The working principle of this machinery brake assembly is through pull bar, to order about friction plate 22 and produce with brake disc 1 object that friction reaches braking by foot treadle is stressed, tricycle braking device assembly shown in Fig. 1, comprise brake disc 1, a pair of brake shoe assembly 2 is arranged on the front of brake disc 1 relatively.Brake axle 5 front ends are kidney-shaped axostylus axostyle, and the lower end of brake shoe 21 is provided with positioning plate, and two positioning plates are arranged on the both sides of kidney-shaped axostylus axostyle relatively, and conventionally, the Extreme breadth of kidney-shaped axostylus axostyle is W
1, minimum width is W
2, and W
1=2W
2.During initial perfect condition, friction plate 22 is 0.3～0.6mm with the gap of brake disc 1, and period of braking is short, highly sensitive; In use, friction plate 22 constantly weares and teares, brake axle 5 starts to rotate to gradually level by vertical state, brake axle 5 promotes brake shoe 21 and outwards and around brake pin 4 rotates, thereby the wearing and tearing to friction plate 22 compensate, guarantee that friction plate 22 contacts all the time generation friction and brakes with brake disc 1.When brake axle 5 rotates to level, as shown in Figure 2, now friction plate 22 has been used to ultimate state, but friction plate 22 still remains and has very large thickness, and friction plate 22 cannot compensate for wear, can cause very large waste on the one hand, cause on the other hand while braking and brake disc excesssive gap, braking moment lengthens, thereby cause braking insensitive, period of braking, extend, parking immediately while having accident and accidents caused, while being embodied in especially long descending loading, braking moment and sensitivity are required higher, because of braking, cause not in time traffic accident.
Model utility content
The utility model aims to provide a kind of adjustable brake assembly that is applicable to tricycle, the wearing and tearing of friction compensation sheet to greatest extent, in the wearing and tearing middle and later periods, still can accurately control the optimum state that brake clearance remains on 0.3～0.6mm, extend the working life of friction plate, avoid waste.
For this reason, the technological scheme that the utility model adopts is: a kind of adjustable brake assembly that is applicable to tricycle, comprise brake disc (1), a pair of brake shoe assembly (2) is arranged on the front of brake disc (1) relatively, and extension spring (3) is housed between two brake shoe assemblies (2), the top at described brake disc (1) back side is welded with two brake guidees (1a) that are symmetrically arranged, in each brake guide (1a), a brake pin (4) is housed, the place, middle position, bottom at brake disc (1) back side is welded with a brake axle sleeve (1b), a brake axle (5) is housed in described brake axle sleeve (1b), described brake shoe assembly (2) comprises brake shoe (21) and sticks on the friction plate (22) of brake shoe (21) outer wall, the upper end of described 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 plates (21b) are arranged on kidney-shaped axostylus axostyle (5a) both sides of brake axle (5) front end relatively, it is characterized in that: the Extreme breadth of described kidney-shaped axostylus axostyle (5a) is W
1, minimum width is W
2, and W
1-2W
2>=4mm.
The beneficial effects of the utility model are: by increasing the Extreme breadth of kidney-shaped axostylus axostyle, maximally utilised friction plate, extended the working life of friction plate, realized and having made the best use of everything: improved sensitivity, guarantee the brake clearance of the optimum state, avoid running into accident or parking immediately and cause traffic accident when long descending loading state.
