Abstract

The utility model discloses a self-centering hanging frame used for four-wheel alignment. The self-centering hanging frame consists of a handle, a claw, a bolt, a connecting rod, a fixed pin, a tension spring pin, a connecting block, a tension spring and a hanging frame body. The utility model is characterized in that a locating sleeve and a peaking shaft are arranged on the hanging frame body, and can be mutually switched quickly, and the lead screw structure and the guide rod structure in the prior art are replaced by a gear driving mechanism, a connecting rod structure and a slide block structure. The utility model has the advantages that the utility model has three-point synchronous motion location, the location is rapid and accurate, the dimension is stable, the precision is high, the locating sleeve can be switched with the peaking shaft rapidly, and the wheel rim is not damaged.

Description

A kind of four-wheel location self-centering hanger

The utility model belongs to the wheel alignment technical field, especially relates to a kind of four-wheel location self-centering hanger.

At present, the single interior top of the general employing of the hanger that vehicle location is used, the structure of lead screw transmission slender axles guiding, its three-point fix is independent adjustment, fastening, its location watches that by the people rule locatees, artificial error is bigger, locate not accurate enough, though 4 synchronized positioning structures can be synchronous, but it is to pass through lead screw transmission, the slender axles guiding, thereby poor rigidity, 4 definite planes be difficult to guarantee 4 contour, bearing accuracy can not guarantee, and existing locating sleeve and apical axis adopt single structure more, or adopts locating sleeve, maybe need reinstall apical axis, set-up time is long, and different wheel rims need be changed different top cover apical axis alive, so existing technology can not satisfy the needs of vehicular four wheels location.

The purpose of this utility model is to improve the deficiency of prior art and the four-wheel location self-centering hanger that provides a kind of 3 location that are synchronized with the movement, fast and accurate for positioning, dimensionally stable, precision height, locating sleeve and apical axis can change, not damage wheel rim fast.

The purpose of this utility model is to realize like this, a kind of four-wheel location self-centering hanger, be by handle, claw, bolt, connecting rod, fixed pin, tension spring pin, contiguous block, extension spring and hanger body are formed, be characterized in that the hanger body is provided with handle, handle is connected with gear, gear is supported by two copper sheathings, ring flange axial location gear, gear and rolling disc engagement, rolling disc is by bearing and coupling spindle radial location, coupling spindle is connected with rolling disc, and three locating shafts are connected by three connecting rods respectively with locating sleeve, and locating sleeve is connected as a single entity by nut and slide block, the slide block activity is fixed on the hanger body, apical axis is housed in the locating sleeve, and apical axis is connected with handle, and locating sleeve is connected by register pin with apical axis.

In order further to realize the purpose of the utility model protection wheel rim, can also be to be provided with protective sleeve in the termination of locating sleeve.

Compared with the prior art the utility model has following distinguishing feature: the utility model adopts gear to connect slide block mechanism, location action is rapid, accurate, good rigidly, and can guarantee that three-point fix is synchronized with the movement, guaranteed concentricity, apical axis is housed in the locating sleeve and connects by register pin, is can change mutually between locating sleeve and apical axis, can be pursuant to different wheel rims and use locating sleeve or apical axis, save switching time, improved applicable performance greatly.

Below in conjunction with drawings and Examples the utility model is described in further details.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cut-open view of Fig. 1.

Fig. 3 is the B-B cut-open view of Fig. 1.

Fig. 4 is an another kind of structure cut-open view of the present utility model.

Embodiment 1, with reference to Fig. 1, Fig. 2, Fig. 3, a kind of four-wheel location self-centering hanger, be to be arranged with two claws 2 in the centre of hanger body 9, claw 2 is connected by bolt 3 with connecting rod 4, connecting rod 4 is connected with contiguous block 7 by tension spring pin 6, contiguous block 7 is connected on the hanger body 9 by fixed pin 5, tension spring pin 6 is by extension spring 8 tension location, handle 1 is inserted on the contiguous block 7, copper sheathing 28 is contained in hanger body 9 stub bore, mounting hole as four-wheel position finder head and hanger coupling spindle, hanger body 9 is provided with handle 10, handle 10 is connected with gear 12, gear 12 is supported by the copper sheathing 11 and the copper sheathing 13 of front and back, ring flange 14 axial location gears 12, gear 12 is meshing with each other with rolling disc 15, rolling disc 15 is by bearing 27 and coupling spindle 16 radial locations, and coupling spindle 16 is connected with rolling disc 15, and three locating shafts 17 are connected by connecting rod 18 respectively with locating sleeve 25, locating sleeve 25 is connected as a single entity by nut 20 and slide block 22, slide block 22 activities are fixed on the hanger body 9, are with apical axis 24 in the locating sleeve 25, and apical axis 24 is connected with handle 19, handle 19 is provided with plain cushion 21, and locating sleeve 25 is connected by register pin 26 with apical axis 24.

Embodiment 2, with reference to Fig. 1, Fig. 4, are on the basis of embodiment 1, are with nylon protective sleeve 23 on locating sleeve 25, and other are identical with embodiment 1.

When using the utility model, the axle of four-wheel position finder head can be installed in the copper sheathing 28, hanger body 9 lower ends two locating sleeves 25 are leaned against the wheel rim lower end, hold hanger and another hand-screw on the other hand and change hands handle 10, three locating sleeves 25 are enlarged rapidly synchronously, stretching leans against on the interior circle of wheel rim, two manual manipulation handles 1 then, make claw 2 catch on tire, the spring force of extension spring 8 becomes one hanger and wheel, this moment copper sheathing 28 endoporus not only with the wheel center concentric, and vertical with the wheel end face, guarantee the geometric accuracy after four-wheel position finder head axle is fit into copper sheathing 28; When using apical axis 24, rotatable handgrip 10 is put into maximum length simultaneously with three apical axis 24, operating grip 19, make apical axis 24 in place, upper end apical axis 24 is hung over the cylindrical of wheel rim, the hanger of being commissioned, proficiency rotary handle 10, three apical axis 24 are dwindled, tighten wheel rapidly, other steps are the same with use locating sleeve 25.
