Description
Technical field
The utility model relates to the shifting structure, particularly a kind of new A MT gear shift mechanism that automobile is used the AMT gearbox.
Background technique
In the existing hydraulic pressure shifting operation mechanism, the block selecting process is the axial translation of block selecting axle, and the gearshift action is by the rotation realization of block selecting axle.Suppose that block selecting axle axis is Z axis, then the block selecting action is the Z-direction translation, and the gearshift action is the Z-direction rotation.And for the gearbox that adopts direct manipulation formula gear shift mechanism, hydraulic actuator can not directly be realized the shifting action by control block selecting axle.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of new A MT gear shift mechanism is provided, and makes hydraulic actuator realize the shifting of cane type shift device is controlled.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of new A MT gear shift mechanism is characterized in that: comprise block selecting oil cylinder, shift cylinder, block selecting shifting block and gearshift shifting block; The piston of block selecting oil cylinder is the block selecting piston, and the piston of shift cylinder is range piston; Be fixedly mounted with the slide block shift fork in the bottom of described block selecting piston, between this slide block shift fork, be fixedly mounted with a driving lever, this driving lever slip plug-in mounting enters in the made block selecting shift fork of described block selecting shifting block one end, and the made block selecting sliding sleeve of the other end of block selecting shifting block is fixed on the gearbox shifting axle by elastic cylindrical pin; At the made gearshift sliding sleeve of gearbox shifting axle described gearshift shifting block one end of suit, the other end of gearshift shifting block clamps with the range piston of described shift cylinder and is connected.
And the gearshift sliding sleeve that described gearshift shifting block is set in shifting shaft partly is flush-mounted in position between the block selecting sliding sleeve that the block selecting shifting block is sleeved on shifting shaft.
And described gearshift shifting block is shaped with cylindrical projection in the outside vertical that it is shaped with an end of gearshift sliding sleeve, made groove slip setting-in in this cylindrical projection and the gear box casing.
Advantage of the present utility model and good effect are:
New A MT gear shift mechanism of the present utility model, scientific structure design is reasonable, and when the block selecting oil cylinder was worked, block selecting piston actuated slide block shift fork also drove the block selecting shifting block straight line motion of block selecting piston is converted into the rotation of gearbox shifting axle, finishes the block selecting action; Shift cylinder work is stirred the gearshift shifting block by range piston, drives shifting shaft and moves axially, and realizes gearbox shifting, thereby realizes the shifting of cane type shift device is controlled by hydraulic actuator.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, by specific embodiment.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of new A MT gear shift mechanism comprises block selecting oil cylinder 1, shift cylinder (not shown), block selecting shifting block 6 and gearshift shifting block 8.The piston of block selecting oil cylinder is block selecting piston 2, and the piston of shift cylinder is range piston 9; Be fixedly mounted with slide block shift fork 3 in the bottom of described block selecting piston, between this slide block shift fork, be fixedly mounted with a driving lever 4, this driving lever slip plug-in mounting enters in the made block selecting shift fork 5 of described block selecting shifting block one end, and the made block selecting sliding sleeve 10 of the other end of block selecting shifting block is fixed on the gearbox shifting axle 7 by elastic cylindrical pin 11; At the made gearshift sliding sleeve 12 of an end of the described gearshift shifting block of gearbox shifting axle suit, the other end of gearshift shifting block clamps in the made draw-in groove 13 of the range piston outer wall that connects into described shift cylinder.The gearshift sliding sleeve that the gearshift shifting block is set in shifting shaft partly is flush-mounted in position between the block selecting sliding sleeve that the block selecting shifting block is sleeved on shifting shaft.The gearshift shifting block is shaped with cylindrical projection 14 in the outside vertical that it is shaped with an end of gearshift sliding sleeve, and made groove slip setting-in in this cylindrical projection and the gear box casing prevents its rotation.
Working principle of the present utility model is:
Block selecting oil cylinder and shift cylinder are for being fixedly installed in the external casing.When the block selecting oil cylinder was worked, block selecting piston actuated slide block shift fork also drove the block selecting shifting block straight line motion of block selecting piston is converted into the rotation of gearbox shifting axle, finishes block selecting action (shift gears shifting block this moment under the effect of cylindrical projection, do not rotate); Shift cylinder work, stir the gearshift shifting block by range piston, drive shifting shaft and move axially that (block selecting this moment shifting block moves axially between the slide block shift fork with shifting shaft, the cylindrical projection of gearshift shifting block is slided in gear box casing), realize gearbox shifting, thereby realize the shifting of cane type shift device is controlled by hydraulic actuator.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification all are possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
