Compared with prior art, there is following technique effect in the present invention: measuring process is convenient and swift, by generating laser, reflective mirror, dash receiver and angle dial, the angle between left and right gage beam is directly reflected, this angle is exactly described toe-in angle, then carries out vehicle adjustment according to toe-in angle; This is simple in structure simultaneously, and cost is low.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with Fig. 1, the present invention is described in further detail.
Consult Fig. 1, a kind of toe-in of automobile angle measuring device, comprise left socle 10, right support 20, described left socle 10 comprises the left gage beam 11 of direct rod shape and is arranged on the generating laser 12 on left gage beam 11, dash receiver 13, on dash receiver 13, be provided with mark line 131, described right support 20 comprises the right gage beam 21 of direct rod shape and is arranged on the reflective mirror 22 on right gage beam 21, angle dial 23, reflective mirror 22 can rotate around axle 221, the angle that angle dial 23 rotates for recording reflective mirror 22, the light that described generating laser 12 is launched is reflected back on dash receiver 13 through reflective mirror 22, on the shaft of described left and right gage beam 11,21, being provided with alignment unit snaps to left and right support 10,20 on vehicle wheel rim.The wheel rim is here exactly the edge of wheel hub, in the time that left and right gage beam 11,21 is aligned on wheel hub, the toe-in angle of wheel hub is not 0 o'clock, make left and right gage beam 11,21 not parallel, and the angle between left and right gage beam 11,21 is exactly so-called toe-in angle, this device converts toe-in angle to angle between left and right gage beam 11,21 exactly.
As preferred version of the present invention, described mark line 131 arranges along vertical, and the laser of generating laser 12 penetrates direction and mark line 131 and is positioned at the same face and this face length direction perpendicular to left gage beam 11; Described axle 221 is along vertical layout and vertical with the length direction of right gage beam 21, and the card of described angle dial 22 is positioned at surface level, after arranging like this, and can be more accurate.It should be noted that the angle that the laser here penetrates direction and mark line 131 should be slightly less than 90 °, shown in Fig. 1 is exactly to be slightly less than 90 °, and its laser being reflected back drops on dash receiver 13; If equal 90 °, the route that laser reflects through reflective mirror 22 overlaps with transmitting route, is not easy to find out the laser position returning.
Its detailed measurements step is as follows: (A) before measurement, this device and vehicle to be measured are placed on a smooth bottom surface; (B) by left and right gage beam 11,21 parallel placements, adjust reflective mirror 22, make the laser reflecting back just in time be positioned at mark line 131 places on dash receiver 13; (C) left and right gage beam 11,21 is snapped on wheel rim, if toe-in angle is not 0, the laser that reflective mirror 22 reflects back can not drop on mark line 131 places, entering step D adjusts, if toe-in angle is 0, the laser that reflective mirror 22 reflects back also can drop on mark line 131 places, does not need to regulate; (D) again adjust reflective mirror 22, make the laser reflecting back drop on mark line 131 places, the angle that this reflective mirror 22 rotates is the angle between left and right gage beam 11,21, is also toe-in angle.
The angle of rotating in order directly to read reflective mirror 22, angle dial 23 is indispensable, but the set-up mode of angle dial 23 is various.In the present embodiment, preferably, described angle dial 23 is fixedly connected with reflective mirror 22, and angle dial 23 is synchronizeed and rotated around axle 221 with reflective mirror 22; On described right gage beam 21, be provided with pointer 211, the length direction of pointer 211 is consistent for reading angular information with the radial direction of angle dial 23 cards.Arrange after pointer 211, in step B, after reflective mirror 22 is adjusted, pointer 211 is pushed to 0 ° of position of angle dial 23; In step D, while rotating reflective mirror 22, because pointer 211 is fixed on right gage beam 21, not along with reflective mirror 22 rotates, but angle dial 23 is synchronizeed rotation with reflective mirror 22, the angle that angle dial 23 turns over is exactly the angle that reflective mirror 22 turns over, and can directly read out, very convenient.
Further, for the ease of placing left and right gage beam 11,21, on described left and right gage beam 11,21, be respectively arranged with left and right supporting leg 14,24 and be convenient to place described left and right support 10,20, in the present embodiment, left branch leg 14 forms T font with left gage beam 11.
The set-up mode of alignment unit is various, as preferred version of the present invention: the alignment unit arranging on described left gage beam 11 is made up of two L-shaped left-justify bars 15, two left-justify bars 15 are arranged along the length direction interval of left gage beam 11, two left-justify bar 15 spacing are adjustable, left-justify bar 15 places face perpendicular to the bar length direction of left gage beam 11; The alignment unit arranging on described right gage beam 21 is made up of two L-shaped Right Aligns bars 25, two Right Aligns bars 25 are arranged along the length direction interval of right gage beam 21, two Right Aligns bar 25 spacing are adjustable, Right Aligns bar 25 places face perpendicular to the bar length direction of right gage beam 21.Distance between two left-justify bars 15 or two Right Aligns bars 25 is adjustable, is in order to adapt to different vehicle.
Further, described left-justify bar 15 is made up of first and second straight-bar 151,152, first and second straight-bar 151,152 is perpendicular to one another and is described L shaped, the first straight-bar 151 be connected with left gage beam 11 and the bar length direction of the first straight-bar 151 parallel with mark line 131; Described Right Aligns bar 25 is made up of third and fourth straight-bar 251,252, and third and fourth straight-bar 251,252 is perpendicular to one another and is described L shaped, the 3rd straight-bar 251 be connected with right gage beam 21 and the bar length direction of the 3rd straight-bar 251 parallel with axle 221; First and third straight-bar 151,251 is equal in length, and second, four straight-bars 152,252 are equal in length.The distance that the first straight-bar 151 of the left-justify bar 15 of close dash receiver 13 is fixed on left gage beam 11 and between this first straight-bar 151 and mark line 131 is L1; The distance that the 3rd straight-bar 251 of the Right Aligns bar 25 of close reflective mirror 22 is fixed on right gage beam 21 and between the 3rd straight-bar 251 and axle 221 is L2, and described L1 is consistent with L2 numerical value.One of them left and right alignment rod 15,25 is separately fixed on left and right gage beam 11,21, only need to regulates the position of another left and right alignment rod 15,25, in the time regulating, meeting is more laborsaving like this.
