Problems solved by technology

Cars need to brake frequently when driving on urban roads. During the frequent braking process, most of the kinetic energy is converted into heat energy through the friction of the brakes and consumed, resulting in huge energy loss and waste, which does not meet the energy saving and emission reduction proposed by our country. requirements

Abstract

The invention discloses an automotive braking energy recovering device. The outer lateral surface of a brakecaliper is provided with a notch, a friction wheel is arranged in the notch, projecting shafts at two ends of the friction wheel are arranged in holes of rolling bearings respectively, a hydraulic cylinder is fixed on an automotive chassis and arranged in a gap between a brake disc and the inner side of the brakecaliper, a piston is contacted with the inner lateral surface of the brakecaliper, the outer cylindrical surface of the brakecaliper is provided with a generator, and the shaft of the generator is provided with a first bevel gear meshed with a second bevel gear on the shaft at one end of the friction wheel. The device can recover most energy used in the braking of an automobile to supply power for vehicle-mounted electric appliances. Meanwhile, as most energy is converted into electric energy, heat energy generated during friction is reduced greatly, the temperature of the brake disc is reduced, and the service life of the brake disc is prolonged.

Description

technical field [0001] The invention relates to an automobile braking energy recovery device. Background technique [0002] my country's "Eleventh Five-Year Plan" outline proposes that during the "Eleventh Five-Year Plan" period, the energy consumption per unit of GDP will be reduced by about 20%, and the total discharge of major pollutants will be reduced by 10%. This is a major measure to implement the scientific outlook on development and build a harmonious socialist society; it is an inevitable choice for building a resource-saving and environment-friendly society; it is the only way to promote economic structural adjustment and change the growth mode; Inevitably required. However, there are many intersections and many vehicles on the roads of modern cities. Cars need to brake frequently when driving on urban roads. During the frequent braking process, most of the kinetic energy is converted into heat energy through the friction of the brakes and consumed, resulting in...
