Test is an important component of tire production quality control and quality guarantee system, can reflect the safety of tire construction
The integrated performance indexs such as performance.
During the test, tire will receive the test of the various limit, and wherein compulsory test just has size, intensity, durable, high
Speed, knocking over five detections, wherein tire knocking over performance is an important inspection project of tire quality, and tyre and rim holds very much
Easily skid, dislocation, if tire bead and wheel rim there is circumferential direction between conjunction face or slide axially, then can be to tire safe capability
Bring grave danger.So in order to solve to carry out knocking over performance test to finished tire, it can be to tire running using which kind of equipment
Process is effectively simulated, and is suitble to the knocking over performance testing device of industrial-scale production, is carried out to China's tire quality
Check on and then improve a major issue of tire quality.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, disclose a kind of novel tire bead unseating test device, institute
It adopts the technical scheme that:
A kind of novel tire bead unseating test device, including rack, dynamical system, transmission system, friction platform, the power
System is located at the bottom end of rack, and the friction platform connects dynamical system, and the friction plateau levels are arranged and are liftable knot
Structure, the transmission system are fixed on frame upper end and adjacent with the friction platform, and the transmission system includes cylinder, straight-tooth
Item, gear, bearing, shaft, flange, the spur rack is in vertical direction and connect with cylinder-driven, the gear and spur rack
By engaged transmission, the gear and shaft are connected with bearing, and the roller end is equipped with flange.
Further, the dynamical system includes hydraulic station and oil cylinder.
Further, the hydraulic station using 3KW stand-alone type hydraulic station and is equipped with point driving switch.
Further, the cylinder is equipped with point driving switch.
Further, the cylinder upper end is equipped with plunger, and the plunger can be gone up and down along the vertical direction, and the friction is flat
Platform is set to upper end and is to be detachably connected with plunger.
Compared with prior art, the utility model effectively simulates knocking over situation in tire traveling process, performance it is stable and
