Background technique
Along with the high speed development of Domestic Automotive Industry, the vehicle of various commercial vehicles also emerges in an endless stream, and has formed all kinds of car loads and component production and the matching system of many kinds, complete series.But the light card automobile below 2 tons, what aspect braking, generally adopt is all oily braking system, and oily brake is due to the problem that has hysteresis and instant impact, and poor stop, brake not steady.In order to address this problem, all change now the gas braking into, but the floor pan assembly distortion often appears in existing gas braking system, causes camshaft not at rotating center, causes the brake sideslip, in using process, the deformation rate of floor pan assembly is greatly about more than 60%.By the analysis to the floor pan assembly Deformation Reasons, its subject matter is that the stiffening plate structure shape design of connecting bottom board assembly and bracket assembly is unreasonable, discontinuity and too small with the surface of contact of floor pan assembly due to (referring to accompanying drawing 1).
Summary of the invention
The purpose of this utility model is, the stiffening plate that provides a kind of gas for light card automobile below 2 tons to stop the front brake floor pan assembly, this stiffening plate reasonable in design, after assembling with floor pan assembly, make it stressed evenly, and can strengthen the bulk strength of floor pan assembly, steadily, stopping distance is short to guarantee in light card vehicle traveling process braking, the braking left and right is synchronous, has good braking quality.
The utility model is to realize by the following technical solutions above-mentioned purpose:
The stop stiffening plate of front brake floor pan assembly of this gas consists of bracket assembly connecting plate, left fixed plate and right fixed plate, and it is characterized in that: the middle part of bracket assembly connecting plate is manufactured with a support attachment hole, and the left and right sides of support attachment hole is manufactured with fixed hole; Left fixed plate and right fixed plate are the right and left that Eight characters shape is arranged in the bracket assembly connecting plate, and the bottom of left fixed plate and right fixed plate is manufactured with positioning hole; The upper end of described left fixed plate and right fixed plate is 60mm apart from a, and the lower end distance b of left fixed plate and right fixed plate is 206mm, and the centre distance c of two positioning holes is 199mm, and the centre distance d of two positioning holes and support attachment hole is 50.5mm.
The utility model beneficial effect compared with prior art is:
The stop stiffening plate of front brake floor pan assembly of this gas is Eight characters shape at the right and left of bracket assembly connecting plate and is manufactured with the left and right fixed plate, and be manufactured with positioning hole in the bottom of left and right fixed plate, after making stiffening plate be riveted on the brake backing plate assembly, the ability that can make base plate bear torsion in axial and radial direction improves greatly, and accurate positioning is installed.Gas is stopped after the front brake floor pan assembly installs this stiffening plate additional, and the front axle assys that can adapt to 2 tonnes light card automobiles, minor works car, low-speed truck are used, and have stronger braking ability, and steadily, stopping distance is short in braking, and the braking left and right is synchronous.Thoroughly having solved the stiffening plate of floor pan assembly in the prior art designs unreasonable, the easy gross distortion of base plate during automobile brake, brake sideslip or brakeless while causing braking, the braking ability extreme difference, can not meet the problem that light card automobile front axle assembly gas is stopped the growing needs of front braking.
The accompanying drawing explanation
Fig. 1 is the stop structural representation of stiffening plate of front brake floor pan assembly of gas;
Fig. 2 is the gas stiffening plate of the front brake floor pan assembly structural representation after installing of stopping.
In figure: 1, bracket assembly connecting plate, 2, left fixed plate, 3, right fixed plate, 4, the support attachment hole, 5, fixed hole, 6, positioning hole.
Embodiment
The stop stiffening plate of front brake floor pan assembly of this gas consists of bracket assembly connecting plate 1, left fixed plate 2 and right fixed plate 3, the middle part of bracket assembly connecting plate 1 is manufactured with a support attachment hole 4, the left and right sides of support attachment hole 4 is manufactured with fixed hole 5, for stiffening plate being riveted on to the brake backing plate assembly.Left fixed plate 2 and right fixed plate 3 are the right and left that Eight characters shape is arranged in bracket assembly connecting plate 1, the lifting surface area of floor pan assembly is increased be twice above, thereby greatly strengthened the resistivity that torsion that floor pan assembly produces because of braking causes plastic deformation.The bottom of left fixed plate 2 and right fixed plate 3 is manufactured with positioning hole 6, and the installation location is efficient and convenient.The upper end of described left fixed plate 2 and right fixed plate 3 is 60mm apart from a, and the lower end distance b of left fixed plate 2 and right fixed plate 3 is 206mm, is the opening angle of Eight characters shape in order to limit left fixed plate 2 and right fixed plate 3.The centre distance c of two positioning holes 6 is 199mm, and two positioning holes 6 are 50.5mm with the centre distance d of support attachment hole 4.
This gas front brake of stopping is a kind of equal shift type brake, if on equal shift type brake two shoe friction plates, corresponding point and the gap adjusted between brake drum are in full accord, while braking, two hoof must equate the compression degree of drum and the braking moment produced.But brake drum makes the neck hoof actuate end to the rubbing action of hoof to try hard to leave brake cam, make again to actuate end from hoof and more be close to brake cam simultaneously.Owing to not being centrosymmetric on the equal shift type brake structure, although two hoof act on the equivalence of the infinitesimal normal force of the brake drum equal and opposite in direction of making a concerted effort, but not on the same straight line, impossible balance mutually, can cause this break when braking, make base plate very large at the torsion of axial and radial direction, the problem of floor pan assembly distortion often occurs.This gas stops after the front brake floor pan assembly installs stiffening plate of the present utility model additional on base plate, greatly improved the gas ability that front brake bears torsion of stopping.
