Description

Gear selector or control handle and electromechanical device

Technical Field

The invention relates to the mechanical field or the electromechanical field, in particular to a gear selector or a control handle and electromechanical equipment using the gear selector or the control handle.

Background

In the industrial control fields of port hoisting, engineering machinery, marine ships, high-speed rail vehicles, aerospace and the like, occasions in which the control part needs to be operated manually to realize the action of the machine are frequently seen. From flying tools, ships to automobiles and engineering machinery, a control handle or a gear selector is important equipment of an electronic control system and is a main human-computer interaction tool. For example, the highly integrated control functions of the control handle of a tacano series harvester manufactured by CLAAS company include the common functions of an additional device in the operation processes of lifting operation of a header, lifting and expanding operation of a header, rotation and extension operation of a grain bin discharge pipe switch and a discharge pipe, lifting operation of a winch and the like, and an operator can realize a control target only by operating a key in a cab. In the use process of the loader, the loader needs to frequently shift gears, even shifts gears while operating a working system, and needs a gear selector which has high integration level, reliable functions and good flexibility. Companies such as Gessmann, Germany, Penny + Giles (P + G), and the like have gear selectors or joysticks for harvesters or hydrostatic transmission control systems. However, the existing foreign products have complex structures, expensive selling prices and long supply periods, and domestic manufacturers are basically in the stage of simulation. At present, the operation handles or gear selectors on the market are various, and the function types and the applicable occasions are different. In some application occasions, the neutral locking function is a necessary function of the gear selector, so that accidents or casualties caused by misoperation are avoided; in addition, there are some vehicle requirements that the gear selector must be in a neutral locked position before the engine or other power or transmission device can be activated. In other applications, a signal to activate a reverse image or a reverse light, a reverse voice prompt, etc. may be required when the gear selector is in the reverse position.

At present, a control handle of a domestic harvester or a hydrostatic transmission control system simultaneously has a neutral locking function, neutral locking detection and/or reverse signal detection and convenient adjustment and repair after being worn, and a gear selector with the function that a lead in a sensor and the handle can penetrate out of the gear selector without being worn in use.

The front and rear gear signal identification sensor may be a micro switch or a proximity switch. The main structure of the sensor mounting frame is a right-angle structure.

The sensor mount 19 may also be integrated with the bottom dust cover 18 as a single piece, reducing tooling and assembly costs.

[ effect: when the wear-resistant plastic shell is a Z-shaped wear-resistant plastic shell, when the gear selector needs to work, the operating rod needs to be moved out of the middle position locking groove 209 of the wear-resistant plastic shell, so that the operating rod installation body or the operating rod combination can be driven to compress the guide cylindrical pin 9, and at the moment, the middle position locking return spring 7 can be compressed. When the operating rod swings forwards towards the sliding groove of the upper cover plate 210, at the moment, the compression of the middle locking return spring 7 is large, so that the friction force between the operating rod and the side wall of the operating rod guide groove of the wear-resistant plastic shell is also large; when the operating rod swings backwards towards the sliding groove 204 of the upper cover plate, at the moment, the compression of the middle locking return spring is small, so that the friction force between the operating rod and the section of the wear-resistant plastic shell is also small. When the operator stops working, the operating rod is only moved to the middle position, and the operating rod or the operating rod combination is automatically clamped into the groove 209 under the action of the reset pin 9. ]

As can be seen from fig. 11 and 21, the left core 11 and the right core 21 are formed with

grooves

1102 and 2104 for allowing the operating lever 1 to swing left and right therein.

