Description
Technical field
The invention belongs to support technology field, particularly relates to a kind of multiple bay for suspension system.
Background technology
Automobile suspension swinging arm assembly, be that suspension is primarily directed toward rod member between body of a motor car and wheel, bear start,
Braking, turn when longitudinal force and cross force, additionally it is possible to play distance rod effect, be determine vehicle performance critical piece it
One.The independent suspension such as macpherson suspension and double cross arm independent suspension has swing arm.
In suspension noun, the mechanism for connecting point-to-point transmission, the tie point of one end has two, cried " swing arm " (arm)；Two
All there was only a tie point " connecting rod " (link) in end.Each suspension swing arm body has two branch arms, has plenty of two points
Support arm is entirety, and X is to, the effect of Y-direction, Z-direction power during common vehicle traveling；Two branch arms having are independent zero
Part, it is fixed together by bolt etc., side force (Y during one of them branch arm vehicle traveling parallel with Y-direction
To) and vertical force (Z-direction) effect, this branch arm is referred to as tranverse connecting rod more, and another is with X to parallel or have the arm of small angle
The active force of carrying longitudinal direction (X to), this branch arm are referred to as distance rod more.
Casting technique can form complicated shape, and present casting swing arm body uses ductile cast iron material more, impacted
Shi Rongyi produces brittle failure, and very big to safety effects, in order to ensure the reliability of casting swing arm body, swing arm body, which is made, to be compared
It is thick, because casting quality is big, with the development trend of present vehicle light-weight design and requiring incompatible with.
Swing arm body rushes weldment body and includes many stamping parts, it is necessary to substantial amounts of diel much using rushing weldment,
Weld jig and welding robot are also needed to, meanwhile, mould when stamping parts intensity difference, low precision, complex management, batch 50,000 are few
It is also very high to have cost, qualifying point also compares more, and space-consuming is larger during arrangement.
The swing arm of present independent suspension is also more and more using forging, and the intensity of forging is very high, by smart after machining
Degree is also higher, and passenger car is also more and more using the vehicle of the swing arm of wrought aluminium, and weight also reduces a lot, commercial car independent suspension
Swing arm frequently with forged steel pieces.Due to forging technology can not be formed complexity structure, no matter so the forged steel pieces of commercial car or
The wrought aluminium part of passenger car is mostly connecting rod (l ink) form, but independent suspension needs swing arm structure, so having to two forgings
Part connecting rod assembly forms swing arm structure together.
It is as described in Figure 1 the swing arm body assembly of prior art, including front lining 01, distance rod 02, back bush 03, horizontal company
Bar 04, bolt 05 and ball pin 06, swing arm body assembly are made up of two connecting rods, and the two connecting rods are individual parts, and longitudinal is
Distance rod, horizontal for crossbeam, the two is bolted on together.Because the swing arm of independent suspension also needs to stable connection
Bar, shock absorber etc., but the swing arm body assembly of prior art can not connect.
The content of the invention

Inside and outside and exterior circular column 18, the inner cylinder 29 of the rack body 21 are connected, both companies of the increase of sphenoid 17
Connect intensity；It is connected before rack body 21 with distance rod fixed station 12, mainboard 13 and side plate 15, upper reinforcement 14 and lower reinforcement 30
Both bonding strengths of increase；Mainboard 13 is mutually connected in above-below direction with side plate 15 to have dislocation, and increases the intensity of support；Rack body
It is connected after 21 with back plate 26, both bonding strengths of the rear increase of reinforcement 25；There are two portraits 27 on rack body 21, two perpendicular
Version 27 is parallel to be separated by a certain distance, and two portraits 27 respectively have a shock absorber mounting hole 28.
There is distance rod fixed station 12 on the mainboard 13, there are two distance rods to fix via 11 on distance rod fixed station 12,
Two distance rods fix the line of via 11 and 90 ° of the angle b ＜ of portrait 27；The thickness of mainboard 13 is a2, distance rod fixed station
The lower plane distance of plane to mainboard 13 is a1 on 12；There are stabilizer link mounting hole 16, the thickness of side plate 15 on the side plate 15
For a3, a1 ＞ a2 ＞ a3, stepped thickness change is formed, with proof strength and lightweight simultaneously；Mainboard 13 is with side plate about 15
Dislocation, increase the intensity of multiple bay 1, also have upper reinforcement 14, lower reinforcement 30 further between mainboard 13 and side plate 15
Increase the intensity of multiple bay 1.
There are screwed hole 20, the external screw thread end face 19 of exterior circular column 18 and inner circle in the exterior circular column 18 and inner cylinder 29
In one plane, this plane is parallel with plane after rack body 21 for the internal thread end face of cylinder 29, and is higher than rack body
1~3mm of plane after 21.
It is connected on the snap fit 23 with back plate 26, both bonding strengths of the rear increase of reinforcement 25；The inner side of snap fit 23 has
Snap fit end face 22, snap fit end face 22 is parallel with external screw thread end face 19 and is separated by a certain distance, this distance and the width of tranverse connecting rod 3
It is identical；Have on snap fit end face 22 and hook bottom 24, hooking bottom 24 can both avoid causing stress concentration when processing snap fit end face 22, can prevent again
Interfere above with tranverse connecting rod 3 below back plate 26.
The multiple bay 1 of the present invention is stuck on tranverse connecting rod 3, snap fit end face 22 and external screw thread end face 19 and tranverse connecting rod 3
Front and rear sides face is bonded, and is threaded into respectively in hole 20 by via in tranverse connecting rod 3 with two bolts, by the multi-functional of the present invention
Support 1 is fixed on tranverse connecting rod 3；Distance rod 2 is fixed on distance rod fixed station 12 with bolt and nut；Installed by shock absorber
Hole 28 is connected together the lower end of shock absorber 4 with the present invention with bolt and nut；Will be steady with nut by stabilizer link mounting hole 16
The lower end of fixed pole connecting rod 5 connects together with the present invention, completes fixation and other parts and the peace of the present invention of the present invention itself
Dress, as shown in Figure 6.
Operation principle
Principle 1：
Mainboard 13 misplaces with side plate about 15, increases the intensity of the present invention, also has upper strengthen between mainboard 13 and side plate 15
Muscle 14, lower reinforcement 30 further increase the intensity of the present invention.
Principle 2：
Snap fit end face 22 is parallel with external screw thread end face 19 and is separated by a certain distance, this distance and the width phase of tranverse connecting rod 3
Together, after the present invention is fixed to tranverse connecting rod 3, snap fit end face 22 is bonded with external screw thread end face 19 with tranverse connecting rod 3, when bolt and screw thread
When the connection of hole 20 loosens, the present invention will not be caused to be come off from tranverse connecting rod 3, the driving safety of vehicle is fully ensured that, subtract simultaneously
Stove bolt is acted on by power and torque, improves the reliability of suspension.
The present invention has carried out detailed explanation by preferred embodiment.However, by studying carefully above, to each
Apparent to the change of embodiment and increase and those of ordinary skill in the art.It is intended that it is all this
A little changes and increase all fall in the scope that the claims in the present invention are protected.
