Detailed description of the invention
Describe the present invention in detail below in conjunction with specific embodiments and the drawings.
Embodiment 1:
As shown in Figure 1, 2, the gearshift of the present embodiment comprises base 1 and is installed on gear support 2, shift selection arm 3, the joystick 4 on base 1, joystick 4 is connected to control gear with shift selection arm 3, a pad 5 is installed on joystick 4, the internal diameter of pad 5 is less than the diameter of joystick 4 bodies of rod of pad below, is processed with the screw thread that diameter is greater than pad internal diameter and is less than pad external diameter on the joystick body of rod of pad 5 tops; On joystick 4, by screw thread fit, a handle assembly 6 is installed, the end face of the bottom of handle assembly 6 and pad 5 offsets.
The manufacture method of above-mentioned gearshift comprises the steps:
A: by joystick 4 bodies of rod utilize lathe vertically car fall the part on body of rod top, the diameter on body of rod top is diminished, thereby it is step-like that the body of rod is formed, and pad 5 is inserted in to joystick 4 bodies of rod and is supported on step, the internal diameter of described pad 5 is less than the diameter of joystick 4 bodies of rod of pad below;
B: flat dies is placed on to joystick 4 tops, with the fixing joystick 4 of fixture, rubs the screw thread that diameter is greater than pad 5 internal diameters with flat dies on joystick 4 bodies of rod;
