Description
Technical field
The present invention relates to a kind of retaining mechanisms to use more particularly, to a kind of locking device suitable for gauge-changeable bogie
The locking of slipping mechanism and bogie axle case apparatus before and after becoming rail.
Background technology
Since countries in the world use different gauge standards, such as the railway of China is standard gauge, and gauge is
1435mm, Russian and most of Eastern Europe, country of Central Asia railway be broad gauge, gauge 1520mm, also some country
Gauge standard is narrow gauge 1000mm, and therefore, rail truck is transported to be led directly on standard gauge lines and width, narrow gauge
Row, then need to realize by gauge-changeable bogie.
Gauge-changeable bogie is a kind of unconventional bogie, and the main distinction of it and conventional bogie is to take turns to knot
Structure, wheel are the key that realize gauge changing function to structure design, and gauge-changeable bogie wheel pair is with conventional steering framing wheel to structure
It compares, needs to increase by a sleeve locking apparatus, the effect of locking device is unlock and running locking before realizing wheelslip
It is fixed, it is to directly affect the critical component that can smoothly realize distance between backs of wheel flanges variation and ensure train operating safety, locking dress
The unlock set and locking action need to be automatically performed in the case where ground unlocks locking beam action；Become rail process generally to be not more than
The speed of 15km/h (usual 7km/h) realizes change rail by shorter change rail facility, and the entire time for becoming rail process is very short, because
The unlock of this retaining mechanism and locking action must flexibly quickly；It must assure that the accuracy of locking when vehicle normal operation, no
Can because vehicle vibration or other reasons so that the wheel of locking is loosened and generate it is traversing so that occur safety accident, ensure
Retaining mechanism accuracy makes sure that wheel is locked in a certain suitable gauge position, otherwise, gauge changing is not only not achieved
Purpose, it is also possible to safety accident occur.
Chinese patent Authorization Notice No. is CN107757651A；Authorized announcement date:On March 6th, 2018；The applying date is 2017
On November 23, in；Denomination of invention:A kind of retaining mechanism for high-speed EMUs gauge-changeable bogie；The invention also provides one
The retaining mechanism of kind of gauge-changeable bogie, but the check lock lever in the invention had in the link motion with working arm it is certain
Lateral displacement, there are movement deads, are susceptible to stuck phenomenon, and there are prodigious security risks.
