At present, sheet metal punching welding type torque converters at home and abroad are all of an integral welding type structure, and due to the limitation of the integral welding type structure, the torque converters can only be installed on a core shaft and a guide wheel seat in a floating mode through splines (namely, the torque converters can move back and forth relative to the guide wheel seat and the core shaft during working, and see figure 4).

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a panel beating dashes and welds formula hydraulic torque converter with fixed torque conversion core structure.

A sheet metal punching welding type hydraulic torque converter with a fixed torque conversion core structure comprises a torque conversion core 1, an input guide seat 3, a core shaft 10, a guide wheel seat 7 and a shell 14; the torque-converting core 1 is sleeved on the mandrel 10 in a spline fit manner, the input guide seat 3 is fixedly connected with one end of the torque-converting core 1 and is coaxial with the mandrel 10, and the guide wheel seat 7 is positioned at the other end of the torque-converting core 1;

the improvement lies in that: a retainer ring 4 is arranged at the end part of the mandrel 10 corresponding to the input guide seat 3;

a pair of bearing retainer rings 11 and a bearing 12 are sequentially arranged at the end part of the mandrel 10 corresponding to the guide wheel seat 7, the bearing 12 is fixedly arranged on the mandrel 10 between the pair of bearing retainer rings 11, a hole retainer ring 13 is arranged at the axial outer side of the bearing 12,

fixing the torque-converting core 1 on the core shaft 10;

the end part of the mandrel 10 corresponding to the guide wheel seat 7 is provided with a connecting hole, and torque is transmitted to the gearbox through a spline.

The technical scheme for further limiting is as follows:

the circumference of the input guide seat 3 is fixedly connected with the axial end part of the torque converting core 1 through a threaded connecting piece, and a sealing ring 2 is arranged between the circumference of the input guide seat 3 and the axial end part of the torque converting core 1.

The sealing ring 2 is an oil-resistant heat-resistant rubber sealing ring.

The bearing 12 is a deep groove ball bearing.

The beneficial technical effects of the utility model are embodied in the following aspects:

1. the torque converter cannot transmit axial force to an engine flywheel during working under the action of the retaining ring of the mandrel, so that the sheet metal stamping type torque converter is ensured not to apply axial force to the flywheel end of the engine, the engine fault caused by the unilateral abrasion of an engine thrust bearing is avoided, and the reliability of the connection of the sheet metal stamping type torque converter and the engine is improved; the working reliability of the engine is improved;

2. the utility model discloses a dabber other end is fixed on the bearing owing to use the retaining ring for the shaft, and the bearing is fixed on the torque converter shell through the retaining ring for the hole again, consequently effectually prevented that the displacement drunkenness around traditional panel beating punching press formula torque converter is frequent on dabber and guide pulley seat, has effectively avoided the spline abnormal wear of transmission moment of torsion, improves the reliability of torque converter life and gearbox, reduces cost of maintenance.

Detailed Description

Examples

The present invention will be further described with reference to the accompanying drawings by way of examples.

Referring to fig. 1, a sheet metal punching welding type torque converter with a fixed torque conversion core structure comprises a torque conversion core 1, an input guide seat 3, a mandrel 10, a guide wheel seat 7 and a shell 14. The torque-converting core 1 is sleeved on the core shaft 10 in a spline fit manner, and the input guide seat 3 is fixedly connected with one end of the torque-converting core 1 and is coaxial with the core shaft 10; the guide wheel seat 7 is positioned at the other end of the torque conversion core 1;

referring to fig. 2, a retainer ring 4 is fixedly mounted at the end of the mandrel 10 corresponding to the input guide seat 3 to prevent the torque converting core 1 from moving to one side of the input guide seat 3;

referring to fig. 3, a pair of bearing retainer rings 11 and a hole bearing 13 are sequentially arranged at the end of the mandrel 10 corresponding to the guide wheel seat 7, a bearing 12 is fixedly installed on the mandrel 10 between the pair of bearing retainer rings 11, and the bearing 12 is a deep groove ball bearing. A hole retainer 13 is mounted axially outward of the bearing 12.

Because the torque conversion core 1 can not transmit axial force to the engine flywheel under the action of the shaft retainer ring 4 of the mandrel 10 during working, the reliability of the engine is improved. The other end of the mandrel 10 is fixed on a bearing 12 by using a limiting retainer ring 11, and the bearing 12 is fixed on a shell 14 by using a hole retainer ring 13, so that the front and back displacement play of the traditional sheet metal stamping type torque converter core on the mandrel 10 and the guide wheel seat 7 is effectively prevented, the failure of a connecting spline caused by abrasion is avoided, and the reliability and the service life of the torque converter and the guide wheel seat are improved.
