Embodiment Construction

[0014] Please refer to the attached figure 1 , the wheel hub dual power system electric car of an implementation of the present invention comprises 1, " dragon boat " type vehicle frame 2, the wheel hub motor (A B C D) of bilateral shaft 3, independent suspension front fork 4, independent suspension rear flat fork 5, main battery pack ( E F G) 6. Auxiliary battery pack 7, steering rod 8, controller group 9, AC charging module 10, DC conversion charging module 11, electric power steering 12, electronic differential 13, steering wheel

[0015] The hub motors of the bilateral shafts of the dual power system electric vehicle are respectively installed on the front fork and the rear balance fork. The hub motors (AB) and (CD) are connected to the output ends (14) and (32) of the controller group 6 respectively. (Proximity principle) The controller group is connected with the main battery group (EFG) through the control switch, and the output terminal of the controller group 6 is co...

Abstract

The invention relates to a double-power system electric automobile. The structure of the electric automobile comprises a novel dragon-boat type carframe, a main battery pack, an auxiliary battery pack, two or four bilateral-shaft hub motors, a front wheel front fork suspension steering system, a rear wheel rear bottom fork suspension system, an alternate current charging module, a direct current converting charging module and an electronic differential mechanism. When the automobile runs at an idle speed, the hub motor charges the auxiliary battery pack and the main battery pack through the alternate current charging module and the direct current converting charging module. The service life of the main battery pack and the auxiliary battery pack is prolonged, and the endurance mileage is increased. When the automobile turns around, the output voltage of a steering side controller is automatically decreased under the effect of the electronic differential mechanism, accordingly the revolution speed of the steering side motor is decreased, and safe steering is achieved. Compared with the prior art, the double-power system electric automobile is simple in structure and light and can save energy, and energy can be saved by over 50% compared with a traditional electric automobile. The power form is even in distribution, and guarantees are provided for achieving safe, light and fast,efficient and high-speed operation.

Description

technical field [0001] The invention belongs to the field of electric vehicles, in particular to an electric vehicle with a hub motor dual power system. Background technique [0002] Traditional electric vehicles are mostly designed on the basis of the structure of fuel vehicles, and most of them use differential motors. The differential motors all adopt gear reduction, and front axle or rear axle half shaft transmission. Low mechanical efficiency. In addition, the body structure of traditional electric vehicles is complex and there are many spare parts, so the body is heavy and consumes a lot of power. [0003] Power distribution is uneven. Most traditional electric vehicles use differential motors. Some front differentials, some rear differentials, and some use front and rear differentials. When the car rolls, the other side loses power. Especially when turning, it is extremely easy to rollover. [0004] Due to the uneven power distribution of traditional electric v...
