Abstract
The utility model relates to a low-rim arc tread wheel that is used for the power truck of a motor train unit, which comprises a wheel body, a wheel treading surface and a wheel rim, wherein, the wheel treading surface is of an arc shape; the thickness of the wheel rim B is 32.5 mm; the height of the wheel rim is 29 mm higher than the wheel treading surface; the wheel arc treading surface and the root part of the wheel rim are provided with a transitional curved surface with a transitional circle center coordinate RB of 13. The wheel is applied to the CA250 power truck wheel of CRH5 express motor train unit. Compared with the prior tread wheel, the wheel has the advantages that the rim grinding consumption volume is reduced, the noise between the wheel and the rail is reduced, the service life of the wheel is increased, and the wheel has absolute safety and favorable stability.
Description
Technical field
The utility model belongs to the high-speed railway passenger technology, especially relates to a kind of 200 kilometers motor train unit power truck wheels of speed per hour that are applied in to last low wheel rim arc tread wheel.
Background technology
The wheel tread of Chinese Railway passenger car bogie mainly contains two kinds of forms, adopts LM type tread form on the bogie truck of 160km/h speed class, adopts LMA type tread on the bogie truck of 200km/h speed class.Two kinds of treads are worn profile tread, dynamic performance is very poor, under the 100km/h speed conditions, LMA type tread wheel laterally bigger rocking can occur, under the 140km/h speed conditions, LMA type tread wheel rocks more serious, and noise is very big between when operation wheel track, can't satisfy the requirement of high speed railway operation requirement and comfort of passenger.
The utility model content
Technical problem to be solved in the utility model provides that a kind of wheeling edge wearing amount reduces, noise reduction, long service life between wheel track, have absolute safety and a good stationarity the EMU power truck with low wheel rim arc tread wheel, to satisfy high speed railway operation requirement, improve and take appropriate degree.
For solving the problems of the technologies described above, the utility model provides a kind of motor train unit power truck with hanging down wheel rim arc tread wheel, comprise wheel body, wheel tread and wheel rim, it is characterized in that: wheel tread is an arc, the wheel rim thickness B is 32.5mm, the wheel rim height H is higher than wheel tread baseline 29mm, and it is 13 fillet surface that wheel arc tread and wheel rim root have a transition central coordinate of circle RB.
The utility model is applied in CRH5 type EMU CA250 steering framing wheel to last, has compared following advantage with existing pattern tread wheel:
(1) the wheeling edge wearing amount reduces;
(2) noise reduces between wheel track;
(3) service life of increase wheel;
(4) adopt the vehicle of this novel tread wheel to have absolute safety and good stationarity.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, the utility model comprises wheel body 1, wheel tread 2 and wheel rim 3, wheel tread 2 is an arc, wheel rim 3 height H exceed 29mm with respect to wheel tread baseline 4, flange thickness B is 32.5mm, and the fillet surface of wheel arc tread and wheel rim root is that a transition central coordinate of circle RB is 13 circular arc.
