Seal 103, the outside of sealing ring 103 crimps mutually with the inwall of big footpath groove.This balanced suspension for heavy-duty vehicle sealing device makes
Have the disadvantage that during with when the wear extent of lining is more than the radial compensation amount of sealing ring under bad working environments, will go out
The problem of existing equalizing type of suspension leakage of oil, affects the serviceability of equalizing type of suspension.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of balanced suspension for heavy-duty vehicle sealing device, to solve
When the wear extent of lining is more than the radial compensation amount of sealing ring, the problem arising that equalizing type of suspension leakage of oil.
In order to solve the problems referred to above, the technical solution adopted in the utility model is: this balanced suspension for heavy-duty vehicle seals
Device, includes the balance suspension support and spring perch being sleeved on gimbal axis, in described spring perch and institute
Stating equipped with lining between gimbal axis, the end of described balance suspension support is provided with seal groove, and described spring perch is provided with
Stretching into the round platform of described seal groove, described seal groove built with being fixed on the axial sealing ring of bottom land by alignment pin, described
The end face of the nearly described spring perch of axial sealing ring is equipped with felt, and other end is equipped with O.
In above-mentioned balanced suspension for heavy-duty vehicle sealing device technical scheme, more specifically technical scheme is it may also is that described
Axial sealing ring includes the first skeleton and the second skeleton, equipped with multiple bullets between described first skeleton and described second skeleton
Spring, described first skeleton and described second skeleton are connected by rubber ring sulfuration.
Further, the inner of described first skeleton is provided with multiple boss, and described second skeleton is provided with and described boss pair
The groove answered.
Further, described first skeleton and described second skeleton are equipped with multiple spring retainer pin.
Owing to have employed technique scheme, this utility model compared with prior art has the advantages that
1, this utility model is provided with seal groove in the end of balance suspension support, and spring perch is provided with and stretches into seal groove
Round platform, seal groove built with being fixed on the axial sealing ring of bottom land by alignment pin, at the nearly spring perch of axial sealing ring
End face is equipped with felt, and other end is equipped with O；At the effect lower steel plate spring base of pretightning force F by axial sealing ring to balance
Suspension strut compresses, and by felt seal between end face and the spring perch of axial sealing ring, other end is outstanding with balance
Being sealed by O between frame support, the sealing of axial sealing ring is not affected by the wear extent of lining, even if in severe work
When under condition, the wear extent of lining is bigger, axial sealing ring still ensures that its sealing property, it is to avoid equalizing type of suspension leakage of oil occur, it is ensured that
The serviceability of equalizing type of suspension.
2, axial sealing ring includes the first skeleton and the second skeleton, equipped with multiple bullets between the first skeleton and the second skeleton
Spring, the first skeleton and the second skeleton are connected by rubber ring sulfuration；Under the effect of multiple springs, the first skeleton and the second skeleton
Respectively O and felt are compressed, improve the sealing property of axial sealing ring further.
3, the inner of the first skeleton is provided with multiple boss, and the second skeleton is provided with the groove corresponding with boss；Prevent the first bone
Frame and the second skeleton relatively rotate.First skeleton and the second skeleton are equipped with multiple spring retainer pin, it is to avoid spring produces skew.
