It is including shifting fork, manipulator base, ratchet structure, its characterized in that: the gear shifting fork is internally provided with a stepped hole, the upper part of the gear shifting fork is provided with a large hole, the hole at the lower part of the gear shifting fork is smaller than the hole at the upper part of the gear shifting fork, the large hole is close to the lower part of the gear shifting fork and is provided with a circumferential groove matched with the elastic retainer ring, a conical positioning pin is arranged in the small hole, a compression spring is arranged in a cavity of the conical positioning pin, a baffle is arranged on the compression spring; the ratchet structure is detachably mounted on the base of the manipulator and is positioned by a conical locating pin in the shift fork. The split type design is adopted, the independently designed ratchet wheel structure is made of plastic and is arranged on the base of the manipulator, and the ratchet wheel structure has strong self-lubricating property, small abrasion and small noise with a positioning pin which is also made of plastic in the using process; in addition, the ratchet structure can be disassembled, and if the structure is damaged, the ratchet structure can be independently replaced without replacing the whole manipulator base.
Description
Technical Field
The utility model relates to an automobile manufacturing technical field, concretely relates to heavy-duty car flexible axle variable speed control ware.
Background
At present, a heavy truck is mostly matched with a manual gearbox and is controlled by a flexible shaft, the whole system has large clearance, and a neutral gear positioning function is required to be arranged on a manipulator for simplifying the installation procedure. The positioning structure used in the market at present is a ratchet structure directly cast on a base of a manipulator and is positioned by a plastic positioning pin. The design has the defects of weak self-lubricating property, large abrasion and large noise in the relative movement process of the positioning pin and the metal ratchet wheel structure; and because the ratchet structure is designed on the base of the manipulator, if the structure is damaged, the whole manipulator needs to be replaced.
Disclosure of Invention
The utility model aims at providing a heavy-duty car flexible axle variable speed control ware that wear-resisting, convenient maintenance.
The utility model discloses a shift fork, manipulator base, ratchet structure of shifting, its characterized in that: the gear shifting fork is internally provided with a stepped hole, the upper part of the gear shifting fork is provided with a large hole, the hole at the lower part of the gear shifting fork is smaller than the hole at the upper part of the gear shifting fork, the large hole is close to the lower part of the gear shifting fork and is provided with a circumferential groove matched with the elastic retainer ring, a conical positioning pin is arranged in the small hole, a compression spring is arranged in a cavity of the conical positioning pin, a baffle is arranged on the compression spring; the ratchet structure is detachably mounted on the base of the manipulator and is positioned by a conical locating pin in the shift fork.
The ratchet structure and the conical positioning pin are made of plastic materials.
The novel structure adopts a split type design, the independently designed ratchet wheel structure is made of plastic and is arranged on the base of the manipulator, and the ratchet wheel structure has strong self-lubricating property, small abrasion and small noise with a positioning pin which is also made of plastic in the using process; in addition, the ratchet structure can be disassembled, and if the structure is damaged, the ratchet structure can be independently replaced without replacing the whole manipulator base.
Compared with the prior art, the utility model has the advantages that:
the ratchet wheel and the positioning pin are both made of plastic materials, so that the self-lubricating property is strong, the abrasion is small, and the service life can be prolonged by about 40 percent; the noise is small in the motion process; in addition, the ratchet wheel can be detached, and if the ratchet wheel is damaged, the ratchet wheel structure can be independently replaced, so that the maintainability is high, and the maintenance cost is low.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1, elastic retainer ring; 2. a baffle plate; 3. a compression spring; 4. a conical locating pin; 5. a gear shifting fork; 6. a ratchet structure; 7. a manipulator base.
Detailed Description
As shown in the figure, the first and second,
the utility model comprises a gear shifting fork 5, a manipulator base 7 and a ratchet structure 6, wherein a stepped hole is arranged in the gear shifting fork 5, the upper part of the gear shifting fork 5 is a big hole, the hole at the lower part of the gear shifting fork is smaller than the hole at the upper part of the gear shifting fork, a circumferential groove matched with an elastic retainer ring 1 is arranged at the position, close to the lower part, of the big hole, a conical positioning pin 4 is arranged in the small hole, a compression spring 3 is arranged in a cavity of the conical positioning pin 4, a separation blade 2 is arranged on the compression spring 3; the ratchet structure 6 is detachably mounted on the manipulator base 7, and then the positioning pin 4 is aligned and pressed with the ratchet structure 6, and the shift fork 5 is mounted on the manipulator base 7 through a pin shaft. When the whole vehicle is used, if the ratchet wheel structure 6 is damaged or the service life is reached, the ratchet wheel structure 6 can be directly detached from the manipulator base 7 without replacing the whole manipulator base.
This novel structure adopts split type design, and the ratchet structure of independent design adopts the plastics material and installs on the manipulator base, and is strong, the wearing and tearing are little, the small in noise with the locating pin self-lubrication nature that is the plastics material equally in the use.
Claims (2)
1. The utility model provides a heavy-duty car flexible axle variable speed executor, includes shift fork, executor base, ratchet structure of shifting, its characterized in that: the gear shifting fork is internally provided with a stepped hole, the upper part of the gear shifting fork is provided with a large hole, the hole at the lower part of the gear shifting fork is smaller than the hole at the upper part of the gear shifting fork, the large hole is close to the lower part of the gear shifting fork and is provided with a circumferential groove matched with the elastic retainer ring, a conical positioning pin is arranged in the small hole, a compression spring is arranged in a cavity of the conical positioning pin, a baffle is arranged on the compression spring; the ratchet structure is detachably mounted on the base of the manipulator and is positioned by a conical locating pin in the shift fork.
