Description of drawings

After having read the detailed description of the present invention being made, can understand the present invention better with reference to accompanying drawing:

---Fig. 1 is the lateral plan of one embodiment of the invention,

---Fig. 2 is the planar view of this embodiment,

---Fig. 3 a to Fig. 3 c is respectively transparent view, front elevation and the lateral plan of one embodiment of the present invention.

The specific embodiment

Suspension gear as shown in Figure 1 comprises center link 3, and an end of center link 3 is fixed on the driving engine through the ball-and-socket type joint of being processed by elastic body 31, and the other end is fixed on the chassis chassis 2 through another ball-and-socket type joint 32 of being processed by elastic body.

The horizontal axis of bar 3 is vertical with the axis 1 of driving engine M, and is parallel with the axis (arrow F) of train.

Bar 3 is arranged in the horizontal surface of the plane top of engine axis 1, this horizontal surface be parallel to the train axis and through the axis A standoff distance a (for example a=125mm) of the axis 1 of driving engine.

As a kind of modification, bar 3 can be a bevelled, but its axis still remains in the perpendicular.

The direction of axis 1 (promptly along) arranged two bars in each side of bar 3 in the horizontal, and two bars have two poles 4,6 and 5,7 respectively, between two poles, forms a constant angle α.

In lateral plan (Fig. 1), part 3,4 and 5 limits a quadrangle.

Horizontal strut 4 and 5 is arranged in the horizontal surface of driving engine M axis 1 below, with axis A standoff distance b, for example equals 285mm.

As a kind of modification, pole 4 and 5 can be inclined relative to horizontal, but their axis still remains in the perpendicular.

Pole 4 and 5 is fixed on the driving engine M through ball-and-socket type joint 41 and 51 respectively, is fixed on the chassis chassis 2 through ball-and-socket type joint 42 and 52 respectively.

Non-horizontal strut 6 and 7 free end are fixed through ball-and-socket type joint 62 and 72 respectively, its center (or point of connection) preferably with the same perpendicular of being centered close to of ball-and-socket type joint 42 and 52 in.

Shown in the planar view of Fig. 2, the bar that has two poles 4,6 and 5,7 is arranged in each side of horizon bar 3, and interval g for example equals 380mm between them.

Bar 3 can be arranged in the equidistant center of bar that also can not be arranged in and have two poles 4,6 and 5,7.

In above example, the center of ball-and-socket type joint 31 and equal 390mm perpendicular to the F and the distance c of passing between the perpendicular of axis 1; Ball-and-socket type joint 41 and 51 same equal 320mm apart from e.

Being chosen as apart from d between the axis of bar 3 equals 200mm (like d between 150mm and 200mm) at the most.Preferably being chosen as apart from f between pole 4 and 5 axis equals 180mm (for example f is between 140mm and 180mm) at the most.

At last, on the one hand between ball-and-socket type joint 42 and 62 the center, the vertical distance h between ball-and-socket type joint 52 and 72 the center for example equals 200mm on the other hand.

Size under the concrete applied environment that provides hereinbefore is illustrative, can change according to the characteristic of being studied.

Bar 3, pole 4 and 5 absorb the moment of torsion of driving engine.With respect to the horizontal plane the function with pole 4,5 bevelled poles 6 and 7 is that ball-and-socket type joint 41 and 51 is not descended, and prevents that driving engine M is around axis 1 rotation.

Existing two groups of two bars (or two part 45,55-Fig. 3 a to 3c), every group of triangle that limits two poles and form a rigidity.These two groups two bars or this two parts are spaced apart and be positioned at each side (bar 3 is preferably at midway location) of bar 3 on side direction each other.Like this, two groups of two bars have the function that prevents that driving engine from rotating around train longitudinal axis (F direction).For this reason, must have and enough come fully to stop this rotation apart from g.

The ball coupling of being processed by rubber constitutes can be around the ball-and-socket type joint of three rotating shaft campaigns.Through described geometric configuration, main to having flexibility with the axis 1 parallel sideway movement of driving engine M.Strictly speaking, be in circular trace, to carry out sideway movement, but this circle diameter is enough big, if consider deviation (± 15mm), it is straight-line motion that this motion can first approximation be used as.During side travel and among the said embodiment, there is slight rotation in driving engine, and this is because from the horizontal surface upper process, the length of bar 3 and pole 4,5,6,7 are different.

The ball-and-socket type joint that can use diameter to process at the rubber of 100mm or littler (as between 70mm and 100mm).

For instance, the lateral rigidity at driving engine height place can drop to about 700N/mm, or even 600N/mm.

Among the embodiment as shown in Figure 3, ball-and-socket type joint 41,42 and 62 assembles through being generally aduncate leg-of-mutton parts 45 each other.Ball-and-socket type joint 51,52 and 72 is also assembled through same parts 55.Parts 45 substitute bar 4 and 6, and parts 55 substitute bar 5 and 7.These two groups of ball-and-socket type joints 41,42,62 and 51,52,72 spacing distance g and link together through beam 80.
