The specific embodiment
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 center pin assembly, thereby dwindle the extension elongation of draw bar with respect to the center pin assembly, and then reduce the installing space of draw bar, improve structural compactness.
In order to make those skilled in the art person understand better the present invention program, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 3 to Fig. 6, the axonometric drawing that Fig. 3 is a kind of specific embodiment of traction apparatus for bogie provided by the present invention, the front view that Fig. 4 is traction apparatus for bogie shown in Fig. 3, the birds-eye view that Fig. 5 is traction apparatus for bogie shown in Fig. 3; The structural representation that Fig. 6 is center pin assembly in Fig. 3.
In a kind of specific embodiment, traction apparatus for bogie provided by the present invention comprises center pin assembly 1 and the mount pad 2 be fixedly connected with this center pin assembly 1, particularly, mount pad 2 middle parts offer through hole, the bearing pin of center pin assembly 1 is through this through hole, and the adapter plate of center pin assembly 1 part is connected with the car body of the rail traffic vehicles with above-mentioned draw gear; The both sides of mount pad 2 are separately installed with the first draw bar that longitudinal extension is installed on the first traction seat 31 and the second traction seat 32, the first traction seats 31, and the second draw bar of longitudinal extension is installed on the second traction seat 32; The first traction seat 31 and the second traction seat 32 are staggeredly arranged in the vertical, and be divided into the both sides of the horizontal axis of mount pad 2, simultaneously, as shown in Figure 8, for adapting to special installing space, draw bar is " Z " font after assembling by rubber arthrosis and traction seat and arranges.Like this, when arranging draw bar, draw bar is longer through the length of mount pad 2, it is shorter that draw bar stretches out the length of mount pad 2, thereby dwindled the extension elongation of draw bar with respect to center pin assembly 1, and then reduced the installing space of draw bar, improved structural compactness.
Understandable, when arranging the first draw bar and the second draw bar, those skilled in the art shortens draw bar with respect to the extension elongation of mount pad 2 hour in hope, can know to which direction of mount pad 2 and install, rather than oppositely install.
It is pointed out that " laterally " described in literary composition refer to the Width of bogie truck place rail traffic vehicles, corresponding, " vertically " refers to the service direction of vehicle.
Preferably, above-mentioned the first traction seat 31 and the second traction seat 32 are divided into the diagonal positions of mount pad 2, when arranging mounting rod, to the vertical layout near mount pad 2 inside, thereby further dwindled the length that draw bar stretches out mount pad 2, further reduced the installing space of draw bar.
In the above-mentioned specific embodiment, the first traction seat 31 and the second traction seat 32 are not limited to and are arranged on cornerwise position, from theory, as long as two traction seats are when correct installation draw bar, can play the effect of dwindling the draw bar installation length gets final product, for example two traction seats set up the both sides with erecting frame in the vertical separately, and have suitable distance and get final product.
Preferably, as shown in Figure 7, the structure of above-mentioned mount pad 2 can be plank frame, particularly, mount pad 2 comprises upper cover plate 21 and has the lower cover 22 of preset distance with upper cover plate 21, and above-mentioned the 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 of vertical setting, and center pin passes through through this, to realize the connection of mount pad 2 and center pin assembly 1; Like this, because mount pad 2 is platy structures, between its upper cover plate 21 and lower cover 22, be cavity structure, alleviated the weight of mount pad 2, saved productive costs.
Apparently, above-mentioned mount pad 2 also is not limited to above-mentioned plank frame, can be also conventional other forms used in this area, such as rack and panel construction or case structure etc.
Above-mentioned the first traction seat 31 and the second traction seat 32 all are welded in mount pad 2, and the mode by welding realizes being fixedly connected with of two traction seats and mount pad 2, has simplified mounting structure, without separately establishing other links, thereby has reduced the weight of installing.
In the above-mentioned specific embodiment, when mount pad 2 is plank frame, the first traction seat 31 and the second traction seat 32 specifically are welded in the side of upper cover plate 21 and lower cover 22.
Further, above-mentioned traction apparatus for bogie can also comprise the shock absorber bearing 5 that is divided into mount pad 2 both sides, two shock absorber bearings 5 are separately installed with the bumper 7 of horizontal expansion, two described shock absorber bearings 5 are staggeredly arranged with respect to the horizontal axis of mount pad 2, in order to dwindle bumper in the horizontal with respect to the extension elongation of mount pad 2, thereby reduce the installing space of bumper, the structure of further compact draw gear.
Two shock absorber bearings 5 can be installed on mount pad 2 by the mode of welding, in order to simplify mounting structure, further reduce the weight of device.Apparently, shock absorber bearing 5 also is not limited to be welded in mount pad 2, and it also can be connected in mount pad 2 by conventional other modes of using in this area, such as the bolt connection etc.
Further, above-mentioned traction apparatus for bogie also comprises the horizontal backstop 6 that is welded in mount pad 2, and laterally backstop 6 is installed on mount pad 2 by the mode of welding, thereby has further reduced the weight of device, has simplified apparatus structure.
It is pointed out that ordinal numbers such as " first, second " described in literary composition, is in order to distinguish the different structure of same names, does not mean 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.Applied specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present invention and core concept thereof.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of the claims in the present invention.
