Embodiment
Following content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
As shown in Figure 1, simulation air spring of end gate of real vehicle test unit of the present utility model comprises framework 10, cylinder 11, cylinder hinge seat 12, fork hinge 13, fork 14, imitative door fork 15, imitative door fork hinge 16 is installed crossbeam 17, ballast box 18, impact damper 19, contiguous block 20, cylinder tab hinges 21, roller 22, stay cord 23, last tie point 24 and following tie point 25.
Described cylinder hinge seat 12, imitative door fork hinge 16, fork hinge 13 are installed on the framework 10 of trough of belt by bolt, and can move forward and backward along groove within the specific limits.
Fork 14 also is the section bar of trough of belt, and 11 hinges of cylinder are connected with fork 14 by bolt and can adjust within the specific limits along fork 14 grooves, is used for adjusting fork 14 and reaches real vehicle switch door state with the pendulum angle of imitating door fork 15.
The section bar that described installation crossbeam 17 also is a trough of belt is connected on the fork 14 of trough of belt by bolt, unclamp bolt, can move along fork 14 within the specific limits, tie point 24 is by on bolt and the crossbeam 17 that trough of belt is installed on the air spring, following tie point 25 also is connected on the contiguous block 20 of trough of belt, contiguous block 20 is installed in by bolt in the groove of framework 10, can be stepless within the specific limits adjustable along groove, thus reach the requirement of simulating the real vehicle mounting points.
By regulating the parallel distance of tie point 24 and imitative hinge axle center vertical line, can change the self-opening door and the self-closing door angle of imitative door fork 15.
Roller 22 is installed on the described fork 14 is used for promoting imitative door fork 15, the friction force that produces when reducing by two fork 14 relative motions.
This fork 14 is flexible coupling by stay cord 23 with imitative door fork 15, and car door can freely be risen with the air spring lifting force of self after rising to certain angle, fully simulates the action of actual car door.
