The invention discloses a safety lock of a double-shift motor actuator of an automatic transmission, and belongs to the field of vehicle transmission components. An interlocking shell and two self-locking shells are bolted on a mechanism mounting shell, and each provided with a right vertical toggle finger slideway and a left vertical toggle finger slideway; right and left vertical toggle fingersdo reciprocating motion in the right vertical toggle finger slideway and the left vertical toggle finger slideway from top to bottom; the interlocking shell is internally and horizontally provided with an upper interlocking slideway and a lower interlocking slideway, and the interlocking slideways transversely penetrate through the interlocking shell; each self-locking shell is internally and horizontally provided with an upper interlocking slideway and a lower interlocking slideway, and the end, facing the interlocking shell, of each interlocking slideway is open; the upper interlocking slideway and the lower interlocking slideway are each provided with upper and lower interlocking sliding pins internally, and the upper interlocking slide way and the lower interlocking slide way are eachprovided with upper and lower self-locking sliding pins internally. The safety lock is used for ensuring that only one group of combination devices of different shift gears of the double-shift motor actuator is pushed to the combination position, and accidents of the gears engaged or in neutral positions due to accidental causes are avoided.
Description
technical field [0001] The invention relates to the technical field of vehicle transmission components, in particular to a safety lock for an automatic transmission double shift motor actuator. Background technique [0002] During the shifting operation of the vehicle transmission, only one specific gear is allowed to be combined at a time. If two gears with different speed ratios are combined at the same time, the transmission will be damaged. When the gearbox is working in conjunction with a specific gear, if the gear is out of the working position due to accidental reasons, the gearbox will not be able to continuously output torque. The shift actuator of the existing mechanical automatic transmission adopts a gear selection motor to cooperate with a gear shift motor to perform the gear selection and shift operation. The shifting safety structure is composed of an interlocking plate. There is a movement groove on the interlocking plate, and the shift finger moves in the m...
