge support base；The upper surface front end of roof end carriage, which is provided with, to be used for
The chimb of dash, end wall panel are riveted on below chimb on the front end face of roof end carriage, and chimb and the gap location of end wall panel upper end
Break marine glue.
Roof end carriage is by profile extrusion and is machined into.
Roof end carriage and roof panels are in the same plane.
Upper hinge support base includes being mutually perpendicular to L-shaped vertical plate and surface plate, is at least set between vertical plate and surface plate
There are two stiffener plates, stiffener plate is wedge shaped.
Compared with prior art, the beneficial effects of the present invention are：Upper hinge support base replaces the support bar of original structure, termination
Diagonal brace and stiffening plate, roof end carriage do not participate in cutting with scissors the installation of mounting seat directly.This structure is meeting car body strength and rigidity
In the case of, simplify overall structure, ensure the flatness of roof end carriage to meet the interface installation requirement of upper hinge mounting seat etc.；Car
Top girder construction on this basis, also add water-retaining structure design, and this structure has significant advantage：First, it can effectively prevent from drenching
The generation for the phenomenon that seeped water during rain, second, carrying out gluing after end wall panel riveting, technological operation is more convenient, and good appearance.
