Problems solved by technology
[0004] 1. In the prior art, both ends of the spool spring in the damping valve of the shift lever operating mechanism are not all connected to the movable spool and the base of the damping spool, so that when an external force exceeds the force of the spool spring, In order to realize the damping effect, in actual use, especially when shifting while driving, the push rod must achieve a certain displacement damping effect, which leads to a jitter at each shifting moment, and it is impossible to achieve a smooth shifting
[0005] 2. The damping valve of the existing shift lever operating mechanism adopts figure 1 The technical solution is to close the damping valve by fixing the cover. In order to ensure the sealing performance, the sealing gasket will be used for sealing. The result is that this kind of gasket has a certain life span or is disposable, and oil leakage is prone to occur. The phenomenon affects the cleanliness of the vehicle, especially during maintenance, it is necessary to replace the gasket, which increases the cost of consumables

The invention relates to a damping valve of a variable-speed rod operating mechanism, which comprises a valve body, a valve spool, a push rod, a travel limiting spring seat, a travel limiting spring, a handle fixing plate, a break-point spring and a decompression spring. The valve body is an integral structure, the valve spool is provided with a damping hole and is directly connected with the lower end of the decompression spring, the upper end surface of the valve spool and the travel limiting spring are located on the same horizontal plane, the valve spool is a cylinder, the upper diameter of the cylinder is smaller than the lower diameter of the cylinder, a threaded mounting hole is arranged on the lower side of the valve body, the valve spool and corresponding components can be assembled in and disassembled from the mounting hole, and the mounting hole is plugged by a screw with a hole matching with the damping hole.
Description
technical field [0001] The invention relates to the field of automatic vehicles, in particular to a damping spool of a shift lever operating mechanism. Background technique [0002] During the driving of the vehicle, in order to adapt to different situations, the driving speed of the vehicle should be adjusted. The current adjustment of vehicle speed is mainly through the gear lever control mechanism, and there are two types of this control mechanism, one is through manual manipulation of the gear lever, and the other is through the accelerator to control the speed change, which is now called automatic transmission. device. [0003] In a manual transmission automatic car, the speed adjustment is achieved by pushing the gear lever operating mechanism by hand. In order to ensure the stability of the gear lever operating mechanism and reduce the vibration of the vehicle during driving, it will cause inaccurate gear shifting and reduce the speed change during gear shifting. In...
