Description

Изобретение относитс к испытательной технике, а именно к стендам дл испытаний гусеничных движителей.The invention relates to testing equipment, namely, stands for testing tracked propulsive devices.

Цель изобретени - расширение спектра нагружени элементов гусеничного движител по величине и частоте.The purpose of the invention is the expansion of the loading spectrum of the elements of a crawler mover in magnitude and frequency.

На фиг. 1 показан стенд, вид спереди; на фиг.2 - принципиальна кинематическа схема стенда.FIG. 1 shows a stand, front view; Fig. 2 shows the basic kinematic scheme of the stand.

Стенд состоит из основани 1 с закрепленной на нем рамой 2, на которой установлены ведущие мосты 3 и 4, гусенична лента 5, балансиры 6 с опорными катками 7. Ведущие мосты 3 и 4 соединены между собой силовым контуром, включающим соединительные муфты 8, карданные валы 9, привод 10, тормозное устройство 11 и нагружающее устройство 12 и гусеничные ленты 5. Ролики 13с приводом 14 позвол ют в процессе испытани имитировать рельеф местности .The stand consists of a base 1 with a frame 2 fixed on it, on which drive bridges 3 and 4 are mounted, track 5, balance weights 6 with support rollers 7. Drive bridges 3 and 4 are interconnected by a power circuit including coupling sleeves 8, cardan shafts 9, the actuator 10, the braking device 11 and the loading device 12 and the track belts 5. The rollers 13c by the actuator 14 allow to simulate the terrain during the test.

Стенд работает следующим образом.The stand works as follows.

Claims

The braking device 11 is activated, then with the help of the loading device 12 a load is created corresponding to the specified mode of this test phase, then the elastic coupling 15 is connected and the brake is released from the engagement. In a closed loop, a given load is circulated, proportional to the expended parasitic power. Drive 10 drives the entire circuit. The loading frequency (rotation speed) is varied by electronically controlling the DC motor (2PN200 PG 4.30 kW). When testing to create loads that imitate road conditions, rollers 13 are installed, the pressing force of which is regulated by a hydraulic actuator. Non-automatic regulation according to a program designed in accordance with the actual road conditions. Claims for testing a track mechanism of a tracked vehicle, comprising a frame with a tracked contour including a track, driving wheels and
