Abstract

The utility model relates to a shifting fork mechanism for a passenger car manual transmission. The shifting fork mechanism for the passenger car manual transmission comprises a shifting shaft A and a shifting shaft B parallel to each other. The shifting shaft A is provided with a shifting fork A and a shifting block A. The shifting shaft B is provided with a shifting block B and a shifting fork B. Corresponding ends of the shifting block A and the shifting fork B are bent ends. A shifting finger is in an M shape, and finger grooves are reserved on two inner sides of the M shape. The bent end of the shifting block A is fitted and fastened into one finger groove of the M-shaped shifting finger, or the bent end of the shifting fork B is fitted and fastened into one finger groove of the M-shaped shifting finger. The shifting fork mechanism is reasonable in design and allows two gears (such as first gear and second gear) not to share one synchronizer, so that all gear pairs of the transmission are more flexibly distributed in the transmission.

Description

The selector fork mechanism that is used for the passenger car manual transmission
Technical field
The utility model belongs to the manual gear of vehicle technical field, is specifically related to the selector fork mechanism of manual gear of vehicle.
Background technique
The gearshift actuating device of traditional passenger car manual transmission is made up of choosing gearshift axle system and some selector forks system.Choosing gearshift axle system comprises that choosing gearshift axle and gearshift refer to, the selector fork system comprises gearshift axle, selector fork and gearshift shifting block.Because the restriction that arranged by car load shift handle gear, the gear of certain adjacent two gear (like a retaining and two retainings, three retainings and four retainings, five retainings and six retainings etc.) must use same synchronizer.For example, a retaining and two retainings are stressed bigger, in theory should be arranged apart in the position near spring bearing.But,, cause the gear of these two gears impossible arranged apart owing to must use same synchronizer.So traditional passenger car manual transmission gearshift has constituted bigger limiting factor to the layout of gear.
Summary of the invention
Can realize arranged apartly for the gear that satisfies adjacent two gears, the gear that makes manual transmission is more flexible with the layout of axle, and the utility model provides a kind of selector fork mechanism that is used for the passenger car manual transmission.
The technological scheme of the utility model is following:
The selector fork mechanism that is used for the passenger car manual transmission comprises the selector fork of gearshift axle and U-shaped; The selector fork of U-shaped is installed on the gearshift axle; Also be provided with the gearshift shifting block on the gearshift axle, cooperate with the gearshift shifting block being provided with gearshift and referring to, gearshift refers to offer the choosing axis hole of shifting gears; Comprise two gearshift axle A that laterally arrange and gearshift axle B, said gearshift axle A is provided with selector fork A and gearshift shifting block A; Gearshift axle B is provided with gearshift shifting block B and selector fork B; The corresponding end of said gearshift shifting block A and selector fork B is the crotch end; Said gearshift refers to the shape for M, and the both sides in the M shape are respectively the finger groove; The side that the crotch end of said gearshift shifting block A cooperates the gearshift that is buckled in M shape to refer to refers in the groove, or the opposite side that the crotch end of selector fork B cooperates the gearshift that is buckled in M shape to refer to refers in the groove.
The crotch end of said gearshift shifting block A is the U-shaped crotch, and the crotch end of said gearshift shifting block B is L shaped crotch.
The selector fork mechanism design of the utility model is reasonable, can realize that adjacent two gears (like a retaining and two retainings) needn't use same synchronizer, make the position of each shift gear pair of speed changer in speed changer more flexible.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 refers to the plan view (neutral state) of position relation for gearshift shifting block A, selector fork B and gearshift among Fig. 1.
Fig. 3 refers to and selector fork B mated condition figure (second gear state) for gearshift.
Fig. 4 refers to selector fork A mated condition figure (one grade of state) for gearshift.
Sequence number among the last figure: choosing gearshift axle 1, gearshift refer to 2, gearshift shifting block A3, gearshift shifting block B4, selector fork A5, a gearshift axle A6, selector fork B7, a gearshift axle B8.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done explanation further through embodiment.
Embodiment:
Referring to Fig. 1, the selector fork mechanism that is used for the passenger car manual transmission comprises two gearshift axle A6 that laterally arrange and gearshift axle B8, is installed with selector fork A5 on the side of gearshift axle A6, is installed with gearshift shifting block A3 on the opposite side; Be installed with gearshift shifting block B4 on the side of gearshift axle B8, opposite side is provided with selector fork B7.Gearshift shifting block A3 is corresponding with gearshift shifting block B4, and gearshift shifting block A3 is the crotch end with the corresponding end of gearshift shifting block B4, and the crotch end of gearshift shifting block A3 is the U-shaped crotch, and the crotch end of said gearshift shifting block B4 is L shaped crotch.Gearshift refers to 2 for M shape, and the both sides in the M shape are respectively the finger groove, and gearshift refers to 2 both sides to refer to groove, and the crotch end with gearshift shifting block A3 is corresponding with the crotch end of gearshift shifting block B4 respectively, sees Fig. 2; The crotch end of gearshift shifting block A3 cooperates the gearshift that is buckled in M shape to refer to that a side of 2 refers in the groove, or the crotch end of gearshift shifting block B4 cooperates the gearshift that is buckled in M shape to refer to that a side of 2 refers in the groove.
During use, gearshift refers to that 2 are fixedly mounted on the choosing gearshift axle 1 of speed changer.When speed changer was operated in neutral, shown in accompanying drawing 2, gearshift referred to 2 with gearshift shifting block A3 with shift gears and to have gap delta respectively between the shifting block B4, sees Fig. 2.
When speed changer changes in the process of two retainings, shown in accompanying drawing 3, gearshift refers to 2 around choosing gearshift axle 1 clockwise direction angle of swing α; Gearshift shifting block B4 moves right; Gearshift axle B8 and selector fork B7 move right simultaneously, two retaining synchronizer work, and speed changer is operated in two retainings.In this process, gearshift shifting block A3, gearshift axle A6, selector fork A5 and a retaining synchronizer attonity.
When speed changer changes to a retaining by two retainings, experience two stages altogether: be changed to neutral by two retainings, be changed to one grade by neutral.
By two retainings when being changed to neutral, shown in accompanying drawing 3, gearshift refers to 2, and to exist with gearshift shifting block B4 highly be that overlapping of h is regional; Gearshift refers to 2 when choosing gearshift axle 1 counter clockwise direction angle of swing α gets back to neutral gear position; Gearshift shifting block B4 is moved to the left, and gearshift axle B8 and selector fork B7 are moved to the left simultaneously, and two retaining synchronizers are got back to neutral gear position; Speed changer is operated in neutral, state as shown in Figure 2.In this process, gearshift shifting block A3, gearshift axle A6, selector fork A5 and a retaining synchronizer attonity.
When being changed to one grade by neutral, as shown in Figure 4, gearshift refers to 2 around choosing gearshift axle 1 counter clockwise direction angle of swing α, and gearshift shifting block A3 is moved to the left, and gearshift axle A6 and selector fork A5 are moved to the left simultaneously, a retaining synchronizer job, and speed changer is operated in a retaining.In this process, gearshift shifting block B4, gearshift axle B8, selector fork B7 and two retaining synchronizer attonitys.
More than in the narration, " retaining " and " two retainings " only illustrates as an example that replaceable is any gear of speed changer.
