Abstract
An installing and connecting structure for an automobile pedal support body assembly and a brake main cylinder comprises a pedal bottom plate, a left support body, a right support body, a thermal insulation pad, a pedal reinforcing plate and a brake main cylinder and vacuum booster assembly. The pedal bottom plate is provided with a bolt through hole, a casing pipe is welded in the bolt through hole, the thermal insulation pad is provided with a hole matched with a pushing rod assembly of the brake main cylinder and vacuum booster assembly in size and a hole matched with the casing pipe in size, the casing pipe penetrates through the thermal insulation pad to make contact with the pedal reinforcing plate, and a bolt on the brake main cylinder and vacuum booster assembly penetrates through the pedal reinforcing plate and the casing pipe to be fixedly connected with the pedal bottom plate through a nut. The thermal insulation pad does not need to be provided with a large hole matched with the pedal bottom plate in size, the hole only needs to be matched with the pushing rod assembly of the brake main cylinder and vacuum booster assembly in size, the cutting-off area of the thermal insulation pad is reduced, the excessive noise produced by an engine outside an engine room can be effectively prevented from being transmitted to a cab, and the NVH noise performance inside the cab is improved.
Description
Technical field
The present invention relates to car chassis brake system, be specifically related to a kind of mounting structure structure of auto pedal.
Background technology
Along with people are more and more higher to the requirement of car room traveling comfort, in design process, technical personnel is meeting the condition of design strength and function, will improve as far as possible the NVH noiseproof feature of part.Traditional pin pedal assembly is by pedal base plate, left socle body, right support body, stop lamp switch connecting panel assembly, cross connecting plate, front frame connecting panel forms pedal support body assembly by welding manner, and pedal swinging arm assembly is bolted on pedal support body, by flange surface nut, bolt is locked.Referring to Fig. 1, master brake cylinder band vacuum booster assembly 4 is arranged on outside stretcher brace panel 3, and brake pedal unit 1 is arranged in stretcher brace panel 3, and in the middle of brake pedal unit 1 and stretcher brace panel 3, has the heat insulating mattress 2 of 20 millimeters of one decks.Because heat insulating mattress inner structure major part belongs to felt layers, for meeting matching requirements, heat insulating mattress 2 need be urgent at pedal base plate and the rear guarantee nut 5 of vehicle body junction 2-a large area excision, the consequence causing is to make too much the passing in operator's compartment of motor noise outside cabin, in car load NVH performance, preferably in situation, increased the complaint degree of chaufeur to noise.
Summary of the invention
The mounting connection structure that the object of this invention is to provide a kind of automatic pedal stake body assembly and master brake cylinder, reduces the excision area of heat insulating mattress, can effectively prevent too much the passing in operator's compartment of motor noise outside cabin, improves NVH noiseproof feature in operator's compartment.
A mounting connection structure for automatic pedal stake body assembly and master brake cylinder, comprises pedal base plate, left socle body, right support body, heat insulating mattress, stretcher brace panel and master brake cylinder band vacuum booster assembly; Left socle body and right side support welding form stretcher stake body assembly on pedal base plate.On described pedal base plate, there is bolt through-hole, on described bolt through-hole, be welded with sleeve pipe, the hole that has the push-rod assembly size with master brake cylinder band vacuum booster assembly to adapt on described heat insulating mattress, and the hole adapting with sleeve pipe size, described sleeve pipe contacts with stretcher brace panel through heat insulating mattress, and the bolt on master brake cylinder band vacuum booster assembly is connected and fixed by nut and pedal base plate through stretcher brace panel and sleeve pipe.
Compare with original-pack formula formula, the present invention is because the bolt connection location on pedal base plate has welded sleeve pipe, bolt is realized being connected and fixed of pedal base plate and stretcher brace panel by sleeve pipe, so just need on heat insulating mattress, not open the macropore adapting with pedal base plate size, perforate only need to adapt with the push-rod assembly size of master brake cylinder band vacuum booster assembly, therefore reduce the excision area of heat insulating mattress, can effectively prevent too much the passing in operator's compartment of motor noise outside cabin, improve NVH noiseproof feature in operator's compartment, improve the competitive edge of car load.
Accompanying drawing explanation
Fig. 1 is existing car pedals structural representation;
Fig. 2 is car pedals structural representation of the present invention;
Fig. 3 is brake pedal parts schematic diagrams;
wherein:1 stretcher stake body assembly 2 heat insulating mattress 3 stretcher brace panel 4 master brake cylinder band vacuum booster assemblies, 5 nuts, 1-1 pedal base plate 1-2 left socle body 1-3 right side support 1-4 sleeve pipe.
The specific embodiment
With reference to accompanying drawing, now structure of the present invention is further described.
Referring to Fig. 2 and Fig. 3, stretcher stake body group 1 comprises pedal base plate 1-1, left socle body 1-2, right support body 1-3, and left socle body 1-2 and right side support 1-3 are welded on pedal base plate 1-1.For improving the NVH performance of car load, on pedal base plate 1-1, be provided with 4 bolt through-hole 1-1a, at this bolt through-hole 1-1a place, weld 4 sleeve pipe 1-4.On heat insulating mattress 2, have the hole that the push-rod assembly size with master brake cylinder band vacuum booster assembly 4 adapts, and the hole adapting with sleeve pipe 1-4 size.The length 15mm of long sleeve pipe 1-4, length and the sleeve pipe internal-and external diameter of sleeve pipe can suitably lengthen or shorten according to arrangement certainly.
During installation, sleeve pipe 1-4 contacts with stretcher brace panel 3 through heat insulating mattress 2, and the bolt on master brake cylinder band vacuum booster assembly 4 passes stretcher brace panel 3 and sleeve pipe 1-4, and is connected and fixed with pedal base plate 1-1 by nut 5.
Compare the excision area that has reduced heat insulating mattress 2 centers with existing structure, can effectively prevent too much the passing in operator's compartment of motor noise outside cabin, improved NVH noiseproof feature in operator's compartment.
