Description
Technical field
The present invention relates to the automotive transmission operating mechanism, more specifically, relate to the self-locking device of automotive transmission operating mechanism.
Background technique
The effect of automotive transmission operating mechanism is the driving conditions according to automobile; The driver can pass through joystick at any time, drives selector fork axle, shifting block and shift fork and moves, and certain gear is changed or taken to speed changer; To realize the elemental motion of block selecting and gearshift, realize the function of speed change.
For guarantee speed changer under any circumstance can both be accurately, safety, work reliably, transmission control is provided with safety installations, comprising:
(1) self-locking device, this self-locking device is made up of self-locking steel ball and self-locking spring, and its effect is to guarantee that gearshift puts in place, prevents automatic off-gear.
(2) interlock, this interlock is made up of interlocking plunger and interlocking steel ball, and its effect is to prevent to hang simultaneously into two retainings.
(3) lock that reverses gear, this lock that reverses gear is made up of with the lock spring that reverses gear the lock pin that reverses gear, and its effect is to prevent that the mistake extension from reversing gear.
As shown in Figure 1; The self-locking device of most transmission controls all comprises housing 1 (this housing 1 is the part of case of transmission 1), selector fork axle 2, self-locking spring 4 and self-locking steel ball 5; Said housing 1 has cavity 9; Said self-locking spring 4 is contained in the said cavity 9, has a plurality of grooves 10 on the said selector fork axle 2, and said self-locking steel ball 5 is force-fitted in the said groove 10 through said self-locking spring 4.The upper surface of every selector fork axle 2 is distributed with three grooves 10 usually vertically, when any selector fork axle 2 axially moves to the position of neutral or a certain work gear together with selector fork 3, must have a groove 10 just in time to aim at self-locking steel ball 5.So self-locking steel ball 5 embeds in this groove 10 under the pressure effect of self-locking spring 4; The axial position of selector fork axle 2 promptly is fixed; Thereby selector fork 3 also is fixed on neutral or a certain work gear together with sliding gear (or clutch collar), can not deviate from voluntarily.During gearshift, the driver applies certain axial force to gearshift declutch shift shaft 2, and the pressure that overcomes self-locking spring 4 pushes back in the hole extruding in the groove 10 of self-locking steel ball 5 by selector fork axle 2, and selector fork axle 2 can move axially again.
In traditional self-locking device, self-locking spring 4 is contained in the long and narrow cavity 9 of case of transmission 1 with self-locking steel ball 5, directly contacts with case of transmission 1, and simultaneously, self-locking spring 4 also is directly to contact with self-locking steel ball 5 under self-locking spring 4 pressure effects.When carrying out gear shift operation; Axial motions take place in selector fork axle 2, make between self-locking steel ball 5 and self-locking spring 4 and the housing 1 and they self between relative movement takes place, thereby the generation sliding friction; And frictional force is bigger; Parts are prone to take place wearing and tearing and damage, and influence the feel and the travelling comfort of driver's gearshift, and gear shift operation is had a negative impact.
Summary of the invention
Technical problem to be solved by this invention is when carrying out gear shift operation; Self-locking steel ball, self-locking spring and housing produce bigger force of sliding friction each other; Make parts be prone to take place wearing and tearing and damage, and influence the feel and the travelling comfort of driver's gearshift, gear shift operation is had a negative impact.
For solving the problems of the technologies described above, the present invention provides a kind of self-locking device of transmission control, and this self-locking device comprises housing, selector fork axle, self-locking spring and self-locking steel ball; Said housing has cavity, and said self-locking spring is contained in the said cavity, has a plurality of grooves on the said selector fork axle; Said self-locking steel ball is force-fitted in the said groove through said self-locking spring; Wherein, said self-locking device also comprises spring bracket and the bearing that is positioned at said cavity, and said self-locking spring is positioned at the top of said spring bracket; Said self-locking steel ball is positioned at the bottom of said spring bracket, and said bearing is between said spring bracket and said housing.
Through technique scheme of the present invention, change the sliding friction each other of self-locking steel ball, self-locking spring and housing into rolling friction, thereby reduced frictional force, protect the parts of self-locking device, and improved the feel and the travelling comfort of gearshift.
Other features and advantages of the present invention will partly specify in embodiment subsequently.
