3 Terms and Definitions
What is defined in GB/T 4549.2-2004, and the following terms and definitions are
applicable to this document.
3.1 Frame-brace Bogie
Frame-brace bogie refers to three-piece cast steel bogie, which implements elastic
Frame bogie refers to a running gear, which generally sets up components like
wheelsets axle box device, suspension damping device and foundation brake gear;
adopts bogie frame as the installation foundation of various components; bears vehicle
body and loading weight; rotates in relative to the vehicle body.
NOTE: definition 2.17 in GB/T 4549.2-2004 is modified.
3.10 Bogie Frame
Bogie frame refers to a basic bearing structure, which is between the primary and
secondary suspension device, and implements the transmission of force from vehicle
body to wheel and axle.
NOTE: definition 3.1 in GB/T 4549.2-2004 is modified.
4 Main Structure
4.1 Frame-brace Bogie
Frame-brace bogie belongs to three-piece cast steel bogie. It is mainly constituted of
adapter, elastic positioning member, wheel and axle, side frame, central spring
suspension device, swing bolster, basic braking device, frame-brace device and elastic
side bearing, etc. In accordance with difference in the location of frame-brace device
and swing bolster, frame-brace bogie can be divided into lower frame-brace bogie and
central frame-brace bogie.
4.2 Swing Bogie
Swing bogie belongs to three-piece cast steel bogie. It is mainly constituted of adapter,
pedestal rocker seat (primary elastic swing device), wheel and axle, side frame, central
spring suspension device, swing bolster, spring plank, rocker seat, rocker seat bearing,
foundation brake gear and elastic side bearing, etc.
4.3 Sub-frame Radial Bogie
Sub-frame radial bogie refers to three-piece self-guided radial bogie. It is mainly
constituted of wheel and axle, side frame, central spring suspension device, swing
bolster, foundation brake gear, primary rubber-metal pad, wheelsets radial device and
elastic side bearing, etc.
4.4 Frame Bogie
Frame bogie is a bogie, with the frame of an integral structure, which is brought
together through rigid connection. It is mainly constituted of bogie frame, wheelsets
axle box (axle box suspension device), foundation brake gear, traction device and
elastic side bearing, etc. Generally speaking, bogie frame is integrally welded through
steel plates.
g) The clearance of the inner and outer ring round spring in the radial direction
should not be less than 2.5 mm; the minimum shall not be less than 1.5 mm;
h) In terms of bogie which has a damping device, spring’s deflection margin
coefficient shall be more than, or equals to 0.7. In terms of bogie which does
not have a damping device, spring’s deflection margin coefficient shall be more
than, or equals to 0.9.
