Abstract
The utility model provides a dual face truckle of synchronous brake that comprises a truckle body and a brake device; wherein, the brake device includes a cam, a pushing rod, a spring and a spring sleeve as well as a brake block; one end of the brake block is close to the center of the truckle edge, while the other end is connected with one end of the pushing rod; the other end of the pushing rod is through the spring sleeve and the spring inside and in contact with the truckle edge. Each truckle cam is easy to be connected with the brake device, thus each truckle can realize synchronous brake and the problem of unstable frame caused by asynchronous brake is avoided. Besides, the utility model has the advantages of simple structure and easy implementation.
Description
Technical field
The utility model relates to a kind of castor, and the spy relates to a kind of two-sided castor that is used for synchronous braking.
Background technology
Its brake gear of the caster wheel of like product employing at present is arranged on the brake pedal on each castor, steps on this pedal and this castor can be checked.General go-cart needs four castors in application, and the shortcoming of this castor is only can cause the car body skew to a castor brake simultaneously with all castor synchronous brakes, and stability is bad.
Summary of the invention
The utility model purpose just provides a kind of two-sided castor that can be used in synchronous braking.
For achieving the above object, the utility model is taked following technical scheme: comprise wheel body and stop mechanism, described stop mechanism comprises cam, push rod, spring and overcoat thereof, brake shoes, one end of brake shoes is close in the middle of the wheel body outer rim, its other end is connected with push rod one end, the other end of this push rod passes spring overcoat and interior spring thereof, and contacts with the cam outer rim.
An end that contacts with cam at described push rod has the roller dish, in the groove in the end face roller is arranged thereon, and this roller and described cam are coaxial.
The utility model has the advantages that: the cam of each castor is easy to be connected with link gear, make each castor can realize synchronous braking, has eliminated because the car body wild effect that can not synchronous brake causes.It is simple in structure, implements easily.
Description of drawings
Further specify below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, novel wheel body 1 and the stop mechanism of comprising of this reality, this stop mechanism comprises cam 8, push rod 3, spring 5 and overcoat 4 thereof and brake shoes 2, one end of brake shoes 2 is close in the middle of wheel body 1 outer rim, leaves braking gap 9 between the two, and its other end is connected with an end of push rod 3, the other end of this push rod 3 passes spring overcoat 4 and interior spring 5 thereof, and be connected with roller dish 6 one ends, a roller 7 is arranged in the groove in the upper surface of this roller dish 6, this roller 7 is axially identical with described cam 8.
Claims (2)
1, a kind of two-sided castor that is used for synchronous braking, comprise wheel body and stop mechanism, it is characterized in that: described stop mechanism comprises cam, push rod, spring and overcoat thereof, brake shoes, one end of brake shoes is close in the middle of the wheel body outer rim, its other end is connected with push rod one end, the other end of this push rod passes spring overcoat and interior spring thereof, and contacts with the cam outer rim.
2, the two-sided castor that is used for synchronous braking according to claim 1, it is characterized in that: an end that contacts with cam at described push rod has the roller dish, in the groove in the end face roller is arranged thereon, and this roller and described cam are coaxial.
