Abstract
The utility model relates to a gear choosing and shifting force sensing block (1) which comprises a force sensing block body (11) fixedly connected with a gearshift shaft (2). A force sensing end face (12) contacting with a gear choosing and shifting positioning seat (3) is arranged on the top of the force sensing block body (11). The top of the vertical section of the force sensing end face (12) corresponding to the X-axis of the force sensing block body (11) is in corrugated shape with two peaks, and the top of the vertical section of the force sensing end face (12) along the Y-axis of the force sensing block body (11) is V-shaped. Since the top of the vertical section of the force sensing end face corresponding to the X-axis of the force sensing block body is in corrugated shape with two peaks, and the top of the vertical section of the force sensing end face corresponding to the Y-axis of the force sensing block body is V-shaped, the gear choosing and shifting positioning seat conducts curvilinear motion on the surface of the force sensing end face during contact cooperation between the force sensing end face and the gear choosing and shifting positioning seat. The corrugated shape enhances the force sensing effects.
Description
Technical field
The utility model relates to a kind of block selecting sense power structure in the manual gear of vehicle, relates in particular to a kind of choosing gearshift sense power piece, and simultaneously, the utility model also relates to the manual gear of vehicle gear shift mechanism with this choosing gearshift sense power piece.
Background technique
Along with developing of automobile industry, the Consumer requires increasingly high to the cornering ability of the type of manually keeping off a car, and the gearshift performance of automotive transmission directly has influence on the evaluation of driver to vehicle performance.The design of shifter of transmission directly influences the gearshift performance of speed changer.At present, with block selecting and separately design of gearshift, generally use two groups of block selecting positioning seats to accomplish the function of block selecting sense power and return and the function of gearshift sense power in the design of gearshift mechanism of automotive transmission; Use helical spring, spring seat, the snap ring that also has or use two opposed location of positioning seat to control the sense power and the return function of block selecting; Gearshift uses the neutral positioning seat to cooperate the function that realizes gearshift sense power with the gearshift line style, and the increase of its amount of parts causes the speed changer cost to increase, and uses helical spring to produce the mechanism of block selecting power; Part is many, the manufacturing assembling is wasted time and energy; Helical spring accuracy of manufacturing is low, and conformity is poor, causes block selecting power wayward.
China utility model patent CN201636307U discloses a kind of gearbox shifting structure, comprising that gearshift refers to, positioning seat, housing, gearshift axle, boss, refers to that with described gearshift the end face that contacts with positioning seat is the inclined-plane of V-arrangement indent; The seat head of positioning seat contacts with the bottom on inclined-plane, adopts this structure, avoids realizing through the spring returning device function of neutral location and block selecting return; It is simple in structure, and little to the spatial requirement in the gearbox, compactedness is strong; And rate of fault is low, and cost of production is low, and gearshift refers to cooperate with positioning seat; Strengthen the gearshift feel, promoted shift quality.But adopt this scheme, because the end face of choosing gearshift sense power piece is a V-arrangement, it is chosen when putting in place at gear, and gearshift refers to that the gearshift power inductive effects of (choosing gearshift sense power piece) is obvious inadequately, and the mode that installs and fixes of v-shaped structure and gearshift spool is unique, and versatility is lower.
Summary of the invention
