Description
(1) technical field
The utility model relates to automobile rubber plinth and flat spring bracket assembly technical field, particularly a kind of sliding type heavy-duty car rubber support saddle and flat spring bracket assembly that is applicable to heavy engineering vehicle balance rear-pendant.
(2) background technology
The structure majority of conventional heavy-duty automobile balance rear suspension is the whole machine balancing axle, and last lower thrust rod is straight-bar, the damping of leaf spring one-level, and terminal and flat spring bracket sliding block joint supports.Because last lower thrust rod is a straight-bar,,, need to rely on the side travel of leaf spring, guide plate and flat spring bracket restriction bridge in order to prevent the drive axle left and right displacement so automobile located lateral function is relatively poor.Steyr conventional panels spring bracket is semiclosed form, has increased the side limit function afterwards, and flat spring bracket becomes the rectangular closed frame structure, assembles the vehicle ride comfort of this flat spring bracket structure, and stability is all relatively poor, has been tending towards superseded now.
The individually balanced axle of the general assembling of now common balance rear-pendant, V-type propelling rod location, elastic vibration clamper is generally steel spring and adds rubber plinth.Owing to have steel spring and the damping of rubber plinth two-stage, so the ride comfort of vehicle is better.The basic structure form of rubber plinth is that two end plates are arranged up and down, and there is the rubber bodies of circle, rectangle or other shapes the centre, the interior uniform multi-disc sheetmetal parallel, the space up and down of rubber bodies.Four jiaos of bottom plates are porose captives joint with axle housing, and upper head plate is connected with leaf spring, and connection mode can be divided into two kinds of bolted connection formula and sliding types substantially.
The rubber plinth of bolted connection formula is exactly to make the gap in a slice of leaf spring and two centres, inserts strap in the gap, and Qi Sijiao is porose, and the correspondence position of rubber plinth upper head plate is shaped on 4 screw threads or hole equally.During assembling, end plate and clamping plate are by bolted connection, and every end uses 4 bolts, and totally 8, this has just realized captiveing joint of leaf spring and rubber plinth.The rubber plinth another one feature of this structure is that up and down there is hole at end plate and rubber bodies center, be installed with center bolt in the hole, bolt cap and nut block upper and lower end plate respectively, when vehicle bridge and vehicle frame are done away from motion, thereby center bolt is subjected to pulling force is restricted the maximum elongation amount of rubber plinth, thus limited axle housing and vehicle frame away from motion.
Shortcoming of the rubber plinth of this structure is the existence owing to tie bolt, and it is bigger that strap and upper head plate are compelled to do, and this has just increased the probability of interfering with tire, vehicle frame; Another shortcoming is that 8 above-mentioned bolts are difficult to Assembly ﹠Disassembly relatively, has increased the time and the expense of assembling and maintenance, bolt is also necessarily required correct screw-down torque, otherwise ease of connection loses efficacy; At last because the existence of rubber plinth center bolt, when automobile for a long time under certain relatively poor operating mode during operation, center bolt fractures easily and causes rubber plinth to lose efficacy.
The arch or the arc shape of both sides bending before and after the upper head plate of the rubber plinth of sliding type is made cancelled connecting thread or connecting bore with leaf spring, owing to no longer bear pulling force, so cancelled center bolt, all the other structures and first kind are basic identical.First and second no gap of leaf spring.
The advantage of this rubber plinth is owing to cancelled tie bolt with leaf spring, so assembling and keep in repair comparatively simple and fast.But shortcoming is that rubber plinth can not limit the disengaging movement of axle housing and vehicle frame owing to cancelled center bolt, so must increase Anchoring chain, this also makes integral structure comparatively complicated.
Be illustrated in figure 1 as nearest certain car company and disclose a kind of newer rubber plinth, outstanding feature is exactly the flat spring bracket structure that its upper head plate has become rectangular closed frame.During assembling, be fixed on the axle housing with the bottom plate of bolt earlier, then the leaf spring end gaps directly inserted in the upper head plate of flat spring bracket structure rubber plinth.This rubber plinth had both made that assembling was comparatively simple, again owing to there being center bolt, so kept the lower limit function.But still owing to center bolt fractures easily, so rubber plinth lost efficacy easily.
Above-mentioned three kinds of rubber plinths all exist a common shortcoming can not bear transverse force exactly, when vehicle (particularly engineering truck) load is big, road conditions are relatively poor, turn to when comparatively frequent, the V-type propelling rod is stressed abominable, be easy to lose efficacy, V bar inefficacy rear driving axle and vehicle frame just can't be located in the horizontal, and vehicle can't continue to travel.Therefore must under heavy duty, repair, do so at first for relatively danger of maintainer, secondly owing to operation outside the station can't guarantee the automotive servicing quality.
(3) summary of the invention
The utility model is in order to solve the problem that can not bear transverse force, maintenance inconvenience that above prior art exists, provide a kind of and not only can guarantee original effectiveness in vibration suppression, and optimized the stressed of original rubber plinth, improved the service life of rubber plinth, simple equally aspect assembling and maintenance, convenient and practical heavy-duty car rubber support saddle and flat spring bracket assembly.
The utility model is realized by following measure: a kind of heavy-duty car rubber support saddle and flat spring bracket assembly, comprise rubber plinth, flat spring bracket, it is characterized in that: described flat spring bracket is sealing or semiclosed framed structure, and rubber plinth is installed in the cavity of framed structure.
The utility model rubber plinth comprise upper head plate, bottom plate and be positioned at upper head plate and bottom plate in the middle of rubber bodies, the upper head plate upper surface is circular arc, bottom plate is connected with flat spring bracket.
Rubber bodies described in the utility model cross section is rectangular, and fore-and-aft direction is up-small and down-big to be trapezoidal, and there are several layers of sheetmetal that is parallel to each other the centre.
The utility model rubber plinth also comprises several intermediate plates between upper head plate, bottom plate, and the three is parallel curved surface, and is one by the rubber bodies sulfuration.
Both sides are provided with downward flange before and after the upper head plate described in the utility model, and both sides are provided with flange upwards before and after the bottom plate.
Both sides are provided with flange upwards before and after the upper head plate described in the utility model, and both sides are provided with downward flange before and after the bottom plate.
