Technical field
The present invention relates to field of vehicle part detection, and in particular to commutator running clearance test table and test side
Method.
Background technology
Auto steerer is component part important in automobile chassis system, and automotive steering is for keeping or changing
Become the mechanism of vehicle traveling direction, in motor turning when driving, also to ensure coordinated angle relation between each deflecting roller.It drives
The person of sailing makes automobile be maintained at straight line or turning motion state or makes above two motion state phase by manipulating steering
Mutually conversion.
Because of the importance of automobile steering system, rational space layout and reliable and stable transmission are of crucial importance
's.Currently in order to improving the comfort of passenger, domestic truck develops towards car direction, and steering employs and sedan-chair
The identical rack and pinion steering gear of vehicle.As shown in Figure 1, what domestic truck was equipped with is mostly cab over engine, steering column 2
In the front of steering gear 6, steering column 2 can not directly be connect with steering gear 6, need to pass through between steering column 2 and steering gear 6
A kind of commutator 4 realizes the change of transmission direction, in this way, the rotation of steering wheel 1 can just pass to steering column 2, turn successively
It is final to drive vehicle wheel rotation or keep linear rows to tubing string lower drive shaft 3, commutator 4, commutator transmission shaft 5 and steering gear 6
It sails.
Parts running clearance is to influence the important factor in order that driver's subjectivity is driven in automobile steering system, such as
Fruit steering parts running clearance crosses conference and causes the feeling for having looseness in steering procedure, is brought to driver a kind of uneasy nervous
Feeling.Driving fatigue can be if things go on like this caused, is susceptible to traffic accident.The size of running clearance is generally weighed with angle.

Specific embodiment
With reference to figure 2, in the commutator running clearance test table of the present embodiment, commutator branch is installed on bottom plate 7
Support arrangement 8, riser 9 are installed with the first spline housing 10 on riser 9.More specifically, commutator support device 8 is opened for top
There are more pillars of threaded hole.
With reference to figure 3, in the commutator running clearance test table of the present embodiment, using one independently of bottom plate 7
Reference test bar 11, the center of reference test bar 11 is equipped with the second spline housing 12, end positions are mounted on hook 13.In the application
In, reference test bar 11 refers in particular to homogeneous rod piece, and center is at the 1/2 of its length and is its barycenter.And two 13 installations of hook
Represent that two hooks 13 are equidistant with center in end positions.
First spline housing 10, the second spline housing 12 are opening spline housing.
With reference to figure 4, commutator 4 to be tested is had been installed on commutator running clearance test table.In bottom plate 7
On displacement measuring device 18 is also equipped with by stent 17, displacement measuring device 18 can use electronic type or mechanical hundred
Divide table, amesdial.Commutator 4 is supported in commutator support device 8 and passes through bolt 14 and fastens, and the first spline housing 10 is with changing
Spline fitted, which is formed, to the input shaft of device 4 and passes through bolt 15 adjusts the openings of sizes of the first spline housing 10 so as to make the first spline
Set 10 and the input shaft of commutator 4 form tight fit.The output shaft 19 of the second spline housing 12 and commutator 4 of reference test bar 11 is spent
Key coordinates, and passes through bolt 16 and adjust the openings of sizes of the second spline housing 12 so as to clamp output shaft 19.Here, input shaft with it is defeated
Shaft is relative concept, might not represent directions of torque transfer of the commutator 4 in real work, the two is during the test
It can exchange.
With reference to figure 5, for clarity, the figure omits 7 grade devices of bottom plate.The center of reference test bar 11 be o, the second spline
The barycenter of set 12 is in o in a vertical straight line.During the test, the gauge head of displacement measuring device 18 needs engaged test
At the separate center o of bar 11, the gauge head of displacement measuring device 18 and the contact position of reference test bar 11 and center o away from
From labeled as R.In test, the gauge head of displacement measuring device 18 needs 13 positions of corresponding hook of 11 one end of engaged test bar
Place.
With reference to figure 6, it is using the step of above device realization commutator running clearance test method：
Commutator 4 is supported in the commutator support device 8 of commutator running clearance test table, it is tight with bolt 14
Gu.
By the input shaft spline fitted of the first spline housing 10 and commutator 4 and pass through bolt 15 and clamp, by the second spline housing
12 with the output shaft spline fitted of commutator 4 and passing through bolt 16 and clamping.
On the hook 13 that weight 20 is hung over to 11 right end of reference test bar, required rotatory force is applied with the weight of weight itself
Square.For example, when the rotating torque applied when tested is ± 1Nm so that the product of the arm of forces of the mg with linking up with distance o points is equal to
1Nm, wherein m are the quality of weight 20, and g is acceleration of gravity.
At the separate center o for making the gauge head engaged test bar 11 of displacement measuring device 18, displacement measuring device is recorded
18 reading S1.
Weight 20 is removed and is then hung up on the hook 13 of 11 left end of reference test bar, records the reading of displacement measuring device 18
S2。
Calculate the poor h=of reading S1 and S2 | S1-S2 |, h is the shift motion of the gauge head of displacement measuring device.
With reference to figure 7, due to the test angle very little of commutator steering gap, classification is commonly reached not, therefore can use
Approximate right angle triangle as shown in Figure 7 carries out trigonometric function conversion, and commutator running clearance angle is：A=arctan (h/
R).By adjusting the length of R, such as the length of adjustment reference test bar 11 or the gauge head and the test that adjust displacement measuring device 18
The contacting points position of bar 11 can adjust measuring accuracy.As R=100mm, stage accuracy can reach 0.34 ', work as R
During=200mm, precision can reach 0.17 '.As it can be seen that in the present embodiment, by mechanical measuring device and method, with reference to
Trigonometric function can calculate the running clearance of commutator 4 indirectly, and measuring accuracy can be adjusted by the length of reference test bar
Whole, of low cost without high-precision angular transducer, applicability is stronger.
Although the present invention is described with reference to above example, the present invention is not limited to above-described embodiment,
And only limited by claim, those of ordinary skill in the art can easily modify and change to it, but not from
The essential idea and range of format invention.
