Abstract
The invention discloses a clutch control device with an axial buffer function, which comprises a fixed seat sleeve, a shifting fork and a separation bearing assembly. The separation bearing assembly is sleeved on the fixed seat sleeve; one end of the shifting fork is connected with the separation bearing assembly and the other end is connected with a pedal in a driving cab; an axial damper is arranged on the fixed seat sleeve, is connected with the separation bearing assembly and consists of a cylinder and a piston rod; the cylinder is arranged on the fixed seat sleeve; the piston rod is arranged on the separation bearing assembly; and an air vent is arranged on the wall of a chamber formed by the cylinder and the piston rod. By adopting the technical scheme, under the action of the axial damper, axial impact on a clutch can be eliminated effectively so as to enable the clutch engaging to be gentle, and a transmission gear can be prevented from being damaged by impact during gear shifting.
Description
Technical field:
The present invention relates to a kind of clutch control device.
Background technique:
Car (ship) is fixed on clutch assembly on the back plane of flywheel with screw with in the flywheel casing of clutch between motor and gearbox, and the output shaft of clutch is connected with the input shaft of gearbox.Clutch is mainly realized guaranteeing the automobile balance starting, is convenient to gear shift, is prevented power train overload three big functions.What extensively adopt on automobile at present is the friction clutch of using spring compression.In automobile (ship) running process, the torque that motor sends passes to speed changer by flywheel-friction disk-platen-clutch output shaft.The driver can step on or release the clutch pedal as required, transmission by parts, make diaphragm spring drive the platen reach or after move, thereby control flywheel, friction disk and platen temporary transient separate and engage gradually, to cut off or to transmit the power of motor to the speed changer input.
Traditional vehicle (ship) has designed damping spring with friction-disc clutch on the circumference of clutch disk, step on the moment of unclamping clutch pedal after the clutch pedal gearshift the driver, realizes that flywheel-friction disk-generation circumferentially cushioned when the platen three engaged.But when above-mentioned three engages, except producing circumferential impact, also can produce axial impact, and above-mentioned traditional structure only solves circumferential buffering.And because the existence of axial impact, vehicle is in starting or in travelling during gear shift operation, will make vehicle preshoot, pause and transition in rhythm or melody or flame-out if release the clutch pedal is too fast, not only greatly influence the travelling comfort of vehicle drive personnel and passenger, and influenced the working life of gearbox gear owing to this impact.
Summary of the invention:
The objective of the invention is provides a kind of clutch control device that has axial buffer function in order to overcome the shortcoming of above-mentioned prior art.
For achieving the above object, technological scheme provided by the invention is: the clutch control device that has axial buffer function, include fixed seating, fork and release bearing assembly, release bearing assembly is set on the fixed seating, fork one end is connected with release bearing assembly, the other end is connected with the operator cabin pedal, is provided with axial damper on fixed seating, and axially damper is connected with release bearing assembly.
Described damper is made of cylinder body and piston rod, and cylinder body is located on the fixed seating, and piston rod is located on the release bearing assembly, and the chamber wall body that surrounds in cylinder body and piston rod is provided with vent.
After adopting technique scheme, under the effect of axial damper, can effectively solve the axial impact that clutch is received, make clutch soft, damage gearbox gear because of impact when avoiding shifting gears.

Fig. 1 is the structural representation that clutch control device piston rod of the present invention is pressed to the cylinder body state;
Fig. 2 is the structural representation that clutch control device piston rod of the present invention detaches the cylinder body state;
Fig. 3 is the three-dimensional exploded view of clutch control device of the present invention.
Embodiment:
Now elaborate the present invention in conjunction with the accompanying drawings:
The clutch control device of present embodiment includes fixed seating 1, the release bearing assembly 3 of fork 2 and roof pressure clutch diaphragm spring, fixed seating 1 is fixedly mounted on the gear box casing, one end of fork 2 is connected with release bearing 31, the other end is connected with the operator cabin pedal, the input shaft of gearbox passes fixed seating 1 successively, fork prong 21 and release bearing 31, be connected with the rotation central axis of clutch again, between release bearing assembly 3 and fixed seating 1, be connected with axial damper 4, this damper 4 is made of cylinder body 41 and piston rod 42, cylinder body 41 is located on the fixed seating 1, piston rod 42 is located on the release bearing assembly 3, and sidewall is provided with vent 5 in the bottom of cylinder body 41.
Above-mentioned vent 5 is except the bottom sidewall of being located at cylinder body 41, and it can also be arranged on cylinder body 41 bottoms, also can be arranged on the piston rod 42, can realize the object of the invention.
The above only is preferred embodiment of the present invention, is not the present invention is done any pro forma restriction.Any those of ordinary skill in the art, do not breaking away under the technical solution of the present invention scope situation, all can utilize the method and the technology contents of above-mentioned announcement that technical solution of the present invention is made many possible changes and modification, or be revised as the equivalent embodiment of equivalent variations.So every content that does not break away from technical solution of the present invention, the equivalence of doing according to the present invention's shape, structure and principle changes, and all should be covered by in protection scope of the present invention.
