Abstract
The invention relates to a thrust bar joint, in particular to a thrust bar joint for heavy-duty vehicles. The thrust bar joint comprises a joint body (4) and a connection shaft (1) arranged in the joint body (4). The thrust bar joint is characterized in that a flexible body (7) is arranged in the space between the connection shaft (1) and the joint body (4). The characteristics of the flexible body can enable the connection shaft to be adjusted by corresponding angles no matter two bridges sway in horizontal direction or in vertical direction, thus alleviating the counter force of the vehicleto the thrust bar, preventing the connection from being damaged and protecting the connection shaft. The thrust bar joint has high bearing strength, abrasion resistance, and low manufacture and use cost.
Description
Technical field:
What the present invention relates to is a kind of propulsion rod joint, relates in particular to a kind of heavy load vehicle propulsion rod joint.
Background technology:
Propelling rod at commercial trucks such as the east wind of prior art, liberation has two fittings bodies, connects attaching parts between two fittings bodies, and fittings body adopts cast-type polyurethane cover, cooperates the column adapter shaft in the polyurethane cover.The propelling rod of this polyurethane cover can not move freely in automobile sport, is to lean on the elasticity of polyurethane to come adjusting motion and be subjected to force direction, the discontinuity between two bridges, lean on polyurethane stressed, loading strength is low, and is easy to wear, joint damages easily, and the propelling rod life-span is short.And manufacturing cost height.This is the existing in prior technology weak point.
Summary of the invention:
Purpose of the present invention is exactly that a kind of loading strength is big, wear-resistant, the propulsion rod joint of low cost of manufacture and provide at the existing in prior technology deficiency.
This programme is realized by following technical measures: a kind of propulsion rod joint, comprise fittings body and be installed in the interior adapter shaft of fittings body, in the space between adapter shaft and the fittings body flexible body is installed, skeleton is arranged in the flexible body, described skeleton is the back plate (5) that is arranged on the adapter shaft, and flexible body (7) is made up of the two parts that are positioned at back plate (5) both sides.
This programme is a characteristic of utilizing flexible body, and no matter two bridges swing or swing up and down, and all can make the corresponding angle of adapter shaft adjustment, have alleviated the antagonistic force of automobile to propelling rod, make adapter shaft not fragile, and adapter shaft is had protective effect.This adapter shaft can be bearing pin.Flexible body can be made for rubber or other elastomeric materials with certain intensity.Flexible body is a flush fit with cooperating of fittings body, prevents to rotate mutually between them.
Skeleton is arranged in the flexible body, and the skeleton in the flexible body can strengthen the bulk strength of flexible body, increases the service life of flexible body.This skeleton is the back plate that is arranged on the adapter shaft, can also built-in hard material of while in flexible body.If the requirement of strength to flexible body is not high, this skeleton is the back plate that is arranged on the adapter shaft; If the requirement of strength to flexible body is higher, then both needed to be arranged on the connecting panel on the adapter shaft, also hard material need be set in flexible body.But for the consideration to manufacturing cost, this skeleton is that the back plate that is arranged on the adapter shaft is good.Back plate can be for captiveing joint, as welding with adapter shaft.Back plate can be arranged on left part or the right part or the middle part of adapter shaft, and flexible body is made of the two parts that are positioned at the connecting panel both sides like this.For the ease of manufacturing, cost-cutting, be convenient to maintenance, left and right sides flexible body adopts same structure, its connecting panel operated by rotary motion is at the middle part.
In order to prevent the flexible body wearing and tearing, prolong its service life, reduce use cost simultaneously, wear-resisting mechanism is arranged between flexible body and the back plate.Wear-resisting mechanism can also can be independently wear-resisting lubricating pad for being arranged on the wearing layer on flexible body surface.Use independently wear-resisting lubricating pad to reduce production costs, can also reduce use cost, and be convenient to maintenance.For the consideration of cost performance, wear-resisting lubricating pad can be made by nylon material.The surface of wear-resisting lubricating pad is provided with damper bar and oil groove, on two surfaces of their difference wear-resisting lubricating pads in position.Match with flexible body in the wear-resisting lubricated surface that is lined with damper bar, after assembling was finished, damper bar was pressed into flexible body, and it is fixed together, and prevents relatively rotating between them.Matching with back plate in the wear-resisting lubricated surface that is lined with oil groove, adds lubricating oil during use, can reduce the friction between them.Damper bar and oil groove can be set to a plurality of, and for the consideration to wear-resisting lubricating pad intensity, damper bar and oil groove can be the corresponding setting of dislocation.
The outside face middle part evagination of flexible body, end cap is equipped with in its outside, and end cap is the annulus that the cross section is bending, can increase its sealing property, prevents to enter in the fittings body dirt.Green phase cooperates between the location for convenience, end cap and flexible body groove and bulge loop are located.End cap is defined in the fittings body by snap ring.
The beneficial effect of this programme can be learnt according to the narration to such scheme; because the characteristic of flexible body in this scheme; no matter two bridges swing or swing up and down; all can make the corresponding angle of adapter shaft adjustment; alleviated the antagonistic force of automobile to propelling rod; make adapter shaft not fragile, adapter shaft is had protective effect.And its loading strength height, wear-resistant, manufacturing cost and use cost is low, be arranged on back plate on the adapter shaft make its loading strength height, wear-resistant, manufacturing cost and use cost is low.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
