Abstract

The invention discloses a heavy-duty car gearbox detection device, and relates to the technical field of mechanical industry. The heavy-duty car gearbox detection device comprises a power source, a 1# torquemeter, a gearbox to be tested, a 2 # torquemeter, a speed increasing box, an eddy current dynamometer, an electric hydraulic pump and a gearbox gear shifting control handle. The power source is connected with the 1 # torquemeter, the 1 # torquemeter is connected with the gearbox to be tested, the gearbox to be tested is connected with the 2 # torquemeter, the 2 # torquemeter is connected with the speed increasing box, and the speed increasing box is connected with the eddy current dynamometer. According to the heavy-duty automobile gearbox detection device, the speed increasing box isadditionally arranged between the gearbox and the eddy current dynamometer, and the rotating speed is increased to 1000r / min when the rotating speed of the gearbox is low, so that the eddy current dynamometer absorbs power, and the application range of the eddy current dynamometer to the rotating speed of the gearbox is enlarged.

Description

technical field [0001] The invention relates to the technical field of machinery industry, in particular to a heavy-duty vehicle transmission detection device. Background technique [0002] At present, there are few existing technologies for automobile gearbox testing in China, and the eddy current dynamometer in the existing technology has certain requirements for the input speed when it is working normally, the minimum must be 1000r / min or above, and the tested variable speed Especially in the low gear and reverse gear test, its output speed is only more than 300 revolutions. At this speed, the eddy current dynamometer cannot perform power absorption, and it cannot be tested normally. So far, there are two solutions. Solution 1: Customize a larger eddy current dynamometer to meet the dynamometer requirements at low speed and high torque. Revert to high revs to meet the input demands of the dyno. [0003] Option 1 Manufacturing such an eddy current dynamometer is not only...
