驻车制动力的检验方法分析

Analysis on Inspection Methods of Parking Brake Force

根据全国农用运输车统检的统计资料，以及车辆在上、下坡路面上驻车状态的受力分析，认为反力式制动试验台只具有单向拖动能力（即只能模拟下坡驻车状态），当以反力式制动试验台进行出厂检验和安全性能检测时，造成相反方向（即上坡驻车状态）驻车制动性能的全面漏检。

According to the countrywide statistical data of the unified inspection on agricultural used automobiles and the analysis of vehicle parking forces in the state on upward slope and downward slope road surface,consider that the counterforce type testing stand has only the capability of singledirection towing force (i.e.merely can simulate the vehicle parking state on downward slope).Thus when the counterforce type brake testing stand is used for inspecting and measuring safety performance of manufactures delivered vehicles,the parking brake performance of oppositedirrection (parking state on upward slope)is missed out in inspecting.
