Centralized lubricating method and chassis centralized lubricating system

Abstract

The invention discloses a centralized lubrication method and a chassis centralized lubrication system, and belongs to the technical field of automobiles. The centralized lubrication method comprises the steps that after an ignition switch of a vehicle is started, a wheel speed sensor located at the position of a hub detects whether the vehicle is in a running state or not; when the vehicle enters a running state, the ignition switch and the wheel speed sensor send signals to the lubrication control module at the same time, and the lubrication control module starts timing of a first preset lubrication period; and when a first preset lubricating period is reached, the lubricating control module starts the lubricating pump, the lubricating grease is distributed to the sub-path grease distributor through the main path grease distributor according to the preset flow, and the sub-path grease distributor injects the lubricating grease into lubricating points of the vehicle. Two reference factors of an ignition switch and a wheel speed sensor are adopted, and a single timing mode of an automobile ignition switch is changed; and the main path grease distributor and the sub-path grease distributor are adopted for regularly and quantitatively filling lubricating grease to vehicle lubricating points, so that the vehicle maintenance period is prolonged, and the maintenance difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a centralized lubrication method and a centralized lubrication system for chassis. Background technique [0002] A refrigerated truck is a closed van transport vehicle used to maintain the temperature of frozen or fresh goods. At present, the lubrication points of the refrigerated truck chassis are maintained by manual regular pressure injection of grease, which has the disadvantages of long maintenance time, difficulty in checking the lubrication status, and easy to add too much or too little grease and cause waste of grease. [0003] Especially after the upper tank of the refrigerated truck is installed, the lubricating points are under the tank, which makes the operation more difficult when adding grease, and the maintenance time and cost become larger. [0004] For this reason, it is urgent to provide a centralized lubrication method and a centralized lubrication system ...
