Embodiment Construction

[0032] In view of this, the core of the present invention is to provide an electric drive shift actuator to simplify the structure and reduce the production cost. Another core of the present invention is to provide an automobile with the above-mentioned electric drive gear shift actuator.

[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] like Figure 1-Figure 5 As shown, the present invention discloses an electric drive gear shift actuator, which includes a motor 1, a reducer 2 and a shift shaft 3 that are connected in sequence, and also includes: a first one-way clutch 4, a second one-way clutch 8 , The first shift drum 7, the second shift drum 9, the first shift fork 11 and the second shift fork 13. Wherein, the inner ring of the first one-way clutch 4 and the inner ri...

Abstract

The invention discloses an automobile and an electrically driven gear-shifting execution device. The electrically driven gear-shifting execution device comprises a motor, a speed reducer and a gear-shifting shaft, wherein the motor, the speed reducer and the gear-shifting shaft are in transmission connection in sequence. The electrically driven gear-shifting execution device also comprises that aninner ring of a first one-way clutch and an inner ring of a second one-way clutch are both in transmission connection with a gear-shifting shaft, and in addition, power transmission directions are opposite; a first gear-shifting drum is connected with an outer ring of the first one-way clutch; a first shifting fork is in sliding connection with the slideway of the first gear-shifting drum; a second gear-shifting drum is connected with an outer ring of the second one-way clutch; and a second shifting fork is in sliding connection along the slideway of the second gear-shifting drum. Since two one-way clutches with opposite power transferring directions are arranged, a situation that only one one-way clutch transfers power during driving can be guaranteed, i.e., different gears are switchedthrough a way that only one shifting fork acts. Since the first shifting fork and the second shifting fork are independently controlled through the corresponding gear-shifting drum, independent actionis realized, and a combination of various positions can be realized, i.e., multiple gears can be realized. Since only one motor and only one speed reducer are used, a whole system has low cost, a small space and is flexible in arrangement.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile and an electric drive gear shift actuator thereof. Background technique [0002] Due to the advantages of low cost and fast shift response, electric drive shifting technology has been more and more widely used in recent years. The shift mechanism based on the shift drum device has been popularized in hybrid transmissions and dual clutch transmissions. [0003] At present, in the shifting mechanism based on the shifting drum, each motor usually drives a shifting drum, and the slide on the shifting drum pushes the slider to move, and then drives the shifting fork to realize the shifting of gears. For hybrid transmissions using combined synchronizer shifting technology, some gears require two synchronizers to transmit power at the same time, and there are many combinations of synchronizer positions, which requires two or more shift drums, corresponding to two One ...
