Background

Along with the improvement of living standard, people also put forward higher requirement to the quality of car, and current electronic gear shifter is mainly the pin formula, and its mode of operation is close with traditional mechanical type selector, therefore is becoming difficult to satisfy all users 'user demand in the aspect of travelling comfort, manipulation sense etc. on the basis, knob formula selector has gradually obtained consumer's favor because its mode of shifting is novel, technological sense is strong.

At present, knob selector provides the mechanism that keeps off the position and feels, still mostly is mostly to reference pin formula selector, and generally adopts the cooperation to install fender position core bar and spring in the core bar hole, thereby core bar one end slides on the block that keeps off the position when shifting and produces the sense of shifting. However, for a multistable knob gear shifter with more gears, because the size of the multistable knob gear shifter is smaller than that of a gear lever type gear shifter, in order to avoid shaking of a gear core rod, a rotating part and the like, tolerance, assembly precision and the like need to be strictly controlled during design, and therefore production cost is high.

In addition, aiming at the matching mechanism of the gear core rod and the spring, the spring and the gear core rod are small in matching clearance in a small core rod hole, and in the process of each movement, because a certain clearance exists between the compression spring and the bushing as well as the gear shifting rod, the noise can be caused by the tiny clearance shaking, and in addition, the air trapping is easily caused by excessive grease lubrication, so that the sharp abnormal sound of exhaust can be generated during the gear shifting, and the noise is particularly obvious in the knob type gear shifter. Once the driver hears the sharp abnormal sound when shifting gears, the driver can attract the attention of the driver, and the driving safety is further not facilitated.
