Abstract
The utility model provides a multi-cylinder brake caliper, which belongs to the technical field of machinery and solves the problem that an existing brake caliper is unstable. The multi-cylinder brake caliper comprises a caliper body with a jaw, at least four piston cavities in even number are symmetrically arranged on two inner sides of the jaw, a piston is arranged in each piston cavity, the caliper body is provided with an oil inlet and an oil passage for communicating the oil inlet with the piston cavities, and the piston cavities are symmetrically arranged in pairs by centering on the jaw. The multi-cylinder brake caliper is simple in structure and high in use stability.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of brake calipers, particularly a kind of multi-cylinder braking tongs.
Background technique
Existing hydraulic braking pincers generally comprise caliper, braking plate, piston, and piston promotes braking plate and abuts on the brake disc to realize braking.In high performance vehicle, in brake calipers, often adopt opposed two pistons to promote braking plate respectively traditionally.Braking plate is connected with piston.
In the time of braking, piston stretches out realizes braking.Behind brake off, braking plate is return with piston.Usually, existing brake calipers only has two symmetrically arranged pistons, and braking force is not steady when realizing braking, and insensitivity is relatively poor.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist at prior art, provides a kind of simple in structure, the multi-cylinder braking tongs that practical Stability is high.
The purpose of this utility model can realize by following technical proposal: a kind of multi-cylinder braking tongs, comprise caliper with jaw, the inboard symmetry of jaw two be provided with piston cavity, be provided with piston in the piston cavity, the oily passage of mistake that has filler opening on the described caliper and filler opening is communicated with piston cavity, it is characterized in that, have at least four even number piston cavity in the described caliper, and piston cavity is symmetrical arranged in twos with the jaw center.
Have the common hydraulic system that driven plunger moves around in piston cavity in this multi-cylinder braking tongs, hydraulic system is: oil hydraulic pump and the filler opening that links to each other with oil hydraulic pump, the oily passage of mistake.Braking plate is installed on the piston, and after piston promotion braking plate moved, the hydraulic braking pincers were realized braking; After piston was return, braking plate was along with returning.
In above-mentioned multi-cylinder braking tongs, the piston cavity chamber place of the oil outlet of the oily passage of described mistake between piston the inner and piston cavity.
The fluid that makes filler opening feed like this can enter each piston cavity place smoothly.
In above-mentioned multi-cylinder braking tongs, be provided with seal ring between described piston and the piston cavity.
By the seal ring sealing good to realization between piston and the piston cavity.
In above-mentioned multi-cylinder braking tongs, the oily passage of described mistake has the oil outlet identical with piston cavity quantity.
Such structure makes fluid to be entered in each piston cavity by oil outlet smoothly.
In above-mentioned multi-cylinder braking tongs, has dustproof collar between described piston outer end and the piston cavity port.
Make impurity such as dust can't enter between piston and the piston cavity by dustproof collar.
Compared with prior art, this multi-cylinder braking tongs is owing to have four pistons, and four pistons move simultaneously when braking, makes the braking plate stress equalization, and therefore, its stability in use is than higher.
Simultaneously, this multi-cylinder braking tongs has just increased the quantity of piston cavity and piston, and therefore, it relatively simple for structure has advantages of high practicability.
Description of drawings
Fig. 1 is the structural representation of this multi-cylinder braking tongs.
Fig. 2 is the sectional structure schematic representation of this multi-cylinder braking tongs.
Fig. 3 is the broken section structural representation at piston and piston cavity place in this multi-cylinder braking tongs.
Among the figure, 1, caliper; 1a, jaw; 1b, piston cavity; 2, filler opening; 3, cross oily passage; 4, piston; 5, seal ring; 6, dustproof collar.
Embodiment
As shown in Figure 1, this multi-cylinder braking tongs comprises the caliper 1 with jaw 1a, the inboard symmetry of jaw 1a two be provided with piston cavity 1b, be provided with piston 4 in the piston cavity 1b, on the piston 4 braking plate can be installed.
As shown in Figures 2 and 3, have filler opening 2 on the caliper 1 and cross oily passage 3, cross oily passage 3 filler opening 2 is communicated with piston cavity 1b.In the present embodiment, the piston cavity 1b cavity place of the oil outlet of the oily passage 3 of mistake between piston 4 the inners and piston cavity 1b, and oily passage 3 has and the identical oil outlet of piston cavity 4 quantity excessively.
The piston cavity 1b that has four in the caliper 1, and piston cavity 1b is that the center is symmetrical arranged in twos with jaw 1a, all has a piston 4 in each piston cavity 1b.
During work, fluid through filler opening 2, cross oily passage 3 and enter in four piston cavity 1b, braking plate is positioned on the exterior edge face of piston 4, after four pistons 4 promoted the braking plates action, the hydraulic braking pincers were realized braking; After piston 4 was return, braking plate was eliminated braking along with returning.
In addition, between piston 4 and piston cavity 1b, be provided with seal ring 5, between piston 4 outer ends and piston cavity 1b port, have dustproof collar 6.Seal ring 5 its to seal action, dustproof collar 6 can prevent that impurity such as dust from entering.
