Embodiment Construction

[0053] The present invention will be further elaborated and illustrated below in conjunction with the accompanying drawings.

[0054] Refer to attached figure 1 , a distributed wheel-side electric drive powertrain for an electric vehicle, comprising a first wheel 1, a first motor 2, a two-in-one reducer 3, a second motor 4, a second wheel 5, and a second half-shaft assembly 6 , the first half shaft assembly 7. The two-in-one reducer 3 has two symmetrical gear reduction structures inside. The two structures do not interfere with each other and are only installed together through the housing. The two gear reduction structures are mirror images, and the input shafts and output shafts of the two gears are respectively arranged on both sides of the two-in-one reducer 3 . The first motor 2 and the second motor 4 are symmetrically arranged on the left and right sides of the two-in-one reducer 3, respectively, the first motor 2 is connected to the input shaft of the left gear reduct...

Abstract

The invention discloses a distributed-type wheel-edge electrically-driven power assembly of an electric vehicle and a method. In the power assembly, a two-in-one speed reducer is internally provided with two gear speed reducing structures without interference in structure, and the two gear speed reducing structures are integrally mounted through a shell; a first motor and a second motor are symmetrically distributed on the left side and the right side of the two-in-one speed reducer correspondingly and connected with input shafts of the two gear speed reducing structures in the two-in-one speed reducer; a first half shaft assembly and a second half shaft assembly are arranged on the left side and the right side of the two-in-one speed reducer correspondingly, one ends of the first half shaft assembly and the second half shaft assembly are connected with output shafts of the two gear speed reducing structures in the two-in-one speed reducer correspondingly, and the other ends of the first half shaft assembly and the second half shaft assembly are connected with a first wheel and a second wheel correspondingly, and the output shaft and the corresponding input shaft of each gear speedreducing structure in the two-in-one speed reducer are parallel and not collinear; and the whole power assembly is distributed in a mirror-image symmetrical mode along the center of the two-in-one speed reducer of the power assembly. A feasible arranging scheme of the wheel-edge motor-driven power assembly adopted by the electric vehicle has the characteristics of being compact in structure and simple and convenient to mount.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle equipment, and in particular relates to a distributed wheel-side electric drive power assembly and a method for an electric vehicle. Background technique [0002] The driving form of the next generation of vehicles must be the distributed drive of hub / wheel motors, which can improve transmission efficiency, simplify the chassis structure, and improve vehicle power, economy and stability. Compared with hub motors, the application technology of wheel motors is relatively Mature is the first choice to promote the productization of distributed drive electric vehicles. In particular, the high-speed motor is used to drive the wheel, and the motor is smaller in size and lower in cost. However, the use of a high-speed motor requires a deceleration module, which increases the difficulty of the design and manufacture of the deceleration gear and the overall layout of the powertrain. Therefore, th...
