The present invention will be described below in conjunction with the accompanying drawings and with reference to specific embodiments.

Firstly, a three-braid rolling stock 100 according to the embodiment of the present invention will be described with reference to FIGS. 1-8 .

As shown in Figures 1-8, the three-braided rolling stock 100 of the embodiment of the present invention may include a first locomotive 1, a second locomotive 2, and a third locomotive 3, and the first locomotive 1 and the second locomotive 2 may be rotatable The third locomotive 3 can be rotatably connected with the second locomotive 2.

It should be noted that the three-braided rolling stock 100 can be the first locomotive 1, the second locomotive 2, and the third locomotive 3 from front to back, or it can be the first locomotive 1, the second locomotive 2, and the third locomotive from back to front. Three locomotives3.

As shown in Figures 1 and 2, a first fixed hinge 4 and a rotating hinge 5 can be arranged between the first locomotive 1 and the second locomotive 2, and the first fixed hinge 4 can make the first locomotive 1 relative to the second locomotive 2. There are three degrees of freedom, that is, the first fixed hinge 4 can make the first locomotive 1 swing laterally relative to the second locomotive 2 (that is, swing in the left and right directions in Fig. 1 and Fig. 2 ), and longitudinally nod (that is, in Fig. and in Fig. 2 in the up and down direction) and relative rotation (that is, swinging around the longitudinal centerline of the vehicle's direction of travel).

The swivel hinge 5 can make the first locomotive 1 have only one degree of freedom relative to the second locomotive 2, that is, the swivel hinge 5 can make the first locomotive 1 swing laterally relative to the second locomotive 2, but limits the relative movement of the first locomotive 1. For the longitudinal nodding and relative rotation of the second locomotive 2.

Since the first fixed hinge 4 and the rotating hinge 5 are arranged between the first locomotive 1 and the second locomotive 2, the first locomotive 1 can only swing laterally relative to the second locomotive 2, that is, the first locomotive 1 and the second locomotive 2 The degrees of freedom in this direction between the first locomotive 1 and the second locomotive 2 are completely released, while the degrees of freedom between the first locomotive 1 and the second locomotive 2 in the other two directions are restricted by the rotating hinge 5, so that the first locomotive 1 cannot be clearly relative to the second locomotive. 2 Nodding vertically and relative rotation.

As a result, the first locomotive 1 is more stable than the second locomotive 2 when the three-coil rolling stock 100 is running, and at the same time it is convenient for the three-coil rolling stock 100 to run on the curve, meeting the requirements for the three-coil rolling stock 100 to pass through curves in the horizontal direction.

It should be noted that the rotary hinge 5 cannot completely limit the longitudinal nodding and relative rotation of the first locomotive 1 relative to the second locomotive 2, that is, the first locomotive 1 can still slightly nod longitudinally and slightly rotate relative to the second locomotive 2, thus While ensuring the stability of the first locomotive 1 and the second locomotive 2, a certain degree of flexibility can still be maintained.

The first fixed hinge 4 can increase the connection strength between the first locomotive 1 and the second locomotive 2 .

The free hinge 7 can make the second locomotive 2 only have degrees of freedom in two directions relative to the third locomotive 3, that is, the free hinge 7 can make the second locomotive 2 swing laterally and nod longitudinally relative to the third locomotive 3, but limits the degree of freedom of the third locomotive 3. The relative rotation of the second locomotive 2 relative to the third locomotive 3.

Since the second fixed hinge 6 and the free hinge 7 are arranged between the second locomotive 2 and the third locomotive 3, the second locomotive 2 can swing laterally and nod longitudinally relative to the third locomotive 3, that is, the second locomotive 2 and the third locomotive The degrees of freedom between the locomotives 3 in these two directions are completely released, while the degrees of freedom in the remaining direction between the second locomotive 2 and the third locomotive 3 are restricted by the free hinge 7, so that the second locomotive 2 cannot clearly Longitudinal nodding and relative rotation with respect to the third locomotive 3 .

Therefore, the second locomotive 2 is more stable than the third locomotive 3 when the three-branch rolling stock 100 is running, and at the same time, it is convenient for the three-branch rolling stock 100 to run on the curve, satisfying the horizontal and vertical curves of the three-branch rolling stock 100 passability requirements.

It should be noted that the free hinge 7 cannot completely limit the relative rotation of the second locomotive 2 relative to the third locomotive 3, that is, the second locomotive 2 can still rotate slightly relative to the third locomotive 3, thereby ensuring that the second locomotive 2 and the third locomotive While maintaining the stability of the tri-locomotive 3, it can still maintain a certain degree of flexibility.

The second fixed hinge 6 can increase the connection strength between the second locomotive 2 and the third locomotive 3 . The second fixed hinge 6 can be located directly below the free hinge 7, and both the second fixed hinge 6 and the free hinge 7 can be located on the mid-perpendicular line between the second locomotive 2 and the third locomotive 3 in the length direction, thus facilitating the second locomotive 2 Rotate relative to the third locomotive 3.
