Description

The bench test test unit of a kind of front suspension and lower swing arm
Technical field
The utility model relates to a kind of bench test test unit, especially relates to the bench test test unit of a kind of front suspension and lower swing arm, belongs to bridge car component test equipment manufacturing technology field.
Background technology
McPherson strut be the world today use the most widely car front suspension one of hang.McPherson strut is comprised of volute spring, vibroshock, triangle lower swing arm, and most vehicles also can add QS.
The structural relation of McPherson strut is; The vibration damper upper end connects with the vehicle frame hinge, lower end and steering knuckle connect, volute spring is enclosed within outside the vibration damper, lower swing arm is inner to be connect with the fore sub frame hinge, outer end and steering knuckle connect, and vibroshock play the guiding role, and is offset to front, rear, left and right in the time of can avoiding volute spring stressed, restraining spring can only be done the vibration of above-below direction, and soft or hard and the performance that can set suspension with stroke length and the degree of tightness of vibroshock.
Lower swing arm one end is connected with steering knuckle by ball stud, and the other end and fore sub frame hinge connect, and lower swing arm bears from the lateral impact of wheel and impact of collision load, and lower swing arm also passes to fore sub frame with load simultaneously.
Each large automobile factory carries out fatigue life test to car fore sub frame and lower swing arm at present, mainly is to carry out bench test on the body in white by McPherson strut, steering knuckle, fore sub frame etc. are contained in.Employing mostly is the axletree coupling scheme and carries out vertical, vertical and the side load loading to the front overhang frame system, the whole automobile front suspension system lifetim of comprehensive verification.
For the Automobile Parts Industry of producing car fore sub frame and lower swing arm, adopt the test method that is installed on the body in white.Its advantage is that the installation ratio of rigidity of fore sub frame and lower swing arm and vehicle body and other parts is than the Pass Test situation.But its shortcoming is also fairly obvious: the first, must vehicle body make and just can carry out the test of fore sub frame and lower swing arm afterwards; The second, the damage of components that own enterprise do not pay close attention to often occurs and cause test to carry out; Three, experimentation cost increases.
In order to overcome above-mentioned shortcoming, also there is the fore sub frame of employing to fix by unit clamp, then, by actuator lower swing arm is applied the test method that vertical and horizontal load is carried out bench test.This test method can overcome above-mentioned shortcoming, but in order to obtain correct stress distribution, fore sub frame installation rigidity and real vehicle is approached.And actual conditions are, lower swing arm and fore sub frame hinge connect, because this hinge is vertical and vertical rubber bushing, cause lower swing arm can only bear very little vertical load, when lower swing arm being applied vertical or side load, lower swing arm has the trend that moves up and down, and causes vertical and horizontal load applying difficulty.
Therefore, expectation is in the art, a kind of test fixture device that solves the shortcoming in above two kinds of test methods or can greatly improve above-mentioned shortcoming is provided, and then the test fixture device of car front suspension frame simple in structure, reliable, lower-cost and the torture test of lower swing arm vertical and horizontal is provided.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of and can easily impose the front suspension of vertical or horizontal load and the bench test test unit of lower swing arm to lower swing arm.
For solving the problems of the technologies described above the technical scheme that adopts be: the bench test test unit of a kind of front suspension and lower swing arm, comprise actuator, also comprise the ball stud anchor clamps on the fixing bulb pin rod that is socketed in lower swing arm, actuator, imposes laterally or trial load longitudinally to the ball stud of lower swing arm in surface level by described ball stud anchor clamps.
Further be, also comprise vertical position limiting structure, described vertical position limiting structure is positioned at the top of ball stud anchor clamps, and its upper end is connected with the stationary fixture of outside, and the lower end is connected with the top of ball stud anchor clamps.
Further be, described vertical position limiting structure comprises bulb spherical plain bearing rod end, lower bulb spherical plain bearing rod end and vertical duplex-head double-screw bolt, upper bulb spherical plain bearing rod end and lower bulb spherical plain bearing rod end are as a whole by the vertical duplex-head Stud connection, the free end of described vertical position limiting structure by upper bulb spherical plain bearing rod end is connected with the stationary fixture of outside, and the free end by lower bulb spherical plain bearing rod end is connected with the top of ball stud anchor clamps.
Further be, also comprise horizontal studs, actuator is connected with the ball stud anchor clamps by described horizontal studs, and passes through described horizontal studs and ball stud anchor clamps, imposes laterally or trial load longitudinally to the ball stud of lower swing arm in surface level.
Further be, also comprise set bolt, the ball stud anchor clamps that are socketed on the bulb pin rod of lower swing arm are fixed by described set bolt.
Further be that during test clamping, the ball stud base on ball stud anchor clamps and the described lower swing arm fits tightly.
The beneficial effects of the utility model are: the ball stud anchor clamps on the bulb pin rod that is socketed in lower swing arm that can fix are set, then, make the actuator that produces load by the described ball stud anchor clamps on the fixing bulb pin rod that is socketed in lower swing arm, trial load is applied on the ball stud, pass to again lower cantalever, thereby realized very easily the vertical or horizontal torture test of lower cantalever.Further, for when applying vertical or horizontal load to lower cantalever, can reduce the amplitude that lower swing arm moves up and down, the utility model also comprises vertical position limiting structure, because the upper end of vertical position limiting structure is connected with the stationary fixture of outside, the lower end is connected with the top of ball stud anchor clamps, like this, when actuator applies vertical or horizontal load by ball stud anchor clamps and ball stud to lower cantalever, just can effectively reduce the amplitude that moves up and down of ball stud anchor clamps, and then reach and reduce the move up and down purpose of amplitude of lower swing arm.
