Abstract

The invention provides a power couple for a parallel hybrid electric vehicle and a control method of the power coupler. The power coupler comprises an engine output shaft gear, an engine transmission gear set, an engine connecting shaft gear, an engine transmission clutch, a volute spiral spring energy storage mechanism, a driving motor connecting shaft, a driving motor transmission clutch, a driving motor connecting shaft gear, a driving motor transmission gear set, a driving motor output shaft gear and an engine connecting shaft, wherein the volute spiral spring energy storage mechanism comprises a reversible ratchet mechanism, a planet carrier, a sun gear, a gear ring, a planet carrier brake, an energy storage mechanism output disc, a sun gear brake, a volute spiral spring, a sun gear clutch and a planet carrier clutch. According to the power couple provided by the invention, the volute spiral spring energy storage mechanism is utilized for achieving a driving start-stop function of an engine, so that energy consumption and pollution emission are reduced, and the vehicle brake energy recovery capability is improved.

Description

technical field [0001] The invention relates to the field of parallel hybrid electric vehicles, in particular to a power coupler for parallel hybrid electric vehicles and a control method thereof. Background technique [0002] The surge of international oil prices and the pressure of world environmental protection have made electric vehicles a new development direction for the automotive industry. Governments around the world also attach great importance to this, not only promulgating strict laws and regulations to limit the environmental pollution caused by automobile emissions, but also introducing policies to encourage and subsidize the development of electric vehicles. The core technology of electric vehicles. Due to the low energy density, high quality, high cost, short driving range and long charging time of current power batteries, the market promotion process of pure electric vehicles is slow. The hybrid electric vehicle has become a hot spot in the development of ...
