Problems solved by technology

Ordinary 8-speed heavy-duty transmission adopts 4X2 structure, used on mining vehicles, the auxiliary box synchronizer shifts frequently, and the reliability is poor; the transmission with more gears is used on mining vehicles, except for the auxiliary box synchronizer. The reliability is poor In addition, there are many gears, frequent gear changes, and easy driving fatigue. At the same time, practice has proved that the fuel consumption is greater; currently, the better 7DS series transmissions used in mining vehicles are limited by the structure, and the speed ratio is narrow, which cannot take into account the empty speed. Fast, large full-load bearing capacity, strong climbing ability, etc., the speed ratio is large, and the use of super-heavy mining vehicles is limited

Embodiment Construction

[0017] The present invention is described in further detail below in conjunction with accompanying drawing:

[0018] see figure 1 , the present invention is applicable to the 8-speed mining vehicle transmission, the 8-speed mining vehicle transmission adopts the main and auxiliary box structure, the main box has 7 forward gears, one reverse gear, and the auxiliary box has only overdrive gear. The working principle of the first two-position three-way valve 11 and the second two-position three-way valve 5 of the present invention is the same, when the contact is in a compressed state, the air inlet is connected to the air outlet, otherwise, the air outlet is connected to the exhaust hole . When the contact M of the preselection valve 10 is in the low gear area, the outlet pipe is connected to the intake pipe, the inlet J of the two-position five-way valve 12 is connected to the first outlet C1, and the second outlet C2 is connected to the second row. The air hole P2 is connect...

Abstract

The invention discloses a mining vehicle transmission control system. The mining vehicle transmission control system comprises a whole vehicle gas tank, and a first two-position three-way valve communicated with the whole vehicle gas tank, wherein the first two-position three-way valve is communicated with a secondary tank cylinder through a two-position five-way valve; and two gas outlets of the two-position five-way valve are respectively communicated with gas chambers at the two sides of a piston in the secondary tank cylinder for controlling a motion of the secondary tank piston to finish a gear shifting action. The mining vehicle transmission control system provides a control gas way to a 8-gear mining vehicle transmission, guarantees an overgear of the transmission to be only switched with a direct gear through the control of the two-position three-way valve, the two-position five-way valve and a pre-selection valve, effectively controls the secondary tank use frequency, prevents the gear-crossing operation of a secondary tank, reduces the fault rate of a secondary tank synchronizer, guarantees the service life of the secondary tank synchronizer, effectively prevents wrong operations or rule-breaking operations, and guarantees no gear disordering of the transmission.

Description

【Technical field】 [0001] The invention belongs to the technical field of transmissions, and relates to a transmission control system for mine vehicles. 【Background technique】 [0002] The manual transmission of mining vehicles is developing from the transmission of road vehicles to the transmission of special vehicles. At present, there is no 8-speed special transmission for mining vehicles at home and abroad. Ordinary 8-speed heavy-duty transmission adopts 4X2 structure, used on mining vehicles, the auxiliary box synchronizer shifts frequently, and the reliability is poor; the transmission with more gears is used on mining vehicles, except for the auxiliary box synchronizer. The reliability is poor In addition, there are many gears, frequent shifting, and easy driving fatigue. At the same time, practice has proved that the fuel consumption is greater; currently, the better 7DS series transmissions used in mining vehicles are limited by the structure, and the speed ratio is ...
