A car’s sense of refinement is something passengers feel first through the suspension. Three years ago, air suspension was the exclusive domain of million-yuan luxury cars; today, domestically produced NEVs priced around 300,000 yuan already feature it in large numbers. At the 2026 Changzhou Intelligent Chassis Seminar, OEMs and suppliers laid out this suspension technology…
Replacing the mechanical link between the steering wheel and the wheels with wires is the biggest change in steering systems since EPS became ubiquitous. At the intelligent chassis symposium in June, suppliers and OEMs were in rare agreement: steer-by-wire has moved from concept validation to scaled mass production, and four-wheel independent steering has opened up…
“GB 21670-2025 Technical Requirements and Test Methods for Passenger Car Braking Systems” took effect on January 1 this year, officially opening the first year of EMB mass production. As recently as last December, forums on Auto Brake Network were still debating who would be the first to put an EMB into a production car. Then,…
Introduction On March 20-21, 2025, ODR participation in the Second International Automotive Chassis and Braking Summit came to a successful conclusion at the Crowne Plaza Shanghai Yingyi. During the conference, more than 500 guests from government departments, colleges and universities, OEMs, brake factories, wire-controlled chassis factories, and parts factories related to the chassis and brake…
The “2025 Second International Automotive Chassis and Braking Summit” will be held in Shanghai, China from March 20-21, 2025, with 30+ technical topics shared and 500+ technical personnel participating. The theme of this summit is to promote the development of the automotive braking and chassis system industry and improve scientific and technological innovation capabilities, covering…
Definition: Grease and synthetic rubber compatibility refers to the ability of grease to maintain the volume and hardness of standard elastomers unchanged when in contact with grease. It is expressed as a percentage of volume change. ① Poor compatibility of grease can cause changes in the elasticity of rubber materials, leading to increased or decreased…
Definition: Grease anti-wear performance refers to the ability of grease to prevent wear on lubricated components in high-load operating equipment. ① For metal machinery, due to the relative motion of metal surfaces, friction causes metal to separate and peel off from the surface, resulting in a loss of weight or changes in the volume and…
Definition: Refers to the ability of grease to resist oxidation during storage or when used under high-temperature conditions. ① The metal soap and base oil components in grease are prone to oxidation during long-term storage or prolonged exposure to high temperatures and air. Oxidation results in grease deterioration, a decrease in dropping point, the formation…
Definition: Refers to the ability of grease’s structural system to resist deformation and flow under mechanical shear forces. ① Mechanical stability is an important performance characteristic of grease and a key factor affecting its service life. ② The mechanical stability of grease mainly depends on the type of thickener and the preparation process. ③ Methods…
Definition: The grease copper corrosion test refers to the ability of grease to protect metal copper sheets from corrosion, which has become one of the main physical and chemical properties. ① The significance of grease copper corrosion lies in determining the corrosiveness of grease to metal and its ability to protect metals from corrosion. This…
