Electromagnetic foot valve applied to efficient energy recovery system of new energy commercial vehicle

Abstract

An electromagnetic foot valve applied to an efficient energy recovery system of a new energy commercial vehicle comprises a connector, an upper valve body and a lower valve body, wherein the connector is installed above the upper valve body, an ejection rod seat, a balance valve and an upper cavity valve assembly are sequentially arranged inside a cavity formed by the connector, the upper valve body and the lower valve body, an air spring is arranged between the ejection rod seat and the balance valve, an air inlet pipe of the air spring is connected with an air source through an electric control pressure-regulation valve, an acceleration sensor is connected to the ejection rod seat, the ejection rod seat is provided with a top face, a potentiometer assembly is arranged on the connector and is provided with an ejection rod, the ejection rod abuts against the top face of the ejection rod seat, and electric signals of the potentiometer assembly are connected with the electric control pressure-regulation valve. The electromagnetic foot valve applied to the efficient energy recovery system of the new energy commercial vehicle improves recovered energy of the vehicle, enables a foot, treading the electromagnetic foot valve, of a driver to feel comfortable, guarantees that the driver has qualified braking force to perform matched braking whenever the vehicle runs at any speed and emergency braking is needed, and enables the vehicle to be stopped stably in the shortest time and distance.

Description

technical field [0001] The invention relates to an auto part, in particular to an electromagnetic foot valve of a braking energy recovery system for a new energy commercial vehicle. Background technique [0002] After entering the 21st century, while the world economy is growing at a high speed, it has also brought many environmental problems. Especially in recent years, the frequent occurrence of smog in our country has caused frequent occurrence of diseases related to the respiratory tract. Therefore, in the face of harsh environmental problems, the related industries that cause pollution need to reflect deeply. According to the statistics of experts, at least 10% of the main causes of smog are due to vehicle emissions, that is to say, solving the problem of vehicle emissions can contribute more than 10% to the "blue sky" that people expect. It is precisely for this reason that our country issued a series of very strong support policies for new energy vehicles during the...

AI Technical Summary

Problems solved by technology

Traditional electromagnetic foot valves use rubber springs and metal springs. Due to the increased idle travel of new energy vehicles, the entire braking process becomes very heavy.

In addition, when the driver brakes in an emergency, the pedal displacement of the electromagnetic foot valve will send a signal to the generator, which will affect driving safety.
