Description

Combined half-axle with function of sliding and oil-saving

The present invention relates to a kind of combined half-axle with function of sliding and oil-saving

The flanged dish of semiaxis one end of power actuated vehicle is connected with wheel hub, and the other end has pattern chain, is connected with differential gear, this combined half-axle is that the flange portions of semiaxis is improved, make semiaxis that wheel function be arranged, realize fuel-economizing, therefore real is a sliding fuel-saving device.

Existing vehicle sliding fuel-saving device, be to separate with semiaxis, independent groups is combined into parts, volume is very big, height is suitable with the flange diameter, therefore dilly can't be installed, and existing vehicle sliding fuel-saving device all is that two groups of ratchet and pawl arrangements are arranged, one group of forward is used for vehicle to overtake, and oppositely directed one group is used for reversing and these two groups of ratchet and pawl arrangements, one group is at the end near lid, one group is near wheel hub, and with sliding one group of ratchet profile of tooth is arranged respectively on the core at shell, and for example patent No. CN87208316U is exactly this structure; And number of patent application 902226223 has proposed the structure of compound handle ratchet wheel pawl type structure and roller overrunning clutch formula; All gliders all are two-layer.One deck mechanism realizes advancing, and one deck mechanism is used for reverse gear, and never on identical cross section, a garden, structure is all very complicated in two-layer mechanism, and reliability is low; Super-clutch type causes and skids because roller and raceway wear and tear, and is very dangerous; Existing this type of glider has only a cover advancement mechanism, and after the damage, vehicle just can not have been worked, so all can not large-scale popularization use so far.

The objective of the invention is to overcome existing vehicle skid, volume is big, can only be contained on the truck, the shortcoming that can not install on the dolly, and accomplish behind the board can be freely cruising, guarantee to quicken continuously, can the actv. reversing, under rated speed of rotation, open cunning in the driving process automatically, on-slip automatically; Also can realize artificial locking in case of necessity; Simplified structure energetically improves intensity in addition, improves service life, and two cover advancement mechanism are particularly arranged, and a cover reverse gear mechanism has improved safety.

This combined half-axle with function of sliding and oil-saving remains on the semiaxial position that is contained in motor vehicle drives axle and wheel hub connecting portion, by formations such as lid, shell, semiaxis, clutch block, support claw (or roller), spring device, bearings; This vehicle skid has the square breach that clutch block is installed and moved on shell, built-in spring and clutch block, and this clutch block can enter semiaxis smoothly, or under centrifugal action, partly or entirely ensconces in the v notch v of shell top; Certain angle staggers on cross section, same garden simultaneously, have the track of support claw (or roller) motion, the curve of track is, in the suitable direction of arrow and support claw (or roller) contact site, microcephaly's radius of its R and support claw quite (or suitable with the roller radius) can stop support claw (or roller) to advance; And press the reversing sense of arrow, and there is a curve that the garden is crossed along slipping over, its function is that the support claw (or roller) that makes smooth-going when sliding enters in the breach of semiaxis; In semiaxis, press on corresponding angle of shell and the cross section, garden, also have the square breach that clutch block can enter and withdraw from, this breach will pruned one along the direction of arrow, (by truncated section, a non-metallic material can be pasted in the surface) make both sides that individual jump be arranged, this jump can be realized sliding automatically, moves backward and makes functions such as vehicle advances; Simultaneously in the cross section, identical garden of semiaxis, also have support claw (or roller) on the different angles, install and the breach of motion, its function is a vehicle when advancing, and power is pushed down support claw (or roller) by semiaxis press to the shell drive wheels again; Eliminate transmission of power, vehicle art skating under the force of inertia effect when sliding.Breach alternate arrangement in cross section, same garden of the square breach of clutch block motion and support claw (or roller) motion in shell and the semiaxis, each one at least of quantity is good respectively to be two or three.

Advantage of the present invention is that coasting mechanism and semiaxis are combined as independently parts, it is become can be supporting with the vehicle of batch manufacturing, also can be contained in and have now on the various vehicle of usefulness, especially volume is very little, not only can be contained on the truck but also can use on dilly; Advantage structurally is by support claw (or roller) vehicle is advanced, and the utilization clutch block not only can be realized sliding automatically, automatically on-slip, reversing, simultaneously vehicle is advanced, and promptly advancing has two cover mechanisms; This two covers mechanism is all in cross section, a garden, and therefore simple in structure, handling ease, reliability are big.

