Abstract
The utility model relates to a four-axle heavy truck chassis with a load-bearing axle. The first two axles are turning axles, a third axle is a driving axle, combined driving axle leaf springs formed by main leaf springs and auxiliary leaf springs are respectively arranged on two sides of the driving axle, supporting axle leaf springs are respectively arranged on two sides of a fourth axle which is a fourth supporting axle, the supporting axle leaf springs are integral main-auxiliary leaf springs and each main leaf spring is positioned above each auxiliary leaf spring. The four-axle heavy truck chassis with the load-bearing axle is in an 8*2 driving structure, fine in smoothness since a rear combined suspension system is variable in stiffness and the vehicle is small in stiffness when bearing no load or light load, good in economy due to low fuel consumption by adopting mono-axle drive. The supporting axle is in a non-lifting structure, so that damage to ground caused by difficult falling off of the supporting axle can be avoided. Due to the various stiffness of the suspension, axle loads can be reasonably distributed when the vehicle bears no load or light load, and the driving axle can be ensured to be provided with enough axle loads, so that the vehicle can be better in driving performance and passability.
Description
Technical field
The utility model belongs to the heavy-duty truck technical field, is specifically related to the multiaxis load-carrying vehicle chassis in the heavy-duty truck.
Technical background
Four heavy duty trucks of domestic-developed, 8 * 4 the drive forms that adopt more, promptly preceding diaxon is two-way steering shaft, back diaxon is a double drive axle.This drive form rear driving axle is that duplex is moving, guaranteeing can provide enough power for car load at full load, but when vehicle zero load or underloading, because the problem of the moving inner structure of drive axle of duplex own, the shared ratio of the power of its loss will rise, cause fuel oil consumption bigger than single driving rear axle, less economical.
Summary of the invention
At the big deficiency of watt loss height, fuel oil consumption that the moving drive axle of the duplex of existing four heavy duty trucks exists, the utility model provides a kind of simple in structure, four heavy-duty truck chassis that install the carrying bridge additional that cost is low.
Concrete Technological improvement plan is as follows:
A kind of four heavy-duty truck chassis that install the carrying bridge additional comprise operator's compartment, driving engine, change speed gear box, vehicle frame, front steering axle I, front steering axle II, third axle and the 4th bridge.
Described third axle is the 3rd drive axle, and the 3rd drive axle both sides are respectively equipped with the knockdown drive axle steel spring of being made up of main steel plate spring and additional leaf spring, and wherein additional leaf spring is positioned at the top of main steel plate spring; The front end of every secondary main steel plate spring is connecting vehicle frame by the leaf spring fixed support, the rear end is connecting vehicle frame by the leaf spring sectional shelf-unit, vehicle frame between leaf spring fixed support and the leaf spring sectional shelf-unit is provided with the auxiliary spring support, and the auxiliary spring support is corresponding with the front end of additional leaf spring.
Described the 4th bridge is the 4th supporting bridge, and the 4th supporting bridge both sides are respectively equipped with the supporting bridge steel spring, and the front end of every secondary supporting bridge steel spring is connecting the leaf spring sectional shelf-unit, and the rear end is connecting vehicle frame by the leaf spring shackle bracket; Described supporting bridge steel spring is an integral type major-minor steel spring, and the main steel plate spring is positioned at the top of additional leaf spring; Between supporting bridge steel spring bottom and the vehicle frame shock absorber is installed.
Described supporting bridge steel spring 10 front ends adopt the grasswort of flat placed type, are provided with rubber bush in the grasswort.
The utility model is the heavy-duty truck chassis of 8 * 2 drive configurations, adopts third axle as drive axle, and the 4th as supporting bridge.Because back combination suspension system is a stiffness variable, car load rigidity under zero load or underloading load is little, so ride comfort is good, and it is low to adopt single bridge to drive oil consumption, good economy performance.Supporting bridge is non-lifting structures, avoided since supporting bridge be difficult to fall cause to ground-surface damage, its suspension rate is variable, make zero load and fully loaded distribution of axle load all comparatively reasonable, guarantee that drive axle has enough axle loads, make the driven nature and the crossing ability preferably of having of vehicle.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the steel spring structural representation of the 3rd drive axle.
Fig. 3 is the steel spring structural representation of the 4th supporting bridge.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done to describe further by embodiment.
Embodiment:
Referring to Fig. 1, a kind of four heavy-duty truck chassis that install the carrying bridge additional comprise operator's compartment 1, driving engine 2, change speed gear box 3, vehicle frame 4, front steering axle I16, front spring spring I17, front steering axle II 14, third axle 13 and the 4th bridge 12.
Third axle 13 is the 3rd drive axle, and the 3rd drive axle both sides are separately installed with the knockdown drive axle steel spring of being made up of main steel plate spring and additional leaf spring 7, and wherein additional leaf spring is positioned at the top of main steel plate spring, sees Fig. 2; The front end of every secondary main steel plate spring is connecting vehicle frame 4 by leaf spring fixed support 5, the rear end is connecting vehicle frame 4 by leaf spring sectional shelf-unit 8, on the vehicle frame 4 between leaf spring fixed support 5 and the leaf spring sectional shelf-unit 8 auxiliary spring support 6 is installed, auxiliary spring support 6 is corresponding with the front end of the additional leaf spring of drive axle steel spring 7.When automobile reached certain carrying, the camber of main steel plate spring reduced, and made additional leaf spring contact with auxiliary spring support 6, thereby improved the rigidity of drive axle steel spring 7, guaranteed the load and the traveling comfort of vehicle.
Referring to Fig. 3, the 4th bridge 12 is the 4th supporting bridge, and the 4th supporting bridge both sides are separately installed with supporting bridge steel spring 10, and supporting bridge steel spring 10 is an integral type major-minor steel spring, and the main steel plate spring is positioned at the top of additional leaf spring.The front end of every secondary supporting bridge steel spring 10 is connecting leaf spring sectional shelf-unit 8, and the rear end is connecting vehicle frame by leaf spring shackle bracket 11.Bumper 9 one ends link to each other with shock absorber support on being installed on the workshop, and an end links to each other with the bumper downside pin of installing with in supporting bridge steel spring 10 bottoms, the offset frequency of reduction rear suspension.Supporting bridge steel spring 10 adopts the major-minor spring structure, has only the main steel plate spring work of drive axle steel spring 7 when vehicle zero load or underloading, and rigidity of plate spring is little, guarantees and the ratio of rigidity of drive axle steel spring 7, makes drive axle that enough propulsive efforts be arranged; The vehicle at full load, after the additional leaf spring work of drive axle steel spring 7, the additional leaf spring of supporting bridge steel spring 10 is also started working, and has kept the ratio of rigidity with drive axle steel spring 7, has realized the driving energy and the bearing type energy of car load.In addition, supporting bridge steel spring 10 front ends adopt flat placed type grasswort structure, have improved the safety factor of leaf spring grasswort; Increase rubber bush 18 in the middle of the grasswort, ground shock is for the impact of leaf spring and leaf spring grasswort in the time of can alleviating the vehicle heavy duty.
