Abstract
A kind of mud guard props up seat assembly, comprise mud guard bearing, steel pipe, mud guard bearing comprises the vehicle frame fixed support, upper bracket, the lower bracket that connect successively from top to bottom, vehicle frame fixed support, upper bracket, lower bracket are all sheet stamping member, and being provided with rubber mount between vehicle frame fixed support, upper bracket, steel pipe is matched with the inwall of upper bracket, lower bracket by its outside sheathed rubber bush.The design not only improves manufacture and assembly process process, and improves effectiveness in vibration suppression.
Description
Technical field
The utility model relates to commercial vehicle/comm..vehicle parts technical field, is specifically related to a kind of mud guard and props up seat assembly, is applicable to improve manufacture and assembly process process, raising effectiveness in vibration suppression.
Background technology
At present, the installation form of fender configuration conventional on commercial vehicle/comm..vehicle mostly is mud guard bearing and directly compresses round steel pipe, forms rigid contact.On the one hand, mud guard bearing is generally steel casting, and quality is comparatively large, does not therefore meet the designing requirement of car load weight-saving; On the other hand, in installation process, along with the increase of the urgent power of bolt, mud guard bearing extruding round steel pipe can destroy mating surfaces paint, and vehicle long run exposes to the sun and rain, and cast steel support and round steel pipe easily corrosion occur, and service life reduces greatly; Meanwhile, mud guard prop up seat assembly compress round steel pipe be rigidly connected.Car load travels road conditions complexity, and especially mountain area is jolted seriously, and mud guard vibration is comparatively large, and support easily fatigue cracking occurs, and is rigidly connected and easily causes mud guard loose or dislocation, there is serious potential safety hazard.
Chinese patent: Authorization Notice No. is CN203793441U, authorized announcement date is that the utility model patent on August 27th, 2014 discloses a kind of medium and heavy truck mud flap fixed mount assembly, comprise metal support and metal steel pipe, metal steel pipe one end outer wall sulfuration last layer rubber, metal support inwall scribbles one deck preventing rubber adhesive film, metal steel pipe vulcanised rubber layer position elastic conjunction is plugged in metal support.Although the intensity that the vibration that this utility model significantly reduces bearing is transmitted to metal cantilever, decrease the fatigue of bearing and metal steel pipe junction, thus extend its service life, but still there is following defect:
In this utility model, metal support is one-piece construction, and adopt interference fit with metal steel pipe, therefore to the fine limit work of itself and metal steel pipe contact surface and matching requirements higher, simultaneously, the technological requirement adding coat with rubber protection adhesive film at metallic steel tube-surface polysulphide rubbers, metal support inwall is also higher, therefore, its manufacture and assembly technology comparatively complicated.
Summary of the invention
The purpose of this utility model overcomes the manufacture of existing structure existence and the problem of assembly technology complexity, provides a kind of mud guard that can improve manufacture and assembly process process to prop up seat assembly.
For realizing above object, the technical solution of the utility model is as follows:
A kind of mud guard props up seat assembly, the steel pipe comprising mud guard bearing and be mated;
Described mud guard bearing comprises the vehicle frame fixed support, upper bracket, the lower bracket that connect successively from top to bottom, be provided with rubber mount between described vehicle frame fixed support, upper bracket, steel pipe is matched with the inwall of upper bracket, lower bracket by its outside sheathed rubber bush.
Described vehicle frame fixed support comprises a connecting panel connected vertically, No. two connecting panels, and a described connecting panel is fixedly connected with vehicle frame, and No. two connecting panels are fixedly connected with upper bracket, and rubber bush is provided with positive stop lug boss away from one end of a connecting panel.
Described vehicle frame fixed support, upper bracket, lower bracket are all sheet stamping member.
Compared with prior art, the beneficial effects of the utility model are:
1, a kind of mud guard of the utility model props up mud guard bearing in seat assembly and comprises the vehicle frame fixed support, upper bracket, the lower bracket that connect successively from top to bottom, and be provided with rubber mount between vehicle frame fixed support, upper bracket, steel pipe is matched with the inwall of upper bracket, lower bracket by its outside sheathed rubber bush, on the one hand, mud guard bearing is divided into upper and lower split structure by the design, upper and lower structure all can one-shot forming, without the need to fine limit work, and only need during assembling to adopt common bolt mounting means, manufacture and assembly process process better; On the other hand; the design protects the paint of upper and lower support and steel pipe mating surfaces from assembling squeeze and destroy by rubber bush; reduce support and steel pipe corrosion risk; improve its service life; effectively can carry out vibration isolation, vibration damping to mud guard bearing by rubber mount and rubber bush, reduce the risk of its fatigue cracking, solve the potential safety hazard of the easy loose or dislocation of mud guard; the technique of this vibration damping form more easily realizes, and effect is more excellent.Therefore, the utility model not only improves manufacture and assembly process process, and improves effectiveness in vibration suppression.
2, a kind of mud guard of the utility model props up in seat assembly and rubber bush is provided with positive stop lug boss away from one end of a connecting panel, and this positive stop lug boss can realize the axial location to rubber bush in fitting process, prevents its axial motion.Therefore, the utility model is conducive to the assembling of a seat assembly.
3, a kind of mud guard of the utility model props up vehicle frame fixed support, upper bracket, lower bracket in seat assembly is all sheet stamping member, and its quality is lighter, cost is also lower.Therefore, the utility model alleviates quality, reduces cost.