Fig. 1 has the constructional drawing of function of sliding and oil-saving combined half-axle

Fig. 2 is the cutaway view of Fig. 1

Fig. 3 support claw and spring assembly figure

Fig. 4 is semiaxis part figure in addition

Be described further with reference to the accompanying drawings:

Among Fig. 1 and Fig. 2,1 is lid, 2 bearings, 3 clutch blocks, 4 springs, 5 shells, 6 semiaxis, 7 support claws (accompanying drawing 2b is a roller), 8 spring devices, 9 bearings, 10 oil sealings, the installation site of not shown semiaxis; Fig. 2 a clearly shows clutch block, the curve of support claw and several breach, geometric figure among the b, position and relation, semiaxis 6 and shell 5 among the figure, clamped support claw 7, this moment, clutch block entered under the spring force effect in the square breach of semiaxis, and the size of this breach is greater than clutch block, make both sides that tangible gap all be arranged, when not reaching coasting speed when vehicle take-offs, transmission of power is to semiaxis, and by support claw shell rotated, because of shell links to each other with wheel hub, so vehicle to overtake; When moving velocity reaches automatic coasting speed (the supposition design is decided to be 40Km/h), clutch block under centrifugal action, overcome spring force in shell indentation greater than the distance of H, if power disappearance this moment (driving engine cut-offs and reduces to idling), semiaxis is almost motionless, shell does not have again under the situation of mechanical resistance and moves on then under the effect of force of inertia; This moment, support claw was pressed in the breach of semiaxis by the curve of shell, clutch block then advances along the direction of arrow along the high low step of semiaxis breach H, constantly cross the breach that support claw hides oneself and skip the square breach of semiaxis and slide, because the rotating speed of the resistance wheel of road slowly gets off, centnifugal force is also along with reducing, when reaching the regulation rotating speed, clutch block enters in the breach of semiaxis under the spring force effect again; Stop sliding automatically of no mechanical resistance; If acceleration continuously needs only open the throttle wide, because of among the moving circle of wheel revolution, support claw always has an opportunity under the promotion of spring device 8 part to be entered in the shell, can be clamped by semiaxis and shell in case power just transmits in this process; If reversing, this moment, rotating speed was very low, and clutch block necessarily enters in the semiaxis, when semiaxis its breach (one side that H is high) that reverses has blocked clutch block, and drove shell and wheel reversing; If vehicle is in operation support claw crushing or spring device inefficacy have taken place, support claw can't get out in breach, and clutch block can be given shell and wheel with transmission of power by clutch block by the semiaxis jam-packed at this moment, and vehicle is advanced.

Fig. 1 can know and find out that all within cross section, same garden, this is and the most tangible difference of various gliders the various breach of clutch block and support claw.

Fig. 2 is the cut-away view of Fig. 1, and a is one of embodiment for using support claw; B is two of embodiment, uses roller, and its principle is identical with job procedure, is to substitute support claw with roller among the b, and semiaxis with matching also has the R garden cambered surface similar to roller with shell; Semiaxis rotates shell to drive tire by roller and advances during transferring power; When sliding, roller is pressed in the breach of semiaxis by the shell curve.

Fig. 3 is support claw and spring assembly figure, a occupies the less hole of several diameters by the direction of cutaway view, has inserted a spring wire that energy is blocked by the hole in each hole, makes support claw that an outside power be arranged, guarantee outwards to open, because the spring long-term work easily produces fatigue, fracture appears, take many combinations, strained condition is different, can increase the service life greatly, and avoid unnecessary and may produce looseningly, other that break down are part in addition; B is also passable with spring or other spring leafs.

Fig. 4 is a semiaxis, cutaway view a joins support claw, and b joins roller, and this semiaxis and diff junction remain spline, and the other end does not have flange, with cross section, the corresponding same garden of shell on interleaved the square breach that clutch block can enter and the breach of support claw (or roller) motion arranged.

The design has groove on clutch block, bossing is arranged on the lid, has just realized artificial locking in the groove when the rotation lid enters bossing.
