Embodiment
In order to make it easy to understand, the invention will be further described below in conjunction with the accompanying drawings.
Embodiment one
Referring to Fig. 1 and Fig. 2, Fig. 1 is a kind of duplex pull rod for straddle-type monorail train that the embodiment of the present invention one provides
The schematic diagram of formula single-axle bogie, Fig. 2 are the schematic diagrames of antidive device.
The dual-pulling rod type single-axle bogie that embodiment one provides includes framework body 1, and the both sides of framework body 1 are provided with anti-point
Head device, antidive device include torsion bar 8, torque arm 6 and connecting rod 5, wherein, the length direction and straddle-type monorail train of torsion bar 8
Fore-and-aft direction it is parallel, torsion bar 8 is rotatably connected with framework body 1, torsion bar 8 relative to framework body 1 around torsion bar 8 axis rotate；Water
Two torque arm 6 that plain cloth is put are located at the both ends of torsion bar 8, and are fixedly connected with torsion bar 8, moreover, two torque arm 6 are located at torsion bar 8
The same side；Connecting rod 5 and 6 corresponding setting of torque arm, connecting rod 5 is vertically arranged, and the lower end of connecting rod 5 and torque arm 6 are away from torsion bar 8
One end is hinged, and upper end is connected with car body.
The operation principle of antidive device is as shown in figure 3, because torsion bar 8 is parallel to the fore-and-aft direction of straddle-type monorail train
Arrangement, so when car body is nodded, a relative framework body 1 in two connecting rods 5 moves up, and another is with respect to framework
Body 1 moves down, and then two horizontal positioned torque arm 6 have a mutually opposing torque respectively for torsion bar 8, i.e. in Fig. 3
M1 and M2, torsion bar 8 bear moment of torsion and produce the elasticity of torsion deformation, play a part of torsion-bar spring, the reaction torque of torsion-bar spring
The in opposite direction of the angular displacement nodded always is produced with car body, so as to constrain the nodding of car body.
Nodded when car body is not present, and simply overall vertical vibration when, because torsion bar 8 is rotatably connected with framework body 1, institute
It is to make two torque arm 6 produce around the axis of torsion bar 8 to rotate in same direction with two connecting rods 5, then the relative framework body 1 of torsion bar 8 is around torsion
The axis of bar 8 rotates, and without torsion-bar spring effect occurs, therefore the resilient flexible of secondary suspension system Central Plains spring will not be produced
It is raw to influence.
As depicted in figs. 1 and 2, in order to be connected with framework body 1, framework connecting seat 7 is installed on torsion bar 8, can be in structure
The bearing or rubber snap ring being set on torsion bar 8 are provided in frame connecting seat 7, to reduce rotation friction.
In order to not influence transverse shakiness of the car body with respect to framework body 1 and gyration, the upper end of connecting rod 5 is typically cut with scissors with car body
Connect, as shown in Fig. 2 the upper end of connecting rod 5 is provided with car body connecting seat 4, connecting rod 5 is hinged with car body connecting seat 4.
In order to reduce friction, rubber can be respectively provided with the junction and connecting rod 5 of connecting rod 5 and torque arm 6 and the junction of car body
Glue bushing.
Embodiment two
Referring to Fig. 2, in embodiment one, torsion bar 8 and torque arm 6 be integral type structure, the difference of embodiment two and embodiment one
It is only that, in embodiment two, torsion bar 8 is detachably connected with torque arm 6, is so conveniently replaceable torque arm 6.
In various embodiments above, in order to adapt to the different distance between car body and framework body 1, connecting rod 5 can be designed
To be length-adjustable.The material of torsion bar 8 can be superior alloy steel or hot rolling spring steel, such as 42CrMo, 60CrMnMo etc..
Single-axle bogie only has an axletree, so belonging to unstability structure in vertical plane, i.e., when single-axle bogie list
Solely be placed on when on track girder by self structure be unable to steady operation, it is necessary to vehicle assembling after rely on car body constraint
Rock-steady structure could be turned into, and when being acted between wheel track in the tractive effort at wheel rim or brake force of travelling wheel, tractive force or system
Power can also produce a turning torque for causing to nod to framework body 1, in order that bogie more smoothly moves ahead, Ke Yi
One end of framework body 1 is provided for the balancing pole 2 and draw bar 3 of connection body, as shown in figure 1, balancing pole 2 and draw bar 3 are flat
Row arranges and is located at the center line of framework body 1 in same vertical plane that the position of balancing pole 2 is higher than the axis of axletree, draw bar 3
Position be less than the axis of axletree, will be produced so when bogie is pulled power or Braking, in balancing pole 2 enough
Active force with balance traction (or braking) turning torque caused by power, suppress the motion of nodding of framework body 1.
In order to improve security, the relative equilibrium bar 2 of framework body 1 and the other end of draw bar 3 can be provided with traveling
Auxiliary wheel (not shown), traveling auxiliary wheel are generally solid wheel, it is for instance possible to use cast aluminium core wheel and polyurethane rubber knot
Structure.
The present invention also provides a kind of straddle-type monorail train, and the straddle-type monorail train includes double disclosed in above-described embodiment
Rod-pulling type single-axle bogie.Because dual-pulling rod type single-axle bogie has above-mentioned technique effect disclosed in above-described embodiment, therefore
Straddle-type monorail train with the dual-pulling rod type single-axle bogie is no longer superfluous herein equally with above-mentioned technique effect
State.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention.
A variety of modifications to embodiment will be apparent for those skilled in the art, as defined herein general
Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, the present invention will not
Embodiment illustrated herein can be restricted to, and is to fit to consistent with principles disclosed herein and features of novelty most wide
