Description
Technical field
The utility model relates to a kind of vehicular spare parts, and what be specifically related to is a kind of ball head of suspension arm of automobile assembly.
Background technology
The effect of ball head of suspension arm of automobile in suspension arm is the transmission of power.In sizable degree, depend on the life-span of bulb the service life of suspension arm, work under bad environment residing for car chassis suspension, therefore, the connection of bulb and swing arm frame is particularly crucial, and bulb departs from swing arm frame can cause train operation accident.
Suspension arm bulb and be connected with the mode that a kind of employing press-fits, namely the cooperation attachment face of bulb assembly becomes interference fit with swing arm frame mounting hole site, as shown in Figure 1, press-fits rear pull-out force requirement and is greater than 23KN, and the easy pull-off of too small swing arm was lost efficacy, and caused train operation accident.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of ball head of suspension arm of automobile assembly improving suspension arm bulb pull-out force.
For achieving the above object, the utility model provides following technical scheme: a kind of ball head of suspension arm of automobile assembly, comprise bulb assembly and swing arm, described swing arm is provided with the mounting hole site of installing bulb assembly, mounting hole site on described bulb assembly described in correspondence is provided with and coordinates attachment face and spacing block set, described cooperation attachment face and described mounting hole site interference fit, described spacing block set is connected on the end face of described mounting hole site, and on described cooperation attachment face, the position of corresponding described spacing block set is provided with reducing groove.
By adopting technique scheme, cooperation attachment face on bulb assembly and the mounting hole site interference fit in swing arm, spacing block set on bulb assembly serves spacing cooperation, improves the effect coordinating accuracy rate, owing to being interference fit, in swing arm, the aperture of mounting hole site is less than external diameter bulb assembly coordinating attachment face, in the reducing groove that the inwall of mounting hole site in swing arm is embedded on cooperation attachment face, effectively improve the pull-out force of suspension arm bulb, improve the safety of running car.
The utility model is set to further: the cross-sectional plane of described reducing groove is square, and the length of described reducing groove is no more than the half of described cooperation attachment face length.
By adopting technique scheme, ensure that the area coordinating interference fit on attachment face, what bulb assembly was coordinated in the mounting hole site of swing arm is more reasonable, increases the service life.
The utility model is set to further: described reducing groove is symmetrically arranged amongst on the side face of described cooperation attachment face in pairs.
By adopting technique scheme, the setting of the paired symmetric offset spread of reducing groove, when making the mounting hole site reply pull-out force in swing arm, stressed more evenly reasonable.
The utility model is set to further: described reducing groove circumference on described cooperation attachment face is arranged.
By adopting technique scheme, when making the mounting hole site reply pull-out force in swing arm, stressed more evenly reasonable.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the prior art schematic cross-section of the utility model detailed description of the invention;
Fig. 2 is the schematic cross-section of the utility model detailed description of the invention.
Detailed description of the invention
As shown in Figure 2, the utility model discloses a kind of ball head of suspension arm of automobile assembly 1, comprise bulb assembly 1 and swing arm 2, swing arm 2 is provided with the mounting hole site 21 of installing bulb assembly 1, on bulb assembly 1, corresponding mounting hole site 21 is provided with and coordinates attachment face 11 and spacing block set 12, coordinate attachment face 11 and mounting hole site 21 interference fit, spacing block set 12 is connected on the end face of mounting hole site 21, is provided with reducing groove 13 coordinating the position of corresponding spacing block set 12 on attachment face 11.By adopting above-described embodiment, cooperation attachment face 11 on bulb assembly 1 and mounting hole site 21 interference fit in swing arm 2, spacing block set 12 on bulb assembly 1 serves spacing cooperation, improves the effect coordinating accuracy rate, owing to being interference fit, in swing arm 2, the aperture of mounting hole site 21 is less than external diameter bulb assembly 1 coordinating attachment face 11, in the reducing groove 13 that the inwall of mounting hole site 21 in swing arm 2 is embedded on cooperation attachment face 11, effectively improve the pull-out force of suspension arm bulb, improve the safety of running car.
The cross-sectional plane of reducing groove 13 is square, and the length of reducing groove 13 is no more than the half coordinating attachment face 11 length.By adopting above-described embodiment, ensure that the area coordinating interference fit on attachment face 11, what bulb assembly 1 was coordinated in the mounting hole site 21 of swing arm 2 is more reasonable, increases the service life.
Reducing groove 13 is symmetrically arranged amongst on the side face of cooperation attachment face 11 in pairs.By adopting above-described embodiment, the setting of the paired symmetric offset spread of reducing groove 13, when making the mounting hole site 21 in swing arm 2 tackle pull-out force, stressed more evenly reasonable.
Reducing groove 13 circumference on cooperation attachment face 11 is arranged.By adopting above-described embodiment, when making the mounting hole site 21 in swing arm 2 tackle pull-out force, stressed more evenly reasonable.
