Technical field
The utility model relates to a kind of device that the automotive axle torture test detects that is used for.
Background technology
Vehicle bridge also claims axletree, is a kind of automobile component, and its middle part links to each other with vehicle frame (or monocoque body) by suspension, and automotive wheel is installed at two ends.Its function is to transmit all directions acting force and moment of flexure that is produced and moment of torsion between vehicle frame or monocoque body and the wheel.When running car, vehicle bridge can be subjected to very big acting force and moment, so vehicle bridge when producing, need reach certain requirement to the permanance of himself stressed fatigue.In the prior art, the improvement by material and processing technology etc. improves the vehicle bridge fatigue durability usually, strengthens its anti-fatigue performance.But, in the prior art, whether the automotive axle permanance of producing is satisfied the running car requirement on earth, also there is not a kind of detection means of criterion of acceptability.
So how to design a kind of vehicle bridge fatigue durability that can detect judging whether the vehicle bridge performance is outstanding, and feed back the test unit that whether has defective when judging the vehicle bridge development and Design, just become this area problem demanding prompt solution.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of vehicle bridge fatigue experimental device that can conveniently detect the vehicle bridge fatigue durability in order to overcome above-mentioned the deficiencies in the prior art.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of vehicle bridge fatigue experimental device, its characteristics are, comprise horizontally disposed base, vertically be arranged at two liftable portal frames of both sides on the base, level frame is located at two crossbeams on the portal frame, vertically be arranged at two actuator between two portal frames on the base, the distance of two actuator needs to mate with the length of vehicle bridge to be measured when specifically being provided with; Application of force place, described actuator upper end is provided with anchor clamps a, and anchor clamps a is used to be connected and fixed the two ends of vehicle bridge to be measured and as application of force driving member; Described crossbeam is provided with two anchor clamps b, and anchor clamps b is used to be connected and fixed the middle part of vehicle bridge to be measured.
In the technique scheme, described anchor clamps a can be optimized for following structure: anchor clamps a is provided with a link that links to each other with application of force place, actuator upper end, with a horizontally disposed stiff end, described stiff end is used to be connected and fixed the two ends of vehicle bridge to be measured, more particularly, described link is hinged on the start head of actuator upper end by a ball-type link dish, the benefit of this ball-type connection part structure is the actual installation situation that has reflected vehicle bridge more really, the real load that can accurately simulate vehicle bridge; Reliable bolt, packing ring, nut are connected between link and the stiff end; Described stiff end is provided with a groove and the steering knuckle at vehicle bridge two ends can be packed in the groove and can adopt bolt to pass steering knuckle and carry out fastening location.
Described anchor clamps b also can be optimized for following structure: anchor clamps b is provided with the clamping part and the clamping part that is clamped and connected with vehicle bridge that are clamped and connected with crossbeam, connects by bolt between two clamping parts.More particularly, described clamping part all is set to the structure of holding tank, adopts bolt, the fastening location of nut again after can being sandwiched in crossbeam or vehicle bridge in the groove, unclamp bolt, nut like this after, anchor clamps b can reorientate after moving on crossbeam and the vehicle bridge.
When the utility model uses, the vehicle bridge two ends are fixed by bolts on the anchor clamps a, the middle part is clamped on the two anchor clamps b, start two actuator, actuator by anchor clamps a to the vehicle bridge application of force, thereby the imitation vehicle bridge is subjected to force environment when running car, the size of the actuator application of force appropriately is set, observing vehicle bridge in certain cycle index or after the time has phenomenons such as flawless, fracture to occur, can detect judge the vehicle bridge fatigue durability can quality.
Than prior art, the utility model can make things convenient for the quality of judging automotive axle fatigue durability energy exactly, can and then judge the quality of vehicle bridge performance, and feed back whether there is defective when judging the vehicle bridge development and Design that convenient design is optimized to vehicle bridge; The utility model also possesses advantages such as simple in structure, with low cost, simple to operation simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
