Embodiment Construction
[0013] Below in combination with the accompanying drawings, take the shift actuator of the five-speed automobile transmission as an example for specific description:
[0014] like figure 1 As shown, a shift actuator of a five-speed automobile transmission includes a motor 1, a double gear 2, a double gear shaft 4, a shift fork, a reversing light switch 10 and a corner position sensor 9, and is characterized in that: The gear reduction mechanism connects the cam gear 3 of the cylindrical cam 8 with three countersunk bolts 18 through the duplex gear 2 (as figure 2 As shown), the other end of the cylindrical cam 8 is connected to the angular position sensor 9. There are three curved grooves on the circumference of the cylindrical cam 8. The waveforms of the three curved grooves are staggered. The first / second gear roller 5 and the fifth / R gear roller 6 (R represents reverse gear), three rollers of third / fourth gear 7 are stuck in three curved grooves respectively, and respectiv...

The invention belongs to automobile transmissions, in particular to a gear-shifting actuating mechanism of an automobile transmission. The gear-shifting actuating mechanism of the automobile transmission comprises an electric motor, a gear retarding mechanism, gear shift forks, a backup lamp switch and a corner position transducer. The gear-shifting actuating mechanism is characterized in that the gear retarding mechanism is meshed with a columnar cam through a gear; the other end of the columnar cam is connected with the corner position transducer; a plurality of curve grooves are formed on the periphery of the columnar cam; the wave forms of the plurality of curve grooves are staggered; and a plurality of rollers are respectively clamped in the corresponding curve grooves and are respectively connected with the shift forks of corresponding gears. In the gear-shifting actuating mechanism, automatic gear shifting is realized by controlling the rotation of a single motor to control the movement of the gear shift forks; and when the gear is at the reverse gear position, the backup lamp switch is driven to work to switch on a backup lamp. The gear-shifting actuating mechanism is ingeniously designed, has quick response, is reliable in working, has relatively low cost, is easy to control and can realize automatic gear shifting.
Description
technical field [0001] The invention relates to automobile transmissions, in particular to an automobile transmission shift actuator. Background technique [0002] At present, AMT (Automatic Mechanical Transmission) usually adds a set of selection and shifting actuators to complete the switching of different gears on the basis of traditional manual transmissions. The selection and shifting actions are completed by a motor respectively. Take shifting from second gear to third gear as an example to illustrate the gear shifting process: the shifting motor picks up second gear → the gear selection motor selects gear → the shifting motor shifts to third gear. During this process, the gear selection motor works once from start to stop. The shifting motor has worked twice from start to stop. The motor needs a certain response time to start, and the components that control the motor also need a certain response time. These response times will prolong the total shift time in a cumula...
