Abstract

Provided are a hybrid environmental sanitation vehicle ATM speed changing box power takeoff device and a control method thereof. The device comprises a power takeoff, a driving motor, a power takeoffelectromagnetic valve power supply switch (7) , a power takeoff electromagnetic valve (8) and a whole vehicle controller. The driving motor is arranged between a clutch and a speed changing box, a driving motor output shaft is connected with a speed changing box input shaft (1), a power takeoff input shaft (4) is connected with a speed changing box intermediate shaft (3), a power takeoff driving air cylinder (6) is connected with a power takeoff shift fork (9), the power takeoff electromagnetic valve (7) is connected with the power takeoff electromagnetic valve (8), and the power takeoff electromagnetic valve (8) is respectively connected with the power takeoff driving air cylinder (6) and an air cylinder (10) of an environmental sanitation vehicle; the method includes the following stepsthat a clutch is separated, the power takeoff electromagnetic valve (8) is started, it is judged whether the vehicle is successfully in gear or not, and the gear engaging is finished. The abrasion ofthe clutch is reduced, and the service life of the power takeoff is prolonged.

Description

technical field [0001] The present invention relates to a power take-off device and a control method thereof, and more specifically relates to a power take-off device of a hybrid sanitation vehicle AMT gearbox and a control method thereof. Background technique [0002] The energy-saving and low-emission characteristics of hybrid vehicles have become one of the important ways to alleviate the current energy crisis and environmental pollution. Therefore, in recent years, hybrid urban sanitation vehicles have made great progress in the field of urban sanitation operations. [0003] At present, the traditional PTO control method of automobile transmission cannot judge whether the PTO is in gear successfully, mainly through the driver's control of the clutch and the power supply switch of the PTO solenoid valve, and tentatively engaging the clutch to judge whether the PTO is in gear successfully; The control method is easy to cause problems such as gear hitting, clutch wear, engi...
