Изобретение относитс к гаражному оборудованию , а более конкретно к стендам дл испытани гидравлических амортизаторов , проводимого при техническом обслуживании и ремонте автомобилей.The invention relates to garage equipment, and more specifically, to stands for testing hydraulic shock absorbers for car maintenance and repair.

Известен стенд дл испытани гидравлических амортизаторов, содержащий основание в виде плиты, на которой укреплена стойка, несуща верхний зажим и записывающий механизм, подпружиненную щарнирнорычажную передачу, жестко св занную с платформой, несущей нижний зажим, и электродвигатель с эксцентриковым валом 1.A stand for testing hydraulic shock absorbers is known, comprising a base in the form of a plate on which a stand is fastened, carrying an upper clip and a recording mechanism, a spring-loaded toggle gear, rigidly connected to the platform carrying the lower clip, and an electric motor with an eccentric shaft 1.

Недостатками стенда вл ютс низка точность и производительность, а также неполна информаци о состо нии амортизатора .The disadvantages of the stand are low accuracy and performance, as well as incomplete information about the state of the shock absorber.

Целью изобретени вл етс повышение производительности труда путем ускорени процесса испытани и повыщение точности и нагл дности информации о состо нии амортизатора .The aim of the invention is to increase labor productivity by speeding up the testing process and increasing the accuracy and accuracy of information on the state of the shock absorber.

Указанна цель достигаетс тем, что стойка снабжена микропереключател ми, коромыслами и штоками, а платформа - кулачками дл взаимодействи с упом нутымиThis goal is achieved by the fact that the rack is equipped with microswitches, rocker arms and rods, and the platform with cams for interacting with said

микропереключател ми через коромысла и штоки.microswitches through rockers and rods.

На фиг. 1 изображен схематически стенд, общий вид; на фиг. 2 - схема монтажа микровыключателей.FIG. 1 shows a schematic of the stand, a general view; in fig. 2 - installation diagram of microswitches.

Claims

The stand for testing hydraulic shock absorbers contains a base in the form of a plate 1, on which a double-support post 2, an electric motor 3, an eccentric shaft 4 rigidly connected with an electric motor 4 with a flywheel 5 mounted on it, is fixed. the rigidity of which is regulated by a screw 8, with a handwheel 9, and on an articulated gear transmission 10; supported by a vertical lever-swivel lever 10 platform 11, on which spring 12 and a shock absorber 13 are installed, fixed stop 14 and clip 15, actuated by a pneumatic chamber 16. The shock absorber rod 13 is attached by a handwheel 17 to the hinge 18 of the stand console 19. The recording device for removing the working diagram of the shock absorber 13 under test consists of an actuator 20, a screen 21 and a recorder 22. The electrocontact device contains four microswitches 23 mounted on a two-post rack 2 and two cams 24 rigidly connected to the working platform 11. Each Of the four microswitches 23, it operates by means of a similar device containing a rocker 25, which rotates around an axis 26 and acts on a spring-loaded pusher 27, which directly acts Microswitch contact. 23. The adjustment of the microswitches is carried out with screws 28. The stand operates as follows. The shock absorber 13 being tested is clamped by the stop 14 and the clip 15 actuated by the pneumatic chamber 16. The shock absorber rod 13 is fastened to the hinge 18 of the stand console 19 by means of the handwheel 17. When the electric motor 3 is turned on, the flywheel 5 is unwound. In order to obtain damped oscillations, the electric motor is switched off immediately after its output to the nominal mode. After this, the hinged-gear transmission 10 operates at the expense of the energy of the flywheel 5 and informs the oscillations to the test shock absorber i ;. When the oscillations decay, the system enters the resonant frequency, and the shock absorber under test gites it. Depending on the elastic qualities of the shock absorber, the amplitude of the resonant oscillations will be different. Her study provides an opportunity to judge the suitability of the shock absorber. Claims The stand for testing hydraulic shock absorbers, comprising a base in the form of a plate, on which a stand is fastened, carrying an upper clip and a recording mechanism, a spring-loaded pivot-lever gear, rigidly connected to the platform carrying the lower clip, and that, in order to increase labor productivity by speeding up the testing process and improving the accuracy and consistency of information about the state of the shock absorber, the said rack is equipped with a microswitch bodies in E, and rockers schtokami and .platforma - cams for cooperating with said rocker arm through a microswitch mi and stocks.
