Problems solved by technology

[0002] Automobile tailgate electric strut is a common auto accessory. The common tailgate electric strut realizes the retractable operation by driving the motor to drive the screw to rotate. There are different levels of electric struts in the assembly process of the customer's production line or in the later use of the user. The possibility of abusive operation or violent operation will lead to overload of the drive motor, which will cause different degrees of damage to the planetary gear of the reducer during overload operation, thus affecting the subsequent normal use of the electric strut

Abstract

The invention relates to the technical field of automobile accessories, in particular to a bidirectional clutch which is used for overload clutch between a driving motor and a lead screw of an automobile electric supporting rod and comprises a sleeve, a rotor and clutch assemblies, wherein the sleeve is connected with an external lead screw assembly; the rotor is arranged in the sleeve and connected with an external driving motor, a plurality of groove groups are arranged on the outer surface of the rotor, and an outer contact surface is formed between every two adjacent groove groups; and the corresponding clutch assemblies are uniformly arranged in each groove group, and the clutch assemblies are used for achieving the overload clutch between the rotor and the sleeve. The invention further provides a clutch system, which comprises the lead screw assembly, the driving motor and the bidirectional clutch. According to the bidirectional clutch and the clutch system provided by the invention, the rotor and the sleeve are matched with each other, and transmission separation between the rotor and the sleeve is realized by utilizing the clutch assemblies during overload, so that a reduction gearbox gear of the driving motor is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a two-way clutch and a clutch system. Background technique [0002] Automobile tailgate electric strut is a common auto accessory. The common tailgate electric strut realizes the retractable operation by driving the motor to drive the screw to rotate. There are different levels of electric struts in the assembly process of the customer's production line or in the later use of the user. The possibility of abusive operation or violent operation will lead to overload of the drive motor, which will cause different degrees of damage to the planetary gear of the reducer during overload operation, thus affecting the subsequent normal use of the electric strut. In view of this, we propose a two-way clutch and clutch system. Contents of the invention [0003] The object of the present invention is to provide a two-way clutch and a clutch system to solve the problems raised in the ba...
