Abstract
The utility model discloses an elastic hybrid lining assembly of a steel plate spring, which comprises a shaft pipe and a pair of jacket assemblies, wherein the jacket assemblies are sleeved at the two ends of the shaft pipe, each jacket assembly comprises an outer jacket and an inner jacket assembly, the outer jacket is assembled between the shaft pipe and the inner jacket assembly, one end of the outer jacket and one end of the inner jacket assembly are provided with round end faces protruding radially, the inner side of the round end face of the outer jacket and the outer side of the round end face of the inner jacket assembly are appressed to form a jacket assembly round end face, the outer side of the jacket assembly is flush with the end face of the shaft pipe, the outer end face of the outer jacket is provided with conical bumps, and half round posts are uniformly distributed at the radial periphery of the inner jacket assembly. By relative rotation of the shaft pipe and the outer jacket, friction and abrasion between a plate spring rolled lug and a plate spring pin can be prevented, the service lives of the plate spring and the plate spring pin are prolonged; due to the application of an elastic material, vibration and noise can be reduced, the elastic hybrid lining assembly is free from maintenance, and the smoothness and the steering stability of the whole vehicle are improved.
Description
Technical field
The utility model relates to a kind of leaf spring bushing assembly, relates to a kind of steel spring elasticity mixed type bush Assembly in particular.
Background technology
Continuous development along with the truck technology; The client requires constantly to improve to car load ride comfort, road-holding property, gently blocks the load that suspension has no longer just been paid attention to vehicle, and the suspension system part is also in continuous development; The oldfashioned leaf spring bushing is base steel copper back of the body bimetallic material; Need to add butter as grease, other functions can not be provided, and poor reliability.The novel lining that existing market adopts; Material mainly adopts polyurethane, rubber, reaches rubber and steel pipe mixed system etc.; Light card below 3 tons adopts the polyurethane lining more; 3 ~ 6 tons light card main flows adopt rubber, iron mixed system lining, more do not have shock-absorbing, a decrease of noise functions but the novel lining reliability of this type is barely satisfactory.
The utility model content
The utility model technical matters to be solved is, overcomes the shortcoming of prior art, and a kind of steel spring elasticity mixed type bush Assembly is provided, and reduces vibrations and noise, improves steel spring and leaf spring pin life-span.
The steel spring elasticity mixed type bush Assembly of the utility model; Comprise central siphon and a pair of sheath assembly that is placed in the central siphon two ends; The sheath assembly comprises oversheath and inner sheath assembly, and oversheath is assemblied between central siphon and the inner sheath assembly, and oversheath and inner sheath assembly one end all have circular end surface; The circular inner end surface of oversheath is fitted with inner sheath assembly circular outer ends face, outside sheath assembly circular end surface is positioned at and with the central siphon end face.
Aforesaid steel spring elasticity mixed type bush Assembly, inner sheath assembly outer radial periphery rectangular distribution semicolumn projection reaches and the inboard friction force of leaf spring grasswort to guarantee the pulling-out force after the bush Assembly assembling; The oversheath outer face has tapered protrusion, and tapered protrusion contacts with the hanger inner side end, with assorted dirty infiltration the such as dust protection, muddy water.
Further, aforesaid steel spring elasticity mixed type bush Assembly, said inner sheath assembly is combined by M170 rubber layer and PA66 nylon layer, and said PA66 nylon layer is adhered to said M170 rubber layer inboard through sulfuration.
The beneficial effect of the utility model is: (1) relatively rotates through central siphon and oversheath, can avoid mutual friction mutually, wearing and tearing between leaf spring grasswort and the leaf spring pin, prolongs the service life of leaf spring and leaf spring pin; (2) can reduce vibrations and noise, non-maintaining, need not lubricated and maintenance, non-maintaining in the ride comfort of raising car load, the daily use of road-holding property (3) vehicle, the time and the cost that have reduced maintenance and safeguarded.
Description of drawings
Fig. 1 is the present embodiment structural representation
The specific embodiment
A kind of steel spring elasticity mixed type bush Assembly that present embodiment provides; Structure is as shown in Figure 1; Comprise central siphon 1 and a pair of sheath assembly that is placed in the central siphon two ends; The sheath assembly comprises oversheath 2 and inner sheath assembly 3, and oversheath 2 is assemblied between central siphon 1 and the inner sheath assembly 3, and an end of oversheath 2 and inner sheath assembly 3 all has radially outstanding circular end surface; The inboard applying with the inner sheath assembly 3 circular end surface outside of oversheath 2 circular end surface constitutes sheath assembly circular end surface, the outside of sheath assembly circular end surface and with central siphon 1 end face.
When assembling, oversheath 2 at first assembles with inner sheath assembly 3, the sheath assembly that assembles is assemblied on the central siphon 1 again, after the entrucking, has the 1mm tapered protrusion to contact with the hanger inner end surface on the oversheath 1 big disc end face, with assorted dirty infiltration the such as dust protection, muddy water.
The central siphon of the utility model is 45 steel pipes that intensity is high, load-carrying capacity is strong, and the shaft tube inner wall roughness of surface reaches 0.8, so that reduce friction and drop to central siphon, tie bolt wearing and tearing minimum; Oversheath adopts modification of nylon PA66 material, and performances such as the physical mechanical of modification of nylon are all superior than nylon, and mechanical strength is high, and is wear-resisting, self-lubricating property good; Friction durability is higher 4 ~ 5 times than steel, iron, pulley, and the adaptive temperature wide ranges can be used in-40 ℃ ~ 100 ℃ scopes, can damping; Do not produce noise, running is steady, and light weight, density are 1/7 of steel, 1/8 of copper; 1/2.5 of aluminium, withstanding corrosion, non-corrosive; Inner sheath adopts mechanical strength height, the heat-resistant antifriction damage M170 rubber layer that performance is good, friction coefficient is low and the bond material of PA66 nylon layer.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
