Description

Electronlmobil circuit type transmission system
Technical field
The utility model relates to the constituent elements of electronlmobil, is specially a kind of electronlmobil circuit type transmission system.
Background technology
At present in the transmission design and use of electronlmobil, still continue to use mechanical transmission, use electrical motor not mate as the pattern pole of power with electronlmobil, thus cause, volume weight large in electronlmobil in-fighting in change-speed box link, take up room large, high cost series of problems.Have impact on the driveability of electronlmobil greatly.
Summary of the invention
The utility model adopts mechanical structure to there is large, the high problem affecting running car ability of cost that takes up room to solve existing electric automobile gear change mechanism, provides a kind of electronlmobil circuit type transmission system.
The utility model adopts following technical scheme to realize: electronlmobil circuit type transmission system, comprises total disconnector, electrical motor, positive contactor, reversion contactless switch, stop button, the compound button that moves ahead, retreats compound button; Three phase line between total disconnector and electrical motor is arranged in parallel the three-phase contact of positive contactor and the three-phase contact of the contactless switch that reverses, the three-phase contact of positive contactor adopts positive phase sequence wiring, and the three-phase contact of reversion contactless switch adopts negative-phase sequence wiring; By retreating the normally open contact of compound button, the head end of the first series arm that the normally closed interlock of the compound button that moves ahead, the unidirectional closed contact of reversion contactless switch, the coil of positive contactor are connected in series successively is by the first-phase connection of stop button and total disconnector, the end of the first series arm and the second-phase connection of total disconnector, and the self-locking contact normally open contact of retrogressing compound button being parallel with positive contactor; The head end of the second series arm be connected in series successively by the unidirectional normally closed interlock of the normally open contact of the compound button that moves ahead, the normally closed interlock retreating compound button, positive contactor, the coil of reversion contactless switch is by the first-phase connection of stop button and total disconnector, the end of the second series arm and the second-phase connection of total disconnector, and the self-locking contact normally open contact of the compound button that moves ahead being parallel with reversion contactless switch.
During operation, when electronlmobil retreats, press retrogressing compound button, the normally open contact retreating compound button closes, and the coil of positive contactor obtains electric adhesive, the three-phase contact closure of positive contactor, electrical motor rotates forward, meanwhile, the self-locking contact closure self-locking of positive contactor, unclamps retrogressing compound button, keep connecting and rotate forward control circuit, and the unidirectional normally closed interlock cut off of positive contactor, the three-phase contact of reversion contactless switch can not obtain electric interlocking, driving electric back of automobile, when electronlmobil needs to move ahead, press the compound button that moves ahead, the normally closed interlock of the compound button that moves ahead disconnects, the coil losing electricity release of positive contactor, and the three-phase contact of positive contactor disconnects, and electrical motor rotates forward stopping, the self-locking contact of positive contactor first resets disconnection, disconnect and rotate forward control circuit, reset after the unidirectional normally closed interlock of positive contactor closed, move ahead compound button normally open contact after closed, the coil of reversion contactless switch obtains electric adhesive, the three-phase contact closure of reversion contactless switch, electrical motor reverses, meanwhile to reverse the self-locking contact closure of contactless switch, connect reverse turn control circuit self-locking, the unidirectional closed contact of reversion contactless switch first disconnects, make the coil of positive contactor can not obtain electric interlocking, unclamp retrogressing compound button, move ahead compound button normally closed interlock after reset closed, the normally open contact of compound button of moving ahead first resets disconnection, continue to make the coil of reversion contactless switch obtain electric adhesive by the self-locking contact of closed reversion contactless switch, electronlmobil is in forward traveling, when electronlmobil needs to stop, pressing stop button, the coil losing electricity release of reversion contactless switch, electrical motor reversion stops operating, and the compound button that moves ahead, retrogressing compound button realize interlocking, and electrical motor stall, electronlmobil is in dead ship condition.Overcoming existing electric automobile gear change mechanism adopts mechanical structure to there is large, the high problem affecting running car ability of cost that takes up room.
The utility model reasonable in design is reliable, the transmission function of the principle of electrical motor reversible transformation switch for electronlmobil, make electrical motor after accepting switch order, rotate and reverse, while reducing electric power in-fighting, save usage space, and then ensure the driveability of electronlmobil.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
