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

【Technical field】 [0001] The invention relates to the technical field of automobile machinery, and more particularly, to an automobile hydraulic start-stop system. 【Background technique】 [0002] The car start-stop system is a system that recovers and stores the mechanical kinetic energy of the car when the vehicle brakes and decelerates during driving. When the vehicle needs to continue to move forward, the original stored energy is released to do work to propel the vehicle to start. [0003] Car start-up drive For traditional engine drive, the transmission efficiency is low and the fuel consumption is high. Therefore, in the existing electric vehicle and hybrid vehicle technology, the starting drive of the vehicle is realized by using the electric energy of the motor to consume the battery. For energy recovery, traditional vehicles generally do not have relevant designs, while in electric vehicles or hybrid vehicles, the energy recovery device generally converts mechanica...
