Purpose of the present invention is achieved through the following technical solutions:
A kind of motor vehicle brake fluid charges and discharge the design method of machine coupling, comprise and being used for fixing at half-coupling on the driving shaft and the half-coupling that is used for fixing on driven shaft, characteristics are: have parallel surface at the ora terminalis of described driving shaft half-coupling and be symmetrical in axis, form the cydariform boss, have parallel surface at the ora terminalis of driven shaft half-coupling and be symmetrical in axis, also form the cydariform boss; Between the cydariform boss of the cydariform boss of driving shaft half-coupling and driven shaft half-coupling, the cross geosynclinal block is installed, one end of described cross geosynclinal block has parallel surface and is symmetrical in axis, form the cydariform groove, the other end of cross geosynclinal block has parallel surface and is symmetrical in axis, also form the cydariform groove, the notch of two cydariform grooves is opposing radially to be 90 degree; The cydariform groove of the cydariform boss of described driving shaft half-coupling and cross geosynclinal block one end matches, and the cydariform groove of the cydariform boss of described driven shaft half-coupling and the cross geosynclinal block the other end matches.
Further, above-mentioned a kind of motor vehicle brake fluid charges and discharge the design method of machine coupling, and wherein, the half-coupling on the described driving shaft adopts pin to be connected with driving shaft.
Further, above-mentioned a kind of motor vehicle brake fluid charges and discharge the design method of machine coupling, and wherein, the half-coupling on the described driven shaft adopts key to be connected with driven shaft.
Substantive distinguishing features and obvious improvement that technical solution of the present invention is outstanding are mainly reflected in:
The present invention has adopted and has had cross recessed cross geosynclinal block, limits the cydariform boss that connects two half-couplings and is cross distribution at gyratory directions.In the rotation process, the cross geosynclinal block can be done each to slip, with satisfy coupling compensation diaxon install take place radially, the needs of conditions such as axial deviation or axis deviation intersection.When increasing compensation ability and realizing steady transmission, also simplified structure, improved the technology capability of part, be applicable to that the big or axis of alignment error has two between centers transmitting torques of bigger installation angle of declination, satisfies the transmission installation requirement that motor vehicle brake fluid charges and discharge machine.Whole apparatus structure is succinct, technological requirement is low, long service life, volume are little, and slidable adjustment guarantees alignment automatically, prevents that motor is stuck, and application should be widely promoted.

Embodiment
As shown in Figure 1, motor vehicle brake fluid charges and discharge the hitch bar of machine, comprise driving shaft half-coupling 3 and driven shaft half-coupling 1, driving shaft half-coupling 3 adopts pin to be connected with the rotating shaft of motor 5, thereby be fixed in the rotating shaft of motor 5, the rotating shaft of driven shaft half-coupling 1 and pump 4 adopts key to be connected, thereby is fixed in the rotating shaft of pump 4, between the cydariform boss of the cydariform boss of driving shaft half-coupling 3 and driven shaft half-coupling 1 cross geosynclinal block 2 is installed.
As Fig. 2 a, 2b, 2c, have parallel surface at the ora terminalis of driven shaft half-coupling 1 and be symmetrical in axis, form the cydariform boss.
As Fig. 3 a, 3b, an end of cross geosynclinal block 2 has parallel surface and is symmetrical in axis, forms the cydariform groove, and the other end of cross geosynclinal block 2 has parallel surface and is symmetrical in axis, also forms the cydariform groove, and the notch of two cydariform grooves is opposing and radially be 90 degree.
As Fig. 4 a, 4b, have parallel surface at the ora terminalis of driving shaft half-coupling 3 and be symmetrical in axis, form the cydariform boss.
Install when using, the cydariform groove of the cydariform boss of driving shaft half-coupling 3 and cross geosynclinal block 2 one ends matches, and the cydariform groove of the cydariform boss of driven shaft half-coupling 1 and cross geosynclinal block 2 the other ends matches.The cydariform boss that is driving shaft half-coupling 3 inserts the cross recess that places cross geosynclinal block 2 therebetween with relative intersection of cydariform boss of driven shaft half-coupling 1, the flute profile of the end face of half-coupling and boss thereof and cross geosynclinal block adapts and can leave an amount of gap on demand, to realize the slip of cross geosynclinal block in the coupling operation process, compensate that two between centers exist radially, axial deviation or two between centers exist a certain amount of installation angle excursion the time do not interfere.Even when there was deviation in the coaxality of motor and pump installation, cross geosynclinal block 2 slided between driven shaft half-coupling 1 and driving shaft half-coupling 3 automatically, motor 5 can easily drive pump 4 and rotate, and is not stuck, thereby effectively regulates alignment.
In sum, the invention provides a kind of compact structure, easily processing, exist simultaneously radially at two between centers, axially or axis smooth rotation under the condition of deflection crossing angle of installation needs is arranged, the hitch bar of transmitting torque, owing to adopted to have cross recessed cross geosynclinal block, limited the cydariform boss that connects two half-couplings and be cross distribution at gyratory directions.In the rotation process, the cross geosynclinal block can be done each to slip, with satisfy coupling compensation diaxon install take place radially, the needs of conditions such as axial deviation or axis deviation intersection.When increasing compensation ability and realizing steady transmission, also simplified structure, improved the technology capability of part, be applicable to that the big or axis of alignment error has two between centers transmitting torques of bigger installation angle of declination, satisfies the transmission installation requirement that motor vehicle brake fluid charges and discharge machine.
