Abstract

The invention relates to a variable-speed control mechanism, and belongs to parts of heavy-duty cars. The variable-speed control mechanism is composed of a variable-speed gear lever, a controller, a double-transmission universal joint I, a double-transmission universal joint II, a telescopic rod, an actuator, an execution rod and a tie rod. According to the variable-speed control mechanism adopting the telescopic rod, gear selecting and gear shifting motion of the variable-speed gear lever can be converted into rotation of an inner shaft and an outer shaft of the telescopic rod, then the rotation of the telescopic rod can be restored back to gear selecting and gear shifting motion of the execution rod through the actuator, a transmission is driven to realize gear selecting and gear shifting, in the moving process of a cab, motion interference can be eliminated through telescoping of the telescopic rod, and therefore motion interference cannot be generated, and the operation precision can be improved.

Description

technical field [0001] The invention belongs to heavy-duty automobile parts, in particular to a speed change control mechanism. Background technique [0002] There are currently three types of manual transmission control systems for heavy-duty vehicles: 1. Hard rod transmission control systems; 2. Soft shaft transmission control systems; 3. Telescopic rod and force converter control systems. [0003] During the use of the prior art telescopic rod shift control system for automobiles, the movement of the cab drives the telescopic rod to move relative to the gearbox, thereby causing motion interference in the control system. Appropriately increasing the clearance will affect the steering accuracy and make the gear unclear. Contents of the invention [0004] The invention provides a speed change control mechanism to solve the problem of motion interference when the cab moves. [0005] The technical scheme adopted by the present invention is composed of a gear shift lever, a...
