Abstract
The utility model relates to a turnover bearing of automobile cab, in particular to a modified automobile cab turnover bearing, which is characterized in that the outer surface of the end near a sleeve is provided with a shoulder, the surface of the sleeve is coated by a first rubber layer, the first rubber layer is provided with a rubber shoulder at the inner end of the sleeve shoulder, an open space is formed between the rubber shoulder and the inner end face of the sleeve shoulder and an open space is formed between the rubber shoulder and the first rubber layer, the circumference face of the rubber shoulder is sheathed by an inner metal ring, a second rubber layer is arranged outside the inner metal ring, and an outer metal ring is disposed outside the second rubber layer. The embodiment of the cab turnover bearing adds a composite rubber layer with good shock adsorption and buffer property on original metal sleeve structure, thereby reducing up-and-down vibration and left-and-right swing of cab, improving service life of the turnover bearing, releasing fatigue of driver and reducing noise. The turnover bearing has simple and reasonable structure, as one beneficial modification.
Description
Technical field
The utility model relates to the upset bearing of automobile cab, especially about a kind of improved automobile cab upset bearing.
Background technology
When automobile in motion, the up-down vibration that operator's compartment is subjected to and the power that swings are born by its set upset bearing.Yet the present structure of driver's cab turnover bearing generally is to be connected with hard contact between the metallic framework by metal sleeve pipe, or rubber layer that one deck approaches is only arranged as buffering.The structure of existing upset bearing does not have and alleviates or the effect and the effect of buffering vibration, and being rigidly connected between the metallic framework makes operator's compartment be subjected to vibrate or the destruction of oscillatory forces easily.
The utility model content
The purpose of this utility model is to have poor, the damageable defective of the existing cushion characteristic of driver's cab turnover bearing arrangement now for overcoming, and proposes a kind of improved automobile cab upset bearing.
The purpose of this utility model is achieved in that a kind of improved automobile cab upset bearing, comprise sleeve pipe, it is characterized in that being provided with shoulder at outside face near sleeve pipe one end, surface along the sleeve pipe profile is provided with first rubber layer, first rubber layer is provided with the rubber shoulder in a side that is positioned at sleeve pipe shoulder the inner, be provided with open circuited gap between rubber shoulder and sleeve pipe shoulder inner end surface and set first rubber layer, the periphery of rubber shoulder is arranged with interior wire loop, also be provided with second rubber layer outside the interior wire loop, be provided with outer wire loop outside second rubber layer; Open circuited gap is set to 0.2~4mm between rubber shoulder and sleeve pipe shoulder inner end surface and set first rubber layer; The ring surface of interior wire loop is provided with some circles or oval-shaped hole uniformly; The section of outer wire loop is arranged to the annulus of the square that is made of axial limit and longitudinal edge; Open circuited gap is set to 1mm between rubber shoulder and sleeve pipe shoulder inner end surface and set first rubber layer; The outer wire loop radially outer face of square edge is provided with rubber buffer ring, and the section form of rubber buffer ring is a triangle.
The utility model has the advantages that, press the driver's cab turnover bearing that this programme is implemented, owing on the basis of virgin metal sleeve structure, be provided with and have the good shock absorption and the composite rubber layer of cushion characteristic, flexibly connect with it and to have replaced original being rigidly connected, not only extenuated the operator's compartment up-down vibration and swung, and to the service life of raising upset bearing, and the alleviation driver fatigue all has positive role and effect with the reduction noise.The utility model is simple and reasonable, is a kind of useful improvement.
Description of drawings
Fig. 1 is the sectional structure scheme drawing of a kind of embodiment of the utility model;
Fig. 2 is the sectional structure scheme drawing of the utility model in assembling.
The specific embodiment
Be described in further detail with regard to this embodiment in conjunction with the accompanying drawings.Be provided with shoulder 11 at left end (by graphic direction) near the thick sleeve pipe 1 of aluminium ingot system, surface in sleeve pipe 1 profile that is shaped on shoulder 11 is bonded with first rubber layer 2, a side that is positioned at sleeve pipe shoulder 11 the inners at first rubber layer 2 is provided with rubber shoulder 21, the radial wall thickness of rubber shoulder 21 is greater than the thickness at these other positions of rubber layer, open circuited gap 2111 is set to 1mm (scope of this gap can be 0.2~4mm), to guarantee that rubber has enough deformation spaces when being subjected to radial compression between rubber shoulder 21 and sleeve pipe shoulder 11 inner end surfaces and set first rubber layer.For strengthening the inherent rigidity and the intensity of yielding rubber layer, put interior wire loop 3 in that the periphery of rubber shoulder 21 is sticking, also be bonded with second rubber layer 4 outside the interior wire loop 3, be provided with the hole (accompanying drawing slightly shows) of some circles (or oval) uniformly at the ring surface of interior wire loop 3, when bonding first and second rubber layers, rubber can cause the rubber shoulder 21 and second rubber layer 4 to link and be one, to strengthen damping performance and buffering effect by the circular hole of wire loop 3 in being located at.For finishing the equipped of operator's compartment; and protection rubber layer; wire loop 5 outside outside second rubber layer 4, being provided with; the section of outer wire loop 5 is arranged to the annulus of the square that is made of axial limit 51 and longitudinal edge 52, and it is leg-of-mutton rubber buffer ring 53 that the end face of the longitudinal edge of outer wire loop 5 is provided with its section.
The utility model is when being assemblied in operator's compartment, be with operator's compartment up and down suspension strut be installed among the upset bearing, be about to the left side (by graphic direction) that a wire loop 55 identical with outer wire loop 5 shapes that are bonded in second rubber layer 4 is fitted to the upset bearing, the integral structure that assembles is from radially, wire loop 55 and the upset outer wire loop 5 relative centres in the bearing form a groove, and the portion of suspension strut up and down 6 of operator's compartment embeds in these grooves.
