Abstract
The invention discloses a kind of axially riveted joint clamping structure and pinching process, turn to main shaft to pass steering-column tube by head bearing and lower bearing, lower bearing outer ring and steering-column tube are crossed to win and are coordinated, and steering-column tube inside face is processed with step trough and locates for lower bearing.The axial length dimension of consideration axle along with temperature traverse, so head bearing is axially without location, can be moved about and design.Consider that the reliability of the clamping effect that interference fit produces is inadequate, so output multiple groove on steering-column tube extreme circumferential, use rivet machine, groove is extruded, such lower bearing is riveted, and clamping firmly, can ensure in-use performance in the environment such as vibrations.Avoid increasing part to step up part, can be cost-saving, make structure 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 axially riveted joint clamping structure and pinching process.
Background technology
Conventional steering axle axially steps up, and often adopts locknut, pins locknut simultaneously with stove bolt, prevents from occurring to loosen in Steering gear work, causes the accident.Although this kind of axis steps up mode reliably, complex structure, makes productive costs increase.Simultaneously when installing locknut due to narrow space, install comparatively difficulty, manpower and materials expend more.Also there is the possibility got loose in the stove bolt for pinning locknut, which increases the stability in use energy of whole assembly.The use of locknut, stove bolt makes assembly weight increase, and running car cost increases.
Summary of the invention
Technical matters to be solved by this invention, in order to overcome the defect and deficiency that exist in prior art, provides a kind of novel steering shaft axially to step up mode.
Technical scheme: one axially rivets pinching process, steering shaft is loaded in 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 riveted joint grooves, utilizing rivet machine to carry out reaming to each riveted joint groove makes each riveted joint groove inwall move radially to the generation of direction, the center of circle, thus is fixedly clamped in lower bearing groove by lower bearing.
Interference fit between the outer ring of described lower bearing and lower bearing groove.
Meeting head bearing can play in head bearing groove.
One axially rivets clamping structure, comprise steering-column tube, steering shaft and upper and lower bearing, the top and bottom of described steering-column tube arrange the head bearing groove for installing bearing and the lower bearing groove for installing lower bearing respectively, steering shaft is loaded in 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 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 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, and outside steering shaft, be set with locating bush, locating bush coordinates steering shaft axial location with step trough simultaneously.
Beneficial effect of the present invention:
1. utilize the structure of steering-column tube self, material by riveted joint machine riveting, avoid increasing part to step up part, can be cost-saving, make structure simple.In the course of processing, simple to operate.Utilize the ductility of die casting aluminium and insensitive contractibility, in lower bearing play range of sizes, make material generation micro-displacement, step up lower bearing, realize steering shaft and axially step up.
2. column tube material is die casting aluminium, and ductility is good, and shrinkage is not obvious, therefore it is better to step up effect.
3. riveting process implementation procedure is simple, and riveted joint effect is better, and in-use performance is stablized, and structure is simple, assembly weight saving.
4. riveting technology is axially stepping up the application of positioning field, has widened thinking and the application in machinery innovation field.Greatly simplify physical construction, economize on resources.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present invention;
Fig. 2 is the perspective view of internal cylinder in Fig. 1.
Number in the figure 1 is 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 is riveted joint groove.
Detailed description of the invention
Embodiment 1: one axially rivets pinching process, the steering-column tube top and bottom of automobile arrange head bearing groove and lower bearing groove respectively, steering shaft is loaded in 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, utilizing rivet machine to carry out reaming to each riveted joint groove makes each riveted joint groove inwall move radially to the generation of direction, the center of circle, thus is fixedly clamped in lower bearing groove by lower bearing.Meanwhile, interference fit between the outer ring of lower bearing and lower bearing groove.Consider that the axial length dimension of steering shaft 1 can along with temperature traverse, make head bearing can play in head bearing groove, head bearing axially without location, travelling design.For lower bearing, position is determined, but due in steering column assembly working process, self constantly shakes, consider that the reliability of the clamping effect that interference fit produces is inadequate, so use rivet machine to be extruded by described each riveted joint groove, such lower bearing is riveted, clamping firmly, can ensure in-use performance in the environment such as vibrations.
Embodiment 2: see Fig. 1 and Fig. 2, one axially rivets clamping structure, the top and bottom of steering-column tube 3 arrange for head bearing groove and lower bearing groove respectively, head bearing 2 is arranged in head bearing groove, lower bearing 4 is arranged on lower bearing groove, steering shaft 1 is loaded in steering-column tube 3 by upper and lower bearing carrier ring, and the lower end of steering shaft 1 is also connected with joint yoke 5.
The axial width of head bearing 2 groove is greater than the width of head bearing outer ring, so head bearing is axially without location, travelling design, when steering shaft 1 can along with temperature traverse to length dimension, the outer ring of head bearing 2 play can occur.
Interference fit between the outer ring of lower bearing and lower bearing groove.And uniformly on the end face of lower bearing groove being provided with three or six riveted joint grooves 8, the outer wall thickness of each riveted joint groove 8 is greater than inner wall thickness, and when utilizing rivet machine to extrude each riveted joint groove 8, the inwall of each riveted joint groove 8 inwardly radial variations can occur.The material of steering-column tube 3 is die casting aluminium, and ductility is good, and shrinkage is not obvious, therefore it is better to step up effect.Riveting technology, axially stepping up the application of positioning field, has widened thinking and the application in machinery innovation field.
Described steering-column tube 3 inwall is provided with step trough 6, and outside steering shaft, be set with locating bush 7, locating bush 7 coordinates steering shaft 1 axial location with step trough 6 simultaneously.
