Description

A kind of composition type draw gear of locomotive

Technical field

The present invention relates to a kind of draw gear, is a kind of composition type draw gear of locomotive specifically, belongs to the locomotive component device.

Background technology

The locomotive running gear portion of BO-BO-BO shaft type is made up of two you bogie trucks, a middle bogie.Draw gear mainly rises and transmits locomotive traction and braking force, coordinates the relative motion between bogie truck and the car body simultaneously.The domestic 6K of mainly containing locomotive, SS7, SS7B, SS7C, SS7D, Dalian locomotive works export to the narrow gauge diesel locomotive (be called for short Burma locomotive) of Burma, and mainly contain RC locomotive, GM10, Muscovite Э II10 type electric locomotive and BII85, the electric locomotive of BII86 type etc. of EF200 type locomotive, EF500 type locomotive, the Sweden of Japan abroad.The draw gear form of these locomotives mainly contains following several: be the zigzag low level digonal link of representative with 6K, SS7 series cab, this draw gear has high utilization of adhesion, bogie truck recovery performance is good, but the car body traction seat is many, drawbar height needs must adjust with tread wear, have a plurality of friction pairs in the draw gear, increased maintenance workload; With Burma's locomotive is the center pin draw gear of representative, and this draw gear structure is simpler, but utilization of adhesion is low; With the EF500 type locomotive is the low cartridge Z type pull bar of representative, and this draw gear is good to neutrality, but towing point is higher, and utilization of adhesion is lower; With Э II10, BII85, BII86 is the central push-pull type low level simplex pull rod of representative, and this draw gear is simple in structure, but utilization of adhesion is relatively low; With the EF200 type locomotive is the combined traction device of representative, promptly holding bogie truck is central push-pull type pull bar, and middle bogie adopts zigzag low level digonal link, this combined traction device utilization of adhesion height, resetting property of middle bogie is good, but middle bogie draw gear structure is complicated.Therefore, the draw gear of existing locomotive all comes with some shortcomings, and necessary this is improved.

Summary of the invention

The objective of the invention is deficiency for the draw gear that solves present locomotive, present situation at the B0-BO-BO device for tracting locomotive, a kind of novel combination type draw gear is provided, this device can make locomotive both obtain best utilization of adhesion, and draw gear does not have friction pair simultaneously, drawbar height need not be followed hollow on worn tread and be adjusted.

The objective of the invention is to be achieved through the following technical solutions: the present invention is a kind of combined traction device, the draw gear of two ends bogie truck and the draw gear of middle bogie, adopt different version respectively, the draw gear of a kind of combination truck of form, wherein, the two ends bogie truck adopts central low level push-pull type digonal link, and middle bogie adopts central push-pull type horizontal drawing bar; The two ends bogie truck comprises a flat draw bar, a triangle-pole and a diagonal draw bar.Flat draw bar one end links to each other with framework traction crossbeam by towing pin, and the other end links to each other with an angle of triangle-pole by towing pin, and an oscillating bearing is respectively adorned at flat draw bar two.One of diagonal draw bar links to each other with the car body traction seat, and the other end then links to each other with triangle-pole by towing pin, and a rubber arthrosis is respectively adorned at diagonal draw bar two, to adapt between bogie truck and the car body each to motion, provides suitable traction longitudinal rigidity simultaneously.Three angles of triangle-pole link to each other with truck end sill, flat draw bar, diagonal draw bar by towing pin respectively.Triangle-pole, flat draw bar and framework form a stable structure, and triangle-pole also works to connect flat draw bar and diagonal draw bar simultaneously.The draw gear of this kind structure can adjust end bogie truck drawbar height by adjusting the oblique angle size of the relative rail level of diagonal draw bar on a large scale, especially can obtain lower even minus drawbar height; And middle bogie adopts central push-pull type horizontal drawing bar, mainly form by a long draw bar and attaching parts, attaching parts is the elastic caoutchouc ball and socket, respectively there is an elastic caoutchouc ball and socket at long draw bar two, links to each other with framework traction crossbeam traction seat with the car body traction seat by elastic caoutchouc ball and socket Eight characters face.

Novel B O-BO-BO combined traction device is compared with existing BO-BO-BO draw gear and is had the following advantages:

Can be optimized by opposite end bogie truck, middle bogie truck drawbar height makes locomotive obtain the best degree of utilization that sticks together; Three bogie trucks all adopt central drawing pull bar, have reduced the traction seat on the car body underframe, make things convenient for the car body underframe to adopt the big girder work of central authorities simultaneously, and the transmission of exerting all one's strength is more smooth and easy, and the car body load-carrying capacity is improved; It is very little with the influence of tread wear to adopt the locomotive of this kind combined traction device to stick together degree of utilization, need not adjust the bogie truck drawbar height in the whole process of tread wear, has reduced maintenance workload and operation cost; This installs no friction pair, can effectively reduce abrasion, reduces handling labor; Make the BO-BO-BO locomotive obtain the best degree of utilization that sticks together with simple relatively structure, effectively reduce locomotive maintenance work capacity and operation cost.
