Two-speed device for rapid gear shifting

Abstract

The invention discloses a two-speed device for rapid gear shifting. The two-speed device comprises a shell, wherein an accommodating cavity is formed in the shell, a rotating shaft is movably installed in the accommodating cavity, one end of the rotating shaft is movably connected with one side of the inner wall of the accommodating cavity through a shaft base, and the other end of the rotating shaft penetrates through the accommodating cavity and extends to one side of the shell; and a first driving wheel and a second driving wheel are fixedly installed on the surface of the rotating shaft and located in the accommodating cavity from left to right in sequence. Through the cooperation of the first driving wheel, the second driving wheel, a first driven wheel and a second driven wheel, a transmission shaft and the rotating shaft have different rotating speed; the first driving wheel is separated from the first driven wheel by moving a pull rod; and the transmission shaft can be connected with the rotating shaft by cooperation of connection sleeve joint and connection insertion joint so as to adjust the rotating speed of the transmission shaft, thus achieving the effect of changing the speed. The speed change device is simple in structure and convenient to operate and maintain.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a two-speed device for quick shifting. Background technique [0002] Gearing refers to the transmission, which is used to change the torque and speed of the engine crankshaft to meet the needs of different driving wheel traction and vehicle speed requirements under different driving conditions such as starting, accelerating, driving, and overcoming various road obstacles. [0003] At present, most of the gears on the market are shifted synchronously by stepping on the clutch and semi-linkage. Such a shifting method has complicated operations and a complicated shifting structure. When damage occurs, it is not easy to repair and maintain. Contents of the invention [0004] The purpose of the present invention is to provide a second-speed device with fast shifting, which has the advantages of fast shifting and convenient shifting, and solves the problem mentioned in the b...
