6.3.2 制动器操纵机构的调整
Adjustment of brake control gear
制动器的调整见图。
Adjustment of brake control gear refers to the figure.
通过调整限位螺钉 ll，使踏板中心与地板间的
高度为 175mm～185mm：通过调整限位螺钉
3，保证限位螺钉 3 与制动泵之间的间隙 A 为
3mm～ 4mm， 使踏板自由行程在 20mm～
26mm 范围内；工作行程为 110mm-120mm 范
围内。手制动操纵把手的工作行程为
220mm-250mm，调整手制动拉杆的长度，保
证在规定的工作行程范围内可靠地实现驻车
制动。具体调整方法为：将手制动操纵把手
置于初始位置（操纵杆水平放置)，取下开口
销，抽出销轴 7，松开螺母 9，转动拉杆叉 8
来调整手制动拉杆的有效长度，直到工作行
程满足要求为止。
Adjust the height between the center of the
pedal and the floor to(175~185)mm by
adjusting the limit screwⅡ；ensure that the gap
between the limit screw 3 and the brake pump
is (3-4)mm so that the free stroke of the pedal is
within (20~26)mm and the working trip is
within (110 - 120) mrn by adjusting the limit
screw 3. The working stroke of the manual
brake control handle is (220 - 250) mm. Adjust
the length of handbrake rod to ensure reliable
parking and brake in the scope of the regulated
working stroke. The specific adjust methods
are: put the manual brake control handle at the

重要事项：
IMPORTANT:
应经常检查及调整离合器自由行程，确保踏板自由行程在 30mm～40mm。
The free stroke of the clutch should be often checked to ensure that the free stroke of the pedal is (28～
40) mm so to prevent abnormal clutch wear.
