Abstract
A speed-changing operator is disclosed, belonging to the improvement of automotive operation device. The utility model is aimed to provide a speed-changing operator simplifying a motion mechanism in a speed-changing operator to cause the gear selection and gear shifting operations of a speed-changing operation rod to be simple and convenient. A ball head at the bottom end of the operation rod of the utility model is disposed in a ball bowl; the ball bowl is disposed in the groove of a base and fixed in the groove of the base via a press plate; a gear selection rod is fixedly installed on the operation rod and inserted in the hole of a gear selection arm; one end of the gear selection arm is connected with a transmission gear selection mechanism via a steel rope while the other end is connected to a gear selection shaft via a shaft; the gear selection shaft is inserted on the base; a reset torsion spring is disposed between the gear selection arm on the gear selection shaft and the base; a gear shifting arm is fixedly installed on the operation rod and connected with the transmission gear selection mechanism via a steel rope; an installation guide surface is disposed at the upper end of the ball bowl, an outward-stretching location boss is disposed on the installation guide surface, and an oil guide groove is formed in the ball bowl. The ball head of the speed-changing operation rod of the utility model matches with the ball bowl, and metal elements rub with non-metal elements, with adequate lubrication, small friction force and small gaps. The structure is simple and compact, and the reliability is high.
Description
Technical field
The utility model belongs to the improvement of automobile operation device.
Background technique
In most variable-speed manipulators, shift choosing, gearshift are the cross axle structure now, adopt axle to cooperate with central siphon, and the manufacturing and assembling link are many, the difficult control in frictional force and fit up gap.The driver selects, power and displacement transmission efficiency are low during gear shift operation.
Summary of the invention
The purpose of this utility model is to simplify motion in the variable-speed manipulator, and a kind of easy variable-speed manipulator of choosing, gear shift operation that makes shift is provided.
The bulb of the utility model operating handle bottom places in the ball bowl, the ball bowl places in the groove of base, and be fixed on by pressing plate in the groove of base, be installed with the block selecting bar on the operating handle, the block selecting bar is inserted in the hole of block selecting arm, block selecting arm one end connects speed changer block selecting mechanism by cable wire, the other end axle is connected on the block selecting axle, the block selecting axle is inserted on the base, between block selecting arm on the block selecting axle and base, the return torsion spring is arranged, be installed with gear arm on operating handle, gear arm connects speed changer block selecting mechanism by cable wire; There is the installation guide surface ball bowl upper end, and on the installation guide surface overhanging positioning boss is arranged, and on the ball bowl oil guide slot is arranged.
The utility model is equipped with limiting stopper in the outstanding platform and the gear arm contact position of base plate.
The utility model shift bulb cooperates with the ball bowl, metalwork and non-metal part friction, and fully lubricated, frictional force is little, and the gap is little.Base adopts the die casting aluminum component, for the operation of manipulator shifting provides stable platform.The entire mechanism part is manufactured simple, and is easy to assembly, and the gap is easy to control, raising power and displacement transmission efficiency.The advantage of this new structure is, and is simple and compact for structure, the reliability height.

Fig. 2 is the utility model Fig. 1 left view;
Fig. 3 is the plan view that the utility model Fig. 1 removes operating handle and gear arm;
This is ball bowl structure schematic representation in the model utility variable-speed manipulator for Fig. 4;
Fig. 5 is the plan view of the utility model Fig. 4.
Embodiment
The bulb of the utility model operating handle 1 bottom places in the ball bowl 7, ball bowl 7 places in the groove of base 5, and be fixed on by pressing plate 10 in the groove of base, be installed with block selecting bar 4 on the operating handle 1, block selecting bar 4 is inserted in the hole of block selecting arm 2, block selecting arm 2 one ends connect speed changer block selecting mechanism by cable wire, the other end axle is connected on the block selecting axle 8, block selecting axle 8 is inserted on the base 5,5 of block selecting arm 2 on block selecting axle 8 and bases have return torsion spring 9, be installed with gear arm 3 on operating handle 1, gear arm 3 connects speed changer block selecting mechanism by cable wire; There is the guide surface 11 of installation ball bowl 7 upper ends, and on the installation guide surface 11 overhanging positioning boss 13 are arranged, and oil guide slot 12 is arranged on ball bowl 7.
The utility model is equipped with limiting stopper 6 in the outstanding platform and gear arm 3 contact position of base plate 5.
The variable-speed manipulator base is fixed on the body platform, for manipulator provides working platform.During the block selecting operation, operating handle swings in Fig. 1 left view, and the operating handle bulb rotates in the ball bowl, drives the block selecting bar and moves up and down, thereby the block selecting arm is rotated around the block selecting axle, realizes the block selecting action.After operating handle carries out block selecting action and departs from initial position, unclamp operating handle, operating handle can be got back to initial position under the effect of return torsion spring.During shift control, operating handle swings in Fig. 1 plan view, and the operating handle bulb rotates in the ball bowl, drives gear arm and moves up and down, thereby realize the gearshift action.When operating handle was swung left, when arriving several angle, gear arm can be run into limiting stopper, avoids gear arm and base to collide, and plays spacing and buffer function.
Among Fig. 2, speed change is handled cone match between ball bowl and the base, locatees with positioning boss.The operating handle bulb is assemblied in the ball bowl along guide surface is installed, and forecourt bowl inner ball surface and operating handle bulb is installed all is coated with moderate lubrication fat.Operating handle selects, in the gear shift operation process, ball bowl inner ball surface rubs mutually with the bulb outer spherical surface, lubricating grease is moving along oil guide slot and ball bowl sphere bottom string, makes two relative movement obtain sufficient lubrication everywhere, thereby raising power and displacement transmission efficiency.
