Description

The axial gearshift cover that is used for axial selector

Technical field

The utility model relates to automotive field, the selector parts on particularly a kind of Motor Vehicle.

Background technique

Present Motor Vehicle selector is generally the fork type selector, it includes power input shaft and pto, power input shaft is provided with low-speed active gear and high speed driving gear, and pto is provided with low speed driven gear and high speed driven gear.During work, by stirring shift fork low-speed active gear and power input shaft are fixed, this moment, Motor Vehicle was a bottom gear, or by shift fork high speed driving gear and power input shaft was fixed, and this moment, Motor Vehicle was a top gear.Its deficiency has: can only change at a high speed and between two gears of low speed, but distribution network be few because Motor Vehicle is shifted gears by the move left and right of shift fork (1); (2) minimum two axles and a plurality of gear of including of fork type selector, two axles are assembled together by the gear that is arranged on the axle, and required part is many, the cost of production height, assembling is inconvenient, and institute takes up space big.Based on above shortcoming, the technician has developed axial selector, and axially selector includes axial gearshift cover, axially gear level, mobile gearshift are sold and speed change gear.

Summary of the invention

The purpose of this utility model just provides a kind of axial gearshift cover that is used for axial selector with low cost, and it is enclosed within the transformation that can realize the many gears of Motor Vehicle on the axial gear level.

The purpose of this utility model is to realize that by such technological scheme it includes sleeve pipe, and sleeve pipe one end is fixed with the angle tooth, and the sleeve pipe sidewall is provided with and is used to install the pin-and-hole that moves the gearshift pin.

During use, axially inserting the axial gear level of being with boss in the gearshift cover, angle tooth and power mechanism engagement, power mechanism rotates by the moving sleeve pipe of angle cingulum, all is placed with to move the gearshift pin in pin-and-hole, and the gearshift pin is positioned at the space that axial gear level and pin-and-hole surround, on the outer wall of sleeve pipe, be with a plurality of speed change gears, the speed change gear inwall is fluted, and the quantity of groove is corresponding with position and pin-and-hole, and the quantity of speed change gear is corresponding with row's number of pin-and-hole.During gearshift, axially push-pull shaft is to gear level, the guide ring platform moves to a certain speed change gear position, the mobile gearshift pin that will be positioned at pin-and-hole ejects, make to move and shift gears pin between the groove and pin-and-hole of speed change gear, move the gearshift pin and make speed change gear and sleeve pipe become integral body, sleeve pipe can rotate together by moving this speed change gear of gearshift pin drive when rotating at this moment, this speed change gear is meshed with corresponding power output gear, and power output gear drives pto and carries out power output.Change when retaining, continue to twitch push-pull shaft, the speed change gear of next gear is fixed together with sleeve pipe and rotates to gear level.Because gearshift only need make different speed change gears with the fixing rotation of gearshift cover, so, can realize the gearshift of two retainings, three retainings, four retainings or many retainings by increasing a plurality of numbers of teeth speed change gear different with size.

The utility model can make the speed change gear and the cover of axially shifting gears well combine, thereby makes axial speed changer have following advantage: (1) supports the conversion of many gears; (2) compact structure; (3) with low cost.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As shown in Figure 1 and Figure 2, be used for the axial gearshift cover of axial selector, it includes sleeve pipe 1, and sleeve pipe 1 one ends are fixed with angle tooth 2, and sleeve pipe 1 sidewall is provided with and is used to install the pin-and-hole 6 that moves gearshift pin 5.As Fig. 6, shown in Figure 7, during use, in axially gearshift is overlapped, insert the axial gear level 8 of tape guide ring platform 7, angle tooth 2 and power mechanism 9 engagements, power mechanism 9 drives sleeve pipe 1 by angle tooth 2 and rotates, in pin-and-hole 6, all be placed with and move gearshift pin 3, gearshift pin 3 is positioned at the space that axial gear level 8 and pin-and-hole 6 surround, on the outer wall of sleeve pipe 1, be with a plurality of speed change gears 10, speed change gear 10 inwalls fluted 11, the quantity of groove 11 is corresponding with position and pin-and-hole 6, and the quantity of speed change gear 10 is corresponding with row's number of pin-and-hole 6.During gearshift, axially push-pull shaft is to gear level 8, guide ring platform 7 moves to a certain speed change gear 10 positions, the mobile gearshift pin 3 that will be positioned at pin-and-hole 6 ejects, make and move gearshift pin 5 between 10 grooves 11 and pin-and-hole 6 of speed change gear, moving gearshift pin 3 makes speed change gear 10 and sleeve pipe 1 become integral body, this moment, sleeve pipe 1 can rotate together by moving gearshift pin 3 these speed change gears 10 of drive when rotation, this speed change gear 10 is meshed with corresponding power output gear 12, and power output gear 12 drives ptos 13 and carries out power output.Change when retaining, continue push-pull shaft, the speed change gear 10 of next gear is fixed together with sleeve pipe 1 and rotates to gear level 8.Because gearshift only need make different speed change gears with the fixing rotation of gearshift cover, so, can realize the gearshift of two retainings, three retainings, four retainings or many retainings by increasing a plurality of numbers of teeth speed change gear 10 different with size.

Can be provided with two row's pin-and-holes 4 on sleeve pipe 1 sidewall, also can be provided with three row's pin-and-holes 4, also can be provided with four row's pin-and-holes 4, can also increase according to the demand of gearshift.

Every row's pin-and-hole 4 can include two on sleeve pipe 1 sidewall, laterally is evenly distributed on sleeve pipe 1 sidewall, and axially two adjacent pin-and-holes 4 are staggered.Every row's pin-and-hole 4 also can include three on sleeve pipe 1 sidewall, laterally is evenly distributed on sleeve pipe 1 sidewall, and axially two adjacent pin-and-holes 4 are staggered.Every row's pin-and-hole 4 also can include four on sleeve pipe 1 sidewall, laterally is evenly distributed on sleeve pipe 1 sidewall, and axially two adjacent pin-and-holes 4 are staggered.Every row's pin-and-hole 4 can also include a plurality ofly on sleeve pipe 1 sidewall, laterally is evenly distributed on sleeve pipe 1 sidewall, and axially two adjacent pin-and-holes 4 are staggered.The number of every row's pin-and-hole 4 is corresponding with the groove on the speed change gear on sleeve pipe 1 sidewall.
