Description
Technical field
Truck part field is the utility model is related to, is to be related to a kind of rubber bushing of balance shaft and balance specifically
Suspension assembly.
Background technology
In original art, truck balance shaft generally use metal bearing.Not only need to lubricate using metal bearing, easily
Cause oil leakage；And the rigid contact phenomenon of steel and steel being present, vehicle ride comfort is poor；There is also bearing itself weight simultaneously
Measure the problem of big.Has there is the rubber bushing for balance shaft in this area at present, primarily serves fixed, buffering, damping and stress
The effect of transmission, be advantageous to damping, fastness, security and the convenience of balance shaft.
In the patent document of Application No. 201420253566.0, it is " to be used for the balance of heavy truck to disclose theme
The scheme of axle rubber bushing ", plan content are：" it is used for the rubber bushing of balance shaft of heavy truck, there is metallic framework and elasticity
Body (1), elastomer (1) is equipped with the metallic framework inside and outside circle side face, it is characterised in that：The metallic framework is by tubbiness
Metallic framework (11), endless metal stiffener plate I (2), endless metal stiffener plate II (3) and endless metal stiffener plate
III (4) are formed, the endless metal stiffener plate I (2), endless metal stiffener plate II (3) and endless metal reinforcement
Plate III (4) is sleeved on tubbiness metallic framework (11) one end successively, and endless metal stiffener plate I (2), endless metal are strengthened
Gusset II (3) and the external diameter of endless metal stiffener plate III (4) are sequentially reduced.”
The documents disclose most technical characteristics, regard as immediate prior art.
The scheme that the prior art is provided, has the following disadvantages in actual applications：
1. because rubber stiffness is smaller, therefore rubber bushing needs prestressing force to increase rubber bushing rigidity, prevents rubber mistake
Fast creep；In scheme clear and definite " 3 ring stiffener plates are sleeved on barreled metallic framework one end successively ", in fact define in gold
Belong to skeleton longitudinal direction, ring stiffener plate can not exceed tubbiness metallic framework.Under such structure, ring stiffener plate is being held
During by longitudinal prestressing force, the contact surface stress point of rubber bushing and pressed component is right mainly in the side of tubbiness metallic framework
Discontinuity for whole contact surface, influences fixed effect；Simultaneously can be to the elasticity of parcel with the side of tubbiness metallic framework
Body produces larger shearing force, easily causes the breakage of rubber bushing.
2. the elastomer on skeleton inner peripheral surface is into a single integrated structure, elasticity is relied only on when contacting and fixing with balance shaft
The frictional force of body its own face, so as to cause frictional force relatively low；Also result between different parts and involve mutually simultaneously, if tubbiness
Metallic framework local deformation, not only the contact of deformation position and friction it is impacted, other positions also can because mutually involve and by
Influence.
Therefore, develop that a kind of fixed effect is more preferable, the rubber bushing of balance shaft of less cracky is people in the art
The task that member urgently completes.
The content of the invention
