Abstract

The invention discloses a lateral force detector for four wheels of an automobile, and the lateral force detector includes at least four measuring platforms and a lateral force detection device, wherein the measuring platforms are connected with the lateral force detection device respectively; several measuring rollers are arranged on each of the measuring platforms; the measuring rollers are parallel to wheel axles of the automobile, and are respectively connected with pressure sensors and angular speed sensors; and the pressure sensors and the angular speed sensors are respectively connected with the lateral force detection device to send the pressure and angular speed data of the wheels to the lateral force detection device. The lateral force detector for the four wheels of the automobile can measure the lateral forces of all wheels at a time, is convenient and fast, simplifies the measuring steps, and saves the measuring time.

Description

technical field [0001] The invention relates to the technical field of vehicle detection, in particular to an automobile four-wheel lateral force detector. Background technique [0002] Measuring forces and torques dynamically plays a vital role in automotive development. This is Kistler's core competence. Car manufacturers strive to make every car feature ride comfort and maximum active safety. To meet this requirement, tires and other driving factors need to be adjusted in bench and road tests. Since the tires are the car's only point of contact with the ground, it is critical to analyze the forces and torques transmitted by the tires, as is understanding the dynamic characteristics of the tires and the effect of suspension adjustments. [0003] A typical wheel dynamometer system is a 6-component system that measures roll, traction, and righting moments (Mx, My, Mz) of longitudinal, lateral, and vertical forces (Fx, Fy, Fz). Kistler also offers a single-component rota...
