Abstract

The utility model discloses a vehicle torsion beam tester, in particular to a tester which tests the mechanical property of a torsion beam. Aiming to the defects in the prior test technology, the utility model provides a torsion beam tester which tests the performance of the torsion beam in a whole vehicle and has short period and low cost, and is characterized in that a torsion beam suspension frame assembly is connected with a bench (1) through hard connecting and soft connecting. A loading device (3) which is fixed on the bench through a base (3a) thereof comprises three loading units which are mutually perpendicular and are connected with the base through universal connecting, the positions of the two sides of the torsion beam suspension assembly which are equipped with wheels are respectively equipped with connecting devices (2), and the connecting devices are connected with the loading units of the loading device through the universal connecting. A torsion beam suspension frame is imposed loads through the loading device, the force condition of the torsion beam in the whole vehicle is simulated in the laboratory environment, which can be used for static force, fatigue and strength tests during the design making process of the torsion beam.

Description

Automobile torsion beam test unit

Technical field

The utility model relates to automobile torsion beam test unit, especially a kind of test unit of testing at the mechanical property of automobile torsion beam.

Background technology

The semi-independent suspension of torsion girder-like is a rear overhang hanging hang structure commonly used at present, realize that by the trailing arm of the torsion beam left and right sides wheel is connected with the rigid of vehicle frame, be connected with the soft of vehicle frame and finish wheel, thereby play the effect of supporting vehicle body by vibroshock and damping spring; The trailing arm of torsion beam can swing up and down so that by vibroshock and damping spring absorbing vibration, play the effect of shock-absorbing around rigid tie point; The crossbeam of torsion beam is crossed when curved as vehicle when the left and right wheels unbalance stress, adjusts the both sides wheel to improve vehicle performance by reversing.Therefore torsion beam is a critical component in the semi-independent suspension of torsion girder-like, and it plays power transmission, stressed and the effect that is connected the balance both sides, and suspension is related to vehicle performance and comfortableness.

Therefore for the vehicle that has adopted the semi-independent suspension of torsion girder-like, in its design, manufacture process, all need its torsion beam is tested.But for the torsion beam test, do not have unified test method at present, only can carry out torsion beam is carried out traditional structural member mini-test,, or carry out vehicle road test and verify as intensity, testing fatigue etc.

But the mini-test of torsion beam can not be tested at the performance of torsion beam in car load; And vehicle road test must just can carry out on the complete vehicle test field, the expense height, and the time cycle is long.

The utility model content

In order to overcome the deficiency of existing experimental technique, technical problem to be solved in the utility model provides a kind ofly tests at the performance of torsion beam in car load, and the automobile torsion beam test unit that the cycle is short, expense is low.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of automobile torsion beam test unit is characterized in that: automobile torsion beam suspension assembly according to the car load matching requirements with being connected of stand; Charger is fixed on the stand by its base, and charger comprises three vertical mutually loading units that also are connected with base by universal connection; The position that wheel is installed in automobile torsion beam suspension assembly both sides is separately installed with coupling arrangement, and coupling arrangement is connected with the loading unit of charger by universal connection.

So just can apply the load of an any direction by three orthogonal loading units to torsion beam, the stressing conditions of simulation torsion beam in car load under laboratory environment, and can finish static(al), fatigue and the strength test of torsion beam by different loading procedures, thereby saved time and the expense of test greatly, and assembling, convenient disassembly.

Fig. 3 is the vertical view of charger.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Automobile torsion beam suspension assembly 4 is pressed the suspension matching requirements of car load, by being suspended on the stand 1 bolt 4a rigid connection of reaching and soft connection of forming by damping spring 4b and vibroshock 4c, the position that wheel is installed in its left and right sides is separately installed with coupling arrangement 2, charger 3 is fixed on the stand 1 by its base 3a, correspondingly with coupling arrangement 2 be provided with about also being, each charger 3 all comprises vertical loading unit 3b, horizontal loading unit 3c, vertical loading unit 3d, each loading unit all is made up of fluid cylinder, its cylinder sleeve one end is connected with base 3a by universal connection, and piston rod one end is connected with coupling arrangement 2 by universal connection.

By vertical loading unit 3b, laterally loading unit 3c, vertical loading unit 3d can apply respectively vertically torsion beam 4d, horizontal, vertical load, perhaps apply the resultant load of an any direction by the cooperation between the loading unit, thereby reach the stressing conditions of simulation torsion beam in car load under laboratory condition, and can finish static(al), fatigue and the strength test of torsion beam 4d, thereby the time and the expense of test have been saved greatly by different loading procedures.

The universal connection at loading unit two ends then can guarantee the direction of power and the transmission of power in whole loading procedure, be not subjected to the influence of torsion beam 4d distortion, and universal connection can be bulb connection, joint spider connection, slide block connection etc.

Loading unit can also use cylinder, screw mandrel or other linear motion devices to replace except can using the hydraulic amplifier device, and perhaps the loading structure of forming with linear motion device, lever, connecting rod replaces.And loading unit direction is set, except can be vertically, laterally, vertical, also can be other form, just can be as long as three loading units are vertical mutually by the loading effects of synthetic acquisition any direction.
