Abstract
The utility model discloses a trailing arm for an independent rear suspension of a vehicle and aims to overcome the defects of transmission instability of longitudinal applied force and shaking of the existing trailing arm for the independent rear suspension of the vehicle when the vehicle starts and brakes and provide a trailing arm for the independent rear suspension, which has the characteristics of high rigidity and stable force transfer. The key points of the utility model contain that the tailing arm for the independent rear suspension of the vehicle comprises a longitudinal arm rod and connecting sleeves; the longitudinal arm rod is of a triangle frame structure; three vertex angle positions of a triangle frame are respectively provided with one connecting sleeve; the connecting sleeves consist of flanging holes arranged at the vertex angle positions of the triangle frame, sleeves welded with the flanging holes and rubber bushings and shaft sleeves which are sleeved in the sleeves; and the connecting sleeves contain one front connecting sleeve and two rear connecting sleeves. The longitudinal arm rod of the trailing arm for the independent rear suspension of the utility model adopts the triangle frame structure so as to improve comprehensive strength of the longitudinal arm rod, in particular to bending rigidity. The effect of guiding applied force to be transferred along the longitudinal direction of the structure makes transfer of longitudinal force more stable and accurate.
Description
Technical field
The utility model belongs to the car chassis technical field of structures, specifically relates to a kind of independent rear suspension trailing arm of car chassis.
Background technology
Along with the development of society and the raising of living standards of the people, automobile has become a kind of walking-replacing tool in people's life, and the power of automobile conduction simultaneously is stable also to come into one's own day by day with particularity; In existing vehicle independence rear suspension, often use a kind of vertical dowel bar, or claim the rear suspension trailing arm, be mainly and bear the longitudinal force of vehicle at startup and glancing impact, be one of main director element of rear-suspension system application force.Vertically the dowel bar structure is that front end is by rubber bush and body contact, the rear end is connected with rear brake by rubber bush, increase the suspension system longitudinal rigidity, this vertical dowel bar is shaft-like, adopts 2 connection modes, intensity is less relatively, the size of transmitting longitudinal force is slightly inadequate, and vertical dowel bar of 2 connection modes is stable inadequately and accurate to the direction of transmission, the especially conductance of power, the rolling momentum is relatively large, is usually used in the less vehicle rear-suspension system of load carrying ability.China Patent No. ZL200720172024.0 for example, name is called a kind of patent of power actuated vehicle rear suspension trailing arm, it comprises trailing arm arm body, spring pedestal, the fore-end of described trailing arm arm body and rear end part are connected on vehicle frame and the rear-axle casing by front axle and rear axle respectively, trailing arm arm body section form is designed to the form of fracture that notch has the channel-section steel on outer curly limit, connects an arm brace panel in the stressed position of corresponding spring pedestal, trailing arm arm body bottom.The connection mode of this rear suspension trailing arm is as connecting rod, and it can produce side direction and rock under the effect of conicity force, influences the stable and accurate of vertical power transmission.
Summary of the invention
The utility model technical issues that need to address are, overcome existing automobile independence rear suspension trailing arm in the unstable defective of rocking that exists of the longitudinal force conduction of automobile starting and glancing impact, provide a kind of rigidity the big and steady independent rear suspension trailing arm of power transmission.
The purpose of this utility model is achieved by following technical proposals: a kind of automobile independence rear suspension trailing arm, comprise trailing arm bar and adapter sleeve, described trailing arm bar is a triangle mount structure, three angle positions of triangle frame respectively are provided with an adapter sleeve, described adapter sleeve connects the bonded assembly sleeve by the flange hole of each angle position that is located at the triangle frame and with the flange eyelet welding and the rubber bush and the axle sleeve that are sleeved in the sleeve constitute, and described adapter sleeve comprises adapter sleeve behind a preceding adapter sleeve and two.
Be located at the preceding adapter sleeve and the body contact of triangle frame front end, be located at two of triangle back end of frame after adapter sleeve be connected with rear brake.
As preferably, described trailing arm bar adopts steel plate punching press welding to make, and trailing arm bar side is provided with the flanging as additional strengthening.
As preferably, described trailing arm bar side flanging height is 10～30mm.
As preferably, described triangle frame is pressed the setting of right-angled triangle framed structure, and described three adapter sleeves are located at three vertex positions of right-angled triangle; Two adapter sleeves and the trailing arm bar that wherein are located at long square edge constitute main force transmission element, bear longitudinal force, and another adapter sleeve mainly plays the direction that limits application force, make it along long square edge direction conduction, and whole device power transmission are stablized avoid the effect of rocking.
As preferably, described rubber bush and axle sleeve adopt interference fit to be press-fitted with described sleeve to be connected; Rubber vibration isolation cover available buffer impulsive force, particularly buffering automobile start or glancing impact to the impulsive force of vehicle body.
The structure of the triangle box form of described trailing arm bar, compared with the longitudinal tie structure of 2 connection modes, the moment of inertia axial for adapter shaft strengthened greatly, makes the comprehensive strength of trailing arm bar, especially laterally bending stiffness is improved, and this structure can make the longitudinal force conduction more stable, more accurate.
The beneficial effects of the utility model are, the trailing arm bar of independent rear suspension trailing arm adopts the structure of triangle box form, the effect that the bootable application force of this structure longitudinally conducts, make longitudinal force conduction more stable, more accurate, make independent rear suspension trailing arm can be better help improving the performance of vehicle as one of main director element of application force of suspension system.
