Abstract
The utility model provides a gear-shifting execution mechanism, which is used for an electrically-controlled mechanical type two-gear automatic transmission of an electric automobile, wherein an intermittent movement grooved wheel mechanism is additionally arranged so as to satisfy location requirement of a transmission in neutral gear. Furthermore, the grooved wheel mechanism has the advantages of simple structure, small size and high mechanical efficiency. The grooved wheel mechanism can transpose stably and intermittently.
Description
Technical field
The utility model relates to a kind of gear-shifting actuating mechanism of speed changer, relates to a kind of gear-shifting actuating mechanism that is used for electric vehicle electric-controlled mechanical two gear automatic speed variators especially.
Background technique
At present, electric vehicle needs bigger driving moment when starting and climbing, and when cruising, need the higher speed of a motor vehicle, in order to reduce requirement to the drive motor service behaviour, the speed changer that generally needs one two grades of couplings, high-revolving performance requirement when high torque (HT) and cruising in the time of could satisfying electric vehicle simultaneously and start climbing.
In order to overcome this problem, make pure electric automobile lighten the burden cutting down cost by loss of weight.Better come into the market, serve masses.Because electric vehicle is typically equipped with entire car controller (HCU), makes the operating mechanism of mechanical two speed gear can realize electronic control, just electric control mechanical type automatic speed variator (AMT).Because ordinary clutch generally only suits moving than under the slow-speed of revolution, the work requirements that can't adapt to electric vehicle, the more important thing is that motor has rotational speed regulation ability and littler rotary inertia better than motor, carry out the speed governing gearshift so electric vehicle can be cancelled clutch fully.
Yet in case cancel clutch, just need regulate motor speed, itself and actual vehicle speed are complementary so that engage a gear at the neutral position of speed changer.But common electric machine does not have the such position control accuracy of actuating motor, so can't guarantee to be parked in neutral position exactly after speed changer moves back shelves, just can't guarantee further to regulate motor speed and reliable engage a gear afterwards yet.Therefore need a kind of gear-shifting actuating mechanism of design to solve the problems referred to above.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of gearshift actuator, has increased the Geneva mechanism of intermittent movement in this mechanism, satisfies the demand of transmission neutral location positioning.And Geneva mechanism is simple in structure, and boundary dimension is little, the mechanical efficiency height, and can carry out transposition more reposefully, off and on.
This gear-shifting actuating mechanism mainly is made up of gear shifting motor, Geneva mechanism and shift lever.Wherein gear shifting motor adopts brush direct current motor.Geneva mechanism is made up of sheave and dial.The annexation of these mechanisms is as follows: gear shifting motor directly links to each other with the dial of Geneva mechanism by output shaft, and the dial in the Geneva mechanism matches with evagination locking arc by indent locking arc with sheave, and sheave is fixedlyed connected by spline with shift lever.
When electric vehicle gearshift beginning, entire car controller sends instruction allows shift motor driver slot wheel mechanism, Geneva mechanism drive the gearshift driving lever, makes speed changer fall back on neutral position; When arriving neutral position, neutral gear signal on the selector is effective, after entire car controller is accepted this signal, stop the rotation of gear shifting motor, though shift motor is because inertia can continue to change forward an angle, because the indent locking arc of sheave is by the evagination locking arc card master of dial in the Geneva mechanism, sheave is motionless, make selector fork be parked in the neutral position accurately, thereby accurately finish the gear shift action.

Embodiment
As shown in Figure 1, this gear-shifting actuating mechanism mainly is made up of gear shifting motor 1, Geneva mechanism and shift lever 4.Wherein gear shifting motor adopts brush direct current motor.Geneva mechanism is made up of sheave 2 and dial 3.The annexation of these mechanisms is as follows: gear shifting motor 1 directly links to each other with the dial 3 of Geneva mechanism by output shaft, dial 3 in the Geneva mechanism matches with evagination locking arc by indent locking arc with sheave 2, and sheave 2 and shift lever 4 are fixedlyed connected by spline.
During the gearshift beginning, shift motor 1 driver slot wheel mechanism, Geneva mechanism drive gearshift driving lever 4, under the cooperation of sheave 2 and dial 3, make speed changer fall back on neutral position exactly, finish gear shift action subsequently then.
