Maurice Hudaille, a Frenchman invented the first-ever shock absorber by using the valving of hydraulic fluid that has outstanding cushioning characteristics and patented his invention in 1907 that became a standard component on Ford Model A in the year 1927.<\/p>\n\n\n\n
Several developments took place\nin recent years in the field of dampers. All modern dampers are\nvelocity-sensitive devices with hydraulic damping. Hydraulic damping works on\nthe principle that faster the automobile\u2019s suspension moves, the higher\nresistance it offers as a result of which it decreases the sway or roll and\nbounce rate.<\/p>\n\n\n\n
A paper titled \u201cRecovering energy from shock absorber motion on\nheavy-duty commercial vehicles<\/a>\u201d reveals a different sort of shock absorber.\nNamed Genshock, it improves fuel efficiency by about 1% by generating electrical\nenergy from the linear movement of suspension due to uneven roads which can be\nfurther utilized in the vehicle to decrease alternator\u2019s load.<\/p>\n\n\n\n Several patents as well have been\nfiled in recent years that demonstrate the improvements in dampers. Some of the\nimportant ones are listed below. <\/p>\n\n\n\n Patent RU191194U1<\/a> titled \u201cDynamic vehicle vibration damper\u201d\ndiscussed the more reliable and conventional dynamic vibration damper having\nthe capability of changing the resonant frequency as the car design changes. <\/p>\n\n\n\n Patent CN208778576U<\/a> titled \u201cDamping device on body of a\nmotor car\u201d reveals a shock absorber that increases the comfort level of the rider\nand reduces the noise. It slows down the vibration sensation and abrasions by\ninstalling different components such as rubber tube drum, stainless steel\nspring inside the damper, spacing block in it.<\/p>\n\n\n\n Recently filed patent application\nCN109488152A<\/a> – \u201cA kind of rotary damper and a kind of\nelectric pushrod device,\u201d a rotary damper is disclosed in which the area exposed\nto the frictional force is larger and the length of this radial damper is allowed\nto be made small.<\/p>\n\n\n\n
