Description
Technical field
The utility model belongs to self-dumping undercarriage for automobile field, in particular to a kind of adjustable rear.
Background technique
In recent years, national truck traffic Frequent Accidents, truck back protective device reach the crash compatibility of other vehicles
When less than 3 points of loads, every loading force is 50kN or is equivalent to 25% horizontal load of vehicle maximum design total mass and (takes
The two smaller value) requirement, in addition terrain clearance is not able to satisfy no more than 500mm.
The lower edge terrain clearance of existing dumper rear is not more than 550mm, every loading force when 3 points of loads
For 25kN, the disadvantage is that terrain clearance is high, proof strength requires and security reliability lower than existing structure poor.
Summary of the invention
The purpose of the utility model is to provide a kind of adjustable rear, every loading force when meeting 3 points of loads
For the requirement of 50kN or 25% horizontal load (taking the two smaller value) for being equivalent to vehicle maximum design total mass, there is structure
Simply, low cost and the convenient advantage of installation and adjustment, are able to satisfy full strain dumper requirement.
The purpose of this utility model is achieved through the following technical solutions:
A kind of adjustable rear, including left and right two rear protecting brackets 1, left and right two rear protecting connecting brackets 2,
Reinforcing rib 3, backing plate 4 and rear protecting crossbeam 5, the backing plate 4 are fixedly connected on rear protecting crossbeam 5, and the rear protecting connects
It connects bracket 2 to be fixedly connected on backing plate 4, the reinforcing rib 3 is fixedly connected in rear protecting connecting bracket 2 and backing plate 4, described
1 upper end of rear protecting bracket offer eight for the first through hole 11 that are connected with longitudinal beam outside of belly bolt, rear protecting bracket 1
Lower end opens up that there are six for the second through-hole 12 for being connected with 2 bolt of rear protecting connecting bracket, the rear protecting connecting bracket 2
On offer third through-hole 21 for being connected with 1 bolt of rear protecting bracket, have 8 column third through-holes 21, each column hole from right to left
Column pitch is 50mm.
It has the beneficial effect that:
The utility model can be adjusted for the rear overhang of different dumpers, realized generalization, met
The installation and intensity requirement of GB11567-2017.In dumper unloading, rear can be adjusted to crossbeam relative to a left side
The lesser indentation state of distance of the right connecting bracket on vehicle front-rear direction, the loading space interference for avoiding and lifting, takes into account safety
And requirement.
Detailed description of the invention
Fig. 1 show the axis side schematic diagram of the utility model rear；
Fig. 2 show the schematic side view of the utility model rear；
Fig. 3 show the structural schematic diagram of the utility model rear protecting or so bracket；
Fig. 4 show the structural schematic diagram of the utility model rear protecting or so connecting bracket.
Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below in conjunction with the attached of the utility model
Figure, clearly describes technical solutions of the utility model.
The utility model use is mounted on the tail portion of frame assembly, wherein rear protecting or so bracket on self-dumping undercarriage for automobile
Upper end is connected on vehicle frame left-right longeron, and lower end is spirally connected with left and right connecting bracket, left and right connecting bracket rear end and stiffening plate assembly
Welding, stiffening plate assembly while and beam welding.
As depicted in figs. 1 and 2, the utility model provides a kind of adjustable rear, left part and right part
Symmetrically, a kind of adjustable rear, including control two rear protecting brackets 1, the two rear protecting connecting brackets 2 in left and right, add
Strengthening tendons 3, backing plate 4 and rear protecting crossbeam 5, the backing plate 4 are fixedly connected on rear protecting crossbeam 5, the rear protecting connection
Bracket 2 is fixedly connected on backing plate 4, and the reinforcing rib 3 is fixedly connected in rear protecting connecting bracket 2 and backing plate 4, described
1 upper end of rear protecting bracket offers eight for the first through hole 11 that are connected with longitudinal beam outside of belly bolt, under rear protecting bracket 1
End is opened up there are six for the second through-hole 12 for being connected with 2 bolt of rear protecting connecting bracket, in the rear protecting connecting bracket 2
Offer 8 column, each column two third through-holes 21 for being connected with 1 bolt of rear protecting bracket.
(left side is only shown) as shown in Figure 3,1 left upper end of rear protecting bracket has 8 first through hole 11, passes through bolt and vehicle
The frame stringer outside of belly is connected；1 bottom righthand side of rear protecting bracket have 6 the second through-holes of end 12, this 6 end mounting holes can with it is rear
Alignment is bolted in the three adjacent column mounting holes of protection connecting bracket 2, and the macropore in 1 Fig. 3 of rear protecting bracket is for subtracting
It reuses.
As shown in Figure 4 (only show left side), there are 8 column third through-holes 21 from right to left, in vehicle front-rear direction between adjacent column
On distance be 50mm, each column hole column pitch is 50mm, and 21 vertical axis of third through-hole of each column is overlapped.
In state shown in Fig. 2, the three column third through-holes 21 from left to right of rear protecting connecting bracket 2 by bolt with
Rear protecting bracket 1 connects, and rear is in stretching state.Pass through different groups of (the every group of mounting hole of third through-hole 21 of selection
It is made of 3 adjacent column hole locations) it is installed, crossbeam is adjustable relative to rear protecting or so bracket on vehicle front-rear direction
Relative distance, one shares 6 kinds of states, to adapt to the rear overhang requirement of different dumpers.
As shown in Figure 1, the rear end of rear protecting connecting bracket 2 is welded on backing plate 4, backing plate 4 is welded on crossbeam 5, is reinforced
Muscle 3 is welded in backing plate 4 and rear protecting or so connecting bracket 2 simultaneously, plays reinforcement effect.
The utility model is tested on rigid rack, when 3 points of loads, the positions of the right and left outside forces away from
Vertical plane 975mm from longitudinal direction of car center line, when loading force is loaded into 5kN by 0kN, crosshead displacement is linear with loading force
Variation, maximum deformation quantity 35mm, maximum stress value are less than yield strength 500MPa, and whole process is not plastically deformed, full
The intensity requirement of sufficient GB11567-2017.
The rear of the utility model is on dumper, being mainly used for meeting the road clearance of GB11567-2017
It is required that and 3 rate of loading requirements.For the rear overhang requirement for meeting different dumpers, the utility model is after existing dumper
Adjustable device is increased on the basis of protective device, has accomplished generalization.In addition, in dumper unloading, after being adjusted flexibly
The state of protective device, the loading space interference for avoiding and lifting, takes into account safety and requirement.
