Drag characteristic prediction system of wet brakes wi th heavy-duty and of f-road
摘要
Abstract
The wet multiple of disc brake (WMDB) in mining engineering truck′s drive axle was stud-ied to enhance the characteristics of WMDB .A prediction system specific to the drag characteristics phenomenon during in wet brake non-engagement was established ,considering the surface grooves effect ,film shrinkage and laminar N-S equations as factors .The prediction system was built up to un-derstand drag torque and temperature′s variation of wet brake at different volume flow ,dynamic vis-cosity and friction pair clearance .The results indicated that when the friction pair gap is under varia-ble circumstance ,the larger friction pair gap of predictive models feature ,the lower peak torque ;when the volume is variable ,the peak torque rises with an increasing volume flow of torque prediction model ;w hen the cooling liquid viscosity is dynamic ,the peak torque increases as the torque prediction model coolant dynamic viscosity is greater .关键词
