Abstract
The invention relates to a non-steering support shaft type 8X2 vehicle. The vehicle is characterized in that a non-steering support shaft is connected between a front double shaft of a driving bridge and a middle support shaft; a support shaft assembly is assembled on the whole vehicle by a support shaft plate spring assembly, a rear plate spring hanger, a bushing assembly, a plate spring front bracket and a plate spring rear bracket; wheels and tyre assemblies are assembled on the support shaft assembly to form a third shaft for the whole vehicle; and the support shaft and a rear bridge share the plate spring brackets. The invention has the advantages of preserving energy, reducing cost, increasing economic benefit, enlarging product variety, enhancing product competition and satisfying requirements of users, and is a four-shaft vehicle with low unladen mass and high load quality utilization coefficient.
Description
Technical field:
The present invention relates to a kind of non-turning to and support shaft type 8X2 vehicle, be used to liberate CA1241P7K2L11T9/CA1240P9K1L11T9 type 8X2 car.
Background technology:
Along with the enforcement of GB1589-2004 standard and the heavy fees policy of note, the highway in China situation is constantly improved, and administrative measure is constantly strengthened, the enforcement of strong policy such as weight metering charging, and the user is tending towards rational gradually to vehicle operation.
Summary of the invention:
The object of the present invention is to provide a kind of non-turning to support shaft type 8X2 vehicle, it adopts the midship mounting axle, before drive axle, increase the non-pivot shaft that turns to, carry mode with preceding twin shaft and midship mounting bearing, with the pivot shaft replacement duplex perforation drive axle of common driving rear axle in conjunction with non-driving, about 10000 yuan of cost savings; For satisfying the requirement of car load braking, adopted sense to carry a control cock and an automatically controlled relay valve first simultaneously,, captured owing to increase driving difficulty that reach causes, brake and turn to a series of difficult problems such as grinding tire by adjusting the relation between three or the four axle suspension framves.
Technical scheme of the present invention is achieved in that the non-support shaft type 8X2 vehicle that turns to, it is characterized in that: before drive axle, be connected with the non-pivot shaft that turns between twin shaft and the midship mounting axle, the pivot shaft assembly is assembled on the car load by pivot shaft steel plate spring assembly, rear leaf spring suspension ring and bush Assembly and spring front end bracket and steel spring after poppet, wheel and tire assembly are assembled to becomes the car load third axle on the pivot shaft assembly, the shared spring carrier of pivot shaft and back axle.
Good effect of the present invention is that it has energy savings, cost-cutting, increase economic benefit, expands product variety, improves competitive power of product and meet consumers' demand, and is that a curb mass is low, the eight-wheeler that charge material amount factor of utilization is high, i.e. 8 * 2 vehicles.
1, new suspension frame structure is mated in the application of midship mounting axle, and third axle is a pivot shaft, and rear-axle drive, middle back axle suspension are steel spring formula dependent suspension structure;
2, compare with the 8X4 chassis, with the carrying bridge replacement duplex perforation drive axle of common driving rear axle in conjunction with non-driving, save balance shaft, support and back reaction rod and main reduction gear and semiaxis etc. in the balancing suspension system, about 10000 yuan of cost savings, the light 980kg of while complete vehicle curb weight, the complete vehicle quality factor of utilization effectively improves, and has reduced the unit transport cost;
3, simultaneously for satisfying the requirement of car load braking, adopted sense to carry control cock and automatically controlled relay valve first, according to the braking force of different loads control pivot shaft.Solved in the process of the test, owing to the too small glancing impact that causes of jackshaft axle load, the problem of locking in advance.When unloaded in addition, the back axle braking force is enough, can not brake by jackshaft by automatically controlled relay valve, and actv. has reduced wear on tyres.
Description of drawings:
Fig. 1 is the structural representation of car load of the present invention;
Fig. 2 is a structural representation of the present invention;
Fig. 3 is a pivot shaft assembly structure scheme drawing of the present invention;
The specific embodiment:
The present invention will be further described below in conjunction with drawings and Examples: as shown in Figure 1, 2, 3, non-turning to supported shaft type 8X2 vehicle, it is characterized in that: before drive axle, be connected with the non-pivot shaft that turns between twin shaft and the midship mounting axle, pivot shaft assembly 1 is assembled on the car load by pivot shaft steel plate spring assembly 2, rear leaf spring suspension ring and bush Assembly 3 and spring front end bracket 5 and steel spring after poppet 4, wheel and tire assembly 6 are assembled to then becomes the car load third axle on the pivot shaft assembly 1, the shared spring carrier 4 of pivot shaft and back axle.
J5M 8X2 load-carrying vehicle, be on the basis of original J4 vehicle, draw original dynamic assembly and chassis system maturation, the reliable and high advantage of cost performance, carry out product improvement and cost and improve, this car has mated 7 kinds of economy such as BF6M1013-24, BF6M1013-26, BF6M1013-28, CA6DE2-22, CA6DF2D-22, CA6DE2-24, CA6DF2-24, environment protecting type engine; Three kinds of change speed gear boxs of 6T138,7T156 and 8JS118 have been mated; Coupling heavier-duty φ 395 and φ 430 clutch on-off devices, hydraulic pressure gas power controls, road-holding property is more comfortable; Adopt domestic top liberation superpower " 457 " back axle; The brake system brake strap is widened to 200mm, the braking safety and reliability; Adopted the brand-new J5M operator's compartment attractive in appearance of liberation.
With the CA1241P7K2L11T9 type is example, the calculating of adhesive ability,
CA1241P9K2L11T9 type goods carrying vehicle curb mass G0=9115kg, one, two front axle load 2235/2235kg, (in) back load on axle journals 965/3410kg
The CA6DF2D-22 driving engine, Ttq=770Nm
Ft＝Ttq*ig*i0*η/r＝770*10.111*4.875*0.92/0.509＝68600N
General starting stage driving engine can not perform to the torque peak situation, and empirical value is 70%, i.e. Ft1=Ft*70%=48020N
Zero load, the drive axle axle load is: 3410kg
The resistance of normally running at high speed is:
FF＝Ff+Fw＝N*f+0.5*Cd*ρ*A*V

The resistance of normally running at high speed is:
FF＝Ff+Fw＝28000*9.8*0.009+2459＝2526+2459＝4928N
Adhesive ability on good cement road of dried level or the pitch under the maximum grip coefficient:
Fψ1＝15400*0.8*9.8＝120736N
Adhesive ability on good cement road of level of wetness or the pitch under the maximum grip coefficient:
Fψ2＝10988*0.4*9.8＝60368N
F ψ 1＞FF normally runs at high speed at dry pitch or cement pavement and can not skid
F ψ 2＞FF normally can not skid at moist pitch or cement pavement high speed driving
Ft1＜F ψ 1 explanation can start to walk in the maximum acceleration of normal dry pavement;
Ft1＜F ψ 2 explanations can start to walk in the maximum acceleration of normal dry pavement.
Situation three
Overload 21885kg, lorry gross weight G is total=31000kg, the drive axle axle load is: 17505kg
The resistance of normally running at high speed is:
