Abstract

The invention relates to a method for performing a clutch transmission efficiency test on a vehicle. The method for performing the clutch transmission efficiency test on the vehicle comprises the steps that a test system hardware is connected; vehicle warm-up is carried out; when the tested vehicle is fully loaded, a tester puts a transmission into a first or second gear, an actual vehicle road initial starting test is carried out according to the habit of the tester, an accelerator pedal is not stepped in the test process, and when the vehicle speed is not lower than the lowest stable vehiclespeed of the gear, the test is stopped; and the vehicle clutch transmission efficiency is determined by the road taxiing resistance, the acceleration resistance, the wheel edge received power, the engine output power and the vehicle clutch efficiency. According to the technical scheme, the vehicle clutch transmission efficiency test is carried out on an actual road, and the advantages of convenient operation, high repeatability and reliable test are achieved.

Description

technical field [0001] The invention belongs to the technical field of clutch performance testing, in particular to a method for testing clutch transmission efficiency on a complete vehicle. Background technique [0002] The clutch is a component directly connected to the engine in the car transmission system, and it takes on the role of disconnecting and combining the power system and the transmission system, so it can ensure a smooth start when the car starts, and it can also ensure smooth shifting and prevent transmission The system is overloaded. Higher clutch efficiency can better achieve fuel economy, and the level of clutch efficiency can comprehensively reflect its performance, such as design level, manufacturing process and related parts installation and matching accuracy and other issues. [0003] At present, most of the clutch transmission efficiency tests install and arrange the clutch operating system on the operating platform according to the actual vehicle me...
