The transmission gear selection return device comprises a first gear return spring, a second gear return spring and a reverse gear return spring, wherein a control shaft is sleeved with the first gear return spring and the second gear return spring. A limiting plate is arranged on the control shaft, the limiting plate is tightly attached to a spring seat, the reverse gear return spring is arranged in a groove of the spring seat, the other end of the reverse gear return spring is connected with a limiting lining, the control shaft is sleeved with the limiting lining, the limiting lining is sleeved with a baffle, the baffle is fixedly connected with a control shaft shell, the control shaft is sleeved with the control shaft shell, one end of the limiting lining is tightly attached to a control shaft gear selection handle, and the control shaft gear selection handle is connected with the control shaft through a hinge pin. The transmission gear selection return device is compact in structure, reasonable in design, convenient to obtain and beneficial to spatial arrangement, the structure can be installed and detached at the same time and does not need to be detached respectively, detaching time is saved, convenience is provided for production and maintenance, the length of the control shaft is lowered, and cost is saved.
Description
Technical field
The utility model relates to a kind of returning device, is specifically related to a kind of speed changer block selecting returning device.
Background technique
At present, in the manual transmission gear selection mechanism existing on market, must guarantee with returning device the accuracy of neutral gear position.Existing manual transmission block selecting returning device generally adopts return spring and limit stoper to realize neutral return function, but the gear of one, two in block selecting returning device block selecting spring and five, the block selecting spring that reverses gear are arranged in the both sides of Control Shaft, occupy larger space, dismounting is inconvenient, structure is compact not.
Summary of the invention
The purpose of this utility model is to overcome the deficiency existing in above-mentioned technology, and a kind of compact structure, reasonable in design is provided, and is convenient to installation and removal, and can save the speed changer block selecting returning device of Control Shaft space, compact structure.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise one, two gear return springs and the return spring that reverses gear, described one, two gear return springs are nested with on Control Shaft, limiting board is installed on Control Shaft, limiting board and spring seat one end are close to, in the groove of spring seat, the return spring that reverses gear is installed, the return spring the other end that reverses gear is connected with limiting bush, limiting bush is nested with on Control Shaft, on limiting bush, be equipped with baffle plate, baffle plate is fixedly connected with Control Shaft housing, Control Shaft housing is nested with on Control Shaft, described limiting bush one end and Control Shaft block selecting handle are close to, Control Shaft block selecting handle is connected with Control Shaft by bearing pin.
The utility model has the advantages that:
1, compact structure, reasonable in design, is convenient to realize;
2, space is arranged favourablely, and structure can be carried out in installation and removal simultaneously, does not need to carry out respectively dismounting, has saved the time of dismounting, for producing and maintenance is provided convenience;
3, reduce the length of Control Shaft, saved cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model comprises one, two gear return spring 1 and the return springs 3 that reverse gear, described one, two gear return springs 1 are nested with on Control Shaft 7, limiting board 10 is installed on Control Shaft 7, limiting board 10 is close to spring seat 8 one end, the return spring 3 that reverses gear is installed in the groove of spring seat 8, return spring 3 the other ends that reverse gear are connected with limiting bush 4, limiting bush 4 is nested with on Control Shaft 7, on limiting bush 4, be equipped with baffle plate 9, baffle plate 9 is fixedly connected with Control Shaft housing 2, Control Shaft housing 2 is nested with on Control Shaft 7, described limiting bush 4 one end and Control Shaft block selecting handle 6 are close to, Control Shaft block selecting handle 6 is connected with Control Shaft 7 by bearing pin 5.
Described limiting board 10 is parallel with baffle plate 9.
Neutral gear position of the present utility model by one, second gear return spring 1 determines with the pretightening force of the return spring 3 that reverses gear, the position in both pretightening force balances.Because Control Shaft block selecting handle 6 is connected by bearing pin 5 with Control Shaft 7, when pulling Control Shaft block selecting handle 6 left, Control Shaft 7 will, to left movement, drive limiting board 10 motions, and then compress one, second gear return spring 1, overcome the power that spring is compressed generation and be one, two gear block selecting power.When pulling Control Shaft block selecting handle 6 to the right, Control Shaft 7 will move right, thereby drive limiting board 10 to move right, and then the compression return spring 3 that reverses gear, because limiting bush 4 step surfaces and baffle plate 9 are close to, baffle plate 9 is fixed on to be controlled on columella body 2, thereby the stroke of the return spring 3 that reverses gear is restricted, and the power that overcomes spring-compressed is the block selecting power of reversing gear.
