Abstract
The invention discloses an interlocking device for a transfer case operation mechanism. The interlocking device comprises a front axle shifting fork shaft, a gearshift shifting fork shaft and a mounting base. A stripped groove is formed in one side, facing the front axle shifting fork shaft, of the gearshift shifting fork shaft. A high-gear self-locking groove, a first interlocking groove and a low-gear self-interlocking groove are sequentially formed in the other side of the gearshift shifting fork shaft. A circular arc-shaped groove is formed in one side, facing the gearshift shifting fork shaft, of the front axle shifting fork shaft. A second self-locking groove and a second interlocking groove are sequentially formed in the other side of the front axle shifting fork shaft. An interlocking pin is arranged at the stripped groove. The interlocking device adopting the scheme has the effects that the stripped groove is formed in the gearshift shifting fork shaft, the circular arc-shaped groove is formed in the front axle shifting fork shaft, and the interlocking pin is arranged between the gearshift shifting fork shaft and the front axle shifting fork shaft, so that the requirements that a transfer case can not be in a low gear before connection with a front axle, and must be out of the low gear when the front axle is disconnected are satisfied. Besides, the interlocking device adopting the scheme is simple in structure.
Description
Technical field
The present invention relates to transfer case, be specially a kind of interlock of transfer case operating device.
Background technique
Transfer case is mainly used in how shaft-driven offroad vehicle, its input shaft is direct or be connected with transmission main shaft by universal driving device, the Main Function of transfer case is to each ransaxle by the power distribution of speed changer output, when transfer case has two gears, transfer case has also been held concurrently the effect of auxiliary transmission.
Because transfer case Driving Torque when changing down is larger, for in avoiding, back axle overload, the operating device of transfer case must ensure first to connect propons before changing down, first low grade should be exited when taking propons, namely the operating device of transfer case should have interlocking function, the baroque problem of interlock ubiquity of the transfer case operating device used at present.
Summary of the invention
The invention is intended to the interlock that the simple transfer case operating device of a kind of structure is provided.
The interlock of the transfer case operating device in this programme, comprise propons declutch shift shaft, selector fork axle and fitting seat, the propons declutch shift shaft kink parallel up and down with selector fork axle is in fitting seat, selector fork axial plane offers strip groove to the side of propons declutch shift shaft, the opposite side of selector fork axle is provided with high-grade self-locking groove successively, first interlock recess and low-grade self-locking groove, two ends corresponding high-grade self-locking groove and first interlock recess respectively of strip groove, propons declutch shift shaft offers arc groove towards the side of selector fork axle, the opposite side of propons declutch shift shaft is provided with the second self-locking groove and the second interlock recess successively, arc groove and the second self-locking groove lay respectively at the corresponding position of front shelves declutch shift shaft both sides, strip groove place is also provided with interlocking plunger.
The principle of this programme is: when carrying out transfer case operation, when not connecting propons, under the effect of interlocking plunger, selector fork axle can only move along strip groove, access top gear, and access bottom gear can not be moved round about, ensure that and do not hang the requirement that propons can not access bottom gear, after by propons declutch shift shaft access propons, interlocking plunger is squeezed in arc groove in strip groove, now selector fork axle can along strip groove direction access top gear, also bottom gear can be accessed in opposite direction, when propons taken by needs, the strip groove of selector fork axle must be made to aim at arc groove, and two limit positions corresponding to strip groove are respectively high speed self-locking groove and the first interlock recess, when namely taking propons, selector fork axle can not be positioned at low speed self-locking groove, thus meet the requirement must exiting bottom gear when taking propons.
The effect of this programme is: by arranging strip groove on selector fork axle, propons declutch shift shaft arranges arc groove, and interlocking plunger is set between, ensure that transfer case is not hung propons and can not be accessed bottom gear, must exit the requirement of bottom gear when taking propons, the interlock structure of this programme is simple simultaneously.
Further, interlocking plunger two ends are arc-shaped structure, and arc-shaped structure can increase the surface of contact with groove, ensure the reliability of interlock.
Further, in order to effectively limit the position of front shelves declutch shift shaft and selector fork axle, also comprise the first steel ball being positioned at the first interlock recess side and the second steel ball being positioned at the second interlock recess side, the first steel ball place is also provided with the first stage clip, and the second steel ball place is provided with the second stage clip.
Further, adjustment first stage clip conveniently and the active force of the second stage clip, the first stage clip place is also provided with the first bolt, and the second stage clip place is also provided with the second bolt.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
