Abstract
The utility model aims to provide a test fixture for a front auxiliary frame control arm, which can carry out a test by installing the front auxiliary frame control arm according to a connection mode of the control arm on a finished automobile. In order to realize the test fixture for the front auxiliary frame control arm and connect the front auxiliary frame control arm according to the connection mode on the finished automobile, the front auxiliary frame control arm is provided with two bushings and a ball head. The test fixture comprises a bushing fixture connecting the two bushings and a ball head fixture connecting the ball head, wherein the ball head fixture is provided with a round hole through which a connecting pin of the ball head penetrates, and the connecting pin is provided with an annular groove. The test fixture is characterized in that the ball head fixture is further provided with two bolt holes perpendicular to the round hole, the two bolt holes penetrate through the annular groove from two sides of the connecting pin respectively, and two bolts penetrating through the two bolt holes penetrate through the annular groove so as to enable the ball head and the ball head fixture to be relatively fixed in the vertical direction.
Description
Technical field
The utility model relates to fore sub frame control arm test fixture.
Background technology
Car is in the actual travel process, and the control arm on the fore sub frame mainly is subjected to the load of both direction: X, Y both direction.And in the simulating vehicle process of the test, need to rely on anchor clamps that control arm bulb one end is coupled together according to the car load mounting means, these anchor clamps require the actual load that is subjected to of energy simulated automotive simultaneously, and the load that actuator is exported accurately is delivered to anchor clamps, the actual motion environment of while reproducing control arm on car load.
As shown in Figure 1, what existing technology relied on is that common circular hole anchor clamps 10 are connected (connecting pin that is control arm bulb 12 is inserted in the circular hole of circular hole anchor clamps) with control arm bulb 12, there be not the connected mode of bulb 12 on car load according to control arm 11, can not lock the bulb 12 of control arm, and its vertical disturbance that is subjected to actuator (it passes through circular hole 101 and is connected with anchor clamps), can not control, bulb 12 and anchor clamps 10 are loosening easily in the process of the test, when the power of actuator is loaded into anchor clamps 10, bulb 12 produces relative multivariant motion with anchor clamps 10, because this bolt hole of the bolt hole 100(on the anchor clamps 10 passes for bolt, be used for fixedly bulb) do not match with bulb, cause bolt that the bulb 12 on the control arm is caused very big damage, and the bolt hole 100 to anchor clamps 10 has very big wearing and tearing, cause test findings and real train test result to differ too big, therefore can not reflect that real train test causes the situation of damage to control arm.
The utility model content
The purpose of this utility model is to provide a kind of fore sub frame control arm test fixture, and it can be installed the fore sub frame control arm according to the connected mode of control arm on car load and test.
For realizing the fore sub frame control arm test fixture of described purpose, be used for connecting the fore sub frame control arm according to the connected mode on the car load, this fore sub frame control arm has two linings and bulb, this test fixture comprises the lining anchor clamps that connect two linings and the bulb anchor clamps that connect this bulb, these bulb anchor clamps have the circular hole that the connecting pin for this bulb passes, this connecting pin has annular groove, be characterized in, these bulb anchor clamps also have two bolts hole of vertical this circular hole, this two bolt hole passes through this annular groove from the both sides difference arc groove of this connecting pin, two bolts that pass this two bolt hole pass this annular groove, so that this bulb and bulb anchor clamps are in vertical relative fixed.
Because bulb and bulb anchor clamps are restrained in vertical degree of freedom, therefore can the fore sub frame control arm be installed according to the connected mode of control arm on car load and test.

Fig. 2 is that the axle of the bulb anchor clamps of the utility model fore sub frame control arm test fixture is surveyed view.
Fig. 3 is that the axle of a lining of fore sub frame control arm is surveyed view.
Fig. 4 is that the axle of another lining of fore sub frame control arm is surveyed view.
Fig. 5 is the synoptic diagram of the bulb of fore sub frame control arm.
Fig. 6 is the synoptic diagram that the bulb anchor clamps are connected with bulb.
Fig. 7 synoptic diagram that to be the fore sub frame control arm be connected according to the car load mode with fore sub frame control arm test fixture.
Embodiment
As shown in Figure 2, bulb anchor clamps 20 are L-shaped, have the circular hole 200 that the connecting pin for bulb passes, and also have two bolts hole 203,204 of vertical circular hole 200.
As shown in Figure 3, a lining 31 of the control arm of fore sub frame has the hole 310 that can supply bolt to pass, and the lining anchor clamps 60 in Fig. 7 just pass hole 310 by bolt and are connected with lining 31.
As shown in Figure 4, a lining 32 of the control arm of fore sub frame has the hole 320 that can supply bolt to pass, and the lining anchor clamps 50 in Fig. 7 just pass hole 320 by bolt and are connected with lining 32.
As shown in Figure 5, the connecting pin of bulb 33 has ring groove 330, in conjunction with Fig. 2 and Fig. 6, when the connecting pin of bulb 33 penetrates in the circular hole 200 of bulb anchor clamps 20, bolt 205,206 penetrates into respectively in the bolt hole 203,204, bolt 205,206 can pass ring groove 330, does not relatively move so that bulb 33 and bulb anchor clamps 20 vertical fixing, do not have.
As shown in Figure 7, lining anchor clamps 60 are connected with lining 31, and lining anchor clamps 50 are connected with lining 32, and adopt bolt to carry out fastening, then with lining anchor clamps 60,50 and control arm 30 be connected in the lump on the pedestal 40, adopt bolt that lining anchor clamps 60,50 all are fastened on the pedestal 40.
This subframe control arm test fixture is the true property of the accurate result of warranty test to a great extent, shortens the test period, the human and material resources when reducing installation and easy for installation.
