Description
Technical field
The utility model is a kind of vehicle speed variation hub, especially refers to a kind of speed change hub weight and joint space-efficient vehicle speed variation hub of alleviating.
Background technique
Be provided with a gearshift mechanism in the engine of type motor vehicle entirely, described gearshift mechanism comprises a crankcase and a transmission case that is connected with crankcase, this crankcase comprises a shift shaft, a speed change hub, positioning piece, a pull-fork assembly and a shifting gear assembly, wherein, this shift shaft connects the speed change hub, coordinate and be connected in pull-fork assembly in this speed change hub and locating piece start, and pull-fork assembly further connects the shifting gear assembly.
This shift shaft is provided with a change gear, as shown in Figure 7, this speed change hub 20 comprises an axostylus axostyle 21, a cam member 26 and an actuation gear 27, this axostylus axostyle comprises a body 211 and is divided into the first bar section 212 and the second bar section 213 of body 211 biends, this cam member 26 and actuation gear 27 are located at the first bar section 212 and the second bar section 213 with its shaft hole sleeve respectively, this actuation gear 27 is to wear the one side with a positioning rod with departing from its axis hole, and with it be fixed in body 211 sides and with shift shaft on change gear engagement; The speed change groove 24 that on this body 21, positioning groove 22, one first speed change groove 23, the one and first speed change groove 23 of the plural annular arrangement of formation are distributed in distance, and the through hole 25 between the first speed change groove 23 and the second speed change groove 24, described positioning groove 22 is positioned at an end that is adjacent to actuation gear 27 on body 211, be for locating piece 30 with an end of its tool location ball 31 against wherein.
The change gear that sees through shift shaft can guide actuation gear 27 runnings, the axostylus axostyle 21 of speed change hub 20 is rotated thereupon, and utilize the first speed change groove 23 that forms on axostylus axostyle 21 different from the distance of the second speed change groove 24 each points, and can change the relative position of two shift forks that pull-fork assembly comprises, and then the gear shift operation of control shifting gear assembly, in order to the running speed of switch engine.
in right above-mentioned, the positioning groove 22 that matches with locating piece 30 on this speed change hub 20 is to see through machining tool general's cutting forming in body 211 sides of axostylus axostyle 21, but make positioning groove 22 produce one section invalid 221 with respect to the other end of actuation gear 27, described invalid 221 and the second speed change groove 24 whole segment distance between invalid 221, make change gear coordinate the position of actuation gear 27, what need more in fact need is far away, the shared volume of engine housings body is also larger, hence one can see that, the second speed change groove 24 to invalid one section space not only can't provide any effect to whole gear shift operation, weight and the volume of car engine have also been increased.
another with reference to " gearbox shifting position signal extractor " Patent Case as TaiWan, China letters patent book number 165387, see also the shown in Figure 4 of this Patent Case, it is also to see through shift cam to drive the rotation of speed change hub, and utilize cam groove integrally formed on the speed change hub to control the start of shift fork pivot, and then affect the running of driving tooth wheels, yet, for making the speed change hub utilize bearing to rotate, need the another one section axle portion that increases between shift cam and speed change hub, and be connected in shift cam with this axle portion with respect to the other end of speed change hub, can find because of this shift cam and the non-closely closing of speed change hub, and inactive area is not omitted in the mode of simplifying most on the speed change hub, still cause the overall space waste and increase on foot meaningless weight.
The model utility content
Main purpose of the present utility model is to provide a kind of vehicle speed variation hub, and uncommon model utility is by this improved present speed change hub and increased on foot some unnecessary volume or weights, the problems such as the volume of result increase engine integral body and weight.
Take off purpose for before reaching, the utility model vehicle speed variation hub is that it comprises in order between the change gear and pull-fork assembly that are arranged at the Vehicular shift axle:
The first bar section and the second bar section that one axostylus axostyle, this axostylus axostyle comprise a body and be located at respectively the body biend form the second speed change groove that one first speed change groove, the one and first speed change groove are distributed in distance on this body;
The first bar section that one cam is sheathed and be fixed in axostylus axostyle;
One location cam, it has the positioning groove of one first axis hole and plural annular arrangement, and this positioning cam is with sheathed the second bar section of being fixed in axostylus axostyle of its first axis hole; And
One actuation gear, it has one second axis hole, this actuation gear is with in its second axis hole sheathed the second bar section of being fixed in axostylus axostyle and be positioned at the positioning cam outside, this actuation gear in order to described change gear engagement.
According to an aspect of the present utility model, the end face that this positioning cam and body are provided with the second bar section contacts, this positioning cam has the first perforation outside being positioned at the first axis hole, this actuation gear is positioned at the second axis hole outside and has second perforation corresponding to the first perforation, and a side of the body of this axostylus axostyle contiguous the second bar section has one corresponding to the first perforation and biperforate fixed hole; Described speed change hub sequentially wears the second perforation of actuation gear, the first perforation of positioning cam and the fixed hole of body with a positioning rod, and positioning cam is fixedly arranged between body and actuation gear.
