Embodiment Construction

[0016] Such as figure 1 Shown is the basic structure of the vehicle K&C testing machine.

[0017] It is composed of a loading table A, a six-degree-of-freedom measuring mechanism B, a body clamping system C, a wheelbase adjustment system E (the biaxial testing machine also has a wheelbase adjustment system F), and a data acquisition and processing system. The wheel of the tested suspension of the tested vehicle V is supported on the loading table A, the skirt of the body is clamped by the body holding system C, the loading table A applies force to the wheel, and the deformation of the wheel is measured by the six-degree-of-freedom measuring mechanism B .

[0018] Such as figure 2 Shown is the loading table structure of the K&C testing machine.

[0019] The loading platform is composed of three layers of platforms, vertical cylinder A19 and motion platform A14 to form an afterburner assembly that slides along the axial direction of the sleeve A17 with the guide column A6, a...

Abstract

A kinematics and total working condition elastic tester of a suspension bracket comprises a loading platform (A) capable of testing six component forces, a six-degree-of-freedom movement measuring mechanism (B) of a wheel, a vehicle body clamping system (C), a wheel distance adjusting system (E) and a data collecting and processing system, further comprising an axle distance adjusting system (F). A tester for a whole vehicle and a tester for a separated suspension bracket system can be assembled according to different user requirements and different clamping manners so as to satisfy different requirements on the test of the all-directional kinematics characteristic and the total working condition deformation characteristic.

Description

technical field [0001] Suspension kinematics and full working condition elasticity testing machine is the key testing equipment for the integrated adjustment and development of automobile chassis platform performance. It is not only an important test method for chassis platform performance, but also a source of key data for vehicle dynamics simulation design. Background technique [0002] The kinematics and isotropic elasticity of the car's suspension and steering system make the car's tires produce additional motion under the state of beating and stress, and have an important impact on the car's handling and ride comfort. In recent years, several kinds of automobile chassis kinematics and multi-dimensional elastic testing machines with different structures have appeared in the world. The basic principle is to fix the car body, apply all-directional loads on the wheels with a special multi-directional loading mechanism, and measure the deformation of the wheels. [0003] T...
