In 2020 a new guideline for CO2 emissions will come into force in the EU. This requires automotive manufacturers to achieve an average fleet target of 95 g/km. To meet this demand, Hirschvogel would like to support the automotive industry as an innovative partner and is working on achieving lightweight design with forging. Great optimization potential using lightweight design exists in the rear axle differential, where large-sized pinions are used. Compared to solid parts, hollow forged pinions hold many advantages which lead to fuel savings in the vehicle and thus to a reduction in CO2 emissions. Hirschvogel is able to contribute to the megatrend of lightweight design with hollow forged pinions and thereby provide support in achieving the ambitious CO2 targets. This means that Hirschvogel can offer its customers a lighter component at reduced costs.
