Problems solved by technology

Some use a low-speed single-motor drive axle to drive the two rear wheels and drive the two front wheels. The biggest disadvantage of the low-speed single-motor drive axle is that the unsprung mass is too large, which reduces the ride comfort and handling stability.
Affected by the addition of drive motors, gearboxes and other assemblies, the curb weight of the chassis is larger, the load weight is smaller, the axle

Embodiment

[0030] A series platform for multi-axis distributed drive pure electric vehicles, including a frame and two or more double-motor drive axles arranged under the frame, specifically two-axis distributed drive chassis platforms assembled into 4×2 and 4×4 drive forms; three Axis distributed drive chassis platforms are assembled into 6×4, 6×6 drive forms; four-axis distributed drive chassis platforms are assembled into 8×4, 8×6, 8×8 drive forms. The front axle can also be designed as a non-drive axle, eventually forming a series platform for pure electric vehicles with M×N multi-axis distributed drive.

[0031] The two-axis distributed drive vehicle series platform is specifically divided into electric two-axis full-drive chassis platform (4×4) and electric two-axis single-drive chassis platform (4×2).

[0032] Three-axis distributed drive vehicle series platform, if the front axle is designed as a non-drive steering axle, and the rear four wheels are driven by two drive axles, a 6...

Abstract

The invention discloses a multi-axle distributed driving pure electric vehicle seriation platform. The platform is a distributed multi-purpose pure electric vehicle seriation common platform composed of at least two double-motor driving axles and can be used for pure electric trucks, passenger cars and self-propelled trailers. The distributed driving chassis platform is composed of multiple double-motor driving axles. Transmission ratios of axles on the driving axles can be different, transmission switching control is conducted through a whole vehicle controller and a motor controller, optimizing control is conducted according to the requirements on resistance of various road surfaces and the driving speed, and the work efficiency of motors can be fully exerted. Multiple sets of motors, battery packs and controllers are dispersed and parallelly used, the safety of a power supply can be improved, and the system cost can be reduced.

Description

technical field [0001] The invention relates to the fields of motor drive technology, multi-shaft drive technology, multi-motor variable speed technology and new energy vehicles. Background technique [0002] With the development of new energy vehicles, the social demand for new pure electric vehicles such as pure electric buses, pure electric trucks and pure electric logistics vehicles is increasing. At present, the pure electric vehicles produced by most electric vehicle manufacturers are mostly driven by 4×2 models, with two drive wheels among the four wheels, driven by the rear axle or the front axle. [0003] Some use electric motors instead of engines to provide power, and the chassis is refitted from the traditional second-class chassis of automobiles. Some use a low-speed single-motor drive axle to drive the two rear wheels and drive the two front wheels. The biggest disadvantage of the low-speed single-motor drive axle is that the unsprung mass is too large, which ...
