Description

Technical Field

[0001] The utility model belongs to the technical field of rail transportation, and specifically relates to a guide wheel structure capable of adjusting the distance between the guide wheel and the guide beam. Background Art

[0002] The bogie is designed based on the axle and consists of a suspension component, a drive component and a guide component. The guide component includes a guide frame, a large rotating ring bearing, a steering link and four guide wheels. The vehicle is steered by the guide force generated by the contact between the guide wheel and the guide beam.

[0003] In order to ensure the stability of vehicle operation, a gap needs to be set between the guide wheel and the guide beam to avoid constant contact between the two. The size of this gap affects the wear rate of the guide wheel and the vehicle stability index. The gap between the guide wheel and the guide beam is designed to be about 1 to 3 mm. At present, the guide assembly is fixed in position after installation. If the gap between the guide wheel and the guide beam is not at an appropriate distance, if the gap is too large, it may lead to poor ride quality. If the gap is too small, it may accelerate the wear of the guide wheel tire, and the subsequent maintenance cost is high. In addition, the gap between the guide wheel and the guide beam is at the millimeter level, which is difficult to adjust.

The bottom of the crossbeam is provided with a connecting seat through an adjusting rod on both sides, and the adjusting rod is a "C"-shaped structure and one end of the adjusting rod is inserted into the inner wall of the crossbeam. The driving mechanism includes a wheel frame and a guide wheel. The bottom end of the connecting seat is welded to the wheel frame, and the guide wheel is fixed to the wheel frame through an axis connection. The middle two sides of the wheel frame are provided with a top plate through a screw, and the top plate is in contact with the side wall of the track. The measuring mechanism includes a measuring plate and a gear. The top wall of the crossbeam is provided with a groove, and a controller is installed in the groove. The measuring plate slides on one side of the crossbeam, and a gear is installed at one end of the measuring plate, and a rotating motor is connected to one side of the gear. The device has a complex structure and cannot adjust the distance between the guide wheel and the guide beam. Utility Model Content

[0020] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0021] like Figure 1 As shown, the guide wheel structure with adjustable distance from the guide beam, the guide wheel 1 is arranged on one side of the guide beam 2, the guide wheel 1 is rotatably connected with a sleeve 4, a flange 5 is provided on the upper end of the sleeve 4, a mounting plate 3 is provided under the guide wheel 1, and the flange 5 is detachably connected to the mounting plate 3.

[0022] The mounting plate 3 is a fixed structure of the rail vehicle, the sleeve 4 is used to mount the guide wheel 1 on the mounting plate 3, the flange 5 and the mounting plate 3 are detachable, and the effect of changing the gap between the guide wheel 1 and the guide beam 2 is achieved by changing the connection position of different connecting holes 6 on the sleeve 4 and the mounting plate 3.

[0023] The flange 5 is provided with connection holes 6, which are arranged at equal intervals along the circumferential direction of the flange 5, and the center of the guide wheel 1 is located on one side of the center of the flange 5. Figure 2 As shown, the centers of the six connecting holes 6 are on the same circle, which is not concentric with the center of the guide wheel 1 or the guide wheel shaft, that is, the circle where the centers of the six connecting holes 6 are located is an eccentric circle relative to the center of the guide wheel 1. Therefore, the distances from each connecting hole 6 to the center of the guide wheel 1 are not equal. The distances between the connecting holes 6 farthest and closest to the center of the guide wheel 1 and the center of the guide wheel 1 have a certain difference, respectively. Therefore, the millimeter-level gap adjustment between the guide wheel 1 and the guide beam 2 can be adapted. Figure 2 Among them, L-2, L-1, L0, L1, L2 and L3 are the distances from the center of the six connecting holes 6 to the center of the guide wheel 1, and the length relationship is L-2<L-1<L0<L1<L2<L3.

[0024] like Figure 1 As shown, the mounting plate 3 is provided with a mounting hole 7, and the diameters of the connecting hole 6 and the mounting hole 7 are consistent. The connecting hole 6 and the mounting hole 7 are connected by bolts, and the connection between the mounting plate 3 and the sleeve 4 is achieved through the cooperation of the above two holes. There are multiple mounting holes 7, which can improve the stability of the connection with the sleeve 4.

