Problems solved by technology

Since the hub motor is installed inside the wheel, the unsprung mass of the car is increased, which makes the ride comfort and handling of the vehicle worse. In addition, the power and torque of the hub motor are generally smaller than that of the wheel motor, and the car's power is not as good as that of the wheel motor. , and the use of wheel side motor drive, if not properly designed, will also increase the unsprung mass, and at the same time it is difficult to realize four-wheel independent drive and four-wheel independent steering at the same time from the structure

Embodiment Construction

[0059] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0060] like Figure 1-3 As shown, the four-wheel wheel motor provided by the present invention drives the four-wheel independent steering electric vehicle chassis assembly, including: steering motor 110, bogie 200, steering column 210, guide mechanism 300, spring shock absorber assembly 400 and vehicle Rack 800.

[0061] Wherein, the tire 130 and the rim 140 are installed together, and the rim 140 and the hub 150 are connected together by four bolts;

[0062] The steering motor 110 is bolted to the vehicle frame through a flange, and the output shaft of the motor is connected to the bogie 200 through the flange;

[0063] The steering bracket 610 is located under the vehicle frame 800 . The steering bracket drive shaft is connected to the output shaft of the steering motor 110...

Abstract

The invention discloses an electric car chassis assembly capable of achieving four-wheel wheel-side-motor drive and four-wheel independent turning. The electric car chassis assembly comprises a frame, turning motors, turning support arms, turning racks, drive motors, turning standing columns, spring damper assemblies and guide mechanisms, wherein the turning motors are fixed on the frame, the turning support arms can rotate around the output shafts of the turning motors, the turning racks can rotate along with the turning support arms, hubs are rotatably connected to the turning standing columns, the spring damper assemblies are arranged between the turning support arms and the turning standing columns and used for supporting and damping the turning support arms, and the guide mechanisms are used for guiding the movements of the spring damper assemblies. The electric car chassis assembly has the advantages that the wheel-side motors are used to drive an electric car to turn, the wheel-side motors are designed into sprung mass, the running smoothness and power performance of the electric car are increased, and the drive torque among different wheels can be reasonably distributed due to the fact that the wheel-side motors are used to control the drive torque of the drive four wheels.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a chassis modular structure assembly of a four-wheel independently steering electric vehicle driven by a four-wheel wheel-side motor and a four-wheel torque control method for an electric vehicle with a four-wheel wheel-side motor. Background technique [0002] With the deepening of the design concept of electric vehicles and the continuous progress of the electric drive system, engineers hope that the design of electric vehicles will gradually get rid of the thinking constraints of traditional internal combustion engine vehicle design, so there is an electric vehicle that independently drives four wheels with four motors The chassis structure is a four-wheel independent electric drive chassis. Judging from the research status at home and abroad, four-wheel independent drive electric vehicles are mainly driven by hub motors. Since the hub motor is installed inside the wheel, the...
