Abstract
The utility model relates to an expanding brake structure, concretely to a slave drive assembly in the expanding brake structure. The utility model is characterized in that an improved structure of brake slave drive assembly comprises a follower which is threaded through the slave drive hole of the brake shell, a rolling columniation is provided between the follower and the slave drive hole of the brake shell. Because of the rolling columniation being arranging between the contact face of the rolling columniation and the brake shell, friction decreases and the integrated service life of the slave drive assembly and the expanding brake is prolonged.
Description
Technical field
The utility model relates to the structure of stopping that expands, and is specifically related to the servo-actuated assembly in the bloated structure of stopping.
Background technique
Brake is a key of guaranteeing traffic safety, also is one of parts that frequency of utilization is the highest in the driving.The servo-actuated that provides is in the market stopped, because its good braking quality, noise free is well received by consumers.In servo-actuated was stopped, whether the work of servo-actuated assembly well was the key of guaranteeing quality of product.The servo-actuated that provides is in the market stopped because existing problems are gone up in its design: the work of servo-actuated post is side-to-side movement in the servo-actuated hole of brake shell.When brake, the left hoof block length phase is subjected to the effect of power upwards, and the servo-actuated post just and the friction of brake shell causes rubbing of the abrasion of brake shell and servo-actuated post flat, thereby increased both surface of contact.Cause the servo-actuated assembly can not work and the inefficacy of right hoof piece at last, have a strong impact on the working life of braking effect and brake.
Summary of the invention
The purpose of this utility model is to provide a kind of friction that reduces between servo-actuated post and the brake shell, improves the brake servo-actuated assembly structure-improved in the bloated structure of stopping of stopping working life that expands.
To achieve these goals, the utility model adopts following technological scheme: a kind of brake servo-actuated assembly structure-improved, comprise the servo-actuated post, and the servo-actuated post passes the servo-actuated hole of brake shell, also is provided with the rolling post between the servo-actuated hole of described servo-actuated post and brake shell.Install the rolling post additional by centre, make its friction mode become rolling friction, thereby reduce friction, the whole service life that improves the servo-actuated assembly and expand and stop by sliding friction at the servo-actuated post and the surface of contact of brake shell.
As preferably, the height of described rolling post is less than the thickness of brake shell.
The utility model is provided with the rolling post that matches with both owing to adopt technique scheme between the servo-actuated hole by servo-actuated post and brake shell.Install the rolling post additional by centre, make its friction mode become rolling friction, thereby reduce friction, the whole service life that improves the servo-actuated assembly and expand and stop by sliding friction at the servo-actuated post and the surface of contact of brake shell.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a parts drawing of the present utility model;
Fig. 3 is a kind of structural representation that expands and stop of the present utility model;
Fig. 4 is the schematic representation in the servo-actuated hole on the brake shell of the present utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is further described by specific embodiment.
As depicted in figs. 1 and 2, the servo-actuated post 4 in the servo-actuated assembly of the present utility model is divided into up and down two-part, and the upper end of servo-actuated post 4 connects right hoof piece 3 and left hoof piece 2 successively, links together by nut 10 and servo-actuated post 4 after filling up the lastblock pad on the left hoof piece 2 again.The servo-actuated hole 14 of brake shell 6 is passed in the lower end of servo-actuated post 4, as shown in Figure 4, link together with corresponding servo-actuated bowl 7, nut 8 and nut cap 9, add rolling post 5 in the centre of the servo-actuated post 4 and the surface of contact of brake shell 6, the height of rolling post 5 is less than the thickness of brake shell.
As shown in Figure 3 and Figure 4, when brake, curved bar 11 drives eccentric wheel 12 motions, and then makes that servo-actuated assembly 13 is in running order.At this moment, left side hoof piece 2 is subjected to the effect of upward force, servo-actuated post 4 side-to-side movement in the servo-actuated hole 14 of brake shell 6, because between has installed rolling post 5 additional, make its friction mode become rolling friction by sliding friction, reduce the abrasion of friction and brake shell 6, made left hoof piece 2 and right hoof piece 3 be in good working order for a long time, improved the working life of servo-actuated assembly 13 and the whole bloated structure of stopping.
Claims (2)
1, a kind of brake servo-actuated assembly structure-improved comprises servo-actuated post (4), and the servo-actuated hole (14) of brake shell is passed in the lower end of servo-actuated post, it is characterized in that: also be provided with rolling post (5) between the servo-actuated hole (14) of described servo-actuated post and brake shell.
2, brake servo-actuated assembly structure-improved according to claim 1 is characterized in that the thickness of the height of described rolling post (5) less than brake shell (6).
