Research method of hump overload vehicle reducer

Abstract

The invention discloses a research method of hump overload vehicle reducer. The method comprises the following steps: first step: the overload vehicle reducer is developed; the second step: the choice range of crank throw eccentric distance is ascertained according to the calculation and analysis of the relationship between crank throw eccentric distance and transmission pressure; the third step: through stress analysis and calculation and combining with fatigue test and finite element analysis, the structure of key part is ascertained, mechanical strength requirement under the condition of overload is met; the fourth step: the brake locking that the reducer acts on overload vehicles is achieved, and the key technology of remitting deblocking is achieved. The research method of hump overload vehicle reducer has the advantages of being suitable for overload vehicles, wide in the range of application, convenient to maintenance and repair, and capable of directly tearing down rail bearing and changing the stressed members of broad concrete tie under the condition of blocking paths, being convenient to daily maintain and repair, reducing the influence for transportation.

Description

technical field [0001] The invention relates to a research method of a speed reducer, in particular to a research method of a hump heavy-duty vehicle speed reducer, and belongs to the technical field of speed reduction products. Background technique [0002] The hump vehicle reducer control system is generally composed of a correction link (computer), an execution link (reducer), a controlled object (vehicle group) and a feedback link (speed radar). The correction link is a digital proportional-derivative (PD ) controller, but due to the uncertainty of the parameters of the controlled vehicle group and the long delay in the action of the reducer, and the control process is easily affected by changes in weather and slope, especially at interval braking positions where the vehicle speed is high and the slope is large, the vehicle The motion stability is poor, and conventional PD control alone cannot achieve ideal results. For the interval braking position using T1K pneumatic n...

[0002] The hump vehicle reducer control system is generally composed of a correction link (computer), an execution link (reducer), a controlled object (vehicle group) and a feedback link (speed radar). The correction link is a digital proportional-derivative (PD ) controller, but due to the uncertainty of the parameters of the controlled vehicle group and the long delay in the action of the reducer, and the control process is easily affected by changes in weather and slope, especially at interval braking positions where the vehicle speed is high and the slope is large, the vehicle The motion stability is poor, and the simple use of conventional PD control often cannot achieve ideal results. For the interval braking position using T1K pneumatic non-gravity reducer, it has always been difficult to improve the control accuracy of the reducer by using conventional control strategies. Some automatic hump interval braking Bit control accuracy has greatly restricted the improvement of peak pushing speed
