Abstract
The utility model relates to a self-lock spring assembly for a transmission of a light-weight vehicle. The self-lock spring assembly comprises a self-lock spring, a self-lock spring casing, a steel ball and a steel ball seat, and is characterized in that the self-lock spring is mounted in the self-lock spring casing; the steel ball seat and the steel ball are arranged on the self-lock spring in sequence; and external threads are formed on the self-lock spring casing. The self-lock spring, the self-lock spring casing and the steel ball are integrated together, and the steel ball is clung to a closed end at the bottom of the self-lock spring casing under the action of the force of the self-lock spring. When the self-lock spring assembly is used, the casting quality of the inner wall of the self-lock spring casing in the mounting position is not required to consider, and only the mounting surface is required to be processed.
Description
Technical field
The utility model relates to a kind of Light-duty Vehicle speed changer self-locking spring assembly, belongs to auto manufacturing.
Background technique
In some cases, such as having adopted the shift fork that on fork shaft, slides in the speed changer, the slip shift fork the self-locking groove (V-type groove) of corresponding gear need directly on this shift fork, to process, and corresponding self-locking mechanism is installed on the case of transmission, owing to be difficult to the castability of control self-locking groove inner walls and the appropriate clearance between inner walls and the groove, be not easy to again inner walls is processed, so traditional self-locking form (directly self-locking spring, steel ball being contained in the hole on the housing) is difficult to realize.Traditional self-locking form generally be on case of transmission directly processing portal, then steel ball, spring be contained in Kong Lizai with plug screw or loam cake spring compression, this structure often is subjected to the restriction of speed changer structure, and can't realize, and is not easy to assembling and maintenance.
Summary of the invention
The purpose of this utility model is to provide a kind of Light-duty Vehicle speed changer self-locking spring assembly, and it is an a kind of modular self-locking spring mechanism, does not need to consider the castability of installed position inner walls during use, only needs the installation and processing face.
The technical solution of the utility model is achieved in that Light-duty Vehicle speed changer self-locking spring assembly, is made up of self-locking spring, self-locking spring shell, steel ball and steel ball seat; It is characterized in that: self-locking spring is installed in the self-locking spring shell, is furnished with steel ball seat and steel ball on the self-locking spring successively; On the self-locking spring shell, attacked outside thread.
Good effect of the present utility model is that spring, shell and steel ball are integrated, and steel ball has been attacked outside thread abutting against under the effect of self-locking spring power in the closing in of outer casing bottom on shell.Do not need to consider the castability of installed position inner walls during use, only need the installation and processing face.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1, Light-duty Vehicle speed changer self-locking spring assembly is made up of self-locking spring 3, self-locking spring shell 4, steel ball 1 and steel ball seat 2; It is characterized in that: self-locking spring 3 is installed in the self-locking spring shell 4, is furnished with steel ball seat 2 and steel ball 1 on the self-locking spring 3 successively; On the self-locking spring shell, attacked outside thread.
Under the original state, self-locking spring 3 is in compressive state, and the spring force that acts on the steel ball seat 2 compresses the steel ball 1 and closing in place of self-locking spring shell 4, and steel ball 1 can't be deviate from.Self-locking spring shell 4 is installed on the case of transmission and the corresponding position of self-locking groove by screw thread, thereby steel ball 1 and self-locking groove are interacted.Steel ball 1 need overcome spring force and cross groove, realizes auto-lock function.
