Abstract
The utility model relates to a steering frame central traction device without an abrasion structure, which is mainly composed of a center pin, a traction beam, traction pull rods and a center pin sleeve. The center pin sleeve is arranged in a center cylinder of the traction beam in a pressing manner, the center pin is assembled with the center pin sleeve in a concentric manner, the center pin is matched with the center pin sleeve by a wimble, the traction pull rods are arranged at the two sides (left and right) of the center cylinder of the traction beam, and the traction pull rods and the traction beam are vertically installed to form a Z-shaped structure along the length direction. The central traction device is characterized in that the center pin sleeve adopts a vulcanization structure of metal and rubber, and the center pin adopts a hollow casting structure. The advantages of the central traction device are as follows: the performance of the center pin sleeve adopting the rubber vulcanization structure is more stable than that of a composite spring, the creep deformation of the rubber in the center pin sleeve is limited by the metal at the inner and outer layers, the creep deformation of the rubber vulcanization structure is less than that of the composite spring, and impact on the final performance of the central traction device is weak. Moreover, as the hollow casting structure of the center pin is more reasonable than the original structure of the center pin, not only the fatigue intensity is improved, but also the weight is reduced.
Description
Technical field
The utility model relates to a kind of central draw gear of configuration in railroad truck, the bogie truck central authorities draw gear that particularly a kind of intensity allowance is big, performance is subjected to the little nothing abrasion structure of rubber draw.
Background technology
On the subway car bogie truck at home and abroad, central draw gear adopts " Z " type Tiebar structure mostly, but elasticity bonded assembly structure has nothing in common with each other on the car and between the bogie truck, and the structure of center pin also has nothing in common with each other.At present domestic what generally adopt is the complex spring structure, and center pin adopts solid column construction.The central draw gear performance of complex spring structure is subjected to the influence of complex spring rubber creep very big, can cause cisco unity malfunction when serious.Want running check and maintenance in the use, to guarantee its performance, the center pin of solid column construction is not only from great, and the intensity allowance is not high, the strength at repeated alternation deficiency.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of bogie truck central authorities draw gear that does not have the abrasion structure, overcomes the rubber creep to its Effect on Performance, reduces the maintenance requirement of central draw gear as far as possible.Improve simultaneously the intensity allowance of each parts as much as possible, guarantee the safety of whole central draw gear.
For solving the problems of the technologies described above, the utility model provides a kind of bogie truck central authorities draw gear that does not have the abrasion structure, mainly by center pin, draw beam, drawing pull bar, the center guide is formed, the center pin cover is fitted in the central tube of draw beam, center pin and center guide concentric fits, adopt awl to cooperate between the two, drawing pull bar is installed in the left and right sides of draw beam central tube, the length direction of drawing pull bar is installed with the length direction of draw beam is vertical, form " Z " font structure, it is characterized in that: the center guide adopts the sulfuration structure of metal and rubber, and center pin adopts the cast structure of hollow.
Advantage of the present utility model: the center guide of vulcanization of rubber structure is more stable than the performance of complex spring, and the creep of rubber is subjected to the restriction of ectonexine metallo-in the guide of center, and creep compliance is littler than complex spring, and is also little to the final Effect on Performance of central draw gear.The hollow cast structure of center pin is also more reasonable than the structure of former center pin, has not only improved its strength at repeated alternation and has also reduced weight.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, part 1 is a draw beam, and part 2 is the center guide, and part 3 is a center pin, and part 4 is a drawing pull bar.Wherein, the center guide is the core of this device.The center guide makes outer field metal of center guide and draw beam relative fixed by press-fiting in the endoporus that is fixed on draw beam.Be cone match between center guide inner layer metal and the center pin, the two is fixed together by other annex.Between the inside and outside layer of center guide metal, rubber is arranged, not only inside and outside layer metal connected together, can also allow the two relative motion within the specific limits, satisfy between center pin and the draw beam not only relative fixed but also have the requirement of relative motion to a certain degree.Drawing pull bar connects together by annex and draw beam, forms " Z " font structure, and the two ends of stretching out are connected on the truck frame.Link to each other by annexes such as bolts between the last plane of center pin and the car body.Like this, both guaranteed the relative position between car body and the bogie truck, the requirement of relative motion between car body and the bogie truck when having satisfied vehicle operating again.
