Abstract

The utility model discloses a lifting lug of a bogie. The lifting lug comprises two lug plates, a lifting hook and a hinge pin, wherein the upper part of the lifting hook is inserted between the two lug plates through the hinge pin, the head end of the hinge pin is inserted into an opening pin for locking. The lifting lug of the bogie provided by the utility model has the beneficial effects that the overall lifting of a train unit can be realized in the condition that other equipments and tools can not be increased; the lifting hook and a lifting base on the bogie cannot be collided by controlling a gap between the top part of the lifting hook and a trolley body in the process of moving a train, the damage on the lifting hook and the base can be essentially prevented, and the service life of the lifting hook and the base can be prolonged.

Description

A kind of bogie truck hanger

Technical field

The utility model relates to 100% low floor light rail train field, particularly a kind of bogie truck hanger.

Background technology

Low floor light rail train is in a kind of extensively use abroad novel, low freight volume Rail Transit System, there are efficient and convenient, energy-conserving and environment-protective, safety and comfort, take the advantages such as path resource is few, low cost, the construction period is short, operation cost is low, be also developed rapidly at home at present.100% low floor light rail train, not establish the advantages such as exhibition booth, upper and lower passenger's convenience, travelling comfort and safety are good, has obtained more and more users' accreditation, becomes the emphasis of development.

Bogie truck is important constituent elements on 100% low floor light rail train, and the hanger on it plays a part connection body and bogie truck in the time of Integral lifting car body.How shackle structure and bogie truck unit design are combined better, the hanger that designs a kind of simple in structure, reliable operation, easy maintenance becomes the problem that must solve in bogie truck design.

Utility model content

Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of bogie truck hanger.

The technical solution adopted in the utility model is such:

A kind of bogie truck hanger, comprises two otic placodes, suspension hook and suspension hook top is through to the bearing pin between two otic placodes, the head end of bearing pin inserts spring cotter and locks.

As preferably, an inverted T shape is formed on described suspension hook bottom.

Such scheme is carried out further preferably, between described otic placode and suspension hook, separate by backing plate one.

Such scheme is carried out further preferably, between described otic placode and spring cotter, separate by backing plate two.

Such scheme is carried out further preferably, and described suspension hook top arranges one deck resilient sleeper-bearing.

In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are: can, in the situation that not increasing miscellaneous equipment and instrument, realize the Integral lifting of train unit; Owing to backing plate being installed between suspension hook and otic placode, can effectively reducing and wear and tear and reduce noise; Installed resilient sleeper-bearing additional at suspension hook top, avoided in train motion process, the collision between suspension hook and vehicle body bottom frame generation steel part, greatly reduces noise; By controlling the gap between suspension hook top and car body, make suspension hook in train motion process, not can with bogie truck on lifting pedestal bump, fundamentally avoided the damage of suspension hook and pedestal, extended their service life.

Brief description of the drawings

Fig. 1 is front view of the present utility model.

Fig. 2 is the left view of Fig. 1.

Mark in figure: 1 is vehicle body bottom frame, 2 is bearing pin, and 3 is otic placode, and 4 is that backing plate one, 5 is resilient sleeper-bearing, and 6 is that backing plate two, 7 is spring cotter, and 8 is lifting pedestal, and 9 is suspension hook.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in detail.

Most preferred embodiment:

As shown in Figure 1, a kind of bogie truck hanger, comprises two otic placodes 3, suspension hook 9 and suspension hook 9 tops is through to the bearing pin 2 between two otic placodes 3, and the head end of bearing pin 2 inserts spring cotter 7 and locks.

An inverted T shape is formed on described suspension hook 9 bottoms, as shown in Figure 2.

Between described otic placode 3 and suspension hook 9, separate by backing plate 1.In the present embodiment, the backing plate that backing plate 1 selects wear-resisting High molecular material to make, can effectively reduce and wear and tear and reduce noise;

Between described otic placode 3 and spring cotter 7, separate by backing plate 26.

Described suspension hook 9 tops arrange one deck resilient sleeper-bearing 5.This resilient sleeper-bearing 5 adopts wear-resisting, resilient High molecular material to make, and has avoided in train motion process, and the collision between suspension hook and vehicle body bottom frame generation steel part, greatly reduces noise.

In the time using the utility model, otic placode 3 and vehicle body bottom frame 1 are welded, the inverted T shape structure of suspension hook 9 bottoms, through lifting pedestal 8, can be realized to the Integral lifting of car body together with bogie truck.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
