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 generally adopt aspect braking 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 object of the invention is to, 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, make it stressed evenly after assembling with floor pan assembly, 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 present invention realizes above-mentioned purpose by the following technical solutions:
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 Eight characters shape and are arranged in the right and left of 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 present invention's 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 in the bottom of left and right fixed plate, be manufactured with positioning hole, 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 use, 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.
