Abstract
The utility model pertains to the auto manufacture, in particular to an auto the transmission box reverse shaft locking device, which comprises a reverse shaft, transmission box casing and an accessory transmission box body, and is characterized in that a radial locking steel ball is provided between the reverse shaft and the transmission box casing; the reverse shaft end face and the box body of the accessory the transmission box is closed to realize the radial locking. In the utility model the reverse shaft directly uses the steel ball and the transmission box casing to realize the radial locking and realize the coaxial locking with the box body of the accessory the transmission box, thereby simplifying the processing technology for the reverse shaft, shortening the reverse shaft, saving the raw material, reducing the locking splints of the original structure, the spring splints and the hexagon bolt, simplifying the reverse shaft assembly and maintenance technology and the processing technology for the box body of the accessory the transmission box, and improving the working efficiency.
Description
Technical field
The utility model belongs to the automobile making class, specifically is a kind of automotive transmission reverse gear shaft Locking Device.
Background technique
At present, when the auxiliary transmission of domestic and international employed compact car speed changer is worked, the reverse gear transition gear does not bear the effect of axial force, and reverse gear transition gear sky is enclosed within on the reverse gear shaft, the load that reverse gear shaft bore is mainly radial load, thrust load and the torque that is born are less, now often adopt reverse gear locking plate and bolt to realize the locking of reverse gear shaft, though this structure can play the locking effect, but its reverse gear shaft processing technology complexity, cost of production is higher, the assembling of reverse gear shaft assembly, the maintenance process complexity has brought very burden also for simultaneously the processing of auxiliary transmission housing.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of and makes simply, uses automotive transmission reverse gear shaft Locking Device reliable, easy to maintenance, good economy performance.
The technical solution of the utility model is as follows:
A kind of automotive transmission reverse gear shaft Locking Device comprises reverse gear shaft, case of transmission, auxiliary transmission casing, it is characterized in that: radially locking steel ball is arranged between reverse gear shaft and case of transmission, and reverse gear shaft end face and auxiliary transmission casing are near to realize axial locking.
The utility model reverse gear shaft is directly with realizing radially locking between steel ball and case of transmission, and with the auxiliary transmission casing near, realize axial locking by auxiliary transmission casing end face, thereby simplified the processing technology of reverse gear shaft, and reverse gear shaft has been shortened, saved raw material, reduced the part such as locking plate, compression spring, hex head bolt of original structure, simplify assembling, the maintenance process of reverse gear shaft, simplified the processing technology of auxiliary transmission casing, improved working efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
