Description
Technical field
The utility model relates to a kind of relevant improvement that is directed against the guideway vehicle wheel to running gear, is adapted to the use of domestic EMU especially, belongs to mechanical manufacturing field.
Background technology
Follow the fast development with urban track traffic of significantly raising speed of domestic main line railway, the Combination property that requires the wheel of the bogie of car that running gear is taken into account lightweight, structure Strength optimization and realization high-speed operation simultaneously designs.
Existing combination to bogie truck improves and concentrates on framework, usually is and secondary suspension device aspect less to wheel running gear to be optimized.Taking turns the shortcoming that running gear is mainly embodied at present has:
1, adopts the reinforced structure form usually; Each parts all adopts comparatively complicated structure to be connected with the suspension installed device; Shortcoming is that weight is big, installation and load bearing component occupation space are bigger, is unfavorable for taking turns the lifting to running gear self light-weight design and Vehicle Speed.
2, lack improvement between the inner mounting connection structure, the maintenance of car lower component is comparatively loaded down with trivial details, and efficient is lower.
3, installation and debugging assembling work efficiency complicated, the car lower component is lower.
In view of this special present patent application that proposes.
The utility model content
The described high-speed track vehicle wheel of the utility model is to running gear; The defective that exists to prior art and take to simplify further with lightweight structure and design; Mounting structure is able to simplify between each component devices, to reach more lightweight construction and the purpose that improves whole processing efficient.
Another design goal is, takes the simplified design of connection structure between the parts, when reducing overall weight to greatest extent, improves the overhaul efficiency of car lower component.
For realizing above-mentioned design goal, described high-speed track vehicle wheel mainly includes running gear:
One axletree;
Pair of wheels is installed on the axle journal place of axletree;

Axletree is provided with 3 shaft shoulders and is beneficial to assembling wheels and gear case; This has changed, and existing axletree is elongated, the uniform architectural feature of diameter; The outstanding shaft shoulder can be realized higher relative setting accuracy, can guarantee that the bearing inner ring that press-fits rear wheel, gear case relatively rotates with shaft shoulder realization nothing respectively.
For guaranteeing the connective stability of shutoff cover of dust, the inwall of axletree end is provided with the step of annular, and the inboard of cover of dust is snapped in step, sheathed O shape circle between cover of dust and step; Back-up ring in cover of dust arranged outside one embedding axletree inboard wall groove.
O shape circle is realized the locking to cover of dust with back-up ring respectively from inside and outside both sides, and is therefore better for hollow axletree in-to-in plugging effect.While O shape circle also is easy to remove with back-up ring, does not therefore hinder cover of dust is taken off, is directed against axletree in-to-in flaw detection maintenance.
For improving the assembly precision between brake disc and the wheel, brake disc is provided with several to positioning groove, and the disc correspondence position that brake disc is installed in both sides is provided with knock hole, and locating dowel pin is set in knock hole and both sides positioning groove simultaneously.
Through improve forging working accuracy, the correspondence of assembly relation can guarantee the assembling by designing requirement realization specified angle and position of brake disc and wheel between locating dowel pin and knock hole, the positioning groove.
To the lightweight of plunging joint and the structural development of Joint strenght is that described plunging joint has the urceolus that is fixed together through bolt;
Inner at urceolus, a pair of miniature gears achieves a butt joint through bearing and outwards is connected in the drive end of gear case and drive motor respectively.
For preventing that impurity such as dust, rainwater from entering into plunging joint inside, can be provided with the protection end cap that extends to the inside at said miniature gears and between through bearing.
Optimization improvement project to gear case is that the casing top of said gear case is installed on truck frame through suspension rod.The outside of contiguous wheel is equipped with the guar plate that prevents to injure by a crashing object from the slungshot that wheel track one side splashes gear case at the casing top.
For realizing the balance and the adjusting of air pressure between the gear case internal and external environment, be provided with breather at the casing sidepiece.
For improving, can between the oil extraction bolt and lubricating plug of casing sidepiece, be provided with the oil level sight window of observing internal lubrication oil level height to the regulating power of the inner oil gas of gear case, the electrolyte level of monitors internal lubricating oil.
Content to sum up, the advantage that said high-speed track vehicle wheel has running gear is:
1, simplification of taking more to optimize and lightweight structure design help reaching more lightweight construction and the purpose that improves whole processing efficient.
When 2, reducing overall weight to greatest extent, improve the overhaul efficiency of car lower component.
3, reduce the unsprung weight of bogie truck effectively, improve the strained condition of wheel track surface, help improving Vehicle Speed.
