Abstract

The invention provides an automobile hydraulic start / stop system. The automobile hydraulic start / stop system comprises two hydraulic mechanisms and a planetary gear speed increaser, wherein the two hydraulic mechanisms are communicated with each other. The planetary gear speed increaser is provided with a rack pull rod. Each hydraulic branch comprises a hydraulic pump, a one-way valve, a pressure-limiting valve, a brake-triggering hydraulic solenoid valve, an accelerator-triggering hydraulic solenoid valve, an oil storage cylinder, a hydraulic cylinder and multiple hydraulic pipelines. The two sides of a cylinder body of each hydraulic cylinder are provided with an oil-pressure pipe oil inlet connector and an oil-pressure pipe oil returning connector respectively. A push rod is arranged inside the cylinder body of each hydraulic cylinder. The automobile hydraulic start / stop system has the advantages that by using the electric hydraulic and mechanical combined action, the energy recycling storage during the automobile braking deceleration process is achieved, recycled energy is converted and output during the start-up process of a vehicle, the energy use ratio is increased, and the complex and high-cost design in the prior art is avoided. The automobile hydraulic start / stop system has the advantages of being energy-conserving, efficient, suitable for mass production, applicable to the matched application of various vehicle models, and high in practicality.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of automobile machinery, and more specifically, relates to an automobile hydraulic start-stop system. [0003] 【Background technique】 [0004] The car start-stop system is a system that recovers and stores the mechanical kinetic energy of the car when braking and decelerating while the vehicle is running. [0005] Compared with the traditional engine drive, the car starting drive has low transmission efficiency and high fuel consumption. Therefore, in the existing electric vehicle and hybrid vehicle technology, the starting drive of the vehicle all uses the electric energy consumed by the motor to realize the drive. For energy recovery, traditional vehicles generally have no relevant design, while in electric vehicles or hybrid vehicles, the energy recovery device generally uses the working principle of the motor to convert mechanical energy into electrical energy of a battery or super capacitor for...
