Clutch overload protection method

Abstract

The invention relates to a clutch overload protection device and method, in particular to a device and method used for preventing overload impact of a transmission clutch. The clutch overload protection device and method can avoid overload of the clutch caused by misoperation of a driver, so that the service life of the clutch is prolonged. The clutch overload protection device comprises a neutral gear signal switch (1) and a clutch position switch (6), wherein the neutral gear signal switch is installed on a gear shifting mechanism; the clutch position switch is installed inside the clutch; the two switches transmit signals of the two switches to an electronic control unit; the electronic control units controls an execution air cylinder to act through an overload protection electromagnetic gas valve. The clutch overload protection method comprises the following steps that the neutral gear signal switch (1) and the clutch position switch (6) are additionally arranged; the electronic control unit processes the signals, collected by a sensor, of the two switches; and the electronic control units controls the execution air cylinder through the overload protection electromagnetic gas valve.

Description

technical field [0001] The invention relates to the field of vehicle chassis, in particular to a device and method for preventing overload impact of a gearbox clutch. Background technique [0002] In the super heavy-duty manual transmission chassis, if the driver steps on the clutch pedal and the engine accelerator pedal at the same time when starting or changing gears, the difference between the engine speed and the clutch friction plate speed will increase, which will have a great impact on the clutch , leading to early wear or even ablation of the friction plate, affecting the service life of the clutch. However, in the actual use process, drivers often make misoperations. Simply relying on improving the clutch design safety factor and strengthening the training of drivers cannot prevent the occurrence of such failures. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a clutch overload protection device and me...
