Abstract
The utility model discloses a widened plate spring suspension system of a transportation semitrailer, which comprises a front spring bracket, middle spring brackets and a rear spring bracket. Both sides of the middle spring brackets are provided with three-axis balance arms; upper and lower axis clamps are respectively arranged between the front and the rear spring brackets and the middle spring brackets and between the middle spring brackets; the upper and the lower axis clamps are connected into one whole body by U-shaped bolts; a plurality of plate springs are stacked on the upper axis clamps; the plate springs are clamped on the upper axis clamps by the U-shaped bolts; both ends of the plate springs are correspondingly connected onto the three-axis balance arms on the corresponding sides of the front spring bracket and the adjacent middle spring brackets; one sides of the lower axis clamps are provided with hinged seats; adjustable pull rods are hinged on the hinged seats; the rod ends of the adjustable pull rods are hinged at the bottom of the front spring bracket and the bottoms of the middle spring brackets. The widened plate spring suspension system has a simple structure and is easy to implement and the service life of the suspension system is prolonged.
Description
Technical field
The utility model relates to the conveying semi-trailer field, and what be specially a kind of conveying semi-trailer widens the leaf spring suspension.
Background technology
Conveying semi-trailer is a kind of engineering truck commonly used.Traditional conveying semi-trailer is common leaf spring suspension, the wide 90mm of leaf spring, and spring bracket is coupling 90mm leaf spring structure, little, the poor stability of this suspension load-carrying capacity, in the situation of same bearer amount, the service life of suspension is short, and damage rate is high.
The utility model content
What the utility model purpose provided a kind of conveying semi-trailer widens the leaf spring suspension, and prior art conveying semi-trailer suspension load-carrying capacity is little to solve, the problem of poor stability.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of conveying semi-trailer widen the leaf spring suspension; It is characterized in that: include preceding spring bracket, back spring scaffold; Be provided with a plurality of middle spring brackets between the forward and backward spring bracket; The spring bracket both sides are respectively arranged with three spindle balance arms in each; Be respectively arranged with upper and lower axle card between the spring bracket between forward and backward spring bracket and the adjacent separately middle spring bracket, in a plurality of; Upper and lower axle card is an one by a pair of inverted U-shaped bolted connection; Stack a plurality of leaf springs that are inverted pyramid structure respectively on the axle card on each, the leaf spring each on the axle card is stuck in axle by clevis bolt and blocks, and the leaf spring two ends between preceding spring bracket and the adjacent middle spring bracket are connected on the three spindle balance arms of preceding spring bracket, adjacent middle spring bracket respective side; Leaf spring two ends between back spring scaffold and the adjacent middle spring bracket be connected to back spring scaffold, adjacent on the three spindle balance arms of spring bracket respective side; Leaf spring two ends between the middle spring bracket are connected on the three spindle balance arms of spring bracket opposite side in two, and said lower shaft card one side also is respectively arranged with hinged seat, is hinged with adjustable rod on the hinged seat respectively; Before adjustable rod rod end on the lower shaft card hinged seat between spring bracket and the adjacent middle spring bracket be hinged on before the spring bracket bottom, the adjustable rod rod end on the lower shaft card hinged seat between the adjustable rod on the lower shaft card hinged seat between the middle spring bracket, middle spring bracket and the back spring scaffold is hinged on respectively bottom the middle spring bracket of the same side mutually.
The utility model is simple in structure; Be easy to realize, broken through the carrying drawback of former conveying semi-trailer suspension, guaranteed the in-use performance of suspension effectively; Increase bearing capacity, strengthened stable, as to have reduced suspension probability of damage, prolonged the service life of suspension.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1.A kind of conveying semi-trailer widen the leaf spring suspension; Spring bracket 1, back spring scaffold 2 before including; Forward and backward spring bracket 1, be provided with between 2 a plurality of in spring brackets 3; Spring bracket 3 both sides are respectively arranged with three spindle balance arms 4 in each; Be respectively arranged with upper and lower axle card 5,6 between the spring bracket between forward and backward spring bracket 1,2 and the adjacent separately middle spring bracket, in a plurality of; Upper and lower axle card 5,6 is connected as one by a pair of inverted U-shaped bolt 7; Stack a plurality of leaf springs 8 that are inverted pyramid structure respectively on the axle card 5 on each, the leaf spring 8 each on the axle card 5 is stuck in axle by clevis bolt 7 and blocks on 5, and the leaf spring two ends between preceding spring bracket 1 and the adjacent middle spring bracket are connected on the three spindle balance arms of preceding spring bracket, adjacent middle spring bracket respective side; Leaf spring two ends between back spring scaffold 2 and the adjacent middle spring bracket be connected to back spring scaffold, adjacent on the three spindle balance arms of spring bracket respective side; Leaf spring two ends between the middle spring bracket 3 are connected on the three spindle balance arms of spring bracket opposite side in two, and lower shaft card 6 one sides also are respectively arranged with hinged seat 9, are hinged with adjustable rod 10 on the hinged seat 9 respectively; Before adjustable rod rod end on the lower shaft card hinged seat between spring bracket 1 and the adjacent middle spring bracket be hinged on before spring bracket 1 bottom, the adjustable rod rod end on the lower shaft card hinged seat between the adjustable rod on the lower shaft card hinged seat between the middle spring bracket 3, middle spring bracket and the back spring scaffold is hinged on respectively bottom the middle spring bracket of the same side mutually.
