摘要
The meter for measuring wheel (4) spoke (5) tension functions automatically with force applied squarely on the length of the spoke and the extent of bending measured. Force is then applied in the opposite direction and the average of both measurements is used to determine the spoke tension. The meter (1) has a housing (15) with a large opening in the front side. In the housing on the under side is a height-adjustable support stirrup (8) with a support roller (7). On the upper side is a clamp stirrup (2) with two clamp rollers (3) in the housing. The clamp stirrup is adjustable in its height by means of a knob. By raising the clamp stirrup a wheel can be placed between the support roller and the clamp rollers. In the housing by means of a ball hinge, a pivot arm (9) is fitted, which is movable by a pneumatic cylinder (6) of which the stroke can be adjusted. On the pivot arm is a measurement head (10). The height of the support stirrup is then so adjusted that the measurement head can engage at the required height on the spoke.
