Abstract

The invention relates to the technical field of automobile detecting equipment, in particular to a damper fatigue test device driven by linear motors. The damper fatigue test device comprises an outerframe, a driving mechanism and a functional accessory; the outer frame comprises a base, a middle partition plate and a top plate; the base is provided with a plurality of foundation bolts, and a buffer sleeve sleeves the bottom of the base, is of a hollow structure, and is filled with a buffer solution; the driving mechanism is mounted on the base and comprises two sets of motion modules in thevertical direction, wherein the two sets of motion modules are composed of the linear motors; and the functional accessory comprises a first clamp arranged on the top plate, and a second clamp mountedon the middle partition plate. According to the full-electric driving damper fatigue test device driven by the linear motors, no friction exists between motion parts, the life is long, collision is avoided, oil stains are avoided, noise is low, the working efficiency is high, the energy loss is less, the electric energy loss is lowered, and the damper fatigue test device can be widely suitable for testing indicator characteristics and speed characteristics of dampers of vehicles such as automobiles and motorcycles.

Description

technical field [0001] The invention relates to the technical field of automobile testing equipment, in particular to a shock absorber fatigue test device driven by a linear motor. Background technique [0002] With the rise of new energy vehicles, automobile OEMs have put forward new high standards for component supporting companies, laboratory background noise and test specifications, forcing future test equipment to improve in terms of technical indicators and system solutions. The testing requirements of components are also constantly improving, and the existing shock absorber fatigue testing machines cannot meet the requirements of the industry. The shock absorber fatigue testing machine widely used at present adopts the first-generation mechanical drive technology and the second-generation hydraulic servo drive technology. These two generations of testing machines are noisy and the environment is harsh. [0003] During the inspection process of the hydraulic automobil...
