Abstract
The utility model relates to a draw gear suitable for a middle-low speed maglev vehicle, which comprises a draw rod. One end of the draw rod is connected with a slipway. The other end of the draw rod is connected with a module through a traction base. The end of the draw rod, which is connected with the slipway, is higher than the end of the draw rod, which is connected with the traction base. The draw gear for the vehicle is characterized in that an included angle A of greater than 0 degree and less than 450 degrees is formed between the draw rod and the horizontal line; the end of the draw rod, which is connected with the slipway, is provided with a traction pin; and the end of the draw rod, which is connected with the traction base, is provided with an elastic rubber joint. After the draw gear is adopted, the influence of train operation impact on the sitting comfort of passengers can be reduced. The structure is simple. The weight is light. The requirement of the maglev train on the lightweight is met.
Description
Technical field
The utility model relates to the draw gear of low speed magnetic suspension vehicle in a kind of being applicable to.
Background technology
Draw gear mainly transmits train traction and braking force by draw bar, and existing draw bar has various ways according to application need.A kind of draw bar two ends are provided with the elastic caoutchouc joint, and the rubber of this inside configuration has pooling feature, are widely used in city rail railcar, EMU and electric power and diesel locomotive.But this structure is complicated, and weight is heavier.Wear-resisting pin and guide structure are directly adopted in another kind of draw bar two ends, owing to there is not elastic rubber structure, can not cushion the impact of all directions, but structure are small and exquisite, simple, and weight is lighter relatively.
For middle low speed magnetic suspension train, under the certain situation of its suspending power, light more its load-carrying capacity of conducting oneself with dignity is high relatively more.It is to alleviate own wt that important general technical of middle low speed magnetic suspension train requires as far as possible, so the draw bar structure is as far as possible simply to reduce weight.Therefore, existing middle low-speed maglev train draw bar two ends adopt simple wear-resisting pin and guide to cooperate the structure that is rigidly connected, and impact but this draw bar can not cushion train.
Summary of the invention
Technical problem to be solved in the utility model is that the defective at prior art exists provides a kind of vehicle towed device, satisfies gross vehicle body weight and structural requirement, and the available buffer longitudinal direction of car impacts
For achieving the above object, the technical solution adopted in the utility model is, a kind of vehicle towed device, comprise draw bar, draw bar one end links to each other with slide unit, and the other end links to each other with module by traction seat, be higher than and the traction seat coupling end with the slide unit coupling end, it is characterized in that described draw bar and horizon are an included angle A, and 0
0＜A＜45
0, draw bar and slide unit coupling end are provided with towing pin, are provided with the elastic caoutchouc joint with the traction seat coupling end.
Be provided with pressing plate the elastic caoutchouc joint is pressed on the traction seat, and pressing plate is fastened to traction seat by bolt.
Described towing pin, is provided with gland at towing pin and slide unit contact position, and by nut gland is compressed slide unit on draw bar by the joint ball bearing fixing.
As known from the above, the utility model is a kind of vehicle towed device, can reduce the influence of train operation impact to passenger's travelling comfort, and is simple in structure, in light weight, satisfies the magnetic-levitation train lightweight requirements.

The specific embodiment
As Figure 1-3, draw bar 6 one ends link to each other with slide unit 8, and the other end links to each other with module 1 by traction seat 2, are higher than and traction seat 2 coupling ends with slide unit 8 coupling ends, and draw bar 6 is an included angle A, 0 with horizon
0＜A＜45
0, draw bar 6 is provided with towing pin 7 with slide unit 8 coupling ends, is provided with elastic caoutchouc joint 4 with traction seat 2 coupling ends.Be provided with pressing plate 3 elastic caoutchouc joint 4 is pressed on the traction seat 2, and pressing plate 3 is fastened to traction seat 2 by bolt 5.Towing pin 7 is fixed on the draw bar 6 by joint ball bearing 9, is provided with gland 10 in towing pin 7 and slide unit 8 contact positions, and by nut 11 gland 10 is compressed slide unit 8.
