Embodiment
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
In conjunction with Fig. 3---shown in Fig. 5, a kind of machinery adjustable brake assembly of stopping, entirety is symmetrical structure, is made up of brake disc 1, a pair of brake shoe assembly 2, extension spring 3, brake pin 4, brake axle 5, tuning drive gear steel disc 6, nut 7, spacing jump ring 8 etc.
A pair of brake shoe assembly 2 is arranged on the front of brake disc 1 relatively, and between two brake shoe assemblies 2, extension spring 3 is housed, the top at brake disc 1 back side is welded with two brake guide 1a that are symmetrically arranged, a brake pin 4 is housed in each brake guide 1a, middle position, the bottom place at brake disc 1 back side is welded with a brake axle sleeve 1b, in brake axle sleeve 1b, a brake axle 5 is housed.Brake shoe assembly 2 is made up of brake shoe 21 and friction plate 22 grades that stick on brake shoe 21 outer walls, the upper end of brake shoe 21 is provided with central sleeve 21a, lower end is provided with positioning plate 21b, two central sleeve 21a are sleeved on each self-corresponding brake pin 4, two positioning plate 21b are arranged on the kidney-shaped axostylus axostyle 5a both sides of brake axle 5 front ends relatively, the above is same as the prior art, does not repeat them here.
Difference is: shown in Fig. 4, Fig. 6, brake pin 4 comprises the first axostylus axostyle 4a, the second axostylus axostyle 4b and the flat side 4c that are connected successively from front to back, the axis of relative the second axostylus axostyle 4b of axis of the first axostylus axostyle 4a offsets downward distance for e, and e > 0mm, the axis of the second axostylus axostyle 4b overlaps with the center line of flat side 4c, the first axostylus axostyle 4a coordinates with the central sleeve 21a of brake shoe 21, the second axostylus axostyle 4b coordinates with brake guide 1a, flat side 4c reaches outside brake axle sleeve 1b, is set with tuning drive gear steel disc 6 and locks by nut 7 on flat side 4c.Shown in Fig. 5, Fig. 7, tuning drive gear steel disc 6 middle parts have the square opening 6a with flat side 4c outline, and the local outwardly convex of periphery of tuning drive gear steel disc 6 forms pointer.Tuning drive gear steel disc 6 rotates with brake pin 4, and the upper end face periphery near tuning drive gear steel disc 6 of brake axle sleeve 1b is provided with graduation line 1c.
Preferably, the Extreme breadth of kidney-shaped axostylus axostyle 5a is W 1, minimum width is W 2, and W 1> 2W 2.Offset distance e is 2～4mm, W 1-2W 2=3～4mm.And in traditional braking hoof assembly, the Extreme breadth of brake axle middle part of the side oblique crank Z bar is generally the twice of minimum width.The front end of brake pin 4, the rear end of brake axle 5 are respectively set with a spacing jump ring 8, and the pin 4 that prevents from braking, brake axle 5 are deviate from.
Be that friction plate 22 use are to the state of bias, the extremely width position of brake axle 5 rotation of the limit, brake pin 4, owing to having increased the Extreme breadth W of kidney-shaped axostylus axostyle 5a in conjunction with Fig. 8 1, friction plate 22 is the near 1.89mm of thickness of thin position, and thinner with the thickness 2.91mm extremely prescribing a time limit than friction plate in traditional braking hoof assembly, be improved the working life of friction plate 22.Now, the brake axle 4 that is positioned at left side turns clockwise, and the brake axle 4 on right side is rotated counterclockwise, a graduation line 1c on each rotating scale pointer steel disc 6, when spin brake axle 4 is during to 45 ° of states as shown in Figure 9, the friction plate 22 near 0.95mm of thickness of thin position; Continue two brake axles 4 of rotation, in the time that brake axle 4 rotates to 90 ° of states, friction plate 22 utilizes completely, can ensure 10,000 kilometers of left and right of the many operations of vehicle.
In the time that reality is used, 3000 kilometers of left and right of the every operation of vehicle need brake axle 4 to do once rotation direction adjustment as shown in the figure.Friction plate 22 uses after wearing and tearing by brake axle 4 compensate for wear values, and using the pointer of tuning drive gear steel disc 6 as adjusting mark, every rotation one scale friction plate 22 compensates 0.23mm.When adjusting, the flat side 4c of spin brake pin 4 is to continuing rotation, make friction plate 22 be close to brake disc 1, opposite spin 2～4 scale tightening nuts 7 can complete Primary regulation again, now just in time ensure that friction plate 22 and the best clearance of brake disc 1 are 0.3～0.6mm, friction plate makes full use of, and meets the final usage requirement of product.
