Description

Vehicle Suspension K&C Characteristic Test Structure

technical field

The utility model relates to the technical field of vehicle suspension testing, in particular to a vehicle suspension K&C characteristic testing structure.

Background technique

K&C characteristics are the basis of vehicle chassis design. K&C characteristics are divided into K (Kinematic) characteristics and C (Compliance) characteristics. K characteristics are the suspension kinematics characteristics. The action of the guiding mechanism such as the swing arm causes the characteristics of the angular displacement and linear displacement of the wheel plane and the wheel center point, such as the relationship between the wheel jump displacement and the lateral displacement of the wheel center; the C characteristic is the elastic kinematics characteristic of the suspension, which refers to the ground The characteristics of the angular displacement and linear displacement of the wheel plane and the wheel center caused by the force and moment acting on the tire, such as the relationship between the wheel lateral force and the lateral displacement of the wheel center.

The acquisition of vehicle K&C characteristics needs to be tested on the K&C test bench. The K&C test stand includes a central platform and a fixture fixed on the central platform. After the vehicle is placed on the K&C test stand, the bottom of the vehicle needs to be fixed to the central platform of the K&C test stand through the fixture. When the lower body beam at the bottom of the vehicle has a flange, the flange can be clamped by the clamp to fix the vehicle on the central platform; when the vehicle has a frame without flange, it can be welded at the longitudinal beam of the frame Flip the flange, and then use the clamp to clamp the flange to fix the vehicle on the central platform.

For models with an all-aluminum body structure, due to the special manufacturing process, there is no flange at the bottom of the vehicle, and the vehicle cannot be fixed on the K&C test bench. The flange is fixed to the bottom of the vehicle by welding or riveting, and the original structure of the vehicle will inevitably be damaged during the welding and riveting process. For high-end models that cost tens of millions, the gains outweigh the losses, so obtaining K&C features without damaging the body has certain economic value.
