Abstract

The utility model discloses an auto-jack of the automobile for automobile maintenance and repair. The auto-jack of the automobile can conveniently lift an automobile by the kinetic energy of the automobile itself. The auto-jack of the automobile which is composed of a peak-shaped location base and at least two lifting drums can be make to a fixed type or a portable type. The utility model which is suitable for lifting various automobiles has the advantages of simple structure and low cost; also, the life of the automobile is fast, and the damage not easily occurs.

Description

Auto-jack of automobiles

The apparatus that automatically automobile jack-up is come that uses when the utility model is a kind of servicing a car.

Automobile maintains, when repairing or changing of tire, parts, all need automobile one sidecar wheel Zhi Dingqi is come, and makes wheel unsettled, so that work.Three, the forties, the kiln car pusher tool adopts the tooth jack more, is replaced by hydraulic jack subsequently, since the sixties, the vehicle maintenance and repair place is many again with electronic, pneumatic jack.These top car devices respectively have merits and faults: the tooth jack is sturdy and durable, but uses difficultly, and efficient is low; Hydraulic jack Zhi Dingli is big, but the epithelium rapid wear uses effort; Pneumatic, electronic jack is only limited to power supply is arranged, the special-purpose place of source of the gas, but fault is more.

The purpose of this utility model just is: design a kind of above-mentioned jack defective that can overcome, and the easy apparatus that can utilize automobile kinetic energy own that automobile jack-up is come.

The utility model is achieved like this: this automatic top car device is made of with two that are connected with positioning seat by the bindiny mechanism cylinders that rise and fall the peak shape positioning seat at least.During this automatic top car device work, be to use object of which movement counteraction displacement principle, utilize car engine start after, the kinetic energy of the wheel tractor wheel automobile that rises and falls.When the jack-up automobile, only need the place ahead or the rear of cylinder of rising and falling near wheel with the diameter minimum of automatic top car device, when wheel, wheel drives cylinder and rolls going up on ground in the opposite direction with wheel side, thereby clamp-ons under the wheel, original place jack-up car, use other bearing set supporting shafts or other positions of automobile immediately, launching trolley crop rotation and last time rightabout rotation are just lifted out automatic top car device then, make wheel unsettled, finish the task of jack-up car.When falling car, the cylinder that rises and falls that again will this automatic top car device diameter minimum, is clamp-oned under the wheel when wheel near under the wheel, and the extruding wheel rises, and takes out bearing set, and wheel remakes counter-rotating, just lifts out top car device, and wheel lands.Therefore, as long as automotive wheel has a tire to have gas just can use this automatic top car device automobile that rises and falls.

Positioning seat shape of the present utility model is with peak shape, and its front and the contacted surface of automotive wheel outer rim are a curved surface, and its curvature should or adaptation consistent with the curvature of automotive wheel outer rim.What special requirement the back of this positioning seat does not have, make common inclined-plane, curved surface all can, also can make some automotive driven front-wheel of the confession flexion of usefulness plate that rises and falls that rises and falls as required, this plate that rises and falls is risen and fallen by lift.That is to say: the vehicle front that has is a flower wheel, can not drive this automatic top car device clamp-ons under the tire, during as need jack-up front-wheel, the activity that then vehicle front can be driven towards car device back, automatic top is risen and fallen on the plate, after front wheel spindle is supported device and supports, puts down the activity plate that rises and falls by lift, wheelie, when falling car, only motor vehicle slightly just can be taken out bearing set.But in the reality maintenance, the chance of a top front-wheel is few.

The diameter of the cylinder that rises and falls of the present utility model is unequal, and each drum sleeve is on drum shaft, and drum shaft is bearing on the bearing seat at two ends.The cylinder that rises and falls connects by bindiny mechanism each other, and links to each other with positioning seat, after assembling, cylinder can be rolled on the ground back and forth, moves around on the ground and gets final product thereby drive whole automatic top car device.In these cylinders that rise and fall, with the diameter maximum near the cylinder of peak shape positioning seat, during the work of top car device, at first contact the diameter minimum of the cylinder of wheel automatically, all roller arrangement of rising and falling become stepped appearance, each other at a distance of a distance, so that rise and fall automobile.

Positioning seat of the present utility model and the contacted curved surface of automotive wheel outer rim, the rise and fall surface of the upper surface of plate and the cylinder that rises and falls of activity is general surface or annular knurl, also can wrap one deck flexible material layer, the friction when automobile is risen and fallen in noise when working to reduce top car device and increase at the cylinder surface that rises and falls.

The utility model can be made the fixing fixed type of structure as required, but also can be made into the portable of Zhe, for the usefulness of driving maintenance.

Because the utility model is to rely on the kinetic energy of automobile own, utilize simple roller and the positioning seat automobile that can rise and fall automatically, so simple in structure, cost is low, and not fragile.The time of at every turn rising and falling only needs several seconds, and the automobile that rises and falls is convenient to be suitable for.

Further be illustrated below in conjunction with embodiment and accompanying drawing:

Fig. 1 is a kind of topology view of the present utility model.

Fig. 2 is the birds-eye view of Fig. 1.

Fig. 3 is another kind of topology view of the present utility model (band activity rise and fall plate).

As depicted in figs. 1 and 2, the peak shape positioning seat (1) of the automatic top of this automobile car device is welded on the steel skeleton with steel plate and forms, contacted curved surface curvature of positioning seat (1) front and automotive wheel and automotive wheel outer rim curvature adapt, be arc, its curved surface makes general curved surface or carries out annular knurl processing.Positioning seat (1) back is the curved steel plate, and both sides are steel plate.The top car device garden pillar buoy that cylinder (2), (4), (5), (6) are made for steel material or other metallic materials that rises and falls, the big I of its each diameter of cylinder is determined as required.The diameter minimum of cylinder (4), cylinder (2), (6) are isometrical and maximum.Each cylinder appearance is surrounded by one deck flexible material such as hard rubber layer (10), and cements with adhesive, and drum sleeve is on drum shaft (8).These cylinders are by bindiny mechanism such as contiguous block (3), and bearing (9) and nut (7) interconnect, and are connected with positioning seat (1), are arranged in stepped appearance, and the distance of being separated by mutually.When this automatic top car device is worked, the automotive wheels of rotating at first contacts cylinder (4), cylinder (5), (6) are involved under the wheel successively then, when felly contacts with the curved surface of positioning seat (1), just be blocked parking, thereby jack-up car easily automatically is then with other bearing sets supporting automobiles.The counter-rotating automotive wheel lifts out top car device, just can keep in repair.

Fig. 3 has the rise and fall another kind of topology view of the automatic top of automobile car device of plate of activity.The curved wedge activity that is welded with the steel plate plate (11) that rises and falls is contained in the back of the automatic top of automobile car device peak shape positioning seat (1), and cam mechanism rises and falls by rising and falling.When the lock pin (13) of cam handle (12) is pulled out, the activity plate (11) that rises and falls is fallen, thereby make vehicle front unsettled.
