An automobile braking kinetic energy recovery device

Abstract

The invention discloses an automobile brake energy recycling device. The recycling device comprises an air filter and two compressors, wherein the two compressors are arranged on the wheels of an automobile and are coaxially operated with automobile wheel hubs, the two blade type compressors are connected in parallel through a pipeline; the air filter is communicated with the air inlet ends of the two blade type compressors through a main pipeline, a branch pipe is connected in parallel between the air inlet end of the main pipeline and the two blade type compressors, and the air filter is communicated with a gas storage cylinder through the branch pipeline; a pipeline at the air outlet end of the main pipeline is divided into two ways, the first way of pipeline is communicated with outside air, and the second way of pipeline is communicated with the gas storage cylinder; and the air outlet ends of the two blade type compressors are communicated with the gas storage cylinder through the second way of pipeline; the main pipeline between the branch pipe and the main pipeline, the branch pipe, the second way of pipeline at the air outlet end of the main pipeline, and the first way of pipeline at the air outlet end of the main pipeline are internally provided with an electromagnetic valve, respectively. The device provided by the invention is simple in structure, low in cost, and higher in energy conversion rate.

Description

technical field [0001] The invention relates to an energy recovery and utilization device, in particular to an automobile brake kinetic energy recovery and utilization device. Background technique [0002] After a long period of testing, it was found that the fuel consumption of the car is very large when starting, braking, and driving at low speeds. When driving in urban areas, due to frequent starting and braking, it generally accounts for more than 30% of the total output power of the engine, which means A large amount of energy is consumed excessively. At present, Shanghai Jiaotong University Shenzhou Automobile Design and Development Co., Ltd. has developed the "Automotive Brake Kinetic Energy Recovery Fuel-saving Booster Device", which uses the mechanical device installed on the power take-off window of the automobile gearbox or installed on the drive shaft and simple hydraulic pressure System, during the braking process of the car, the inertia of the car drives the o...

AI Technical Summary

Problems solved by technology

The structure of the device is relatively complicated, the cost of the device is too high, and the maintenance during use is difficult

The other is "Electric Vehicle Braking Energy Recovery Device", which converts the kinetic energy during braking into electrical energy for storage, and this device can only be used on electric vehicles and electric bicycles

"A system and method for recovering kinetic energy from vehicle deceleration inertia" is to convert kinetic energy into electric energy for storage, and the structure of the device is complex and the manufacturing cost is high

[0003] The above-mentioned devices all have the disadvantages of relatively complex structure, high maintenance and use costs, and the utilization rate of energy after conversion is reduced.

These shortcomings make the device unable to be popularized and practical on a large scale.
