Further, wheel is additionally provided with oil filler point in the heart.
Further, being evenly arranged with pressure ring on the screw of more than six, the correspondence position of core wheel has identical quantity
Screw, pressure ring is fixedly connected with core wheel by fastener.
The beneficial effects of the utility model are：
1. the angle of " V " the type hypotenuse and horizontal direction between two rubber ring cross-sections of the utility model is 13-17o, i.e., it is same
When meet requirement in terms of wheel stiffnesses and elasticity, can guarantee that again axletree consolidating upwards, avoid between core wheel and rim because
Slide and derail, moreover it is possible to which " V " type bottom stress excessively influences rubber ring when making that rubber ring stress is more uniform, avoiding angle too big
Service life.
2. the decrement of rubber is 0.5-1mm in the utility model rubber ring, the type variable of thickness direction is 3.5-4.0%,
Rubber ring is not produced fold after being squeezed, extend the service life of rubber, reduce the replacing number of times of rubber ring, reduction
Maintenance cost.
