Background art:
the rail car has a very wide application scene, and the main structure of the rail car comprises a carriage, rail wheels and a rail, wherein the rail wheels are placed on the rail and roll along the rail, the rail wheels are provided with side stoppers which are in contact with the rail in the steering or rail-changing process of the rail wheels, so that the steering or rail-changing of the rail car is realized, but the rail and the side stoppers are made of metal steel, so that the side stoppers are in direct contact with the rail and perform sliding friction when the rail car steers, the abrasion of the rail and the side stoppers is caused, and noise is generated; particularly, when the rail wheel runs at a high speed, the abrasion caused by the bounce of the rail wheel is more serious, and the generated noise is larger.
The utility model has the following contents:
the utility model discloses the technical problem that will solve is: overcome prior art's not enough, through increase gyro wheel and buffer layer on prior art's basis, change the contact mode that track and side kept off, when having solved the rail wheel and turning to, because of the rail wheel is beated and side fender and orbital contact, cause the novel railcar pulley steering wheel that wearing and tearing and noise production condition between side fender and the track take place.
The technical scheme of the utility model is that: the utility model provides a novel railcar pulley directive wheel, includes the wheel body, the wheel body includes the wheel and sets up in wheel one side and the side of structure as an organic whole with it keeps off, the side is kept off and is provided with the multistage straight flute, and the multistage straight flute is in the side keeps off and wholly is the annular, and is coaxial with it, is provided with the pivot that runs through the gyro wheel and carry out roll connection with it in the straight flute, the screw fixation is passed through in the pivot the side keeps off.
Furthermore, the number of the rollers is at least two, the rollers are embedded into roller grooves communicated with the straight grooves, and the rollers are in rolling connection with one side of the track.
Furthermore, the surface of the wheel is provided with a damping buffer layer.
The utility model has the advantages that:
1. the utility model discloses an increase gyro wheel and buffer layer on prior art's basis, change the side and keep off with orbital contact mode, when having solved the rail wheel and turning to, because of the rail wheel is beated and the side keeps off with orbital contact, cause the wearing and tearing between side fender and the track and the emergence of the noise production condition.
2. The utility model discloses keep off the side at the wheel side and set up the gyro wheel, when the railcar turned to or the derailment, the gyro wheel on the side fender can reduce the side by a wide margin and keep off and orbital frictional resistance, makes the vehicle turn to more smoothly and reduces vibrations, increases the height on the basis of current side fender height simultaneously, security when increasing high-speed the traveling.
3. The utility model discloses the wheel surface is provided with the shock attenuation buffer layer that is formed by rubber, and when the wheel rolled on the track, filtration vibrations reduced the wheel spring and further improved high-speed security.
4. The utility model discloses the side is kept off and is provided with coaxial straight flute with it, be provided with the pivot that runs through the gyro wheel and carry out roll connection with it in the straight flute, the gyro wheel embedding is in with the gyro wheel inslot of straight flute intercommunication, and carry out roll connection with track one side, realize that the gyro wheel is the annular setting on the side is kept off, and follow the side and keep off the rotation, when gyro wheel and track side contact, the gyro wheel carries out roll connection with the track under the drive that the side kept off, realize that the gyro wheel rotates along the side fender rotation direction, sliding connection before the change is roll connection, frictional force has been reduced.
5. The utility model discloses pivot and gyro wheel inlay in the recess on the side keeps off, have increased the gyro wheel and have kept off the connection stability on the side through the pivot, realize simultaneously that gyro wheel and track carry out roll connection, have solved side fender and track side direct contact and have carried out sliding friction, cause the wearing and tearing of track and side fender, the problem of noise is produced simultaneously.
Description of the drawings:
fig. 1 is a schematic structural view of a novel railway car pulley diverting wheel.
FIG. 2 is a schematic view of the structure of a straight groove and a roller groove.
Fig. 3 is a schematic structural view of the rotating shaft and the roller.
Fig. 4 is a left side view of fig. 3.
Fig. 5 is a schematic structural diagram of the working state of the novel railway vehicle pulley diverting wheel.
The specific implementation mode is as follows:
example (b): referring to fig. 1, 2, 3, 4 and 5, in the drawings, 1-side block, 2-roller, 3-wheel, 4-buffer layer, 5-rail, 6-straight groove, 7-shaft, 8-screw, 9-roller groove, 11-screw hole.
Novel railcar pulley directive wheel through on prior art's basis, increases gyro wheel 2 and increase buffer layer 4 on wheel 3 on side fender 1, changes the sliding contact between side fender 1 and the track 5 and be rolling contact, reduces frictional force between the two, when having solved wheel 3 and having turned to, because of wheel 3 beats and side keeps off 1 and track 5's sliding contact, causes wearing and tearing and the emergence of the noise production condition between side fender 1 and the track 5.
The present application is described in detail below with reference to the attached drawings and specific embodiments.
The side fender 1 sets up in one side of wheel 3 and structure as an organic whole with it, be provided with multistage straight flute 6 on the side fender 1, and multistage straight flute 6 wholly is the annular on the side fender 1, and coaxial with it, be provided with pivot 7 in the straight flute 6, pivot 7 passes through the screw 8 to be fixed on the side fender 1 (screw 8 uses with the screw 11 that sets up on the side fender 1 cooperation), the cover is equipped with gyro wheel 2 on the pivot 7, gyro wheel 2 is at least two, and imbed in the gyro wheel groove 9 with straight flute 6 intercommunication, and carry out rolling connection with track 5 one side, the wheel 3 surface is provided with the shock attenuation buffer layer 4 that forms by rubber.
During the use, wheel 3 places on track 5, shock attenuation buffer layer 4 and track 5 contact, side fender 1 is in one side of track 5, when wheel 3 rolls on track 5, side fender 1 and gyro wheel 2 also follow wheel 3 and rotate together (gyro wheel 2 is not rotatory by oneself, can understand the revolution), when the carriage turned to or the derailment under the effect of wheel 2, gyro wheel 2 and track 5 side contact on the side fender 1, because the rolling effect of wheel 3, realize that gyro wheel 2 and track 5 side are rolling connection (gyro wheel 2 follows wheel 3 and rotates together while, still rotate by oneself, can understand revolution and rotation), frictional force between having reduced.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments still fall within the scope of the technical solution of the present invention.
