What Is The Difference Between The Lateral Stabilizer Bar And The Watt Connecting Rod?

Automobile suspension system is divided into independent suspension and non-independent suspension, they have their own advantages and disadvantages. In order to better play the characteristics of the suspension and overcome the shortcomings, people have added some links that play special roles in the suspension, such as the transverse stabilizer bar, the Watt link, the Panhard link and so on. Today we will talk about the structure and function of these links.
Transverse stabilizer bar
Horizontal stabilizer bar, referred to as stabilizer bar, also known as anti-transverse rocker or anti-roll bar, there are places called balance bar. Although the name of this rod is more, it can be seen from the name that its main role is to prevent roll and maintain stability.
To be precise, the transverse stabilizer bar is a part of the automobile suspension system, which is generally fixed in the lower arm of the left and right suspension, and can be regarded as a torsion bar spring arranged horizontally in the chassis of the automobile. It is mainly composed of connecting rod, bushing, bracket, anti-slip ring, etc., which can be divided into passive and active.
Main role
The car passed the bumpy road
When the car is driving on a smooth road, the horizontal height of the left and right wheels is the same, and the lateral stabilizer bar does not work. In the figure below, the red mark is the spring, the blue one is the shock absorber, and the yellow one is the transverse stabilizer bar.
When the car is driving on the convex and concave uneven road surface, the degree of convex and concave road surface encountered by the left and right wheels is different, which will lead to different deformation of the suspension at both ends of the car. At this time, the transverse stabilizer bar body is twisted, producing downward rebound on the right side and upward rebound on the left side, which reduces the compression and elongation of the right and left suspension springs respectively and prevents deformation.
Watt connecting rod
The "Watt link" was originally invented by legendary British inventor and engineer James Watt. This structure is used in torsion beam suspension to reduce the influence of lateral rear wheel forces on the front wheel bundle. It also reduces the centrifugal generated by the lateral force during the turn, so that the force on both sides of the wheel always maintains the most appropriate contact with the road surface to achieve the best adhesion. On the one hand, the driving comfort of the vehicle is improved, and the tracking of the vehicle is strengthened.
"The watt connecting rod is a push rod added to the left and right of the rear suspension, and the two push rods are connected through the lever mechanism, interacting with each other to limit the range of activity, so that the compression and extension amplitude of the suspension on both sides can be reduced to ensure the vertical motion relationship between the body and the axle." The more uniform the forces on both sides of the suspension, the vehicle roll will be significantly reduced. In particular, it can greatly improve the stability of the body in extreme conditions such as turning.
