Multi-gear transmission operating system

Abstract

The invention belongs to the field of transmissions, and discloses a multi-gear transmission operating system. The multi-gear transmission operating system comprises an air reservoir, a middle position air cylinder assembly, a gear shifting rod, an operation hand ball, an air path control valve, a gear change shifting block, a single H valve, an auxiliary box shifting fork shaft and an air reservoir air outlet which are sequentially connected with a pressure regulating valve, a clutch separating pump switch, an interlocking valve and a backset cylinder; the air inlets of the operation hand ball and the air path control valve are connected with an air outlet of the pressure regulating valve correspondingly; the operation hand ball and the air path control valve are connected with the singleH valve, an air outlet of the single H valve is connected with a low gear side of the middle position air cylinder assembly and an air inlet at a high gear side, and a high-low gear pre-selection switch connected with the single H valve is arranged on the operation hand ball; one end of the auxiliary box shifting fork shaft is connected with the middle position air cylinder assembly, an interlocking control block is arranged on the other end of the auxiliary box shifting fork shaft, and a radial protruding block is arranged on the interlocking control block; one end of the gear change shifting block is connected with the air path control valve, and the other end of the gear change shifting block is connected with the gear shifting rod. According to the operating system, the damage to a synchronizer by misoperation is effectively prevented, the failure rate of the synchronizer is reduced, the vehicle is guaranteed to operate well, and the maintenance service cost is saved.

Description

technical field [0001] The invention belongs to the field of transmissions, and relates to a multi-gear transmission control system. Background technique [0002] With the increase of the first maintenance mileage, the increase of labor service costs and the intensification of market competition, how to improve the comfort and reliability of the manual transmission control system is particularly important. However, most commercial vehicle transmissions are affected by traditional design concepts. Only focus on product functions, not enough attention to shift comfort, resulting in large shift force. Although the transmission is equipped with a synchronizer, there is no need to shift gears with two feet of clutch, and it also avoids the noise caused by the tooth top teeth during the combination, which greatly improves the labor intensity and driving comfort of the driver. [0003] However, multi-gear transmissions, especially those with main and auxiliary transmission structu...
