Embodiment Construction

[0036] The present invention will be further described below in conjunction with accompanying drawing.

[0037] 1. Composition of the parallel electric energy storage regenerative braking system of the present invention

[0038] figure 1 As shown, the interface position of the parallel electric energy storage regenerative braking system of the present invention. The power of the existing vehicle engine 1 is transmitted from the engine, and is transmitted to the half shaft 9 through the clutch 2, the speed changer 3, the universal joint 4, the transmission shaft 5, the final drive 6 and the differential 7, and finally the power of the engine is transmitted to the axle shaft 9. passed to the wheel. The present invention is just based on the research on this power transmission route of the vehicle, considering that the passive bevel gear of the final drive (in the rear axle housing 8 of the bus vehicle) has a large idle utilization space, which can be developed and reused.

Abstract

The invention relates to a parallel-type vehicle electrical storage energy regeneration brake system and an energy-recycling method. The parallel-type vehicle electrical storage energy regeneration brake system comprises a motor, a super capacitor bank, an accumulator, a harmonic gear retarding mechanism, a torque synthesis device, an electronic control unit, a harmonic gear retarding mechanism controller, a motor controller and a super capacitor controller. A vehicle used in the energy-recycling method is provided with two sets of brake systems: a brake system of a traditional vehicle and a parallel-type electrical storage energy regeneration brake system. The two sets of brake systems singly or simultaneously run on the vehicle according to vehicle speeds, brake depths and accumulator energy values when the vehicle is braked. Energy is recycled by the parallel-type electrical storage energy regeneration brake system, and the vehicle is simultaneously or singly driven by the engine and the motor when the vehicle is braked. The invention converts mechanical energy dispersed in the brake process of the vehicle into electric energy and recycled to save fuel oil, reduce the emission,lower the brake noise, improve the brake safety and prolong the service life of the brake system.

Description

technical field [0001] The invention belongs to the technical field of vehicle engineering, and in particular relates to a parallel vehicle electric energy storage regenerative braking system and an energy recovery and utilization method. Background technique [0002] Facing the ever-accelerating pace of urban construction and the increasing pressure of environmental protection requirements, and under the environment of high and rising international oil prices, research on energy-saving and emission-reduction technologies for vehicles (especially a large number of urban buses) The development of new energy-saving and emission-reducing products is a research topic of great strategic significance for building a conservation-minded society and an environment-friendly city. Urban public transport vehicles travel through large and small streets all day long, and have the characteristics of frequent stops and stops, waiting for traffic signals, poor road operation, frequent brakin...
