Abstract
The utility model relates to a balance shaft mechanism suitable for a heavy duty truck balance suspension, and solves the problem that the heavy duty truck balance shaft support saddles are exposed to crack when in service. The balance shaft mechanism comprises a balance connection core shaft, wherein, balance shaft support saddles are fixedly connected to two ends of the balance connecting core shaft, a plate spring holder is coaxially connected to the other side of each balance shaft support saddle, the upper part of each balance shaft support saddle adopts a connecting plate surface connected to the vehicle frame, the lower part thereof adopts a support saddle support body, strip-shaped strengthening ribs are uniformly arranged on two sides of the space between the vehicle frame connection surfaces of the balance shaft support saddles and the balance shaft support saddle support bodies, the strip-shaped strengthening ribs are vertical to the axial direction of the balance connection core shaft, and the wall of the main body of each balance shaft support saddle is 14 mm in thickness. In short, the improvement over the heavy duty truck balance shaft assembly has the benefits of improving the load-bearing performance of the balance shaft assembly to a certain degree, and meanwhile reducing the dead weight to a certain degree.
Description
Technical field
The utility model relates to the balance shaft mechanism that is applicable to the heavy duty truck balance suspension.
Background technology
At present, the various equalizing suspension systems that heavy motor vehicle uses, mainly due to the overload transportation, when perhaps under abominable road conditions condition, travelling, reasons such as the formation enormous impact power of jolting because of vehicle, cause the trunnion base cracking frequent, carry out comprehensive comparative analysis through the various balance suspension series of products damaged conditions that heavy type commercial automobile is used, the major failure that trunnion base occurs is: trunnion base from the bolt cracking that connects to ground, trunnion base breaks from the U-bolt hole and trunnion base ruptures from adapter shaft bearing etc.Also carried out repeatedly improving at above-mentioned these problem people in early stage, handle as trunnion base being carried out overstriking thickening, the R angle at each faying face place is strengthened and a series of measures such as the base plate thickening that connects to ground, all can't well solve the problem of trunnion base cracking.
Summary of the invention
For solve the goods carrying vehicle trunnion base use in problem easy to crack, the utility model provides a kind of reliability height, in light weight, cost is low, assembling the is easy to maintenance novel balance shaft mechanism that is applicable to the heavy duty truck balance suspension.
Concrete structural development technical scheme is as follows:
The balance shaft mechanism that is applicable to the heavy duty truck balance suspension comprises that balance connects mandrel 1, and balance connects the two ends difference captive joint of mandrel 1 and trunnion base 2, the coaxial leaf spring bracket 3 that connecting of the opposite side of each trunnion base 2; The top of trunnion base 2 is the connecting panel face that connects to ground, and its underpart is the seat supports body,
The both sides of vehicle frame bonded assembly surface between the trunnion base supporter of described trunnion base 2 are laid with strip reinforced rib 6 respectively, and strip reinforced rib 6 connects the axis direction of mandrel 1 perpendicular to balance.
The connecting panel face and the both sides between the seat supports body of described trunnion base 2 are laid with two strip reinforced ribs 6 respectively.
The main body wall thickness of described trunnion base 2 is 14 millimeters.
Useful technique effect of the present utility model is mainly reflected in two aspects:
One, between connecting panel face that left and right sides main body trunnion base connects to ground and trunnion base supporter, increases a series of reinforced ribs, make the bearing force of trunnion base obtain bigger reinforcement;
Two, on the basis that guarantees balance shaft assembly carrying reliability, with left and right sides trunnion base main body wall thickness reduction, when guaranteeing load-carrying capacity bigger reduction the own wt of trunnion base.
By the improvement to the heavy duty truck balance shaft assembly, make the load-carrying properties of balance shaft assembly obtain certain raising in a word, own wt has also had certain decline simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the C-C cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1 and Fig. 2, the balance shaft mechanism that is applicable to the heavy duty truck balance suspension comprises that balance connects mandrel 1, balance connects the net-size forging of mandrel 1 for the band blind hole, balance connects the two ends difference captive joint of mandrel 1 and trunnion base 2, the coaxial leaf spring bracket 3 that connecting of the opposite side of each trunnion base 2, leaf spring bracket 3 outsides are fixed by balance shaft end cap 4.The top of trunnion base 2 is the connecting panel face that connects to ground, and its underpart is a seat supports body 5.
The both sides of vehicle frame bonded assembly surface between the trunnion base supporter at trunnion base 2 are laid with two strip reinforced ribs 6 respectively, and strip reinforced rib 6 connects the axis direction of mandrel 1 perpendicular to balance; Make the bearing force of trunnion base obtain bigger reinforcement.
The main body wall thickness of trunnion base 2 is 14 millimeters, when guaranteeing load-carrying capacity bigger reduction the own wt of trunnion base; Thereby reduced balance shaft mechanism single-piece weight.