Alternatively, as can be seen from fig. 38 and 39, an elastic member (e.g., disc spring assembly 5) is installed between the left core 11 and the first retaining member 4. Preferably, the disc spring assembly 5 is sleeved on the extended cylindrical body of the first limiting member 4. Alternatively, the disc spring assembly 5 is preferably fitted over the extended cylindrical body of the left core. Alternatively, as seen in fig. 38 and 39, the disc spring assembly 5 is fitted over the cylindrical outer surface 602 of the elastic member receiver disposed in the central bore of the left core. One or both ends of the disc spring assembly 5 are provided with a gasket or a gasket and a thrust washer 8. The other end of the spacer or washer is pressed by the left core 11 or the first stopper 4. The purpose of the mounting washer 8 is to prevent wear of the surfaces of the parts and to adjust the amount of compression of the disc spring assembly 5 or to adjust the clearance between the parts. In addition, the first limiting member 4 is installed on the housing 12 or in the inner hole 1216 of the housing 12 through an external thread, and when the force of the front and rear swinging of the operating rod needs to be adjusted, only the first limiting member 4 needs to be rotated. Because the left inner core 11 is under the action of positive pressure and friction force, the inner core can reliably stay at any position relative to the outer shell. The right inner core 21 receives a positive pressure and a frictional force of the adjacent components while the left inner core 11 receives a positive pressure and a frictional force. Preferably, a stud is inserted through the hole 1217 of the housing into the square slot 401 of the first retaining member to prevent the first retaining member from loosening relative to the housing 12. Similarly, to prevent wear of the component surfaces, a plastic thrust washer 22 is mounted in the right end face 2107 of the right core 21 or a groove in the right end face 2107.

Preferably, a stud is inserted into the hole 2106 of the right core to fix the rotating end 2402 of the angular displacement sensor, when the core rotates back and forth, one end of the sensor 24 is fixed relative to the second stopper 23 or the housing 12, and the other end 2402 can freely rotate along with the right core, so that the rotating angle of the core or the core combination or the operating rod can be sensed from the output of the sensor.

[ effect: the inner core or the inner core combination is directly or indirectly connected with an angular displacement sensor of analog quantity or digital quantity, and the output signal is the swing angle of the inner core relative to the shell. ]

The main body of the shell is a cylinder with square outside and round inside, which is convenient for processing or material drawing, cheap and small in processing amount. The cylindrical structure of the inner hole is convenient for forming a revolute pair with the inner core, and the processing is convenient; the entity between the inner cylindrical hole and the square outer wall is convenient for mounting related parts such as a mounting plate, a wear-resistant plastic shell, a bottom dust cover and a sensor mounting frame by adopting connecting pieces such as screws.

As shown in fig. 42, the middle position locking signal recognition sensor 10 is installed on the bottom surface of the housing, the reed of the microswitch 10 used as the middle position locking signal recognition sensor contacts with the rear edge 1302 of the transition piece 13, the front edge 1303 of the transition piece 13 acts with the extending end 1504 of the operation rod installation body, the transition piece 13 forms a revolute pair with the housing, and the installation hole 1301 of the transition piece 13 is coaxial with the transition piece positioning hole 1213 at the bottom of the housing; the transition piece rotates about the axis relative to the housing. This avoids direct impact of the movement of the lever or lever assembly on the mid-lock signal identification sensor 10. A microswitch 20, which serves as a front-rear catch signal identifying sensor, is mounted on the sensor mounting bracket 19 with its leaf 2001 partially extending into the slot 1210 in the housing 12, giving a signal of front-rear catch by distinguishing between different triggering or activation states of the sensor by the slot 2108 in the outer surface of the core right 21 and the outer surface of the housing 21 mounted in the housing bore.

The outer sleeve of the zipper is mounted on a zipper sleeve fixing ring 36, and the zipper sleeve fixing ring 36 is mounted on the zipper fixing frame 30. The zipper retainer 36 has holes for retaining a zipper sleeve. The zipper fixing ring 36 is connected with the cable fixing frame 30 in a rotating pair mode. The zipper mount 30 is fixedly connected to the housing or shell. The zipper slides or stretches in the zipper sleeve. Similarly, the slide fastener can be driven to extend and retract by the swinging of the cable swinging rod 28 to control the opening and closing of the clutch, the tightness of the brake, the displacement of the hydraulic pump or the motor, and the like. This allows control of the electromechanical device or vehicle, etc. to be achieved mechanically. Therefore, the sensor can be saved, other actuator related elements such as an accelerator actuator and the like can be omitted, the cost is saved, the function is reliable, and other characteristics of the design of the application are kept.
