Technical Field

The invention relates to the technical field of spoked wheels, in particular to a spoke cap and a spoked wheel.

Background

In motorcycles and bicycles, spoked wheels are often used. The spoked wheel mainly comprises a hub, a rim and spokes for connecting the hub and the rim, and the spoked wheel can absorb impact and can also realize light weight through deformation of the rim and the spokes, and can be automatically adjusted if an obstacle is met.

Vacuum tires are widely used because of their low puncture performance, however, in the prior art, the spoked wheel for vacuum tires on the market is provided with mounting holes directly formed on the rim, and then the spokes are sealed and mounted by spoke caps to achieve tubeless design. Chinese patent application No. 201780040843.6 discloses a joint for tubeless spoked wheels comprising first and second shoulders formed on a stem having an axial blind bore with an internal thread at one end of the stem, the first shoulder being at the distal end of the opening of the axial bore and the second shoulder being in the region of the stem near the opening. A first recess for a seal ring is formed on the stem, the first recess being rearward of the first shoulder, and at least one second recess for a second seal ring is formed on the stem between the first recess and the second shoulder. Although the spoke cap with the structure can meet the sealing requirement, the requirement on the machining precision is high, if the fit clearance between the sealing ring and the concave part is too large, the sealing performance of the spoke cap is difficult to meet the requirement, and if the fit clearance between the sealing ring and the concave part is too small, the sealing ring is easy to damage after being extruded, so that the service life is greatly reduced, and therefore the problem is urgently needed to be solved.
