Problems solved by technology
[0004] The gear shifting method of the existing tire paver is mainly to realize the wheel brake by stepping on the brake during driving or lock the mechanical gearbox, and return the handle to the neutral position to return the pump swash plate to the zero position to decelerate and stop. This shifting method is complicated to operate, the driver manually parks, and then manipulates the shifting mechanism to shift gears after stabilization
In the process of parking and shifting, when the shifting conditions are not met, forced shifting will cause the gears to fail to mesh normally, resulting in difficult shifting, shifting failure and other problems, and the need to stop and wait, human judgment, not smart

The invention provides a method for controlling automatic shifting of a paver, an automatic shifting control device and a tire paver. The method for controlling the automatic shifting of the paver includes: receiving a shift signal; reducing the speed of the input end of the gearbox of the paver according to the shift signal until the speed of the input end of the gearbox reaches a first preset value; detecting the speed of the gearbox The rotational speed of the input end until the rotational speed of the input end of the gearbox reaches the second preset value; perform a shift operation; according to the gear position corresponding to the shift signal, increase the rotational speed of the input end of the gearbox of the paver. The method for controlling the automatic shifting of the paver provided by the present invention automatically controls the appropriate shifting timing through the program, and automatically completes the shifting operation. gear, and can reduce the frustration during shifting and improve the smoothness of shifting.
Description
technical field [0001] The present invention relates to the technical field of engineering vehicles, in particular, to a method for controlling automatic gear shifting of a paver, and an automatic gear shifting control device for realizing the above-mentioned method for controlling automatic gear shifting of a paver, And a tire paver including the above-mentioned automatic shift control device. Background technique [0002] At present, the tire paver is widely used because of its good maneuverability, fast transition, and high construction efficiency. For example, it can be used for the construction of municipal, community, and garden roads. [0003] The tire paver is generally divided into low-speed gear and high-speed gear, corresponding to the tortoise gear and the rabbit gear. The speed of the tortoise gear is generally 0-24m / min, and the speed of the rabbit gear is generally 0-10km / h. The gearbox mainly changes the speed ratio to switch between high and low speeds to m...
