Description

technical field [0001] The invention relates to the technical field of automobile energy saving, in particular to an automobile brake energy storage-energy release drive device and method. Background technique [0002] The automobile industry started in 1885 when the Germans Daimler and Benz assembled the internal combustion engine on a tricycle and developed to today. An ordinary car is composed of tens of thousands of parts, and its power, transmission, suspension, steering, braking, electrical appliances, and body systems are all modern technologies. For example, the mechanical transmission in the transmission system, through the combination and matching of various gears, realizes the mutual transformation of the vertical axis and the horizontal axis, the transformation of high speed and low speed and the magnitude of torque, the transformation of the direction of motion, and the mutual transformation of one group and multiple groups of rotation... It can Transformation ...

AI Technical Summary

Problems solved by technology

[0005] Electric hybrid vehicles have made some progress in terms of energy saving and emission reduction, but there are many problems: (1) In addition to the vehicle engine, its power system needs to add generators, storage batteries, motors or generators / motors, which occupy a relatively large portion of the vehicle. Large space and weight; (2) The electric energy of the storage battery comes from the external energy source and the on-board engine, which still consumes energy and fuel to a considerable extent; (3) The efficiency in recovering and utilizing the kinetic energy lost when the car brakes and decelerates is limited, Because a) If a special on-board generator is used to "collect" the electric energy generated by the wheel rotation (cutting the magnetic field line) during braking and deceleration and store it in the storage battery, and then use another special on-board motor to start the car, When accelerating, the electric energy obtained from the battery drives the wheels to rotate, and the on-board equipment is more and heavier; b) If a so-called generator / motor is used to complete the above-mentioned work of both generating and driving, although the generator and the motor are theoretically reversible, their The structure is also basically the same, but because of their different tasks and specific requirements, in actual structure, if a well-designed generator is used as a motor, the efficiency is low, and conversely, if a well-designed motor is used as a generator, the efficiency is also low; c) power generation The machine converts mechanical energy into electrical energy, inputs and stores it in the battery, then outputs from the battery, inputs it into the motor, and then converts the electrical energy into mechanical energy. The energy loss in the conversion process is large

Relevant designs often include a series of hydraulic and pneumatic components and circuits that cooperate with each other in this field, which is difficult to actually layout and apply in the limited space of the car
