Abstract
The utility model provides a special dismounting tool for an oil seal for an automatic transmission, belonging to the technology field of special tools for vehicles, and exactly relates to a special tool for dismounting an oil seal for a Toyota A540 automatic transmission. The special dismounting tool is formed by a dismounting bolt, a tensioning arm, a spring, and a central part, and pins. The dismounting bolt and the central part are connected via trapezoidal screw threads, axial force provided via screw drive is used to dismount the oil seal from the automatic transmission. The lower end of the dismounting bolt is provided with a cylindrical boss, a cylindrical hole is machined at the right side of the tensioning arm, the spring is installed in the cylindrical hole, and one end of the spring compresses the pin at the side via spring force. The special dismounting tool in the utility model can realize nondestructive dismounting of the oil seal of the Toyota A540 automatic transmission, is provided with characteristics of simple structure, convenient operation, reliable safety, low cost, etc., and is also suitable for dismounting of oil seals of automatic transmissions in the same kind.
Description
Technical field
The utility model belongs to and relates to the automobile technical field of tools, a kind of specific purpose tool that is used to dismantle the A540 of Toyota automatic transmission oil sealing of definitely saying so.
Background technology
In recent years, the recoverable amount of China's automobile increases sharply, and meanwhile, Toyota Motor also is steady-state growth situation in the recoverable amount of China.The automatic transmission that Toyota Motor adopts AW company to produce usually, wherein the use amount of A540 automatic transmission is bigger.Oil sealing is the important potted component of A540 automatic transmission, and assembly precision is high.Simultaneously, adopt the interference fit assembling between oil sealing and the oil pump, have very big axial force between the two, the dismounting oil sealing must overcome the effect of axial force, and the nondestructive demounting difficulty is big.At present, during the dismounting A540 of Toyota of Auto repair shop automatic transmission oil sealing, generally use general oil seal remover, indivedual repair shops even use screwdriver and hammer are dismantled.Because the general utility tool specific aim is not strong, inconvenient operation, easy damaged oil sealing during dismounting can't guarantee its original assembly precision when causing oil sealing to be reinstalled, stay potential safety hazard easily.The utility model is applicable to the dismounting of the A540 of Toyota automatic transmission oil sealing, can effectively overcome the axial force between oil sealing and the oil pump, and does not damage the oil sealing surface, do not destroy the quality of fit between oil sealing and the oil pump.Have simple in structure, easy to operate, safe and reliable and characteristics such as cost is low.
Summary of the invention
The purpose of the utility model is to provide a kind of specific purpose tool of dismantling the A540 of Toyota automatic transmission oil sealing.The utility model is made up of demounting bolt, tensioner arm, spring, central module and pin.It can use less moment of torsion to obtain bigger axial force, and be characterized in: the lower end of demounting bolt has cylindrical boss; The tensioner arm right side is processed with a cylindrical hole, and spring is installed in the circular hole, and an end of spring uses spring force to compress the pin of this side.Demounting bolt is a screw rod, uses the mode of turning clockwise can make its decline, and use is rotated counterclockwise mode can make its rising.Demounting bolt and central module come transferring power through worm drive.The screw thread of demounting bolt and central module all adopts trapezoidal thread.The turn clockwise hexagon nut at demounting bolt top makes demounting bolt move downward the axle head that is pressed in oil pump shaft until the cylindrical boss of demounting bolt lower end.Use spanner to continue the rotation demounting bolt, the axial force that worm drive provide can be removed oil sealing from automatic transmission.Two pin branches are listed in the two ends of central module, and fixing with central module through pin is connected.In two pins one fixes with tensioner arm through pin and is connected, another then be installed in tensioner arm in spring in the circular hole freely be connected.Pin keeps opening attitude under the effect of spring force, and then under external force, two pins close up, and can insert in the oil sealing easily during work.During the dismounting oil sealing, spring can provide a tensile force to oil sealing through pin, when guaranteeing the dismounting oil sealing, can not come off with specific purpose tool.The bottom of 2 pins all is designed with platform, and platform contacts with fluid side during dismounting, makes oil sealing stressed even in unloading process, has protected oil sealing body and mounting plane.The utility model can be realized the nondestructive demounting of the A540 of Toyota automatic transmission oil sealing.This specific purpose tool is simple in structure, and installation and easy to operate, respond well is suitable for the dismounting of similar automatic transmission oil sealing.
Description of drawings
Fig. 1 is the automatic transmission oil sealing removal tool special structure chart of the utility model.
Fig. 2 is the work sketch map of the utility model.
Each numeral as shown in the figure is represented respectively as follows: 1. demounting bolt; 2. tensioner arm; 3. spring; 4. central module; 5. pin.
The specific embodiment
During work, dismantle the oil sealing of the A540 of Toyota automatic transmission according to following steps: (1) counterclockwise rotates demounting bolt 1, and it is moved upward, and avoids when pin stretches into oil sealing, running into oil pump shaft.(2) inwardly push pin 5 bottoms,, two pins is stretched into oil sealing inside when pin-pitch during less than the oil sealing diameter.(3) unclamp pin, two pins outwards opens under spring 3 effects.Because two pins is inboard at oil sealing, will and compress with side contacts in the oil sealing after pin opens fully.There is platform pin 5 lower ends, and platform is close to the oil sealing surface, and both can not separate under the effect of spring force.(4) clockwise direction rotation demounting bolt 1, the boss up to demounting bolt 1 lower end stops when being pressed on the oil pump shaft.(5) use the spanner clockwise direction to rotate the nut at demounting bolt 1 top, make it to continue to move downward.(6) after oil sealing and oil pump disengage, take off oil sealing, demounting bolt 1 is resetted.Demounting bolt 1 adopts hexagon-headed bolt, and screw thread is Tr60 * 7-7e, and material is 45 steel, and the bottom is a cylindrical boss, is of a size of Ф 50 * 15mm.The model of spring 3 is Tr1750, and material is spring steel (SUP).Two pins 5 and central module 4 are for pin is connected, and wherein 1 pin also adopts pin to be connected with tensioner arm 2, uses 3 taper bolts altogether, and model is pin GB/T 117 8 * 60.Tensioner arm 2, central module 4 and pin 5 adopt customized, and material uses 45 steel.Central module 4 adopts bolt to be connected with demounting bolt 1, and the height of central module is more than 70mm reaches.
Claims (1)
1. automatic transmission oil sealing removal tool special; It comprises demounting bolt (1), tensioner arm (2), spring (3), central module (4) and pin (5); It is characterized in that: there is a cylindrical hole on the tensioner arm right side; Spring is installed in this circular hole, and an end of spring uses spring force to compress the pin of this side.
