Embodiment
First, it should be noted that, concrete structure, the feature and advantage etc. of anti-off-gear self-locking mechanism of the present utility model and synchronizer, manual transmission and vehicle will be illustrated by way of example below, but all descriptions are only used to be described, and should be understood as any restriction is formed to the utility model.In addition, described or implicit any single technical characteristics in each embodiment mentioned by herein, or be shown or implicit any single technical characteristics in the drawings and in which, still can between these technical characteristicss (or its equivalent), proceed combination in any or delete, thus obtain other embodiments of the present utility model more that may directly not mention in this article.
Occur that the orientation term such as up, down, left, right, before and after, front, the back side, top, bottom that maybe may occur carries out defining relative to the structure shown in each accompanying drawing in this manual, they are relative concepts, therefore likely can residing for it diverse location, different using state and correspondingly changing.So, also these or other orientation term should be interpreted as restricted term.In addition, in order to simplify for the purpose of drawing, identical or similar technical characteristics may only indicate at a place in the same figure.
As shown in Figure 1, illustrate schematically the stereochemical structure that is equiped with the synchronizer according to anti-off-gear self-locking mechanism embodiment of the present utility model in the figure.Comprise the tooth cover 1 and tooth hub 3 that match each other at this synchronizer, spline mode can be adopted realize cooperation therebetween, on tooth hub 3, evenly install three from lock set 2 along its circumference simultaneously.
Please also refer to Fig. 2 to Fig. 7, each comprises pedestal 20, counterpart 21 and link 4 from lock set 2.As shown in Figures 2 and 3, for pedestal 20, it is as the foundation in lock set 2, and has body 22, department of assembly 25 and elastic support portion 24, wherein on body 22, offer mounting hole 26, and offer mounting hole 23 in department of assembly 25.By link 4 is sleeved in mounting hole 23, and pedestal 20 can be installed on the periphery of tooth hub 3 of synchronizer via department of assembly 25.
As an example, can as Fig. 2, shown in Fig. 3 and Fig. 4, be arranged to department of assembly 25 alternatively have the first baffle plate 251 and second baffle 252 that are separately positioned on body 22 both sides, pedestal 20 is connected on the periphery of tooth hub 3 by these baffle plates, such as clamping is arranged in the groove 32 on tooth hub 3 periphery, then can adopt as the rivet parts as link 4 shown in Figure 4, by these type of rivet parts being passed the mounting hole 31 on mounting hole 23 and tooth hub 3, then by the head 41 of pressed rivet parts, pedestal 20 riveted joint is fixed on the periphery of tooth hub 3 of synchronizer.
In the example given, counterpart 21 is shown as forming spheroid form, by the metallic material such as steel, iron can be adopted to make, to ensure that it possesses good wear resistance and non-deformability.But, in the utility model, also allow suitable shape counterpart 21 being made other according to application needs.
In lock set 2, counterpart 21 is installed in pedestal 20, the elastic force that it accepts the elastic support portion 24 in pedestal 20 and provides supports, and under the effect of this elastic force, make a part for counterpart 21 expose mounting hole 26, thus the internal spline making this expose portion can overlap 1 with the tooth of synchronizer is conflicted mutually, just can provide self-locking action power to prevent thus when tooth cover 1 occurs off-gear phenomenon when keeping off.
Under optional situation, as shown in the embodiment that this provides, the elastic support portion 24 in pedestal 20 can be configured to elastic cantilever structure, illustrate this structure with half section perspective view form in figure 3.As shown in Figure 3, in this exemplary elastic cantilever structure, it has first portion 241 and second portion 242, and these two parts are separated from each other and are arranged symmetrically with.As an example, spring steel material can be adopted integrated with body 22 for above-mentioned elastic cantilever structure impact briquetting.Then, by in counterpart 21 also integrated installation to pedestal 20 and between the first portion 241 be arranged in elastic cantilever structure and second portion 242, with the support making it accept the elastic force applied by first portion 241 and second portion 242 respectively on both sides.The resilient engagement effect therebetween of counterpart 21 and elastic cantilever structure, counterpart 21 can be made along with the change of radial displacement to produce a radial force, and this radial force can keep approximately linear to change in certain displacement range.
More specifically, such as consult shown in Fig. 7, after synchronizer is linked into N gear, by the sectional structure provided in figure, the visible pedestal 20 from lock set 2 is fixed on the tooth hub 3 of synchronizer by link 4, counterpart 21 acts on the inclined-plane 11 on the internal spline of the tooth cover 1 being arranged on synchronizer, the elastic support portion 24 of pedestal 20 will produce a corresponding radial force due to the change in displacement being subject to counterpart 21, reaction force then can act on inclined-plane 11, tooth can be made to overlap 1 by this reaction force and obtain an axial confining force, thus prevent synchronizer to trip stop.For above-mentioned inclined-plane 11, desired self-locking action power can be obtained by the parameter such as inclination angle, length adjusting this inclined-plane 11.
Anti-off-gear self-locking mechanism provided by the utility model has the plurality of advantages such as compact structure, compatibility is good, practical, reliability is high, by being integrated with spring function without the need to additionally arranging elastic element, and it is easy to install location, especially reliable self-lock force can be provided to guarantee that the tooth of synchronizer is enclosed within gear, thus effectively prevent speed changer and trip stop.
Because the synchronizer having installed this anti-off-gear self-locking mechanism has possessed auto-lock function, therefore tooth cover can without the need to adopting shift fork spacing, again by coordinating shifting system to adopt Decoupling design, just effectively can solve tooth cover, with shift fork, the axial vibration of axle system being delivered to the problem such as drag-line and gear.For the improvement of existing gearbox or the limited power assembly space of axial space, only slightly need do design alteration and can apply anti-off-gear self-locking mechanism of the present utility model the tooth hub of synchronizer, tooth cover, and effectively prevent from trip stopping in conjunction with the method for length without the need to what adopt increase to overlap in conjunction with tooth and tooth again, therefore not only quick, with low cost, and be highly susceptible to realizing.Therefore, be applicable to very much anti-off-gear self-locking mechanism installing of the present utility model to be applied on various types of synchronizer, manual transmission and vehicle.
Be enumerated above some specific embodiments and illustrate anti-off-gear self-locking mechanism of the present utility model and synchronizer, manual transmission and vehicle in detail, this a few example is only for principle of the present utility model and mode of execution thereof are described, but not to restriction of the present utility model, when not departing from spirit and scope of the present utility model, those of ordinary skill in the art can also make various distortion and improvement.Such as, in the aforementioned embodiment, in anti-off-gear self-locking mechanism, be provided with three from lock set 2, and they be distributed on the tooth hub 3 of synchronizer, but the utility model also allows to select neatly to arrange the concrete layout quantity, mounting point etc. from lock set 2 according to practical situations.For another example, in citing above, counterpart 21 is that the inclined-plane 11 by acting on tooth cover 1 provides axial self-locking power, but also can be arranged non-ramp structure and born this axial self-locking power by the internal spline of the tooth cover 1 at synchronizer.Therefore, all equivalent technological schemes all should belong to category of the present utility model also by every claim of the present utility model is limited.
