Embodiment Construction

[0024] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0025] see figure 1 In this embodiment, a double-motor-driven electric vehicle gearbox includes a reducer box, and two parallel shafts are arranged in the box, namely an input shaft 6 and an intermediate shaft 4, and one end of the input shaft is connected to the main motor through an automatic clutch 2 1. The power of the main motor 1 is 12Kw, and the auxiliary motor 5 of 3Kw is installed at one end of the intermediate shaft. The main motor 1 and the auxiliary motor 5 are connected together through a controller 13, a synchronizer and a speed collector are arranged in the gearbox, and a position sensing device is installed at the automatic clutch 2 and the synchronizer. The controller 13 controls the starting and stopping of the auxiliary motor 5 according to the current change of the main motor 1 and...

Abstract

The invention relates to a double-motor driven electric automobile transmission. The double-motor driven electric automobile transmission aims at solving the problems of power compensation and energy recovery of an electric automobile at present, comprises a main motor and an auxiliary motor and is characterized in that the main motor is connected with an input shaft through an automatic clutch, the auxiliary motor is added at the other end of the input shaft or one end of an intermediate shaft, and a synchronizer is arranged on the intermediate shaft. The main motor and the auxiliary motor are associated through a controller, the controller controls starting and stopping work of the auxiliary motor according to the current change of the main motor and the running speed of the automobile, power of the main motor can be reduced, the acceleration and climbing capacity of the automobile can be improved, the auxiliary motor can be further used for electricity generation and energy recovery and is low in power and large in inertia.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a dual-motor driven electric vehicle gearbox. Background technique [0002] Existing electric vehicles all use the main drive motor to recover energy. There are many shortcomings in the energy recovery of the main drive motor, because the drive efficiency of the motor is inversely proportional to the power generation efficiency, that is, the high drive efficiency of the motor means that its power generation efficiency is relatively low. Low, so the drive motor of electric vehicles is mainly based on drive efficiency, and it is very little to recover energy by driving the motor alone. In terms of gearboxes in public documents, a dual power input scheme has been proposed, such as a dual power input gearbox designed with the patent publication number CN103307243A, including driving gears, driven gears, sliding wheels, shift forks, and dual power differentials. Speed ​​gear; driv...
