Description
Technical field
The utility model relates to Clutch Technology field, specifically a kind of purely mechanic clutch boosting-type used for electric vehicle two grades
Fluid drive assembly.
Background technology
Two grades of speed changing assemblies of middle-size and small-size in the market electric automobile configuration have two kinds of citation forms: the 1st, one is manual
Mechanical type speed changing assembly；2nd, a kind of is electronic controlling mechanical type automatic speed changing assembly.The first Manual mechanical speed changing assembly, uses
Manual shift fork is shifted.The different operation techniques of human pilot and the judgement difference to vehicle running state, drastically influence
Gear shift operation smooth and easy, can cause gear to beat tooth when serious.The second electronic controlling mechanical type automatic speed changing assembly, manual shift fork
Change electric shifting fork into, and the action of electric shifting fork, the velocity sensor of electronic control unit is fed back to electronics rate signal
Control unit, then electronic control unit sends instruction, electric shifting fork action, thus realizes speed change.During due to electronics unit
The factors such as the reliability of part is not enough, operating vibrations, frequently result in speed change malfunctioning, again due to the switching of gear position, and automobile
Driver and crew can feel stronger pause and transition in rhythm or melody sense, i.e. dubs the sensation of brake., generally there is gearshift and have some setbacks in both the above speed changing assembly
Freely, shift is malfunctioning, the obvious situation of speed change pause and transition in rhythm or melody sense, makes middle-size and small-size electric automobile ride comfort be substantially reduced.
Utility model content
The purpose of this utility model is to provide a kind of purely mechanic clutch boosting-type gearless to switch, with speeds control gearshift
The automatic gear shifting speed changing assembly on opportunity, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of the utility model offer:
A kind of purely mechanic clutch boosting-type two-shift automatic variable speed assembly used for electric vehicle, including motor connects dish, described motor

Compared with prior art, the beneficial effects of the utility model are: the utility model simple in construction, reasonable in design, case
Internal gear is in engagement all the time, in running, does not has gear clutch process will not occur to beat tooth phenomenon.During low speed,
High gear is equivalent to flying wheel, rotates together with low-speed gear, and during gearshift, simply gear is from slowly running at a high speed
The process rotating, owing to certain energy laid in by gear itself, makes smooth gear shifting stable.During low speed, moment of torsion is big, climbing
Ability is strong, it is adaptable to mountain area travels with slope road.During high speed, motor can be made to operate in invariable power region, both improve course continuation mileage,
Add again speed.
The conversion of the utility model height low speed is steady, smooth and easy, is suitable for urban district state of cyclic operation and travels, very energy-conservation.When gearshift,
Owing to two axle rotating speeds are moderate, during gearshift, clutch block is from being slid onto combination, has a buffering area, and gearshift does not has pause and transition in rhythm or melody sense.Owing to increasing
Cam reinforcement locking device, clutch block is of short duration with wheel hub to be separated because the minor variations of speed causes to make vehicle be unlikely to, it is to avoid
Vehicle throws switch in high-speed cruising.
