Detailed Description
The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1:
referring to the attached drawings 1-4 in the specification, the disc brake for the new energy automobile in the embodiment includes a brake main body 1, a hub installation component 2 is arranged at one end of the brake main body 1, a first brake friction plate 3 is fixedly installed at one end of the hub installation component 2, a second brake friction plate 4 is fixedly installed on the first brake friction plate 3, and a brake system 5 is fixedly installed on the second brake friction plate 4, so that friction assistance is generally avoided, and the brake performance is less affected by a friction coefficient, i.e., the performance is more stable; the efficiency is reduced less after soaking, and the brake can be recovered to normal only by once or twice braking; under the condition of the same output braking torque, the size and the mass are generally smaller; the thermal expansion of the brake disc in the thickness direction is extremely small, and the brake pedal stroke is not too large due to the obvious increase of the brake clearance like the thermal expansion of the brake drum.
Furthermore, a large nut 21 is fixedly installed in the middle of the hub installation component 2, screws 22 are fixedly installed on the periphery of the hub installation component 2, the large nut is connected with a bearing of a wheel and has the purpose of stabilizing a brake, and the screws on the periphery are connected with screw holes of the wheel and increase the stability of the brake.
Further, brake friction disc 3 middle-end is equipped with big screw 31, and big screw 31 periphery is equipped with little screw 32, brake friction disc 3 is equipped with louvre 33, louvre 33 layout mode sets up to the scattering formula, louvre 33 one side is equipped with radiating groove 34, and thermal stability is better, because the size of brake friction lining piece is not long, and its working surface's area only is 12% ~ 6% of brake disc area, louvre evenly distributed, and the louvre through the scattering formula distributes, can accord with the direction of motion of air current, helps giving off of hot gas, increases its heat dispersion.
Furthermore, the second brake friction plate 4 and the first brake friction plate 3 are identical in structure, the upper end of the second brake friction plate 4 is provided with an adjusting screw 41, the position of the second brake friction plate 4 is adjusted through the adjusting screw, and a disc type friction lining is easier to replace than a drum type friction lining after being worn.
Furthermore, an oil filling port 51 is formed in one end of the braking system 5, the oil filling port 51 is movably connected with a piston system 52, the piston system 52 is fixedly connected with calipers 53, and water stability is good. Because the brake lining block is high in unit pressure to the disc, water is easily extruded out, the brake lining block is easy to throw away after being stained with water under the action of centrifugal force, and the brake lining block has a wiping effect on the disc, so that the brake lining block can be recovered to be normal after water is discharged only through primary braking and secondary braking, and the brake effect is effectively improved by taking the piston hydraulic pressure as power.
Furthermore, a brake pad 521 is arranged at one end of the piston system 52, a piston 522 is fixedly installed at one end of the brake pad 521, and a gap between a brake disc and a friction pad is small (0.05-0.15 mm), so that the operation time of the oil cylinder piston is shortened, the force transmission ratio of the brake driving mechanism is increased, and the transmission efficiency is increased.
The implementation scenario is specifically as follows: use the utility model discloses the time by technical personnel in the field install this equipment in the car, fluid from oiling mouth 51 by the pressure in inside and outside two wheel cylinders, its piston compresses tightly the brake disc with two brake blocks under the hydraulic pressure effect, produces friction torque and braking, at this moment, the edge of the rectangle rubber seal circle in the wheel cylinder groove produces micro elastic deformation under the effect of piston 522 frictional force, when relaxing the braking, piston 522 and brake block rely on the elasticity of sealing washer and the elasticity return of spring. Because the deformation of the edge of the rectangular sealing ring is very small, when the brake is not performed, the clearance between the friction plate and the disc is only about 0.1mm on each side, and the brake can be released sufficiently. When the brake disk is heated and expanded, the thickness of the brake disk is slightly changed, so that the phenomenon of 'support stagnation' cannot occur, and the rectangular rubber sealing ring has the functions of sealing, piston return and automatic clearance adjustment.
Example 2:
referring to the attached FIG. 5 of the specification, the difference from the embodiment 1 is: the heat dissipation holes 33 are also arranged in a surrounding manner, and the heat dissipation groove 34 is arranged on one side of the heat dissipation holes 33. The radiating holes arranged in a surrounding mode are used, the brake friction plate 3 can be arranged according to the shape of the brake friction plate, the influence of air flow on the brake friction plate is reduced, and the strength of the brake friction plate 3 can be improved.
The implementation scenario is specifically as follows: use the utility model discloses the time by technical personnel in the field install this equipment in the car, fluid from oiling mouth 51 by the pressure in inside and outside two wheel cylinders, its piston compresses tightly the brake disc with two brake blocks under the hydraulic pressure effect, produces friction torque and braking, at this moment, the edge of the rectangle rubber seal circle in the wheel cylinder groove produces micro elastic deformation under the effect of piston 522 frictional force, when relaxing the braking, piston 522 and brake block rely on the elasticity of sealing washer and the elasticity return of spring. Because the deformation of the edge of the rectangular sealing ring is very small, when the brake is not performed, the clearance between the friction plate and the disc is only about 0.1mm on each side, and the brake can be released sufficiently. When the brake disk is heated and expanded, the thickness of the brake disk is slightly changed, so that the phenomenon of 'support stagnation' cannot occur, and the rectangular rubber sealing ring has the functions of sealing, piston return and automatic clearance adjustment.
