Description
Technical field
The present invention relates to a kind of Vehicular brake device, particularly a kind of Disk brake apparatus for electric vehicle axle assembly.
Background technique
Along with the progress of society, nowadays the quantity of automobile is in continuous increase, vehicle exhaust has become one of environment primary pollution source, along with the environmental consciousness of people is in continuous enhancing, and the continuous minimizing of intrinsic natural resources on the earth, find automotive fuel alternative and become a problem demanding prompt solution, develop the electric vehicle of environmental protection thus, it has been the developing direction of future automobile, occupy a tiny space in the new-energy automobile field in future, the electric vehicle bridge matched also is urgently development and investigation.
The current braking device for electric vehicle is mainly the drum brake of rear axle wheel, but the shortcoming that drum brake is general has braking force poor stability, on different road surface, braking force alters a great deal, be not easy to control, and due to thermal diffusivity bad, there is heat fade phenomenon in drum brake, so present stage is badly in need of wanting the above shortcoming of drum brake system of electric vehicle, make electric vehicle brake stable performance, finally reach the object that can be equipped with high-end bus or coach production.
Summary of the invention
The object of the invention is the braking force poor stability existing for the drum brake system in order to solve present stage electric vehicle, on different road surface, braking force alters a great deal, be not easy to control, and due to thermal diffusivity bad, there is the shortcomings such as heat fade in drum brake, and a kind of Disk brake apparatus for electric vehicle axle assembly proposed.
To achieve these goals, present invention employs following technological scheme:
A kind of Disk brake apparatus for electric vehicle axle assembly, comprise semiaxis, a wheel hub is fixedly connected with in the outside of described semiaxis, it is characterized in that: on described semiaxis, be also socketed a brake disc, brake disc is fixedly connected on described wheel hub, connect a brake calipers coordinated with its braking on the disc brake rotor, described brake calipers comprises caliper, equal sliding connection keep plate in the both sides of caliper, two keep plate correspondences are arranged on the both sides of described brake disc, all be connected at the inner side surface of each keep plate and brake with brake disc the friction plate coordinated, wherein the outside of a keep plate also connect one with the pressure wall of its pressure fitted.
On the basis of technique scheme, following further technological scheme can be had:
The side of described brake disc is provided with a flange plate.
Be provided with in described wheel hub and be socketed with described semiaxis the ladder hole coordinated, the first flange and the second flange is respectively equipped with in the both sides of wheel hub outer wall, uniform one group of first flange fluting on described first flange, uniform one group of second flange fluting on described second flange, described first flange fluting and the second flange fluting shift to install.
Described first flange is fixedly connected with described brake disc by link.
Uniform one group of first mounting hole on described first flange, uniform one group of second mounting hole on the second flange, all staggered 30 ° of angles of arbitrary neighborhood two the first mounting holes and the second mounting hole are arranged.
Described wheel hub adopts two flange arrangement, makes it have following advantage:
1, two flange arrangement meets the requirement that separate unit bridge has biased size, makes to load onto tyre rim rear tyre center line and is still positioned at hub bearing gear core.
2, two flange mounting hole is staggered into the requirement that 30 ° of angles meet assembling brake disc connecting bolt, again saves cost of material.
3, two braking surfaces of its supporting brake disc adopt column to connect, and thermal diffusivity is better, and contour structure is simple, make brake disc be convenient to processing, make brake disc computing ballance correction obviously reduce simultaneously.
4, whole bridge lightweight, wheel hub adopts the two flange arrangement of formula of diverging to namely to meet matching requirements, saves materials'use amount again, 30KG lighter than back axle of the same type, reduces weight, indirectly increase the enforcement mileage of car load under the prerequisite meeting existing performance.
The present invention has the following advantages:
1, better heat stability, this is because brake disc to lining pad without friction boosting function, also because the size of drag friction pad is not long, the area of its working surface is only 12% ~ 6% of brake drum area, therefore thermal diffusivity is better.
2, water stability is better, because the unit pressure of brake shoe to dish is high, is easily extruded by water, also be easy to get rid of after getting wet under the influence of centrifugal force simultaneously, add the wiping action of pad to dish, thus, after water outlet, only need can recover normal through first and second braking; Drum brake then needs can recover normal brake application usefulness through more than ten brakings.
3, insensitivity is good, the braking moment of disk type braker and the piston thrust of brake cylinder and friction factor linear, add without growth trend effect voluntarily, therefore in braking process, braking moment increases gentler, compared with drum brake, high insensitivity can be ensured.
4, the lining pad of disc type is more easily changed upon wear than the friction facing of drum-type, and structure is comparatively simple, and maintenance easily.
