Embodiment 1

[0031] Refer Figure 1-7 A vibration test device that adjusts the car posture, includes a casing 101, further comprising a support shaft 201, and the support shaft 201 is located at the top of the casing 101 and is connected to the casing 101 through the attitude adjustment mechanism, and the attitude adjustment mechanism is connected to the casing The 101 extends to the top of the casing 101, the attitude adjusting mechanism includes; lifting mechanism connected to the casing 101 and the horizontal pitch adjustment mechanism attached to the lifting mechanism and extends the top of the casing 101.

[0032] The support shaft 201 is two of the symmetrical design, and is connected to two adjustment ends of the horizontal spacing adjustment mechanism, each of which is rotated over each of the support shafts 202, and the support shaft 201 and the test wheel 202 are passed. The bearing connection is provided with a test assembly on the test wheel 202.

[0033] At the time of the test, th...

Embodiment 2

[0039] Refer Figure 1-7 Further, in the basis of Example 1, it is further.

[0040] This example discloses a lifting mechanism including a second threaded rod 4 that is rotatably coupled to the inner wall of the casing 101, the second threaded rod 4 is a double threaded rod, and the thread is rotated in the second thread. The two threaded blocks 401 on the rod 4, respectively, respectively, respectively, respectively, respectively, on both ends of the second threaded rod 4 in which the second threaded rod 4 is rotated, and the upper and lower slides are attached to the lifting plate 3 of the inner wall of the casing 101, the bottom portion of the lifting plate 3 Turn two connecting rods 402 connected to the symmetric design, each of the connecting rods 402 is rotated on one end of the lifting plate 3, respectively, and the second threaded rod 4 is driven by a driving source, the second threaded rod 4 When rotating, the two threaded blocks 401 are simultaneously moved in opposite d...

Embodiment 3

[0045] Refer Figure 1-7 Further, in the basis of Example 2, it is further,

[0046] This example discloses a horizontal pitch adjustment mechanism including a first threaded rod 301 that is rotatably coupled to the lifting plate 3, and the first threaded rod 301 is a double threaded rod, and the threads threaded both ends, and threads. The two first support plates 2 connected to the first threaded rod 301, two first support plates 2 are respectively symmetrically connected to two support shafts 201 of the opposite first thread 301, symmetric design, respectively. The support shaft 201 can be fixed to the first support plate 2, respectively, and can be rotatably coupled to the first support plate 2, and the first threaded rod 301 can be rotatably coupled to the first support plate 2.

[0047] A slot is provided at the top of the casing 101, and the first support plate 2 slides in the slot.

[0048] Depending on the size of the car wheel, when the pitch of the two test wheel 202 is ...

Abstract

The invention discloses a vibration testing device capable of adjusting the posture of an automobile, and belongs to the technical field of automobile detection, the vibration testing device capable of adjusting the posture of the automobile comprises a box body and a supporting shaft, the supporting shaft is located at the top of the box body and is connected with the box body through a posture adjusting mechanism, and the posture adjusting mechanism comprises a driving mechanism and a driving mechanism; the lifting mechanism is connected in the box body; the horizontal distance adjusting mechanism is connected to the lifting end of the lifting mechanism and extends out of the top of the box body; the two supporting shafts are symmetrically designed and are respectively connected to two adjusting ends of the horizontal distance adjusting mechanism, and each supporting shaft is rotatably connected with two testing wheels; in the testing process, according to testing requirements, the posture of the automobile can be flexibly adjusted through the posture adjusting mechanism, the vibration amplitudes of the automobile at different positions when the automobile is uphill or downhill can be tested, and the damage degrees of front and rear tires of the automobile when the automobile vibrates at different postures can be tested.

Description

Technical field [0001] The present invention relates to the field of automotive testing, and more particularly to a vibration test device that adjusts the car attitude. Background technique [0002] Since entering the new century, with the rapid development of my country's economy, people's living standards have increased rapidly, and private cars are also increasingly popular. The market is increasing in private cars. The production capacity of the majority of car companies is also increasing. The improvement of production capacity, and more strict requirements for quality requirements, so the vibration test is required before the whole vehicle is exported, and the vibration amplitude of the body is detected. [0003] However, in the current market, the existing vibration test device of the existing car attitude is unable to adjust the car attitude according to the test demand, resulting in the undetectable test, or the car is in the upper slope, or the downhill, different posit...
