Accompanying drawing explanation
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.In the drawings:
Fig. 1 has shown according to wheel brake dragging moment measuring device of the present utility model.
In the accompanying drawings, not according to actual scale.
Embodiment
Fig. 1 has shown according to wheel brake dragging moment measuring device 20 of the present utility model.As shown in the figure, this measurement mechanism 20 comprises mounting disc 7, the torque spanner 11 that be fixedly installed on mounting disc 7 centers and the data transducer 12 fixed with wheel 1 close coupled type to be measured.Mounting disc 7 is for example circular mounting disc.
The wheel fixed form of current most of car is that bolt is fixed.In a preferred embodiment, by claw 14, mounting disc 7 is fixedly attached on the hold-down nut 2 of wheel 1, claw 14 comprises claw body 3 and cutting ferrule 4, wherein claw body 3 is for being stuck in hold-down nut 2, cutting ferrule 4 is enclosed within on claw body 3, for tightening up claw body 3, makes it be fixed on vehicle wheel fixing nut 2.For example on claw body 3, screw hole is set, on cutting ferrule 4, hole is set, can utilize trip bolt 6 claw 14 to be connected together with mounting disc 7 with the hole on described cutting ferrule 4 through pad 5.
Because the specification of the nut 2 of Wheel set bolt is mostly outer-hexagonal nut, model is divided into tri-kinds of M10, M12 and M14 more, so the size of claw 14 corresponds to
with
three kinds.The quantity of the hold-down nut 2 of single wheel is 3 to 5, so the quantity of claw body 3 and cutting ferrule 4 is consistent with the quantity of nut 2.
As shown in Figure 1, be provided with groove 8 in mounting disc 7, preferred groove 8 is long and narrow groove, and its flute length direction, along the radial direction setting of mounting disc 7, is used for meeting the distribution of the wheel clamp nut 2 with different radial dimensions.A groove 8 is set for common groove, the quantity of the clamp nut 2 of the wheel 1 that foundation is different is 3 to 5, corresponding groove 8 is that 3,4,5 equal angles are distributed in mounting disc 7, so 10 grooves 8 are set in mounting disc 7, and just to meet clamp nut quantity be 3 to 5 needs.For being connected with wrench torque 11, there is the center pit 13 passing for bolt 9 at mounting disc 7 centers.The mounting disc 7 obtaining by such setting has versatility, meets the distribution with different radial dimensions and the hold-down nut 2 varying number apart from wheel 1 center.
Torque spanner 11 is elongated rod shape, is fixedly installed data transducer 12 on it, and for example data transducer 12 is wheel speed sensors.Utilize switching sleeve 10 that torque spanner 11 is arranged to mounting disc 7 centers, one end of switching sleeve 10 is arranged on the bolt 9 through mounting disc 7 center pits 13, and the other end is fixedly installed on torque spanner 11.
To before the dragging moment and measure of wheel 1, first guarantee that variator is in neutral position state, then car load is given rise to and is applicable to the height handled with lifting machine, also can adopt lifting jack, it has advantages of for single wheel measures.Vehicle need to be met by the height of lifting, in operation, and can be from top to bottom or rotating-wheel from left to right.
Claw body 3 is arranged on vehicle wheel fixing nut 2, and in installation process, the top of claw body 3 will fit to the bottom of hexagonal nut 2, and claw body 3 is in place, otherwise can not guarantee that mounting disc 7 is coaxial with wheel 1, causes the result of measurement inaccurate.
Middle bolt 9 is fastened on mounting disc 7 center pits 13.The quantity of corresponding claw body 3 is selected the groove 8 in mounting disc 7, cutting ferrule 4 is enclosed within on claw body 3, trip bolt 6 is through the hole on pad 5 and cutting ferrule 4, be anchored in the screw hole of claw body 3, while making by trip bolt 6 tractive claw body 3, tightening up claw body 3 is fixed on vehicle wheel fixing nut 2 it, and mounting disc 7 is fixedly connected with claw 14, after fixedly completing, requires mounting disc 7 and wheel 1 in coaxial state.
One end of switching sleeve 10 is connected on the middle bolt 9 that is fixed on mounting disc 7 centers, the other end is connected with torque spanner 11.
Before measuring, wheel 1 to be measured is rotated to several weeks, make between wheel 1 and axle evenly lubricated.Utilize the principle of equalising torque, moment of torsion be added on main shaft wheel 1 is just rotated, now to the moment of wheel shaft with drag moment size and just equate, opposite direction.Therefore, operating torque spanner increases dynamics gradually by stationary state, maintenance is by the static critical dynamics uniform rotation wheel to motion state, and record is fixedly mounted on the data that the data transducer 12 on torque spanner 11 shows simultaneously, and this numerical value is the moment that drags of single wheel.But these data are measured value, have error, for guaranteeing the reliability of numerical value, need to repeatedly measure and then get its mean value (at least three times).
In Fig. 1, shown the wiring layout of wheel brake dragging moment measuring device and wheel to be measured, from figure, do not demonstrate hold-down nut 2 on above-mentioned wheel 1, be fixed on middle bolt 9 in mounting disc 7 and the center pit 13 in mounting disc 7.Due to its structure that is part well known to those skilled in the art and is readily appreciated that, at this, do not provide independently structural drawing.
According to wheel brake dragging moment measuring device of the present utility model, it is simple in structure, and volume has very large reduction with respect to prior art, and therefore measurement application is simple and easy to carry.In addition, when inventor proves data transducer by experiment with the method steady job, when reaching 100km/h, the speed of a motor vehicle can not got rid of, and fixing extremely reliable; Mounting disc and claw adopt simple trip bolt to fix, easy to operate; Claw size can be applicable to most vehicle wheel fixing nut, highly versatile; By special management and simple-to-maintain, can guarantee the serviceable life of quite growing.
The foregoing is only preferred implementation of the present utility model; but the utility model protection domain is not limited to this; any those skilled in the art is in the disclosed technical scope of the utility model; can easily change or change, and this change or change and all should be encompassed in protection domain of the present utility model within.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
