Abstract
A shift control and stepless speed regulation composite control device comprises a base, a locking nut, a bow-shaped arm, a stepless speed regulation rotary arm shaft, a control lever, a handle ball, a shift rotary arm shaft, a return supporting plate, a return torsional spring, a limiting plate, an abrasion-resistant lining, a stepless speed regulation flexible shaft arm and a shift speed regulation flexible shaft arm. The shift control and stepless speed regulation composite control device is characterized in that the control lever drives the shift rotary arm shaft and the stepless speed regulation rotary arm shaft to achieve independent rotation of the shift rotary arm shaft and the stepless speed regulation rotary arm shaft, the shift rotary arm shaft is fixed onto the base, the stepless speed regulation rotary arm shaft is fixed onto the shift rotary arm shaft, the bow-shaped arm and the stepless speed regulation flexible shaft arm are fixed, and the shift rotary arm shaft and the shift speed regulation flexible shaft arm are fixed. The variable speed control device is convenient to control and reliable to use, high-gear and low-gear mechanical gearboxes and hydraulic stepless variable pumps-quantitative or variable motor hydraulic systems can be controlled through one handle, and stepless variable speed control is achieved.
Description
Technical field
The utility model relates to a kind of gear controller, relates in particular to the compound steering unit that can realize shift control and stepless speed regulation.
Background technique
Gear controller is the key mechanism that work, traveling vehicle carry out gear change.Current walking stepless change generally has two kinds of modes: one is gearbox+mechanical stepless speed changes mechanism; Another kind is gearbox+hydraulic stepless speed changing machine structure.At present the selector gear of use is generally to adopt independently two Joysticks to realize, and one is shift handle, independent gearbox advance each speed gear and the reverse gear position controlled, and the action of Joystick shift is divided into two course of action of gear selecting+gear shift; Another is stepless change handle, and this handle, by the hydraulic stepless speed changing machine structure of hydraulic element control machinery stepless speed changing mechanism or variable displacement pump and oil hydraulic motor composition, is realized stepless change control by stages, and control action is loaded down with trivial details, mechanism's complexity, and cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of compound steering unit of realizing shift control and stepless speed regulation, and this compound steering unit handiness, use are reliably.
The purpose of this utility model is achieved through the following technical solutions: a kind of shift control and stepless speed regulation compound steering unit, comprise: base, lock-nut, bow word arm, stepless speed regulation tumbler shaft, operating handle, handle ball, shift tumbler shaft, return support plate, return torsion spring, limiting board, anti-wearing liner, stepless speed regulation flexible axle arm, shift speed governing flexible axle arm, it is characterized in that driving shift tumbler shaft and stepless speed regulation tumbler shaft with an operating handle, realize its rotation separately separately, shift tumbler shaft is fixed on base, stepless speed regulation tumbler shaft is fixed on shift tumbler shaft, bow word arm and stepless speed regulation flexible axle arm are fixed, shift tumbler shaft and shift speed governing flexible axle arm are fixed.
Bow word arm described in technique scheme is arranged on base, realize revolution, both sides rotary hole center superposition, on bow word arm, have slot to make way, allow operating handle pass, work the effect of move and step down of transmission, bending word revolution of arm process can self-locking, and self-locking process is by bolt, double nut, asbestos packing realization.
In technique scheme for avoiding operating handle to produce and rock in the course of the work, at top mounting limit plate.
An operating handle control high and low shelves mechanical gear box and hydraulic stepless variable displacement pump-quantitative or variable displacement motor hydraulic system for the utility model, realize stepless change control, this apparatus structure is simple, alleviate tractor driver's operation intensity, improve the automatization level of application vehicle, and mechanism's long service life.
brief description of the drawingsfig. 1 is structural representation of the present utility model (front elevation).
Fig. 2 is structural representation of the present utility model (profile).
Fig. 3 is limiting board schematic diagram of the present utility model.
In figure, base (1), lock-nut (2), bow word arm (3), stepless speed regulation tumbler shaft (4), behaviour
Vertical pole (5), handle ball (6), shift tumbler shaft (7), return support plate (8), return torsion spring (9), limiting board (10), anti-wearing liner (11), stepless speed regulation flexible axle arm (12), shift speed governing flexible axle arm (13).
embodimentbelow in conjunction with drawings and Examples, the utility model is described in further detail.
In the present embodiment, entirety shift control and stepless speed regulation compound steering unit are installed on above operator cabin control box, operating handle (5) is by shift tumbler shaft (7) rotation, the pushing-pulling flexible shaft heart yearn push-and-pull (not illustrated in FIG.) that drives shift speed governing flexible axle arm (13) to connect, drive gearshift shaft of change gear case push-and-pull (not illustrated in FIG.), realize high (walking), the engagement of low (work) shelves gear and throw off, completing shift control.In operating handle (5) rotation process, bow word arm (3) horizontal stationary, operating handle (5) is by bending the middle slotted hole slot to make way of word arm (3) by operating handle (5) rotation.Operating handle (5) rotates by stepless change tumbler shaft (4), promote bow word arm (3) rotation, the pushing-pulling flexible shaft heart yearn push-and-pull (not illustrated in FIG.) that drives stepless speed regulation flexible axle arm (12) to connect, promote hydraulic variable displacement pump control arm rotation (not illustrated in FIG.), realize the vehicle stepless change speed control that moves forward and backward.Wherein return torsion spring (9) is stirred return support plate (8) and is made operating handle (5) can automatically get back to neutral gear meta, and anti-wearing liner (11) is wear-resisting nonmetallic material, improves mechanism working life.Bow word arm (3) locking, motor function are by the suitably impacting force realization of lock-nut (2), the thin pad of asbestos (not illustrated in FIG.) and connecting bolt (not illustrated in FIG.).For avoiding operating handle to produce and rock in the course of the work, at top mounting limit plate (10).
