Abstract

The utility model discloses a synchronizer sliding sleeve. The synchronizer sliding sleeve is arranged on a synchronizer, and comprises a combination sleeve and an inner spline arranged on the inner side of the combination sleeve, wherein the front and back ends of the inner spline are provided with locking corners; the locking corners extend out of the combination sleeve. By adopting the synchronizer sliding sleeve, a locking function can be realized, and the axial space is not occupied.

Description

A kind of synchronizer sliding sleeve

Technical field

The utility model belongs to a kind of sliding sleeve, is specifically related to a kind of synchronizer sliding sleeve.

Background technique

In speed changer structure design more and more compacter today, designer will constantly reduce the weight, the compacter installing space of design of part to pursue higher specific power under the constant condition of speed changer input torque.In order to reduce the power of putting into gear, reduce driver's labor intensity, most speed changer uses synchronizer to shift gears, conventionally the effective length of the internal spline soldered tooth on synchronizer sliding sleeve is identical with the width of synchronizer sliding sleeve, realize synchronous mobile putting into gear before in order to stop to slide over, produce ring moment simultaneously, spline increment at synchronous conical ring and sliding sleeve will process angle of lock, sliding sleeve and the seat length in conjunction with gear ring are so just reduced, owing to not participating in the transmission of moment in the time that sliding sleeve engages with synchronizing ring in conjunction with tooth angle of lock part, although but the design of existing angle of lock can be played the effect of locking, but take axial space.

Model utility content

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of synchronizer sliding sleeve is provided, and this sliding sleeve can be realized the function of locking, and axial occupation space not.

For achieving the above object, synchronizer sliding sleeve described in the utility model is installed on synchronizer, comprises combined cover and is located at the internal spline of combined cover inner side, and on the rear and front end face of internal spline, be equipped with angle of lock, angle of lock extends to outside the end face of combined cover.

The angular range of described angle of lock drift angle is 90 °～130 °.

The bottom of described angle of lock and the end face of combined cover.

The utlity model has following beneficial effect:

Synchronizer sliding sleeve described in the utility model comprises combined cover and is located at the internal spline of combined cover inner side, internal spline rear and front end is provided with angle of lock, angle of lock extends to outside the end face of combined cover, thereby in the situation that synchronizer engage a gear stroke is constant, effectively increase synchronizer sliding sleeve and the length of action in conjunction with gear ring, alleviate the weight of synchronizer sliding sleeve simultaneously, thereby reduce the rotary inertia of synchronizer, in addition, angle of lock is extended to outside combined cover, be easier to processing.

Wherein, 1 is that synchronizer sliding sleeve, 2 is to be that angle of lock, 4 is internal spline in conjunction with gear ring, 3.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

With reference to figure 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, synchronizer sliding sleeve 1 described in the utility model is installed on synchronizer, comprise combined cover and be located at the internal spline 4 of combined cover inner side, on the rear and front end face of internal spline 4, be equipped with angle of lock 3, angle of lock 3 extends to outside the end face of combined cover, the angular range of angle of lock 3 drift angles is 90 °～130 °, the bottom of angle of lock 3 and the end face of combined cover.

Concrete mounting point of the present utility model is:

As shown in Figure 7, on the combination gear ring 2 of synchronizer assembly, be with the positive stop lug boss of putting into gear, the stroke of putting into gear of synchronizer is the A end face of synchronizer sliding sleeve 1 and in conjunction with the distance between the positive stop lug boss B end face of gear ring 2, the stroke formula of putting into gear can be expressed as S=(c-d)/2-e, synchronizer sliding sleeve 1 be a in conjunction with the mesh regional of gear ring 2.

Synchronizer sliding sleeve 1 provided by the utility model stretches out synchronizer sliding sleeve 1 in conjunction with angle of lock 3 parts of tooth, because angle of lock 3 parts do not participate in engagement when engaging in conjunction with gear ring 2 at synchronizer sliding sleeve 1, not carry-over moment, the width of angle of lock 3 is b, so, common sliding sleeve and the length that is mesh regional a in conjunction with effective length of action of gear ring 2 deduct the width b of angle of lock 3, are (a-b).Compared with common sliding sleeve, put into gear stroke S constant in the situation that at synchronizer, the synchronizer sliding sleeve 1 that angle of lock 3 stretches out be the length of mesh regional a in conjunction with effective length of action of gear ring 2, be a.

In the situation that other part of synchronizer is constant, the angle of lock of synchronizer sliding sleeve 13 parts are stretched out outside synchronizer sliding sleeve 1, compared with common sliding sleeve, can increase gearshift stroke, be beneficial to and reduce the power of putting into gear.Can reduce the weight of synchronizer sliding sleeve 1, thereby reduce the rotary inertia of synchronizer, reduce the power of putting into gear.
