Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle technology, and relates to a steerable angle drive system, specifically to a steerable angle drive system assembly bench and testing system. Background Technology

[0002] With the development of electric vehicles, electric drive vehicles are divided into centralized drive and distributed drive systems based on the different arrangements of their power systems. Distributed drive vehicles allow each wheel to have an independent power source control; each motor can independently control each wheel, enabling individual wheel driving, braking, forward movement, and reversing. Compared to centralized drive vehicles, distributed drive vehicles have advantages such as a shorter drive chain and lighter curb weight, resulting in superior maneuverability, reliability, economy, and road adaptability. Therefore, distributed drive technology is currently an important technological route for electric drive systems.

[0003] Angle drive systems are a type of distributed drive system. Based on a drive-by-wire chassis, they integrate the drive, braking, steering, and suspension systems into one unit. Drive-by-wire chassis eliminates the mechanical and hydraulic physical connections between the steering and braking systems and the steering wheel and pedals found in traditional chassis, significantly improving the precision and responsiveness of intelligent control. They are highly integrated and modular. Each angle drive system acts as a "foot" in the electric vehicle, allowing independent control based on environmental conditions. Even if one or more angle drive systems fail, the vehicle can still function using the remaining healthy wheels, greatly enhancing maintainability and reliability.

[0004] As a more advanced form of angle drive system, the steerable angle drive system is highly integrated. This high level of integration places higher demands on the testing and verification of the steerable angle drive system, requiring tests on its overall strength and stiffness, and verification of its structural stability and functional reliability under extreme and endurance conditions.
