Abstract
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.The utility model integral structure 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.
Description
Technical field
The utility model relates to under-carriage end construction in the middle of a kind of motor train unit, especially relates 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.
Utility model content
The purpose of this utility model is to provide one can realize train high-speed cruising, and 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 utility model 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.
The utility model integral structure 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 the utility model structural representation;
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.
