Description
Technical field
The utility model is related to railcar equipment technical fields.
Background technology
For the low floor vehicle using monoblock type cartridge connection draft gear, only there are one turn to for motor-car and trailer module
Frame, the factors such as uneven, the longitudinal irregularity of circuit of longitudinal load-bearing, monoblock type cartridge draft gear top in car body during due to operation
It is acted on for a long time by longitudinal alternating load, cartridge inside configuration is made fatigue crack occur and fail；Split type cartridge draft gear
Then have alternating load adaptability it is good, it is compact-sized, be active in one's movements, long lifespan, versatility are good, it is easy to maintain replace etc. it is many excellent
Point.However split type cartridge draft gear is not employed for railway low floor vehicle car body also with turning in holder connection device.
Utility model content
The purpose of this utility model is to provide a kind of split type cartridge draft gear, it effectively can enough solve longitudinal direction of car
The problem of alternating load is brought.
The purpose of this utility model solves by following technical solution：A kind of split type cartridge draft gear, including the heart
Disk seat, connecting shaft and rubber bushing；Center filler is right angle Split type structure, and the horizontal plane of left center filler is half elliptic, along right angle
Left cartridge is equipped in the middle part of horizontal line, is equipped with bolt hole along elliptical semi-circumference, the vertical plane of left center filler is equipped with and rubber bushing
The mounting base of cooperation；Right center filler horizontal plane is half elliptic, right cartridge is equipped with along right-angled horizontal line middle part, along elliptical semicircle
Week is equipped with bolt hole, and connecting shaft mounting base and the vertical plane of right center filler are arranged in a mutually vertical manner, are set on the inside of connecting shaft mounting base
There is L-shaped structure plate, the horizontal lower edge of the structural slab is equipped with drawing pull bar positioning node mounting base, and the top of connecting shaft mounting base is set
There is the groove with being connected shaft end cooperation, lower part is equipped with lateral damper mounting base.
The rubber bushing is caoutchouc elasticity wear members.
The left cartridge and right cartridge are the shoe structure erect.
Axial clearance is equipped between the connecting shaft mounting base and left center filler.
Coordinate inside the rubber bushing with connecting shaft, the external mounting base with left center filler coordinates；The connecting shaft with
Right center filler is synchronized with the movement；The rubber bushing is the double circular motion centers of circle of left and right center filler；The drawing pull bar positioning node
Mounting base is located at L-shaped structure plate lower edge on the inside of connecting shaft mounting base, for connecting single traction rod.It is indulged in low floor vehicle car body
Uneven to carrying, circuit longitudinal direction irregularity causes left and right center filler to deviate contour equilibrium state, and left and right center filler can divide
It does not move in a circle with respect to rubber bushing, left and right center filler slewing area is by connecting shaft mounting base and left center filler axial clearance
Limitation.
Further, the rubber bushing is cylindrical rubber elasticity wear members；The left side cartridge and right side
Cartridge is the shoe structure erect；The connecting shaft mounting base limits relative circumferential fortune with the axial clearance that left center filler is equipped with
Dynamic angle.
The column construction that the connecting shaft is end cylinder, both ends are flat, connecting shaft are bolted to connecting shaft installation
In the groove on seat top, on the one hand five degree of freedom of the realization limitation in addition to around own axis, are on the other hand realized and the right side
Center filler is synchronized with the movement.When cuboid connecting shaft mounting base contacts left center filler, reach maximum relative motion angle.Left,
Right center filler is uneven with longitudinal load-bearing in car body, circuit longitudinal direction irregularity and the adjustment for making opposite high and low position, avoids
The effect of long-term alternating load, improves integrally-built service life.
Compared with prior art the advantages of and effect：The utility model is related to this split type cartridge draft gear, use
For left and right split center filler instead of existing monoblock type cartridge, left and right center filler, and can be opposite by rubber bushing elastic connection
Rubber bushing moves in a circle, have alternating load adaptability is good, stability is good, it is compact-sized, be active in one's movements, be long lifespan, logical
With the advantages that property is good, replacement easy to maintain.

Specific embodiment
As shown in Figure 1, a kind of split type cartridge draft gear, including cartridge, connecting shaft 3 and rubber bushing 9.The rubber
9 inside of bushing coordinates with connecting shaft 3, and the external mounting base with left center filler 1 coordinates；The connecting shaft 3 is synchronous with right center filler 7
Movement；The drawing pull bar positioning node mounting base 6 is located at L-shaped structure plate lower edge on the inside of connecting shaft mounting base, for connecting list
Drawing pull bar；The rubber bushing 9 is the double circular motion centers of circle of left and right center filler；The connecting shaft 3 is end cylinder, both ends
Flat column construction, connecting shaft 3 are bolted in the groove on 4 top of connecting shaft mounting base, on the one hand realize that limitation removes
Five degree of freedom outside own axis, another aspect realization are synchronized with the movement with right center filler 7.
Further, the rubber bushing 9 is cylindrical rubber elasticity wear members；The left cartridge 1 and right cartridge 8 are
Shoe structure；The axial clearance of the connecting shaft mounting base 4 and left center filler 2 limits the angle of relative circular movement.
Longitudinal load-bearing is uneven in low floor vehicle car body, and circuit longitudinal direction irregularity causes left center filler 2, right center filler 7
Deviateing contour equilibrium state, left center filler 2, right center filler 7 can move in a circle with respect to rubber bushing 9 respectively, left cartridge 1,
Right cartridge 8 enables left cartridge 1 and right cartridge 8 to do small movements wherein with corresponding to slot hole loose fit on car body sleeper beam.Even
Axial clearance is left between spindle mounting base 4 and left center filler 2, left center filler 2,7 slewing area of right center filler are by this longitudinal direction
The limitation in gap, once connecting shaft mounting base 4 contacts left center filler 2, relative motion stops.Split type cartridge draft gear cooperation
Air spring uses, and can improve the stability of car body, improves monoblock type cartridge draft gear and is occurred for a long time by longitudinal alternating load
Fatigue crack and the defects of fail, have alternating load adaptability is good, stability is good, it is compact-sized, be active in one's movements, long lifespan,
The advantages that versatility is good, replacement easy to maintain.
Specific embodiment described in the utility model does not form the limitation to the application scope, every new in this practicality
Within the spirit and principle of type design, all any modification, equivalent and improvement that one of skill in the art can make etc. are equal
It should be included within the scope of protection of this utility model.
