Specific embodiment
As previously mentioned, conventional rails vehicle technology is difficult further to reduce rate of wheel load reduction, it is difficult to increase vehicle distortion
Road.To reduce rail vehicle rate of wheel load reduction, increases vehicle and distort road, the invention proposes one
Kind wheel can balance left and right wheels load to assembly, realize zero wheel unloading, and vehicle distortion road is significantly greatly increased.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Wheel provided in an embodiment of the present invention is to assembly, comprising: it takes turns to 1, primary spring 2, axle box 3 and balanced lever apparatus 4,
Structure is referred to shown in Fig. 1；
Balanced lever apparatus 4 includes:
Torsion bar 8；
Two bearing blocks 5 by bearing support at 8 both ends of torsion bar respectively, and bearing block 5 has for same steering structure
The connection structure of frame cooperation；
It is respectively fixedly connected with two torque arm 6 in 8 both ends of torsion bar；
It is pivotally mounted to two strut and ties 7 of two torque arm 6 respectively；Two axle boxes 3 in left and right are located at the installation of wheel shaft side
Strut and tie 7 is installed in primary spring 2, the other side；Two primary springs 2 and balanced lever apparatus 4 are to be centrosymmetrically arranged, structure
It is referred to shown in Fig. 1, Fig. 2 and Fig. 3.It is understood that torsion bar 8 is parallel to wheel shaft, it is ensured that the stress at 8 both ends of torsion bar is equal
It is even, guarantee its service life.And torsion bar 8 is located above wheel shaft, facilitates the assembly of balanced lever apparatus 4 and bogie frame.For
The torque that 4 both ends of balanced lever apparatus are subject to is balanced, two strut and ties 7 are respectively to be placed equidistant in the two sides of axle centre.
The device passes through the rotation width that balanced 4 bearing of lever apparatus and 3 bearing of axle box are formed can be with autobalance or so wheel load
Lotus, the specific working principle is as follows:
If primary spring 2 is L apart from axle center distance1, strut and tie 7 is L apart from axle center linear distance2, one system of left side
2 load of spring and 7 load of strut and tie are respectively PL1,PL2, 2 load of right side primary spring and 7 load of strut and tie are respectively PR1,PR2。
It is equal that 7 load of left and right strut and tie is balanced according to balanced lever apparatus 4, it may be assumed that
PL2=PR2 (1)
Similarly, following formula can be obtained according to the balance of axle box 3 to set up:
PL1L1=PL2L2 (2)
PR1L1=PR2L2 (3)
Primary spring 2 load in left and right can be obtained by formula (1) to formula (3) and meet following formula:
PL1=PR1 (4)
Formula (1) plus formula (4) obtain:
PL2+PL1=PR2+PR1 (5)
Above formula left end is the sum of 7 load of primary spring 2 and strut and tie, and as left side wheel load, right end are right side wheels
Load.The wheel known to formula (5) is equal always to the left side wheel load and right side wheels load of device, i.e., rate of wheel load reduction is
Zero, vehicle distortion track handling capacity can be significantly improved.
It can be seen from the above technical scheme that wheel provided in an embodiment of the present invention, to assembly, balanced lever apparatus utilizes
The load transmission of strut and tie and torsion bar realizes the adjusting of two side loads, it is ensured that left and right wheels institute is loaded to be consistent, effectively flat
The load of weighing apparatus left and right wheels, realizes zero wheel unloading, and vehicle distortion road is significantly greatly increased.
In the present solution, strut and tie 7 the axial direction for being axially parallel to primary spring 2, it is ensured that anti-work suffered by 3 two sides of axle box
Power thrusts are consistent, avoid the stability that its structure is influenced because of unbalance stress, while strut and tie 7 also being facilitated to adjust two axis in left and right
Load difference between case 3, structure are referred to shown in Fig. 1, Fig. 2 and Fig. 3.Further, the axial direction of the two is vertical
Direction convenient for transmitting load and is easily installed.
Specifically, the rotor shaft direction of strut and tie 7 and torque arm 6 is parallel to wheel to 1 axis, it is ensured that 6 end of torque arm is subject to
Torsion is axial perpendicular to torsion bar 8, is conducive to torque arm 6 and preferably applies torque to torsion bar 8, facilitates between left and right wheels load mutually
Transmitting realizes the automatic adjustment of left and right wheels load, to achieve the effect that balance.
In order to advanced optimize above-mentioned technical solution, torque arm 6 is vertically fixedly connected on torsion bar 8, it is ensured that torsion bar 8 was subject to
Torsion prevents torsion bar 8 from being influenced its structural behaviour by other component perpendicular to its axial direction, to guarantee its service life.
Preferably, strut and tie 7 is pivotally mounted to torque arm 6 by rubber arthrosis.Pass through turn of strut and tie 7 and torque arm 6
It is dynamic to cooperate the transmitting that 8 both ends torque of torsion bar can be realized, damping effect can also be played by rubber arthrosis.When left and right wheels are logical
When crossing distortion route and loaded not equal situation occur, then adjusted by way of torque transmits, it is ensured that left and right wheels by
Load be consistent, to realize zero wheel unloading.
In the present solution, being arranged symmetrically centered on two axle boxes 3, there is interchangeability, primary spring 2 and equilibrium can be convenient to
Lever apparatus 4 is centrosymmetrically arranged.Specifically, it is arranged symmetrically centered on two axle boxes 3, substantially axle box 3 is used for same system's bullet
The mounting structure that spring 2 cooperates is centrosymmetric arrangement, and it is equidistantly to set that two primary springs 2 arrive axle centre respectively
It sets.Similarly, axle box 3 is used for the arrangement that is also centrosymmetric with the mounting structure that balanced lever apparatus 4 cooperates.Balanced lever apparatus 4 is logical
It crosses and is centrosymmetrically arranged, so that the balanced end (as strut and tie 7) of balanced lever apparatus 4 is connected to the axle box 3 of left and right two
Diagonal end.When left and right wheels the situation of loaded unevenness occur by distorting route, load in the form of torque and is passed through into torsion
Bar 8 passes to low load wheel by top load wheel, realizes the automatic adjustment of wheel weight.
In order to advanced optimize above-mentioned technical solution, the connection structure that bearing block 5 is used to cooperate with bogie frame is
The fastness of connection is effectively ensured in bolt fastening structure.It is, of course, also possible to using other connection types, for example, welding and riveting
It connects, details are not described herein again.
The embodiment of the invention also provides a kind of using above-mentioned wheel to the bogie and rail vehicle of assembly, due to using
Above-mentioned technical solution, therefore it also just has corresponding beneficial effect, be specifically referred to it is described above, it is no longer superfluous herein
It states.
This programme is described further combined with specific embodiments below:
