Problems solved by technology

For multi-speed AMT gearboxes, there are power interruptions, large neutral loss, weak electric braking energy recovery, difficulty in fast arbitrary gear switching, long shift time, and high cost; for multi-speed wet friction pair AT gearboxes, Although the problem of power interruption and arbitrary gear switching is solved, there are problems such as great idling loss after the gear shift clutch is disconnected, high cost, and high energy consumption for gear shifting.

Abstract

The invention discloses a hydraulic caliper disc type automatic four-speed drive device for a pure electric vehicle. The hydraulic caliper disc type automatic four-speed drive device for the pure electric vehicle comprises a drive motor, an elastic damper, a front compound planetary transmission device, a back compound planetary transmission device, four groups of brake caliper assemblies, a controller, a battery pack and a hydraulic control unit, wherein an output shaft of the drive motor is connected with the elastic damper; an output shaft of the elastic damper is connected with the front compound planetary transmission device; an output shaft of the front compound planetary transmission device is connected with the back compound planetary transmission device; the back compound planetary transmission device is connected with an output shaft; the front compound planetary transmission device and the back compound planetary transmission device are connected with the brake caliper assemblies respectively; the controller is electrically connected with the battery pack, the drive motor and the hydraulic control unit separately; and the hydraulic control unit is connected with the brake caliper assemblies separately. The hydraulic caliper disc type automatic four-speed drive device has the advantages of unpowered discontinuous shifting, arbitrary gear switching, small no-loadhollowloss, rapidness in shifting response, low shifting energy consumption, low cost and the like.

Description

technical field [0001] The invention relates to the field of driving devices for vehicles, in particular to a hydraulic clamp disc automatic four-speed driving device for pure electric vehicles. Background technique [0002] With the increasing demand of pure electric vehicles for high power performance, high power saving and cost reduction of pure electric drive, multi-speed automatic variable speed drive device has become a key to solve the above problems. At present, the existing multi-speed transmission devices on the market mainly adopt the AMT scheme and the AT scheme. The former mainly adopts electronic execution of shift fork gear selection and shifting, and the latter mainly adopts wet friction plate hydraulic execution of shifting. For multi-speed AMT gearboxes, there are power interruptions, large neutral loss, weak electric braking energy recovery, difficulty in fast arbitrary gear switching, long shift time, and high cost; for multi-speed wet friction pair AT ge...
