18-9817
The cart model 18-9817 is made according to a three-element structural scheme and is a joint development with the American company ASF Keystone and the Ukrainian industrial and investment group "InterCarGroup".
The trolley used design solutions and technologies used in the trolley Motion Control model, which is successfully operated on the railways of the United States and Canada.
AdapterPlus adapters with a polymer gasket are installed in the axle holes of the side frame, which provide passive fit of the cart in the curve and can be operated at temperatures down to -60 ° C, the use of this adapter will reduce wear on wheels and rails.
The Adapter Plus allows the wheelset to occupy a radial position when moving along a curve. The design of the elastomeric lining of the bearing adapter improves the axial alignment of the caps. Unlike conventional adapters, which are made entirely of metal, the elastomeric lining provides controlled movement of the wheelset at lower forces of entering the curve. The wheels align faster, the movement in the Curve improves, and rolling resistance decreases, the wear of the support platform of the axle hole, the support bracket and the support parts of the bearing adapter is reduced
D-5 spring set:
1.7 million car kits in operation
3% of failures during operation
7 external working springs
5 internal working springs
2 external wedge springs
2 internal wedge springs
9 spring spring set allows to use rods of smaller diameter; reduce the mass of springs; increase the resistance of the spring set by galloping oscillations;
The wedge is unloaded from the perception of excessive longitudinal and angular loads.
Approved according to the M-976 specification on HD Split Wedge and ASF Motion Control trolleys
No special side frame required
Excellent qualities of passing of curves with passive alignment.
Service life 1,000,000 miles.
Experience of operation of more than 10 000 car sets and more than 10 years of operation.
Eliminates the need to repair the axle hole due to lack of wear.
Replaces wear-resistant axle hole plates.
No bearing adapter wear.
There is no contact of metal with metal.
Increased wheel life due to reduced lateral force in the curves.
The service life of the roller bearing has been increased due to reduced lateral forces and vertical impacts.
The values of the stress-strain state of the track and turnout at all realized speeds of the test cars do not exceed the allowable and recommended. Therefore, there is no reason to limit the speed of the test cars on the track with P65 rails and turnouts of the same type on this indicator.
