Description
Technical field
The present invention relates to automobile chassis vibration and noise test technical field, be specifically related to a kind of passenger car steering wheel monomer mould measurement
Device.
Background technology
Along with car comfort requirement is improved constantly by user vehicle, auto NVH is increasing by numerous auto vendors
Pay attention to, and directly vibration with the steering wheel of human contact is an emphasis of auto NVH concern.Steering wheel monomer mode pair
Steering mode produces impact, thus affects the level of vibration of steering wheel.Therefore, steering wheel monomer mode the other side is measured to dish
Vibration control is significant.
The test of vehicle steering monomer needs a kind of fixture, on the one hand can be applicable to the peace of polytype passenger car steering wheel
Dress, the beneficially excitation of power hammer；On the other hand make steering wheel be in ground state, it is ensured that the accuracy of test, to ensure examination simultaneously
The standardization tested and concordance.
Steering mode is only calibrated by major part automaker at present, with targeting device (such as LMS) directly to turning
Test to the mode of system, it is not necessary to frock, steering wheel monomer mode is not calibrated, there is steering mode not
Risk up to standard.
Summary of the invention
It is an object of the invention to provide the device of a set of measurement direction dish monomer mode, its object is to measurement direction dish loose pattern
State.
Passenger car steering wheel monomer mould measurement device of the present invention includes that base, steering wheel mounting bracket, base fix spiral shell
Bolt, base fix nut, pad and steering wheel clamp nut, and described base fixes bolt by base and base fixes nut admittedly
Being scheduled on the chute of floor, steering wheel mounting bracket is fixed on base, equipped with the steering wheel fastening spiral shell installing fastening direction dish on it
Female.
Further, the position that described steering wheel mounting bracket is connected with steering wheel is spline structure, mutually embedding with the spline of steering wheel
Close.Steering wheel mounting bracket is also provided with steering wheel fastening gasket, coordinates steering wheel clamp nut that fastening direction dish is installed.
The present invention is applicable to measurement direction dish monomer mode, and in order to improve measuring accuracy, base mounting orientation is fixed, ground connection mode
Not less than 1000Hz, steering wheel setting angle is constant, it is ensured that the standardization of test and concordance, gets rid of steering wheel established angle
Degree and the impact of floor installation rigidity, also eliminate the impact that test result is produced by anthropic factor.
Compared to the prior art, the present invention has the following advantages:
1, use this frock can steering wheel monomer be calibrated, reduce the risk that steering mode is the most up to standard.
2, this device, simple in construction, easy to operation, fixing mounting means ensure that the reliability of test is with accurate
Property.
This device is used for automobile production producer, can calibrate steering wheel monomer mode, and the beneficially target of steering sets
Determine and decompose.This device is used for steering wheel manufacturer, can detect the situation up to standard of steering wheel, thus improve the qualified of product
Rate.
Accompanying drawing explanation
Fig. 1 is steering wheel monomer mould measurement device decomposing schematic representation；
Fig. 2 is base and floor chute scheme of installation；
Fig. 3 is that steering wheel encourages schematic diagram.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
Fig. 1 is passenger car steering wheel monomer mould measurement device decomposing schematic representation of the present invention, including base 1, is fixed on
2, two bases of steering wheel mounting bracket on base fix 3, two bases of bolt, and to fix nut 4, pad 5, steering wheel tight
Gu nut 6 and floor chute 7.Base 1 fixes bolt 3 by base and base is fixed nut 4 and is fixed on floor chute 7
On, floor chute 7 is close in base 1 bottom surface, and base 1 thickness is 30mm.Steering wheel mounting bracket 2 is fixed on base 1
On, steering wheel mounting bracket 2 is that many steps are cylindric, and its height is 80mm.Equipped with installing tightly in steering wheel mounting bracket 2
Gu the steering wheel clamp nut 6 of steering wheel and steering wheel fastening gasket 5.The position being connected with steering wheel to dish mounting bracket 2
For spline structure, with the spline tabling of steering wheel.
Method of testing:
First, base 1 is arranged on floor chute 7, makes base groove opening and floor chute register.
Further, as shown in Figures 2 and 3, from both ends open, base is fixed bolt 3 and load opening, rotate and make it block
Tightly, then loading onto base and fix nut 4, tightened with torque spanner, its value is 200N mm.
Further, steering wheel is installed to steering wheel mounting bracket 2, rotates and make spline between the two agree with completely.
Further, steering wheel mounting bracket is loaded onto pad 5, screw on steering wheel clamp nut 6, twisted with torque spanner
Tightly, its value is 100N mm.
Finally, as it is shown on figure 3, use mould measurement equipment (such as LMS) that steering wheel monomer mode is tested, firmly
The both direction (Z-direction and Y-direction) of hammer excitation orientation dish respectively, obtains mode and the vibration shape of steering wheel.
