Description
Technical field
The present invention relates to rail traffic vehicles Draft gear of bogie, specially a kind of multifunctional compact centrepin traction
Device.
Background technology
Traction apparatuss are widely used in both at home and abroad, on various railway freight-car and Passenger Vehicle, leading as one-above-the-other layout
The main connection body of leading-in device and framework, transmission pull strength and brake force, adapt to revolution of the car body relative to bogie.
Chinese patent CN201020135665.0 discloses the traction that a kind of close-coupled center key seat adds zigzag Tiebar structure
Device, as shown in figure 1, the structure is mainly by center key seat seat assembling 1, horizontal damper holder 8, traction seat assembling 2, draw bar group
Fill the composition such as 5, horizontal backstop 7, lateral damper 6.The compact conformation of this kind of traction apparatuss, saves installing space, but this leads
Leading-in device there is also following problem：
1st, which is welded on draw bar connecting seat, horizontal damper holder, horizontal stopping seat on traction seat, welding job amount
Greatly, complex structure；
2nd, its draw bar two ends rubber arthrosis is connected to leading for traction seat one end for being arranged vertically in vehicular motion
Draw rubber arthrosis to deflect, cause certain impact on the life-span of rubber arthrosis；
3rd, the traction apparatuss are without integral lifting device.Its lateral damper is excessively near with horizontal backstop distance between seats, car body with turn
When motion is deflected to frame, easily produce interference between lateral damper and horizontal backstop.
The content of the invention
For the problems referred to above, the present invention is intended to provide a kind of multifunctional compact central pin traction device, the traction apparatuss
Based on structure is simplified, traction apparatuss function is enriched, it is proposed that new multi-functional compact central pin traction device.The dress
Put, center key seat single function easily produces the problem interfered.
To achieve these goals, the technical solution adopted in the present invention is：
A kind of multifunctional compact central pin traction device, including center key seat, the traction seat being connected with center key seat, dress
Draw bar assembling on traction seat, and lateral damper；Which is structurally characterized in that, the center key seat bottom be provided with two and
Make the shock absorber bearing of gusset, the lateral damper is housed on the shock absorber bearing；The traction seat is for wrapping draw bar group
The semi-enclosed structure of dress one end, is respectively arranged with horizontal backstop on the left plate and right plate of the traction seat.
Thus, center pin structure is short and small compact, and installing space is little, light weight.Simultaneously horizontal damper holder is simplified
Centered on key seat gusset, fiber crops that damper base is welded in traction seat can be removed while center key seat intensity is strengthened again from
It is tired, save man-hour cost-effective.
The traction seat of the present invention adopts semi-enclosed body structure, and simple structure is light.Meanwhile, horizontal damper holder arrangement
On the key seat of center, mount point position is high, can produce interference in no instance with the part such as traction seat, horizontal backstop,
Safety coefficient is high.
It is below the technical scheme of further improvement of the present invention：
Further, the center key seat is the single piece with center steering hole, and the center key seat bottom is by traction
Rubber tube is connected with traction seat.
Center steering hole surrounding is upwardly extending annular boss, and the annular boss is engaged only to be formed with body end
Mouth structure.Further, the annular boss upwardly extends at least 10mm with respect to the upper surface of center key seat.Thus center steering
On hole, plane is higher by plane 10mm on the key seat square of center, is engaged to form seam effect with body end.Center key seat it is upper
End is connected with car body by bolt, lower end is connected with traction seat by drawing rubber tube, plays transmission pull strength and braking masterpiece
With.Seam can bear load impacting when the vehicle is running, can greatly reduce connecting bolt stress, improve bolt safe class.
For the ease of lifting, the center key seat side wall has boom hoisting.Further, the boom hoisting includes
It is mounted in rising on the key seat two side of center to revoke, has been sleeved on the lifting rope revoked.Thus, traction apparatuss of the invention have concurrently
Integral lifting function.
The draw bar assembling includes the draw bar in zigzag arrangement, and the traction rubber for being fitted in the two ends of draw bar
Glue joint.Thus, draw bar is arranged in zigzag, and the traction rubber arthrosis of both end of which are level and press fit in draw bar, car
Rubber arthrosis being drawn in traveling process and not producing deflection, there is remarkable effect to extending the traction rubber arthrosis life-span.
The semi-enclosed structure is fixedly linked and shape by upper cover plate, lower cover, middle riser, left plate and right plate
Into.Thus, draw bar one end is wrapped up by upper and lower cover plates, middle riser and left side plate, and protection draw bar exempts from dust etc.
Objectionable erosion, at the same side plate can with horizontal counter stopper, limit car body and bogie lateral displacement.
Compared with prior art, the invention has the beneficial effects as follows：Multiple functional, simple structure of the invention, low cost of manufacture,
The characteristic requirements of bogie and the longitudinal traction of car body are realized, and car body are adapted to relative to each to motion of bogie, are improved and turn
To frame dynamic performance.
Present invention, avoiding dry between center key seat and framework, traction seat and framework, lateral damper and horizontal backstop
Relate to.The functions such as the integral lifting that center key seat upper band has, lateral damper mounting seat, and required installing space is little, greatly drops
Low production cost.
Below in conjunction with drawings and Examples, the present invention is further elaborated.
