Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the structural drawing of lining 3.
Embodiment
Describe technological scheme of the present invention in detail by the following examples, should be understood that, following embodiment only can be used for explaining and technical solution of the present invention being described and can not being interpreted as being the restriction to technical solution of the present invention.
Fig. 1 is the front view of guiding spring assembly of the present invention, and this guiding spring assembly comprises guiding piece 1, carrying tablet 2 and lining 3 and anti-attrition sheet 4,5,6 and the formations such as spring assembly bolt 12 that lead.
An end of guiding piece 1 is provided with guiding piece grasswort 10, an end of carrying tablet 2 is provided with carrying tablet grasswort 11, guiding piece grasswort 10 is arranged in carrying tablet grasswort 11, it is inner that lining 3 is installed on guiding piece grasswort 10, guiding spring is divided into forward part A, rear section B by guiding spring assembly bolt 12, as Fig. 1, the ratio A/B of anterior length A and rear portion length B can determine to lead the carrying ratio of spring assembly and pneumatic spring; Guiding piece grasswort 10 has a central point with carrying tablet grasswort 11, an end 13 upper surface line relative with carrying tablet grasswort 11 in carrying tablet 2 and guiding spring assembly bolt 12 intersection point, connect the line of central point and intersection point, this line with forming angle a with an end 13 upper surface line relative with carrying tablet grasswort 11 in carrying tablet 2, this angle a be arranged in by with a carrying tablet 2 end 13 upper surface line relative with carrying tablet grasswort 11 on horizontal axis and the 2nd quadrant of system of coordinates formed for vertical shaft with the spring bolt 12 that leads or the 3rd quadrant or horizontal axis; Guiding piece 1 is oppositely provided with arc-shaped bend with guiding piece grasswort 10 curl direction, and carrying tablet 2 is oppositely provided with arc-shaped bend with carrying tablet grasswort 11 curl direction; Wherein guiding piece 1 is less than radius of curvature 8 away from guiding piece grasswort 10 end near the radius of curvature 7 of guiding piece grasswort 10 end.The radius of curvature 9 of carrying tablet 2 is less than the radius of curvature 8 of guiding piece 1 away from guiding piece ear-rolling end.
Namely the lead part of spring bolt about 12 of the intermediate portion of carrying tablet 2 and guiding piece 1 one end relative with guiding piece grasswort 10 is flat construction; Carrying tablet 2 is greater than the radius of curvature 7 of guiding piece 1 near guiding piece grasswort 10 end near the radius of curvature 9 of carrying tablet grasswort 11 end, both radius of curvature are being tending towards equal close to guiding spring assembly intermediate portion place, and intermediate portion generally refers near guiding spring assembly bolt 12.Such structure after guiding piece 1 and carrying tablet 2 are installed in carrying tablet and guiding piece grasswort and lead between spring bolt and be formed with a space.
The grasswort height of this guiding spring assembly front end guiding piece 1 is lower than attachment face on guiding spring assembly, and namely adopt negative arc high form, the guiding steady that this arrangement enhances this guiding spring is qualitative, and reduces the back axle four-wheel aligner deviation because guiding spring camber error causes.
Guiding piece 1 and carrying tablet 2 front end all adopt iso-stress variable section structure, effectively can lower the weight of guiding spring.Guiding piece 1 front end grasswort adopts flat grasswort structure, and this structure can reduce the stress of guiding piece grasswort root effectively.
In the middle of guiding piece 1 and carrying tablet 2 and two sides is separately installed with anti-attrition sheet 4,5,6, reduces guiding piece 1 and the area of contact of carrying tablet 2, to reduce both frictions, can reduce noise and the dynamic stiffness of guiding spring assembly.
Lining 3 is installed on the grasswort place of guiding piece 1, and lining and grasswort adopt interference fit.As Fig. 2, require that lining inner ring length is greater than guiding piece front end grasswort width.
Carrying tablet 2 rear end adopts forging and stamping to reduce thickness gradually, end is straight for the assembling of pneumatic spring, both sides adopt trimming structure, reduce carrying tablet 2 rear end width, carrying tablet is upper surface with the parallel rectangular configuration of lower surface away from carrying tablet ear-rolling end, and the thickness of rectangular configuration is less than the thickness of carrying tablet other parts; The width of rectangular configuration is less than the width of carrying tablet other parts.
Fig. 3 is the structural representation of lining 3, is formed by natural rubber, inner ring, outer ring sulfuration.Wherein outside inner ring 31, groove 33 is all had inside outer ring 32, to strengthen sulfurating strength.Outer ring length is identical with guiding piece 1 grasswort width, and inner ring 31 length is greater than outer ring 32 length.
Although illustrate and describe embodiments of the invention, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments without departing from the principles and spirit of the present invention, scope of the present invention is by claims and equivalency thereof.
