The invention discloses a lubrication control method for rear axle braking of a high-horsepower HMCVT tractor, and belongs to the field of lubrication control. According to the lubrication control method, when a brake pedal is loosened or a vehicle speed after direct braking is smaller than or equal to the minimum limit speed of brake lubrication after a brake lubrication command is sent out; at the moment, the acting time of an lubricating oil on a hydraulic disc brake cannot be guaranteed, so that the cooling effect cannot be achieved, command delay is carried out by introducing a current delay time, a lubricating channel is continuously conducted, and the lubricating oil is adopted to continuously cool and lubricate the hydraulic disc brake during the period until the delay time is ended; in the vehicle braking process, the process is repeated, the lubricating and cooling effects of the hydraulic disc brake can be guaranteed, and lubricating oil is not wasted.
本发明公开了一种大马力HMCVT拖拉机后桥制动的润滑控制方法,属于润滑控制领域。本发明的大马力HMCVT拖拉机后桥制动的润滑控制方法,在制动润滑命令发出后出现松开制动踏板或直接制动后的车速小于等于制动润滑最小限制速度的情况时,此时,润滑油对液动片式制动器的作用时间不能保证,从而并不一定能达到冷却效果,通过引进当下的延迟时间进行命令延迟,润滑通道继续导通,润滑油在此期间继续对液动片式制动器继续进行冷却润滑,直至延迟时间结束;在车辆制动过程中,重复上述过程,能够保证液动片式制动器的润滑冷却效果,且不浪费润滑油。
