The multi-speed transmission assembly and includes a housing, a two-speed planetary transmission stage, a plurality of clutches and a transmission output member that provides rotary power to the differential input member. The two-speed planetary transmission stage has an input sun gear, which is driven by the motor, and employs a set of planet gears having compound planet gears that provide a gear reduction between the sun gear and the transmission output member. The clutches are employed to control an overall reduction ratio."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Two-speed drive module","description":"A drive module that includes an electric motor, a differential assembly with a differential input member and a pair of differential output members, a multi-speed transmission assembly, which transmits","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9777818","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
