Abstract
The utility model discloses a hydraulic bushing with a split-type runner, which comprise an outer ring, a main spring, a skeleton and an annular runner plate with a gap, wherein the outer ring is sleeved on the main spring. The hydraulic bushing with the split-type runner is characterized in that the main spring and the skeleton are connected into a whole through the vulcanization of rubber; the annular runner plate comprises two arc iron plates which are horizontally spliced; the annular runner plate annularly covers the main spring and is arranged between the main spring and the outer ring; a hydraulic bushing runner in an annular direction is formed on the outer surface of the runner plate; and one runner opening getting through in the radial direction is formed at each of two ends of the hydraulic bushing runner on the runner plate. The hydraulic bushing with the split-type runner has the advantage of outstanding damping adjustability, leak tightness and stability, and can improve the NVH performance of the whole vehicle.
Description
Technical field
The utility model relates to a kind of hydraulic bushing, particularly a kind of hydraulic bushing with split type runner.
Background technique
Common hydraulic bushing runner is general in the majority through the rubber integrated vulcanizing with main spring, and runner performance adjustability is relatively poor, affects car load NVH performance (annotate: NVH refers to noise, vibration and sound vibration roughness) because the runner damping characteristic is bad; In addition, common hydraulic bushing sealability is good not, easily causes the phenomenon of leakage after the entrucking, thereby greatly affects the performance of hydraulic bushing.
Summary of the invention
Technical problem to be solved in the utility model is: for the deficiencies in the prior art, provide a kind of hydraulic bushing with split type runner, this hydraulic bushing runner damping adjustability, sealing, good stability.
The utility model solves the problems of the technologies described above the technological scheme that adopts: a kind of hydraulic bushing with split type runner, comprise the outer ring, main spring, skeleton and notched ring runner plate, described outer ring sleeve is located on the described main spring, described main spring and described skeleton are connected as a single entity by the vulcanization of rubber, described runner plate is spliced by two circular arc iron plate levels, described runner plate latch closure is on the described main spring and between described main spring and described outer ring, described runner plate outer surface is provided with the hydraulic bushing runner of hoop, has a runner mouth of radially getting through on the described runner plate at the two ends of described hydraulic bushing runner.
Preferably, the sectional shape of described hydraulic bushing runner is circular arc.
Preferably, the internal surface of described outer ring is provided with the ring packing muscle group of the projection that distributes vertically with predetermined distance.
Preferably, described sealed muscle group is four groups, and every group is enclosed compact arranged ring packing muscle by two and form.
Preferably, described sealed muscle group is connected as a single entity by the vulcanization of rubber and described outer ring.
Preferably, described sealed muscle group closely links to each other with described main spring with described runner plate by diameter reducing process.
Compared with prior art, the utility model has the advantage of: the utility model hydraulic bushing is owing to the structure of the split type runner that has adopted runner and main spring to assemble respectively, during use, liquid under liquid by can and be sealed in the utility model hydraulic bushing, when automobile is subjected to all size amplitude excitations, liquid is through this Split type hydraulic circulated to-and-fro motion, because of the effect of runner damping characteristic, but thereby effective attenuation vibration, the long-pending size of cross section of fluid channel is adjustable when design, hydraulic bushing runner damping adjustability is good, has improved car load NVH performance; Owing to having and the many group sealed muscle of lining outer ring through the rubber integrated vulcanizing, runner outside formation multi-layer sealed, effectively avoided the phenomenon of leakage of lining, hydraulic bushing good airproof performance; In addition, main spring and skeleton are connected as a single entity by the vulcanization of rubber, can regulate as required the area of contact size of skeleton and main spring in the practical application, not only improve the static stiffness of hydraulic bushing, and runner plate played supporting effect, the good stability of the utility model hydraulic bushing.

Fig. 2 is the utility model embodiment's front section view.
Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, a kind of hydraulic bushing with split type runner, comprise outer ring 1, main spring 2, skeleton 3 and the notched ring runner plate 4 that is spliced by two circular arc iron plate levels, main spring 2 and skeleton 3 are connected as a single entity by the vulcanization of rubber, outer ring 1 is set on the main spring 2, runner plate 4 latch closures are on the main spring 2 and between main spring 2 and outer ring 1, runner plate 4 outer surfaces are provided with the hydraulic bushing runner 5 of hoop, have a runner mouth 6 of radially getting through on the runner plate 4 at the two ends of hydraulic bushing runner 5, the internal surface of outer ring 1 is provided with and the ring packing muscle group 7 of outer ring 1 through the projection that distributes vertically with predetermined distance of rubber integrated vulcanizing.
Runner plate 4 is spliced by two circular arc iron plate levels, is convenient to the latch closure of runner plate 4 on main spring 2 and installs, and is conducive to the close contact of runner plate 4 and main spring 2.
In the present embodiment, the sectional shape of hydraulic bushing runner 5 can be circular arc; The quantity of sealed muscle group 7 can be four groups, and every group is enclosed compact arranged ring packing muscle by two and form; Sealing effect when adopting diameter reducing process that sealed muscle group 7 is closely linked to each other with main spring 2 with runner plate 4 is better.
During use, liquid is sealed in the utility model hydraulic bushing, when automobile is subjected to all size amplitude excitations, liquid is entered hydraulic bushing runner 5 from a side hydraulic pressure cavity 8 through this effluent road junction 6 repeatedly, flows out hydraulic bushing runners 5 and is pressed in the opposite side hydraulic pressure cavity 9 through opposite side runner mouth 6, and liquid so moves in circles mobile, because of the 5 damping characteristic effects of hydraulic bushing runner, but the effective attenuation vibration, and runner damping adjustability is good, has improved car load NVH performance.In addition, because the internal surface of outer ring 1 is provided with the ring packing muscle group 7 of the projection that distributes vertically with predetermined distance, effectively avoided the phenomenon of leakage of lining, good sealing effect, the sealing effect when especially adopting diameter reducing process that sealed muscle group 7 is closely linked to each other with main spring 2 with runner plate 4 is better.
In addition to the implementation, the utility model hydraulic bushing runner 5 can also adopt other structures, and for example except circular section, the cross section of hydraulic bushing runner 5 can be V-arrangement, square or other shapes; The quantity of sealed muscle group 7 also is not limited to four groups.Such conversion all drops within the protection domain of the present utility model.
