Double-row pressurized volumetric type lubricating medium quantitative distributor

Abstract

A double-row pressurized volumetric type lubricating medium quantitative distributor relates to the technical field of lubrication systems, and solves the technical problem of shortening the unloading time. The distributor includes a main pipeline and a plurality of quantitative valves, wherein at least two main pipeline mounting pieces are fixedly arranged on a pipe wall on one side of the main pipeline at intervals along the axis of the main pipeline; and the distributor is characterized in that a plurality of quantitative valve mounting pieces ranged in two rows and multiple columns along the axis of the main pipeline are arranged on a pipe wall on one side of the main pipeline; each quantitative valve mounting piece is provided with a quantitative valve mounting hole; and further, all the quantitative valves are mounted respectively in the quantitative valve mounting holes in the quantitative valve mounting pieces, a distribution through hole communicated with a pipe cavity of the maim pipeline is formed in the bottom of each quantitative valve mounting hole, and the apertures of the distribution through holes are smaller than the apertures of the quantitative valve mounting holes and the inner diameter of the main pipeline. The distributor provided by the utility model has short unloading time and is convenient to mount.

Description

technical field [0001] The invention relates to lubrication system technology, in particular to the technology of a double-row pressurized volumetric lubricating medium quantitative distributor. Background technique [0002] The centralized lubrication system for automobile chassis is a new technology designed to meet and guarantee the daily maintenance of vehicles. It is a fully automatic (timing, quantitative) mandatory lubrication system suitable for various passenger cars and trucks. [0003] The quantitative distributor of lubricating medium is the core component of the lubrication system of the automobile chassis. The quantitative distributor of lubricating medium is mainly composed of the main pipeline connected to the lubricating pump and multiple quantitative valves installed on the main pipeline. Each friction pair of the car ensures the smooth operation of the mechanical mechanism of the car chassis. [0004] The existing lubricating medium quantitative distribut...

AI Technical Summary

Problems solved by technology

[0004] The existing lubricating medium quantitative distributors all adopt a single-row quantitative valve structure, that is, each quantitative valve is arranged in a single row on the main pipeline along the pipeline, resulting in a longer length of the main pipeline required for the unit load, so that the existing lubricating medium is quantitatively distributed. The unloading time of the device is also longer, which reduces the sensitivity and oil output accuracy of the lubrication system, and the length of the main pipe required for the unit load is longer, which is not conducive to the installation of the lubricating medium quantitative distributor, such as the front of the car chassis. Both the axle lubrication distribution group and the rear axle lubrication distribution group need to use multiple lubricating medium quantitative distributors in series, resulting in a long overall length of each distribution group. Due to the space limitation of the vehicle chassis, the front and rear axle lubrication distribution groups need to extend to the vehicle chassis Side girders, arrange main pipes along the direction of the girders
