Problems solved by technology

However, in order to achieve accurate detection results, the TCU controller must truly meet the conditions and sequence of imitating actual work. It is necessary to start from the key into the ON gear to step on the brake, ignition, idle speed, first gear, etc. The operation process of the car, this technical solution Because there is no clutch involved in the hardware part, and because the vehicle TCU controller has corresponding requirements for vehicle speed and throttle opening when shifting manually, that is to say, different gears correspond to different vehicle speeds and throttle openings, so , the detection result is not accurate enough

Embodiment Construction

[0021] The AMT transmission shifting test system of the present invention is mainly composed of two parts, one is the transmission shifting test device as the mechanical structure part in the action execution in the test, and the other is the control system that controls the entire system in the test .

[0022] Depend on figure 1 As shown in the figure, the transmission shift test device, which is the mechanical structure part of the action execution in the test, is connected and installed according to the actual vehicle conditions. Assembly 5, wherein the clutch assembly 2 further includes a release bearing 21 and a release fork 22, and the electric shifter assembly 5 includes a gear selection motor 51 and a gear shifting motor 52, and the entire mechanical structure is controlled by the TCU controller 6, During the test, the fixed speed of the motor 1 drives the clutch assembly 2 through the driving spindle 7, and the power of the AMT transmission 4 is interrupted and conne...

Abstract

The invention relates to a durability testing system of a speed changer, and particularly relates to a gear change testing system of an AMT (Automatic Mechanical Transmission) speed changer. The system comprises a speed changer gear-change testing device and a control system which are arranged and connected according to actual vehicle conditions, wherein the control system generates control signals according to the operation startup sequence of a TCU (Transmission Control Unit) controller (6), so that the TCU controller (6) has a working state capable of controlling the gear selecting of the speed changer gear-change testing device. By adopting the technical scheme, the speed changer gear-change testing device has the hardware arrangement which is identical to the structure in the actual vehicle use process, so that the speed changer gear-change testing device can completely simulate actual testing of the clutch operation, gear selecting operation, gear change operation and other links of the vehicle under the control of the control system, and the detecting result is accurate; and under the control of the control system, the speed changer gear-change testing device can simulate the gear increasing and gear decreasing operations between two gears through a manual gear by a driver, thus the testing purpose of repeated gear change is realized.

Description

technical field [0001] The invention relates to a transmission durability performance test system, in particular to an AMT transmission shift test system. Background technique [0002] With the continuous maturity and development of automatic control technology of mechanical transmission, an actuator that uses a DC motor as a power source and a simple deceleration transmission as an actuator to complete clutching, gear selection, and shifting actions is used in various on the car. As a more important component in the car, its durability and performance can not wait to be broken, and it is placed in front of people in a grand manner. For vehicle manufacturers, before using this device as an outsourced part, the manufacturer is always required to give a durability test report. The authenticity and credibility of the report cannot be achieved because they do not have the test equipment in this area. judge. Because the test load of the manufacturer is a gearbox without power ...
