Including two tie points, a tie point is arranged on reinforcing plate 35, and another tie point is arranged on adjacent left plate or the right side
On side plate.So as to be more uniformly stressed.
Preferably, the installation screwed hole set on the balance shaft support 1 uses independent built-in wire threaded insert structure.It is described
Installation screwed hole is not intended to balance shaft support 1 being connected to the mounting hole of longitudinal beam, but for by spring block 4 or other
Component is attached to balance shaft support 1.So as to without the tapping on balance shaft support so that whole branch need to be changed during screw thread breakage
Frame or again tapping are repaired.That is, balance shaft support upper screwed hole uses independent wire threaded insert structure, solves support spiral shell
Line breakage need to change the problem of whole support or the again maintenance difficult of tapping maintenance.
Steel-wire screw-socket, also known as screw insert, it is a kind of new threaded fastener, is by high intensity, high accuracy, surface light
A kind of concentric body of spring-like internal and external threads that the clean stainless steel wire with diamond-shaped cross-section is accurately process.Steel-wire screw-socket be for
The insert protected metal threaded hole and developed, is screwed in and is fastened in the screwed hole of one of connected piece, formation meets
International standard internal thread, shape are similar to helical spring, have higher hardness and preferable surface roughness.Steel-wire screw-socket is embedding
In the screwed hole for entering the low intensive engineering material such as Al alloys andMg alloys, cast iron, fiberglass, plastics, the M screw threads of standard can be formed, are had
There are bonding strength height, antidetonation, shock resistance and anti abrasive function, and energy dispersive stress protection matrix screw thread, greatly prolong matrix
Service life.Present invention preferably employs lock type steel-wire screw-socket.
Advantageously, spring block and the supply of material of balance shaft support component, to simplify suspension system assembly technology.
Referring to Fig. 2, connecting plate 8 is respectively arranged with two bottoms of balance shaft support 1, is passed through between two connecting plates 8
Hydraulic buffer 7 is connected with each other.Mitigate or suppress the vibration of braking balance suspension using hydraulic damper 7, especially holding
By side force with being vibrated during torque correlation.Specifically, the connecting plate 8 is connected releasably to the balance shaft branch
Frame 1, the both ends of the hydraulic buffer 7 are connected releasably to corresponding connecting plate 8 respectively.Advantageously, it is described
Hydraulic buffer 7 is adjustable-damping shock absorber.
In one alternate embodiment, leaf spring centre-to-centre spacing of the braking balance suspension at back axle is more than at propons
Leaf spring centre-to-centre spacing.So that the space at rear portion between U bolt and vehicle frame is larger, it is easy to assemble U bolt.Increase simultaneously
The roll stability of rear suspension.Advantageously, it is spacing on rear side of leaf spring to be adjusted to spacing in vehicle bridge closing spring block, to shorten rear spring
Length.
Specifically, the leaf spring of the braking balance suspension is obliquely installed in the longitudinal direction, to cause leaf spring centre-to-centre spacing
Gradually increase from front to back.It is of course also possible to use other modes or structure cause braking balance suspension at back axle
Leaf spring centre-to-centre spacing is more than the leaf spring centre-to-centre spacing at propons.It is pointed out that back axle and propons herein is relative to described disconnected
For two vehicle bridge (also referred to as axletree) that open type equalizing type of suspension is connected.In fact, propons herein will be six-wheel vehicle
Jackshaft.
In one alternate embodiment, the openend (big end) of V-type distance rod uses oscillating bearing structure, and carries butter
Mouth lubrication channel.This advantageously reduces the fault rate of V-type distance rod.The structure of oscillating bearing is simpler than rolling bearing, and its is main
It is made up of by one the inner ring of spherical outside surface and one outer ring of Internal Spherical Surface.The slidingsurface of oscillating bearing is spheric, also
Banking motion (i.e. aligning moves) can be made in the range of certain angle, when support shaft and axle housing hole nonconcentricity are larger, remained to
Normal work.Oscillating bearing can bear larger load, can particularly bear radial load, axial load or radially, axially
Simultaneous joint load.The requirement of installation accuracy is advantageously reduced, and adapts to the loading in composite of V-type distance rod.
Advantageously, in the oscillating bearing structure, composite is studded with the spherical outside surface of inner ring, therefore the bearing exists
It may result from lubricating in work.The relatively low oscillating motion of speed, and low speed rotation are generally used for, also can be in the range of certain angle
Make banking motion, when support shaft and axle housing hole nonconcentricity are larger, remain to normal work.
The present invention also provides a kind of multiple-axle vehicle, and the multiple-axle vehicle includes, positioned at anterior the first bridge (propons), being located at
Second bridge (jackshaft) at middle part and the 3rd bridge (back axle) positioned at rear portion, and braking balance suspension.The breakaway-element balance
Suspension is any braking balance suspension as described above.The braking balance suspension connects second bridge and the 3rd
Bridge.The braking balance suspension has two V-type distance rods, and the openend of a V-type distance rod balances with the breakaway-element
The balance shaft beam 3 of suspension is connected, and the other end is hinged with second bridge；Break with described the openend of another V-type distance rod
The balance shaft beam 3 of open type equalizing type of suspension is connected, and the other end is hinged with the 3rd bridge.
In the braking balance suspension of the present invention, balance shaft support 1 is connected to institute in the left and right outside of longitudinal beam 2
Longitudinal beam 2 is stated, and balance shaft beam 3 is consequently formed relative to 2 arrangement on the lower side of longitudinal beam while is located at longitudinal beam
The pipeline passway 9 of 2 inner side and the top of balance shaft beam 3；Avoid the need for the shortcomings that pipeline bypasses equalizing type of suspension.This
Outside, distance rod connecting seat 36 is provided with the balance shaft beam 3, for being connected with the openend of V-type distance rod.So as to V
The openend of type distance rod is connected on same component, rather than is connected on two balance shaft supports in left and right, avoids V-type from pushing away
