The utility model has the advantages of smallness and lightness (2.7 kg), simple and convenient operation, time saving, labour saving and electricity saving. As long as a plug is inserted into a cigar lighter of a vehicle, an electric button is pressed to complete operation. Therefore, the utility model is an ideal vehicle-carrying tool for disassembling vehicle tyres.

Description

Small-sized automatically controlled hydraulic automobile tire dismantling spanner

The utility model belongs to traffic and transport field, and the spanner that particularly a kind of small-sized automatically controlled hydraulic automobile tire dismantling bolt of rear end plate is used is that desirable automobile is with the car special tool.

In recent years, home market released one after another electricity, pneumatic two class motor tires dismounting spanner, the former drives a series of reductors with alternating-current motor/AC motor to increase moment of torsion and reach the dismounting purpose, and its volume is big and heavy; The latter mostly is imported product, though than the former advanced person, but cost an arm and a leg, big and heave, also need specially join an Air compressor supply pressurized air could work, and the both can only be confined to the motor transport repair shop fixed point and use, and can not carry with car, therefore when the automobilist is in operation and tire fault occurs and need change spare tyre, still use at present nut setter spanner---this conventional tool that can carry with car, the gay still needs and wants boosting-rod, woman just to use to have wasted time and energy more during remove a tyre.

The purpose of this utility model is to provide a kind of small-sized automatically controlled hydraulic automobile tire dismantling spanner that can overcome above defective.

The technical solution of the utility model is that it comprises high pulling torque transmission at a slow speed and quick transmission two parts: the high pulling torque running part comprises that main motor reaches axle bonded assembly oil pump with it at a slow speed, hydraulic actuating cylinder is connected by oil pipe and oil pump, kinematic link one end that is provided with ratchet, directional lever is connected with the piston rod of hydraulic actuating cylinder, and the other end is connected with the main shaft that ratchet, driven gear and bolt collar are housed; Running part comprises power-transfer clutch, scroll bar and the turbine of paying motor and being coupling with it fast, turbine is by the driving gear on the driving gear shaft and the driven gear interlock mutually of high pulling torque running part at a slow speed, the terminals connecting band plug of two motors and the power lead of start button.

Little, in light weight, easy and simple to handle, the time saving and energy saving power saving of the utility model volume, deadweight 2.7Kg as long as plug is inserted in the automobile cigarette lighter, presses push button gently and can finish the work, and is the driver's tool of desirable dismounting motor tire.

Embodiment is described in detail in detail in conjunction with the accompanying drawings: the utility model comprises high pulling torque transmission at a slow speed and quick transmission two parts, the high pulling torque running part comprises that main motor 10 reaches axle bonded assembly oil pump 11 with it at a slow speed, hydraulic actuating cylinder 14 is connected with oil pump 11 by oil pipe 12,13, be provided with the kinematic link 15 of ratchet 17, directional lever 16, the one end is connected with the piston rod of hydraulic actuating cylinder 14, and the other end is connected with the main shaft 8 that ratchet 18, driven gear 7 and bolt collar 9 are housed; Running part comprises power-transfer clutch 2, scroll bar 3 and the turbine 4 of paying motor 1 and being coupling with it fast, turbine 4 is by driving gear 6 and driven gear 7 interlock mutually of high pulling torque running part at a slow speed on the driving gear shaft 5, the main terminals of paying motor 10,1, the power lead 20 of connecting band plug 21 and start button 19.

During use power-line plug 21 of the present utility model is inserted in the automobile cigarette lighter, then bolt collar 9 of the present utility model is enclosed within on the bolt that needs dismounting, directional lever 16 is pulled to the position of " dismounting " or " installation " again, at this moment press " dismounting " or " installation " on the start button 19, this moment, main motor 10 and oil pump 11 were worked simultaneously.Because load is bigger, the power-transfer clutch of paying on the motor 12 separates automatically, and main motor 10 and oil pump 11 are given hydraulic actuating cylinder 14 fuel feeding automatically repeatedly through oil pipe 12,13, make the piston rod crank motion in the hydraulic actuating cylinder 14, promote kinematic link 15, the ratchet 17 that makes it on it promotes ratchet 18 by bolt collar 9 rotations thereon of main shaft 8 drive dresses, and Bolt dismantling is loosening; At this moment, because the torsion on the bolt collar 9 reduces, the power-transfer clutch of paying on the motor 12 is no longer slided, realize first order deceleration transmission, again by turbine 4 through driving gear shaft 5, drive driving gear 6 and make deceleration transmission for the second time with driven gear 7, driven gear 7 drives bolt collar 9 fast rotational through main shaft 8, with the fast quick-detach of bolt.
