Abstract
A kind of heavy-duty vehicle and two straight propelling rod constitutional balance suspension are provided, equalizing-suspension device comprises two independent distance rod assemblies and is arranged symmetrically with, wherein each distance rod assembly one end is bolted on axle end propelling rod support, the other end is bolted on the propelling rod support of vehicle frame end longeron, with in, rear axle can adopt two groups two independent straight upper thrust rod assemblies when being connected.The design of two trammel beam, vehicle frame end thrust rod bearing can directly be connected with longeron, the power of propelling rod no longer needs through crossbeam, be directly passed to chassis side rail, thus avoid the fault of crossbeam and crossbeam connection, and then according to the actual load situation design thrust bar intensity of suspension, can no longer be limited to crossbeam and its Joint strenght.In addition, two independent straight propelling rods turn avoid the defect that traditional V-type propelling rod fault is higher and vehicle bridge path of motion is limited; Two independent upper thrust rod structures turn improve the safety of car load.
Description
Technical field
The utility model relates to heavy transportation machinery field, particularly relates to a kind of heavy-duty vehicle and balance suspension, belongs to car chassis system.
Background technology
The heavy-duty vehicle balance suspension of early development generally adopts Dan Shangzhi propelling rod structure, and vehicle frame end thrust rod bearing is arranged on cross member of frame, and the power of propelling rod needs to pass to longeron through crossbeam.But along with the continuous increase of tonnage, easily there is upper thrust rod fracture, crossbeam tear, the fault such as propelling rod and crossbeam tie bolt loosens, fracture, even cause the related property fault that vehicle bridge upset, transmission shaft damage etc. are more serious after fault; Traditional V-type propelling rod has the defect that fault is higher and vehicle bridge path of motion is limited in addition.
Utility model content
For the above technical issues that need to address, provide a kind of heavy-duty vehicle and two straight propelling rod constitutional balance suspension, it can make up deficiency of the prior art, effectively ensures reliability and other performance of balance suspension.
A kind of two straight propelling rod constitutional balance suspension, adopt first, second distance rod assembly, first, second distance rod assembly is arranged symmetrically, each distance rod assembly two ends connect axle end and vehicle frame end respectively, vehicle bridge and vehicle frame are respectively equipped with bearing, and bearing is connected respectively by attaching parts with distance rod assembly two ends.
Further, vehicle frame end bearing can be arranged on longeron.
Further, axle end bearing is arranged on vehicle bridge crossbeam midway location.
Further, attaching parts is bolt, nut.
Further, the bearing that each distance rod assembly is connected with vehicle frame end is arranged separately.
A kind of two straight propelling rod constitutional balance suspension, with in, rear axle is connected is two groups two independent straight upper thrust rod assemblies, wherein often group adopts first, second distance rod assembly, first, second distance rod assembly is arranged symmetrically, each distance rod assembly two ends connect axle end and vehicle frame end respectively, vehicle bridge and vehicle frame are respectively equipped with bearing, and bearing is connected respectively by attaching parts with distance rod assembly two ends.
Further, vehicle frame end bearing can be arranged on longeron.
Further, axle end bearing is arranged on vehicle bridge crossbeam midway location.
Further, attaching parts is bolt, nut.
The bearing that two groups of dual thrust bar assemblies are connected with vehicle frame end and axle end is whole installation.
A kind of heavy-duty vehicle, it adopts the two straight propelling rod constitutional balance suspension of above-mentioned either a program.
Two independent straight propelling rods avoid the defect that traditional V-type propelling rod fault is higher and vehicle bridge path of motion is limited, and two propelling rod constitutional balances are better, can beam stressed of balance frame, alleviate Joint strenght, improve the safety of car load.Particularly vehicle frame end thrust rod bearing can directly be connected with longeron, and the power of propelling rod no longer needs through crossbeam, is directly passed to chassis side rail, thus avoids the fault of crossbeam and crossbeam connecting bridge; And then according to the actual load situation design upper thrust rod assembly intensity of suspension, can no longer be limited to crossbeam and its Joint strenght.
As can be seen from above scheme, adopt two straight propelling rod balance suspension structure, while meeting various performance parameters, the reliability of this device can also be ensured, improve the safety of vehicle.
Accompanying drawing explanation
Fig. 1: the two straight propelling rod constitutional balance suspension frame structure figure of the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Two straight propelling rod constitutional balance suspension, comprising: axle end propelling rod support 1, tie bolt 2, nut 3, upper thrust rod assembly 4, tie bolt 5, vehicle frame end thrust rod bearing 6.
Concrete annexation is, two independent upper thrust rod assemblies 4 and axle end propelling rod support 1 couple together by tie bolt 2, nut 3; Upper thrust rod assembly 4 and vehicle frame end thrust rod bearing 6 couple together by tie bolt 5.
In a preferred embodiment, adopt the balance suspension of two groups of two straight propelling rod structures, propelling rod side is bolted on axle end propelling rod support, opposite side is bolted on vehicle frame end thrust rod bearing, vehicle frame end thrust rod bearing can directly be connected with longeron, symmetrical one end fixing two distance rod assemblies on the overall bearing of axle end, on the overall bearing of vehicle frame end, same symmetry fixes the other end of two distance rod assemblies.Bearing also can be arranged separately.
Structure according to above preferred embodiment, two propelling rod constitutional balances are better, can beam stressed of balance frame, and the power of propelling rod no longer needs through crossbeam, is directly passed to chassis side rail, thus avoids the fault of crossbeam and crossbeam connecting bridge; And then according to the actual load situation design upper thrust rod assembly intensity of suspension, can no longer be limited to crossbeam and its Joint strenght.In addition, two independent straight propelling rods turn avoid the defect that traditional V-type propelling rod fault is higher and vehicle bridge path of motion is limited; Two independent upper thrust rod structures have the beneficial effect of the safety improving car load.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to detailed description of the invention of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
