After the fatigue life testing apparatus is adopted, the development period of the passenger vehicle product can be shortened and the development cost is reduced. The fatigue life testing apparatus is novel and practical, has scientific and reasonable structure and is simple and convenient to operate. The test of the fatigue life of the hub rack of the passenger vehicle is effectively realized. The gap of the test of the hub rack of the passenger vehicle is filled up. The fatigue life testing apparatus has great significance for shortening the development period and reducing the development cost for the passenger vehicle product.
Description
Technical field
The utility model passenger car wheel hub rack fatigue life test apparatus belongs to the automobile test field.
Background technology
Automotive engineering development advanced person's country because of wheel hub has significant impact to traffic safety, verifies so its life-span need be passed through bench test in exploitation passenger car process.This last vapour technique center and FAW-Volkswagen do not have passenger car wheel hub rack fatigue life test apparatus, and automobile industry is not collected the data of relevant passenger car wheel hub rack fatigue life test apparatus yet at home.It is reported that the wheel hub rack fatigue durability test of FAW-Volkswagen car system carries out in Germany.
Summary of the invention
The purpose of the utility model is to provide a kind of passenger car wheel hub rack fatigue life test apparatus, and it can shorten the passenger car product development cycle, reduces cost of development, Nover practical, convenience scientific and reasonable for structure, simple to operation.
The technical scheme of the utility model is achieved in that passenger car wheel hub rack fatigue life test apparatus; Install and fix part, loading section and drive part by testpieces are formed; It is characterized in that: the part that installs and fixes of testpieces is assembled into test assembly by testpieces and former automobile-used hub bearing, wheel hub, steering knuckle, spoke and vibration damper; Wherein vibration damper is connected with the fixed support crossbeam through spherical hinge, and the knuckle arm place is connected with drag link with cross-bar connector through real vehicle, and the drag link other end is connected through the upright beam of spherical hinge and fixed support; Control arm ball pin one side is connected with steering knuckle, and opposite side is connected through the upright beam of bearing pin and fixed support; Loading section is connected by testpieces hub and spokes bolt; Loading circle loads on the axle with integrally welded being installed in of spoke; Load between axle and the loading arm and be assembled into the loading arm assembly through bearing; Be connected with the spring-loaded device with connecting pin through transmission rod, the angle between spring-loaded device axis and the testpieces hub axis is 45 degree; Transmission shaft one end of drive part is connected with the testpieces wheel hub, and the other end links to each other with motor.
The good effect of the utility model is that it is scientific and reasonable for structure, cost is low, convenience simple to operation; Realized the test in passenger car wheel hub rack fatigue life-span effectively; Filled up the blank of passenger car wheel hub bench test, to the passenger car product development shorten the cycle, reducing cost has very big meaning.
Description of drawings
Fig. 1 passenger car is with the local enlarged diagram of wheel hub rack fatigue life test apparatus.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further description: as shown in Figure 1; Passenger car wheel hub rack fatigue life test apparatus; Install and fix part, loading section and drive part by testpieces are formed; It is characterized in that: the part that installs and fixes of testpieces is assembled into test assembly by testpieces and former automobile-used hub bearing 5, wheel hub 6, steering knuckle 4, spoke 7 and vibration damper; Wherein vibration damper is connected with fixed support 3 crossbeams through spherical hinge, and steering knuckle 4 arm places are connected with drag link with cross-bar connector through real vehicle, and the drag link other end is connected with fixed support 3 upright beams through spherical hinge; Control arm ball pin one side is connected with steering knuckle 4, and opposite side is connected with fixed support 3 upright beams through bearing pin; Loading section is connected with spoke 7 bolts by testpieces wheel hub 6; Loading circle 8 loads on the axle 9 with spoke 7 integrally welded being installed in; Load between axle 9 and the loading arm 10 and be assembled into the loading arm assembly through bearing 11; Be connected with spring-loaded device 14 through transmission rod 13 usefulness connecting pins 12, the angle between spring-loaded device 14 axis and testpieces wheel hub 6 axis is 45 degree; Transmission shaft 2 one ends of drive part are connected with testpieces wheel hub 6, and the other end links to each other with motor 1.
As shown in Figure 1; The mounting part of testpieces divides the practical set situation according to entrucking; The steering knuckle 4 of testpieces wheel hub 6 and former car, hub bearing 5 etc. are assembled into test assembly, point of fixity imitation real vehicle connected mode administration of fixed on the fixed support 3 of test unit.
Loading section adopts testpieces wheel hub 6 to be connected with spoke 7 usefulness real vehicle wheel bolts with the real vehicle dress, and purpose is that make can approaching automobile-used actual condition by the stressing conditions of test specimen.In order to solve the difficulty of loading, be designed with and load circle 8, load circle 8 and spoke 7 integrally welded, load circle 8 and be installed in and load on the axle 9.Load between axle 9 and the loading arm 10 and be assembled into assembly, form the loading arm assembly through bearing 11.Angle when requiring to install between spring-loaded device 14 axis and testpieces wheel hub 6 axis is 45 degree.And the intersection point of transmission rod 13 axis of spring-loaded device and loading arm (being the central point of connecting pin 12) should be at the ground contact point place.Through this load and execution mechanism, realize loading axle loading arm when rotating and to realize that to wheel hub becoming angle with hub axis is the thrust of 45 degree with wheel hub is synchronous.And the load(ing) point of test load is the ground contact point of whole-vehicle design parameters regulation.
Drive part adopts former automobile-used transmission shaft 2 one ends to be connected with testpieces wheel hub 6, and the other end links to each other with motor 1, accomplishes the driving function of this test unit.
Should testpieces wheel hub 6 and former car steering knuckle 4, hub bearing 5 etc. be assembled into test assembly before using this device to make an experiment; And be fixed on the fixed support 3 of test unit warranty test spare wheel hub 6 axis horizontal through steering knuckle 4 imitation real vehicle connected modes.Because of transmission shaft 2 one ends are connected with motor 1; The other end links to each other with testpieces wheel hub 6, and testpieces wheel hub 6 is connected with former car wheel spoke 7 through wheel bolt again, is welded as a whole because of spoke edge and loading circle 8 again simultaneously; So during test; Through 1 rotation of Frequency Converter Control stepless speed-regulating motor, drive transmission shaft 2 rotations, motoring ring test part wheel hub 6 and 8 rotations of loading circle.Simultaneously spring-loaded device 14 applies the test static load that becomes 45 degree with its axis (this load be equivalent to vertical load and side direction carry with joint efforts) through 10 pairs of testpieces wheel hubs 6 of loading arm.When testpieces wheel hub 6 was driven in rotation, the test static load was changeless, and testpieces wheel hub 6 will receive the bending load of alternation.Motor 1 is rotation continuously under the regulation rotating speed, has then realized the test of wheel hub flexible life.
