Description
Technical field
It the utility model is related to automobile brake technical field, and in particular to a kind of oil immersion double plate platen brake.
Background technology
Automotive brake is the brake apparatus of automobile, and the brake used in automobile is nearly all frictional, can be divided into drum
Two major class of formula and disc type.Rotate element during disk brake friction is secondary is the rosette to be worked with end face, is known as brake disc.
Friction element clamps brake disc from both sides and produces braking.Retaining element then has multiple structural forms, generally can be by disc type system
Dynamic device is divided into two class of caliper disc and complete-disc.
Braking is generally formed by the little brake pad of 2~4 pieces of work areas and its metal backing in spot-type disc brake
Block.These brake block and its actuating device are incorporated into the clamp-shaped stent of brake disc both sides, are known as caliper.Caliper disc
Brake cooling capacity is strong, and heat endurance is good, therefore is widely used on most of cars and pickup truck.
The secondary retaining element of complete disc brake friction and rotate element are all discoidal, are referred to as fixed disk and rotation
Turntable.Whole working faces of brake disc can be contacted with friction plate at the same time, its structural principle is similar to friction clutch.In heavily loaded goods
Used under the occasion of automobile or other big brake force of needs.
Compared with drum brake, disk brake working surface conducts heat for plane and two sides, and disc rotary easily cools down,
Moderate finite deformation is not susceptible to, brake efficiency is relatively stable, for a long time using rear brake disc because high-temperature expansion strengthens braking action；
And drum brake single side conducts heat, the inside and outside two sides temperature difference is larger, causes brake drum to be easily deformed, while for a long time after braking, system
Dynamic drum is expanded because of high temperature, and brake efficiency weakens.In addition, disc-like brake structure is simple, and it is easy to maintenance, easily realize brake clearance
Adjust automatically.It is disk brake rapid heat dissipation, light-weight, simple structure, easy to adjust.Particularly high load when resistance to elevated temperatures
Good, braking effect is stablized, and is not afraid of muddy water invasion and attack, the disc type system used in the winter time with severe road conditions down train, many cars
Dynamic device have plane formula brake disc, perforating type brake disc and line formula brake disc, wherein line formula brake disc braking effect and
Ventilation and heat ability is relatively good.
Disk brake is disadvantageous in that friction plate is acted directly on disk, no automated friction boosting function, system
Dynamic efficiency is relatively low, if required brake actuation loine pressure is higher when institute is for brake fluid system, it is auxiliary must separately to install power
Help device；When being used for parking braking, the parking braking transmission device ratio drum brake of installation is complicated, thus on trailing wheel
Application be restricted.
Utility model content
The utility model aims to provide that a kind of brake force is big, the oil immersion double plate platen brake of rapid heat dissipation.

The good effect that the utility model produces is as follows：
The friction area bigger of the utility model, using the teaching of the invention it is possible to provide more preferable braking effect.Compared with conventional jaw type braking,
The utility model employs press disc type braking, and friction area increases sharply, and when driver is braked, big friction area can be fast
Speed provides enough frictional force, converts kinetic energy into thermal energy within the shorter time, shortens the braking distance of vehicle.
The service life of the utility model is longer.In the case where pressure is certain, friction area increase, then on unit area
Drop of pressure, the rate of depreciation of friction plate also declines therewith, and the time used is also longer.
The heat dissipation effect of the utility model is more preferable, and braking ability caused by can effectively avoiding thermal deformation declines.Braked
Journey is actually the process that kinetic energy is converted into other energy, and the kinetic energy that vehicle is had is converted into thermal energy consumption and falls.This conversion
Process is realized by the friction between friction plate.In friction process, friction plate temperature distortion, the area meeting of contact portion
Decline, cause frictional force to decline.The part pressure still contacted at this time can also steeply rise, and cause local stress concentration, rub
Pad part wears aggravate.For vehicle, the braking effect of vehicle can decline rapidly, cause poor stop, easily
Cause the generation of accident；The rate of wear of another aspect friction plate accelerates, it is necessary to the frequency replaced can also rise, or even some mills
Overall braking ability can be had an impact by damaging serious regional area, cause braking ability to decline going out for even brake fade
It is existing.Oil immersed type cooling is introduced in the utility model, friction plate is fully immersed in heat dissipation oil, on the one hand can completely cut off friction
Piece and extraneous contact, soil, rainwater, dust etc. are all completely cut off, ensure that the clean of friction plate；On the other hand braking
The heat that should be gathered on friction plate is transferred in heat dissipation oil in journey, can effectively reduce the thermal change in friction process
Shape, ensures braking effect.
The utility model employs the design of frictional force auxiliary supplement, can further increase friction to a certain extent
Power, improves braking effect.During conventional brake, piston A is promoted by hydraulic oil, the friction plate C being fixed thereon and friction
Piece A is contacted, the two contact friction force.When brake is floored, the pressure in hydraulic case body reaches capacity, and frictional force can not continue
Rise.Increase pressure can not obtain the pressure of bigger merely at this time, and the excessive housing of pressure can not also be born.Therefore,
The utility model adds auxiliary device, i.e., piston B is added on hydraulic pressure housing.Pressure can pass at the same time piston A and
Piston B, the stress on unit area reduce, and friction area rises, and the speed that kinetic energy is converted into thermal energy is accelerated, and braking effect also can
Rise.
