Embodiment Construction

[0011] The structure of the left front wheel power assembly of the power assembly of a new type of electric four-wheel vehicle is: a cylindrical motor 4 for electric vehicles is used to connect a speed reducer 3, and the speed reducer is connected to the secondary differential speed of the chassis of ordinary front-drive fuel vehicles. The constant velocity drive shaft assembly 2 between the engine and the left front wheel 1. The cylindrical motor 4 for the electric vehicle, the speed reducer 3, and the constant velocity drive shaft assembly 2 between the differential and the left front wheel are integrated into a left front wheel power assembly. The powertrain of the right front wheel and the powertrain of the left front wheel have the same structure. The transmission system of a general rear-drive car includes: a gearbox, a differential, and the differential transmits power to the left and right through the left and right constant velocity drive shaft assemblies to the left ...

Abstract

The invention discloses a novel power assembly of an electric four-wheeler, which belongs to a power component of a new energy vehicle chassis and comprises a front wheel power assembly and a rear wheel power assembly, and the power assembly of the electric four-wheeler is formed by integrating a cylindrical motor for an electric vehicle, a speed reducer and a constant-speed driving shaft assembly between a differential of a chassis of a fuel vehicle and wheels.

Description

[0001] Technical field [0002] The invention belongs to a power assembly of a four-wheel electric vehicle, which can be used instead of a hub motor in a four-wheel electric car, is convenient for maintenance, has high power, and overcomes the defects of low power of the hub motor and large mass of the wheel of the entire hub motor. Background technique [0003] With the current technical background, most of the existing electric cars directly use the chassis of gas cars, and a motor is installed in front of the gearbox, which retains a complete set of power transmission systems such as the gearbox, transmission shaft, and differential of the gas car chassis. The mass of the system is high, and it is very energy-intensive to run this transmission system. The existing hub motor electric cars do not have the gearbox and differential of the gas car chassis, but the mass and volume of the hub motor are limited by the wheels and other factors of the vehicle, so the power of the hub...
