A device for dismantling and assembling suspension parts according to claim 1, characterized in that when mounting the rubber bushings of the connecting axles of the wheel gears, the torsion adapter is connected by thread to the adapter of connecting axles made with an external tapered thread for connection with an opening of the connecting axis, and on its external a guide bush is placed in diameter, and a stop is mounted on the bush, made in the form of a thick-walled washer with a centering collar under the tubular element and a recess under the rubber bushings connecting this wheel gears.

Description

DEVICE FOR DISASSEMBLY AND INSTALLATION OF PARTS FOR SUSPENSION

The useless model relates to garage equipment, in particular to devices for dismantling and mounting suspension parts.

A device for dismantling the torsion shaft of the suspension containing a screw, nut and tubular element 1.

The disadvantages of the known device is that with its help you can only dismantle the torsion shaft of the suspension.

The technical result achieved by the claimed constructive implementation is to reduce the complexity of the maintenance of the car by providing the ability to perform several operations for dismantling and mounting the suspension parts, and reduce friction when applying torque to the nut.

The specified result is achieved by the fact that between the nut and the tubular element there is a thrust bearing and a beam made with a flange part for supporting the tubular element, for example, a special key from a chauffeur tool and a hub part centered on the screw, and an adapter made with external threaded connections for the torsion hole or the lower king pin hole, or the connecting axis hole

wheel reducers when dismantling the corresponding element, and when mounting the rubber bushings of the connecting axles of the wheel reducers, the torsion adapter is threadedly connected to the adapter of the connecting axles made with an external tapered thread for connecting to the hole of the connecting axis, and a guide sleeve is placed on its outer diameter, and on the sleeve an emphasis is installed, made in the form of a thick-walled washer with a centering collar under the tubular element and a recess under the rubber bushings of the connecting axles of the wheel ed uktorov.

The inventive design is illustrated by drawings, where:

FIG. 1 - installation of the device when dismantling the torsion bar suspension;

FIG. 2 - installation of the device when dismantling the lower pivots of the front wheel gears;

FIG. 3 - installation of the device when removing the connecting axles of the wheel gears;

FIG. 4 - installation of the device when mounting the bushings of the connecting axles of the wheel gears.

The device comprises a screw 1, a nut 2, a tubular element 3, a thrust bearing 4, a beam 5 made with a flange part 6 for supporting the tubular element 3, and a hub part 7 centered on the screw 1, a torsion adapter 8 connected by a thread to the screw 1 and made with external threads for connection with the hole 9 of the torsion bar 10 or with the hole 11 of the lower pin 12, or with the hole 13 of the connecting axis 14 of the wheel gears, the adapter 15 of the connecting axles, made with an external conical thread for connecting with the hole 16 of the connecting axis 14, the guide sleeve 17, the stop 18, made in the form of a thick-walled washer with a centering; with a shoulder 19 under the tubular element 3 and a recess 20 under the rubber bushings 21 of the connecting axles 14 of the wheel gears.

When dismantling the torsion bar 10 of the suspension, the adapter 8 of the torsion bar connected to the screw 1 of the device is wrapped in the hole 9 of the torsion bar 10, while the tubular element 3 is located between the beam 5 and the nut of the mounting of the suspension arms. By turning the nut 2 through the thrust bearing 4, in order to reduce friction when applying torque to the nut 2, the torsion bar 10 is extruded from the slot of the pipe of the lower suspension arm.

When dismantling the lower pivots 12 of the front wheel gears, the torsion adapter 8 connected to the screw 1 of the device is wrapped in the hole 11 of the pivot 12, while the tubular element 3 is located between the beam 5 and the wheel gear housing. By rotating the nut 2, the pivot 12 is pressed out of the opening of the wheel gear housing.

When dismantling the connecting axes 14 of the wheel gears, the torsion adapter 8 connected to the screw 1 of the device is screwed into the hole 13 of the connecting axis 14, while the tubular element 3 is located between the beam 5 and the suspension arm. By rotating the nut 2, the connecting axis 14 is pressed out of the rubber bushings 21 of the suspension arm.

When mounting the bushings 21 of the connecting axes 14 of the wheel gearboxes, the adapter 15 of the connecting axes connected through the adapter 8 of the torsion bar with the screw 1 of the device is wrapped in a comic hole 16 of the connecting axis 14, while the tubular element 3 is located between the beam 5 and the stop 18 mounted on the adapter 15 connecting axes through the guide sleeve 17, and the emphasis 18 by the recess 20 is in contact with the rubber sleeve 21, pre-installed on the connecting axis 14 and in the hole of the suspension arm. By rotating the nut 2, the rubber bushings 21 are pressed into the hole of the suspension arm.

Pa JSC GAZ made samples of the proposed device that have passed the tests and received a positive assessment during the tests of GAZ 5923 cars.

This device will be used as part of a driver’s tool on GAZ-5923 production vehicles and their modifications, as well as as part of the MTO - BTR.
