Description
Technical field
This utility model relates to automotive brake field, and the balance of the automobile after a kind of improvement increases brake.
Background technology
Brake can divide two big classes, and industry brake and automotive brake, automotive brake is divided into again running brake and parking brake.When driving, service brake is the most all used, it is simple to ramp to stop during advancing, is the most singly to make automobile remain stationary as.If just using parking braking when service brake is malfunctioning.It is necessary to use parking braking after car comes to a complete stop, prevent vehicle forward and rear row.Make mechanical operating part stop or the moment of resistance that must apply of slowing down is referred to as braking moment.Braking moment is design, the foundation selecting brake, and its size is determined by pattern and the job requirement of machinery.In brake, the performance of brake component used directly affects braking procedure, and the principal element affecting its performance is operating temperature and temperature rise speed.
Drum brake is the brakes of Earlier designs, and the main flow of present drum brake is internal expanding type, and its brake-shoe is positioned at inside braked wheel, and brake when, brake block is flared out, and the inner side of frictional damping wheel reaches the purpose of brake.Its low cost, and meet traditional design, for heavy goods vehicles, owing to speed is generally not the highest, the robustness of brake shoe is also high than disk brake, and therefore many heavy goods vehicles the most still use the design of four hub types.
Balancing brake refers to that the pressure equilibrium that double brake-shoe acts on brake drum wall is consistent, and his brake efficiency is high, and stability, reliability are preferable, is to weigh the purpose important indicator that braking ability is good and bad.
Reinforcement braking refers in braking procedure, and brake-shoe obtains a kind of new pressurized energy by moment of friction conversion on brake drum wall.Its subsequent load and moment of friction be changed to conversion, vehicle braking force can be automatically adjusted.
It is leading trailing shoe brake that brake-shoe rotates, around hoof axle, the brake opened.Neck hoof outer opening can compress brake drum under the effect of moment of friction automatically, produces moment relatively big, also referred to as leading shoe.From Ti Zechao center, pine moves back, and produces moment less, also referred to as trailing shoe.According to the difference of Zhang Ti mechanism, neck is divided into equilibrium and non-equilibrium two kinds from shoe type, and in drum shoe brake performance classification arrangement, in the case of coefficient of friction is identical, balancing force amplifying brake efficiency is the highest, and neck is minimum from the usefulness of the non-equilibrium braking of shoe type.
At present, there is brake efficiency in non-equilibrium brake and thermal diffusivity is the most poor, the brake force poor stability of brake, and brake force changes the most greatly, is difficult to control；And owing to heat dispersion is poor, substantial amounts of heat can be assembled in braking procedure, brake block and wheel hub are easier to extremely complex deformation under the influence of high temperature, easily produce fading of brake and the phenomenon that flutters, retardation efficiency is caused to decline, therefore the braking ability of non-equilibrium brake is poor, and the phenomenon of whipping, sideslip easily occurs in braking procedure, time serious, even result in the generation of security incident.
