Description
Technical field
The present invention relates to vehicle transmission technical applications, more particularly to a kind of integrated rzeppa joint and wheel cincture
Axis nesting system, can make wheel side and half shaft transmission system highly compact, improve transmission efficiency, save chassis spring down space and account for
With.
Background technology
The kind of drive that semiaxis adds universal joint is widely used in vehicle transmission.It is most-often used in existing universal joint
Three kinds of universal joints are fixing type equal speed universal joint respectively（BJ type universal joints）, six bead telescoping universal joints（DOJ type universal joints）With
Three pin-type telescoping universal joint（TJ type universal joints）.Wherein, the semiaxis swing angle scope of fixing type equal speed universal joint is 0 ° ~ 36 °,
Do not possess retractility, mode of transfer force is six bead, it is necessary to be processed with five-axis machine tool；Six bead telescoping universal joint semiaxis are swung
Scope is 0 ° ~ 30 °, has retractility, mode of transfer force is also six bead, and three-head milling machine can be processed, and difficulty of processing is low；Three pin-type
Telescoping universal joint semiaxis hunting range is 0 ° ~ 23 °, possesses retractility, by three pin ball power transmissions, it is necessary to which five axis milling machines could be processed
Go out complex appearance.
Existing " a kind of new rzeppa joints of 104154136 A of CN ", " 105452694 A of CN are used for vehicle
Slip Rzeppa constant velocity joint ", " the direct pinion gear installing type universal joints of 106015373 A of CN ", " 106555824 A of CN
The patents such as a kind of cage universal joint, card gear and automobile ", refer to the improvement project to rzeppa joint,
But improvement of these patents to more ripe traditional rzeppa joint, be limited only to improvement to cage internal structure and
The improvement of cage and semiaxis type of attachment, does not all account for rzeppa joint and takes turns the wound of the connection scheme of the axle system on side
Newly, the integration and optimization of wheel side and half axle system is not considered, is not also considered how to save space, is reduced unsprung mass, subtracts
Movement interference etc. under few spring.
Spline is widely used in the connection mode of axle system of the existing rzeppa joint with taking turns side to be connected, and have lost
While a part of transmission efficiency, also have the shortcomings that volume is big, weight is big.It is effective as one how spline fitted is saved
It is driven improvement direction.Therefore, the axle articulation of rzeppa joint and wheel side is integrated, has and save space, reduce interference, letter
The advantages that changing the design of wheel side, increase transmission efficiency, has a extensive future, lightweight to vehicle and the universality energy such as handling
Lifting be of great significance.
The content of the invention
It is an object of the invention to cause overall structure space to account for for spline fitted existing for current rzeppa joint
With the problem such as big and transmission efficiency is low, there is provided a kind of integrated rzeppa joint system nested with cincture axis is taken turns.Whole system
Unite compact-sized, accurate, it is highly integrated to take turns side and rzeppa joint, the connection of semiaxis, can mitigate automobile unsprung mass, realize
Coordinate compact, lightweight, reduce rotary inertia, increase transmission efficiency and other effects.The present invention include over all Integration conceptual design and
Each parts design in system, further includes the cooperation between parts and limit method.
Technical solution is used by the present invention realizes above-mentioned purpose and solves its technical problem.
The present invention is monolithically fabricated axle system part and rzeppa joint system and semiaxis including taking turns side；Wrapped after fractionation
Include rim bolt, wheel shaft, screw thread spacing ring, split pin, rzeppa joint shell, limit stop ring, retainer, ball, planet
The parts such as frame, axis clamp spring, semiaxis.
The rzeppa joint, rzeppa joint shell are designed using hollow type tubular；The ball cage type ten thousand
Lead to be interference fitted to section shell and be nested into the hole that wheel shaft processes in advance, the screw thread spacing ring and split pin are to ball cage type
Cardan joint housing progress is spacing, and the screw thread spacing ring is screwed on wheel shaft, and the wheel shaft respective regions are threaded；Institute
Hole insertion opening pin is got through on the screw thread spacing ring and wheel shaft stated；The semiaxis, clamp spring, planet carrier, ball, the ball of retainer
Installation is similar with DOJ type universal joints inside cage, and the cage for being already installed on wheel shaft is inserted into after installation is complete inside the cage
In the scalable raceway of formula cardan joint housing, it is spacing to add limit stop ring progress.
The axle system on described wheel side, wheel shaft is single part, adds overall structural strength, with ball cage type ten thousand
It is surface-treated to the position of section housing nests to reduce abrasion, the bottom lock at nested position limits rzeppa joint
Shell produces sliding.Wherein, rzeppa joint shell steel, processing technology can use wire cutting, and its inner surface is carried out
It is heat-treated to increase hardness, the housing processes limiting slot in side and is used for filling limit stop ring.The screw thread spacing ring
There is screw thread in inner side, coordinates with equally having threaded wheel shaft, the split pin passes through wheel shaft and screw thread spacing ring.The spiral shell
The effect of line spacing ring is spacing into row position to the bearing on wheel shaft outside diameter using its outside diameter；And prevent for cage
The groove position that dirt set fixing hoop reserves can be fastened directly to the portion.Screw thread spacing ring is done in the split pin further to be prevented
Pine processing.
The rzeppa joint inner body and semiaxis, wherein, retainer, ball, planet carrier are by having machined
Into cooperate installation, is then carried out with axis with clamp spring on the inside of planet carrier spacing after insertion semiaxis, puts it into ball cage type ten thousand
To the inside of section shell, complete to assemble plus limit stop ring, the follow-up dirt-proof boot that installs additional is fastened on screw thread spacing ring.
Compared with prior art, the beneficial effects of the invention are as follows.
（1）It is highly integrated.Highly integrated, the structure design conjunction of rzeppa joint and wheel shaft is realized by nested form
Manage compact, avoid traditional universal joint and take turns the locus of axis connection and the interference of suspension design, reduce that cooperation is overall to exist
The space that wheel side occupies, and universal joint caused by uneven road surface and road barrier can be avoided to collide with, improve reliability.
（2）High transmission efficiency.Spline fitted between traditional rzeppa joint and the axle system for taking turns side is eliminated to connect
Mode, using Nested design, reduces the loss of transmission efficiency；Contrasted with traditional form, half shaft length increases under equal wheelspan
Greatly, semiaxis angle reduces in frontal planar, and the semiaxis transmission efficiency of smaller can be brought to lose and more preferably suspension geometry upper angle
Gain.
（3）Lightweight.Each element size has the volume of smaller compared with conventional wheel cincture axle system and rzeppa joint,
Unsprung mass can greatly be mitigated using suitable material use, bring rotary inertia and the more excellent manipulation experience of smaller.
（4）It is spacing ingenious in design.The rzeppa joint shell and wheel edge system wheel shaft of cage universal joint process at the same time
Limiting slot installs the design of limit stop ring, can also prevent cage from being skidded off from raceway while being fastened to cage is nested；Inside has
The design of the reeded spacing ring of threaded exterior, is ensureing that it is on wheel edge system wheel shaft and reliably spacing to bearing that bearing can load,
Easy disassembly and maintenance and fixed cage dirt-proof boot are gone back at the same time.
（5）Have a extensive future.It cannot be only used for the automotive fields such as passenger car, commercial car, racing car, it may also be used for extraordinary machine
The fields such as tool, celestial body detecting vehicle, toy car.
