The utility model discloses simple structure, reliable operation and effective, compare original adoptions switching value signal or on the motor integrated sensor detect and keep off a signal, this scheme direct measurement selector shaft, more accurate, got rid of between motor and the selector shaft interference factor such as transmission clearance, can more effectively accomplish regulation and the control of in -process to the moment of shifting gears of shifting gears.
Description
Technical field
The utility model relates to electrical automobile two gear mechanical transmission automatic controllers, especially a kind of two gear mechanical transmission automatic controllers used for electric vehicle.
Background technique
Automobile is the traffic tool that the mankind are indispensable, but day by day seriously weighing along with environmental pollution, the continuous minimizing of non-renewable resources, develops the inevitable choice that energy-conservation and new-energy automobile has become countries in the world.Current, the emphasis of China advances pure electric automobile and plug-in hybrid-power automobile industrialization, to promote China's automobile industry overall technology level.
Electric vehicle adopts two speed transmission speed change scheme, has obtained extensive accreditation in the industry.How to utilize mechanical transmission to realize automatically controlling, also possess a lot of successful story.Table one is the result for retrieval of phase patent:
Table one:
In above result for retrieval, patent 1 is a kind of sensing system detecting automatic transmission gear gear, and it is positioned near gearbox arresting disc, and this system comprises the encoder sensor relative with encoder with at least one position.Encoder is one to be had at least one and finishes code track tape thereon, wherein sensor and the code track juxtaposition finished, thus produces one and represent the position of encoder apparatus and the digital signal of corresponding gear thereof.Patent 2,3,4,5,6 discloses the automatic speed changer for machine of new structure, all on the basis of non-clashing gear set, do larger change, to reach self-shifting function, therefore manufacture cost is high, is unfavorable for the repacking of conventional machinery speed changer on in-use automotive.
Patent 7,8 and 14 adopts fluid torque converter to coordinate fixing reduction speed ratio or planetary gears to provide wider speed change to make up the deficiency of single speed ratio, but the poor efficiency of fluid torque converter itself and labyrinth hinder its extensive use.
The switching of what patent 9 adopted is hydraulic pressure installation control realization height gear, the complexity of hydraulic system itself and the requirement to sealing, gear shifting force size adjustment difficulty etc. makes its advantage be not so good as electric gear shifting mechanism.
Patent 11 realizes parking braking for automotive dynamoelectric machine formula speed changer, proposes a kind of new departure.
Patent 10 adopts simple planetary arrangement to realize two gears switchings, and patent 12 provides the multiple clutch of a kind of employing, is separated by it scheme that adhesive realizes gear shift.Such scheme all needs to complete gear shifting action by hydraulic control system.Patent 13 discloses a kind of second gear automatic speed changer for machine with dry clutch, and clutch is different with traditional arrangement form.Operated clutch and combined cover can realize power and not interrupt gear shift.Active friction plate, driven friction disk and clutch compressing disc is had in the clutch assembly that automatic transmission disclosed in patent 15 adopts, by the combination of magnet control active friction plate and driven friction disk be separated, drive shift fork by stepper motor and then drive synchronizer clutch collar to carry out the automatic switchover of gear.Such scheme all causes system architecture complexity to be increased, and controls difficulty and strengthens.
Patent 16 adopts Electric Machine Control machinery speed changer to realize shifting, relative to pneumatic or hydraulic solution, without the need to arranging power source in addition, is conducive to adopting on electric vehicle.But the drive range detection mode proposed, exists coarse problem, be unfavorable for the accurate control of shift process.
Summary of the invention
For two gear mechanical transmissions used for electric vehicle, the utility model proposes a kind of two gear mechanical transmission automatic controllers used for electric vehicle, cost is low, change minimum to two gear mechanical transmissions, accurately can detect gearshift overall process each position, be conducive to realizing more intelligent shift process and control.
Technical conceive: only need height two gears for two gear mechanical transmissions itself used for electric vehicle, utilize motor reversal can realize vehicle backing to traveling, speed changer is without the need to reversing gear, therefore its needs arrange shift control apparatus and without the need to block selecting device.
The technical solution of the utility model: a kind of two gear mechanical transmission automatic controllers used for electric vehicle, comprise the gear shifting actuating mechanism of housing, shifting shaft, gear shifting pulling head formation, it is characterized in that: arrange a motor carrying turbine worm reducer structure in shifting shaft one end, the turbine of turbine worm reducer structure with shifting shaft one end in being in transmission connection; The shifting shaft the other end is provided with angle position sensor, and angle position sensor is fixedly connected with shifting shaft; Signal is also passed to control unit by angle position Sensor monitoring drive range, to judge drive range.
Beneficial effect: the utility model drives shifting shaft to rotate by the motor carrying turbine worm reducer structure, and signal is also passed to control unit by angle position Sensor monitoring drive range, to judge drive range.The utility model structure is simple, reliable operation and effectively, compare original employing on-off model or integrated transducer detection shift signal on motor, the program directly measures shifting shaft, more accurate, to eliminate between motor and shifting shaft the disturbing factors such as drive gap, more effectively can complete the regulating and control to gearshift moment in shift process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Shown in composition graphs 1, further describe the utility model as follows: a kind of two gear mechanical transmission automatic controllers used for electric vehicle, comprise the gear shifting actuating mechanism of housing 5, shifting shaft 4, gear shifting pulling head 7 formation, the component of described gear shifting actuating mechanism and assembly structure be all prior art (shifting shaft 4 can rotate be supported in housing 5, the mounting hole of gear shifting pulling head 7 upper end and shifting shaft 4 spline fitted), be not described in detail at this; Arrange a motor 1 carrying turbine worm reducer structure 2 in shifting shaft one end, the turbine 2-1 of turbine worm reducer structure with shifting shaft 4 one end in being in transmission connection 3; The shifting shaft the other end is provided with angle position sensor 6, and angle position sensor 6 is fixedly connected with shifting shaft 4; Angle position sensor 6 is monitored drive range and signal is passed to control unit, to judge drive range.
