Problems solved by technology

The utility model patent 200920266912.8 discloses a hydraulic hybrid transmission. On the basis of the engine power drive and transmission mechanism of the traditional automobile transmission, a hydraulic power drive and transmission mechanism is added, so that the engine power and hydraulic power can be used in the starting, acceleration and braking of the car. During the driving process, the vehicle transmission can be smoothly switched, thereby realizing the recovery and release of vehicle braking energy, and achieving the purpose of energy saving and emission reduction of hydraulic hybrid vehicles. However, this transmission cannot recover the no-load energy of the engine when the engine is idling. restricted

Abstract

The invention relates to an idling-energy-recoverable hydraulic hybrid electric vehicle gearbox, which is characterized in that an idling-energy-recoverable transmission mechanism is added on the basis of a hydraulic hybrid electric vehicle gearbox, so that when a vehicle idles, no-load idling energy of an engine is converted to hydraulic energy to be stored in an energy accumulator. The idling-energy-recoverable hydraulic hybrid electric vehicle gearbox applied when the vehicle is started can further improve the energy-saving and emission-reducing abilities of the vehicle, and belongs to the field of hydraulic hybrid electric vehicle gearbox technologies, energy conservation and new energy vehicles.

Description

technical field [0001] The invention relates to a hydraulic hybrid vehicle transmission with recyclable idling energy, which is characterized in that on the basis of the hydraulic hybrid vehicle transmission, a transmission mechanism with recyclable idling energy is added, so that when the vehicle is idling, the idling energy of the engine without load is converted The hydraulic energy is stored in the accumulator and applied at the start, which can further improve the energy-saving and emission-reduction capabilities of the vehicle. It belongs to the field of hybrid vehicle transmission technology, energy-saving and new energy vehicles. Background technique [0002] A hydraulic hybrid vehicle refers to a vehicle in which two different powers, engine power and hydraulic power, are alternately applied to the vehicle, and one of the most effective ways to alternately apply these two powers is to combine the two powers in the vehicle transmission to switch. The utility model p...
