The specific embodiment
As shown in the figure, a kind of hydraulic motor beam self-locking suspension device, comprise moving beam 2 and be arranged on the entablature 1 that moves beam 2 tops, the two ends of moving beam 2 end faces are arranged with motion hanging member 4, and the two ends of entablature 1 are arranged with the fixedly latching member 3 that cooperates with motion hanging member 4; Described motion hanging member 4 comprises lifting eye seat 401 and top wheel 402, and lifting eye seat 401 is bolted on the moving beam 2, and top wheel 402 is arranged on the top of lifting eye seat 401; Described fixedly latching member 3 comprises outstanding connecting rod 301, pendulum 302 and cam 303, outstanding connecting rod 301 is hinged with entablature 1, outstanding connecting rod 301 bottoms are hinged by hinge and pendulum 302 and cam 303, and the global shape of pendulum 302 is triangle, and pendulum 302 is connected with outstanding connecting rod 301 by extension spring 5; Cam 303 is arranged on the track that wheel 402 servo-actuated beams 2 in top move both vertically, and is connected with pendulum 302 by torsion spring 8, and cam 303 passes through simultaneously two extension springs of connecting and is connected with outstanding connecting rod 301 lower end bottom portion of groove; Pendulum 302 belows are provided with the cylindrical protrusions 6 that the crotch section with lifting eye seat 401 articulates.
Cam 303 be shaped as the reducing arc, cam 303 materials are high-abrasive material.
The position that contacts with cam 303 on the top wheel 402 is provided with the recessed tooth of circular arc, and top wheel 402 materials are high-abrasive material.
Outstanding connecting rod 301, pendulum 302 and lifting eye seat 401 adopt the steel-casting moulding.
The lower surface of lifting eye seat 401 crotch sections and the upper surface of cylindrical protrusions 6 are provided with the multistage parallel plane 7 that is meshed, and multistage parallel plane 7 is through overcure and Wear-resistant Treatment.
At first, when motion hanging member and moving beam rise together, rise to cam position (such as Fig. 3); top wheel beginning contacts with cam; then cam overcomes the pulling force of extension spring, drives pendulum and rotates together, makes pendulum enter the hover point position; shown in (such as Fig. 4); if this moment moving beam in working order the time, it is not shut down in Fig. 4 position, can realize that the moving automatic self-locking of beam hovers over this position; thereby realize moving beam in the function of hovering of limes superiors position, the guiding of protection master cylinder and the effect of sealing.When moving beam is in running order, it directly rises and enters Fig. 5 position, rise for the continuation of moving beam in this position, then along with the rising of moving beam, beginning is rotated toward disengaged direction by the pulling force effect of extension spring, i.e. counter-rotation for pendulum and cam, when moving beam rises to extreme position, cam and pendulum are moved to initial position by extension spring, i.e. complete disengaged position, and this is Fig. 6 position.At this moment moving beam begins reverse descending action, when coming downwards to Fig. 7 position, moving beam contacts with cam for the top wheel, then the cam elastic force that overcomes torsion spring and extension spring begins the hinge point rotation around outstanding connecting rod, when moving beam went downwards to Fig. 8 position, then the cam elastic force that overcomes torsion spring and extension spring was transferred to the hard-over position.Moving beam continues descending, and then the top wheel contacts (Fig. 9) with the cam disengagement, and cam to original state, is waited for the execution of next action by elastic returning.
This device does not have to increase additional power source, utilized the lifting of moving beam to realize hovering and opening, and its normal lifting on moving beam do not affect fully, moving beam is the speed lifting of follow procedure setting fully, without any impact, easy to use and reliable on suspension device.When hovering, the halt regional extent is large, and operation and control are convenient.
