[0002] The motor and the rear axle of the former domestic electric vehicle, no matter whether it is three-wheel or four-wheel, are split, that is, the motor is installed beside the rear axle, and there is no clutch and transmission. The torque of the motor cannot be maximized, that is, the torque of the same power increases, and Large size; there is no neutral coasting when the vehicle is running, and it cannot reverse charge and generate electricity, which restricts the rapid development of electric vehicles

Embodiment Construction
[0012] Such as figure 1 As shown, the present invention is further described as follows:
[0013] The electric vehicle uses an integrated drive rear axle, including a differential gear and a motor. The motor is flat and is connected by the motor lower housing 3 and the motor upper housing 4 to form a motor housing. The stator winding 22, The motor magnet 21 and the rotor 12 constitute a motor, and the rotor of the motor is supported on the support shaft 13 at the center of the motor housing through the fifth bearing 14 and the sixth bearing 15;
[0014] The outer end surface of the motor lower casing 3 is concaved to form a housing cavity, and an outer casing 34 is connected to the motor lower casing 3, and a cavity is formed between the outer casing 34 and the motor lower casing 3; the rotor 12 of the motor is provided with an outer shaft The neck protrudes into the receiving cavity, and the outer journal of the rotor is fixed with the driving gear 11; along the radial sides...

The invention provides an integration driving rear axle for an electric vehicle. The integration driving rear axle for the electric vehicle comprises a differential mechanism and a motor. The integration driving rear axle for the electric vehicle is characterized in that the motor is arranged to be of a flat shape, by the aid of ingenious structural arrangement, the motor, a speed change mechanism, an engaging and disengaging gear and the differential mechanism are integrated together so that the integration driving rear axle can be formed, and the speed change mechanism is composed of a high-speed speed change mechanism and a low-speed speed change mechanism. The integration driving rear axle for the electric vehicle has the advantages of being small in size, low in weight, compact in structure, firm and durable. The vehicle can be switched to a neutral gear for sliding at any time in the driving process, reverse charging generation can also be achieved, and accordingly the purpose of energy saving is achieved. After universal joints are additionally arranged at the two ends of the integration driving rear axle for the electric vehicle, an integration driving front axle for the electric vehicle can be formed.
Description
technical field [0001] The invention relates to a driving rear axle for an electric vehicle, in particular to an integrated driving rear axle. Background technique [0002] The motor and the rear axle of the former domestic electric vehicle, no matter whether it is three-wheel or four-wheel, are split, that is, the motor is installed beside the rear axle, and there is no clutch and transmission. The torque of the motor cannot be maximized, that is, the torque of the same power increases, and The volume is large; there is no neutral gear to slide when the vehicle is running, and it cannot reverse charge and generate electricity, which restricts the rapid development of electric vehicles. Contents of the invention [0003] The invention proposes an integrated driving rear axle for electric vehicles, which integrates the motor, the clutch mechanism of the speed change mechanism, and the differential into one body to form an integrated driving rear axle, which has the advantag...