[0025] like Figure 1As shown, the side of the flange 5 is sequentially provided with digital steel stamps, which correspond to the connection holes 6. The digital steel stamps are convenient for operators to read. Since the mounting plate 3 blocks the upper end of the flange 5, the digital steel stamps are set on the side of the flange 5. The digital steel stamps represent the hole numbers of the connection holes 6. Each connection hole 6 corresponds to a hole number, which can facilitate operators to observe the hole numbers of the connection holes 6 connected to the current mounting plate 3, and then determine the required adjustment amount, which facilitates the operator to adjust the clearance of the wheel beam. The digital steel stamps are not easy to wear, which can ensure the long-term use of the sleeve 4.

[0026] like Figure 1 As shown, the guide wheel 1 includes a guide wheel shaft, and the guide wheel shaft is located in a sleeve 4. The guide wheel shaft is designed inside the sleeve 4, and the sleeve 4 provides protection for the guide wheel shaft, which is beneficial to improving the service life of the guide wheel 1 component.

[0027] like Figure 1 As shown, the guide wheel 1 also includes two tires 9. The above structure expands the contact area between the guide wheel 1 and the guide beam 2, which is conducive to dispersing pressure, improving the horizontal stability of the vehicle, and avoiding excessive guide force between the guide wheel 1 and the guide beam 2 and causing damage.

[0028] like Figure 1 As shown, a connecting portion 8 is provided at one end of the mounting plate 3, and an arc structure is formed between the mounting plate 3 and the connecting portion 8. The connecting portion 8 is a structure for connecting the mounting plate 3 to the suspension assembly or the driving assembly, and the arc structure can disperse the local stress of the mounting plate 3 to prevent the mounting plate 3 from breaking or snapping.

[0029] like Figure 2 As shown, there are six connection holes 6. The number of the six connection holes 6 is reasonably designed to ensure that the difference L4 between adjacent connection holes 6 is at a reasonable value, and the operator can replace the adjacent connection holes 6 in sequence until the distance between the guide wheel 1 and the guide beam 2 is adjusted to a suitable distance.

[0030] like Figure 1 As shown, L4 is the distance from the center of the guide wheel 1 to the connecting hole 6 closest to the guide beam 2. According to the mounting plate 3 and the different connecting holes 6 connected thereto, the length of L4 is variable. L5 is the distance from the mounting hole 7 to the guide beam 2, and the distance is fixed. L6 is the distance from the center of the guide wheel 1 to the guide beam 2, and the length of L6 is variable. L6 is the sum of the lengths of L4 and L5, and L6 is also the sum of the lengths of L7 and the diameter of the guide wheel 1. Since the diameter of the guide wheel 1 is fixed, the distance L4 is variable. The length of L4 depends on the distance between the connecting holes 6 facing the guide beam 2 in different directions during installation and the center of the guide wheel 1. Therefore, by adjusting the length of L4, the gap L7 between the planes of the guide wheel 1 and the guide beam 2 can be adjusted.

[0031] The adjustment process is as follows: For example, if hole No. 0 faces the plane of guide beam 2 during installation, then L4 is equal to L0, which is the factory adjustment amount of guide wheel 1. Adjusting the hole facing the guide beam surface can change the gap between the wheel beams, where -2 represents the minimum gap and 3 represents the maximum gap. If the length of L4 increases, the length of L6 increases, the diameter of guide wheel 1 is fixed, and the gap L7 increases; if the length of L4 decreases, the length of L6 decreases, the diameter of guide wheel 1 is fixed, and the gap L7 decreases. As can be seen from the above, since the wheel beam gap will affect the horizontal stability of the vehicle during operation, this device can adjust the wheel beam gap within a reasonable range. If the guide wheel 1 is worn, the gap can also be reduced according to the above method.

[0032] The guide wheel structure with adjustable distance from the guide beam adopts a detachable sleeve 4 and a mounting plate 3, and a plurality of connecting holes 6 are designed on the sleeve 4. By changing the connection position of the sleeve 4 and the mounting plate 3, the effect of changing the gap between the guide wheel 1 and the guide beam 2 is achieved, which facilitates the adjustment of the gap between the wheel beam, satisfies the gap adjustment amount between the guide wheel 1 and the guide beam 2, ensures the horizontal stability of the vehicle during operation, solves the problem of difficulty in adjustment in the later stage and reduces the maintenance cost; a digital stamp corresponding to the connecting hole 6 is also designed on the sleeve 4, which facilitates the observation and gap adjustment process of the operator; the guide wheel 1 is reasonably designed, the guide wheel shaft is reliably protected, the guide component has high horizontal stability and a long service life.

[0033] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
