Quiet, dynamic loading passes it on rail, and gives rolling stock each parts the load transmission generated by guideway irregularity.This
Outside, the driving and braking of rolling stock are also by wheel to working.Stacking pressure to axle and wheel and press fitting process
There is a strict demand, distance between backs of wheel flanges is from must assure that within the scope of 1353 ± 3 millimeters.To ensure that rolling stock operation is flat
Surely, wheel-rail interaction power and running resistance, the processing ovality and the degree of eccentricity and axis of axle journal and wheel tread are reduced
Cervical vertebra degree all must not exceed prescribed limit, and wheel need to replace it, to being easily damaged using process when single vehicle at present
Wheel is generally required to take turns when being damaged and be replaced to whole, greatly improves use cost.
Invention content：
The purpose of the present invention is that solve the above-mentioned problems and provides a kind of locomotive driving wheel wheel pair, solves the prior art
There are the problem of.
To solve the above-mentioned problems, the present invention provides a kind of technical solutions：
A kind of locomotive driving wheel wheel pair, including main axle, the main axle include the first wheel shaft and the second wheel shaft, and described first
Wheel is both passed through at wheel shaft and second axle ends, and first wheel shaft is lived with second wheel shaft and the wheel
It is dynamic to connect, the grafting key having a style of one's own with it is equipped at first axle ends, second axle ends offer limit
Card slot, the grafting key are correspondingly arranged with the limit card slot, and first wheel shaft passes through the grafting key and the limit
Card slot and second wheel shaft fix clamping, offer spliced eye on the grafting key, and described the of the limit card slot both sides
Through-hole is offered on great wheel arbor, and the spliced eye is correspondingly arranged with the through-hole.
Preferably, spacer pin is embedded on second wheel shaft, and the spacer pin extends to institute across the through-hole
It states in spliced eye.
Preferably, the first wheel shaft make-up is close to be nested with locking axle sleeve, it is embedded with locking member on the locking axle sleeve,
And the locking member is closely pressed across the locking axle sleeve with first wheel shaft upper surface.
Preferably, first wheel shaft is installed with end with second axle ends across the wheel
Lid.
Preferably, being detachable connection between first wheel shaft and second wheel shaft.
Beneficial effects of the present invention：
Structure of the invention is compact, easy to use, when the internal single wheel of wheel, which is damaged, to be needed to replace it, only needs
The wheel of damage is replaced, without wheel is needed to change to entirety, use cost is effectively reduced, has saved resource, meet reality
A variety of use demands in the case of border, wheel dismantle flexibly integral installation, have higher practicability, with good economic efficiency
And social benefit, suitable for promoting the use of.
Description of the drawings：
The present invention is described in detail by following specific implementations and attached drawing for ease of explanation,.
Fig. 1 is the structure chart of the present invention；
Fig. 2 is the main axle structure chart of the present invention.
In figure；1, main axle, 2, wheel, 3, end cap, 4, locking axle sleeve, 5, locking member, 6, spacer pin, the 7, first wheel shaft,
8, grafting key, 9, spliced eye, the 10, second wheel shaft, 11, limit card slot, 12, through-hole.
Specific implementation mode：
