Abstract
The utility model discloses a self-energizing disc brake, by the backup pad, support frame, pin, outer hoof, shell fragment etc. constitute. It can be used for motor vehicles such as cars, motorcycles, trucks and the like. Its main technical feature is that the self-boosting is generated by means of the inertia of car to implement boosting brake. Such a boost can also be used for braking other motor-driven bodies. The main technical problem is to select the proper angle between the rotor and the supporting plate and the gap between the inner shoe and the rotor. In a free state, when the clearance between the inner shoe and the rotor is 0.2-0.3mm, the angle between the rotor and the supporting plate is A95-105 degrees, so that sufficient self-energizing force is ensured.
Description
The utility model belongs to the self-propelled vehicle brake field.
Can be to understanding of the present utility model with reference to the plate disc brake on the existing small passenger car.
The purpose of this utility model is the inertia that utilizes in the motor-driven vehicle going, produces enough self energizing efforts by means of inertia on plate disc brake, carry out booster brake, and the speed of self-propelled vehicle is fast more, and the self energizing effort of generation is big more, and braking force is big more.In other words, under people's manipulation, utilize the implementation of going of self-propelled vehicle force of inertia itself to brake exactly.
Structure of the present utility model is that brake plunger 1 is sleeved in the caliper 16, between caliper 16 and the piston 1, oil sealing 3, dust protecting cap 4 is arranged.One end of caliper 16 is connected with outer hoof 2 by bolt 8.The flange of piston 1 is connected with another outer hoof 2 by bolt 8.Totally four of stay bearing plate 13() two ends respectively are connected with bracing frame 5, outer hoof 2 respectively by pin 12, and caliper 5, piston 1, shoe plate (containing outer hoof 2, interior hoof 9) part are supported on the bracing frame 5 by four stay bearing plates 13.Stay bearing plate 13 can rotate relative to pin 12.Bracing frame 5 is installed on the self-propelled vehicle (as steering swivel etc.) by lining 14, bolt 15 makes the whole bracing frame 5 can be according to the stressed difference in rotor 6 both sides and in rotor 6 sway, to guarantee that the stressed of rotor 6 both sides equates, guarantee that in other words the positive pressure on glancing impact rotor 6 both sides equates.Bolt 10 fixation spring tabs 11.Shell fragment 11 acts on outer hoof 2 can be separated with rotor 6 rapidly to guarantee braking back shoe plate, and returns to original position.The gap of hoof 9 and rotor 6 in adjustable bolt 7 is used for adjusting.Oil sealing 3 and dust boot 4 play sealing and dustproof effect respectively.Fuel feed hole 17 system hydrodynamics.
Its principle of work is such, and braking liquid enters fluid cylinder by fuel feed hole 17, piston 1, caliper 16 is gone in the same direction, and overcome the elastic force of shell fragment 11, presses rotor 6 and produces friction force implementation braking.Effect because of friction force in braking makes rotor 6 drive shoe plates (hoof 2, interior hoof 9 outside containing) move along the tangential direction of rotor 6.Because the support of stay bearing plate 13, positive pressure increase, friction force that shoe plate is acted on the rotor 6 also increase thereupon, friction force makes rotor 6 drive shoe plate and further moves to the tangential direction that rotor 6 rotates, the positive pressure that impels again on the rotor 6 that moves of shoe plate increases, the positive pressure increase impels friction force to increase again, form the supercharging circulation like this, produced very strong braking force.When rotor 6 does not rotate (during parking) do not produce self energizing effort.
The utility model is simple in structure, can remedy the shortcoming that plate disc brake on the current small passenger car does not have self energizing effort, can satisfy in the reality the needed speed of a motor vehicle again and wish the requirement that braking force is big more more soon.Because of this drg has very strong self energizing effort, still can reach satisfied braking effect so on small passenger car, need not adorn brake booster (or servo-unit), so also be very economical.
Realizing best way of the present utility model, is to select the best interior hoof and the angle of gap between rotor and stay bearing plate and rotor, and guaranteeing has enough autosynergism fruits.
What this figure described is a width of cloth scheme drawing, and stay bearing plate and pin have been done semi-sictional view, and caliper and bracing frame have been done semi-sictional view respectively.
