Abstract
A high-speed motor train unit middle train underframe end structure is characterized in that a coupler seat, a draft sill and an underframe connection board are installed and welded to be of an integrated structure; two vertical boards are connected with the rear face of the coupler seat; the rear faces of the two vertical boards are connected with end board assemblies; the coupler seat, the two vertical boards and the end board assemblies define an overall cavity structure; the two sides of the end board assemblies are of an inward concave structure to form an electric connector installation interface; the two sides of a bottom board are welded to side apron boards; the upper surface of the bottom board is welded to the draft sill; two rectangular holes are formed in the bottom board and provide a maintenance space for end inner connectors; the ends of the whole underframe are welded to be of an overall stressed box-type structure. The whole structure is formed in a welding mode, longitudinal force borne on a train coupler is transmitted to a floor through the drift sill, the underframe connection board and the bottom board, force borne on the coupler seat is backwards transmitted through the underframe connection board and the bottom board, the front portion of the coupler seat defines a coupler box through the end board assemblies and the vertical boards to be used for installation of the coupler, the overall type stressed underframe end structure meets the intensity requirement, the welding process is simple, the product structure is achieved through a few tools, and the manufacturing period is shortened.
Description
Technical field
The present invention relates to under-carriage end construction in the middle of a kind of motor train unit, especially relate to the middle under-carriage end construction that a kind of uniform force, intensity are high, safe and reliable.
Background technology
Motor train unit underframe end, as car load vitals, is in operation and bears the transmission of hitch vertical and horizontal power, higher to requirement of strength.Existing motor train unit underframe end is all derived from CRH5 and CRH3 type motor train unit, and these two kinds of underframe ends all adopt section bar muscle to be connected the structure of power transmission with coupler seat.
At present, conventional middle under-carriage end construction is that coupler seat is connected with floor by four section bar muscle with rear side, and the longitudinal force be subject to by hitch is delivered on floor by muscle, and hitch front portion surrounds hitch chamber by plate structure, ensures the intensity of underframe end.This end construction is connected with coupler seat by four section bar muscle, and easily form rear side section bar muscle unbalance stress, local pressure is larger, especially vehicle high-speed runs, longitudinal direction of car impact shock threatens very large to Undercarriage structure, very easily form endurance crack, affect vehicle driving safety.
Summary of the invention
The object of this invention is to provide one and can realize train high-speed cruising, improve the middle under-carriage end construction of vehicle operating safety, stability under loading, weakens the impact of coupler seat longitudinal impact force on body construction.
For achieving the above object, the invention provides under-carriage end construction in the middle of a kind of EMU, it is characterized in that: coupler seat and draw beam, underframe connecting panel assembly welding is structure as a whole, two pieces of risers are connected after coupler seat, end plate composition is connected after two pieces of risers, coupler seat, two pieces of risers and end plate composition surround overall cavity structure, end plate composition both sides are concave inward structure, form electric connector mounting interface, base plate both sides are welded with sidepiece skirtboard, plate upper surface welds with draw beam, base plate has two slots, for end female connector provides space for maintenance, whole underframe end is welded into overall stressed box-structure.
Have stress hole at the front and rear of underframe connecting panel and coupler seat junction, underframe connecting panel design mix forked type structure, has stress hole at the afterbody of bifurcated.
Integral structure of the present invention is by being welded, the longitudinal force that hitch is subject to is delivered on floor by draw beam, underframe connecting panel, base plate, coupler seat is subject to power and is transmitted backward by underframe connecting panel and base plate, coupler seat is anterior surrounds coupler pocket for installing hitch by end plate composition and riser, the stressed underframe end portion structure of integral type meets requirement of strength, welding process is simple, and less frock can realize product structure, shortens the manufacturing cycle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is underframe end welding relation schematic diagram.
Detailed description of the invention
With reference to accompanying drawing 1, Fig. 2, coupler seat 8 and draw beam 10, underframe connecting panel 2 assembly welding are structure as a whole, the longitudinal beam power be subject to by coupler seat by underframe connecting panel, base plate 9 and sidepiece skirtboard is delivered to floor and side bar, two pieces of risers 4 are connected after coupler seat, end plate composition 6 is connected after two pieces of risers, coupler seat, two pieces of risers and end plate composition surrounds overall cavity structure, ensures that hitch is installed.End plate composition both sides 7 are concave inward structure, form electric connector mounting interface, base plate 9 both sides are welded with sidepiece skirtboard 5, by underframe connecting panel, the longitudinal beam power that coupler seat is subject to by base plate and sidepiece skirtboard is delivered to floor and side bar, plate upper surface welds with draw beam, base plate has two slots 11, for end female connector provides space for maintenance, stress hole 3 is had at the front and rear of underframe connecting panel and coupler seat junction, underframe connecting panel design mix forked type structure, stress hole 1 is had at the afterbody of bifurcated, whole underframe end is welded into overall stressed box-structure.
