Abstract
The utility model relates to an equalizing suspension device used for improving the stress conditions of an equalizing suspension axle, a balancing shaft bracket and a balancing bearing hub. A heavy vehicle equalizing suspension device of the utility model comprises a balancing shaft bracket, an equalizing suspension axle and a balancing bearing hub and is characterized in that a false balancing shaft bracket is fixed on the chassis carline right above the balancing shaft bracket and the side close to the balancing bearing hub; a pin roll gets through the downwards extending part at the external end of the false balancing shaft bracket and the top of a balancing shaft end cover assembly and then is fixed at one side of the false balancing shaft bracket close to the chassis carline; the bottom of the balancing shaft end cover assembly is fixed on the equalizing suspension axle. The heavy vehicle equalizing suspension device changes the stress condition of the equalizing suspension axle as a whole so as to maximally avoid the damage of parts such as balancing shaft bracket and equalizing suspension axle.
Description
Background technology:
The various balance suspension products that existing heavy type commercial automobile uses, mainly due to the overload transportation, when perhaps under abominable road conditions condition, travelling, because of the jolt reason of the aspects such as huge inertial impact force that form of vehicle, cause parts frequent breakage such as balance suspension axle fracture, balance shaft support cracking, the fragmentation of equalizer bearing hub.Carry out comprehensive comparative analysis through the various balance suspension series of products damaged conditions that heavy type commercial automobile is used, get rid of the material of car load vehicle frame use and the difference that the manufacture craft aspect exists, the typical fault that damaging appears in equalizing-suspension device is mainly: the balance shaft support is from the bolt cracking that connects to ground, the equalizer bearing hub breaks from the U-bolt hole, the balance suspension axle of Dongfeng series or twist off from vehicle frame below near the balance shaft support is inboard, be sheared at balance shaft support and balance bearing hub joint portion, " 457 " series balance suspension product of one vapour liberation and Beijing Automobile Workshop's Feitian car load use is except that the balance suspension axle breaks from balance shaft support and balance bearing hub joint portion, the balance suspension thru shaft is usually from rupturing near the balance shaft support is inboard, the condition of service of the balance suspension product of Steyr car load assembling is more better relatively by contrast, but can not avoid balance suspension axle fracture phenomenon to take place.Early stage is at the terms of settlement of balance suspension product bug, mainly be to set about: the balance suspension axle is adopted forge the part blank and do to add bulk processing from the following aspects, the balance shaft support will be except that will thickening with the base plate of vehicle frame binding face, gusset has also been done respectively to strengthen handling everywhere, the transition R radian at each faying face place is suitably strengthened, the equalizer bearing hub adds fertilizer and widens even so-called " two card enhanced balance shafts hold hub " occurred, but produce little effect, and all can fundamentally not eliminate the reason that the balance suspension product frequently breaks down.
Summary of the invention:
The utility model proposes a kind of balance suspension axle that improves, the balance shaft support, the equalizing-suspension device of equalizer bearing hub force-bearing situation, a kind of heavy goods vehicles equalizing-suspension device of the utility model is by the balance shaft support, the balance suspension axle, the equalizer bearing hub constitutes, it is characterized in that, fix a balance shaft assistant support by the chassis side rail directly over the balance shaft support near equalizer bearing hub one side, extend downwards the outer end of described balance shaft assistant support, pass the upper end and the balance shaft assistant support of a downward balance shaft end cap of the partial sum assembly that extends in outer end of described balance shaft assistant support fixes near a side of chassis side rail by bearing pin, the lower end of described balance shaft end cap assembly is fixed on the balance suspension axle, form the utility model equalizing-suspension device, this device is at the balance shaft support, the balance suspension axle, balance shaft end cap assembly, the balance shaft assistant support, between the chassis side rail, form balance suspension pivot pin shaft type captive joint.This heavy goods vehicles equalizing-suspension device, changed the stressed effect situation of balance suspension axle on the whole, and the car load that steel plate spring assembly is born and disperse to the correlated parts transmission to the extrusion stress of vehicle frame inboard, thereby avoid the balance shaft support to greatest extent, the damage of parts such as balance suspension axle, strengthened the whole shock resistance of equalizing-suspension device, comprehensive in-use performance such as endurance life, reduced the balance shaft support from the bolt cracking that connects to ground, the fragmentation of equalizer bearing hub, the generation of situations such as balance suspension axle axle fracture, prolong the service life of equalizing-suspension device, reached the purpose of saving social resources and increasing economic benefit for the car load user.
Description of drawings:
Fig. 1 is the structural representation of a kind of heavy goods vehicles equalizing-suspension device of the utility model.
Fig. 2 is the rotation profile of a kind of heavy goods vehicles equalizing-suspension device of the utility model.
The specific embodiment:
As Fig. 1, shown in Figure 2, a kind of heavy goods vehicles equalizing-suspension device of the utility model is made of balance shaft support 2, balance suspension axle 3, equalizer bearing hub 4 etc., fix a balance shaft assistant support 8 by the chassis side rail directly over balance shaft support 21 near equalizer bearing hub 4 one sides, described balance shaft assistant support 8 is connected with the upper end of a balance shaft end cap assembly 5, the lower end of described balance shaft end cap assembly 5 is fixed on the balance suspension axle 3, forms the utility model equalizing-suspension device.Owing to consider that automobile is when jolting road traveling, can be subjected to the impact of longitudinal force, so adopting the outer end of balance shaft assistant support 8 extends downwards, the mode that the upper end of passing a balance shaft end cap of the partial sum assembly 5 that the outer end of described balance shaft assistant support 8 extends downwards by bearing pin 7 and balance shaft assistant support 8 are fixed near a side of chassis side raiies, effect is best.
Claims (2)
1, a kind of heavy goods vehicles equalizing-suspension device is to be made of balance shaft support, balance suspension axle, equalizer bearing hub, it is characterized in that, fix a balance shaft assistant support by the chassis side rail directly over the balance shaft support near equalizer bearing hub one side, described balance shaft assistant support is connected with the upper end of a balance shaft end cap assembly, and the lower end of described balance shaft end cap assembly is fixed on the balance suspension axle.
2, a kind of heavy goods vehicles equalizing-suspension device according to claim 1 is characterized in that the outer end of described balance shaft assistant support is extended downwards; Pass the upper end and the balance shaft assistant support of a downward balance shaft end cap of the partial sum assembly that extends in outer end of described balance shaft assistant support fixes near a side of chassis side rail by bearing pin.
