功能和结构概述本仪器用于测试公共汽车、电车、载重卡车、拖拉机以及其它各种机动车的制动、加速、滑行性能等,具有如下功能。(1)随时测定车辆的瞬时速度;(2)预置某个特定的车速,当达到预定车速时,发出制动信号(同时发出声响和灯光信号);(3)在规定车速下制动,以数字显示出制动以后车辆的滑行距离(称为刹车距离),(4)测定从脚踩刹车踏板开始至车辆减速到规定速度为止的时间间隔(称为刹车时间);(5)随时测定车辆的加速度;(6)测定车辆的滑行距离,即从某一规
Function and Structure Overview This tester is used to test the braking, accelerating and coasting performance of buses, trams, trucks, tractors and other vehicles. It has the following functions. (1) measuring the instantaneous speed of the vehicle at any time; (2) presetting a specific vehicle speed, issuing a braking signal (both audible and lighting signals) when a predetermined vehicle speed is reached; (3) braking at a prescribed vehicle speed, (4) Determine the time interval from the start of the pedaling of the brake pedal to the deceleration of the vehicle to the specified speed (referred to as the braking time); (5) Measurement of the vehicle’s coasting distance Vehicle acceleration; (6) Determination of the vehicle taxiing distance, that is, from a regulation
