Abstract
The invention proposes an automatic operation mechanism of a two-gear mechanical transmission for an electric vehicle. The mechanism comprises a gear shifting actuation mechanism consisting of a shell, a gear shifting shaft and a gear shifting poking head; a motor with a turbine worm speed reducing mechanism is arranged at one end of the gear shifting shaft; a turbine of the turbine worm speed reducing mechanism is in transmission connection with one end of the gear shifting shaft; a turning position sensor is arranged at the other end of the gear shifting shaft, and is fixedly connected with the gear shifting shaft; and the turning position sensor monitors a gear shifting position and sends a signal to a control unit so as to judge the gear shifting position. The mechanism is simple in structure and reliable and effective in work; compared with adoption of switching value signals or integration of sensor detecting gear signals on the motor in the prior art, the mechanism directly measures the gear shifting shaft to achieve more accuracy, eliminates such interference factors as a transmission gap between the motor and the gear shifting shaft, and can finish adjustment and control of a gear shifting torque in the gear shifting process more effectively.
Description
Technical field
The present invention relates to electrical automobile two gear mechanical transmission automatic controllers, especially a kind of two gears mechanical transmission automatic controller used for electric vehicle.
Background technology
Automobile is the indispensable vehicles of the mankind, but with the increasingly serious weight of environmental pollution, the continuous reduction of non-renewable resources, develops energy-conservation and new-energy automobile has become the inevitable choice of countries in the world.Currently, China it is important that propulsion pure electric automobile and plug-in hybrid-power automobile industrialization, to lift China's automobile industry overall technology level.
Electric automobile uses two speed transmission speed change scheme, has been obtained for being widely recognized as in the industry.How to realize automatically controlling using mechanical transmission, also possess many successful stories.Table one is the retrieval result of phase patent：
Table one：
In above retrieval result, patent 1 is a kind of sensing system for detecting automatic transmission gear gear, and it is located in gearbox near an arresting disc, and the system includes an encoder and at least one the position sensor relative with encoder.Encoder is one has at least one to finish code track tape thereon, wherein sensor and the code track juxtaposition finished, so as to produce the data signal of a position for representing encoder apparatus and its corresponding gear.Patent 2,3,4,5,6 discloses the automatic speed changer for machine of new structure, larger change has been done on the basis of non-clashing gear set, to reach the function of fluid drive, therefore it is more expensive to manufacture, is unfavorable for the repacking of standard machinery speed changer on in-use automotive.
Patent 7,8 and 14 uses fluid torque-converter to coordinate fixed speed reducing ratio or planetary gears to provide larger range of speed change to make up the deficiency of single fast ratio, but fluid torque-converter inefficient and labyrinth in itself hinders its extensive use.
Patent 9 uses the switching of hydraulic means control realization height gear, hydraulic system complexity in itself and the requirement to sealing, and 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, it is proposed that a kind of new departure.
Patent 10 realizes that two gears switch using simple planetary arrangement, and patent 12 provides one kind using multiple clutches, and the scheme that gear shift is realized in adhesive is separated by it.Such scheme is required to complete gear shifting action by hydraulic control system.Patent 13 discloses a kind of two grades of automatic speed changer for machine with dry clutch, and clutch is different with traditional arrangement form.Operation clutch and combined cover can realize that power does not interrupt gear shift.There are active friction plate, driven friction disk and clutch compressing disc in the clutch assembly that automatic transmission disclosed in patent 15 is used, combination by magnet control active friction plate and driven friction disk with separate, shift fork is driven by stepper motor and then drives the synchronizer clutch collar to carry out the automatic switchover of gear.Such scheme causes the increase of system architecture complexity, and control difficulty is increased.
Patent 16 realizes shifting using motor control machinery speed changer, relative to pneumatically or hydraulically scheme, without arrangement power source in addition, is conducive to being used on electric automobile.But the drive range detection mode for being proposed, there is a problem of inaccurate, be unfavorable for the accurate control of shift process.
The content of the invention
For used for electric vehicle two gear mechanical transmissions, the present invention proposes a kind of two gears mechanical transmission automatic controller used for electric vehicle, and low cost changes minimum to two gear mechanical transmissions, gearshift overall process each position can accurately be detected, be advantageously implemented more intelligent shift process control.
Technology design：For used for electric vehicle two gear mechanical transmissions only need in itself height two gears, can realize that automobile swings to traveling using motor reversal, speed changer need not reverse gear, therefore its only need to setting shift control apparatus and without block selecting device.
Technical scheme：A kind of two gears mechanical transmission automatic controller used for electric vehicle, including the gear shifting actuating mechanism that housing, shifting shaft, gear shifting pulling head are constituted, it is characterised in that：Arrange a motor for carrying turbine worm reducer structure in shifting shaft one end, the turbine of turbine worm reducer structure with shifting shaft one end in drive connection；The shifting shaft other end is provided with angle position sensor, and angle position sensor is fixedly connected with shifting shaft；Signal is simultaneously transmitted to control unit by angle position Sensor monitoring drive range, to judge drive range.
Beneficial effect：The present invention drives shifting shaft to rotate by carrying the motor of turbine worm reducer structure, and signal is simultaneously transmitted to control unit by angle position Sensor monitoring drive range, to judge drive range.Simple structure of the present invention, reliable operation and effectively, compared to original use on-off model or on motor, integrated sensor detects shift signal, program direct measurement shifting shaft, it is more accurate, the disturbing factor such as drive gap between motor and shifting shaft is eliminated, regulation and control to torque of shifting gears in shift process can be more effectively completed.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
With reference to shown in Fig. 1, the present invention is further described as follows：A kind of two gears mechanical transmission automatic controller used for electric vehicle, including the gear shifting actuating mechanism that housing 5, shifting shaft 4, gear shifting pulling head 7 are constituted, the parts and assembling structure of the gear shifting actuating mechanism are all prior arts（What shifting shaft 4 can be rotated is supported in housing 5, mounting hole and the spline fitted of shifting shaft 4 of the upper end of gear shifting pulling head 7）, it is not described here in detail；Arrange a motor 1 for carrying turbine worm reducer structure 2 in shifting shaft one end, the turbine 2-1 of turbine worm reducer structure with the one end of shifting shaft 4 in drive connection 3；The shifting shaft 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 transmitted into control unit, to judge drive range.
The above-mentioned motor 1 and angle position sensor 6 that carry turbine worm reducer structure 2 is prior art matured product, and the indexs such as power of motor, angle position sensor detection range should be taken into full account during apolegamy.
