Description

Shifting controller for hand transmission

The present invention relates to a kind of shifting controller for hand transmission, relate in particular to a kind ofly except that the gear-change operation process,, all can prevent from the vibration of change-speed box is passed to the shift controller of shifter bar by avoiding physics to contact with the gear state of changing at neutral state.

Fig. 1 shows a kind of traditional shifting controller for hand transmission.

In Fig. 1, in case shifter bar 51 is handled, the actuating force of shifter bar is sent to actuating spindle 53, and the pin 55 of actuating spindle 53 1 ends engages with gear shift gear hanger 59 on the gear shift ail 57 like this, makes actuating force be delivered to gear shift ail 57.

Gear shift ail 57 other ends have a plurality of control forks 61, and control fork 61 moves with the sleeve of synchronous device (not shown) and carries out gear-change operation.

And gear shift ail 57 has the lifting valve ball 67 in the bacterium shape groove 63 of being fastened on of a plurality of lifting valve pools 63 and respective numbers, promotes valve ball by spring 69 resilient mountings.This structure can produce a kind of locking effect when gear shift ail 57 operations.

In this traditional shift controller, between each element, between shifter bar, actuating spindle, the gear shift ail,, all be mechanical connection for example for the operation control fork.Like this, change-speed box inside causes shift quality to reduce because of vibration and the friction that gear-change operation causes can be directly delivered to shifter bar.

The present invention is intended to solve the aforementioned problems in the prior

It is a kind of by no physics contact between inner member that the object of the invention is to provide, realize except that the gear-change operation process, all can prevent from the vibration between the change-speed box inner member and improper friction are delivered to the shift controller of shifter bar at neutral state or the gear state that changes to.

To achieve these goals, shifting controller for hand transmission among the present invention comprises that one is used for the shifter bar of operation transmission, be connected the actuating spindle of above-mentioned shifter bar lower end, from the vertically outstanding pin of actuating spindle, gear shift ail stretches in its hanger by the pin with actuating spindle and is connected with actuating spindle, first Locking Device is between gear shift ail and case of transmission, for gear shift ail provides the locking operation, second Locking Device is between actuating spindle and case of transmission, for actuating spindle provides the locking operation.

Accompanying drawing is the part of book as an illustration, shows one embodiment of the present of invention, and they explain principle of the present invention with describing part.

Below with reference to accompanying drawings the preferred embodiments of the present invention are described in detail.

Fig. 2 is the Operation Profile figure of shifting controller for hand transmission of the present invention at neutral state.

Among Fig. 2, shift controller of the present invention comprises: an actuating spindle 3, a pin 1 is arranged on the actuating spindle, and actuating spindle one end is connected with the shifter bar (not shown); One gear shift ail 5 has a hanger 7 to be used for holding the pin 1 of actuating spindle 3 on it; The control fork 9 that one sleeve 11 of one and one synchronous device 13 is connected.Like this, the actuating force of shifter bar can be delivered to the sleeve 11 of synchronous device 13 from shifter bar, so that handle sleeve 11.

First Locking Device be used to provide the locking operation, and second Locking Device is between actuating spindle 3 one sides and case of transmission 17 between gear shift ail 5 one sides and case of transmission 17.

First Locking Device comprises that 3 lifting valve pools 15, that are positioned at gear shift ail 5 upper surfaces promote valve balls 21, and are installed in the spring 23 that is used for compressing lifting valve ball 21 in the receiver hole 19.Promote valve ball 21 and be landed on the aperture of case of transmission 17 respective surfaces receiver holes 19, promote valve ball 21 like this and be located between lifting valve pool 15 and the receiver hole 19.

Second Locking Device comprises 3 lock grooves 25 that are positioned at actuating spindle 3 upper surfaces, one locking ball 29, locking ball 29 is landed on the aperture of receiver hole 27 on case of transmission 17 respective surfaces, one is installed in the spring 31 that is used for compressing locking ball 29 in the receiver hole 27, and the locking ball is located between lock groove 25 and the receiver hole 27 like this.

The pin-and-hole that has an opening that is used for holding the pin 1 on the actuating spindle 3 to make progress on the hanger 7 is so that hanger 7 engages with actuating spindle 3.Hanger 7 should constitute by this way with pin 1.That is, when hanger 7 engages with pin 1, there are gap P1 and P2 at hanger 7 inside faces and pin 1 outside face.First, second Locking Device in gearshift procedure at three state of operation.

Gap P1 and P2 are determined that by the Oscillation Amplitude in the change-speed box vibration in the change-speed box just can not passed to actuating spindle 3 like this.

The shifting controller for hand transmission operating process of said structure will be described with reference to Fig. 3, Fig. 4 and Fig. 5 hereinafter.

Fig. 3, Fig. 4 and Fig. 5 are respectively first, second and the 3rd serviceability section-drawings of shift controller of the present invention.

At first state, in case the shifter bar (not shown) is handled, the gear that the neutral state to from Fig. 2 is predetermined, the pin 1 on the actuating spindle 3 move in the scope of gap P1 and P2, and can mobile gear shift ail 5, as shown in Figure 3.

At second state, shifter bar is further handled, and pin 1 moves to the state of contact hanger 7, and like this, the actuating force of shifter bar just is sent to gear shift ail 5 (see figure 4)s.Accordingly, the control fork 9 on the gear shift ail 5 moves the sleeve 11 of synchronous device.

In this case, the lock groove 25 on the locking ball 29 touch controls axles 3, like this, the motion of actuating spindle 3 is with regard to the obstruction of the outshot that is subjected to forming lock groove 25 and produce the locking effect.At this moment, bacterium shape ball 21 is not positioned at the bacterium shape groove 15 of gear shift ail 5 fully.

In the third state, as shown in Figure 5, bacterium shape ball 21 is subjected to the resilient force of spring 23 and is positioned at bacterium shape groove 15 fully, gear shift ail 5 is moved and finishes the working process of synchronous device 13.

As mentioned above, shifting controller for hand transmission of the present invention, because when pin 1 and hanger 7 engage, there are gap P1 and P2 between the inside face of the hanger 7 on the gear shift ail 5 and pin 1 outside face on the actuating spindle 3, can prevent that the caused vibration of change-speed box from passing to shifter bar, can also avoid producing improper friction, thereby shift quality is improved.

Be considered to the most practical and preferred embodiment at present though the invention describes, be interpreted as the present invention and be not only limited to the disclosed embodiments, on the contrary, consider to be included in design and the various modification in the scope and the equivalent device of following claim.
