1, Watt connecting rod is to add a push rod to the left and right of the rear suspension respectively, and the two push rods are connected through a lever mechanism and interact with each other to limit the range of motion. It can reduce the compression and extension of the suspension on both sides and ensure the vertical movement relationship between the car body and the axle. The stress on both sides of the suspension is more uniform, and the roll of the vehicle will be significantly reduced, especially in extreme cases such as turning, which can greatly improve the stability of the car body.
2. Watt connecting rod was originally invented by British inventor james watt, but it was Opel who combined torsion beam suspension with Watt connecting rod and applied for patent registration.
