The utility model discloses the two-stage that introduces on prior art is sealed: the first level is achieved by arranging a sealing groove and a sealing ring, and the sealing effect is ensured under the action of the pin shaft; the other level is that the end face of the lining is provided with a rubber pad, so that the sealing effect is ensured, and the damping performance is good.
Description
Technical Field
The utility model relates to a steel sheet suspension field, concretely relates to novel energy-concerving and environment-protective car steel sheet suspension, the effectual leaf spring suspension of having solved is lubricated not in place and to the problem of lubricating grease non-protection, still reduces the possibility that produces the abnormal sound simultaneously.
Background
In wheel suspensions of modern motor vehicles, in which different types of springs are used to connect the main vehicle structure to the wheels of the vehicle, in addition to helical springs, leaf springs are often used which extend along the longitudinal axis of the vehicle and generally have a shape which is concave upwards, for example in a parabolic manner, and in addition to leaf springs made of spring steel, leaf springs made of composite materials, for example fibre-reinforced plastics, are sometimes used. At present, it is possible to use a single spring or even a spring assembly comprising two or more springs, at least one of which is connected, usually in a central region, to the shaft to be spring-supported by means of a clamping device.
However, the plate spring suspension in the current market does not adopt a sealing protection measure for the lubricating grease, and the influences of dust, rain, snow and weathering drying and solidification cannot be effectively isolated, so that the effect waste during the lubricating grease filling is caused; meanwhile, the installation mode in the prior art can not avoid rigid contact between the plate spring support and the plate spring, and the lasting mechanical impact not only brings noise, but also causes cracks generated by fatigue stress on the plate spring, thereby affecting the service life.
Disclosure of Invention
According to the problem that the background art provided, the utility model provides a novel energy-concerving and environment-protective car steel sheet suspension solves, and is right next the utility model discloses do and further explain.
A novel energy-saving environment-friendly automobile steel plate suspension comprises a plate spring support, wherein opposite plate spring lifting lugs are arranged on the plate spring support, a plate spring is arranged between the plate spring lifting lugs, a bush is arranged on the plate spring, and the plate spring is fixed on the plate spring lifting lugs through a pin shaft penetrating through the bush; the two ends of the bush are provided with seal grooves, seal rings are arranged in the seal grooves, a seal containing cavity is formed among the bush, the pin shaft and the seal grooves, and a rubber pad is arranged between the end face of the plate spring and the end face gap between the plate spring lifting lugs.
Has the advantages that: compared with the prior art, the utility model discloses the two-stage that introduces on prior art is sealed: the first level is achieved by arranging a sealing groove and a sealing ring, and the sealing effect is ensured under the action of the pin shaft; the other level is that the rubber pad is arranged on the end face of the bushing, so that the sealing effect is guaranteed, the damping performance is good, the whole suspension has a high sealing effect on the sealing of the lubricating grease, the good anti-leakage and environment-friendly effects are achieved, the generation of mechanical impact stress is avoided, and the service life of the suspension is prolonged.
Drawings
FIG. 1: the structure of the utility model is shown schematically;
in the figure: plate spring support 1, leaf spring lug 2, rubber pad 3, round pin axle 4, bush 5, leaf spring 6, seal groove 7, sealing washer 8.
Detailed Description
A specific embodiment of the present invention will be described in detail with reference to fig. 1.
A novel energy-saving environment-friendly automobile steel plate suspension comprises a plate spring support 1 serving as a bearing structure, wherein opposite plate spring lifting lugs 2 are arranged on the plate spring support 1, a plate spring 6 is arranged between the plate spring lifting lugs 2, a bush 5 is arranged on the plate spring 6, and the plate spring 6 is fixed on the plate spring lifting lugs 2 through a pin shaft 4 penetrating through the bush 5; the two ends of the bush 5 are provided with seal grooves 7, seal rings 8 are arranged in the seal grooves 7, a seal containing cavity is formed among the bush 5, the pin shaft 4 and the seal grooves 7, and the built-in lubricating grease is sealed and protected.
A rubber pad 3 is arranged between the end face clearance between the end face of the plate spring 6 and the plate spring lifting lug 2, the rubber pad 3 is tightly pressed between the end face of the plate spring 6 and the plate spring lifting lug 2 under the fastening of the pin shaft 4, and the rubber pad 3 has good sealing performance and good damping performance.
In this embodiment, the width of seal groove 7 is greater than the width side of sealing washer 8, makes things convenient for placing of seal groove 7 to, seal groove 7 distance is 10mm apart from the terminal surface of bush 5, and the degree of depth of seal groove 7 is 2mm, and the section diameter of sealing washer 8 is 2.55mm, and after round pin axle 4 assembly got into bush 5, sealing washer 8 was 0.55mm by round pin axle compression deformation, so obtained the best sealed effect to lubricating grease of effect.
In other embodiments, an oil seal may be used instead of the rubber pad 3, and the effect of ensuring sealing can also be obtained.
To sum up, the utility model discloses the two-stage that introduces on prior art is sealed: the first level is achieved by arranging a sealing groove 7 and a sealing ring 8, and the sealing effect is ensured under the action of a pin shaft; the other level is that the rubber pad 3 is arranged on the end face of the bushing 5, so that the sealing effect is guaranteed, the damping performance is good, the whole suspension has a very high sealing effect on the sealing of lubricating grease, the good anti-leakage and environment-friendly effects are achieved, the generation of mechanical impact stress is avoided, and the service life of the suspension is prolonged.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
