Description
Technical field
The invention belongs to the technical field of Vehicle Leaf-spring Suspension system, a kind of be arranged on the big of frame inside
Tonnage balance suspension support.
Background technology
Refering to Fig. 1, Fig. 2, Fig. 3, the support 1-1 in current existing large-tonnage balance suspension support and crossbeam L-shaped steel plate
2-2 is bolted, and realizes elastic conjunction with axle.Due to this simple in construction, it is simple to assemble in the same direction, the advantages such as versatility is good,
Past is using always.But when under large-tonnage load, easily there is some drawback following in this support:
(1) existing balance bracket suspension general outline is del, wide at the top and narrow at the bottom, and rack body upper end is large end face, large end face
Edge profile is symmetrically distributed with 16 bolt boss 3-3, wherein 4 bolt boss both the above of large end face intermediate symmetry,
The rectangular distribution of following two, the linkage function produced less due to bolt boss quantity is not enough, easily causes bolt looseness, leads
Cause support to rupture.
(2) crossbeam L-shaped steel plate 2-2 deformation or fracture easily cause the inefficacy of support normal linkage function, ultimately result in support fracture, and
And L plate change space is little.
(3) linkage function that the bolt hole group being connected with longitudinal beam and bolt hole group 4-4 of the connecting plate of pedestal lower end produce is not
Foot, easily causes bolt looseness, causes support to rupture.
(4) support with balance axle be connected corner apertures group 5-5 is presented mal-distribution, cause screwed hole stress to cross major rupture.
(5) high bearing capacity is unreasonable with own wt and cost ratio, and stock utilization is low.
Summary of the invention
The invention provides the function by crossbeam L-shaped steel plate of a kind of simple in construction to be merged on support and form the big of horizontal tray
Tonnage balance suspension support, overcomes the above-mentioned deficiency of existing balance suspension support.
Technical solution of the present invention accompanying drawings is as follows: this support includes rack body, and this rack body upper end is large end face,
The bracket bolt holes group 1 being connected with longitudinal beam it is provided with, it is characterised in that described large end face rear portion on described large end face
Extend and connect the circular arc housing bearing 2 of V-arrangement distance rod on front-rear axle；It is with frame cross even below described bearing 2
The horizontal tray 3 being integrated with rack body connect；For balance axis hole 4 below described horizontal tray 3；Rack body lower end
For connecting the lower connecting plate bolt hole group 5 of lower connecting plate；Bolt boss is distributed in described bracket bolt holes group 1, described
Bolt boss is symmetrical along large end face edge profile, and wherein large end face intermediate distribution has six bolt boss rectangular, i.e. goes up
Face has three, below symmetry have three；There is bolt that through hole, the spiral shell of described large end face distribution are installed in described bolt boss
Bolt boss the first muscle 6 being distributed in wing-shaped connects.
Have 4 bolts that through holes are installed in described lower connecting plate bolt hole group 5 rectangular, have i.e. above two, symmetrical below
There are two.
Described bracket bolt holes group 1 and lower connecting plate bolt hole group 5 use circular arc camber transition.
Described both sides, large end face rear portion are provided with the outer muscle 7 of " eight word " shape.
Described bracket bolt holes group 1 and balance axis hole 4 circular arc camber housing 8 transition.
Base 9 upper end of described horizontal tray 3 is intersected with housing 8, lower end and black skin 10 round-corner transition, and uses limit muscle
11, mid-plane muscle 12 supports.
There is the second muscle 13 and the 3rd muscle 14 formed by three grooves at the rear portion of described horizontal tray 3, and the second muscle 13 is along balance
The axis distribution that axis hole 4 and the first bolt hole 15 in bracket bolt holes group 1 are formed, the 3rd muscle 14 along balance axis hole 4 with
The axis distribution that the second bolt hole 16 in bracket bolt holes group 1 is formed.
3 second bolt boss 17 with circle, described second bolt boss 17 are distributed outside described balance axis hole 4 circumference
On have blind threaded hole, upper end holes is symmetrical along the support plane of symmetry, with balance axis hole hole heart angle be 60 degree, lower end
One hole is on the support plane of symmetry.
The invention has the beneficial effects as follows:
(1) function of crossbeam L-shaped steel plate is merged on support by the present invention, forms the horizontal tray of integral type.This bracket can solve
The problem that the insoluble design space that L plate runs into when strengthening is not enough, and effectively reduce the deformation of support, carry energy
Power is significantly improved.Bracket uses Rouno Cormer Pregrinding Wheel transition with bottom surface, is distributed brace rod, is simultaneously connected with former L on the basis of this face
6 bolts of plate are cancelled.
(2) present invention increases by 2 bolt mounting holes in the bracket bolt holes group being connected with longitudinal beam；Lower connecting plate bolt hole group
4 are become by 2；With balance axle be connected corner apertures group is become 3 by 2, all of blind threaded hole of support is made into
Through hole whorl hole, the bolt connection reliability of support promotes.
(3) pedestal upper end V rod bearing region of the present invention is by there being the original solid housing making equal thickness into, and it is curved that the back side arranges great circle
Shell muscle, this structure is advantageous in that: a) avoiding the casting flaw that thick heavy in section is brought, this region matrix material intensity significantly carries
High；B) shortening boring feed distance, saving machine adds expense；C) fall weight, saves expense；D) local compliance improves, necessarily
V bar partial vibration is absorbed in degree.
(4) muscle traversing support between the bolt boss that the bolt boss being connected with longitudinal beam is connected with crossbeam is cancelled, and uses
Thick circular arc camber excessive structural form, it is to avoid stress concentrations.
(5) present configuration is simple, novel, lightweight, low cost, and product versatility is good, is suitable to batch production.
