Abstract
The utility model discloses an auxiliary supporting structure of a retarder. The auxiliary supporting structure is strong in operability, simple and convenient to install and simple in process. The auxiliary supporting structure comprises a retarder hung cross beam assembly, wherein two adjustable knuckle bearing hinge assemblies are fixed on the retarder hung cross beam assembly and are fixed on two sides above a retarder assembly through a retarder hoisting connection support. During installation, if the retarder moves slightly back and forth due to changing of engine models and gearbox models, height change can be complemented through length stretching and contracting of the adjustable knuckle bearing hinge assemblies, and the front-and-back and the left-and-right deviation can be complemented through ball joint rotating of the adjustable knuckle bearing hinge assemblies. When the front-and-back position movement of the retarder is large, a new vacant position is added on a vehicle frame longitudinal beam to lead a shock absorber to be arranged at the appropriate position to meet installation requirements. The auxiliary supporting structure has strong generality, is convenient to mount and demount, and greatly improves production efficiency.
Description
Technical field
The utility model relates to a kind of auxiliary support structure, is specifically related to a kind of retarder auxiliary support structure.Belong to automobile manufacturing field.
Background technology
Motor passenger vehicle is as a kind of vehicle of public's go off daily, its safety, economy and the feature of environmental protection more and more receive people's concern, auxiliary braking system is also more and more paid attention in new national standard, in new " self-propelled vehicle safe and technical specification " GB7258-2012 7.5 auxiliary braking clears " vehicle commander more than or equal to the lorry of 12000kg and special Operation Van, all hazardous material transportation cars, should equip retarder or other complemental brake systems greater than the passenger vehicle (being that the vehicle commander is greater than 8m to special-purpose school bus) of 9m, total mass.The performance requriements of complemental brake system is because testing by II type or II A type that GB12676 stipulates automobile." my company finds by test, passenger vehicle can only be used retarder by II type or II A type experiment complemental brake system that GB12676 stipulates, and engine exhaust and brake can't be by the experiment of GB12676.
Retarder is installed on passenger vehicle and truck at present two kinds of current vortex retarder and hydrodynamic retarders, current vortex retarder is taken product as the leading factor in present Chinese market, but its shortcoming is arranged also, be that quality is large, nearly 150kg left and right, when being arranged on change speed gear box, dynamic assembly is increased more moment of flexure, engine mounting is supported the impact in service life very large.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of retarder auxiliary support structure is provided, strong operability, and simple installation, technique is simple.
For achieving the above object, the utility model adopts following technical proposals:
A kind of retarder auxiliary support structure, comprise retarder lifting cross beam assembly, be fixed with two on described retarder lifting cross beam assembly and can regulate oscillating bearing hinge assembly, the described oscillating bearing hinge assembly of regulating lifts by retarder the both sides, top that connection bracket is fixed to the retarder assembly.
Be provided with the retarder cleading between described retarder lifting connection bracket and retarder assembly.
The two ends of described retarder lifting cross beam assembly are connected with respectively bumper, and described bumper is respectively fixed on chassis side rail.
Describedly regulate the bearing seat that oscillating bearing hinge assembly comprises adjust bar and two ends, described bearing seat is provided with tapped bore, and the two ends of adjust bar are provided with the screw thread that matches with tapped bore, screw in the adjustable in length of tapped bore.
Be provided with jam nut between described bearing seat and adjust bar.
The outside of described bearing seat is provided with the hollow ball that can rotate freely, and hollow ball is pressed on bearing seat by trim ring.
Installation method of the present utility model is as follows:
Bumper is arranged on chassis side rail by bolt, retarder lifting cross beam assembly uses bolt to be arranged on bumper, can regulate oscillating bearing hinge assembly uses bolt, nut and bullet pad to be connected with retarder lifting cross beam assembly, retarder is lifted connection bracket use bolt, nut and bullet pad and can regulate oscillating bearing hinge assembly and is connected, the use bolt lifts retarder on connection bracket, retarder cleading installation retarder assembly.
The using method that can regulate oscillating bearing hinge assembly is: hollow ball is pressed on bearing seat by trim ring, hollow ball can be rotated freely; Adjust bar is connected with the bearing seat at two ends, the tapped bore that bearing seat is connected with adjust bar has certain length, regulate by the length that screws in adjust bar the length that can regulate oscillating bearing hinge assembly, locked with jam nut, adapt to this height difference and installation error that different slowing down speed of engine are installed.
If when mounted because the replacing of engine type, the replacing of change speed gear box model etc. causes the front and back fine motion of retarder position, can stretch to make up variation on height by what can regulate oscillating bearing hinge assembly length, by the ball that can regulate oscillating bearing hinge assembly connect rotation make up before and after and the deviation of left and right.Increasing new room if front and back position moves when larger at chassis side rail installs bumper to make it in place to adapt to needs is installed.
The beneficial effects of the utility model are, the utility model possesses very strong commonality, and easy installation and removal has greatly improved production efficiency.
