Gear reversing and shifting mechanism of rear-drive manual transmission

Abstract

The invention discloses a gear reversing and shifting mechanism of rear-drive manual transmission which can prevent gear chaos and gear disconnection. A longitudinal limit slot (13) which inclines towards one side is disposed at a position, close to a shifting fork (11), on the connecting surface (12) of a gear reversing and shifting fork (10). A matching longitudinal limit slot (43) matched with the longitudinal limit slot (13) is formed in the left side of the connecting surface (42) of a gear reversing shifting fork support (40). The right side of the connecting surface of the gear reversing and shifting fork is rotatably connected with the right of the connecting surface of the gear reversing shifting fork support. A gear reversing shifting fork limit part (30) is located between the longitudinal limit slot and the matching longitudinal limit slot, the front end and the rear end of the gear reversing shifting fork limit part respectively extend out of the longitudinal limit slot and the matching longitudinal limit slot, and the rear end is connected with a gear shifting fork. Two ends of a return elastic part (20) are respectively connected to the top outer edge located on the outer side of the longitudinal limit slot and the front side outer edge of a pressing plate.

Description

Technical field [0001] The invention relates to an automobile transmission, in particular to a reverse gear shifting mechanism of a rear-drive manual transmission. Background technique [0002] See Image 6 , Figure 7 , Figure 8 with Picture 9 , An existing reverse gear shifting mechanism of a rear-drive manual transmission includes a reverse gear shift fork 10, a return elastic member 20, a reverse gear limiter 30, and a reverse gear fork bracket 40. The elastic member 20 is a return spring. The reverse gear shift fork 10 includes a connecting surface 12 and a shift fork 11 integral with the connecting surface 12 and extending outward from one side of the connecting surface 12; the reverse gear shift fork bracket 40 includes a transmission box body The upper mounting surface 41 and the connecting surface 42 connected to one end of the mounting surface 41 and extending upward: a groove hole 13 is provided on the connecting surface 12 of the reverse shift shift fork 10 near the...

Problems solved by technology

There are two problems in the reverse gear shifting mechanism of this rear-drive manual transmission, one: when the transmission is transported, if there is enough vibration, the reverse gear shift fork 10 will rotate counterclockwise to overcome the spring force to reverse gear Second, when reversing on bad road conditions, if there is enough vibration, the reverse gear shift fork 10 will rotate clockwise to overcome the spring force and the reverse gear will be withdrawn, causing the reverse gear to be disengaged.
