Description
Technical field
The utility model relates to automobile suspended system field, relates in particular to a kind of automobile Anti-torque pull rod.
Background technology
Anti-torque pull rod is the strength member that connects dynamic assembly and subframe, as shown in Figure 1, traditional Anti-torque pull rod generally includes the support at metal pipe link 11 and pipe link 11 two ends, in the support at two ends, is provided with lining, one end is Large lining 14, and the other end is little lining 15.Large lining and little lining are fixed together by inner tube, outer tube, rubber bodies sulfuration, and the inner tube of little lining 15 is connected with dynamic assembly, and the inner tube of Large lining 14 is connected with subframe.Like this, the motion of the controlled braking force assembly of Anti-torque pull rod reduces the vibration of dynamic assembly to the transmission of subframe simultaneously, improves car load NVH(Noise noise, Vibration vibration, Harshness sound vibration roughness) performance.
As shown in Figure 2, tradition Large lining is by inner tube 16, outer tube 17, rubber bodies 18 sulfurations are fixed together, because the inner tube 16 of described Large lining is cylindrical shape inner tube, in the long-term work loading process of Large lining, described rubber bodies 18 is difficult to bear long-term effect of stress with the bind strength of described Large lining inner tube 16, causes the fatigue life of described rubber bodies 18 lower.
The Anti-torque pull rod of prior art, because Large lining inner tube is columnar structured, contriver of the present utility model studies discovery, this columnar structured inner tube only limits to described columnar structured outer peripheral face because of the bonding plane of itself and rubber bodies, bond area is limited, be difficult to bear long-term effect of stress, cause the fatigue life of described rubber bodies lower.Simultaneously, contriver of the present utility model studies discovery, even by the simple cylindrical shape inner tube of amplifying, realize and expand bond area to bear greater impact, but like this, on the one hand, what tend to the described cylindrical shape inner tube to do is larger and heavy, and this has just increased the weight of Large lining inner tube greatly, and cause the waste of material cost, on the other hand, enlarged-area is limited to columnar structured, can not essence solve the problem of impacting compared with large amplitude of bearing.Based on the research of the problems referred to above, contriver of the present utility model has designed a kind of Anti-torque pull rod that comprises X-shaped structure inner tube, the perimembranous of this inner tube is provided with four indent arcwall faces, adopt this design, because of the area of arcwall face larger, can ensure has enough bond areas with rubber bodies (rubber spring and rubber limiting stopper), has greatly improved and the bind strength of rubber, can bear the impulsive force compared with large amplitude; Stress while simultaneously having reduced rubber spring and the work of rubber limiting stopper, the fatigue life of having improved described large end liner cover; And under the prerequisite that ensures enough bolt attachment faces, can reduce to greatest extent the weight of described large end liner cover.
Utility model content
Technical problem to be solved in the utility model is the defects such as the fatigue life for existing Large lining rubber bodies is lower, and a kind of Anti-torque pull rod is provided.
It is as follows that the utility model solves the problems of the technologies described above adopted technical scheme:
A kind of Anti-torque pull rod is provided, comprise the body of rod, large end sleeve and small end sleeve, described large end sleeve and small end sleeve are individually fixed in the two ends of the described body of rod, in described large end sleeve, be provided with large end liner cover, in described small end sleeve, be provided with small end lining, wherein, described large end liner cover comprises that center is provided with the X-shaped inner tube of endoporus, rubber spring and rubber limiting stopper, the perimembranous of described X-shaped strut member is provided with four indent arcwall faces, taking the center shaft of described large end sleeve as z axle, taking the circle center line connecting of described large end sleeve and small end sleeve as x axle, taking simultaneously perpendicular to described x axle and z axle the straight line of crossing the described large end sleeve center of circle as y axle, described four indent arc faces comprise and are positioned on described x direction of principal axis and are symmetricly set in respectively two limiting stopper bearing surfaces of described endoporus both sides and are positioned on described y direction of principal axis and are symmetricly set in respectively two main spring bearing surfaces of described endoporus both sides, on described limiting stopper bearing surface, be fixed with described rubber limiting stopper, on described main spring bearing surface, be fixed with rubber spring, the other end of described rubber spring is fixedly connected with described large end sleeve.
Further, described limited support face is round and smooth cambered surface, and described rubber limiting stopper is connected with described round and smooth cambered surface sulfuration.Like this, while work because of Anti-torque pull rod, the force direction that is subject to of described large end liner cover is the line direction of described large end liner cover and described small end lining.Therefore, mainly power by compression of described rubber limiting stopper.The limited support face of described Large lining X-shaped inner tube is cambered surface, and cambered surface is round and smooth arc surface, and cambered surface Area Ratio plan area is large, larger with the contact surface of limiting stopper, in the time that rubber limiting stopper collides, dispersible the stress of limiting stopper, improve the fatigue life of rubber limiting stopper.
