Abstract
The invention discloses an axial riveting and clamping structure and a clamping process thereof. A steering spindle penetrates through a steering column tube through an upper bearing and a lower bearing; the outer ring of the lower bearing is in interference fit with the steering column tube; a stepped groove is processed on the inner surface of the steering column tube and is used for positioning the lower bearing. The axial length size of the shaft is changed along with temperature, so that the upper bearing is not positioned axially and has a free design. Because the clamping effect caused by the interference fit is not reliable enough, multiple grooves are formed on the circumference at the tail end of the steering column tube, and the grooves are extruded by using a riveting machine, so that the lower bearing is riveted and is firmly clamped, and the service performance can be guaranteed in a vibrating environment and the like. The parts are prevented from being tightened by adding the parts, the cost can be saved, and the structure is simple.
Description
Technical field
The present invention relates to steering axles and axially step up technical field, be specifically related to a kind of steering axles and axially rivet clamping structure and clamp technology.
Background technology
The conventional steering axle axially steps up, and often adopts locknut, pins locknut with stove bolt simultaneously, prevents to take place to become flexible in Steering gear work, causes the accident.Though it is reliable that this kind axially steps up mode, complex structure increases productive costs.Narrow and small owing to the space when locknut is installed simultaneously, comparatively difficulty is installed, manpower and materials expend more.Also there is the possibility that gets loose in the stove bolt that is used to pin locknut, and this has also increased the stability in use energy of whole assembly.The use of locknut, stove bolt increases assembly weight, and the running car cost increases.
Summary of the invention
Technical matters to be solved by this invention provides a kind of later-model steering shaft axially to step up mode in order to overcome defective and the deficiency that exists in the prior art.
Technical scheme: a kind of axial riveted joint clamps technology, steering shaft is loaded in the steering-column tube by upper and lower bearing carrier ring, on the lower bearing groove end face of steering-column tube lower end uniform be provided with at least three the riveted joint grooves, utilize rivet machine that each riveted joint groove is carried out reaming and make and respectively rivet the groove inwall and produce to center of circle direction and move radially, thus with the lower bearing clamp fitting in the lower bearing groove.
Interference fit between the outer ring of described lower bearing and the lower bearing groove.
Satisfying head bearing can play in the head bearing groove.
A kind of axial riveted joint clamping structure, comprise steering-column tube, steering shaft and upper and lower bearing, the lower bearing groove that the top and bottom of described steering-column tube are provided for installing the head bearing groove of bearing respectively and are used to install lower bearing, steering shaft is loaded in the steering-column tube by upper and lower bearing carrier ring, wherein, on the end face of lower bearing groove uniform be provided with at least three the riveted joint grooves, the outer wall thickness of described riveted joint groove is greater than inner wall thickness; Interference fit between the outer ring of lower bearing and the lower bearing groove.
The axial width of head bearing groove is greater than the width of head bearing outer ring.
Described steering-column tube inwall is provided with step trough, is set with locating bush in the steering shaft outside simultaneously, and locating bush cooperates the steering shaft axial location with step trough.
Beneficial effect of the present invention:
1. the structure, material of utilizing steering-column tube self are avoided increasing part and are stepped up part by the riveted joint machine riveting, can save cost, make simple in structure.In the course of processing, simple to operate.Utilize ductility and insensitive contractibility of die casting aluminium, in lower bearing play range of sizes, make material generation micro-displacement, step up lower bearing, realize that steering shaft axially steps up.
2. column tube material is a die casting aluminium, and ductility is good, and shrinkage is not obvious, so it is better to step up effect.
3. the riveting process implementation procedure is simple, and the riveted joint effect is better, and in-use performance is stable, and is simple in structure, assembly weight saving.
4. riveting technology has been widened the thinking and the application of mechanical innovation area in the application that axially steps up positioning field.Simplify physical construction greatly, economize on resources.
Description of drawings
Fig. 1 is a cross-sectional view of the present invention;
Fig. 2 is the perspective view of internal cylinder among Fig. 1.
Number in the figure 1 is a steering shaft, and 2 is head bearing, and 3 is steering-column tube, and 4 is lower bearing, and 5 is joint yoke, and 6 is step trough, and 7 is locating bush, and 8 are the riveted joint groove.
The specific embodiment
Embodiment 1: a kind of axial riveted joint clamps technology, the steering-column tube top and bottom of automobile are provided with head bearing groove and lower bearing groove respectively, steering shaft is loaded in the steering-column tube by upper and lower bearing carrier ring, on the lower bearing groove end face of steering-column tube lower end uniform be provided with many riveted joint grooves, utilize rivet machine that each riveted joint groove is carried out reaming and make and respectively rivet the groove inwall and produce to center of circle direction and move radially, thus with the lower bearing clamp fitting in the lower bearing groove.Simultaneously, interference fit between the outer ring of lower bearing and the lower bearing groove.The axial length dimension of considering steering shaft 1 can be along with temperature traverse, makes the head bearing can play in the head bearing groove, and head bearing does not axially have the location, the design of moving about.For lower bearing, the position is determined, but because in the steering column assembly working process, self constantly shakes, the reliability of considering the clamping effect that interference fit produces is not enough, so use rivet machine that the described groove of respectively riveting is pushed, lower bearing is riveted like this, clamp firmly, in environment such as vibrations, can guarantee in-use performance.
Embodiment 2: referring to Fig. 1 and Fig. 2, a kind of axial riveted joint clamping structure, the top and bottom of steering-column tube 3 are provided for head bearing groove and lower bearing groove respectively, head bearing 2 is installed in the head bearing groove, lower bearing 4 is installed in the lower bearing groove, steering shaft 1 is loaded in the steering-column tube 3 by upper and lower bearing carrier ring, and the lower end of steering shaft 1 also is connected with joint yoke 5.
The axial width of head bearing 2 grooves is greater than the width of head bearing outer ring, so head bearing does not axially have the location, the design of moving about can be along with temperature traverse to length dimension when steering shaft 1, and play can take place in the outer ring of head bearing 2.
Interference fit between the outer ring of lower bearing and the lower bearing groove.And on the end face of lower bearing groove uniform three or six the riveted joint grooves 8 that are provided with, each rivets the outer wall thickness of groove 8 greater than inner wall thickness, when utilizing rivet machine that each riveted joint groove 8 is pushed, radial variations can inwardly take place in each inwall of riveting groove 8.The material of steering-column tube 3 is a die casting aluminium, and ductility is good, and shrinkage is not obvious, so it is better to step up effect.Riveting technology has been widened the thinking and the application of mechanical innovation area in the application that axially steps up positioning field.
Described steering-column tube 3 inwalls are provided with step trough 6, are set with locating bush 7 in the steering shaft outside simultaneously, and locating bush 7 cooperates steering shaft 1 axial location with step trough 6.
