In the hydraulic-braking era, grease played a relatively marginal role in the braking system. It reduced wear and suppressed squeal; when problems occurred, the worst-case outcome was merely “degraded pedal feel” or “one extra maintenance cycle.” But EMB has rewritten that logic. EMB eliminates the hydraulic lines; the motor directly drives the ball screw to…
The race for the intelligent chassis has officially entered the domain-controller fusion stage this year. The four subsystems—drive, brake, steering, and suspension—are moving from working in isolation to operating under unified command, as the chassis shifts from hardware stacking to system-level integration. At the Changzhou Intelligent Chassis Symposium this past June, test data on this…
A car that pivots on the spot, crabs sideways, or drives diagonally — behind all three maneuvers lies one component: the intelligent corner module. Drive motor, reducer, steer-by-wire, brake-by-wire and active suspension are all packaged into the wheel end, with mechanical coupling left to software: four wheels become four independently controllable actuators. At an intelligent…
The rise of new energy vehicles has driven iterative upgrades across chassis and cabin actuation systems — and led more than a few component manufacturers into a selection trap: carrying over lubricating grease formulated for ICE vehicles, only to encounter abnormal noises, sticking, damaged seals and current anomalies after installation. The root cause lies in…
Beyond the much-watched “three-electric” systems (battery, motor and power electronics), a new energy vehicle carries hundreds of lubrication points throughout the body: chassis EMB/EPB braking systems, EPS steering mechanisms, door checkers, seat rails, window regulators, power tailgates, air-conditioning vents, exterior-mirror folding mechanisms, and more. Operating conditions differ enormously from one location to another, and so…
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,…
Grease is a semi-solid lubricating material made from mineral oil (or synthetic lubricating oil) and thickener. It has multiple functions such as lubrication, sealing, filling gaps and rust prevention. The following are the main factors affecting its timeliness: 1. Packaging factors Packaging has an important impact on the timeliness of grease: Packaging size: Due to…
In motor failure cases, more than half of the failures are caused by the quality of the bearing system; the mildest ones are manifested as bearing noise, and the most serious ones are the disintegration of the bearing, which may cause the motor to sweep the hole or burn the winding; in the process of…
