The invention relates to an automobile skid device, in particular to an automobile ring-shaped brake. The ring-shaped brake comprises a brake bottom plate (3) and friction plates (2) and is characterized in that the brake bottom plate (3) is fixed with a plurality of piston oil cylinder components (5) which are provided inside with seal spring components (8); the outer end of a telescopic link (81) of each the seal spring component (8) is fixed with the friction plate (2); each two of the piston oil cylinder components (5) are connected through an oil pipe connected with a nut (15) and a sealed ring-shaped oil pipe (14); a return spring (18) is arranged on the brake bottom plate (3) and the friction plates (2). The invention can prevent the locking of a brake drum, thereby strengthening the automobile stopping power; when braking, the automobile does not have the phenomena of off tracking and sideslip with shortened braking distance and improved braking safety of the automobile.
Description
Technical field:
The present invention relates to a kind of brake device for car.
Background technique:
Traditional automotive friction type drum brake is mainly based on wheel cylinder brake and cam type brake, but all because the area of contact instability between the hoof drum, the different excursions of material, temperature, surface condition with brake drum and friction plate increase, and the surface of contact of friction plate and drum is little, causes braking effect to reduce.Though kind is a lot, complex structure, materials are many, the phenomenon that causes the low automobile brake sideslip of Braking efficiency to break away.Abs braking mode not only price is high, and its effect of portioned product also has deficiency.
The Chinese patent 01269451.7 of inventor's application, a kind of annular piston formula break is disclosed, it includes braking bottom board, piston, brake slipper, return spring, at braking bottom board cylindrical distribute some brake slipper, the corresponding brake slipper of each piston, brake slipper is connected with return spring with the braking bottom board inner panel, and oil pipe and piston are connected components.This break has the following disadvantages:
1) return spring forms potential safety hazard owing to be easy to fall into brake drum after the wearing and tearing.
2) pressure spring unrestricted motion meeting worn piston cylinder body in piston makes the seals damaged leakage of oil, makes automobile lose braking.
Summary of the invention:
The objective of the invention is to avoid the deficiencies in the prior art part and a kind of Vehicular ring-shaped brake is provided, it has good braking effect, safety, and long service life, materials being fabricated is made more convenient less, can effectively solve phenomenons such as automobile brake locking, sideslip, sideslip.
Another object of the present invention is sealed in pressure spring in the spring assembly sealed cylinder block, makes pressure spring not store part energy before the braking, can discharge and absorb the excess energy from oil circuit when braking.
Of the present invention also have a purpose that return spring is compressed, and makes after braking is removed and can better make the friction plate return.
Purpose of the present invention can be by realizing by the following technical solutions: a kind of Vehicular ring-shaped brake, include braking bottom board (3), friction plate (2), its main feature is to be fixed with several piston oil-cylinder assemblies (5) on braking bottom board (3), in piston oil-cylinder assembly (5), be provided with Packing spring assembly (8), flexible rod (81) outer end of Packing spring assembly (8) friction plate (2) that is connected; Piston oil-cylinder assembly (5) is connected piston oil-cylinder assembly (5) with the fuel ring pipe (14) of sealing in twos by oil pipe attaching nut (15); On braking bottom board (3) and friction plate (2), also be provided with return spring (18).Make the friction plate that stretches out be returned to the origin-location later at automobile brake.
Piston oil-cylinder assembly (5) is connected with the fuel ring pipe (14) of sealing by oil pipe attaching nut (15) in twos, formed the closed ring oil circuit, brake oil enters under the situation of pressure is arranged and produces the hydrodynamic pressure Sasser in the annular oil circuit, the Sasser stack that Packing spring assembly in this pressure oscillations ripple and the piston produces at the volley, the Packing spring assembly mainly is meant dish spring (82), flexible rod (81), retainer (85), spring assembly sealing cylinder (84), its effect are friction plates: " holding--loosening--tightly holds tightly " not locking when making automobile brake.
Described Vehicular ring-shaped brake, be described Packing spring assembly (8) be in oil cylinder (51), piston (52) top is provided with dish spring (82), dish spring (82) top is provided with flexible rod (81), in spring assembly sealing cylinder (84), flexible rod (81) is provided with directional post (83) and embeds in the guiding groove that is located on the piston (52), is provided with retainer (85) between flexible rod (81) and the spring assembly sealing cylinder (84).
Described piston oil-cylinder assembly (5) is provided with preloading spring (53) in the below of piston (52); Piston oil-cylinder assembly (5) also is provided with dust-proof cover (54) on spring assembly (8).
Described piston oil-cylinder assembly (5) and the corresponding one by one setting of friction plate (2), it is 2-20 that quantity is set.The friction plate that wholecircle week distributes improves the braking useful area and improved retardation efficiency when braking, symmetry was stressed when the brake slipper of symmetry reached braking when solving braking not sideslip, the purpose of not breakking away.It is 2-20 that quantity is set, and is preferably even number, uses equilibrium of forces in the time of can making automobile brake like this, and heat produces less.
Described Vehicular ring-shaped brake is provided with filler opening (4) and exhaust nozzle (6) on described piston oil-cylinder assembly (5).
Described Vehicular ring-shaped brake also includes in braking bottom board (3) outside and also is provided with mudguard wing (1).
Described Vehicular ring-shaped brake is provided with seal ring (71) on the cylinder wall of described oil cylinder (51); Between described oil cylinder (51) and piston (52), be provided with seal ring (72); Between cylinder pedestal (55) and piston (52), also be provided with seal ring (73).This is when split production of the present invention, the seal ring that is provided with.
The invention has the beneficial effects as follows: prevent the locking of brake drum, the automobile brake ability strengthened, during braking automobile not sideslip, do not break away, and reduced stopping distance, improved automobile braking safety.Below its effect is described with one group of contrast experiment.
