Hydraulic mechanical continuously variable transmission (HMCVT) is a system combining and hydraulic power flow. The matching design of the source contribute to energy-saving emission reduction vehicles, meet requirements modern society for environmental protection energy-saving. This paper takes pickup truck as research object ratio control strategy self-designed new HMCVT with goal minimizing ...

This article discusses the progress made in developing a new 3D-printed continuously variable transmission (CVT) for an electric vehicle (EV) prototype competing Shell Eco-marathon battery category, global energy efficiency competition sponsored by Shell. The proposed system is composed of polymeric conic gear assembled motor axle and directly coupled to rear tire vehicle. conical shape allows ...
