Description
Technical field
The utility model belongs to the vehicle engine assembly technical field that suspends, and particularly relates to a kind of Anti-torque pull rod, Anti-torque pull rod mounting structure and vehicle.
Background technology
Car extensively adopts bikini mount supports dynamic assembly at present, and wherein left and right suspends and is connected with vehicle body, and rear-suspending is connected with subframe, and rear-suspending is referred to as Anti-torque pull rod conventionally, and Anti-torque pull rod is arranged in the below of dynamic assembly.Like this, Anti-torque pull rod reduces the vibration of dynamic assembly to the transmission of subframe by Large lining and the little lining at two ends, improves car load NVH (Noise, Vibration, Harshness, noise, vibration and sound vibration roughness) performance.Meanwhile, Anti-torque pull rod, in the time of engine output torque, plays the effect of controlling dynamic assembly displacement and corner.
Existing Anti-torque pull rod is made up of three parts conventionally, as shown in Figures 3 and 4, this Anti-torque pull rod 10a comprises Large lining 1a, little lining 2a and pull bar body of rod 3a, Large lining 1a and little lining 2a are fitted in respectively the two ends of pull bar body of rod 3a, wherein, Large lining 1a is connected (as shown in Figure 1) with subframe 4a, and little lining 2a is connected with change speed gear box or driving engine.As shown in Figure 4, Large lining 1a and little lining 2a structure are identical, and it is to be all integrally formed by inner tube 11a, outer tube 12a and rubber bodies 13a sulfuration.
The height of the dynamic stiffness (the ability of resistance to deformation under live load causes the needed dynamic force of unit amplitude) of subframe 4a and Anti-torque pull rod 10a junction is larger on transmission of vibration impact.The type of attachment of existing Anti-torque pull rod 10a and subframe 4a as shown in Figures 1 and 2, the Large lining 1a of Anti-torque pull rod is arranged vertically (axis of Large lining 1a is in vehicle-height direction), for meeting installation requirement, subframe 4a is designed to the opening hollow structure 7a being made up of upper and lower panel beating 5a and 6a, Large lining 1a is placed in the opening 71a of this opening hollow structure, but, due to this opening hollow structure, 7a is formed by upper and lower panel beating 5a and 6a joint welding, and at opening 71a place, any reinforcement structure is not set, be equivalent between upper and lower panel beating 5a and 6a large area unsettled, thereby under unit dynamic force, the amplitude at this connection location place is larger, in other words, the needed dynamic force of unit amplitude that causes this connection location place is less, the dynamic stiffness of this connection location is less.Therefore, in prior art, axially dynamic stiffness is very low for the connection location (i.e. this opening 71a place) of Anti-torque pull rod 10a and subframe 4a, at driving engine under high rotating speed operating mode, connection location place at Anti-torque pull rod 10a and subframe 4a is produced to larger excitation, this excitation makes generation roar in car, and then causes car load NVH quality to decline, and affects occupant's driving sense and the commodity of vehicle.
