Secondary suspension of the present utility model is formed 6 and by being provided with of longitudinal register rubber pad 61 bogie side frame is connected with bolster elasticity, can either realize that bogie side frame 21 relative bolster 41 motions are to adapt to the distortion circuit and all to carry, can avoid the bogie side frame rhombus by the rational Match three-way rigidity again, the transmission of the power between bogie side frame 21 and the bolster 41 is provided simultaneously.Secondary suspension forms 6 by the normal spiral roof pressure that contacts 622 pairs of two-side elastic rubber blocks 624 of two screw mandrels of damping registration device 62, make elastic block rubber 624 be compressed distortion, form 6 for secondary suspension required damping of friction damping and positive pressure are provided, guaranteed the normotopia of side frames 21, avoid bogie side frame 21 that diamonding takes place, increased the diamond resistant rigidity of bogie side frame 21.
As shown in Figure 2, foundation brake rigging 5 of the present utility model adopts the frame mode of lower link composite brake beam in the prior art, and composite brake beam adopts chute-type with being connected of bogie side frame, helps alleviating the wheel eccentric wear; Be L-B type composite brake beam by brake beam mainly, the high break-in that is fit to Φ 915mm wheel becomes composition foundation brake multiplying powers 6.78 such as brake shoe.
As shown in Figure 8, double-acting elastic side bearing 7 of the present utility model has taken into full account the structure of container car, the anti-characteristics such as ability of sidewindering, adopted the long travel double-acting elastic side bearing, it comprises wearing plate 71, side bearing body 72, roller 73, Roller Shaft 74, adjusts backing plate 75 and longitudinal register piece 76.Side bearing body 72 is made up of sulfuration all-in-one-piece wearing plate bearing 721, multilayer cone rubber layer 722, taper spacer 723 and side bearing bearing 724.
Shown in Fig. 1～8, stressed and transmission power when the utility model moves is as follows:
If vertical force when getting on the bus, at first reaches bolster by abrasion dish in the cartridge 42 and double-acting elastic side bearings 7 and forms 4; Secondly, form 6 rubber pad 61 by secondary suspension and pass to bogie side frame and form on 2 the bogie side frame 21, this grade one side utilizes the vertical distortion of rubber pad 61 to have certain vibration damping, utilizes normal contact friction shock attenuation unit 62 that vertical dry friction vibration damping is provided simultaneously; Vertical force one tunnel reaches a side of axle box 31 by the spring in the single stage suspension device 3 34 via drawing strickle guide seat 22, another Lu Zejing wedge seat 23, secondary friction face 25, wedge body 26 reach the opposite side of axle box 31 by the spring in the single stage suspension device 3 35, utilize the friction face decay vertical vibration of the main friction locating piece 36,37 of axle box 31 both sides simultaneously, by longitudinal register rubber block 38 buffering wheels to forming 1 lateral vibration that is subjected to; At last, the vertical force that acts on axle box 31 both sides passes to wheel to forming on 1 axletree 11, the wheel 12 by axle box saddle face, antifriction-bearing box 32 with vertical load, finally reaches transmission and vibration damping that rail is realized vertical load; If power is from track, the transmission of its power is with opposite to getting on the bus.
The transmission of transverse force and vibration damping: transverse force mainly is because the application force that is produced in the operation of specific circuit and constructional feature, its transfer route is: at first, act on side-friction on transverse force on the cartridge 42 abrasion dishes and friction force, the double-acting elastic side bearing 7 and reach bolster and form 4; Secondly, utilize the lateral deformation of the rubber pad 61 of secondary suspension composition 6 transverse force to be passed on the bogie side frame 21 of bogie side frame composition 2, this grade one side utilizes the lateral deformation of rubber pad 61 to have certain vibration damping, utilizes normal contact friction shock attenuation unit 62 that horizontal dry friction vibration damping is provided simultaneously; Then, transverse force one tunnel reaches a side of axle box 31 by the transverse shear deformation of the spring in the single stage suspension device 3 34 via drawing strickle guide seat 22, another Lu Zejing wedge seat 23, secondary friction face 25, wedge body 26 reach the opposite side of axle box 31 by the spring in the single stage suspension device 3 35, utilize the friction face decay lateral vibration of the main friction locating piece 36,37 of axle box 31 both sides simultaneously, utilize longitudinal register rubber block 38 buffering wheels forming 1 lateral vibration that is subjected to; At last, act on the friction of transverse force on the axle box 31, transverse force is reached on antifriction-bearing box 32, axletree 11, the wheel 12 finally reach rail, realize the transmission and the vibration damping of transverse load by axle box 31 located lateral faces and saddle face; If power is come to track, the transmission of its power is with opposite to getting on the bus.
The transmission of longitudinal force and vibration damping: longitudinal force is mainly divided tractive force and braking force, and the effect route is opposite.Wherein the transfer route of tractive force is basic identical with transverse force before reaching single stage suspension to form 3, and difference is that the direction of power is for vertical; But the longitudinal force transmission that bogie side frame 21 and single stage suspension are formed between 3 then is: the longitudinal force that acts on the bogie side frame 21 utilizes the inclination angle of wedge body 25 will act on the power of secondary friction face 26 through wedge seat 23, be decomposed into the longitudinal force of wedge body 25, this power is delivered to a side of axle box 31 with longitudinal force and makes axle box 31 produce the motion that increases wheelbase at longitudinal direction by the main friction locating piece 37 on right side, thereby make between axle box 31 and drawing strickle guide 22 longitudinal register rubber locating piece 38 in linear deformation, longitudinal register rigidity both was provided, has made axle box 31 have radially function again.
