Description
Technical field
The present invention relates to automobile tire tests, and in particular to a kind of fixation device for tire stiffness test.
Background technique
Tire is the unique parts for connecting vehicle and ground, and very crucial effect is played on automobile.Tire should prop up
The impact supportted car body, mitigate road surface, will also play traveling and system by the frictional force and brake force for contacting generation between ground
Dynamic effect.The rigidity of tire is an important performance indexes of tire, and rigidity oversize tyre ground shock power is bigger, tire with
The problem of frictional force on ground reduces, and comfort is brought to reduce with braking distance increase.Branch of the too small tire of rigidity to car body
Support is insufficient, and the frictional force on tire and ground increases, and control stability is caused to reduce the problem of oil consumption increases.
In order to detect whether the rigidity of tire meets design requirement, often rigidity test is carried out to tire.It is carrying out just
When degree test need that tested tire is fixed.
CN105445042A discloses a kind of tyre tester comprising rack, telescoping mechanism, movable head, driving braking
Device and road surface simulation device, are equipped with supporting table in rack vertically, and movable head is set to the opposite side of supporting surface of supporting table, drive
Dynamic brake apparatus is installed on inside movable head, and tire to be tested is installed on the end of movable head；Between movable head and supporting table
If there are three telescoping mechanisms circumferentially, and the both ends of each telescoping mechanism are connect with movable head and supporting table respectively, are stretched
Device for measuring force for measuring its axial force and the first displacement detector for measuring its stroke are installed in mechanism.It should
The side-to-side movement of tire, lateral deviation movement and roll motion, less component energy can be realized using three telescoping mechanisms in invention
Enough carry out the test of mechanics of tire characteristic.
But when being tested using foregoing invention for various sizes of tire, need to make to support using different equipment
The size of the height and tire of platform and road surface simulation device is adapted.
Summary of the invention
The object of the present invention is to provide a kind of fixation devices for tire stiffness test, can satisfy different size of wheel
The requirement of tire and different experimental facilities.
To realize the above-mentioned technical purpose, the scheme that the present invention uses is as follows:
A kind of fixation device for tire stiffness test, the tire including installation pedestal and for fixing tire to be tested
Mounting structure, the installation pedestal has horizontally disposed bottom plate and the vertical guiding trestle being fixed on bottom plate, described to lead
Guide groove from top to bottom is offered on bracket；The tire mounting structure includes mounting disc and is fixed on leading in mounting disc
To block, tire to be tested is mounted in mounting disc；The guide pad is located in guide groove, and the width and guide groove of guide pad
It is of same size.
The guide groove it is opening up.
The cross section of the guide pad is in rectangle.
The mounting disc is rounded, and the guide pad is fixed on the center of mounting disc.
The fixed form of the bottom plate and guiding trestle is to weld, and the fixed form of the guide pad and mounting disc is weldering
It connects.
The upper surface of the bottom plate offers the bar shaped installation through-hole for connecting with static pressure test bed.
For installing the tire installation through-hole of tire to be tested there are five being opened up in the mounting disc.
The beneficial effects of the present invention are: (1) due to test when, guide groove limit movement of the tire on bottom plate and
It rolls, can achieve the purpose that fixed；(2) since guide pad is not fixed, guide pad can be caught in any in guide groove
Position, therefore, no matter the present invention, which can be used, in the tire of which kind of size is fixed, and avoiding various sizes of tire must be using not
The problem of with fixed device；(3) it is directed to different tires, this fixation device can be used without adjustment；(4) due to installation pedestal
Have the characteristics that on light and bar shaped installation through-hole that threaded fastener can be used in any position to fix with other equipment, meet
The installation requirements of different pressures testing machines；(5) the configuration of the present invention is simple, it is at low cost, it is easy to use.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the structural schematic diagram that tire to be tested is mounted in the present invention.

Specific embodiment
In order to make those skilled in the art that the present invention may be better understood, with reference to the accompanying drawings and examples to this hair
Bright technical solution further illustrates.
A kind of fixation device for tire stiffness test, the wheel including installation pedestal 1 and for fixing tire 3 to be tested
Tire mounting structure 2, it is characterised in that: there is the installation pedestal 1 horizontally disposed bottom plate 11 and vertical to be fixed on bottom plate 11
On guiding trestle 12, guide groove 14 from top to bottom is offered on the guiding trestle 12；The tire mounting structure 2 includes
Mounting disc 22 and the guide pad 21 being fixed in mounting disc 22, tire 3 to be tested are mounted in mounting disc 22；The guide pad 21
In guide groove 14, and the width of guide pad 21 and guide groove 14 is of same size.Mentioned here is of same size, with
Subject to guide pad can be placed in clamping groove and cannot move along its width direction.
The guide groove 14 it is opening up, guide pad 21 can directly be inserted from above into guide groove 14 and cooperate with it, this
Mode is easy to operate.
The cross section of the guide pad 21 is in rectangle, can avoid the rotation of tire 3 to be tested completely.
The mounting disc 22 is rounded, and the guide pad 21 is fixed on the center of mounting disc 22.
The fixed form of the bottom plate 11 and guiding trestle 12 is welding, the fixation side of the guide pad 21 and mounting disc 22
Formula is welding.
The upper surface of the bottom plate 11 offers the bar shaped installation through-hole 13 for connecting with static pressure test bed.Pacify in bar shaped
Any position can be used threaded fastener and fix with other equipment on dress through-hole 13.
For installing the tire installation through-hole 23 of tire 3 to be tested there are five being opened up in mounting disc 22.
When carrying out tire stiffness test, tire 3 to be tested must be first fixed, including the following steps: step 1 will install base
Seat 1 is installed on static pressure experimental bench by bar shaped installation through-hole 13 with bolt；Step 2, bolt will by tire installation through-hole 23
Tire mounting structure 2 is attached with tire 3 to be tested；Guide pad 21 is caught in guide groove 14 by step 3；Step 4 is used
Experiment compressing head 4 treats test tire 3 and carries out static pressure rigidity test.
In test, guide groove 14 limits movement and rolling of the tire 3 to be tested on bottom plate 11, can reach fixed
Purpose.Although not fixed between installation pedestal 1 and tire mounting structure 2, according to the stress condition of tire 3 to be tested
Analysis, tire 3 to be tested will not occur mobile and roll.
Since guide pad 21 is not fixed, in above-mentioned steps three, guide pad 21 can be caught in appointing in guide groove 14
One position, therefore, no matter the present invention, which can be used, in the tire of which kind of size is fixed, and avoiding various sizes of tire must use
Difference fixes the problem of device.And it is directed to different tires, this fixation device can be used without adjustment, and structure is simple, at
This is low, easy to use.Meanwhile the installation pedestal 1 that uses of the present invention have the characteristics that it is light, can in conjunction with bar shaped installation through-hole 13
Meet the installation requirements of different pressures testing machine.
