本考案は鉄道車両の板ばね式軸箱支持装置の支
持板に装着するダイナミツクダンパーに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dynamic damper that is attached to a support plate of a leaf spring type axle box support device for a railway vehicle.
鉄道車両、特に高速車両用台車の板ばね式軸箱
支持装置は、車輪の軸受けを収めた軸箱と台車枠
の中央寄りとを板ばねからなる支持板で連結した
ものであり、摺動摩耗部分がないこと、及び軸箱

近年多用されている。
A leaf spring type axle box support device for railway vehicles, especially high-speed vehicle bogies, connects the axle box housing the wheel bearings and the central part of the bogie frame with a support plate made of leaf springs, which prevents sliding wear. It has been widely used in recent years because it has no parts and the axle box support rigidity is hard in the front and back and relatively soft in the left and right, allowing stable support performance to be maintained.
しかし、板ばね式軸箱支持装置は摩擦部分がな
いため振動減衰能が小さく、板ばね自身の振動減
衰能も小さい。従つて、軸箱の振動に伴なつて板
ばねからなる支持板が振動し、特に支持板の共振
が280〜300Km／hr程度の走行速度で起こるため、
高速走行時になるほど応力振幅が著しく増大しこ
れが車両騒音の原因となると共に、台車の振動の
原因ともなる。 However, the leaf spring type axle box support device has a low vibration damping ability because it does not have a frictional part, and the vibration damping ability of the leaf spring itself is also low. Therefore, as the axle box vibrates, the support plate made of leaf springs vibrates, and especially resonance of the support plate occurs at running speeds of about 280 to 300 km/hr.
The stress amplitude increases significantly as the vehicle travels at higher speeds, which causes not only vehicle noise but also vibration of the bogie.
そこで、板ばね式軸箱支持装置の支持板に板ば

れている。 Therefore, by installing a vibration system other than the leaf spring vibration system on the support plate of the leaf spring type axle box support device,
Attempts have been made to dampen the leaf spring vibration system to reduce its vibration. For example, in a test report using vibration damping materials and dynamic dampers titled ``961 type prototype train axle box support plate vibration countermeasure test'' in Railway Technology Research Materials, May 1982, page 224, there are is not effective, but it is stated that a dynamic damper is effective in suppressing vibrations of the axle box support plate.

困難であつた。 However, in the conventional dynamic damper described in the above report, if the weight member etc. comes off during running, it may cause an accident such as derailment, so a U-shaped holding frame is attached to the support plate. By fixing the weight member to the inside of the frame with an elastic member, and then fixing the weight member to the support plate with bolts, the structure was such that each member could not be easily removed from the holding frame. Attachment to the box support plate was not easy and was inefficient. or,
Since the weight member and the elastic member are directly fixed, maintenance and inspection such as replacing a damaged elastic member is troublesome, and it is difficult to replace the weight member by tuning.

るものである。 Next, FIG. 3 shows the location of the dynamic damper according to the present invention. This figure shows a leaf spring type axle box support device called the one-piece Minden type.
The axle spring 1 is placed on the axle box 12 that supports the axle 13 of the
Both ends of the bogie frame 11 are supported via the bogie frame 11, and a bogie side beam 1 fixed to the center of the bogie frame 11 is further supported.
6 and the axle box 12 are supported by two upper and lower axle box support plates 1 made of leaf springs. The dynamic damper 2 is attached approximately to the center of each axle box support plate 1, and serves to significantly reduce the stress amplitude of the axle box support plate 1.
上記実施例では、ダイナミツクダンパーの各部

金具の外周面に沿つて等間隔に穴抜きした形状で
あつてもよい。 In the above embodiment, each member of the dynamic damper is cylindrical or circular, but any shape that maintains balance may be used. For example, the inner cylinder metal fitting, the elastic member, the outer cylinder metal fitting, and the weight member are formed into polygonal cylinder shapes. The seat plate and the stopper plate may be polygonal. Further, the elastic member such as rubber may be solid or may have a shape in which holes are punched at equal intervals along the outer peripheral surface of the inner cylinder fitting.
固定用ボルトの一端に形成されたストツパープ
レートのようなストツパー部は内筒金具を押えう

の大きさより大きく形成すれば、ウエイト部材等
が万一離脱した場合でも、これが固定用ボルトか
ら外れて飛び出すことを防止できる。 The stopper part, such as the stopper plate formed at one end of the fixing bolt, should be large enough to hold down the inner cylinder metal fitting, but if it is formed larger than the outer peripheral surface of the outer cylinder metal fitting, it can be used as a weight member, etc. Even if it should come off, it can be prevented from coming off the fixing bolt and jumping out.
本考案によるダイナミツクダンパーは構造が極

の装着並びに保守点検が簡単容易である。
The dynamic damper according to the present invention has an extremely simple structure, and its assembly, attachment to the axle box support plate, and maintenance and inspection are simple and easy.
また、ダイナミツクダンパーのウエイト部材は
外筒金具の外周面に圧入した構成であるから取替

チユーニングが簡単にできる利点がある。 Further, since the weight member of the dynamic damper is press-fitted into the outer peripheral surface of the outer cylindrical metal fitting, it can be replaced. Therefore, by replacing the weight member, the natural frequency of the dynamic damper can be easily matched with the natural frequency of the axle box support plate, which has the advantage that tuning of the dynamic damper can be done easily. .

安全である。 Furthermore, by making the size of the stopper plate formed at one end of the fixing bolt larger than the size of the outer cylinder metal fitting, even if the weight member etc. comes off from the inner cylinder metal fitting while the vehicle is moving, it will not come off. It is safe because the separated outer cylinder metal fittings, etc. do not come off from the fixing bolts.
