The position-limited shaft technological scheme of electric vehicle of the present invention, electro-tricycle automatic transmission case is, position-limited shaft is installed on drive plate base plate, it is characterized in that position-limited shaft is spill I-shaped groove shape, the click-fit of recessed region 2 and drive plate, upper step 1 coordinates with flexible rod, when vehicle is made forward drive or slides, recessed region 2 pairs of ratchet activities of position-limited shaft are carried out spacing, when reverse-drive made by vehicle, position-limited shaft and flexible rod form circumference and intersect, and the step 1 of position-limited shaft forms auto-lock function with the I-shaped groove of flexible rod.
The position-limited shaft of electric vehicle of the present invention, electronic three wheel automatic transmission case, be installed on the drive plate base plate of automatic transmission, the ratchet close fit of position-limited shaft and flexible rod and drive plate, after automatic transmission case has installed the position-limited shaft described by this patent, revolutionize the roadability of electric motor car, unidirectional drive pattern can be adopted coasting ability is increased when forward drive made by vehicle, extend mileages of continuation, when backward running made by vehicle, position-limited shaft and flexible rod form circumference and intersect, and the step 1 of position-limited shaft forms auto-lock function with the I-shaped groove of flexible rod.
Described position-limited shaft is installed on drive plate base plate, it is characterized in that drive plate base plate fitting area 3 and the drive plate base plate close fit of position-limited shaft lower end, is connected firmly by riveting machine or electric welding.
Described position-limited shaft step 1, is characterized in that step 1 is placed in position-limited shaft top, step 1 straight to being highly less than or equal to 2mm, and radial diameter is less than or equal to 10mm.
Described recessed region 2, is characterized in that the radial diameter of recessed region 2 is less than or equal to 8mm, and recessed region 2 position is carried out spacing when vehicle makes forward drive or sliding state to the activity of drive plate ratchet.
Straight after described position-limited shaft and drive plate base plate connect firmly is less than or equal to 13.5mm to height H.
In a kind of form, when drive plate Bian is with two symmetrical ratchets, at least more than one position-limited shaft can connect firmly drive plate base plate in other spaces of drive plate, and the installation locating point of position-limited shaft should can crossover range at flexible rod.
Further, the centre of location of position-limited shaft is placed on camber line that the radius R at drive plate center is the positive and negative 2mm of 31mm is preferred feature.
