Transverse type manual speed variator reverse gear safe device

Abstract

The invention provides a transversely-placed manual transmission backing security device, belonging to the field of automobile transmission technique. The backing security device comprises a selecting and shifting shaft, a security base, a retainer, a pulling block shaft, a torsion spring, a pulling block and an elastic pin; wherein, the security base is sheathed right at the center of the selecting and shifting shaft; the retainer is fixedly arranged on the security base and vertical to the selecting and shifting shaft; the pulling block shaft passes through the elastic pin and is vertically fixed on the security base; the torsion spring enwinds the pulling block shaft; two ends of the torsion spring are respectively fixed on the pulling block. The transversely-placed manual transmission backing security device avoids the backing security pulling block shaft of transmission in the prior art from slipping out when in use, ensures the backing security pulling block to smartly rotate, locks and recovers the gear-backing, simplifies the assembly, eliminates the assembly risks and has easy assembly process.

Description

technical field [0001] The invention relates to a transmission device in the technical field of automobiles, in particular to a reverse safety device for a transverse manual transmission. Background technique [0002] For automobile transmissions, the reverse gear insurance mechanism is an important safety mechanism. When there is a misoperation of directly shifting from the fifth gear to the reverse gear during the driving process of the car, it will cause serious damage to the transmission, cause the power of the car to be interrupted, and affect the safety of driving. The function of the reverse gear safety mechanism is to prevent this kind of misoperation and provide the reverse gear lock function in the process of the car moving forward. [0003] At present, most domestic horizontal manual transmissions use a reverse gear safety mechanism with shift block and block plate structure. This structure is relatively compact and reliable, and the existing transmission also ad...

Problems solved by technology

Such a design requires high assembly requirements. Improper assembly control will cause the risk that the reverse gear safety block will not rotate flexibly and cannot be reset under the action of the torsion spring. In addition, there is a risk that the reverse gear safety shift block shaft will fall out during use, which will cause the reverse gear of the car Defects of insurance failure and no reverse gear
