Embodiment Construction

[0065] like figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 as shown, figure 1 It is a structural schematic diagram of the second-speed epicyclic gear train transmission of the first embodiment of the transmission of the present invention, which belongs to automatic gear shifting and is suitable for assembly and use of motors below 2 kilowatts.

[0066] The second gear epicyclic transmission is epicyclic gear transmission, including casing 4, two-way face gear clutch 5, inner ring gear 315, planetary gear 82, sun gear 69, planet carrier 62, input shaft 1, output shaft 6, machine The shell 4 includes a cylindrical shell, a left end cover, and a right end cover. The right end of the planetary carrier 62 is arranged and fixed in a circle with three planetary wheel shafts. The center of the planetary carrier is assembled and fixed with the outer circle of the right end of the output shaft 6. The left end and the output shaft are assembled and rotated through the bea...

Abstract

The invention discloses a transmission. The transmission comprises a control system, a transmission switching system and a gear transmission system. The transmission is characterized in that accordingto the transmission switching system, a travel gear-locking device and a bidirectional multi-piece type friction clutch cooperate to realize gear shifting or a reverse motion device and a bidirectional end surface toothed clutch cooperate to realize gear shifting; according to the travel gear-locking device, a sliding sleeve seat is assembled on an input shaft, an outwards-convex stop ring of thesliding sleeve seat and a stop ring are provided with lug assembling cranks; a large sliding sleeve is assembled on the sliding sleeve seat; a shifting ring is assembled on the large sliding sleeve;the large sliding sleeve is provided with a pull claw matched with force arms of the cranks; the large sliding sleeve is provided with a push claw matched with an outwards-convex claw; buckling clawsare assembled at two ends of a short groove of an input groove through hinge pins and springs; the cranks are matched with the buckling claws; a guiding rod is assembled on the sliding sleeve seat tobe connected with the clutch; and the shifting ring is connected with the control system. The transmission is applied to an electric vehicle, the gradeability can be enhanced, and the endurance mileage can be increased.

Description

technical field [0001] The invention relates to a transmission in the drive system of an electric vehicle, in particular to a gear shifting device for a drive axle differential motor of the electric vehicle, which belongs to the technical field of mechanical transmission. Background technique [0002] The manual shifting operation of the differential motor of the drive axle of the existing electric vehicle is cumbersome, which affects driving safety; the motor-operated automatic shifting takes a long time, the power of the vehicle loses continuity, and the safety and reliability of driving is poor. [0003] In the existing technology, the Chinese invention patent application (application number: 201710885468.7) discloses an automatic transmission. The clutch cooperates to realize gear shifting; its end tooth clutch is also equipped with a synchronizing device. The cooperation between the cone clutch and the jaw clutch includes a disc base, an outer coupling body and an inne...
