Reverse gear swing arm support assembly

Abstract

The invention discloses a reverse gear swing arm support assembly. Swing arms (1) are in U shapes, the closed ends of the two swing arms (1) are connected through a connecting plate (2), the middles of the upper lateral side and the lower lateral side of the connecting plate (2) are provided with shifting fork claws (4), the shifting fork claws (4) and the swing arms (1) are located on the same side of the connecting plate (2), a back plate (3) is arranged at the back of the connecting plate (2) in the mode of being vertically perpendicular to the connecting plate (2), a central spindle (5) is fixedly sleeved with the back plate (3), the central spindle (5) is further and movably sleeved with a support (6), the support (6) comprises a vertical plate (6a) and a transverse plate (6b), the central spindle (5) is movably sleeved with the vertical plate (6a), the transverse plate (6b) is connected to the lower end of the vertical plate (6a), the transverse plate (6b) and the back plate (3) are located on the two sides of the vertical plate (6a) respectively, and a bolt hole (11) is formed in the transverse plate (6b). According to the reverse gear swing arm support assembly, the reverse gear swing arms of novel structures are adopted, meanwhile, the pre-tightening force is provided by a compressed spring, the displacement accuracy of a reverse-gear gear is effectively improved, and meanwhile the reverse gear swing arm support assembly has the advantages of being convenient to reset, firm in installation, low in manufacturing cost and the like.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a reverse gear swing arm bracket assembly in an automobile gearbox. Background technique [0002] The reverse gear is the gear that realizes the reverse function of the car. The reverse gear swing arm is driven to swing through the reverse gear shift fork in the gearbox, so that the reverse gear is meshed with the output gear synchronizer and the input shaft at the same time. At this time, the output gear is The looper is on the synchronizer, and the power is transmitted from the input shaft to the reverse gear, and then to the output shaft to achieve the purpose of reverse gear. The reverse gear swing arm adopted on the market is usually a strip plate hinged on the reverse gear swing arm support, and the swing of the reverse gear swing arm is driven by the movement of the reverse gear shift fork. The displacement of the reverse gear swing arm of this structure is not accurate enough ...

AI Technical Summary

Problems solved by technology

The displacement of the reverse gear swing arm with this structure is not accurate enough when the reverse gear is shifted. At the same time, because the reverse gear swing arm swings without preload, it is easy to cause insufficient swing and rebound.
