Embodiment Construction

[0012] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.

[0013] Such as figure 1 As shown, the car co-rotating arm type double planetary row driving device is mainly composed of a motor 4, a co-rotating arm double planetary row and high and low speed brakes. Co-rotating arm double star row, motor 4, motor shaft 3, rotating shaft 10, and high-speed shifting brake disc 1 are installed coaxially in sequence.

[0014] The motor shaft 3 is a hollow shaft structure, the rotating shaft 10 passes through the motor shaft 3, and the h...

Abstract

The invention discloses an automobile co-rotating arm type double planetary row driving device. A driving machine drives an output shaft, and at least two stages planetary rows are in transmission connection between the driving machine and the output shaft. The driving machine is transmitted to the output shaft through the two stages planetary rows, and when the corresponding two sets of brakes are selected to be closed and released, two speed ratio driving modes, neutral modes and parking modes are correspondingly realized. The automobile co-rotating arm type double planetary row driving device has the advantages of simple transmission structure, unpowered intermittent gear shifting, arbitrary gear shifting, minimal neutral loss, rapid gear shifting response and the like, and is particularly suitable for a driving device with an automatic gear shifting function of an electric vehicle.

Description

technical field [0001] The invention belongs to a vehicle power system, in particular to a driving device applied to an automobile. Background technique [0002] With the continuous improvement of the vehicle's demand for high power, high power saving and cost reduction of the powertrain, the use of a two-speed drive device has become a key to solve the above problems. At present, most of the drive schemes on the market adopt single-motor direct drive mode and multi-speed transmission with single motor and small speed ratio difference. Among them, multi-speed automatic transmission mainly adopts AMT scheme and AT scheme. Gear shifting, the latter mainly uses wet friction discs to perform gear shifting hydraulically. For multi-speed AMT gearboxes, there are power interruptions, large loss in neutral gear, weak electric braking energy recovery, difficulty in fast arbitrary gear switching, small speed ratio difference between gears, long shifting time, and high cost; Although...
