It is connect with 1 ' of framework.
Existing bogie, two groups of motors are arranged on the longitudinal centre line of bogie, and two groups of teeth roller box is located at bogie
Two outsides of longitudinal center, for bogie under motor effect, two gear-box counter-forces will cause the unbalance loading of framework and wheel pair, and lead
It causes the more significant wheel weight of same axle uneven, has certain influence to traffic safety.
As shown in Figure 1, motor is arranged in centre, gear-box is disposed adjacent at wheel, and the two is connected by shaft coupling.With
The vehicle of 12ton axis heavy duty is illustrated, and when vehicle is in starting state, the counter-force of gear-box sunpender is very big, often reaches close
20kN, the torque very little of motor, often only 1000Nm, the two cannot result in framework and axle, wheel in two lateral balances
Unbalance stress.
Existing patent CN101190684A, single motor driving steering frame, two groups of axle gear boxs of disclosed bogie
Be all located on framework longitudinal centre line, but two groups of teeth roller box sunpender and gear box bracket are located at the same side of framework, i.e., with
The left side of framework longitudinal center biasing, so that front and back gear-box does not have interchangeability.
Therefore, it is necessary to provide a kind of bogie solution problem above.
Summary of the invention
The purpose of the present invention is to provide set in a kind of gear-box, motor offset bogie, with solve because of gear-box power
Caused by the uneven problem of framework unbalance loading, axle unbalance loading, wheel weight, and front and back gear-box is made to have interchangeability.
The technical scheme is that a kind of bogie include equipped with the frameworks of two side bars, two groups of wheels to, brake disc, set

Above-mentioned bogie will be set in gear-box, and motor biasing efficiently solves the left and right sides of the framework of installation bi-motor
The problem of unbalance stress, the gear-box counter-force that the balanced framework left and right sides is born, it is vertical that gear is born in the balanced axle left and right sides
Engagement force, the unbalance loading of left and right wheels weight are also balanced therewith.
Preferably, the gear-box sunpender is located in the extensions of gear-box length direction, and is hung by gear box bracket
In the frame underneath.
Preferably, two gear-boxes and gear-box sunpender are located at the two sides of the framework cross central line and are located at institute
State the middle part of framework longitudinal direction.
Preferably, two gear-boxes and gear-box sunpender are concordant with the longitudinal centre line of the framework.
Preferably, two gear-boxes and gear-box sunpender close on the longitudinal centre line of the framework and are staggered.
Gear-box and gear-box sunpender or the left and right sides on the longitudinal centre line of framework or positioned at framework and
Close on longitudinal centre line setting.Compared to the prior art, front and back gear box bracket is completely placed in the middle or separation controls, so that front and back tooth
Roller box has interchangeability.
Preferably, the brake disc is axis disc brake rotor, and quantity is two groups, closes on wheel pair respectively and along the framework
Longitudinal centre line is in be oppositely arranged with motor.
Preferably, the brake disc is Wheel-type brake disc, and quantity is four groups, respectively with two groups of wheels to connection.
That is the gear-box middle-containing structure equal energy on the bogie of axis disc brake rotor or the bogie of Wheel-type brake disc
It uses.
Compared with the relevant technologies, the invention has the benefit that will be set in gear-box, motor biasing, gear-box sunpender
Positioned at the design structure of middle seated position, framework unbalance stress can be effectively solved the problems, such as.It is framed in transverse direction (Y-direction) balanced
Gear-box counter-force is born, axle bears gear mesh force in left and right sides equilibrium, and the unbalance loading of left and right wheels weight is also balanced therewith.

Embodiment two
As shown in figure 3, the present embodiment and the difference of embodiment one are: two described gear-box 6a, 6b and gear-box sunpender 8 are described
Two sides of 1 transverse center of the framework and longitudinal center for closing on the framework 1 is staggered.I.e. in the longitudinal middle part of framework 1 in a left side
The right side is staggered.
Comparative example
Two simplified examples, a gear-box offset bogie are listed below, a gear-box middle calculates the two
As a result it compares and analyzes, to prove that gear-box middle bogie has the superiority of load equalization.
Gear-box offset structure and each design parameter of middle structure bogie are as shown in the table:
The code name of distance in upper table is as shown in Figure 1.
Each design parameter in upper table is calculated as follows:
(1) gear-box offset bogie calculates process are as follows:
The engagement force f of big pinion gear when starting torque, it is assumed that it is downward that it acts on the direction in pinion gear, is set as just.
f=M/r*1000=25564
Engagement force causes the vertical force Faz1 of axle
Faz1=-f
The vertical force Fdz that engagement force causes gear-box sunpender to act on gear block
Fdz=M*(1+i)/L1*1000=1078*(1+7.3)/488=18335
Fdz causes the vertical force Faz2 of axle to the torque at framework center
Faz2=M*(1+i)/(B1+B2)*1000=1078*(1+7.3)/1000*1000=8947
The vertical force Faz that axle is generated by starting torque
Faz= Faz1+ Faz2=-25564+8947=-16617
The off-load dQ1 of wheel 1 caused by therefrom
dQ1= Faz*L4/(L3+L4)=-16617*1223/1500=-13548
The off-load dQ2 of wheel 2 caused by therefrom
dQ2= Faz*L3/(L3+L4)= -16617*227/1500=-2514
Cause the wheel load difference dQ of wheel 1 Yu wheel 2
dQ= dQ1- dQ2=-13548+-2514=-11034
(2) difference of the design parameter of gear-box middle bogie and gear-box offset bogie is in L3/L4, gear-box
Set the measuring and calculating process of formula bogie are as follows:
The engagement force f of big pinion gear when starting torque, it is assumed that it is downward that it acts on the direction in pinion gear, is set as just；
f=M/r*1000=25564
Engagement force causes the vertical force Faz1 of axle
Faz1=-f
The vertical force Fdz that engagement force causes gear-box sunpender to act on gear block
Fdz=M*(1+i)/L1*1000=1078*(1+7.3)/488=18335
Fdz causes the vertical force Faz2 of axle to the torque at framework center
Faz2=M*(1+i)/(B1+B2)*1000=1078*(1+7.3)/1000*1000=8947
The vertical force Faz that axle is generated by starting torque
Faz= Faz1+ Faz2=-25564+8947=-16617
So far, two kinds of LOAD FOR results are all consistent.
The off-load dQ1 of wheel 1 caused by therefrom
dQ1= Faz*L4/(L3+L4)=-16617*850/1500=-9416
The off-load dQ2 of wheel 2 caused by therefrom
dQ2= Faz*L3/(L3+L4)= -16617*650/1500=-7200
Cause the wheel load difference dQ of wheel 1 Yu wheel 2
dQ= dQ1- dQ2=-9416+7200=-2216
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to be said using the present invention
Equivalent structure or equivalent flow shift made by bright book and accompanying drawing content is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
