Embodiment
In order to deepen to be appreciated and understood by of the present utility model, with reference to the accompanying drawings and detailed description, further explain
Bright the utility model.
Embodiment 1：Referring to Fig. 1, Fig. 2, a kind of connecting-rod separated suspension fatigue durability testing stand of automobile five, the testboard
Frame includes automobile body clamp 11, tire tool 12, slide unit 13, connecting rod 14, actuator 15 and test suite, and the tire tool is set
Put on slide unit, the tire tool connects actuator by connecting rod；The test suite includes Rear secondary frame for vehicle 1, rear spring arm
2nd, rear trailing arm 3, rear upper swing arm 4 and rear lower swing arm 5, the Rear secondary frame for vehicle 1, rear spring arm 2, rear trailing arm 3, rear upper swing arm 4 with
And rear lower swing arm 5 is installed on automobile body clamp.In the technical scheme, Rear secondary frame for vehicle 1, spring arm 2, rear trailing arm 3, rear upper swing arm
4th, rear lower swing arm 5, this five connecting rods are called five connecting-rod separated suspensions, and its effect is to provide the controling power of multiple directions, is made
Tire have the suspension frame structure of relatively reliable driving trace there is provided it is more accurate, position more accurate wheel alignment parameter.
By taking five linkage suspensions for often applying to trailing wheel as an example, wherein, main control arm can play a part of adjusting trailing wheel toe-in, to carry
The friction of high vehicle run stability, effectively reduction tire.Multi link suspension can realize the optimum position of castor, significantly
Degree reduces the fore-and-aft direction power from road surface, so as to improve the ride comfort and comfortableness when accelerating and braking, also ensure that simultaneously
The stability of straight-line travelling, because being stretched by helical spring or compressing caused wheel transversal displacement very little, is not easily caused non-
Straight-line travelling.In turn inside diameter or braking, multi link suspended structure can make trailing wheel form positive toe-in, improve the control of vehicle
Performance, when the situation multi link for reducing understeer is suspended on contraction can adjust automatically camber angle, toe-in angle and obtain trailing wheel
Obtain steering angle necessarily.Active accommodation wheel when being suspended on compression by enabling to the constraint angle design for connecting motor point
Positioning, this design freedom is very big, and matching can be done directed entirely to vehicle and adjustment grabs ground to play tire to greatest extent
Power is so as to improve the manipulation limit of vehicle.
Operation principle：Referring to Fig. 1-Fig. 4, the technical scheme is by designing the vehicle body work consistent with body of a motor car installation dimension
Fill tool, carry out Set and Positioning automobile chassis part, then by load suffered in simulating vehicle normal driving process with
Excitation, the test that reliability and durability are carried out to chassis part is verified.Ground so as to the chassis part of split type of dispatching a car
Study carefully and analyze, verify its service life and reliability.Test-bed structure described in the technical scheme is as shown in figure 1, this implementation
The part that example is tested, including Rear secondary frame for vehicle 1, spring arm 2, rear trailing arm 3, rear upper swing arm 4, rear lower swing arm 5.Test the work of application
Filling tool includes automobile body clamp 11, tire tool 12, slide unit 13, connecting rod 14, actuator 15 etc..The chassis part of vehicle is installed real
Entrucking state in border is arranged on automobile body clamp；By the chassis of tire tool and slide unit simulating vehicle in the process of moving by
Power state；It is specific as follows by actuator to vehicle chassis part imposed load and excitation：
1）Stress of the test mode of chassis part using slide unit form come simulating vehicle on normal road when form
With excitation state；2）The structure type of automobile body clamp simulates the entrucking state of time of day low bottom-disc part, without mounted in reality
Tested on car；Vehicle is substituted with tool fixture, you can save experimental test cost；
3) structure type matched with five company's phase independent suspensions；
Referring to Fig. 2, Fig. 3, vehicle chassis part is by A, B, C, D in figure, and 8 tie points are connected to vehicle body, simulates bottom
Virtual condition of the disk with automobile；
4）Referring to Fig. 4, the motor pattern of above-mentioned knot platform framework body；
By oil pressure plus the device that shakes along vehicle forward direction, move forward and backward.What is received among simulating vehicle traveling process is vertical
To power excitation and load.
The technical scheme can subtract the development cost of vehicle chassis part significantly, while can substantially reduce later stage production by experiment
There is the situation failed in volume production process in product, and the reliability and stability of product are can verify that by experiment and test.Simultaneously can
The research and development of products of enterprise itself and power of test.
It should be noted that above-described embodiment is only preferred embodiment of the present utility model, not for limiting this
The protection domain of utility model, the equivalent substitution or replacement made on the basis of above-mentioned technical proposal, belongs to this practicality
New protection domain.
