Abstract
The utility model relates to a pneumatic braking general pump assembly for an automobile, solving the shortages that in the prior art, the brake does not works, and the reliability and the safety of driving the automobile are threatened which are frequently the origin of traffic accidents. The utility model is characterized in that on the basis of the pneumatic braking general pump assemblies of a passenger automobile and a goods automobile with a Jiefang and a Dongfeng automobile chassises and a special purpose vehicle, and the sizes of a circular lug boss, a valve, a tail seat and an inner circular lug boss in a top barrel, a jib, and an upper seat are changed; the structures of other components are not changed to achieve the purpose, and the brake is absolutely reliable. The utility model can be used for the passenger automobile and the goods automobile with the Jiefang and the Dongfeng automobile chassises and the special purpose vehicle.
Description
The utility model relates to the parts of vehicle braking control system, particularly uses the vapour master brake cylinder assembly of visitor, lorry and the special vehicle of Jiefang brand, Dongfeng brand car chassis.
Use the vapour master brake cylinder assembly of visitor, lorry and the special vehicle of Jiefang brand, Dongfeng brand car chassis in the prior art, its objective is this car in travelling is checked.The structure of Jiefang brand chassis Shanghai Automobile Factory master brake cylinder assembly is: minor valve places in the base, and big valve places in the seat, and the top tube is gone up cover one spring, is fixed and is placed in the seat of honour by spring cover, and loam cake connects the seat of honour, middle, base successively; The structure of chassis, Dongfeng brand Shanghai Automobile Factory master brake cylinder assembly is: ball places the interior tappet that also connects successively of the nest in the loam cake, seal cover cap, left and right sides tailstock is connected with loam cake at grade, and the two ends of spring are sutaining valve gate seat and valve respectively, valve places respectively in the valve seat, and valve seat screws in the tailstock.Its weak point is since in therebetween the top tube, tappet, the seat of honour design of boss platform and valve, the interior boss platform of tailstock unreasonable, cause the brake failure when heavy duty of the type automobile, the reliability of driving, safety are subjected to threatening greatly and often are the causes of traffic accident.As evening on the 27th August in 1997 the Guizhou TV news broadcast the traffic accident that collides of five cars, promptly be because of not good enough wine of dongfeng truck brake.
The purpose of this utility model is to solve above-mentioned weak point of the prior art, and a kind of automobile vapour master brake cylinder assembly that can guarantee that the above-mentioned type braking automobile is reliable, stable, safe is provided.
Technical solution of the present utility model is: on the basis of the vapour master brake cylinder assembly that has the visitor, lorry and the special vehicle that use Jiefang brand, Dongfeng brand car chassis now, only the actual size of boss platform in boss platform, valve and the tailstock in therebetween top tube, tappet, the seat of honour is changed, the structure of all the other parts does not all change and promptly reaches purpose.
The advantage that the utility model is had compared to existing technology is: though only the physical dimension of these several parts is changed, but facts have proved that brake is absolute reliable, both be under the state of overload, stopped therefore and the traffic accident that causes, reduced the labour intensity of chaufeur, the glancing impact trailing wheel has reduced the wearing and tearing of brake facing prior to front-wheel.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the integral structure scheme drawing after improve with valve on the east wind chassis.
Fig. 2 is the integral structure scheme drawing of former east wind chassis with valve.
Fig. 3 is the integral structure scheme drawing after improve with tappet on the east wind chassis.
Fig. 4 is the integral structure scheme drawing of former east wind chassis with tappet.
Fig. 5 is the integral structure scheme drawing of east wind chassis with tailstock.The utility model is that the interior boss platform on it 3 is shortened.
Fig. 6 is for liberating the integral structure scheme drawing after improve with tappet on the chassis.
Fig. 7 is the integral structure scheme drawing of former liberation chassis with tappet.
Fig. 8 is the integral structure scheme drawing of liberation chassis with the seat of honour.The utility model is that the interior boss platform on it 2 is shortened.
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment: for the vapour master brake cylinder assembly of visitor, lorry and the special vehicle of Jiefang brand car chassis, add a flat gasket in the lower end of top tube inner spring, to increase the stress that gives of spring.Boss platform in the tappet 4 and the seat of honour 5 is shortened; For the vapour master brake cylinder assembly of visitor, lorry and the special vehicle of Dongfeng brand car chassis, the boss on the tappet 2 is shortened, the hole on the tappet 2 is deepened.The boss 3 of circle in boss on the valve 1 and the tailstock is shortened.Like this it is assembled by the prior art former state and get final product.The automotive use of the visitor of available Jiefang brand, Dongfeng brand car chassis, lorry and special vehicle.
Claims (2)
1, a kind of automobile vapour master brake cylinder assembly, minor valve places in the base, big valve places in the seat, the top tube is gone up cover one spring, fix and place in the seat of honour by spring cover, loam cake connects the seat of honour, middle seat, base successively, it is characterized in that adding a packing ring in the lower end of top tube inner spring, and boss platform 5 shortens in the tappet 4 and the seat of honour.
2, according to the automobile vapour master brake cylinder assembly described in the claim 1, it is characterized in that ball places in the nest of loam cake, and connect tappet, seal cover cap successively, left and right sides tailstock is connected with loam cake at grade, and the two ends of spring are sutaining valve gate seat and valve respectively, and valve places in the valve seat respectively, valve seat screws in the tailstock, boss on the tappet 2 shortens, and deepen in the hole on the tappet 2, and the boss 3 of circle shortens in boss on the valve 1 and the tailstock.
