Embodiment

Below, with reference to accompanying drawing and embodiment, the utility model is described further：

As shown in figure 1, a kind of brake device of wheel, including Zhi Sha mechanisms 1, the mounting seat 2 of wheel 3 and it is articulated in wheel Wheel 3 in 3 mounting seats, the Zhi Sha mechanisms 1 are articulated in including being fixed on the support bar 4 of the mounting seat 2 of wheel 3, wherein one end Pedal 5 of only stopping, wherein one end on support bar 4 are articulated in the unblock pedal 6 of the other end of pedal 5 of only stopping, end and are articulated in U-shaped link 7 and two ends on support bar 4 are articulated in support bar 4 respectively and the elasticity of unblock pedal 6 stops piece 8 of stopping, the elasticity Piece 8 of only stopping is located at below the unblock pedal 6 and is formed with the binding face for being fitted with the wheel 3；The unblock pedal 6 It is formed with pedal position 61；Back-moving spring 9 is provided between the unblock pedal 6 and the support bar 4；The ring of the U-shaped link 7 Portion and the upper surface slide of the pedal 5 of only stopping coordinate, and are offered on the unblock pedal 6 for when the binding face is fitted in The ring portion being embedded in during the wheel 3 for U-shaped link 7 is so that the elasticity stops the stopper slot that piece 8 of stopping keeps fitting in the wheel 3 10。

In the case of without using car, stop pedal 5 of stopping towards the pressing of the direction of wheel 3, pedal 5 of only stopping overcomes back-moving spring 9 Elastic stress drive unblock pedal 6 and elasticity only piece 8 of stopping do downward circular motion, now, relative only stop of U-shaped link 7 is stepped on The slide downward of plate 5, when elastic piece 8 of only stopping, which is moved to, fits in wheel 3, the ring portion of U-shaped link 7 is fastened in stopper slot 10, Release is only stopped pedal 5, and pedal 5 of now only stopping is resisted against U by unlocking pedal 6 in the presence of the elastic stress of back-moving spring 9 Type link 7, now, support bar 4 produce power towards wheel 3 and then real to pedal 5 of only stopping by 7 pairs of pedals 5 of only stopping of U-shaped link Existing restriction effect, so that only stop pedal 5 and unblock pedal 6 are in poised state, now, brake block holding fits in described Elasticity stops stop piece 8, and then the rolling of limiting wheel 3；When needing to use car, towards the direction being unlocked by pressing pedal 6 of wheel 3, and to The upper U-shaped link 7 of lifting disengages it from stopper slot 10, and unblock pedal 6 drives under the elastic stress effect of back-moving spring 9 and only stopped Pedal 5 and elasticity piece 8 of only stopping are moved towards the direction away from wheel 3, and then car is affranchised state.

Stopped by support bar 4, only pedal 5, U-shaped link 7, stopper slot 10 and elasticity of the utility model is only stopped the cooperation of piece 8, Realize that elasticity is stopped into piece 8 of stopping is close to the rolling of wheel 3 and limiting wheel 3, and then prevent that article from colliding with outside, and it is logical The mating reaction of unblock pedal 6 and back-moving spring 9 is crossed, and then recovers the free state of wheel 3.

The pedal 5 of only stopping is outwardly formed close to one end of the support bar 4 is formed with a hook portion 51, prevents U-shaped link 7 The position away from pedal 5 of only stopping is turned to without being moved with pedal 5 of only stopping, and then avoids error.

In order to slow down the vibrations of jolting that car is produced in the road surface movement of out-of-flatness, the mounting seat 2 of wheel 3 includes peace Fill plate 21.It is fixed on installing plate 21 and the support arm 22 with side opening, middle part is articulated in the inner support 23 of support arm 22, institute The wherein side that wheel 3 is articulated in the inner support 23 is stated, the opposite side of the inner support 23 is inserted into by the side opening Snubber elastomeric part 11 is provided with the support arm 22, and between the bottom of the support arm 22 and the bottom of the inner support 23, it is described The two ends of snubber elastomeric part 11 are corresponded and are fixedly connected with the support arm 22 and the inner support 23, and 3 stress of wheel are passed Inner support 23 is handed to, then snubber elastomeric part 11 is transferred to support arm 22, passes through the cushioning effect of snubber elastomeric part 11, reduction vibrations Amplitude.

It is preferred that, the snubber elastomeric part 11 includes the buffer stopper 111 for being fixed on the inner support 23 and one end is fixed on Buffer spring 112 in buffer stopper 111, the other end of the buffer spring 112 is fixed on the support arm 22, and described slow Polyurethane blob of viscose can be used by rushing block 111.

In order to prevent support arm 22 from being overturn in the presence of snubber elastomeric part 11, in addition to gag lever post 12, the limit Position bar 12 is arranged in the support arm 22, and the formation of the gag lever post 12 has and touched for being offseted with the roof of inner support 23 Support meet, by gag lever post 12 limit inner support 23 rotational angle, and then avoid upset.

It is preferred that, the support arm 22 is arranged on the installing plate 21 by bearing, is realized 360 ° of rotations of car body, is made Car uses more flexible.

It is preferred that, the unblock pedal 6 is positioned at the lower section of pedal 5 of only stopping, and the pedal position 61 stretches out in described stop Stop outside pedal 5.

It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various It is corresponding to change and deformation, and all these change and deformation should all belong to the protection of the utility model claim Within the scope of.
