Description
Technical field
The utility model relates to a kind of wheel stand lining in automobile chassis suspension field.
Background technology
Wheel stand is the vitals of automobile, bears the force and moment that wheel and vehicle body pass over, and makes that car load is stable to travel.Wheel stand has been connected with vehicle beam by wheel stand lining, and play connection and shock absorbing effect, the design of wheel stand lining is directly connected to traveling comfort and the stationarity of car load.
Wheel stand is widely used in Car Industry, wheel stand is connected with crossbeam with M12*10.9 grade bolt by wheel stand lining, the effect of wheel stand lining is the energy-absorbing function by rubber element, relative motion between isolation vehicle body and wheel stand, to obtain good vibration noise index and endurance quality.
Refer to Fig. 1, the automotive wheel support lining 1 of prior art comprises inner frame 1', polysulphide rubbers obturator 2' and the purchasing ore 3' of from inside to outside coaxial setting successively, inner frame 1' is cylindrical shape, it is circular through hole 4' that the center of the inner frame 1' axis offered along this inner frame 1' offers a cross sectional shape, and namely inner frame 1' is the columnar structured of inner hollow.Purchasing ore 3' is also the columnar structured of inner hollow.The height of inner frame 1' is greater than the height of purchasing ore 3'.
The inner frame 1' of automotive wheel support and automotive wheel support lining and purchasing ore 3' is metal material.Automotive wheel support is connected with automotive wheel support lining in an interference fit.
In order to realize lightweight, the inner frame of wheel stand and wheel stand lining and purchasing ore are all aluminum alloy materials, and density is low, quality is light.The assembling of wheel stand and wheel stand lining is interference fit, because the hardness of aluminum product is low, even if wheel stand lining sound rigidity meets the requirements, also there is assembly problem.The sectional area of inner frame 1' is less than normal, under actual entrucking state, M12*10.9 grade bolt can produce the axial pre tightening force of 88KN, this predetermincd tension can to the inner frame 1' of wheel stand lining and and the crossbeam of inner frame 1' two side contacts produce and extrude, relatively excessive predetermincd tension can cause inner frame 1' plastic deformation and crossbeam by conquassation, thus affect the connection reliability of whole back axle, can potential safety hazard be brought to the safe driving of automobile.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of wheel stand lining is provided, substantially increase the axial compression resistance sex change energy of inner frame, reduce the crushing strength of bolt pretightening to vehicle body, extend the service life of this place's wheel stand lining.
A kind of technical scheme realizing above-mentioned purpose is: a kind of wheel stand lining, comprise the inner frame of from inside to outside coaxial setting successively, polysulphide rubbers obturator and purchasing ore, described purchasing ore cylindrically structure, the height of described inner frame is greater than the height of described purchasing ore;
Described inner frame comprises the first bell mouth shape section, cylindrical shape section and the second bell mouth shape section that are connected successively from top to bottom, and described first bell mouth shape section, cylindrical shape section and the second bell mouth shape section are coaxially arranged and one-body molded;
The large end of described first bell mouth shape section is arranged upward, and the large end of described second bell mouth shape section is arranged down;
The height of described cylindrical shape section is greater than the height of described purchasing ore, and described first bell mouth shape section and the second bell mouth shape section are positioned at the upper and lower of described purchasing ore correspondingly;
It is circular through hole that the center of described inner frame offers a cross sectional shape along the axis of this inner frame.
Above-mentioned a kind of wheel stand lining, wherein: the neighboring of the upper and lower end face of described purchasing ore is all in rounding.
Have employed the technical scheme of a kind of wheel stand lining of the present utility model, comprise from inside to outside coaxial inner frame, polysulphide rubbers obturator and the purchasing ore arranged successively, purchasing ore is structure cylindrically, and the height of inner frame is greater than the height of described purchasing ore; Inner frame comprises the first bell mouth shape section, cylindrical shape section and the second bell mouth shape section that are connected successively from top to bottom, described first bell mouth shape section, cylindrical shape section and the second bell mouth shape section are coaxially arranged and one-body molded, and it is circular through hole that the center of inner frame offers a cross sectional shape along the axis of this inner frame.Its technique effect is: the axial compression resistance sex change energy substantially increasing inner frame on the one hand; reduce the crushing strength of bolt pretightening to vehicle body; extend the service life of this place's wheel stand lining; the face area contacted with crossbeam due to inner frame on the other hand increases; reduce the pressure that crossbeam unit area bears; thus protect crossbeam, improve the service life of crossbeam.
Accompanying drawing explanation
Fig. 1 is the structural representation of wheel stand lining of the prior art;
Fig. 2 is the structural representation view of a kind of wheel stand lining of the present utility model.
Detailed description of the invention
Refer to Fig. 2, contriver of the present utility model, in order to understand the technical solution of the utility model better, below by embodiment particularly, and is described in detail by reference to the accompanying drawings:
Refer to Fig. 2, a kind of wheel stand lining of the present utility model, comprise from inside to outside coaxial inner frame 1, polysulphide rubbers obturator 2 and the purchasing ore 3 arranged successively, purchasing ore 3 cylindrically structure, the neighboring of the upper and lower end face of purchasing ore 3 is all in rounding.
The height of inner frame 1 is greater than the height of purchasing ore 3; Inner frame 1 is divided into three sections in axially connecting, inner frame 1 comprises the first bell mouth shape section 11, cylindrical shape section 12 and the second bell mouth shape section 13, first bell mouth shape section 11, cylindrical shape section 12 and the second bell mouth shape section 13 that are connected successively from top to bottom and coaxially to arrange and one-body molded; The large end of the first bell mouth shape section 11 is arranged upward, and the large end of the second bell mouth shape section 13 is arranged down; The height of cylindrical shape section 12 is greater than the height of purchasing ore 3, and the first bell mouth shape section 11 and the second bell mouth shape section 13 are positioned at the upper and lower of purchasing ore 3 correspondingly; It is circular through hole 4 that the center of inner frame 1 offers a cross sectional shape along the axis of this inner frame 1.
