Problems solved by technology

When the hydraulic retarder is connected to the gearbox, the spline shaft plays the role of connecting the hydraulic retarder to the output shaft of the gearbox, and at the same time, the hydraulic retarder shell is connected to the gearbox end cover through bolts, if When the hydraulic retarder is installed, the position between the retarder housing and the spline shaft is not properly positioned, which will cause the hydraulic retarder to work abnormally, or the rotation resistance is too large to cause serious wear, or even the hydraulic retarder device does not work

Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0023] see figure 1 As shown, the hydraulic retarder installation tool is pressed into the shaft hole of the spline shaft 3 of the hydraulic retarder and pressed to the end face of the speed sensor worm 8 through the bolt 72 to limit the spline shaft 3 to be opposite to the retarder. The positioning flange 4 of the position, the mounting screw 1 that passes through the 4 axis holes of the positioning flange and the 3 axis holes of the spline shaft and is locked on the transmission output shaft 62, is set on the mounting screw 1 and has a boss 54 Penetrate through the light hole of the positioning flange 4 to press the briquetting block 5 on the top of the spline shaft 3, respectively penetrate the light hole of the briquetting block 5 and the screw hole of the positioning flange 4, and tighten the hydraulic retarder spline The spline shaft of the shaft 3 is compo...

Abstract

The invention relates to a tool for installing a hydrodynamic retarder. The tool consists of a positioning flange, an installation screw, a pressing block, a spline shaft pressing bolt and an installation nut, wherein the positioning flange is pressed into a shaft hole of a spline shaft of the hydrodynamic retarder, locked on the hydrodynamic retarder by using a fixed element and used for limiting the relative position of the spline shaft and the retarder; the installation screw passes through the shaft hole of the positioning flange and the shaft hole of the spline shaft and is locked on an output shaft of a speed changing box; the pressing block is sleeved on the installation screw, and a boss of the pressing block passes through a light hole of the flange and is pressed at the top end of the spline shaft; the spline shaft pressing bolt respectively passes through the light hole of the pressing block and a screw hole of the positioning flange and is pressed against the spline shaft of the hydrodynamic retarder; and the installation nut is sleeved on the installation screw and applies an axial pressure to the pressing block. The invention also provides a method for installing thehydrodynamic retarder. By the method, with the installation screw, the installation nut and the spline shaft, a retarder assembly is steadily pressed on the output shaft of the speed changing box; and an installation person can conveniently operate the method.

Description

technical field [0001] The invention relates to a hydraulic retarder installation tool and an installation method thereof. Background technique [0002] As an auxiliary braking device, the hydraulic retarder has been used in large luxury passenger cars. The hydraulic retarder is mainly composed of retarder housing, retarder cover, stator impeller, rotor impeller, spline shaft, controller and other components. When the hydraulic retarder is connected to the gearbox, the spline shaft plays the role of connecting the hydraulic retarder to the output shaft of the gearbox, and at the same time, the hydraulic retarder shell is connected to the gearbox end cover through bolts, if When the hydraulic retarder is installed, the position between the retarder housing and the spline shaft is not properly positioned, which will cause the hydraulic retarder to work abnormally, or the rotation resistance is too large to cause serious wear, or even the hydraulic retarder The device cannot ...
