Abstract

The utility model discloses a two-gear speed changing device with intermediate power input for electric cars, which is characterized in that a first-gear brake is connected with an inner gear ring, an input wheel is connected with a sun gear by a drive gear, the sun gear is meshed with a planetary gear, the planetary gear is in driving connection with another sun gear, another gear ring is fixed in a shell, the other sun gear is meshed with the other planetary gear, the other planetary gear is connected with a differential mechanism, and a two-gear clutch is fixed on the inner gear ring. The two-gear speed changing device with intermediate power input for the electric cars can shift gears automatically when in running, has the advantages of small volume, low cost and simple structure, and can be arranged and maintained conveniently.

Description

The power input is at the electric vehicle second gear speed change gear of centre
Technical field
The utility model belongs to the speed changer field, especially relates to the second gear speed change gear of a kind of electric powered motor input in the centre.
Background technique
At present, automaitc shfit when the motor second gear speed change gear on the market can not be realized automobilism needs the Parking gear shift.Though market has one grade of speed change gear, do not satisfy the proportioning of car load operation moment of torsion, rotating speed and power output.
The model utility content
The purpose of this utility model provides a kind of electric vehicle second gear speed change gear of automaitc shfit can realize moving the time, to adapt to the needs of electric vehicle operation.
For solving the problems of the technologies described above, the utility model provides the electric vehicle second gear speed change gear of a kind of power input in the centre, it is characterized in that: one grade of break connects ring gear, wheel for inputting is by the driving gear sun gear that is in transmission connection, the engagement of sun gear and planet wheel, planet carrier another sun gear that is in transmission connection, another gear ring of housing internal fixation, another sun gear and the engagement of another planet wheel, another planet carrier connects differential mechanism; Fixing second gear clutch on the ring gear.
When the utility model can be realized moving the automaitc shfit volume little, be convenient to arrange, cost is low, simple in structure, easy to maintenance.
Description of drawings
Accompanying drawing is a structure principle chart of the present utility model.
