Further, described pedestal is two stepwise pedestals, and described tapped hole connects pedestal.
Further, described end cap I, end cap II, Jin belong to sulfidization molding between Jia Qiang Zhu plate and elastomer.
The utility model advantage compared with prior art:
1, between end cap I and metal reinforcing plate and end cap II and metal reinforcing plate, be provided with elastomer, elastomer Compression and Expansion intensity is high, and rebound elasticity is good, and wear resistance, ageing resistance and damping, buffering performance significantly improve, and gearbox is improved working life greatly.
2, end cap I and end cap II adopt ductile iron material to make, make its withstand voltage and wear-resisting property raising, simultaneously snubber block is connected with vehicle frame with gearbox respectively by the step type pedestal at lid I and concave surface arc structure middle part in end cap II, can effectively absorb the vibrations that nut is subject to, connection part is located at and is covered I and end cap II is subject to impacting minimum position, effectively guarantee the integrity of union piece.
3, end cap I and end cap II are provided with arcuation projection and arcuation groove, and elastomer can guarantee elastomer and the reliability that end cap I is connected with end cap II after sulfidization molding, improves to greatest extent its tear-resistant performance.
4, metal reinforcing plate is located between end cap I and end cap II and on metal reinforcing plate and is shaped with center hole and circular hole, when sulfidization molding, elastomer can closely be connected by center hole and circular hole as a wholely, has improved firm degree and the comprehensive reducing shock stability of snubber block.
5, simple in structure, cheap for manufacturing cost, easy to use, improved vehicle safety simultaneously, reduced tare, reduced user's operation cost, reduced to a great extent after-sales service workload, improved lorry overall performance.
