Problems solved by technology

However, the vehicle front-end opening and closing mechanism of this patent adopts multi-step operations such as translation and rotation, which has a complex structure, high failure rate, and the structure is not compact enough and it is troublesome to adjust. The mechanism connected with the hinge point needs to be modified, which is time-consuming and labor-intensive, and the cost is also high

Embodiment 1

[0026] Example 1: Reference Figure 1-Figure 3 The rail vehicle switch includes a base plate 1, a drive unit 2, a shroud mount 3, and a rotation unit 4, wherein the swivel unit 4 is arranged on the base plate 1, between the shroud mount 3 and the drive unit 2, The rotation unit 4 is connected to the wind deflector 5 through the wind deflector mount 3 , the drive unit 2 can drive the rotation unit 4 to rotate, and the rotation unit 4 drives the wind deflector 5 to move, thereby realizing the opening and closing of the wind deflector 5 .

[0027] Specifically, continue to see figure 2 The rotating unit 4 includes a first rotating shaft 411 and a second rotating shaft 412 arranged on the bottom plate 1. The rotating arm 42 is in the shape of a substantially right-angled sheet. A rotating shaft 411 rotates, and the first end of the connecting rod 43 is sleeved on the second rotating shaft 412 and can rotate around the second rotating shaft 412. One end of the connecting arm 44 i...

Embodiment 2

[0034] Embodiment 2: Different from Embodiment 1, one end of the locking device 8 is connected to the drive unit 2, and the other end of the locking device 8 is connected to the connecting rod 43 of the rotating unit 4. Specifically, the locking device 8 is connected to the drive unit 2. Can move in the chute of connecting rod 43 under driving. The driving unit 2 drives the connecting rod 43 to rotate through the locking device 8 , so as to activate the movement of the four-bar linkage mechanism to realize the opening and closing of the wind deflector 5 . After opening and closing the wind deflector 5 in place, a self-locking effect is generated between the locking device 8 and the connecting rod 43 through the dead point of the mechanism, and the shutter is locked to keep the wind deflector 5 at a predetermined position.

Embodiment 3

[0035] Embodiment 3: The difference from Embodiments 1 and 2 is that there is only one first rotating shaft 411 and one second rotating shaft 412, and the two sets of four-bar linkages share the first rotating shaft 411 and the second rotating shaft 412, That is to say, the rotating arms 41 of the two sets of four-bar linkage mechanisms are all sleeved on the first rotating shaft 411 and can rotate around the first rotating shaft 411, and the connecting rods 43 of the two sets of four-bar linkage mechanisms are all sleeved on the second rotating shaft 412 and rotate around the first rotating shaft 411. Rotatable around the second rotation axis 412 .

Abstract

The invention discloses a switch for a rail vehicle Including bottom plate, Drive unit, fairing mount, a rotating unit arranged on the bottom plate, the rotating unit is connected with the fairing through the fairing mounting seat, The driving unit can drive the rotating unit to rotate, thereby realizing the opening and closing of the fairing. The rotating unit is a four-bar linkage mechanism, andthe restriction of the narrow space is avoided by controlling the movement track of the four-bar linkage. The invention has the advantages of simple and compact structure, high stability and convenient maintenance.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle machinery manufacturing, and in particular relates to a switch for rail vehicles. Background technique [0002] As the skeleton and driving mechanism of the front-end fairing of rail vehicles, the train shutter keeps the fairing in a closed and locked state during single-row operation, forming a complete train aerodynamic shape, reducing wind resistance and wind noise, and at the same time avoiding The internal coupler and other components are affected by rain and snow; when reconnection is required, the train switch can make the shroud open and lock, so that the coupler can be completely unobstructed and can be adapted to run on different curve radii The influence of the coupler swing angle. With the increasing requirements of trains for passive energy absorption, energy-absorbing anti-climbing devices or other components are often required to be installed on both sides of the front end of ...
