Abstract
The utility model discloses a locomotive axle box device, which comprises an axle box body and a triangular pull rod, wherein a through hole is formed in a vertex position of one end of the triangular pull rod, a pull rod pin passes through the through hole, the pull rod pin and the inner wall of the through hole are connected through a large rubber joint, and the upper and lower ends of the pull rod pin are respectively inserted into two installing holes. Three rubber joints are arranged on the triangular pull rod of the locomotive axle box device, the weight of the triangular pull rod is reduced, the processing is convenient, the longitudinal rigidity and the transverse rigidity are provided for a locomotive, and meanwhile, the vibration is better absorbed. The locomotive axle box device has the advantages that an axle box is easy to install and maintain, and a locomotive axle box device body can be conveniently connected with a steering frame framework, so the workload of operators can be reduced, and the work efficiency of the operators is improved.
Description
Technical field
The utility model relates to rail locomotive vehicular field, particularly a kind of locomotive axle box device.
Background technology
Traditional axlebox rod product has two rubber arthrosis, two ends at straight line, can provide good longitudinal rigidity for locomotive, and lateral stiffness is to be provided by the bending stiffness of two rubber arthrosis and the lateral stiffness of primary spring, in some cases, if locomotive needs larger lateral stiffness, need to increase the lateral stiffness of primary spring, but can make like this comfort property of locomotive decline, particularly in the vehicle of some narrow gauges, if meet the stability of vehicle operating, in the situation that guaranteeing vehicle riding comfort energy, the lateral stiffness of increase axlebox rod that just must be suitable, but the setting range of the lateral stiffness that the existing axlebox rod that has two rubber arthrosis can provide is limited, do not provide the required lateral stiffness of vehicle, at this moment the axlebox rod that has two rubber arthrosis just can not meet the performance requriements of locomotive.And in more existing patents, adopt triangular draw bar to replace straight line pull bar, on an endvertex of triangular draw bar, fixed ball pivot, ball pivot difficulty of processing is large, weight is large, and damping effect is not good, to locomotive axle box device body and being connected of truck frame bringing very large difficulty.
Summary of the invention
Technical problem to be solved in the utility model is, not enough for prior art, and a kind of locomotive axle box device is provided, and when guaranteeing that locomotive can obtain needed Longitudinal stiffness and transverse stiffness, facilitates being connected of locomotive axle box device body and truck frame.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of locomotive axle box device, comprise journal box body and triangular draw bar, described journal box body is provided with mounting groove near a side of locomotive bogie frame, respectively offers a mounting hole on the installation support plate of the upper and lower both sides of described mounting groove; On two vertex positions of drag link body one end of described triangular draw bar, be separately installed with a small rubber joint for being connected with locomotive bogie frame mount pad; On the vertex position of the described drag link body other end, offer through hole, stay rod pin is through described through hole, between described stay rod pin and described through-hole wall, by large rubber arthrosis, is connected, and insert respectively in two mounting holes at the upper and lower two ends of described stay rod pin.
On stay rod pin in described two mounting holes, cover has lining, and when stay rod pin and journal box body bump, lining can prevent that journal box body is worn and corrodes.
The mounting hole being connected with this end is stretched out in described stay rod pin lower end, and the side opening of described stay rod pin lower end sponson is provided with U-lag, in described U-lag, be provided with fixed block, described fixed block one end stretches out described U-lag and this sponson is fixedly connected with the installation support plate of described stay rod pin lower end, fixed block can prevent the downward landing of stay rod pin, increases structural strength.
Compared with prior art, the beneficial effect that the utility model has is: three rubber arthrosis has been installed on triangular draw bar of the present utility model, alleviated the weight of triangular draw bar, and easy to process, when providing Longitudinal stiffness and transverse stiffness for locomotive, absorbing vibration better; Axle box of the present utility model is easy to installation and maintenance, facilitates being connected of locomotive axle box device body and truck frame, thereby can reduce the work capacity of operating personal, has improved the work efficiency of operating personal.

The specific embodiment
As shown in Figure 1-Figure 3, the utility model one embodiment comprises journal box body and triangular draw bar, and described journal box body is provided with mounting groove 9 near a side of locomotive bogie frame, on the installation support plate 10 of described mounting groove both sides Shang Xia 9, respectively offers a mounting hole 11; On two vertex positions of drag link body 13 one end of described triangular draw bar, be separately installed with a small rubber joint 3 for being connected with locomotive bogie frame mount pad; On the vertex position of described drag link body 13 other ends, offer through hole 5, between described stay rod pin 6 and described through hole 5 inwalls, by large rubber arthrosis 2, be connected, described stay rod pin inserts respectively in two mounting holes 11 at two ends Shang Xia 6; On stay rod pin 6 in described two mounting holes 11, cover has lining 4; The mounting hole 11 being connected with this end is stretched out in described stay rod pin 6 lower ends, and the side opening of described stay rod pin 6 lower end sponsons is provided with U-lag 12, in described U-lag 12, be provided with fixed block 7, described fixed block 7 one end stretch out described U-lag 12 and this sponson is fixedly connected with by fastener 8 with the installation support plate 11 of described stay rod pin 6 lower ends.
In the present embodiment, large rubber arthrosis and two small rubber joints are all arranged on the drag link body 13 of triangular draw bar in the mode of interference fit.
During installation, first the interior fixed hub 4 of mounting hole 11 on two support plates 10, is placed on triangular draw bar two ends respectively on mounting groove 9 and truck frame mount pad 1, and two small rubber joints are fixedly connected with deflection angle framework mount pad; Then stay rod pin 6 is penetrated from the mounting hole 11 of mounting groove 9 downsides, successively through the through hole 5 on triangular draw bar and the mounting hole 11 of mounting groove 9 upsides, then U-lag 12 is inserted in fixed block 7 one end, with fastener 8, fixed block is fixed on the installation support plate 11 of stay rod pin lower end.Assembly &Disassembly is simple, convenient, fast.
