Problems solved by technology

Among them, the friction clutch is widely used, but because the friction clutch mainly transmits torque through the friction force between the friction plates, it has problems such as large loss of friction plates and limited transmission torque.
Moreover, the on-off time of the clutch during the shifting process of the car will affect the feeling of driving frustration

Abstract

The invention provides a mechanical rigid-flexible gear shifting device. Synchronization of clutches and gears is realized by the friction force of friction plates under the condition of small torque, power is transmitted through splines under the condition of large torque, and a parallel type structure and a serial type structure can be arranged. The gear shifting device specifically and structurally comprises a duplex gear, clutch shells, friction plates, tooth-shaped spacers, springs, spline seats, push column seats, nuts, a gear-shifting direct-current motor, a spline shaft, another duplex gear and integrated screw gears. According to the mechanical rigid-flexible gear shifting device, different contact or motion relations between the two sets of friction plates and the tooth-shaped spacers, the two sets of duplex gears as well as the spline seats are controlled by the rotating direction of the gear-shifting direct-current motor, and therefore the input torque source is switched, and torque output is carried out in different output modes in a parallel type and a serial type.

Description

technical field [0001] The invention belongs to the technical field of automobile power systems, and in particular relates to a mechanical rigid-soft shift device. Background technique [0002] At present, the shifting device of an automobile mainly adopts the structure of a combination of a clutch and a synchronizer, and the clutches mainly include friction clutches, hydraulic torque converters (hydraulic couplings), and electromagnetic clutches. Among them, the friction clutch is widely used, but because the friction clutch mainly transmits torque through the friction force between the friction plates, it has problems such as large friction plate loss and limited transmission torque. Moreover, the on-off time of the clutch during the shifting process of the car will affect the driving frustration. Therefore, the present invention proposes a mechanical rigid-flexible shifting device, which realizes shifting without power interruption through two parallel clutches or a seri...
