Description
技术领域technical field
本发明属于汽车配件技术领域，具体涉及一种盘式制动器的摩擦块厚度专用量具。The invention belongs to the technical field of auto parts, and in particular relates to a special measuring tool for the thickness of a friction block of a disc brake.
背景技术Background technique
盘式制动器由于散热性好、使用中无需调整刹车片间隙及维护方便等优点，在汽车上广泛地采用。如图2所示，盘式制动器包括刹车片和刹车盘5，刹车片包括金属基底3和摩擦块4，金属基底3和刹车盘5分别设于摩擦块4的两侧。然而，盘式制动器刹车片上的摩擦块4在使用过程中会逐渐变薄，当摩擦块4磨损至极限时，制动力会下降而且刹车片上的金属基底3会与刹车盘5摩擦损坏刹车盘5，现在的汽车中除高档汽车所安装的刹车片中设有摩擦块磨损自动报警装置，大部分汽车在每次保养时需要人工检查摩擦块4的厚度，然而一般的维修工在检查时以目测为主，原因是不将刹车片从制动器上拆卸的情况下、利用现有的游标卡尺不方便精确测量摩擦块4的厚度，以目测方式虽然能够大致估计得到摩擦块4的厚度，但是估计值不准确，为了行车安全考虑、维修工一般会在摩擦块4的厚度实际未达到极限值时，提前让车主更换刹车片，这样一方面会使刹车片过早地被淘汰，增加车主的成本，另一方面也会由于维修工的误判而使得本应该更换的刹车片而未能及时更换。Disc brakes are widely used in automobiles because of their good heat dissipation, no need to adjust the brake pad clearance during use, and convenient maintenance. As shown in FIG. 2 , the disc brake includes a brake pad and a brake disc 5 , the brake pad includes a metal base 3 and a friction block 4 , and the metal base 3 and the brake disc 5 are respectively arranged on both sides of the friction block 4 . However, the friction block 4 on the disc brake pad will gradually become thinner during use, and when the friction block 4 wears to the limit, the braking force will drop and the metal base 3 on the brake pad will rub against the brake disc 5 and damage the brake disc 5, In current automobiles, the brake pads installed in high-end automobiles are equipped with automatic alarm devices for friction block wear. Most automobiles need to manually check the thickness of friction block 4 when maintaining each time. Mainly, the reason is that it is inconvenient to accurately measure the thickness of the friction block 4 by using the existing vernier caliper without removing the brake pads from the brake. Although the thickness of the friction block 4 can be roughly estimated by visual inspection, the estimated value is not accurate. For the sake of driving safety, maintenance workers generally ask the owner to replace the brake pads in advance when the thickness of the friction block 4 does not actually reach the limit value. On the one hand, the brake pads that should have been replaced will not be replaced in time due to the misjudgment of the maintenance worker.
发明内容Contents of the invention

The length of the ruler is less than the length of the ruler rod. The two ends of the ruler rod are respectively the pressing end and the reading end. There is a pressure head fixed on the outer circular surface of the ruler sleeve near the pressure end. The pressure head is located in the radial direction of the ruler sleeve. The pressure head is close to the pressure head. The bottom wall near the end is flush with the end face of the ruler sleeve; the reading end is provided with a scale on the axial direction of the ruler rod, and the sum of the length difference between the ruler rod and the ruler sleeve and the thickness of the indenter on the axial direction of the ruler sleeve is equal to the range of the scale.
在使用本发明的量具时，先将量具上靠近压头的一端穿过车轮轮圈上的通孔、伸入到制动器的一侧，在伸入过程中，如果压头遇到无法躲避的障碍则可以旋转尺套，使压头转到另一方向上，从而躲避障碍。然后，将尺杆的压靠端平整地压靠在制动盘的侧面上，尺套使压头伸入到摩擦块的侧面，压头的端部抵靠在摩擦块的侧壁上，向外移动尺套使压头的顶壁压靠在刹车片的金属基底的下侧壁上，此时从尺杆的刻度上读取露出的刻度值，若0度线远离读数端的端面时，以压头的顶壁与尺杆的下端壁平齐时的刻度值作为0度线，则读取的刻度值即为被测量的摩擦块厚度。若0度线靠近读数端的端面时，同上测量之后，再将量具取出后将压头的顶壁与尺杆的下侧壁平齐，从尺杆的刻度上读取露出的刻度值，将两次计数相减之后取绝对值则可得到被测量的刹车片的摩擦块厚度。When using the measuring tool of the present invention, first pass the end of the measuring tool close to the indenter through the through hole on the rim of the wheel and extend to one side of the brake. Then the ruler cover can be rotated to make the indenter turn to another direction, thereby avoiding obstacles.

At this time, read the exposed scale value from the scale of the ruler rod. If the 0 degree line is far away from the end surface of the reading end, use The scale value when the top wall of the indenter is flush with the lower end wall of the ruler rod is taken as the 0 degree line, and the read scale value is the thickness of the friction block to be measured. If the 0 degree line is close to the end face of the reading end, after the same measurement as above, take out the measuring tool and make the top wall of the indenter flush with the lower side wall of the ruler rod, read the exposed scale value from the scale of the ruler rod, and place the two The thickness of the friction block of the measured brake pad can be obtained by taking the absolute value after subtracting the counts.
