Braking kinetic energy regenerating hydraulic retarder for automobile

Abstract

The invention discloses a braking kinetic energy regenerating hydraulic retarder for an automobile. The hydraulic retarder is an oil pump and hydraulic system arranged on power takeoff windows for gearboxes of large and medium automobiles. The hydraulic retarder not only has functions of the hydraulic retarder for the automobile, but also can recycle kinetic energy to be abandoned when the automobile brakes. The hydraulic retarder is characterized in that: the hydraulic retarder is connected in parallel with main transmission of the automobile, so the hydraulic retarder is convenient to joint and separate; remarkable energy-saving effect is achieved; energy is released and more force is applied when a vehicle is started, so the working condition of an engine is improved and the emission of harmful gas is reduced; starting speed can be increased and running efficiency is improved; mechanical rigid braking is replaced by flexible hydraulic retarding, so riding comfort is improved, the service lives of vehicle braking and a braking system are prolonged, and the safety performance of the vehicle is enhanced; and conventional mature hydraulic technology and hydraulic components produced in a large scale are adopted, so the system is simple and reliable, has low manufacturing cost, and is easy to popularize and apply.

Description

Technical field: [0001] The automobile braking kinetic energy regeneration hydraulic retarder of the present invention is an oil pump and a hydraulic system installed on the power take-off window of a large and medium-sized automobile gearbox. It not only has the function of an automobile hydraulic retarder, but also can recover automobile braking The kinetic energy that is about to be discarded and reused. It belongs to the field of mechanical technology. Background technique: [0002] Automobile braking system is one of the most important systems in the safe driving of automobiles. With the development of engine technology and the improvement of road conditions, the driving speed (that is, the driving kinetic energy) of the car has been greatly improved, and the traditional friction disc brake device is increasingly unable to meet the requirements of driving. For various types of vehicles operating in hilly and mountainous areas, due to frequent or long-term use of the s...

AI Technical Summary

Problems solved by technology

[0003] At present, all kinds of retarders (eddy current, hydraulic, etc.) actually used at home and abroad convert the kinetic energy (or potential energy) of the car into heat energy and emit it into the air in different ways. The kinetic energy of the car depends on consuming various precious energy sources. It is a pity to lose this energy in vain.

[0004] It should be pointed out that hydraulic hybrid vehicles that can recover and reuse the kinetic energy of vehicles during braking have been initially applied in urban buses, garbage trucks and express vehicles that require frequent braking and starting, and many technical solutions have emerged. , such as patent No. 87100344, ZL88214287.9, ZL200620044935.0, ZL200620044934.6, ZL200720073344.0, etc., although they show the role of hydraulic retarder to a certain extent, they can not perfectly replace the current available for more Fanghe's relatively advanced hydraulic retarder
