Description
Technical field
The utility model relates to the Development of HEV Technology field, is specifically related to can be applicable to energy storage and the actuating device of hybrid vehicle.
Background technology
Facing mankind fossil energy and is petered out and depend on the ecological deterioration two that fossil energy causes unduly and challenge greatly; the petroleum-based energy of take is absorbed in the Double jeopardy of resource and environment as the fast development of the orthodox car of power just makes the mankind, and the new-energy automobile that therefore develops energy-conserving and environment-protective becomes the development tendency of industry gradually.
Hybrid vehicle (HEV) is a kind of by driving engine and the common vehicle driven of electric system, the mainstream development direction that meets environment-friendly high-efficiency, different with power delivery mode according to propulsion source quantity, be divided into tandem type, parallel connection type (PHEV) and hybrid type.Energy storing device is mainly storage battery, super capacitor, fuel cell, inertial flywheel, hydraulic accumulator etc., and accumulated energy flywheel can not bring environmental pollution when discarded as storage battery, and environmental-protecting performance is better.
The braking of automobile is to realize by the friction between brake disc and brake clamp or brake wheel and brake shoe brake cheek.In this process, car load kinetic energy dissipates by the form of friction with heat, causes the waste of energy.Particularly in the operating mode of city, due to traffic congestion and transport administration needs, vehicle need to accelerate repeatedly, slow down, and the energy that braking consumes consumes in gross energy and occupies sizable ratio at vehicle.
Braking energy feedback is very important means that improve automobile energy efficiency, it typically refers to electronlmobil (for example pure electric automobile and hybrid vehicle) in deceleration or descending process, under the prerequisite that guarantees deceleration and stopping performance, the inertia energy of running car is passed to motor by driving system, motor is with power generation mode work, for closed-center system charges, thereby realize the feedback utilization of braking energy.Braking energy feedback can promote the continual mileage of electronlmobil, reduces the weight of on-vehicle battery.In addition, also can reduce the wearing and tearing of brake bush.
