Second-hand car suspension and wheel wear degree rapid detection device

Abstract

The invention provides a second-hand vehicle suspension and wheel wear degree rapid detection device, and relates to the second-hand vehicle detection field, the second-hand vehicle suspension and wheel wear degree rapid detection device comprises a fixing plate and a suspension detection mechanism, the fixing plate is arc-shaped, a plurality of fixing holes are formed in the fixing plate along the circumferential direction, and the fixing plate is fixed on a vehicle body wheel brow through bolts; the suspension detection mechanism is arranged on the fixing plate and comprises a second lifting plate, a water bag and an ejector rod, the second lifting plate is located below the fixing plate, the second lifting plate and the fixing plate are connected through a second spring, the second lifting plate is in an arc shape, a pulley is pivoted to the bottom of the second lifting plate, and a second distance sensor is arranged on the fixing plate. The second distance sensor corresponds to the second lifting plate, a storage module is arranged in the fixing plate, the water bag is arranged on the fixing plate, the ejector rod is arranged on the second lifting plate, and a recording component is arranged on the water bag. The device can detect whether the suspension position is good or not by detecting the up-and-down stroke of the tire in the running process, and detection personnel are helped to make a judgment.

Description

technical field [0001] The invention relates to the technical field of second-hand car detection, in particular to a device for quickly detecting the wear degree of the suspension and wheel of a second-hand car. Background technique [0002] The car suspension system refers to the entire support system composed of springs and shock absorbers between the car body and tires. The proper function of the suspension system is to support the body and improve the riding experience. Different suspension settings will give the driver different driving experiences. Suspension system, seemingly simple in appearance, integrates various forces and determines the stability, comfort and safety of a car. It is one of the most critical components of a modern car. However, with the continuous increase of the service life of the car, the spring in the car suspension is repeatedly shortened and elongated for a long time, which will cause the spring in the suspension to become soft and insuffici...

Problems solved by technology

However, with the continuous increase of the service life of the car, the spring in the car suspension is repeatedly shortened and elongated for a long time, which will cause the spring in the suspension to become soft and insufficient in elasticity, which will lead to the deterioration of the effect of the entire suspension system, and the suspension system. The degree of elastic support of the spring in the vehicle can only be checked by the driver's feeling during driving or after the vehicle is fully jacked up.

When inspecting used cars, it is often impossible to find a car repair shop to jack up the car for inspection. You can only rely on the driver to drive through some speed bumps and other roads to feel the quality of the vehicle's suspension system. Subjective judgment without accurate numerical support, thus causing certain difficulties in detection
