A bus brake energy recovery device

Abstract

Disclosed is a bus braking stop energy recovery device. On a road of an area where a bus stops, two rectangular pits are arranged according to wheel base of the bus, a hydraulic power generator, an ECU (electronic control unit), a storage battery, multiple water tanks, a water pipe and the like are arranged in each pit, a piston is arranged in each water tank, each piston rod penetrates through the top of the corresponding water tank in a vertical upwards manner, and top ends of the water tanks are connected with road pressure discs which vertically move up and down along with the pistons. The device has two states including a standby state and a working state, in the standby state, along the traveling direction of the bus, the first pressure disc is positioned at an ascending high position, other pressure discs are positioned at descending low positions; and in the working state, along the traveling direction of the bus, the pressure disc that the bus is about to press is positioned at the ascending high position, and other pressure discs are positioned at the descending low positions. The bus braking stop energy recovery device can effectively assist a vehicle in speed reduction at a stop area to enable the vehicle to be stable in speed reduction so as to reduce vibratory sensation and guarantee riding comfortableness; and by the bus braking stop energy recovery device, kinetic energy of the bus can be effectively converted into electric energy, so that energy conservation and environment protection are realized.

Description

technical field [0001] The invention relates to the field of public transportation, in particular to the stopping and stopping of buses. Background technique [0002] A bus refers to a motor vehicle that follows a fixed route on an urban road, with or without a fixed shift time, and carries passengers. It is generally rectangular in shape, and the number of carriages varies from 1 to 3. A bus stop area will be set at an appropriate distance to facilitate passengers to get on and off the bus. Buses are the most common form of public transportation. [0003] When the bus is in the parking area, the driver generally relaxes the gas pedal, and the brake pedal is stepped on to realize the stop brake through the stop brake pad. Due to the complicated vehicle conditions on urban roads, when parking, the driver often does not have enough time to fully slow down and stop the brakes. The brakes are usually relatively urgent, and passengers are often unable to stand firmly in the com...

AI Technical Summary

Problems solved by technology

Due to the complicated vehicle conditions on urban roads, when parking, the driver often does not have enough time to fully slow down and stop the brakes. The brakes are usually relatively urgent, and passengers are often unable to stand firmly in the compartment due to high inertia, and may even be injured; Simultaneously, rapid braking also causes relatively great damage to the braking components of the vehicle, and greater noise will be generated during braking; in addition, due to the large weight and load of the bus, the kinetic energy of the bus at the time of braking is quite large. , However, the current braking method does not recycle this part of energy well, resulting in a lot of energy waste
