The suspension K&C (Kinematics & Compliance) test rig is the special equipment for measuring the wheel geometry parameters under various vehicle driving conditions.

It has taken KH more than 12 years to develop the passenger car K&C test rig while the great progress was made on its functions, measuring accuracy, automated operation, reliability and the user friendliness on HMI etc. By now, KH K&C test rig has gained 50% of local market share.

 

Besides the passenger car K&C test rig, KHAT has also launched commercial vehicles K&C test rig (axle load up to 20 tons) to meet the customers demand. In addition, KHAT also provides K&C test service for the vehicle manufacturers. So far, K&C data of more than 140 vehicle models has been collected, which provides strong support for continuously optimizing the quality of K&C test tool.
