Electric vehicle using multifunctional mount bracket

Abstract

The invention discloses an electric vehicle using a multifunctional mount bracket. A vehicle body is provided with a left longitudinal beam and a right longitudinal beam; the electric vehicle furthercomprises the multifunctional mount bracket; the multifunctional mount bracket is provided with two parallel bracket transverse beams which are arrayed in the front-rear direction, and the bracket transverse beams are perpendicularly fixed to the left longitudinal beam and the right longitudinal beam of the vehicle body; two or more bracket longitudinal beams are fixedly connected between the twobracket transverse beams, and all the bracket longitudinal beams are perpendicular to the bracket transverse beams; and the bracket longitudinal beams are provided with motor mounting structures. Theelectric vehicle has the beneficial effects that the roll and yaw mode and stiffness of the vehicle body can be improved, and the stable mounting position is provided for a motor and an electric driveassembly controller.

Description

technical field [0001] The invention belongs to the field of automobiles, in particular to an electric automobile using a multifunctional suspension bracket. Background technique [0002] Electric vehicles do not use fuel, do not directly produce exhaust gas, do not pollute the environment, and the energy consumption per unit distance is much lower than that of traditional fuel vehicles, so they are increasingly recognized by consumers. It is one of the main development trends of automobiles in the future. At present, as far as most electric vehicles with a front motor are concerned, there is no traditional fuel engine in the cabin, only a motor with much smaller volume and weight, so the connection and fixing method of the motor is relatively simple. Automobile Chinese patent document CN206031113U disclosed "a pure electric car suspension bracket assembly" on March 22, 2017. The suspension bracket assembly includes: a right suspension bracket and a left suspension bracket;...

AI Technical Summary

Problems solved by technology

Although the inventor claims that the present invention improves the support strength of the pure electric vehicle powertrain, it can be found through analysis that in such traditional solutions, the motor is only installed on two longitudinal beams with two shaft ends Therefore, the movement correlation between the two longitudinal beams is not high, and the synchronization is poor, which makes the body more prone to roll, and the two mounting ends of the motor are also more likely to be damaged. The external pull of the two synchronous longitudinal beams leads to poor installation firmness of the motor, and the direction of the power output shaft is prone to jump, resulting in partial slippage of the power system and the integrity of the front of the vehicle body is also affected
