Nave boss 11.
It should be pointed out that bidirectional hydraulic oil cylinder 4 is the prior art, principle is referring to existing bidirectional hydraulic oil cylinder 4.Make
User can choose the bidirectional hydraulic oil cylinder 4 of different model and specification according to the actual situation.
In the present embodiment, pull rod cam 6 and adjusting nut 16 are located at the both ends of sliding axle 14, and 6, pull rod cam
In the side far from the second brake shoes 13 of first brake shoe plate 12, pull rod cam 6 is rotatably connect simultaneously with sliding axle 14
First brake shoe plate 12, pull rod cam 6 and 16 collective effect of adjusting nut is resisted against to brake in first brake shoe plate 12 and second
Shoe plate 13, to limit the spacing of first brake shoe plate 12 and the second brake shoes 13.
Specifically, one end of pull rod 61 and piston rod 41 are cut with scissors as shown in Fig. 2, pull rod cam 6 includes pull rod 61 and cam 62
It connects, the other end of pull rod 61 is fixedly connected with cam 62.Cam 62 offers the open slot 63 worn for sliding axle 14, sliding axle
One end of 14 separate adjusting nut 16 is arranged in open slot 63, the separate pull rod 61 of the opening of open slot 63 towards cam 62
Direction.Cam 62 offers the mounting hole being connected to open slot 63, and the rotation cooperated with sliding axle 14 is equipped in mounting hole
Pin shaft 64, rotating pin 64 are rotatably connect with sliding axle 14, when cam 62 is rotated relative to sliding axle 14, cam 62
Edge contour presses on first brake shoe plate 12, with the transformation of the edge contour of cam 62, first brake shoe plate 12 and second
Spacing between brake shoes 13 reduces, to hold brake hubs 11 tightly.
Further, one end of rotating pin 64 offers pin hole, and split pin 65 is inserted in pin hole, and split pin 65 is used for
Rotating pin 64 is limited along the axial movement of mounting hole.It should be noted that one end setting of the separate pin hole of rotating pin 64
There is limiting stand, rotating pin 64 can only be worn by the one end for offering pin hole into mounting hole, and split pin 65 and limiting stand are matched
Cooperation is used, and the axial movement of rotating pin 64 is limited.
In the present embodiment, cam 62 is obliquely installed with pull rod 61, and there is the edge contour of cam 62 abutment (to work as cam
62 when turning to the extreme position of first brake shoe plate 12, the point that cam 62 and first brake shoe plate 12 abut against), abutment arrives
The distance of the centre of gyration of cam 62 is adjustment distance, and the distance of other point to the centres of gyration of the edge contour of cam 62 is less than
Adjust distance, it is understood that be that abutment is the farthest point of the edge contour of cam 62.The line of the centre of gyration and abutment
Angle between the center line of pull rod 61 is 120 ° -150 °, is equivalent to, the tilt angle of cam 62 and pull rod 61 is 120 ° -
150°.When cam 62 and pull rod 61 are obliquely installed, for pull rod cam 6 relative in 14 rotation process of sliding axle, cam 62 can
It is mobile towards the second brake shoes 13 to compress first brake shoe plate 12, in such cases, the stroke of first brake shoe plate 12 is larger,
And it is easy to control, driving force used is smaller.Inventor through a large number of experiments the study found that when tilt angle be chosen for 120 °-
At 150 °, both it is convenient for the rotation of pull rod cam 6, brake torque is big, and braking time is short, also facilitates the shifting of first brake shoe plate 12
It is dynamic, it is lower to the driving force request of bidirectional hydraulic oil cylinder 4, it brakes more flexible.
Further, for the ease of the holding of realization brake hubs 11, in first brake shoe plate 12 and the second brake shoes 13
