Description
Technical field
The present invention relates to a kind of automobile front axle parts, in particular, relate to a kind of axle load and be the low-floor vehicle front axle of 5.5 tons.
Background technology
Automobile front axle has another name called front axle beam, and its cross section adopts respectively I-shaped and rectangle to improve bending resistance and torsional strength; Respectively there is a fist shape part at two ends, process kingpin bore and side pin-and-hole, can manipulate for installing two front-wheels that direction of advance again can support front weight, and middle part processes wider faces--the spring block of two place's supporting steel plate springs; Between two spring blocks, be bent downwardly to reduce automobile barycenter, expansion driving vision, increases practicality and comfortableness. Therefore, automobile front axle is one of important security member in automobile front axle assembly.
Along with the development of market economy, being growing more intense of vehicle price competition, countries in the world are development and application new technology competitively, new technology, new material makes great efforts to reduce manufacturing cost, simultaneously along with adapting to development and the intercity public transport of highway construction, the increase of town and country public transport to passenger vehicle demand, at present, on bus market, occur that some carry out improved low head passenger vehicle front axle for highway construction, but these passenger vehicle front axles or ubiquity bearing capacity is little, automotive floor panel is high, the problems such as central gangway is narrow, what is more important, a kind of automobile front axle that just can directly take passenger vehicle for the disable person and the personnel that become pregnant without any instrument is not still provided at present.
Summary of the invention
The object of the invention is to, for the problem of above-mentioned existence, the invention provides a kind of low-floor vehicle front axle, axle load is 5.5 tons, it is little that this passenger vehicle front axle not only can solve passenger vehicle fore bearing carrying capacity, automotive floor panel is high, the defect that central gangway is narrow, and can also make the disable person and the personnel that become pregnant just can directly take passenger vehicle without any instrument.
In order to reach object of the present invention, the technical scheme that the present invention takes is: a kind of low-floor vehicle front axle, comprise front axle girder, the fist shape part at front axle girder two ends is respectively provided with a kingpin bore, the side of each kingpin bore is respectively equipped with the side pin-and-hole of a cooperation, on front axle girder, be also provided with two symmetrical spring blocks, on described spring block, be placed with multiple leaf spring holes, described in it, between two spring blocks, be girder face, the axis of described kingpin bore is with respect to 7 ° of the vertical vertical line introversions of spring block, the diameter of described kingpin bore is 47mm, the diameter of side pin-and-hole is 16mm, the centre distance of two kingpin bores is 1873.3mm, the first normal throw of the center of described kingpin bore and spring block upper surface is 120mm, the second normal throw of described spring block upper surface and girder face is 85mm, distance between two spring blocks is 930mm.
Further, the cross section of described front axle girder is to be formed to one group of cross section of the I-shaped cross-section Zai Dao square-section gradual change on both sides respectively by middle square-section, reaches and has reduced material consumption, strengthens bending resistance torsional strength, economical and practical object.
Further, the material selection 42CrMo of passenger vehicle front axle of the present invention, after forging, through heat treatment quenching and tempering, final machine add-on type, guarantees the quality of important security member.
Beneficial effect of the present invention: the increasing of microbus front axle the first drop of the present invention and the second drop, reduce to a greater extent car load center of gravity, like this, the one, effectively increase the safety coefficient of travelling, ensure the security of driving, smoothness, stability, comfortableness, the 2nd, be more beneficial to disabled person and the personnel that become pregnant can be directly upper and lower, improve punctual rate; Distance between kingpin bore and spring block strengthens, and has expanded the width of automobile center-aisle, has strengthened bearing capacity, has facilitated passenger to move, and increases riding stability.
The low-floor vehicle front axle that the present invention is 5.5 tons is to find after the low-floor vehicle bridge comprehensive survey on market in the past: existing passenger vehicle or vehicle body long (13m-18m), cause trafficability characteristic poor, tonnage is laid particular stress on shipper pole in (7.5t-9t) center of gravity and is carried out potential safety hazard, upper and lower difficulty (marking time for 2 grades-3 grades), to this, we have made the present invention and have solved the problems referred to above, simultaneously, the present invention draws through overtesting, the CKZ6116N4 public transport vehicle of front axle counterweight celebrating Heng Tong of the present invention, this vehicle body is long generally in 10m left and right, 5.5 tons of left and right of tonnage, because load-carrying is few, vehicle body is short, trafficability characteristic and security at the bottom of barycenter, are greatly improved, while particularly joining the logical ZK61118H public transport vehicle of space, greater advantages are brought into play: this car bright spot is " 10 meters of one deck used cars ", be to have increased by 6 parking stalls after driver's compartment sinks, Market Feedback: operation benefits is different, outward appearance imposing manner is different, ride experience is different, energy-saving efficiency is different, easily control different, safe and efficient different.
