Below with reference to the accompanying drawings wheel end assembly 1 according to the rail vehicle of the utility model embodiment is described.

As Figure 1-Figure 5, it is pitched according to the wheel end assembly 1 of the rail vehicle of the utility model embodiment including axle housing section 100, knuckle 200, hub assembly 300, driving-shaft assembly 400.

Axle housing section fork 100 is suitable for connecting with the axle housing of the rail vehicle, and axle housing section fork 100 is equipped with section fork via hole 101. 200 section of knuckle is pivotally connected with axle housing section fork 100.Knuckle 200 is equipped with knuckle via hole 201.Knuckle 200 with it is described The horizontal wheels 2 of rail vehicle are sequentially connected.Hub assembly 300 is used to install the travelling wheel 2 of the rail vehicle.Hub assembly 300 are installed in rotation on knuckle 200.Specifically, knuckle 200 is pivotally arranged on axle housing section fork 100 and pivot Shaft axis is vertical with the length direction of the rail vehicle, and knuckle 200 is equipped with knuckle via hole 201, knuckle 200 and institute The horizontal wheels 2 for stating rail vehicle are sequentially connected.Hub assembly 300 is installed in rotation on knuckle 200, the rail vehicle Travelling wheel be mounted on hub assembly 300, the rail vehicle turn left when, horizontal wheels 2 by with the rail vehicle institute The mating band of the track girder of traveling is moved knuckle 200 and is swung, and drives hub assembly 300 and the travelling wheel together to left swing Dynamic, when the rail vehicle is turned right, horizontal wheels 2 are swung by moving knuckle 200 with the mating band of the track girder, and are driven Hub assembly 300 and the travelling wheel are swung to the right together.Driving-shaft assembly 400 includes the first sub- axis 410, the second sub- axis 420 With universal joint 430, the first sub- axis 410 passes through section fork via hole and is suitable for being driven company with the power assembly of the rail vehicle It connects, the second sub- axis 420 passes through the knuckle via hole and is suitable for being sequentially connected with hub assembly 300, the first sub- axis 410 and second Sub- axis 420 is rotatably coupled by universal joint 430.In other words, axle housing section fork 100 is sheathed on the first sub- axis 410, knuckle 200 are sheathed on the first sub- axis 410.Need exist for understanding is that " horizontal wheels 2 of knuckle 200 and the rail vehicle are driven Connection " can be to be directly connected to, or be indirectly connected with, such as realized and be sequentially connected by steering arm.

It will be appreciated by those skilled in the art that " travelling wheel is swung to the left " refers to travelling wheel in the rail vehicle On front end opposed rear end swing to the left, " travelling wheel is swung to the right " refers to that front end of the travelling wheel on the rail vehicle is opposite Rear end is swung to the right.

Below with reference to the accompanying drawings the course of work of wheel end assembly 1 according to the rail vehicle of the utility model embodiment is described.

When driving, the power assembly of the rail vehicle is total with runner hub by driving-shaft assembly 400 for the rail vehicle At 300 and travelling wheel rotation to provide power for the rail vehicle.Horizontal wheels 2 are run along on the inside of track girder, work as institute When stating track girder turning, guiding role of the horizontal wheels 2 by track girder, horizontal wheels 2 drive knuckle 200 to swing, and keep wheel hub total At 300 and the corresponding direction swing in the same direction of the travelling wheel one, while the first sub- axis 410 and the second sub- axis 420 pass through universal joint 430 rotate to corresponding direction, so that travelling wheel be enable to be adapted while rotating with the turn direction of track girder, realize The low damage function of rail vehicle.

Make knuckle by the way that knuckle 200 is arranged according to the wheel end assembly 1 of the rail vehicle of the utility model embodiment 200 are pivotably mounted on axle housing section fork 100, and hub assembly 300 and the travelling wheel are mounted on knuckle 200, The travelling wheel can be enable to swing relative to the length direction realization of the rail vehicle, so that the travelling wheel energy It is enough to be adapted with the turn direction of track girder, consequently facilitating the steering of the rail vehicle.

Simultaneously as the travelling wheel can swing relative to the rail vehicle, by making horizontal wheels 2 and turning to Section 200 transmission connection, can the rail vehicle turn when, horizontal wheels 2 can successively by bend track girder guiding Effect is gone forward side by side so as to be rotated using the cooperation of horizontal wheels 2 and track girder driving knuckle 200 relative to the rail vehicle One step drives hub assembly 300 to rotate using knuckle 200, finally drives travelling wheel to swing using hub assembly 300, compares phase Rail vehicle in the technology of pass, can be realized the self- steering function of rail vehicle, such as can make every section of the rail vehicle Isolated operation is realized in compartment, can arbitrarily increase and decrease assembling compartment in this way, convenient for improving the flexibility and variation of the rail vehicle Property, convenient for improving the adaptability of the rail vehicle, convenient for improving the use scope of the rail vehicle, it is convenient for the track The use of vehicle.

Also, since the rail vehicle can realize low damage function using wheel end assembly 1, it can reduce rail vehicle Resistance when steering can not only guarantee the rail vehicle in track girder convenient for reducing the turning radius of the rail vehicle Upper smooth traveling, and the high speed guide turning of the rail vehicle may be implemented, convenient for improving the traveling of the rail vehicle Speed improves the working performance of the rail vehicle.

In addition, the driving-shaft assembly 400 being made of setting the first sub- axis 410, the second sub- axis 420 and universal joint 430, It not only can use driving-shaft assembly 400 and the power of power assembly be transferred to the travelling wheel, to realize the rail vehicle Traveling can revolve and since the first sub- axis 410 and the second sub- axis 420 can realize universal rotational by universal joint 430 Make driving-shaft assembly 400 with the rotation of knuckle 200 while turning and be bent to corresponding direction, to make driving-shaft assembly 400 can be adapted with the rotation direction of knuckle 200, and driving-shaft assembly 400 is avoided to interfere the rotation of knuckle 200.

That is, driving-shaft assembly 400 can be rotated to corresponding direction while rotating, so as to make track The wheel end assembly 1 of vehicle realizes swinging for travelling wheel while transmitting power to travelling wheel, to realize the track The self- steering function of vehicle.

Further, via hole and the knuckle via hole are pitched by the way that the section is arranged, makes the cooperation of driving-shaft assembly 400 in institute It states in section fork via hole and the knuckle via hole, not only can be supported using section fork via hole and the knuckle via hole Driving-shaft assembly 400, the reliability after stability and installation to improve driving-shaft assembly 400, and can be in order to transmission shaft Assembly 400 and knuckle 200 synchronize swing, to keep horizontal wheels 2 more smooth to the driving of the travelling wheel.

Therefore, had according to the wheel end assembly 1 of the rail vehicle of the utility model embodiment and be conducive to steering, strong applicability etc. Advantage.

Below with reference to the accompanying drawings wheel end assembly 1 according to the rail vehicle of the utility model specific embodiment is described.

In some specific embodiments of the utility model, as Figure 1-Figure 5, according to the rail of the utility model embodiment The wheel end assembly 1 of road vehicle includes that axle housing section pitches 100, knuckle 200, hub assembly 300, driving-shaft assembly 400.

Specifically, power assembly 10 can be electronic assembly.
