Two-way overrun clutch relay device

Abstract

The invention discloses a two-way overrun clutch relay device. The two-way overrun clutch relay device is used for the transmission of an MPV sliding door. The two-way overrun clutch relay device comprises a driving shaft, and a star wheel, a middle ring, an outer ring, a gear and a rack are arranged on the driving shaft sequentially from inside to outside. The star wheel includes a star wheel disc and a star wheel shaft, the middle ring includes a middle ring disc and a middle ring shaft, the star wheel is arranged on the drive shaft in a sleeving mode, the middle ring is arranged on the starwheel shaft in a sleeving mode, the outer ring is arranged on the middle ring shaft in a sleeving mode, the gear is arranged on the outer ring in a sleeving mode, and the gear and rack are directly engaged for transmission. The middle ring shaft is uniformly provided with gaps, and the gaps are provided with rollers, the star wheel acts on the outer ring through the rollers. The two-way overrun clutch relay device uses friction force generated in a space formed by the star wheel, the middle ring and the outer ring under the dynamic change to realize automatic overrun and joint effects, solvesthe problem that a rack and pinion transmission system can only be driven by a single motor and the collision and interference caused by the unsynchronization of double drive, and ensures synchronousoperation and mutual noninterference of mechanical power and motor power input and smooth operation of relay process.

Description

technical field [0001] The invention relates to the field of double-drive relays, in particular to a two-way overrunning clutch relay device. Background technique [0002] With the development of science and technology, the sliding door of MPV has realized the transformation from the mechanical drive of the door handle to the motor drive. When there is a mechanical force on the door handle due to manual push and pull, the sliding door at this time is subject to two driving forces, which will cause motion interference and cause damage to the motor and transmission. In order to realize the non-interference between the motor drive and the human-mechanical drive and the smooth progress of the relay process, higher requirements are put forward for the transmission relay device. Contents of the invention [0003] The object of the present invention is to provide a two-way overrunning clutch relay device in order to overcome the above problems. [0004] In order to achieve the ...
