Problems solved by technology

[0004] 1) The return spring is easy to fall into the brake drum due to wear, causing a safety hazard
[0005] 2) The free movement of the compression spring in the piston will wear the piston cylinder, damage the seal and leak oil, and cause the car to lose its brakes

Embodiment 1

[0050] Example 1, see figure 1 , figure 2 , image 3 , a kind of annular brake for vehicles, including a brake base plate 3, a friction plate 2, four piston cylinder assemblies 5 are fixedly connected on the brake base plate 3, a seal spring assembly 8 is arranged in the piston cylinder assembly 5, and the seal spring The outer end of the telescopic rod 81 of the assembly 8 is fixedly connected with the friction plate 2; the piston cylinder assembly 5 is connected with the sealed annular oil pipe 14 through the oil pipe connecting nut 15; the brake base plate 3 and the friction plate 2 are also connected Return spring 18 is provided. The sealing spring assembly mainly refers to the disc spring 82, the telescopic rod 81, the lock ring 85, and the sealing cylinder 84 of the spring assembly. No locking when braking. The sealing spring assembly 8 is provided with a disc spring 82 above the piston 52 in the oil cylinder 51, and a telescopic rod 81 is provided above the disc sp...

Embodiment 2

[0051] Example 2, see Figure 4 , the same as in Embodiment 1, the number of piston cylinder assemblies 5 is 12.

[0052] When the automobile brakes, the brake oil enters the oil inlet 4 of the piston cylinder assembly 5 under the pressure of the automobile brake master cylinder, enters the piston cylinder assembly 5, and passes the piston 52 in the piston assembly through the inner hole of the piston cylinder assembly. Push out, the piston 52 pushes the sealing spring assembly 8 again, and the sealing spring assembly 8 pushes out the friction plate 2 again, and the friction plate 2 contacts with the brake drum to realize braking. When the brake is released, the friction plate 2 is under the pressure of the return spring 18 The back pressure seal spring assembly 8 seal spring assembly 8 presses the piston 52 again, and the piston (52) presses the brake oil back to the brake master cylinder through the oil inlet (4) to complete braking. Wherein the effect of exhaust nozzle (6)...

Abstract

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: [0001] The invention relates to an automobile braking device. Background technique: [0002] Traditional automobile friction drum brakes are mainly wheel-cylinder brakes and cam brakes, but because the contact area between the hoof and the drum is unstable, the material, temperature, and surface condition of the brake drum and the friction plate are different. The range of variation increases, and the contact surface between the friction plate and the drum is small, resulting in reduced braking effect. Although there are many types, the structure is complex and the materials used are many, which leads to the phenomenon that the braking efficiency of the automobile is low, and the vehicle brakes and runs sideways. The ABS braking method is not only expensive, but the effect of some products is also insufficient. [0003] The Chinese patent 01269451.7 applied by the inventor discloses a ring-shaped piston brake, which includes a brake base plate, a piston, a...
