Description
Technical field
The present invention relates to automobile manufacturing field, more particularly to a kind of automobile rear independent suspension swing arm mounting bracket assembly.
Background technology
The effect of Lower suspension arm of automotive suspension assembly is to be coupled vehicle frame or subframe, plays carrying and guiding two, while
Decayed by the flexibly jointed chain of rubber bushing and the vibration of vehicle body is transferred to by road surface.
As shown in Figure 1-2, it includes being formed by swing arm upper body 1 and the butt welding of swing arm lower body 2 conventional bottom arm assembly at present
Swing arm body, swing arm body have two vehicle frame connection ends and a knuckle connection end, one of vehicle frame connection end sets
There is front lining bushing pipe 3, another vehicle frame connection end is provided with backsight pipe having lining 4, the knuckle connection end is provided with three for filling
Mounting hole with ball-stud socket, is divided into inner the first mounting hole 6 and two outer the second mounting holes 7.Due to swing arm upper body,
Swing arm lower body is metal plate punching part, and for the ease of punch forming, swing arm upper body and swing arm lower body are typically designed to more put down
Smooth structure, as shown in figure 3, swing arm this body section that the two butt welding is formed is usually more regular rectangle, yet with
Swing arm assembly bears larger load, and to meet its intensity and endurance quality requirement, swing arm upper body and swing arm lower body then need to set
Count wider, its material thickness also requires that thicker, causes it that more spaces are needed in arrangement, and interference is brought to suspension arrangement
The problems such as, while can also increase the weight of swing arm assembly, automotive light weight technology design requirement is unsatisfactory for, also cause vehicle comfortableness meeting
Reduce, while bringing the increase of cost.For simultaneously for the knuckle connection end of swing arm body, under vehicle environment, power and
Torque is delivered to swing arm upper body 1 and swing arm lower body 2 by the bolt through three mounting holes, is found by mechanical analysis
It is big by stress in three mounting hole central areas of knuckle connection end, as shown in figure 4, two of the knuckle connection end
The section that second mounting hole goes out will further improve intensity to be uniformly distributed on this architecture basics, can only be by increasing steel plate
Thickness is realized, but can so cause the increase of weight and cost.
In addition, car is in the process of moving, often has stone, foreign matter etc. and splash and bump to lower swing arm.If things go on like this,
Lower swing arm damage, the particularly bottom of lower swing arm are may result in, because stone, foreign matter are typically to splash from bottom, so
The partial destruction can be more serious, substantially reduces the service life of whole lower swing arm.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of automobile rear independent suspension for proposing
Swing arm mounting bracket assembly.
To achieve these goals, present invention employs following technical scheme：
A kind of automobile rear independent suspension swing arm mounting bracket assembly, including by swing arm upper body and the swing arm of swing arm lower body butt welding
Body；The two ends and middle part of the swing arm body are provided with connecting elements, and the connecting elements of swing arm body one end is double with vehicle body
Ear hinge bracket is connected, and other end connecting elements is connected with rear suspension knuckle, and the connecting elements connection positioned at middle part is laterally steady
Fixed pole；The bottom of the swing arm body is coated with preventing rubber layer, and the preventing rubber layer prevents from flying for protecting lower swing arm
Stone, foreign matter for splashing etc. and lower swing arm directly contact；
The swing arm body has two vehicle frame connection ends and a knuckle connection end, before one of vehicle frame connection end is provided with
Bushing bushing pipe, another vehicle frame connection end is provided with backsight pipe having lining；Served as a contrast between swing arm center and back bush on the swing arm body
Position between pipe, swing arm upper body and swing arm lower body are respectively equipped with and corresponding concave towards the intrinsic rectangle deep gouge of swing arm.
Preferably, the area that the preventing rubber layer is covered is the half of swing arm body peripheral area.
Preferably, the thickness of the preventing rubber layer is 2.2-2.4mm
Preferably, the thickness of the preventing rubber layer is 2.3mm.
Preferably, the knuckle connection end is provided with ball stud mounting hole, is divided into inner the first mounting hole and outer
Two the second mounting holes.
Preferably, the swing arm body cross-section at the rectangle deep gouge is in dumbbell shaped, greatly improves its intensity, without increasing
Swing arm material thickness and swing arm width.
Preferably, reinforcement is provided with the swing arm lower body between two the first mounting holes raised, greatly improves knuckle company
Connect end and bear load-carrying ability, it is to avoid the stress concentration at ball stud mounting hole.
Preferably, liquid-leaking nozzle is equipped with the rectangle deep gouge of the swing arm upper body and swing arm lower body, for application leakage.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, in car rear suspension lower swing arm bottom covering preventing rubber layer, stone, foreign matter of splashing etc. collide with preventing rubber
On layer, it is to avoid with lower swing arm directly contact, so as to be played a protective role to lower swing arm, effectively increase the service life；Rubber is prevented
Into the half of swing arm body peripheral area, because of stone, foreign matter, generally from bottom, splashing comes up the area design that sheath is covered, institute
Stone, foreign matter etc. are kept out with the preventing rubber layer of swing arm body bottom portion covering top link body peripheral half of the area area enough
Collide with, while again can material-saving, reduce production cost；The thickness of preventing rubber layer is designed to 2.3mm, by repeatedly examination
Test, can be kept out under the intensity that stone, foreign matter etc. collide with ensureing using the preventing rubber layer of the thickness, the elasticity of preventing rubber layer
It is minimum value, causes the secondary of stone, foreign matter etc. to collide with because preventing rubber layer elasticity is excessive so as to be prevented effectively from, the whole bottom
The barrier propterty of arm is more preferably.
2nd, swing arm assembly is set by the position between the swing arm center of swing arm upper body and swing arm lower body and backsight pipe having lining
Rectangle deep gouge is put, makes the swing arm body cross-section at rectangle deep gouge in dumbbell shaped, so as to improve the intensity of swing arm assembly, therefore
Swing arm material thickness and swing arm width need not be increased just can provide enough intensity and endurance quality；Simultaneously two on swing arm lower body
Reinforcement is provided between individual first mounting hole raised so that the intensity at the ball stud mounting hole position of knuckle connection end is improved, and is carried
Its ability loaded high, without increasing steel plate thickness.
