Embodiment Construction

[0008] The structural principles of the present invention will be further described below through specific embodiments (see accompanying drawings).

[0009] The starter automatic test controller for vehicles has a starter, an oil supply solenoid, two DC power supplies, two intermediate relays, four time relays, a counting relay and a power switch. The head end of the first group of normally open auxiliary contacts of No. 1 intermediate relay J1 is connected to the positive pole of No. 1 DC power supply 3; the end of the first group of normally open auxiliary contacts of No. 1 intermediate relay J1 is connected to the starter 1 coil. The two ends of the second group of normally open auxiliary contacts of the No. 1 intermediate relay J1 are connected with the JS contacts of the counting relay (the order of arrangement of the relay auxiliary contacts is from bottom to top in the figure). No. 2 intermediate relay J2 is connected in series with No. 2 DC power supply 4 and fuel supp...

Abstract

The invention discloses an automatic test controller of a starter for a vehicle, which is characterized in that: based on circuit design, both ends of a normally open contact of an intermediate relay are respectively connected with a DC power supply and a starter coil, and an other normally open contact is connected with a counter; an other relay is connected in series with the DC power supply of a motor to control an oil supply electromagnet; a power switch is connected in parallel with a counting relay, and the counting relay is connected in parallel with four time relays; a second auxiliary contact of a No. 1 intermediate relay is connected in parallel between two of the time relays, a first auxiliary contact, a second auxiliary contact and a third auxiliary contact of a No. 2 relay are connected in parallel between the No. 2 time relay and the No. 3 time relay, and a normally closed contact of the No. 4 time relay is connected with the power switch. The invention can accurately control the attraction of the oil supply electromagnet of the motor, thereby realizing the oil supply and the oil interruption of the motor within specified time; in addition, the invention entirely completes the circular test experiment of the starter in an automatic state without manual intervention, also records the test results in real time, and has simple structure, low cost and high practicality.

Description

technical field [0001] The invention belongs to internal combustion engine components, in particular to a device for automatically testing the reliability of a vehicle starter. Background technique [0002] At present, the domestic and foreign automobile industry has higher and higher standardization requirements for various products involved. The main purpose is to improve the quality control of products. The starter is the main part of the car engine, and it should be checked whether the engine is supplied and cut off within the specified time. Carry out assessment, identification and screening in terms of quality, and realize the matching in the factory. But regrettably still do not have at present the special-purpose device that starter machine is supplied, oil cut-off reliability is carried out automatic test. In order to ensure the production quality of the engine, it is very important to automatically test and control the reliability of the starter. The establishme...
