Description
Technical field
The present invention relates to rail traffic vehicles Draft gear of bogie, be specially a kind of multifunctional compact central pin traction device.
Background technology
Draw gear is widely used in both at home and abroad as one-above-the-other layout, and on various railway truck and Passenger Vehicle, the main connection body of draw gear and framework, transmitting tractive power and braking force, adapt to the revolution of car body relative to bogie truck.
Chinese patent CN201020135665.0 discloses the draw gear that a kind of close-coupled center key seat adds zigzag Tiebar structure, as shown in Figure 1, this structure is primarily of compositions such as center key seat seat assembling 1, horizontal damper holder 8, traction seat assembling 2, draw bar assembling 5, horizontal backstop 7, lateral dampers 6.The compact conformation of this kind of draw gear, save installing space, but this draw gear also there are the following problems:
1, draw bar Connection Block, horizontal damper holder, horizontal stopping seat are all welded on traction seat by it, and welding job amount is large, complex structure;
2, its draw bar two ends rubber arthrosis is for being arranged vertically, and in vehicular motion, the traction rubber arthrosis being connected to traction seat one end can deflect, and causes certain influence to the life-span of rubber arthrosis;
3, this draw gear is without integral lifting device.Its lateral damper and horizontal stopping seat spacing excessively near, when car body and bogie truck deflect and move, between lateral damper and horizontal backstop, very easily produce interference.
Summary of the invention
For the problems referred to above, the present invention aims to provide a kind of multifunctional compact central pin traction device, and this draw gear, based on simplified structure, enriches draw gear function, proposes novel multi-functional compact central pin traction device.It is large that this device solves traction seat welding capacity to a great extent, center key seat function singleness, easily produces the problem of interfering.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of multifunctional compact central pin traction device, comprises center key seat, the traction seat be connected with center key seat, is contained in the draw bar assembling on traction seat, and lateral damper; Its constructional feature is, key seat bottom, described center is provided with the shock absorber bearing that two double as gusset, and this shock absorber bearing is equipped with described lateral damper; Described traction seat is the semi-enclosed structure of assembling one end for holding draw bar, and the left side board of this traction seat and right side board are all equipped with horizontal backstop.
Thus, center pin holder structure is short and small compact, and installing space is little, and quality is gently changed.Horizontal damper holder is reduced to the gusset of center key seat simultaneously, while the key seat intensity of reinforcement center, trouble damper base being welded in traction seat can be removed again from, save and save cost man-hour.
Traction seat of the present invention adopts semi-enclosed body structure, and simple structure is light.Meanwhile, horizontal damper holder is arranged on the key seat of center, and attachment point position is high, and can produce interference in no instance with the parts such as traction seat, horizontal backstop, safety factor is high.
Be below the technical scheme of further improvement of the present invention:
Further, described center key seat is the single piece with center steering hole, and this key seat bottom, center is connected with traction seat by traction rubber tube.
Described center steering hole surrounding is the annular boss upwards extended, and this annular boss matches with car body end formation fixing structure.Further, the upper surface of described annular boss relative centre key seat extends upwardly to few 10mm.On center steering hole, plane exceeds plane 10mm on the key seat square of center thus, and matching with car body end forms seam effect.The upper end of center key seat is connected with car body by bolt, lower end is connected with traction seat by traction rubber tube, plays transmitting tractive power and Braking.Seam can impact by bearing load when the vehicle is running, can greatly reduce tie bolt stressed, improves bolt safe class.
For the ease of lifting, described center key seat sidewall is equipped with lifting appliance.Further, described lifting appliance comprise be contained on key seat two side, center rise revoke, be sleeved on the lifting rope revoked.Thus, draw gear of the present invention has integral lifting function concurrently.
The assembling of described draw bar comprises the draw bar arranged in zigzag, and is fitted in the traction rubber arthrosis at two ends of draw bar.Thus, draw bar is that zigzag is arranged, wherein the traction rubber arthrosis at two ends is level and presses fit in draw bar, draws rubber arthrosis and do not produce deflection in vehicular motion, has remarkable effect to the prolongation traction rubber arthrosis life-span.
Described semi-enclosed structure is fixedly linked by upper cover plate, lower cover, middle riser, left side board and right side board and is formed.Thus, draw bar one end wraps up by upper and lower cover plates, middle riser and left side plate, and protection draw bar exempts from the objectionable erosion such as dust, simultaneously side plate can also with horizontal counter stopper, restriction car body and bogie truck cross travel.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is multiple functional, structure is simple, low cost of manufacture, achieve the characteristic requirements of the longitudinal traction of bogie truck and car body, adapt to each to motion relative to bogie truck of car body, improve bogie truck dynamic performance.
Present invention, avoiding center key seat and framework, traction seat and framework, interference between lateral damper and horizontal backstop.On the key seat of center with integral lifting, functions such as lateral damper mount pad, and required installing space is little, significantly reduces productive costs.
Below in conjunction with drawings and Examples, the present invention is further elaborated.
