Abstract

The utility model relates to a universal running-in machine for wheel type automobiles, which is suitable for cold running-in of medium and smaller automobile engines. Parallel chains can hold up the driving wheels of the automobile and can transmit the power of a motor to the driving wheels, and therefore, the utility model can drive the engine to rotate for getting the purpose of cold running-in.

Description

The general running-in machine of wheeled motor vehicle

The utility model provides a kind of general running-in machine of using to the wheeled motor vehicle engine cold break-in after repairing.

After the operation of the motor of wheeled motor vehicle through certain hour or certain mileage, because parts depreciation or damage need the maintenance of disintegrating, often change many new parts during maintenance, as piston, cylinder sleeve, bearing etc., because the new parts of changing exist macroscopic view or microdefect inevitably, so, cooperatively interacting must just can reach kilter through break-in after a while between the component that rub, therefore, and concerning repairing high motor, the technical matters regulation must be carried out cold breaking in.In the time of the engine cold break-in, be repairing on the cold breaking in machine that high motor lifts special use.Since from the cold breaking in machine to treating that the power transmitting deice the motoring engine and the device that is fixedly connected can not be common to all engine models, so, a running-in machine can break-in type always limited, and this working method will be carried out the adjustment before the break-in, fixing of motor, power transmitting deice connects installation etc., so, efficient is low, and labor intensity is big.In addition, when motor was not pulled down the vehicle frame maintenance, cold running-in process can only be abandoned.

In order to address these problems, the power transmitting deice of the running-in machine that has adopts flexible axle, but the bind mode between flexible axle and the motor does not have much variations, and still need to dock, fix, so, the type of energy break-in is not fundamentally widened, and therefore workload and labor intensity do not reduce yet.

The purpose of this utility model is the running-in machine that will provide a kind of wheeled motor vehicle general, and it can simplify the cold breaking in program, alleviates labor strength, realizes that a real machine is general.

The purpose of this utility model is achieved in that the chain of using side by side holds up the driving wheel of wheeled motor vehicle, utilize the motor drive system principle of transferring power in the other direction, external impetus is passed to motor through side by side chain, driving wheel, transmission system, thereby, drive engine revolution, realize cold breaking in.

The utility model is owing to be to hold up wheel and with this transferring power by side by side chain, the speed changer conversion that required different rotating speeds leans on Motor Vehicle itself in the cold grinding process, so, its structure is simpler than used usually cold breaking in machine, and workloads such as adjustment, fixing, mounting or dismounting motor have been saved, alleviate working strength of workers, improved work efficiency.Simultaneously, realized that a real machine is general, because, realize cold breaking in no matter the motor of which kind of type as long as can make the driving wheel rotation of Motor Vehicle, just can drive engine revolution by transmission system.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Figure of description is the organigram according to the general running-in machine of wheeled motor vehicle that the utility model proposes.

Fig. 1 is plan view (sight line is parallel to the roller sprocket axial direction).

Fig. 2 is a plan view.

This running-in machine comprises two roller type sprocket wheels (1) and (3), and chain side by side (2) is enclosed within on roller type sprocket wheel (1) and (3), and roller type sprocket wheel (1) and (3) are installed on the base by bearing support (8) and (do not draw among the figure).The driving wheel of Motor Vehicle (9) is held up by chain (2) side by side.When motor (5) energising rotation, the power that produces passes to belt pulley (7) by belt pulley (6) through belt (4), belt pulley (7) is fixed on an end of roller type sprocket wheel (3), therefore, the power of motor has been passed to roller type sprocket wheel (3) through belt pulley (7) again, because the rotation of roller type sprocket wheel (3), drive chain (2) motion side by side, again because, there is enough big frictional force between chain and the wheel, so, driving wheel (9) quilt chain (2) driven rotary side by side, because the rotation of driving wheel (9), semiaxis (10), just and then rotation, so, power finally passes to motor (drawing among the figure) through transmission system and makes engine revolution, realizes cold breaking in.

Claims

The general running-in machine of wheeled motor vehicle, be specially adapted to the cold breaking in of medium-sized following motor car engine, it comprises a base, motor (5) is housed on base, roller sprocket (1,3), be installed on the base by bearing support (8), chain side by side (2) is looped around on two roller sprocket, it is characterized in that side by side chain (2) is held and transmission of power is given the driving wheel (9) of Motor Vehicle.
