Description
Technical field
The utility model relates to the automotive transmission field, and is more particularly a kind of with the automatic differential lock of the electric on automobile.
Background technique
the speed discrepancy of foreign steamer in when differential mechanism is mainly the balancing vehicle turning, thereby vehicle is turned smoothly and needn't expend too much energy, exactly because and the differential principle of differential mechanism and etc. torsional interaction, when Vehicle Driving Cycle is under abominable road conditions, wheel often can be absorbed in mud, sand ground or ice and snow road and make certain wheel-slip or even unsettled, thereby vehicle is got into a difficult position can't extricate oneself, the driver can expect being encased inside the hard objects such as stone usually below slip wheel in this case, to increase the adhesion of wheel, yet this method is often tried to be clever only to end up with a blunder, wheel is sunk deeper and deeper.
At present, some go-anywhere vehicles and high-grade SUV solution are pinned differential mechanism with differential lock exactly, make differential mechanism ineffective, make main reducing gear divide balanced to left and right semiaxis rotating speed, thereby more power distribution is gone to the wheel that does not skid, as seen the function of differential lock just is to guarantee when single wheel skids that the opposite side wheel can obtain enough large driving force, yet, the differential-speed lock mechanism of existing machinery formula is complicated, maintenance difficult, rate of fault is high, and is more loaded down with trivial details for common driver operation, is difficult to grasp flexibly and use.
Summary of the invention
In order to overcome above shortcomings part in prior art, the purpose of this utility model is to provide a kind of electric automatic differential lock, and it is simple in structure, and is reasonable in design, use simple operation, failure rate is low, long service life, good stability, practical, using effect is good, is convenient to promote the use of.
in order to reach above-mentioned purpose, the utility model adopts following concrete technological scheme: the automatic differential lock of electric, comprise the large shell of differential lock, be sleeved on the little shell of differential lock of large shell one end of differential lock and be arranged on the large shell of differential lock and the little shell of differential lock between and the planetary pinion fixed by cross axle, respectively be provided with a differential gear in the large shell of differential lock and the little shell of differential lock, each differential gear meshes with planetary pinion respectively, be provided with the generator permanent magnet of a plurality of both positive and negative polarity alternative arrangements in described differential gear, the differential gear overcoat has generator iron-core and generator coil, in described differential lock size shell, electromagnet coil and friction plate are housed, friction plate is arranged between generator iron-core and electromagnet coil, be respectively equipped with Regulation spring between electromagnet coil and differential lock size shell, screw, be respectively equipped with the speed limit centrifugal switch on the large shell of described differential lock and the little shell of differential lock.
Further, the described differential gear outside is provided with the first circular groove, one side of described generator iron-core and the first circular groove opposing side is established and is had the second circular groove, this second circular groove is connected with the first circular groove, described generator coil is arranged on the second circular groove of generator iron-core, and described generator permanent magnet is arranged on the first circular groove on the differential gear outside.
Further, the large shell of described differential lock and the little shell of differential lock are provided with for the accumulator tank of placing the speed limit centrifugal switch.
The utility model advantage compared with prior art is:
1, due to the generator that utilizes differential gear, generator permanent magnet, generator coil and generator iron-core to form, while when differential gear idle running, generating electricity, electromagnet coil power and the magnetic field that produces, check friction plate and make separately differential gear and housing self-locking, two semiaxis are connected firmly, obtain normally to travel thereby allow automobile be out of danger, this model utility has solved automobile single-wheel idle running and the problem of skidding;
2, increased the speed limit centrifugal switch, when differential gear reaches certain rotating speed, and the automatic tripping magnet coil electricity of speed limit centrifugal switch, prevent galloping and the magnetic field of electromagnet coil power and generation, check friction plate and make separately differential gear and housing self-locking, the problem that causes automobile normally not travel;
3, the utlity model has in sum simple in structurely, reasonable in design, use simple operation, failure rate is low, long service life, good stability, practical, using effect is good, is convenient to promote the use of.
