Abstract
The utility model discloses a through joint for a hydraulic system, a hydraulic system and an automobile with a hydraulic system. The through joint for the hydraulic system comprises a joint body and a rubber washer, wherein the rubber washer is sleeved around the joint body. As the rubber washer is used for replacing a metal washer, the through joint for the hydraulic system is convenient to maintain, can reduce maintenance cost and also meet the requirement of sealing performance; and more importantly, as the rubber washer has good plasticity, the through joint for the hydraulic system can be repeatedly used, and the sealing effect is not influenced.
Description
Technical field
The utility model relates to hydraulic system linkage structure technology, relates in particular to a kind of hydraulic system straight coupling, hydraulic system and automobile thereof.
Background technique
Generally include steering oil pipe and steering pump in the existing car hydraulics, connect by straight coupling between the two.
In order to guarantee to be tightly connected, prior art adopts the form that metal washer is set between straight coupling and steering oil pipe and steering pump to seal.So-called straight coupling, it comprises joint body, and joint body inside is formed with through hole, and the middle part of joint body has the projection of tightening, and the two ends that tighten projection are formed with outside thread respectively.The fit that straight coupling is concrete, around when assembling is enclosed within two metal washers joint body, then with joint body respectively with steering oil pipe and steering pump on internal thread be tightened, seal from both sides extrusion metal packing ring.
But there is following defective in above-mentioned encapsulation scheme: because sealing material is a metal washer, cost is higher; Can be out of shape after metal washer is squeezed, if need secondary to use, because the distortion of metal washer can't recover, cause its sealing effect bad after dismounting, fluid seepage phenomenon is general.
The model utility content
The utility model provides a kind of hydraulic system with straight coupling, hydraulic system and automobile thereof, to reduce product cost, optimizes sealing effect.
The utility model embodiment provides a kind of hydraulic system straight coupling, comprises joint body, wherein, also comprises: rubber washer, described rubber washer be set in described joint body around.
Aforesaid hydraulic system straight coupling, preferably: the protruding both sides that tighten of described joint body are provided with the groove that is used for ccontaining described rubber washer.
Aforesaid hydraulic system straight coupling, preferably: the thickness of described rubber washer from inside to outside increases gradually.
The utility model also provides a kind of hydraulic system, comprises steering oil pipe and steerig pump, and wherein: also comprise hydraulic system straight coupling provided by the utility model, the two ends of described straight coupling tighten with steerig pump with steering oil pipe respectively and are connected.
The utility model also provides a kind of automobile, wherein: comprise hydraulic system provided by the utility model.
Hydraulic system usefulness straight coupling, hydraulic system and automobile thereof that the utility model provides owing to adopted rubber washer, have reduced cost, and rubber washer can be used as the annex assembly supply of straight coupling, installation and maintenance and repair convenience.In addition, rubber washer plasticity is good, and is reusable, and do not influence sealing effect, fluid seepage phenomenon when having avoided the metal gasket secondary to use.

Embodiment
For the purpose, technological scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The hydraulic system that Fig. 1 provides for the utility model embodiment plan view of straight coupling; The hydraulic system that Fig. 2 provides for the utility model embodiment left view of straight coupling; The hydraulic system that Fig. 3 provides for the utility model embodiment partial enlarged drawing of straight coupling.From Fig. 1～3 as can be known, this straight coupling comprises joint body 2, is formed with on the joint body 2 to tighten projection 6, and the port shape of the inner penetration hole of this straight coupling can design arbitrarily according to the shape of both sides link.This straight coupling also comprises rubber washer 1, this rubber washer 1 be set in joint body 2 around, be specially: rubber washer 1 is close to and tightens projection 6 two ends and place.
On the basis of technique scheme, preferably protruding 6 both sides that tighten of this joint body 2 are provided with the groove 3 that is used for ccontaining rubber washer 1.By this groove 3 is set, make that the position of rubber washer 1 is easier to be fixing.The position of groove 3 as shown in fig. 1.Rubber washer 1 can partially or completely be embedded in the groove 3.
Rubber washer plasticity is good, and its diameter can be identical or more smaller than it with the externally threaded diameter in joint body two ends, and rubber washer may be stuck in screw thread and tightens between the projection, can landing, thereby rubber washer can be used as the annex assembly supply of straight coupling, and is easy to maintenance, and cost is low.When straight coupling and steerig pump and steering oil pipe are installed, rubber washer need not be installed again, directly steerig pump and steering oil pipe installation be got final product, can simplify installation process.In addition, rubber washer plasticity is good, and is reusable, and secondary can increase its amount of deformation by tightening bolt when using.Thereby guarantee that sealing effect is unaffected, fluid seepage phenomenon when having avoided the metal gasket secondary to use.
In actual the use, the thickness that rubber washer can be set from inside to outside increases gradually.Like this, the link of straight coupling both sides, for example steering oil pipe and steering pump are more abundant with the extruding of straight coupling, good sealing effect.
The partial structurtes schematic representation of the hydraulic system that Fig. 4 provides for the utility model embodiment, this hydraulic system comprises steering oil pipe 5 and steerig pump 4, wherein also comprise the hydraulic system straight coupling that the utility model any embodiment is provided, the two ends of this straight coupling tighten with steerig pump 4 with steering oil pipe 5 respectively and are connected.
In this system, steering oil pipe and steering pump are connected owing to adopt rubber washer with straight coupling, and its plasticity is good, and is easy for installation, simplified the installation of whole system, and good seal performance, is convenient to safeguard.
The utility model embodiment also provides a kind of automobile, the hydraulic system that is provided comprising the utility model any embodiment.
This technological scheme is particularly useful for H4 type sample car applicable to any vehicle.
It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned each embodiment put down in writing, and perhaps part technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment's technological scheme of the utility model.
