Embodiment 1

[0028] see figure 1 , figure 2 As shown, the embodiment of the present invention provides a simple measuring tool for the empty stroke of the buffer block of the automobile suspension, which can be used to measure the empty stroke of the buffer block of the real vehicle, obtain more accurate wheel jump parameters, and improve the follow-up simulation model. The precision of the suspension provides a scientific basis for the force distribution of the vehicle. The measuring tool at least includes: a measuring panel 1 , a lower sliding block 2 , an upper sliding block 3 , an upper scale 4 , a lower scale 5 and other components.

[0029] Specifically, as a preference, the measuring panel 1 is made of a metal plate whose cross-section is in the shape of a groove 1-1, and the upper plane of the groove 1-1 extends two fins 1-3, and the two fins 1-3 and the groove 1-1 are integrally molded, or can be welded or riveted together after single molding; the two fins 1-3 are arranged sym...

Embodiment 2

[0035] The measuring panel 1 can also be designed as a retractable structure, which is convenient for measuring the situation where the length of the empty stroke exceeds the range of the measuring panel. Increased versatility of the tool. In most cases, the whole vehicle is placed flat on the ground, and the dead weight of the body makes the empty stroke of the buffer block in a compressed state from the beginning, so the original length of the measuring panel should be able to meet the measurement requirements of the empty stroke under most loading conditions. All the other structures and methods of use are the same as in Embodiment 1.

[0036] The serial numbers of the above embodiments of the present invention are for description only, and do not represent the advantages and disadvantages of the embodiments.

[0037] In addition, the embodiment of the present invention has simple structure, low manufacturing cost, convenient use, strong practicability, and easy populariza...

Abstract

The invention discloses a simple measuring tool of a vehicle suspension buffer block air travel and belongs to the field of vehicle suspensions. The measuring tool at least comprises a measuring panel, a downward shift block, an upward shift block, an upper scale and a lower scale which are used for measuring the buffer block air travel of the vehicle suspension. The tool can measure the distance between the upper end surface of a shock absorber outer cylinder and an upward jumping buffer block when a real vehicle is in a loading condition at present to obtain an accurate round jump parameter of a real vehicle buffer block air travel. The round jump parameter of the buffer block air travel can be measured to judge whether the whole vehicle loading state is normal, so as to be beneficial to improving the measurement accuracy of a following-up simulation suspension model and real measured suspension model parameters, so that a scientific basis for the force distribution of the whole vehicle can be provided.

Description

technical field [0001] The invention relates to the field of automobile suspension, in particular to a simple measuring tool for the empty stroke of the buffer block of the automobile suspension. Background technique [0002] The automobile suspension consists of three parts: elastic elements, shock absorbers, and force transmission devices. These three parts play the roles of buffering, vibration reduction, and force transmission respectively. The shock absorber is to accelerate the attenuation of the vibration of the car body, mainly including the coil spring, the outer cylinder of the shock absorber, the piston rod of the shock absorber, the jump buffer block, etc.; in order to prevent the impact caused by the "breakdown" of the car suspension, the When the wheel jumps to a certain stroke, a highly nonlinear elastic element is connected in parallel with the coil spring, which is the buffer block, and the suspension stroke is limited by the punch block to absorb the impact...
