Abstract
The utility model discloses a novel back pull rod suspension device which comprises an arc-shaped first support frame, an arc-shaped second support frame, a core, rubber main springs and an outer ring. The inner diameter of the first support frame is larger than that of the second support frame, and the first support frame is connected with the second support frame in an integrated mode, and the outer ring is fixedly arranged on the inner side of the first support frame and tightly matched with the first support frame. The core is fixed in the center of the outer ring through the rubber main springs in a vulcanization mode, arc-shaped inner grooves are all arranged at the front end and the rear end of the core, the rubber main springs are distributed in the inner grooves and provided with arc-shaped protruded portions, arc-shaped rubber striking blocks are arranged in a vulcanization mode on the inner side of the outer ring directly opposite to the arc-shaped protruded portions of the rubber main springs, and the linear distance between the arc-shaped protruded portions of the rubber main springs and the rubber striking blocks is 2-3millimeters. The novel back pull rod suspension device has the advantages that shaking when a car is in idle state is reduced, and abnormal sound when the car is in the idle state is not produced.
Description
Technical field
The utility model relates to a kind of engine assembly technology that suspends, and especially relates to a kind of novel back stay and suspends.
Background technology
Generally suspend on car and the light bus at present and consider that the engine assembly with 3 layouts and 4 layouts suspends, suspend about 3 layouts suspend and generally comprise to suspend with a back stay, suspending about 4 layouts suspend and generally comprise suspends with front and back.3 layouts general vehicle that the dynamic assembly discharge capacity is little, moment of torsion is little that is used for that suspends, the suspend power that can bear of back stay is relatively little like this, and 4 layouts suspend generally for the vehicle that the dynamic assembly discharge capacity is large, moment of torsion is large, and the power of bearing is shared to front and back and being suspended.The layout that suspends at present usually can be subject to the space constraint of vehicle body and dynamic assembly; even the vehicle that sometimes the dynamic assembly discharge capacity is large, moment of torsion is large also has to suspend with 3 layouts; when automobile is treated speed, the vibration that driving engine produces and noise all will be suspended by back stay and bear.Back stay suspends and will treat fast operating mode range in stiffness design in linear portion rigidity at present, and rigidity is difficult to meet the demands, so that can produce stronger shake when automobile is treated speed, and can produce abnormal sound, and strength at repeated alternation is difficult to guarantee.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of automobile that can reduce and treats speed shake, and the novel back stay that can not produce abnormal sound when automobile is treated speed suspends.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of novel back stay suspends, the first support that comprises circular arc, the second support of circular arc, fuse, rubber spring and outer ring, the internal diameter of described the first support connects greater than described the second support and both one, described outer ring is fixedly installed on the inboard of described the first support and closely cooperates with described the first support, described fuse is fixed on center, described outer ring by described rubber spring sulfuration, the front-end and back-end of described fuse are provided with the inner groovy of arc, described rubber spring is distributed in the described inner groovy and has arc-shaped convex section, the arc-shaped convex section of described rubber spring over against the inboard, outer ring on sulfuration the rubber collision block of circular arc is arranged, the straight-line distance between the arc-shaped convex section of described rubber spring and the described rubber collision block is 2-3mm.
The material of described the first support, described the second support is and draws aluminium 6061-T6.
Compared with prior art, the utility model has the advantage of the inner groovy that is provided with arc by the front-end and back-end at fuse, rubber spring is distributed in the inner groovy and has arc-shaped convex section, the arc-shaped convex section of rubber spring over against the inboard, outer ring on sulfuration the rubber collision block of circular arc is arranged, arc-shaped convex section and the straight-line distance between the rubber collision block of rubber spring are 2-3mm, rubber spring and rubber collision block directly hit together when automobile is treated speed on the one hand, go to compensate rubber spring rigidity by rubber collision block rigidity, thereby rigidity requirement when satisfying automobile and treating speed, the displacement of rubber spring is subject to the restriction of rubber collision block on the other hand, the tension and compression stress of rubber spring is just little like this, strength at repeated alternation strengthens, treat the speed shake thereby can reduce automobile, and when automobile is treated speed, can not produce abnormal sound.
Description of drawings
Fig. 1 is the cutaway view of the utility model vertical direction;
Fig. 2 is the cutaway view of the utility model horizontal direction.
The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, a kind of novel back stay suspends, the first support 1 that comprises circular arc, the second support 2 of circular arc, fuse 3, rubber spring 4 and outer ring 5, the internal diameter of the first support 2 connects greater than the second support 2 and both one, outer ring 5 is fixedly installed on the inboard of the first support 1 and closely cooperates with the first support 1, described fuse 3 is fixed on 5 centers, outer ring by rubber spring 4 sulfurations, the front-end and back-end of fuse 3 are provided with the inner groovy of arc, rubber spring 4 is distributed in the inner groovy and has arc-shaped convex section 41, the arc-shaped convex section 41 of rubber spring 4 over against the inboard upper sulfuration in outer ring 5 the rubber collision blocks 6 of circular arc are arranged, arc-shaped convex section 41 and the straight-line distance between the rubber collision block 6 of rubber spring 4 are 2-3mm.
In the above-mentioned specific embodiment, the material of the first support 1, the second support 2 can be for drawing aluminium 6061-T6.
Claims (2)
1. a novel back stay suspends, the first support that comprises circular arc, the second support of circular arc, fuse, rubber spring and outer ring, the internal diameter of described the first support connects greater than described the second support and both one, described outer ring is fixedly installed on the inboard of described the first support and closely cooperates with described the first support, described fuse is fixed on center, described outer ring by described rubber spring sulfuration, it is characterized in that the front-end and back-end of described fuse are provided with the inner groovy of arc, described rubber spring is distributed in the described inner groovy and has arc-shaped convex section, the arc-shaped convex section of described rubber spring over against the inboard, outer ring on sulfuration the rubber collision block of circular arc is arranged, the straight-line distance between the arc-shaped convex section of described rubber spring and the described rubber collision block is 2-3mm.
