Abstract
The utility model relates to a fixture, especially a novel full floating-type drive axle test fixture. The test fixture is used for car fatigue bench testing and is characterized by high load. The novel full floating-type drive axle test fixture includes an input disc, an output disc and connecting shafts; the input disc is provided with a rear axle hole and input disc bolt holes; the output disc is provided with output disc bolt holes; one end of each connecting shaft is fixed on the input disc, and the other end of each connecting shaft is fixed on the output disc; the connecting shafts are a plurality of steel bars which are parallel to each other; and two ends of each steel bar are uniformly distributed on the concentric circles of the input disc and the output disc. With the plurality of steel bars adopted, the stress area of the connecting shafts can be increased, and larger torque and load can be borne by the plurality of steel bars, and at the same time, materials can be saved.
Description
Technical field
The utility model relates to a kind of fixture, especially a kind of Full-floating drive axle new test fixture for the tired bench test of automobile.
Background technology
Nowadays automobile has been come into huge numbers of families, flourish along with the automobile cause, and market competition all the more encourages, and each auto vendor improves constantly the eyeball that dynamic property, load-bearing capacity and comfortableness of self product etc. attracts client.The automobile bench test is that the first of check automotive safety quality problems closes, and almost is related to driver's life security.The trend improved constantly along with automobile dynamic quality, and product structure is ever-changing, various types of drive axle test fixtures occurred.As a kind of drive axle test fixture, the cylindrical coupling shaft C that comprises input disc A, output panel B, connection input disc A and output panel B, on input disc A, be provided with for connecting the input disc bolt hole D1 of drive axle, be provided with the output panel bolt hole D2 for the joint test platform on output panel B, as shown in Figure 1.The projection of drive axle enters coupling shaft after passing the circular hole in the middle of input disc, due to foundry goods as a whole between input disc, output panel and coupling shaft, when the back axle diameter changes, needs the integral replacing fixture.And coupling shaft can only meet low load, and the practicality of fixture is lower.
The utility model content
Technical problem to be solved in the utility model is: the Full-floating drive axle new test fixture that a kind of top load is provided.
The utility model solves the technical scheme that its technical matters adopts: Full-floating drive axle new test fixture, comprise input disc, output panel, coupling shaft, be provided with input disc bolt hole, rear bridge opening on described input disc, be provided with the output panel bolt hole on output panel, described coupling shaft one end is fixed on input disc, an other end is fixed on output panel, and described coupling shaft is the many rod irons that are parallel to each other, and the rod iron two ends are distributed in respectively on the concentric circles of input disc and output panel.
Described rod iron has five.
Described input disc be provided with the welding gap corresponding with rod iron on output panel, described rod iron is welded to connect by welding gap and input disc, output panel.
Be provided with the through hole concentric with output panel in the middle of described output panel.
The beneficial effects of the utility model are: many rod irons have increased the lifting surface area of coupling shaft, and many rod irons can bear larger moment of torsion, load, can save material simultaneously.
The accompanying drawing explanation
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is vertical view of the present utility model.
Mark in figure: A-input disc, B-output panel, C-coupling shaft, D1-input disc bolt hole, D2-output panel bolt hole, 1-input disc, 11-input disc bolt hole, bridge opening after 12-, 2-output panel, 21-output panel bolt hole, 22-through hole, 3-rod iron.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 2,3, Full-floating drive axle new test fixture, comprise input disc 1, output panel 2, coupling shaft, be provided with input disc bolt hole 11, rear bridge opening 12 on described input disc 1, be provided with output panel bolt hole 21 on output panel 2, described coupling shaft one end is fixed on input disc 1, and an other end is fixed on output panel 2, described coupling shaft is the many rod irons that are parallel to each other 3, and rod iron 3 two ends are distributed in respectively on the concentric circles of input disc 1 and output panel 2.
To follow the drive axle rotation in process of the test due to test fixture, if adopt removable the connection between rod iron 3 and input disc 1, output panel 2, strength of joint is lower, in order to improve the strength of joint between rod iron 3 and input disc 1, output panel 2, improve the moment of torsion of test fixture, as being preferred embodiment, described input disc 1 be provided with the welding gap corresponding with rod iron 3 on output panel 2, described rod iron 3 is welded to connect by welding gap and input disc 1, output panel 2.By the welding gap, rod iron 3 is welded on input disc 1, output panel 2, improves bonding area, increase the strength of joint of rod iron 3.
In the situation that meet bulk strength and the moment of torsion of test fixture, in order to save material, as preferred embodiment, as shown in Figure 2,3, in the middle of described output panel 2, be provided with the through hole 22 concentric with output panel 2.
