Detailed description of the invention
The core of the present invention is to provide a kind of traction apparatus for bogie, the traction seat of this traction apparatus for bogie is arranged in the diagonal positions of king pin component, thus reducing the draw bar extension elongation relative to king pin component, and then the installing space of reduction draw bar, improve structural compactness.
In order to make those skilled in the art be more fully understood that the present invention program, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Refer to the axonometric drawing that Fig. 3 to Fig. 6, Fig. 3 are a kind of detailed description of the invention of traction apparatus for bogie provided by the present invention, Fig. 4 is the front view of traction apparatus for bogie shown in Fig. 3, and Fig. 5 is the top view of traction apparatus for bogie shown in Fig. 3；Fig. 6 is the structural representation of king pin component in Fig. 3.
In a kind of detailed description of the invention, traction apparatus for bogie provided by the present invention includes king pin component 1 and fixes, with this king pin component 1, the mounting seat 2 being connected, specifically, through hole is offered in the middle part of mounting seat 2, the bearing pin of king pin component 1 is through this through hole, and the installing plate part of king pin component 1 is connected with the car body of the rail traffic vehicles with above-mentioned traction apparatus；The both sides of mounting seat 2 are separately installed with the first traction seat 31 and the second traction seat 32, the first traction seat 31 is provided with the first draw bar of longitudinal extension, the second traction seat 32 is provided with the second draw bar of longitudinal extension；First traction seat 31 and the second traction seat 32 are longitudinally offset from, and it is divided into the both sides of the horizontal axis of mounting seat 2, meanwhile, as shown in Figure 8, for adapting to special installing space, draw bar is arranged in " Z " font after being assembled with traction seat by rubber arthrosis.So, when arranging draw bar, draw bar is longer through the length of mounting seat 2, then to stretch out the length of mounting seat 2 shorter for draw bar, thus reducing the draw bar extension elongation relative to king pin component 1, and then the installing space of reduction draw bar, improve structural compactness.
It should be understood that when arranging the first draw bar and the second draw bar, those skilled in the art is when hope shortening draw bar is less relative to the extension elongation of mounting seat 2, it is possible to knows which direction to mounting seat 2 is installed, rather than reversely installs.
It is pointed out that described in literary composition, " transverse direction " refers to the width of bogie place rail traffic vehicles, accordingly, " longitudinal direction " refers to the traffic direction of vehicle.
Preferably, above-mentioned first traction seat 31 and the second traction seat 32 are divided into the diagonal positions of mounting seat 2, when arranging mounting rod, to being longitudinally arranged within mounting seat 2, thus reducing draw bar further to stretch out the length of mounting seat 2, further reduce the installing space of draw bar.
In above-mentioned detailed description of the invention, first traction seat 31 and the second traction seat 32 are not limited to be arranged on cornerwise position, from theory, as long as two traction seats are when correct installation draw bar, the effect reducing draw bar installation length can be played, such as two traction seats set up the both sides with installing rack in the vertical separately, and have appropriately distance.
Preferably, as shown in Figure 7, the structure of above-mentioned mounting seat 2 can be plank frame, specifically, mounting seat 2 includes upper cover plate 21 and has the lower cover 22 of preset distance with upper cover plate 21, and above-mentioned first traction seat 31 and the second traction seat 32 are installed on upper cover plate 21 and lower cover 22, and, the middle part of upper cover plate 21 and lower cover 22 can be provided with the through hole being vertically arranged, and centrepin passes through through this, to realize mounting seat 2 and the connection of king pin component 1；So, owing to mounting seat 2 is platy structure, it is cavity structure between its upper cover plate 21 and lower cover 22, then alleviates the weight of mounting seat 2, saved production cost.
It is apparent that above-mentioned mounting seat 2 is also not limited to above-mentioned plank frame, it is also possible to for other forms commonly used in the art, for instance rack and panel construction or case structure etc..
Above-mentioned first traction seat 31 and the second traction seat 32 are all welded in mounting seat 2, realizing two traction seats by the mode welded and are connected with the fixing of mounting seat 2, simplifying mounting structure, it is not necessary to separately set other connection members, thus reducing the weight of device.
In above-mentioned detailed description of the invention, when mounting seat 2 is plank frame, the first traction seat 31 and the second traction seat 32 are specifically welded in upper cover plate 21 and the side of lower cover 22.
Further, above-mentioned traction apparatus for bogie can also include the shock absorber bearing 5 being divided into mounting seat 2 both sides, two shock absorber bearings 5 are separately installed with the amortisseur 7 of horizontal expansion, shock absorber bearing 5 described in two is staggeredly arranged relative to the horizontal axis of mounting seat 2, to reduce amortisseur in the horizontal relative to the extension elongation of mounting seat 2, thus reducing the installing space of amortisseur, the structure of further compact traction apparatus.
Two shock absorber bearings 5 can be installed on mounting seat 2 by the mode welded, in order to simplifies mounting structure, reduces the weight of device further.It is apparent that shock absorber bearing 5 is also not necessarily limited to be welded in mounting seat 2, it can also be connected to mounting seat 2 by other modes conventional use of in this area, for instance bolt connection etc..
Further, above-mentioned traction apparatus for bogie also includes the horizontal backstop 6 being welded in mounting seat 2, and horizontal backstop 6 is installed on mounting seat 2 by the mode welded, thus reduce further the weight of device, simplifies apparatus structure.
It is pointed out that ordinal numbers such as " first, second " described in literary composition, be the different structure in order to distinguish same names, do not indicate that certain order, also should not be construed as any restriction.
Above a kind of traction apparatus for bogie provided by the present invention is described in detail.Principles of the invention and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to help to understand method and the core concept thereof of the present invention.It should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention, it is also possible to the present invention carries out some improvement and modification, these improve and modify in the protection domain also falling into the claims in the present invention.
